Various Terms for Smart Glass Smart Glass Switch Glass Switchable Glass Smart Windows Intelligent Glass Liquid Crystal Glass Dynamic Glass LCD Glass PDLC Glass Electronic Glass Dimmable Glass Clear to Opaque Glass Electric Glass Self-tinting Windows Applications for PDLC switchable glass range from residential to corporate to health care and retail, while the practical, functional benefits include privacy, display, energy savings, comfort and, it must be said, the wow factor. That wow factor comes alive in an open-concept law office, for example, where a centrally located conference room bounded by clear glazing becomes a private sanctuary for client meetings and depositions after the glazing turns opaque with the flip of a switch or building system control through automation integration. In a residential setting, the occupants enjoy unobstructed city or landscape views from extensive lavatory or bathing area glazing, and then enjoy the privacy of opaque/tinted glass when privacy is desired, again with the push of a button or even commands from a smart phone or home automation system. In retail or health care, spaces are fully exposed or protected with privacy as needs and wants indicate. In retail or auto dealer environments, projected videos can attract customers. The range of applications for PDLC smart glass will be examined more thoroughly at the end of the course. But first, it`s helpful to understand each of the major technologies used for switchable glass, and to understand the benefits and drawbacks of each technology in order to select the right specification for the project. Passive and Active Smart Glass Technologies and Their Best Applications Smart glass technologies include photochromic, thermochromic, electrochromic, suspended particle, and liquid crystal device technologies. While the basic concept behind all smart windows is the same, they can be made in several different ways, each with a different method and properties for blocking light and/or views. Critical aspects of smart glass include material costs, installation costs, electricity costs and durability, as well as functional features such as the speed of control, possibilities for dimming, and the degree of transparency. Smart glass technologies fall into two categories: passive and active. Active Smart Glass Technologies Active smart glass technologies respond to an electrical stimulus and are therefore controllable by the user. They include electrochromic, suspended particle device (SPD) and polymer dispersed liquid crystal (PDLC) technologies. Passive Smart Glass Technologies Passive smart glass technologies respond to non-electrical stimuli and thus cannot be controlled manually. These include thermochromic, which reacts to heat, and photochromic, which responds to light. A simplistic view of thermochromic windows is that the windows are tinted during the summer and are clear during the winter, with the assumption that thermochromic windows switch based on outdoor air temperature. Photochromic simply means something that changes color in response to light. In relation to sunglasses, photochromic lenses darken or lighten depending on their exposure to ultraviolet (UV) radiation. Photochromic technology is mostly used in eyeglasses (which tint depending on the amount of light). With these technologies, glass will limit or expand light transmission depending on the temperature or the amount of light present. For window glass, the timing factor could be problematic. Anyone who has gone from outdoors to indoors wearing these photochromic glasses, and has had to deal with the issue of glasses still darkened from the outside light, could see the advantage of controlling the lightening or darkening depending on one`s needs and circumstances. Electrochromic Electrochromic uses electricity to turn the glass from clear to dark. Electrochromic glass is typically used for solar control on exterior glass. The visible light transmission in the darkest state can be less than 3%. The resulting shading has limited privacy function as it can still be seen through. Electrochromic windows consist of two glass panes with several layers sandwiched in between. It works by passing low-voltage electrical charges across a microscopically thin, clear conductive coating on the glass surface, which activates electrochromic layers that change color from clear to dark. The electric current can be activated manually or by sensors which react to light intensity. One advantage of the electrochromic smart window is that it only requires electricity to change its opacity, but not to maintain a particular shade. This type of technology requires new glass installation, as there is no commercial film option to apply on existing glass. The switching speed of electrochromic glass is very slow and varies depending upon the size of the panel (larger panels typically take many minutes to switch). The consistency of tint changes also varies, with larger panels sometimes exhibiting tint changes that begin at the glazing`s outer edges and then move inward (known as the [iris effect"). Suspended Particle Device Technology In SPD technology, when voltage is applied, the suspended particles align and let light pass. Suspended particle devices (SPDs) respond to AC power to turn the glass from dark to clear. SPDs are ideal for such light control applications as skylights, auto glass, sunroofs, aircraft windows, and marine windows and portholes. In suspended particle devices (SPDs), a thin film laminate of rod-like nano-scale particles is suspended in a liquid and placed between two pieces of glass or plastic, or attached to one layer. When no voltage is applied, the suspended particles are randomly organized, thus blocking and absorbing light. When voltage is applied, the suspended particles align and let light pass. Varying the voltage of the film varies the orientation of the suspended particles, thereby regulating the tint of the glazing and the amount of light transmitted. The visible light transmission at the darkest state of SPD glazing is around 0.5% and the process takes one to three seconds after power is applied, regardless of the size of the window. The resulting dark blue shading blocks light and provides only partial privacy. Polymer Dispersed Liquid Crystal Switchable Technology The third type of active smart glass technology, and the focus of this learning unit, is polymer dispersed liquid crystal (PDLC). This technology controls light diffusion to turn the glazing from opaque to clear using AC power. In this technology, the glazing goes from opaque to clear or from clear to opaque in milliseconds, regardless of the window size. In the opaque state, more than 96% of the parallel light is blocked resulting in excellent privacy although around 80% of the total light transmits through the glazing. When switched to clear, you can see through the material like a piece of glass with about 86% total light transmission. We`ll examine how this technology works in the next section.

Whether in life or work, we often need a relatively quiet indoor sound environment, such as telephone calls, business negotiations, games, live broadcasts, vocal practice, entertainment, audio and video, etc. On the one hand, it can prevent noise from affecting others, and at the same time avoid being disturbed by noise from others or the outside world. On the other hand, it can protect our language privacy. The soundproof cabin is a soundproof product specially developed to meet this demand, which can provide you with a quiet "foothold". The soundproof cabin is also called the silent cabin, which can provide an echo-free and comfortable sound environment to ensure that you can focus on creation, study or rest. The soundproof cabin is equipped with multi-sided floor-to-ceiling soundproof glass walls, which maintain a certain degree of openness and light transmission, allowing you to be in it without restraint and oppression. The soundproof cabin has a built-in ventilation system, allowing you to still have a fresh feeling like a spring breeze in a relatively confined space environment, and always maintain the convection of internal and external air. The soundproof cabin has a built-in adjustable lighting system to maintain proper illuminance, so that your eyes will not feel tired. In addition, a wealth of power extension interfaces can meet the needs of various electrical equipment. The soundproof bin has a modular design, quick installation, "ready to use", and can be equipped with casters to realize a certain range of movement. When you need to change it to a new home, it can be easily disassembled and reorganized. The soundproof cabin adopts aluminum profile frame, metal shell, and electrostatic spraying process, which is beautiful and generous. The interior panel is an environmentally friendly sound-absorbing decorative material, which can effectively control the reverberation time in the cabin and ensure a good sound quality in the cabin. The floor is composed of multiple layers of vibration insulation layer, sound insulation layer, and non-slip decorative layer to isolate the sound insulation warehouse from the structure noise transmission path of the ground. Large-area transparent glass doors and windows are made of multilayer laminated safety glass to form a hollow structure, sound insulation and heat preservation. Through sophisticated processing and production technology and precise assembly and occlusal design, the overall sealing of the sound insulation warehouse is very good, which provides an important guarantee for the good sound insulation effect of the sound insulation warehouse.

Clear Switchable Smart Glass and PDLC Smart Film is a new type of special photoelectric glass product that combines ITO liquid crystal film into the middle of two layers of glass and forms a sandwich structure after high temperature and high pressure gluing. The user controls the transparency and opacity of the Smart Glass by PDLC Film Power Supply whether the current is on or off. The glass itself not only has all the characteristics of safety glass, but also has the privacy protection function to control the transparency of glass. Clear Switchable Smart Glass can be used in museums, exhibition halls, shopping malls, banks and other places for privacy, security and sound insulation, to prevent theft. However, there are some limitations to the installation process. 1, the limitation of High Transparency Self Adhesive Smart Film installation conditions Under normal circumstances, glass transverse walls, doors and Windows, curtain walls do not need electricity, but glass spraying installation needs wiring, which is a great test for builders. Applied to partition walls is good, but large area curtain wall also has various problems. Especially for mobile doors and Windows, no contact people do not know how to install PDLC Switchable Film and Smart Glass. If wiring is not considered properly, wiring will go to the outside of the aluminum frame, which is not beautiful and easy to damage. Electronically controlled spraying glass is more and more common in indoor use, and its advantages are obvious. It certainly reduces a lot of maintenance problems compared to blinds. 2, PDLC Switchalbe Film and Smart Glass size restrictions Three commonly used Smart Glass size is: 5mm or 6mm commonly used 2200*1650, 1830*2440, 2440*3660, 8mm and 10mm glass size: 1830*2440, 3300*2440, 3660*2440, 3300; The size of light glass is relatively large, about 1800mm*3500mm on one side. In comparison, the width of the original piece of Smart Glass is more than 2 meters, but there is no such a large spray glass. The larger the size of spray glass, the higher the risk of manufacturing and use. Because the LCD screen does not have the ability to adhere to plastic sprayed glass, there is a risk of delamination under too much pressure, and large glass transportation, handling, installation and other inconvenience, so the recommended size is as small as possible. 3, climate and environmental constraints Smart glass works at -20° C to 60°C. If the temperature is too high or too low, will affect the performance of liquid crystal film. PDLC Smart Glass in outdoor use, especially in summer, directly exposed to the sun, the temperature can reach more than 60 degrees, so that the PDLC Switchable Film inactivation. Prolonged exposure to high or low temperatures can cause irreversible damage to glass atomization. Affect service life. Therefore, we do not recommend using it outdoors or in cold climates. In use, special protection is required to accept a relatively short service life.

The LED transparent screen adopts RGB magic light beads, which are made into unit modules. By splicing the modules, an LED display of any size can be formed to display text, images, videos and other pictures. The screen size is adjustable, the grayscale is adjustable, and the color can be adjusted. It is a high-tech display product with multiple scalability, which can be widely used in glass curtain wall, lighting quantification, advertising media, space decoration, partition decoration, home design, commercial display, functional signage, etc. You must not be unfamiliar with LED Displays, but you may not know much about LED glass screens. LED Glass curtain wall, LED display is also called LED glass screen, it is a kind of bright screen, with the characteristics of light and transparent. LED glass screens are generally installed in the glass of buildings, which not only has the practicability of traditional display screens, but also has certain aesthetics and concealment.

PDLC (Polymer Dispersed Liquid Crystal) liquid crystal electronically controlled dimming film can be adjusted by voltage to realize the conversion between transparent and opaque glass. The power-on state is transparent, and the power-off state is frosted. It can be used for laminating finished dimming glass or for making back-mounted liquid crystal film for projection. With the help of the electric field principle of the dimming liquid crystal glass, while maintaining the permeability of the space, it can conveniently protect the privacy. The liquid crystal dimming film on the market is bette 1. For the production of laminated dimming glass PDLC dimming liquid crystal film can be used to process the finished dimming glass with sandwich structure. In order to ensure the best physical properties and life of the finished dimming glass, PVB is usually used for processing, and inferior EVA materials are not recommended for processing. While it is convenient to control the transparency and opacity of the glass, the dimming glass has various excellent performances such as safety, environmental protection and sound insulation. 2. Used to make back-mounted liquid crystal dimming film The back-mounted film is mainly used in various rear projection fields and is one of the best projection screens on the market.

With the popularity of smart home PDLC Film The voice of intelligent Glass control is getting higher and higher In the realization of privacy protection, health, visual enjoyment, etc. People put forward higher requirements for modern buildings, especially bedrooms With the popularity of smart home The voice of intelligent control is getting higher and higher In the realization of privacy protection, health, visual enjoyment, etc. People put forward higher requirements for modern buildings, especially bedrooms Dimming glass can easily meet people's many requirements for the bedroom, Smart Glass can make full use of natural light sources, Allowing the house to get the maximum amount of light, while ensuring absolute privacy. It is integrated with the building, transparent and bright, as simple as invisible

Humans need natural daylight. Exposure to natural light is good for our body, for example, producing more vitamin D in our body, promoting better sleep, improving our moods, etc. In fact, nowadays most people spend the majority of our days indoors, moving between our homes and offices, two dots in one line. Modern architectural design has already begun to recognize the importance of letting natural light back into our lives, using glass in new and exciting ways. Large, often floor-to-ceiling glass windows help to bring the sunlight outside in. However, while this helps to create light-filled buildings, it can also increase building temperatures and personal discomfort for those sitting in direct sunlight. In particular, in office environments, the need to reduce glare on screens, control room temperatures or create private meeting spaces means we`re still using blinds and partitions to shut ourselves away from the outdoors and natural light. Increased temperatures also create more demand for air conditioning, while the use of window blinds means relying on additional artificial light. All of this can considerably increase a building`s energy usage and environmental footprint. This poses the question: How do we balance our human need for natural light with the environmental considerations of modern glass facade design and privacy requirements? With the development of liquid crystal technology (PDLC), we have found a perfect solution- PDLC Smart Film. When the small electrical supply is switched on, Liquid Crystal Molecules align and incident light passes through -- Smart Film instantly clears. When the power is switched off, Liquid Crystal molecules are randomly oriented, scattering light -- Smart Film becomes opaque (frosted, private). There are two types of Smart Film: 1. Self-Adhesive Smart Film for Existing Glass High Transparency Self Adhesive Smart Film applies to existing glass surface, allowing any piece of existing glass to become Smart Glass. A simple ON – OFF mode switches the glass from clear (transparent) to frosted (opaque). 2. Non-Adhesive Smart Film for producing Laminated Smart Glass Laminate non-adhesive Smart Film between two tempered glass panels -- Smart Glass. (Original article.

This technology will switch the smart glass/smart film from transparent state to an opaque translucent state with the simple flip of a wall switch, tap of an APP, click of a remote controller, or any smart home control system. The technology makes available a dynamic space that can be both private and open at the same time. Uses of switchable privacy glass include: • Residential – bathroom / shower enclosures, partitions • Commercial – conference rooms, office doors/partitions, reception • Retail – changing rooms, projection displays • Healthcare: ICU Doors, Nurseries, ERs, ORs, clinic partitions • Hospitality – bathroom /shower enclosures, partitions • Banking – ballistic teller lines, transaction windows, safe deposit rooms The Principal When the power is off the liquid crystal molecules are randomly oriented and will scatter incidental light. This renders the Switchable Privacy Glass panel opaque. When an electric current is applied, the liquid crystal molecules line up, the incidental light passes through, and the privacy glass becomes clear. Privacy Glass is a laminated glass. The laminated material within is Liquid Crystal Privacy Film, which responds to an electrical current. When electricity is applied to the film via the wiring, the liquid crystals align and the glass instantly becomes clear. When the power is turned off, the liquid crystals return to their normal scattered positions rendering the glass an opaque translucent. Technology PDLC (Polymer Dispersed Liquid Crystal) is a medium whose light scattering power is adjustable through applying an electric field. In their natural (uncharged) state, the PDLC droplets randomly align. PDLC Film consists of a polymer matrix of liquid crystals enclosed by electrically conductive Indium Tin Oxide-coated PET film. The resulting PDLC Film has wiring attached to a conductive copper strip (busbar) along the film`s edge. In a low voltage platform, this wiring is connected to a step-down transformer through which power is supplied for the [on" (clear) state. In their natural (uncharged) state, the PDLC droplets randomly align, thus creating the an opaque translucent condition. Two sheets of glass are laminated over the PDLC film. The components are assembled under high pressure and temperature to form a single unit. The ordinary refractive index of these liquid crystals does not match that of the polymer, and the incident light is thus scattered, resulting in a translucent state. When an electric field is applied across the material, the PDLC droplets re-orient, and subsequently the extraordinary refractive index of the liquid crystal matches that of the polymer. Therefore, the incident light can pass through, resulting in a transparent state. Shenzhen Yuguang is one of the biggest smart glass PDLC film manufacturer in China.

While Smart Film appears expensive, it disposes of the need to buy blinds or shades or cutains for protection. Also it diminishes energy cost and cleaning costs. So we are looking at an investment in your place that will recover itself over time. The price of this technology is made of not only the aesthetics, but also a list of benefits that save you money, time and protect your health. Energy Savings Smart Film permits sunlight to move through spaces. When the smart film is turned off and hazy, it still allows natural light inside your space, around 60%~70% of the daylight will still manage to enter the rooms, this way limiting the requirement for artificial light use. Also, smart film is proven to minimize the effects of high/low external temperatures from affecting your interior temperature, essentially saving you on energy costs. Operating at 60V AC, smart film consumes less than 5 Watt per sqm when on (transparent) and 0 Watts when off (frosted), making it great for your pocket as well as our planet. Saving on Design Smart Film and Smart Glass are extraordinary for a clean, minimal look that doesn`t become dated. While nordinary drapes or blinds become outdated overtime, clear glass that can easily be changed from transparent to opaque will consistently look elegant and never look old or obsolete. Long term, smart film will save you the expense and bother of refreshing your draperies or blinds to stay aware of the most recent trends. Saving on Cleaning Simple blinds and shades require regular cleaning, washing or even dry cleaning. Smart glass and film are cleaned much the same as ordinary glass, no exceptional treatment, instruments or solutions required. Over the long run, this can set aside your time and cash.

Advantage of Transparent LED Glass 1. High transparency, high light transmittance The glass curtain wall Transparent LED Display (also known as "Transparent LED Screen") has a permeability of 65% to 90%, and each LED light bar is only 2mm thick, and the gaps between the light bars are parallel to form a transparent effect. It is generally installed on the inside of the glass curtain wall of a commercial building, and installed indoors for outdoor displays, which completely breaks the limitations of traditional LED Displays on glass. With different types:P5*P10 Transparent LED Screen,P10*P10 Transparent LED Screen,P10*P20 Transparent LED Screen,P20*P20 Transparent LED Screen 2. Simple structure and light weight The glass curtain wall LED display adopts a hollow strip design. Compared with the traditional LED display box, its structure is more flexible. The box size can be customized according to the specific size of the glass to better fit the glass curtain wall and reduce load-bearing pressure. 3. Fast installation and easy maintenance The glass curtain wall P5*P10 Transparent LED Screen has a flexible structure, light weight and quick installation. When a certain LED light bar is damaged, only the single light bar needs to be replaced, and the entire module does not need to be replaced. The maintenance is done indoors with high efficiency and low cost. 4. Green energy saving, good heat dissipation performance The glass curtain wall led display does not need any auxiliary heat dissipation equipment because of its high transparency, no noise, low power consumption and other good performance, which can let the wind naturally dissipate heat. When it plays a video advertisement, the part of the content that is played is illuminated, and the rest is not illuminated. It saves more than 30% of energy than the conventional LED display. This playback method can also reduce energy consumption and reduce light pollution, responding to the national energy saving and emission reduction Call. 5. The LED Transparent Screen is convenient and quick to maintain: indoor maintenance is convenient and safe, saving manpower and material resources. 6. Save the cost of building lighting: If the LED Glass curtain wall display (LED Transparent Screen) is installed, a large part of the lighting lamps on the outer wall can be saved. At the same time, the LED Screen Glass is more absorbent, which can save costs and have advertising benefits. . 7. The LED Transparent Screen is energy-saving and environmentally friendly: its own power consumption is low, and the average power consumption is less than 280W/㎡, and it does not require traditional refrigeration systems and air conditioning heat dissipation. 8. Simple operation and strong controllability: It can be connected to a computer, a graphics card, and a remote transceiver through a network cable, or it can be controlled by a remote cluster wirelessly, and the display content can be changed at any time. 9. A wide range of applications: banks, shopping malls, theaters, commercial streets, chain stores, hotels, municipal public buildings, landmark buildings, office buildings, etc.

In addition to the quality of the product itself, overhaul and maintenance is also an important key to the lifespan of the transparent LED screen. It is reasonable for the transparent LED screen to have problems like any other product. What we can do is to better find out before the problem comes. For it, repair work should be done in advance as much as possible. What are the maintenance and inspection methods for LED transparent screens? 1. Resistance detection method We need to adjust the multimeter to the resistance range, first check the resistance value of a certain point of a normal circuit board to the ground, and then check the same point of another same circuit board to test whether the resistance value is different from the normal resistance value, if there is a difference, then Know the scope of the transparent screen problem, otherwise ignore it. 2. Voltage detection method Transparent screen voltage detection is to adjust the multimeter to the voltage range to detect the ground voltage at a certain point of the circuit that has a suspicious problem, and compare it with the previous one, so that the problem can be easily determined. 3. Short circuit detection method Set the multimeter to the short-circuit detection block, so that it can detect whether there is a short-circuit phenomenon. If a short circuit is found, it should be solved immediately. The short circuit is also the most common LED transparent screen module failure. In addition, short-circuit detection should be performed when the circuit is powered off to avoid damage to the multimeter. 4. Pressure drop detection method Adjust the multimeter to the diode voltage drop detection gear, because the transparent screen IC is composed of many single components, so when there is a current on one of its pins, there will be a voltage drop on the pins. Under normal circumstances, the voltage drop on the IC pins of the same model is similar.

First of all, we have to understand the main difference between Self Adhesive Smart Film and Intelligent Glass 1. Cost Smart Glass is a Non Adhesive Smart Film sandwiched between two layers of original glass, which is made into laminated glass through high pressure. The Selfadhesive Switchable Smart Film directly adopts an ITO film with adhesive to make a film that can be directly attached to the glass. In terms of cost, Self Adhesive Smart Film can save the cost of the original glass and all the costs of glass processing, and the price will be relatively lower. 2. Transportation PDLC Smart Glass is fragile, transportation has certain risks, and it is very heavy. Long-distance transportation must be packed in wooden boxes, and wooden box fees and freight are relatively high. The Intelligent Film can be directly rolled into a roller package, which is small in size, low in freight, and safer and more convenient to transport. 3. Installation The installation method ofPdlc Switchable Electrochromic Glassis basically the same as that of ordinary glass. Except that the wiring requires the guidance of the manufacturer, other projects can be completed in the same way as ordinary glass installation. However, the Self Adhesive Smart Film application process is more complicated. The glass surface is required to be clean and flat, and it requires skilled operators to pay attention to many points. 4. Security The Switchable Glass is in the form of glass, with high strength and hardness, and low man-made damage rate. The Selfadhesive Switchable Smart Film is relatively more expensive. It comes in the form of a film, so avoid being scratched by hard or sharp objects when using it. From this point of view, the Intelligent Glass and the Smart Film have their own merits. The cost of the Smart Glass is higher and the transportation is more troublesome, but the advantages are simple installation and high safety. On the contrary, although the cost of self-adhesive film is low, the installation is more troublesome, and the safety is not as good as that of PDLC Dimming Glass. So how to choose PDLC Smart Glass and Self Adhesive Film ? In fact, this problem is very simple. For some customers who have installed the glass and want to have a dimming effect, filming is a good way. However, the self-adhesive dimming film is recommended to be used in a relatively open environment to prevent people from uncovering the film because of curiosity and shorten the service life. The dimming glass does not have these concerns. Offices, hotels, partitions, doors and windows can all be used. It is still recommended that you choose according to your needs, compare things regardless of good or bad, it all depends on how to use

The application of dimming glass is more and more extensive, and people's understanding of dimming glass is getting deeper and deeper, and various factors that affect the visual effect of dimming glass have also been repeatedly mentioned. We often find that the same batch of glass or glass of the same specification has different effects in different application environments and different occasions, sometimes even very different. Is this a problem with the product? Absolutely not! So what factors cause What about the difference in the effect of dimming glass? 1. The position of the light Lighting is one of the important factors that cause differences in the effect of dimming glass. By changing the position of the light, we found that the light is far away from the glass, and the haze is very small visually; the light is close to the glass, and the haze is very large. 2. The angle of observation glass The same piece of glass, the same visual point, and the glass at different angles, the glass exhibits different effects. When people look at the glass and the line of sight is perpendicular to the glass, the visual effect is best; when the angle between the line of sight and the glass is less than 45 degrees or greater than 135 degrees, the sense of haze will increase. 3. The size of the space When people look at the objects behind through the glass, when the space behind the glass is large and the range is wide, the effect of the switch state of the dimming glass is perfect; when the space behind the glass is small and the range is close, dimming After the glass switch state is switched, the effect of the difference is not changed, but it will make people feel that the haze is relatively large. The above three aspects are the three main factors that affect the visual effect of dimming glass. I hope that designers will avoid these three factors when designing and using dimming glass to achieve a perfect visual effect.

https://www.youtube.com/watch?v=VAWwLuTke6w About Shenzhen YuGuang New Material Co.,Ltd PDLC Smart Glass and Smart Film According to the similarities and differences of control methods and principles, Smart Glass can switch between transparent and opaque state of glass by various methods such as electrical control, temperature control, light control, pressure control and so on. Due to various constraints, most of the PDLC Smart Glass mass-produced on the market are electronically controlled Smart Glass. The principle of electronically controlled Low Iron Switchable Smart Glass is relatively easy to understand. When the PDLC Film Power Supply of the electronically controlled product is turned off, the liquid crystal molecules of the electronically controlled Low Iron Switchable Smart Glass are irregularly dispersed to prevent the intrusion of light and make the Clear Switchable Smart Glass look opaque. ..

The smart film curtain uses a kind of fabric different from existing curtains. It is a kind of high-tech fabric made from flexible film through high-efficiency light induction, magnetron sputtering, and nano-material in-membrane lamination technology.

High Transparency Self Adhesive Smart Film INSTALLATION GUIDE Video Course: https://www.youtube.com/watch?v=XKEo5_x6EB0 1. Keep Extra Transparency Self Adhesive Switchable Film flat and straight at all times. Don`t let the FILM fold in any way, that will severely damage the Smart Film. 2. This FILM is a dry install application. High Transparency Self Adhesive Smart Film should be stick on glass only. Not on PC or plastic. DO NOT use water under any circumstances – self-adhesive can be installed using 99% isopropyl alcohol (medical alcohol) only. The alcohol should be sprayed lightly as an install aid only. DO NOT operate material until it is 100% dry! 3. Keep your working environment as clean and dust-free as possible for optimal results. 4. When measuring the outer dimensions, the Smart Film should be 2-3mm shorter than the glass area. 5. The Smart Film protective layer of the non-adhesive side should be kept on the installation until the installation process is completely finished. 6. You may wear nitrile gloves during installation; remove the adhesive side of the protective layer before starting the installation. 7. Handle the Smart FILM at the edges to avoid separating layers prematurely. 8. Use 65V AC power to the FILM with our transformer or other certified transformer. Each transformer covers different area depends on its Watt parameter. 9. The electrical contact strip ([Busbar") or the High Transparency Self Adhesive Smart Film edges should NEVER be in contact with the metal frame. www.ygsmartglass.com 10. Don`t pull together the busbar wire as it causes a shortcut! The busbar is easy to pull separate with the PDLC Switchalbe Film or glass! 11. After installation use only Neutral Silicon Sealant. A silicone with no ACID. Any other Silicone will damage the FILM 12. The Adhesive filmHigh Transparency Self Adhesive Smart Film should be used INDOOR only with no exposure to direct sun. Tools & Materials Required - Plastic scraper - Dust-free rubber roller - Small hand [squeegee" (tendon scraper) - Nitrile gloves - Lint-free cleaning cloths - Transparent glass cleaner (anti-static, anti-fog, dust-proof) - 99% Isopropyl alcohol - Neutral Silicon Sealant (Toshiba 381, Dow Corning 799) - Box cutter Also, very useful to get our installation kit: These two tools using for remove the bubble. The green one is hard and probably better to remove. It is up to installer. Installation Procedure Note: It is recommended not to open air condition during installation Part 1: Preparing the Smart FILM Step 1.1: Open the box and place the Smart Self-Adhesive Film ([FILM") on a clean, flat surface. Step 1.2: Ensure that the adhesive side is facing up. Do not remove the protective layer until you are instructed in this procedure to do so. The adhesive side is usually marked with a label or a red stamp. Note: When touching the self-adhesive side, the surface is little sticky, on the other side, no self-adhesive function, the surface is smooth. If there is some dirt on the surface, you can use alcohol to clean. Don`t worry, the self-adhesive function will be working well still. Step 1.3: Testing the FILM (by assessing whether it turns on and off). Connect wires into transformer. Part 2: Clean the Glass Surface Step 2.1: Using the liquid spray cleaner, spray the glass and use a cleaning roller to remove any dust and/or blemishes for optimal installation. Wipe the glass clean with a clean absorbent cloth. The surface of the glass should be completely smooth and immaculate. Repeat this step as necessary. Step 2.2: Using a soft, lint-free cloth, wipe the glass surface with isopropyl alcohol. Let this set-up last so that the alcohol may evaporate. Note: For clean the glass, alcohol is better than transparent glass cleaner but also could use glass cleaner spray. An experienced installer, use alcohol less since need lot of alcohol and alcohol is easy to evaporate. Normally one spray cleaner bottle could clean 8 sqm of glass. With Spray cleaner, you need to remove the water from glass liquid cleaner and then stick film on the glass. Note: High Transparency Self Adhesive Smart Film may be installed wet only by using 99% isopropyl alcohol only. Do not use water and do not soak. The alcohol should be sprayed lightly as an installation aid only. Do not continue to use the material until it is 100% dry! St2.3: Using a soft, lint-free cloth, wipe down the protective layer on the adhesive side of the FILM to remove any dust or contaminants, as seen below. Step 2.4: Very carefully, peel back the first 3-4 inches of the protective layer that is covering the adhesive side. Be sure that no dust falls onto the adhesive side during this step. Step 2.5: As seen in the photos below, align the self-adhesive FILM edge with the top edge of the glass. When the FILM is perfectly in position, run your finger along the top while pressing own on the FILM so that the applied self-adhesive will hold the FILM in position. Note: The glue on the High Transparency Self Adhesive Smart Film layer is not very strong on first touch. After alcohol is used to clean the glass firmly, and after one sticks the High Transparency Self Adhesive Smart Film onto the glass, the glue will then be very strong. Step 2.6: Pull away the protective layer slowly and allow the FILM to adhere to the glass under its own weight. Starting at the top, use the roller in a horizontal (side-to- side) motion, gradually moving down the glass to disperse any air bubbles. If air bubbles still persist, carefully lift the Smart Film, check if any dust particles have stuck to the adhesive side and remove them with adhesive tape if so, and let the FILM settle again without air bubbles. See photos below. You do not need to connect film to power supply to see bubble. Once installed ,if having bubble, it is easy to see it. Step 2.7: Repeat the process (starting with step 2.5) until the installation is free of any air bubbles. Step 2.8 (below) should be paid close attention to, should air bubbles be trapped on the edges of the FILM. Step 2.8: Use the soft-edge squeegee to remove any trapped air bubbles on the FILM`s edges. If any edges appear to be lifting slightly, the edges will relax once the protective layer is completely removed. Part 3: Testing and connecting to Power Step 3.1: Each High Transparency Self Adhesive Smart Film has busbar and a short wire on it. If you need additional wire, you may purchase regular wires from a local hardware store and solder to the existing wire. Step 3.2: Connecting to PDLC Film Power Supply. We have 230-65v AC and 115-65v AC controller types. Notes: In some remotes, there are no batteries included with the remote control. You may also install a wall switch or a remote switch wall. Step 3.3: Gathering several Smart Film to one transformer. Part 5: Finishing Touches Step 5.1: Use Neutral Silicone Sealant (No Acid) along the Extra Transparency Self Adhesive Switchable Film edges. First, stick the tape on the edge of the PDLC Smart Film (2mm shorter than the edge of the Extra Transparency Self Adhesive Switchable Film). Then, apply the silicone glue on the edge of the PDLC Switchable Film and use the small hand squeegee to ensure the silicone glue is applied equally smoothly everywhere. Finally, remove the tape from the Extra Transparency Self Adhesive Switchable Film. Note: They are a many color to every Silicone brand. We recommend to use Translucent Silicone. Note: If you do not use Neutral Silicone, any damage to the Extra Transparency Self Adhesive Switchable Film (such as delamination) is not under our product warranty. Then use PDLC Smart Glass silicone glue to seal it, as shown above. Finally, make silicone glue smooth and clean. Step 5.2: Let PDLC Smart Glass silicone glue dry for a minimum of one day. Congratulations-your installation is now complete! Cleaning Please clean Smart FILM with spray alcohol or a wet dust-free paper/high-quality towel, then clean and wipe glass. Troubleshooting What if the window was not clean well before we stick the PDLCSwitchable Film? Normally you should first spend more than one hour, even two- three hours to clean glass. Then sticking is very easy and there is no reason to take it out. After taking out the Extra Transparency Self Adhesive Switchable Film, the glue will be a bit weaker and the film will lose a bit its toughness, especially with the big Smart Film. The film was designed for one stick only. Additional Note Normally, it is not best to use scissors to cut the PDLC Smart FILM. The company`s professional cutting machine should cut the smart FILM for best results. If one must use normal scissors to re-size the smart Film, please use professional tailor`s scissors, as pictured below. However, even if one uses professional tailor`s scissors, our company still cannot 100% guarantee that the PDLC Switchable Film application process will be problem-free and optimal. Cutting the FILM by oneself is not covered under our product guarantee. Our suggestion, that is covered under our guarantee, is that one arranges to cut the Extra Transparency Self Adhesive Switchable Film using a professional cutting machine.

The plastic and liquid crystal include a liquid crystal ball and a polymer, and the liquid molecule director is approximately parallel to the glass substrate , the polymer is surrounded by the liquid crystal micro droplet, the refractive index of the polymer is np , which is similar to the refractive index of the glass. Approximately 1.5 , an is isotropic substance, the unusual refractive index and the ordinary refractive index of liquid crystals are ne and n, respectively. When the vertically incident visible light passes through the glass and transparent ITO film ,it enters the liquid crystal sphere and the polymer interface, due to ne is not equal to ne , So scattering occurs and the PDLC Smart Film is atomized. (2) PDLC Switchable Film When the external electric field is applied, the electric field is formed between the two transparent ITO films, and the liquid crystal molecules are arranged in the direction of the electric field. When the vertically incident visible light passes through the glass and the transparent ITO film, it is incident to the interface between the liquid crystal sphere and the polymer. Because the no direction is perpendicular to the direction of light propagation and no is equal to np, the glass is transparent. (3) Extra Transparency Self Adhesive Switchable Film haze The main indicator of the advantages and disadvantages of PDLC Switchable Film optical performance is transparency. In fact, it is the haze. The smaller thaze when energized, the better haze when the power is cut off. When the external electric field is applied, the light is perpendicular to the direction of the transparent conductive film. PDLC Film Power Supply When incident, although nLC is approximately equal to no, However, due to the difference between the nP and no values, scattering still occurs at the interface between liquid crystal droplets and polymers. This is the main reason for the haze. (4) View angle When the ITO film is power on, Angle between incident light and the vertical direction of the electric control film is not zero(Called the view angle [a") The direction of light propagation in the Smart Film is not parallel to the liquid crystal molecule pointing vector, as shown in the figure:At the interface between liquid crystal droplets and polymers, the component of light vibrating along the NE direction is scattered, and the larger a is, the more scattered, so the mist increases with the increase of the angle of view, which is the characteristic of the photoelectric effect of liquid crystal.
