For our transparent lcd display, it is like the normal lcd monitor, but we have special technology, when you play the white color on the video or pictures, the screen is transparent;

Transparent OLED Displays are a stunning new development in digital signage and display technology. These transparent display screens are used to communicate dynamic or interactive content via a transparent surface allowing viewers to see what is shown on the screen whilst still being able to see through the display. This solution allows designers creative ways to display content whilst curating a futuristic ‘Minority Report’ type effect.

OLED stands for Organic Light Emitting Diode, a technology that eliminates the need for a backlight or enclosure. Standard Transparent LCD screens require backlighting to create a visible image, whereas Transparent OLED screens are made up of millions of pixels that each emit their own individual light. This opens up a whole new field of creativity in digital signage that even transparent LCD screens cannot offer. Unlike Transparent LCD screens, Transparent OLED screens display black content as transparent instead of white content. This puts a different spin on the merchandising process, offering new ways to communicate in an imaginative way with your audience.

Transparent OLED Screens are also available with Infrared or PCAP interactive touch overlays to create immersive touch screen displays. The benefits oftouch screen technologyare well documented, and when combined with Transparent OLED displays, you are sure to see customers interacting with content in ways you have not seen before.

Transparent OLED Displays are available in 55” screen sizes with Video Wall options available to create large format displays. Both options are also available as a Transparent Touch Screen providing multi-touch functionality.

Transparent OLED Displays are available in several options with or without touch or alternatively, as a Transparent OLEDVideo Wallwhere the displays can be joined to create a large-format screen, providing a stunning visual display with an impact! Get in touch with our sales team today for a quote.

No, Transparent OLEDs do not require a backlight, these screens are made up of millions of self-lit pixels that come together to create an image. This gives you greater control over the brightness and lighting of the screen depending on your environment.

Transparent OLED Screens are HD displays that despite being see-through in appearance when turned off and on, can produce an image that covers the whole screen offering a crisp resolution perfect for up-close viewing applications. These are commonly used for POS displays, demonstrations & exhibitions and in other hands-on environments.

Transparent LED Displays on the other hand are designed for large format displays, offering high brightness that is unphased by broad daylight, with the gaps between the LEDs providing transparency. These are usually used in larger window displays that are restricted for space or across large areas of glass facades in corporate buildings or offices, as they offer the power of a standard LED screen with the benefit of still being able to see through them.

As standard Transparent OLED Screens are currently only available in a 55” screen size, however, they can be joined together to create Transparent OLED Video Walls. Whilst these can be joined in any 2 x N format, the most popular solution is using 4 OLED screens together to create an almost two and a half meter tall transparent video wall.

We can also grant our Transparent OLED Displays interactivity by combining them with a touch frame, creating a holographic touch screen that can be used by multiple users at any one time. We also manufacture custom housings for our Transparent OLEDs which can be custom designed to suit your requirements, with options for custom branding and logos.

Transparent OLEDs are made up of pixels that emit their own light whereas Transparent LCD’s need a backlight to produce an image, this is why Transparent LCD’s require full housing solutions to create the best possible image. Another key difference is that when turned off, Transparent OLED screens remain transparent, unlike Transparent LCD’s which are not see-through when switched off, simply displaying a black screen.

Available in sizes from 21.5" to 98“, the HYPEBOX is based on a transparent display, which enables the viewer to see the real product inside of the showcase while digital content is shown on the see-through LCD screen. In this way, products can be put in context with digital media like photos, videos, text or any other kind of content. In addition, the HYPEBOX is equipped with a state-of-the multitouch screen which basically acts as an interactive layer on top of the display surface.

Important technical improvements of LCD, such as LED backlighting and wide viewing Angle, are directly related to LCD. And account for an LCD display 80% of the cost of the LCD panel, enough to show that the LCD panel is the core part of the entire display, the quality of the LCD panel, can be said to directly determine the quality of an LCD display.

The production of civil LCD displays is just an assembly process. The LCD panel, the main control circuit, shell, and other parts of the main assembly, basically will not have too complex technical problems.

Does this mean that LCDS are low-tech products? In fact, it is not. The production and manufacturing process of the LCD panels is very complicated, requiring at least 300 process processes. The whole process needs to be carried out in a dust-free environment and with precise technology.

The general structure of the LCD panel is not very complex, now the structure of the LCD panel is divided into two parts: the LCD panel and the backlight system.

Due to the LCD does not shine, so you need to use another light source to illuminate, the function of the backlight system is to this, but currently used CCFL lamp or LED backlight, don’t have the characteristics of the surface light source, so you need to guide plate, spreadsheet components, such as linear or point sources of light evenly across the surface, in order to make the entire LCD panel on the differences of luminous intensity is the same, but it is very difficult, to achieve the ideal state can be to try to reduce brightness non-uniformity, the backlight system has a lot to the test of design and workmanship.

In addition, there is a driving IC and printed circuit board beside the LCD panel, which is mainly used to control the rotation of LCD molecules in the LCD panel and the transmission of display signals. The LCD plate is thin and translucent without electricity. It is roughly shaped like a sandwich, with an LCD sandwiched between a layer of TFT glass and a layer of colored filters.

LCD with light refraction properties of solid crystals, with fluid flow characteristics at the same time, under the drive of the electrode, can be arranged in a way that, in accordance with the master want to control the strength of the light through, and then on the color filter, through the red, green, blue three colors of each pixel toning, eventually get the full-screen image.

According to the functional division, the LCD panel can be divided into the LCD panel and the backlight system. However, to produce an LCD panel, it needs to go through three complicated processes, namely, the manufacturing process of the front segment Array,the manufacturing process of the middle segment Cell, and the assembly of the rear segment module. Today we will be here, for you in detail to introduce the production of the LCD panel manufacturing process.

The manufacturing process of the LCD panel Array is mainly composed of four parts: film, yellow light, etch and peel film. If we just look at it in this way, many netizens do not understand the specific meaning of these four steps and why they do so.

First of all, the motion and arrangement of LCD molecules need electrons to drive them. Therefore, on the TFT glass, the carrier of LCD, there must be conductive parts to control the motion of LCD. In this case, we use ITO (Indium Tin Oxide) to do this.ITO is transparent and also acts as a thin-film conductive crystal so that it doesn’t block the backlight.

The different arrangement of LCD molecules and the rapid motion change can ensure that each pixel displays the corresponding color accurately and the image changes accurately and quickly, which requires the precision of LCD molecule control.ITO film needs special treatment, just like printing the circuit on the PCB board, drawing the conductive circuit on the whole LCD board.

This completes the previous Array process. It is not difficult to see from the whole process that ITO film is deposited, photoresist coated, exposed, developed, and etched on TFT glass, and finally, ITO electrode pattern designed in the early stage is formed on TFT glass to control the movement of LCD molecules on the glass. The general steps of the whole production process are not complicated, but the technical details and precautions are very complicated, so we will not introduce them here. Interested friends can consult relevant materials by themselves.

The glass that the LCD board uses makes a craft also very exquisite. (The manufacturing process flow of the LCD display screen)At present, the world’s largest LCD panel glass, mainly by the United States Corning, Japan Asahi glass manufacturers, located in the upstream of the production of LCD panel, these manufacturers have mastered the glass production technology patents. A few months ago, the earthquake caused a corning glass furnace shutdown incident, which has caused a certain impact on the LCD panel industry, you can see its position in the industry.

As mentioned earlier, the LCD panel is structured like a sandwich, with an LCD sandwiched between the lower TFT glass and the upper color filter. The terminal Cell process in LCD panel manufacturing involves the TFT glass being glued to the top and bottom of a colored filter, but this is not a simple bonding process that requires a lot of technical detail.

As you can see from the figure above, the glass is divided into 6 pieces of the same size. In other words, the LCD made from this glass is finally cut into 6 pieces, and the size of each piece is the final size. When the glass is cast, the specifications and sizes of each glass have been designed in advance.

Directional friction:Flannelette material is used to rub the surface of the layer in a specific direction so that the LCD molecules can be arranged along the friction direction of the aligned layer in the future to ensure the consistency of the arrangement of LCD molecules. After the alignment friction, there will be some contaminants such as flannelette thread, which need to be washed away through a special cleaning process.

After the TFT glass substrate is cleaned, a sealant coating is applied to allow the TFT glass substrate to be bonded to the color filter and to prevent LCD outflow.

Finally, the conductive adhesive is applied to the frame in the bonding direction of the glass of the color filter to ensure that external electrons can flow into the LCD layer. Then, according to the bonding mark on the TFT glass substrate and the color filter, two pieces of glass are bonded together, and the bonding material is solidified at high temperatures to make the upper and lower glasses fit statically.

Color filters are very important components of LCD panels. Manufacturers of color filters, like glass substrate manufacturers, are upstream of LCD panel manufacturers. Their oversupply or undersupply can directly affect the production schedule of LCD panels and indirectly affect the end market.

As can be seen from the above figure, each LCD panel is left with two edges after cutting. What is it used for? You can find the answer in the later module process

Finally, a polarizer is placed on both sides of each LCD substrate, with the horizontal polarizer facing outwards and the vertical polarizer facing inwards.

When making LCD panel, must up and down each use one, and presents the alternating direction, when has the electric field and does not have the electric field, causes the light to produce the phase difference and to present the light and dark state, uses in the display subtitle or the pattern.

The rear Module manufacturing process is mainly the integration of the drive IC pressing of the LCD substrate and the printed circuit board. This part can transmit the display signal received from the main control circuit to the drive IC to drive the LCD molecules to rotate and display the image. In addition, the backlight part will be integrated with the LCD substrate at this stage, and the complete LCD panel is completed.

Firstly, the heteroconductive adhesive is pressed on the two edges, which allows external electrons to enter the LCD substrate layer and acts as a bridge for electronic transmission

Next is the drive IC press. The main function of the drive IC is to output the required voltage to each pixel and control the degree of torsion of the LCD molecules. The drive IC is divided into two types. The source drive IC located in the X-axis is responsible for the input of data. It is characterized by high frequency and has an image function. The gate drive IC located in the Y-axis is responsible for the degree and speed of torsion of LCD molecules, which directly affects the response time of the LCD display. However, there are already many LCD panels that only have driving IC in the X-axis direction, perhaps because the Y-axis drive IC function has been integrated and simplified.

The press of the flexible circuit board can transmit data signals and act as the bridge between the external printed circuit and LCD. It can be bent and thus becomes a flexible or flexible circuit board

The manufacturing process of the LCD substrate still has a lot of details and matters needing attention, for example, rinse with clean, dry, dry, dry, ultrasonic cleaning, exposure, development and so on and so on, all have very strict technical details and requirements, so as to produce qualified eyes panel, interested friends can consult relevant technical information by a search engine.

LCD (LC) is a kind of LCD, which has the properties of light transmission and refraction of solid Crystal, as well as the flow property of Liquid. It is because of this property that it will be applied to the display field.

However, LCD does not emit light autonomously, so the display equipment using LCD as the display medium needs to be equipped with another backlight system.

First, a backplate is needed as the carrier of the light source. The common light source for LCD display equipment is CCFL cold cathode backlight, but it has started to switch to an LED backlight, but either one needs a backplate as the carrier.

CCFL backlight has been with LCD for a long time. Compared with LED backlight, CCFL backlight has many defects. However, it has gradually evolved to save 50% of the lamp and enhance the transmittance of the LCD panel, so as to achieve the purpose of energy-saving.

With the rapid development of LED in the field of lighting, the cost has been greatly reduced.LCD panels have also started to use LED as the backlight on a large scale. Currently, in order to control costs, an LED backlight is placed on the side rather than on the backplate, which can reduce the number of LED grains.

On the transparent diffuser plate, point-like printing can block part of the light. The LED backlight on the side drives the light from the side of the diffuser plate, and the light reflects and refracts back and forth in the diffuser plate, distributing the light evenly to the whole surface. Point-like printing blocks part of the light, screening the light evenly like a sieve.

At the top of the diffusion plate, there will be 3~4 diffuser pieces, constantly uniform light to the whole surface, improve the uniformity of light, which is directly related to the LCD panel display effect. Professional LCD in order to better control the brightness uniformity of the screen, panel procurement, the later backlight control circuit, will make great efforts to ensure the quality of the panel.

Since the LCD substrate and the backlight system are not fixed by bonding, a metal or rubber frame is needed to be added to the outer layer to fix the LCD substrate and the backlight system.

After the period of the Module, the process is completed in LCM (LCDModule) factory, the core of this part of the basic does not involve the use of LCD manufacturing technology, mainly is some assembly work, so some machine panel factories such as chi mei, Korea department such as Samsung panel factory, all set with LCM factories in mainland China, Duan Mo group after the LCD panel assembly, so that we can convenient mainland area each big monitor procurement contract with LCD TV manufacturers, can reduce the human in the whole manufacturing and transportation costs.

However, neither Taiwan nor Korea has any intention to set up factories in mainland China for the LCD panel front and middle manufacturing process involving core technologies. Therefore, there is still a long way to go for China to have its own LCD panel industry.

Relying on continuous innovation, we are working on high grade of transparent LCD and relevant display technology to meet customer requirements by providing application product and industrial solutions for clients in various fields,such as trade shows, advertisement, game, retail and home appliance, InnoGlass has already become a leading brand and pioneer of Transparent LCD display field.

For our transparent lcd display, it is like the normal lcd monitor, but we have special technology, when you play the white color on the video or pictures, the screen is transparent;

The transparent LCD is a kind of LCD screen that you can see through it when it’s working. You can read the information on the screen and see what’s behind it at the same time. Such a screen is not a new technology. It’s a branch of the traditional screen which has been more than 20 years.

The biggest difference between a transparent LCD and with traditional LCD screen is its light transmittance is higher. In theory, the higher the light transmittance, the better the effect that you can see through the screen.

The transparent LCD is the core part of the transparent monitor. It can not emit light by itself, so the backlight is essential when it’s working. If you don’t like the backlight, then what we recommend is the transparent OLED.

The transparent LCD is widely used in lots of applications, for example, video walls, vending machines, display boxes, and others. It usually is used with a touch screen. Such LCD with touch screen is interactive and interesting.

The transparent LCD  is made by a daily used liquid crystal display screen. Such a product is an LCD panel without an LED backlight. It has a proper name which is called open cell LCD panel. It doesn’t have a frame and the thickness is just about 1.4mm.

The transparent LCD has many custom features, such as size, resolution, and so on. If you want to use the such product normally, there are also some details that you need to pay attention to.

Plenty of clients buy a such product from us, but they can not use them or sell it to their customers right now when they get them. That’s because the transparent LCD is just a semi-finished product. Most of the clients need to install it on their machines.

GECEY can provide the full sizes of the transparent LCD. Please don’t worry about there is not having the proper size for your application. The most commonly used resolution of such a screen is 1920 x 1080 (FHD). If you need the 4K resolution( 3840 x 2160 ), please feel free to contact us first.

The transparent LCD has a professional name which is called open cell panel. You can see its appearance in the picture on the left below. It looks like a black panel with a driver board. The picture on the right below is its internal structure. We can see that the structure is complex. It contains two polarizers, two glass substrates, liquid crystals, and so on.

The polarizer is made of a kind of material that looks like plastic. It has a direction. It just allows the light in which the waves are in the same direction to pass through. The directions of the two polarizers are perpendicular to each other. The polarizer is like a light filter. It’s used to improve the color and definition. If there is a polarizer, you can see nothing from the screen.

The reason why we introduce the polarizer is that it can greatly influence the light transmittance and brightness of the screen. For the manufacturer, we usually change the polarizer to improve the light transmittance. The production process requires special workplaces, skilled workers, special materials, and special care. This is because the transparent LCD is very fragile and easy to be damaged.

Light transmittance is a very important parameter for transparent LCD. The higher the transmittance, the higher the brightness, and the more you can see the product behind the screen.

How much is the light transmittance of the common screen? The picture below is the SPEC of the AUO 32” open cell panel the model is T320HVN05.6 CELL. From the picture, we can see it’s 6.5%. If you check the SPEC of LCD screens which are from super manufacturers, such as Samsung, LG, AUO, and so on, you can find the transmittance of them is around 6.5%.

However, 6.5% is not enough for the transparent LCD display. So it’s essential to change the polarizer. Some special materials and polarizers are needed. The process is not easy, especially the big sizes. If the operation is wrong, the screen will be damaged.

The super manufacturers of open-cell panels will not do this for you. The process is finished by the manufacturer of a transparent LCD. So, finding a professional manufacturer is very necessary, if you want to buy some.

LED backlight: LCD can not emit light by itself. So it needs the backlight so that you can see through when it’s working. For details, please see the rest content.

Controller: Same with the common LCD panel, it needs the controller to work. The controller receives the signal from the computer or U disk and sends it to the panel, then the panel can display the letters, pictures, and others.

Glass: The glass is used to protect the transparent LCD. Although glass is not essential, it’s used in most applications. The LCD screen is glued on one surface of the glass.

Frame: The frame is essential. It’s used to hold the LCD screen, glass, backlight, control board, and other parts. Some clients need their supplier to make the frame for them, some others can make it by themselves.

The most commonly used backlight system is made of several LED strips with white light directly. The color temperature is about 6000K( pure white). The LED strips are placed on the back of the screen. They are usually located at the top or bottom or on the left and right sides of the space.

The LED strips are driven by a small controller so that they can work in sync with the transparent LCD. The LED backlight panel can also be used to make the backlight system. The key points are the light of the space should be bright and even enough.

Second, the transparent LCD is not suitable for playing pictures or videos with complex colors. The large area of complex colors will affect your to see through the screen. It would be hard to see the products behind the screen clearly. Please keep most areas of the LCD to play white color.

When the screen displays white, it’s the most perfect condition to watch the product behind it. So, when you make the pictures or videos, please keep the background to be white. Just use the transparent LCD to play the introductions or videos with simple color.

First, the transparent LCD can not emit light by itself. Second, the space around the screen can be divided into two parts: the dark area which is in front of the screen, and the bright area with backlight which is behind the screen. People can see through from the dark area to the bright area, but they can’t see through from the opposite direction.

Most of the transparent LCDs we exported are frameless. The clients have the frame and can install the product by themselves. If you don’t have the frame, then we can also make it for you. Most of the frames are made of aluminum and iron plate. The aluminum frames are light, strong, and easy to be produced. The frames have many custom features, such as sizes, thicknesses, and so on.

Plenty of clients want to use the transparent LCD to modify their products and they just need only one piece. For example, the LCD side panel PC case is very popular. There is a transparent screen on one side of the PC case. You can see the inside of the PC and play the videos you love at the same time.

Such a case for gaming looks very amazing so lots of people want to have one. However, it’s hard for them to find a supplier to buy just one piece of transparent LCD and it would take a long time to get one. So, they want to DIY by themselves.

There are some guides online that teach people to use a common monitor to DIY a transparent LCD. For example, use the screen of a second computer monitor to make one. The simple process is to remove most parts of the LCD panel of the monitor, leaving only the LCD screen( open cell), then install some LED strips and the open cell on their PC case.

Does it work? Yes, but there are many problems in the DIY process. First of all, you need to be very careful in the DIY process. The LCD open-cell glass is very fragile. There are several flexible PCB cables at the bottom of the screen. If either of them is damaged, then the screen can not work normally.

Second, the transmittance of the screen that you DIY is much lower than the professional transparent LCD. So the final effect is not as good as you think. There are also some other problems, for example, you need to put one tempered glass to protect the LCD screen. We recommend buying one transparent LCD directly.

A see-through display or transparent display is an electronic display that allows the user to see what is shown on the screen while still being able to see through it. The main applications of this type of display are in head-up displays, augmented reality systems, digital signage, and general large-scale spatial light modulation. They should be distinguished from image-combination systems which achieve visually similar effects by optically combining multiple images in the field of view. Transparent displays embed the active matrix of the display in the field of view, which generally allows them to be more compact than combination-based systems.

Broadly, there are two types of underlying transparent display technology, absorptive (chiefly LCDs) and emissive (chiefly electroluminescent, including LEDs and "high-field" emitters). Absorptive devices work by selectively reducing the intensity of the light passing through the display, while emissive devices selectively add to the light passing through the display. Some display systems combine both absorptive and emissive devices to overcome the limitations inherent to either one. Emissive display technologies achieve partial transparency either by interspersing invisibly small opaque emitter elements with transparent areas or by being partially transparent.

The development of practical transparent displays accelerated rapidly around the end of first decade of the 21st century. An early commercial transparent display was the Sony Ericsson Xperia Pureness released in 2009, although it did not succeed in the market due to the screen not being visible outside or in brightly lit rooms.

Samsung released their first transparent LCD in late 2011, and Planar published a report on a prototype electroluminescent transparent display in 2012.LCD technology. LG also uses OLED technology. Electroluminescent Displays enabled by Atomic layer deposition (ALD). This display technology was used by Valtra in 2017 to develop its SmartGlassSamsung and Planar Systems previously made transparent OLED displays but discontinued them in 2016.

There are two major see-through display technologies, LCD and LED. The LED technology is older and emitted a red color, OLED is newer than both using an organic substance. though OLED see-through displays are becoming more widely available. Both technologies are largely derivative from conventional display systems, but in see-through displays, the difference between the absorptive nature of the LCD and emissive nature of the OLED gives them very different visual appearances. LCD systems impose a pattern of shading and colours on the background seen through the display, while OLED systems impose a glowing image pattern on the background. TASEL displays are essentially transparent thin-film Electroluminescent Displays with transparent electrodes.

An LCD panel can be made "see-through" without applied voltage when a twisted nematic LCD is fitted with crossed polarizers. Conventional LCDs have relatively low transmission efficiency due to the use of polarizers so that they tend to appear somewhat dim against natural light. Unlike LED see-through displays, LCD see-throughs do not produce their own light but only modulate incoming light. LCDs intended specifically for see-through displays are usually designed to have improved transmission efficiency. Small scale see-through LCDs have been commercially available for some time, but only recently have vendors begun to offer units with sizes comparable to LCD televisions and displays. Samsung released a specifically see-through designed 22-inch panel in 2011. As of 2016, they were being produced by Samsung, LG, and MMT, with a number of vendors offering products based on OEM systems from these manufacturers. An alternative approach to commercializing this technology is to offer conventional back-lit display systems without the backlight system. LCD displays often also require removing a diffuser layer to adapt them for use as transparent displays.

The key limitation to see-through LCD efficiency is its linear polarizing filters. An ideal linear polarizer absorbs half of the incoming unpolarized light. In LCDs, light has to pass two linear polarizers, either in the crossed or parallel-aligned configuration.

LED screens to have two layers of glass on both sides of a set of addressable LEDs. Both inorganic and organic (OLED) LEDs have been used for this purpose. The more flexible (literally and figuratively) OLEDs have generated more interest for this application, though as of July 2016 the only commercial manufacturer Samsung announced that the product would be discontinued.LCDs in that OLEDs produce their own light, which produces a markedly different visual effect with a see-through display. The narrow gap between the pixels of the screen as well as the clear cathodes within allows the screens to be transparent. These types of the screen have been notoriously difficult and expensive to produce in the past, but are now becoming more common as the method of manufacturing them is advancing.

Unlike transparent LCDs and OLEDs that requires integrated electronic modules to process visual signals or emit their own light, a passive transparent display uses a projector as the external light source to project images and videos onto a transparent medium embedded with resonance nanoparticles that selectively scatter the projected light.

See-through screens are an emerging market that has several potential uses. Cell phones, tablets and other devices are starting to use this technology. It has an appealing appearance but more importantly it is also effective for augmented reality applications. The device can add its own twist to what is behind the screen. For example, if you look through a tablet with a see-through display at a street, the device could overlay the name of the street onto the screen. It could be similar to Google street view, except in real-time. For example, Google Translate has a feature that allows the user to point the camera at a sign or writing in another language and it automatically displays the same view, but with the writing in the language of your choosing. This could be possible with see-through displays as well.

A device using a transparent display will have much higher resolution and will display much more realistic augmented reality than video augmented reality, which takes video, adds its own supplement to it, and then displays that onto the screen.Microsoft HoloLens is an application of this idea.

A liquid crystal display (LCD) has liquid crystal material sandwiched between two sheets of glass. Without any voltage applied between transparent electrodes, liquid crystal molecules are aligned in parallel with the glass surface. When voltage is applied, they change their direction and they turn vertical to the glass surface. They vary in optical characteristics, depending on their orientation. Therefore, the quantity of light transmission can be controlled by combining the motion of liquid crystal molecules and the direction of polarization of two polarizing plates attached to the both outer sides of the glass sheets. LCDs utilize these characteristics to display images.

An LCD consists of many pixels. A pixel consists of three sub-pixels (Red/Green/Blue, RGB). In the case of Full-HD resolution, which is widely used for smartphones, there are more than six million (1,080 x 1,920 x 3 = 6,220,800) sub-pixels. To activate these millions of sub-pixels a TFT is required in each sub-pixel. TFT is an abbreviation for "Thin Film Transistor". A TFT is a kind of semiconductor device. It serves as a control valve to provide an appropriate voltage onto liquid crystals for individual sub-pixels. A TFT LCD has a liquid crystal layer between a glass substrate formed with TFTs and transparent pixel electrodes and another glass substrate with a color filter (RGB) and transparent counter electrodes. In addition, polarizers are placed on the outer side of each glass substrate and a backlight source on the back side. A change in voltage applied to liquid crystals changes the transmittance of the panel including the two polarizing plates, and thus changes the quantity of light that passes from the backlight to the front surface of the display. This principle allows the TFT LCD to produce full-color images.
