The price making it vary depending on the type of customer. However, depending on the type and material of the film, it also depends on the size and the material used. reflective film polycarbonate is one of the most commonly used materials. It is also called reflective film polymer, which is a reflective film from polyethylene terephthalate (PET) film and reflective film polycarbonate) are the two common types of reflective film on the market.

reflect film is different, and each one is used differently. On the other hand, the film is made from polyethylene, aethylene film, and is one of the most common types.

Although reflective film is different, it is important to remember the quality of the reflective part of the film. When it comes to reflective film, lcd is is of different quality. However, the color usually shades with different shades and colors.

When choosing reflective film, the color, size, and design of the reflective film is different. It ’ s important to remember that the reflective film, in color, and light are create different colors. The reflective glass lcd varieties utilize the reflective film color, light, and create different effects even on the user.s a reflective glass lcd display can be reflected in a way that changes the color of the film, as it changes in the light.

Application: Suitable for reflective clothing, reflective shirts, reflective fashion shirts, reflective vest, glow in the dark tape, security vest, reflective triangles, reflective jacket

Reflective material categories into reflective sheeting and reflective fabric, reflective fabric tape apply for personal safety and fashion application. Reflective fabric always shows in our daily life as we all know, such as reflective clothing, safety vest, reflective hat, reflective bag, etc. And reflective material has 4 points features as below:

Reflective fabric is one of the essential materials for personal safety, now days, this reflective material also gets more popular in the fashion industry. Reflective tape is composed of lens glass beads with different backing fabric, the most common materials are polyester, T/C, spandex. For fashion garments, we also supply reflective heat transfer vinyl, rainbow reflective fabric, and reflective printing fabric.

In order to match the characteristics and uses of other products, reflective material is manufactured as different reflectivity, backing fabric, washing cycles reflective tape for daily necessaries application, usually divide into reflective cloth, reflective thermosensitive film, reflective yarn, reflective logo and other products for various style of application.

Reflective fabric generally requires to pass the washing cycles, normally we are talking about domestic washing cycles for most of reflective fabric. Domestic washing ISO 6330, 6n, at 60℃ for 25 washing cycles, the reflective fabric remains the minimum coefficient of retro-reflection after domestic washing cycles, rainfall, and cold temperature. Moreover, some specific reflective fabric is required to qualify for industrial wash, these reflective materials are applied for reflective garments for oil, petrol, or mining application.

Reflective material tape can reflect original light under the lighting of headlamp light or road light. I think many drivers know that when you are driving on the highway. As the name suggests, reflectivity is one of the most important characteristics of reflective materials.

It is precisely because of the reflective nature that reflective materials can provide the most effective and reliable personal safety guarantee at night or in poor sight environments.

Reflective material usually has better wide-angle, so that reflective fabric also can keep a good reflective effect, reflect light directly even there is a wide-angle between reflective film and lighting.

This wide-angle feature of reflective fabric material is applied to the production of reflective work clothes like uniforms of traffic police, which can well improve personal safety in the dark situation, such as roadway, construction work zone, etc.

Generally speaking, the service life of reflective fabric is different from reflective sheeting, reflective fabric applies for garments, vests, shoes, hats, etc, thus washing cycles for either domestic wash or industrial wash is more essential. For example, XW2606-2B polyester reflective fabric tape has 25 domestic washing cycles, whereas, XW2720-6 TC reflective fabric meets 100 domestic washing cycles.

Of course, the raw reflective material using and selling price of reflective tape is different due to the different requirements of reflection value and service life. For example, the aramid flame resistant reflective tape has a feature of flame and heat resistant, this is important material for fireman garments. In a word, you can choose a different standards of reflective tape according to your needs.

Reflective fabric is 50cm height a roll, you can package them in a hard carton in order, reflective fabric rolls are easy to package and storage. When you order reflective fabric from XW Reflective manufacturer or another reflective material supplier, they will package your reflective fabric products well, therefore, you don’t worry more about extrusion deformation.

Reflective fabric has different backing fabric materials, such as polyester, T/C, aramid, BPU, PES, etc. different materials have different processes. For example, elastic reflective tape XW2606-8XW with backing material polyester and spandex, the process is sewing on different garments; whereas, reflective heat transfer vinyl XW8006, it is BPU backing, thus the process is hot pressing. All reflective fabric can apply for reflective clothing, reflective shirts, reflective fashion shirts, reflective vest, glow in the dark tape, security vest, reflective triangles, reflective jacket

We strongly recommend handling the reflective fabric with protected gloves and keep them in the environment of below 26.7℃ and 30 -50 % relative humidity.

XW701-B white PVC prismatic tape is mainly used on cost-saving type high visibility clothing, suitable for sportswear, outdoor wear, life safety vest, reflective bags, reflective shoes, etc., which can enhance the visibility for wearers even in a wet or poor light environment.

Moreover, PVC reflective fabric composes of micro-prismatic vinyl film and back seals with white PVC sheeting, which shows as white at daytime, can reflect light directly to the original light source, so that this PVC prismatic reflective fabric is suitable for safety clothing, of course, the reflective tape also popular for fashion clothing.

Reflective fabric for clothing is made of substrate, composite glue, reflective layer, and glass beads, widely used for outdoor safety reflective products, such as safety equipment, safety uniforms, work clothing, sanitation clothing. and these reflective safety products’ application benefits from the reflective effect of the reflective fabric tape.

You need a display that can be seen by everyone, everywhere. This is why E3 Displays uses a combination of technologies such as well designed LED backlight rails, LED component selection, optical bonding, and film enhancements to reduce light reflections and maintain or increase contrast for higher efficiency. The results are a display that is viewable in all environments and will create versatility and reliability enabling you and your team to focus on what you do best, rather than the tools at hand.

E3 Displays can enhance your solution by adding filters with AR/AG/AS to combat reflected light and finger marks via coated glass material or film lamination to displays. Your display solution can also be optically bonded, which limits layer reflection with the addition of AR/AG/AS to glass/touch.

As the light reflects off the surface of your display screen, it is scattered at different angles, which reduces the clarity of the image. E3 provides Anti-Glare solutions that ensure the consumer will not see the bright glare of any reflected light source.

AF/AS reduces the ability of the cover lens retaining oils from your finger. Thus providing you with a more crystal clear display without all of the fingerprints and smudge marks.

To achieve the best viewing experience for your display in outdoor, high ambient light applications, high-brightness display solutions are a must. Where brightness enhancement, anti-reflective and anti-glare films passively improve a display visibility in these scenarios, active high brightness display enhancements result in best screen visibility.

E3 can add high efficiency LED backlight rails to low luminance displays. This product line provides a simpler, less costly option of replacing lamps and power sources in an existing LCD panel.

Display backlighting can also be replaced to fit a power budget, typically a concern in mobile battery power applications. An E3backlight system can often maintain a level of brightness at a much lower power level than the factory backlight system.

E3 Displays can add frontlights or backlights to reflective type displays to read in dark environments. These innovative lightweight two-glass designed MLCD, paired with an integrated driver provides an exceptionally thin module profile.

These solutions have color TFT display models that feature Night Vision Imaging System (NVIS)-compliant LED backlighting system, which allows excellent readability.

Our E3 team has expertise in every type of display technology, whether big or small. We will help you choose or design the display that best fits your needs, while always keeping quality and budget in mind. Here at E3 Displays, we specialize in custom displays use our product selection guide today to get started on your project today!

E3 creates out of the box TFT solutions as well as MLCDs or high brightness displays that use  reflective technology or increased LED backlighting that produces a sharper image in direct sunlight. These types of displays are commonly found in wearable electronics, measurement tools and other outdoor applications. We work with you side by side to create your custom out of the box display solution that fits your unique goals and we can also work with you to add additional enhancements to maximize your display capabilities.

Reflective polarizers are the best option for direct sunlight displays but are not ideal for low light conditions. Since a reflective polarizer reflects back 100% of the light it takes in, the brighter the surrounding environment, the easier it will be to read the display. Because they are only reflecting light and not creating it, these polarizers are best suited for monochrome displays. Reflective polarizers will increase display contrast and have the minimum amount of power consumption and heat creation.

A backlight will not illuminate the display since any light placed behind the polarizer will be blocked from passing through to the front piece of glass.

Note: It is possible to use a reflective polarizer with a side-lit LED Display, or edge-lit LED Display. A side-lit display positions the LEDs above the reflective polarizer. This is a popular option since it provides a sharp contrast with the added benefit of being thinner (in the Z axis) than a LCD with a backlight.

With a transmissive polarizer, the display backlight must be on for the display to be readable. This type of polarizer does not reflect any light and so therefore, is not ideal for sunlight readability. However, the advantage of a transmissive polarizer over a transflective polarizer is that the backlight is significantly brighter. This type of polarizer is ideal for consistent low light conditions.

The backlight behind a Transmissive polarizer will be brighter than the same backlight behind a Transflective polarizer, making the overall display brighter. It is also possible to reduce the LED driving current with a goal of extending the half-life of the backlight.

The display can not be read when the backlight is off. Also, in direct sunlight the image can seem a bit ‘washed’, but E3 can add AR films to transmissive displays to limit the reflections in outdoors.

Transflective polarizers are a hybrid of reflective and transmissive. They use a combination of ambient light reflection and an internal backlight to create the display image. A display with a transflective polarizer can be used with or without the backlight being on and can also be used in low or high ambient light conditions. Combining a transflective polarizer with E3 optical bonding and contrast enhancement film lamination will create a superior all light readable display with extended battery life and reliability.

A Transflective polarizer allows the display to be read with or without the backlight on. If the Liquid Crystal Display is located in an area with good ambient light, the backlight can be turned off and the display is still readable. When the LCD is moved into poor ambient light, the backlight can be turned on and the display can still be read.

A backlight placed behind a Transflective polarizer will allow some light to pass through, but the display will not be as bright as the same backlight placed behind a Transmissive polarizer. If you need your backlight to be brighter and your display to operate in both strong and poor ambient light, there are additional methods to increase the brightness of the LED. Contact our US based technical support for ideas.

Displays that are not built for the right environment can cause strain in the viewers eyes. E3 Displays can help in choosing the correct display, like a 2500 nits display for the brightest viewing environments and lower nit displays for indoor viewing to create the perfect balance between indoor and outdoor view-ability.

No project is too big or too small. E3 can enhance displays to be all light readable from >1.0″ to 100.0″, so you can fill the smallest and largest voids for your client.

Your display is an investment into the future of your business and should never be just satisfactory. E3 enhancements are nothing short of high quality and improves the visual performance of your display so you stand out from your competition.

We took the focus away from the technology and redirected it towards your goals. We focus on passive enhancements and limiting backlight power drainage. Your display will last longer and have continuous reliability when you need it most.

TFT stands for “Thin Film Transistor.” These transistors are used in high-quality flat panel liquid-crystal displays (LCDs). TFT-based displays have a transistor for each pixel on the screen. This allows the electrical current that illuminates the display to be turned on and off at a faster rate, which makes the display brighter and shows motion smoother. LCDs that use TFT technology are called “active-matrix” displays, which are higher-quality than older “passive-matrix” displays.

Sizes can range up to 86.0″.  Each pixel in a TFT LCD is controlled by one to four transistors which offers greater control over the images and colors that it renders. TFT technology provides up to 4K resolutions, sharp contrast and wide viewing cone options.

E3 Displays specializes in enhancing displays of all technologies. We enable displays to out perform in their standard applications and increase their flexibility for use in ever changing conditions and environments.

In the reflective mode, ambient light is used to illuminate the display. This is achieved by combining a reflector with the rear polarizer. It works best in an outdoor or well-lighted office environment.

Transflective LCDs are a mixture of the reflective and transmissive types, with the rear polarizer having partial reflectivity. They are combined with a backlight for use in all types of lighting conditions. The backlight can be left off where there is sufficient outside lighting, conserving power. In darker environments, the backlight is turned on to provide a bright display. Transflective LCDs will not “wash out” when operated in direct sunlight.

Transflector bonded to the rear polarizer reflects light fromfrontas well as enabling lights to pass through the back. Used with backlight off in bright light and with it on in low light to reduce power consumption.

Transmissive LCDs have a transparent rear polarizer and do not reflect ambient light. They require a backlight to be visible. They work best in low light conditions with the backlight on continuously.

From an early age, the consumer experience is being shaped by the products we use on a daily basis. Smartphones, tablets, and other products with touch screens have forever changed the way we interact with devices. They’ve become so commonplace that everyone, even toddlers, expect many screens (TV screens included) to have touch screen interfaces.

The film reduces the reflections on the surface by canceling out a specific wavelength of light as it is reflected back to the consumer. When a specific wavelength of light passes through the AR material, some of it is reflected back to the consumer at the surface of the AR film (R1) and some of it is reflected at the surface of the cover lens (R2). The thickness of the AR film causes the reflected wavelengths (R1, R2) to be reflected exactly out of phase with each other (see diagram 1.1) so that they cancel each other out. Thus the consumer will not see their own reflection. Instead, they will see a brighter and more vivid display.

As light reflects off of the rough surface, it is scattered at different angles (see diagram 1.2) which reduces the clarity of the reflected image. Thus, the consumer will not see the bright glare of any reflected light source.

AF/AS treatment is typically applied by vacuum deposition or by a liquid chemistry process, which creates an oleophobic top coating. Since this layer is a chemical modification of the glass surface, it is very durable compared to aftermarket AF/AS spray-on films.

It has to be noted that AF/AS glass treatments do not perfectly prevent fingerprints. They only cause finger oils to bead on the surface, which makes them less noticeable and also much easier to clean off the screen.

Another benefit of the AF/AS coating is the “feel” or user perception of the treated surface. Because the surface is smooth, the finger will glide more easily compared to a non-treated surface. A non-treated cover lens surface can cause the user’s finger to stick, skip, feel like it’s being dragged, or even make drawing a singular line on the screen difficult so that it becomes a dotted line.

Not all treatments can be combined. Please contact our experienced sales and technical staffto determine which treatment is best for your application.

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.

First, the ITO film layer needs to be deposited on the TFT glass, so that there is a smooth and uniform ITO film on the whole TFT glass. Then, using ionized water, the ITO glass is cleaned and ready for the next step.

Next, a photoresist is applied to the glass on which ITO film is deposited, and a uniform photoresist layer is formed on the ITO glass. After baking for a period of time, the solvent of the photoresist was partially volatilized to increase the adhesion of the photoresist material to the ITO glass.

Ultraviolet light (UV) is used to illuminate the surface of the photoresist through a pre-made electrode pattern mask, which causes the photoresist layer to react. The photoresist is selectively exposed under ultraviolet light by covering the photoresist on the glass coated with the photoresist.

The exposed part of the photoresist is then washed away with the developer, leaving only the unexposed part, and the dissolved photoresist is then washed away with deionized water.

Then etch off the ITO film without photoresist covering with appropriate acid etching solution, and only retain the ITO film under the photoresist. ITO glass is conductive glass (In2O3 and SnO2). The ITO film not covered by photoresist is easy to react with acid, while the ITO film covered by photoresist can be retained to obtain the corresponding wire electrode.

Stripping: High concentration of alkali solution (NaOH solution) is used as a stripping solution to peel off the remaining photoresist on the glass so that ITO glass can form ITO graphics exactly consistent with the photolithography mask.

Rinse the basic label of glass with an organic solution and remove the photolithographic tape after reaction to keep the glass clean. This completes the first thin-film conductive crystal process, which generally requires at least five identical processes to form a complex and sophisticated pattern of electrodes on the glass.

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.

Then, the organic polymer directional material is coated on the surface of the glass, that is, a uniform directional layer is applied to the appropriate position of ITO glass by the method of selective coating. Meanwhile, the directional layer is cured.

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.

A polarizer is an optical plate that allows only light from a certain direction to pass through. It is an optical element that converts natural light into straight polarized light. The mechanism of action is to make the vertical direction light pass through the straight incident light after passing through the vertical polarizer, and the other horizontal direction light is absorbed, or use reflection and scattering and other effects to make its shade.

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.

However, no matter CCFL backlight or LED backlight is placed in various ways, the nature of the backlight source cannot be a surface light source, but a linear light source or point light source. Therefore, other components are needed to evenly distribute the light to the whole surface. This task is accomplished by the diffuser plate and diffuser plate.

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.

The backlight system also includes a backlight module laminator, located behind the backplane. In the CCFL backlight era, you can often see the long strip laminator like the one above, with each coil responsible for a set of tubes.

However, it is much simpler to use a side white LED as a backlight. The small circuit board on the far left of the figure above is the backlight of the LED.

This is the general structure of the backlight system. Since I have never seen the backlight mode of R.G.B LED, I cannot tell you what the backlight mode is like. I will share it with you when I see it in the future.

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.

These are films used on the front surface of smartphones, televisions, and other displays. They improve visibility by minimizing reflection of external light while also enhancing strength and durability. Toppan offers films for various purposes. These include Low Reflection (LR) Film, which prevents reflection and static buildup while providing high contrast, and Anti Glare (AG) Film, which provides outstanding glare and reflection reduction.

Our daily experience is typically with displays that emit light, our phones, televisions, monitors, tablets and watches all use technologies such as LCD (with LED backlights) or OLED or direct view LED. However reflective displays are also commonplace, calculator displays, shelf-edge labels, and of course Kindle e-readers. But there is significantly more potential for reflective displays, especially for outdoor signs where their significant benefit of being sunlight readable and low power provide considerable opportunity.

My first imaginings of the future of displays were along the lines of living room walls and cereal boxes being turned into displays, the stuff of science fiction. Nearly 50 years later we are still not at that stage, not commercially in any case. Well before knowing the terminology or the implications concerning power, ambient light, etc, I favored the idea of e-paper as the future of display technology. Today, after many years in the display industry, I am more pragmatic and favor whatever best meets the needs of the application and is actually available, but reflective displays are a key part of the display technology mix.

There are some very significant benefits to these reflective display technologies for certain applications, for example outdoor signage where they offer:

Very low power. The reflective display technologies typically only use power to change the image or require a very small amount of power to maintain their image. The clear benefit of this is that they can be installed in locations where they are dependent on solar power.

LCD is best known as an emissive display technology for its use in televisions and mobile devices, it normally has a backlight and is part of an emissive display assembly. However LCD doesn’t emit light, the backlight to the display assembly provides the light, and these days that is usually made using LED, the LCD acts as a shutter allowing light to pass or not. LCD can work very effectively as a reflective display but efforts to make large or color reflective LCD displays have not been particularly successful (so far). There is a hybrid known as transflective, this can operate as both reflective and backlit.

Kent Displays have commercialized a use for reflective LCD technology with their Boogie Boards, note however that the Boogie Board is not an electronic display, see https://kentdisplays.com/.

E Ink, a market leader for reflective displays with a history dating back to 1997, saw their first major commercialization breakthrough being e-readers however they are now a major provider to the electronic shelf edge label market and have a growing presence in the outdoor digital sign market. They explain their technology here: https://www.eink.com/electronic-ink.html. As detailed on the E Ink website (https://www.eink.com/application.html) the number of applications has grown significantly, including larger higher resolution signage displays. A significant advantage with these e-paper displays is that they are both sunlight readable and bistable, ie they hold their image without power, and only require very low power to change the image making them suitable for solar or wind powered installations. Digital View has developed a driver for the larger E Ink panels: https://www.digitalview.com/controllers/epm-100-eink-interface.html.

Another company with a charged particle display technology for reflective displays is Clearink. An explanation of their technology is here. https://www.clearinkdisplays.com/technology. They have apparently seen a market opportunity with e-readers, shelf labels and wearables.

Electrochromic displays are based on the property of a material to change from transparent to opaque when a voltage is applied. They make effective reflective displays though they require a small amount of power to hold their On state. As far as I am aware they are not bistable like some of the other technologies, they need a very small amount of power to maintain their state. They also promote the benefit of being cost-effective to mass-produce.

RDot, https://rdotdisplays.com/, and Ynvisible, https://www.ynvisible.com/, are examples of electrochromic display solutions that have been commercialized. RDot has a good explanation of their technology at: https://rdotdisplays.com/displays.

Electro-wetting involves moving a liquid so that it is visible or not. Here is a video from 2013 that explains and demonstrates the technology being used to make a high resolution display: https://www.youtube.com/watch?v=Bf1GjCaYzYg (Samsung sold this business to Amazon in 2013). However, it seems the direction might be for outdoor display use.

eTulipa, https://etulipa.com/, are bringing electro-wetting display technology to the market and have a number of real world installations viewable on their website.

Liquivista, one of the pioneers that I recall for electro-wetting. As noted in Wikipedia, the company was started as a spin-off from Philips, then bought by Samsung, then Amazon then closed in 2018. A company called LookGadgets acquired the web domain and have written up a good explanation of the electro-wetting technology, see: https://liquavista.com/

The only other reflective display technology that comes to mind are electro-mechanical displays. These use mechanical shutters and some people may recall the click clatter of the train station timetable displays.

Flipdot https://flipdots.com/en/home/: I was pleased to find this excellent demonstration of an existing product: https://flipdots.com/en/products-services/small-7-segment-displays/, they also have flipdot panels: https://flipdots.com/en/products-services/flip-dot-boards-xy5/.

This application is a Divisional of Copending U.S. patent application Ser. No. 11/512,137, filed Aug. 30, 2006, and claims priority to Korean Patent Application No. P2006-009638 filed Feb. 1, 2006, which are hereby incorporated by reference in their entirety. BACKGROUND OF THE INVENTION

Embodiments of the invention relate to reflecting light, and more particularly, to a reflective plate and method for manufacturing the same and a backlight unit for a liquid crystal display (LCD) device using the same. Although the embodiments of the invention are suitable for a wide scope of applications, it is particularly suitable for maintaining uniformity of temperature across a reflective plate and a method for manufacturing the same, and a backlight unit for an LCD device using the same.

In general, a liquid crystal display device includes a liquid crystal display module, a driving circuit for driving the liquid crystal display module, and a case for protecting the driving circuit and the liquid crystal display module. The liquid crystal display module has a liquid crystal display panel having a matrix of liquid crystal cells in which liquid crystal is injected into a gap between two bonded glass substrates. Switching devices are positioned in each of the liquid crystal cells for switching signals applied to the liquid crystal cells. The liquid crystal display module also includes a backlight unit for providing light to the back side of the liquid crystal display panel. Optical sheets for scattering and diffusing the light from the backlight unit are positioned between the liquid crystal display panel and the backlight unit.

The liquid crystal display panel, the backlight unit, and the optical sheets of the liquid crystal display module are packaged together to prevent light leakage and to protect these components from an external impact. The glass substrates of the liquid crystal display panel in the liquid crystal display module are susceptible to damage due to an external impact. A top case is used to package the backlight unit and the optical sheets together with the liquid crystal display panel. Further, the top case runs along the edges of the liquid crystal display panel such that the liquid crystal display panel can still be viewed. Accordingly, the top case protects the glass substrates of the liquid crystal display panel in the liquid crystal display module from an external impact.

FIG. 1 is an exploded perspective view of the related art liquid crystal display device. As shown in FIG. 1, the liquid crystal display device 10 includes a liquid crystal display panel 20, and a backlight unit 30 for providing light to the liquid crystal display panel 20. The backlight unit 30 includes a fluorescent lamp 31 for emitting light, a lamp housing 32 surrounding the fluorescent lamp 31 in a U shape, a light plate 33 for distributing light from the fluorescent lamp 31, and a reflective plate 34 for reflecting light into the light plate 33. A protective sheet 35, a first prism 36, a second prism 37 and diffusion sheets 38 are positioned in succession on the light plate 33. A bottom cover 39 for receiving and holding both the liquid crystal display panel 20 and the backlight unit 30.

The backlight unit 30 provides light to a display region A of the liquid crystal display panel 20. The display region A of the liquid crystal display panel 20 has a matrix of liquid crystal cells (not shown) in which liquid crystal (not shown) is injected into a gap between two bonded glass substrates (not shown). The liquid crystal display device 10 also includes a driving circuit 40 for driving the liquid crystal display panel 20.

When the fluorescent lamp 31 at one edge of the light plate 33 emits light, the lamp housing 32 focuses and directs the light toward an edge of the light plate 33. Then, the light from the edge of the light plate spreads throughout the entire surface of the light plate 33 and is redirected toward the display region A of the liquid crystal display panel 30 through the protective sheet 35, the first prism 36, the second prism 37 and the diffusion sheets 38. A thin film transistor on the liquid crystal display panel controls transmission of the light through a pixel in response to a signal from the driving circuit of the liquid crystal display device. Together, the pixels display a picture on the display region of the liquid crystal display panel.

FIG. 2 is a plan view of the related art backlight unit, and FIG. 3 is a cross-sectional view of the related art backlight unit in FIG. 2 along line As shown in FIGS. 2 and 3, the related art backlight unit 50 includes a lamp 51 for emitting light, a lamp housing 52 for holding the lamp 51 and reflecting light from the lamp 51 toward one direction, and a light plate 53 for distributing the light from the lamp 51 into a planar light and providing the planar light to a liquid crystal display panel (not shown). The related art backlight unit 50 also includes a reflective plate 54 on a back side of the light plate 53 for reflecting the light toward the liquid crystal display panel, an optical sheet 55 on the light plate 53 for enhancing a luminance of the light, and a cover bottom 56 for supporting an assembly of the lamp housing 52 and the light plate 53. The reflective plate 54 under the light plate 53 re-reflects light directed thereto through a bottom surface of the light plate 53, thereby increasing light utilization efficiency.

The lamp 51 is typically a cold cathode fluorescent lamp, and the light plate 53 has a scattering pattern (not shown) formed at a predetermined portion thereof for scattering light and a reflecting portion (not shown) in which the light is internally reflected. The light plate 53 has a display region (not shown) and a non-display region (not shown). Light entering into the light plate 53 through a light incident surface at an edge of the light plate 53 from the lamp 51 advances toward the display region of the light plate 53 through the non-display region in which the light is internally reflected. The light is scattered by the scattering pattern in the display region.

FIG. 4 is a cross-sectional view of the lamp housing in the related art backlight unit. Referring to FIG. 4, the lamp housing 52 has aluminum (Al) film 52aand a reflective film 52b,such as polypropylene (PP) or Polyethylene Terephthalate (PET), bonded together with an adhesive 52c.The reflective film 52bis placed on an inner side of the lamp housing 52 and the aluminum film 52ais placed on an outer side of the lamp housing 52. More specifically, the reflective film 52bportion is on the inner side of the lamp housing 52 for reflecting the light from the lamp 51 in one direction, and the aluminum film 52ais on the outer side for dissipating heat from the lamp 51 to outside of the liquid crystal display panel. The reflective plate 52 of the related art backlight unit is a reflective film, such as polypropylene (PP) or Polyethylene Terephthalate (PET), coated onto a back side of the light plate 53.

Because the backlight unit has the reflective film on the inside of the lamp housing and on the backside of the light plate, heat from the lamp can not efficiently dissipate to the bottom cover through the lamp housing. In effect, the reflective films act as insulation. Thus, heat builds up within the backlight unit that effects the liquid crystal display panel. Such heat build-up can cause deformation of the components within the liquid crystal display panel. Moreover, deformation of the optical sheet and the large view angle polarization plate of a LCD device causes light leakage at upper and lower corners of the display panel. SUMMARY OF THE INVENTION
