One of the advantages of designing a custom display is the ability to reduce your LCD display’s thickness by selecting a thin ITO glass; which is key to a thin LCD module.

The structure of the LCD is very basic, but a special glass called ITO glass is used in constructing the display. Three sides of the ITO glass are glued together with an adhesive or epoxy. Both the ITO glass and the nematic fluid used are transparent. There is a small gap of one or two millimeters between the top and bottom layer of glass. A nematic fluid is then injected between the layers. Finally, a cap is placed on the fourth side to keep the fluid from leaking out.

A polarizer is applied on both the top and bottom layer of glass. The polarizer on the top layer is always Transmissive, whereas the bottom layer can be Reflective, Transflective or Transmissive. For more details on the different types of polarizers, please read our article: LCD Polarizers.

ITO glass can be cut to custom dimensions, but smaller sized glass can add a significant cost increase to the overall cost of the LCD. The reason for the increased cost is the amount of labor and time required to add a polarizer to the small piece of glass.

Many times customers require the display to be as thin as possible; one method to achieve a thin LCD module is to select a thinner ITO glass. Keep in mind that the thinner the glass, the more expensive and the higher the fallout rate.

Note:Fallout rate does not mean failures of the LCD’s in the field; fallout is when the display fails on the manufacturing line. If the display fails in production, it is discarded before it is shipped to the customer.Once the display passes QA (Quality Assurance) it will operate normally for the life of the product.

It is possible to add a backlight to the monochrome display to make the display readable in low or no light conditions. The challenge of adding a LED backlight is that it increases the thickness of the LCD by as much as 5mm to 9mm.

In the photo above, a segmented LCD is combined with a LED backlight and backlight diffuser. A printed circuit board (PCB) is used to hold the assembly together. As the backlights name suggests, a light is placed behind the bottom layer of ITO glass.

Note: A backlight diffuser’s job function is similar to the lamp shade used on a table lamp. It disperses the light from each led to provide a more uniform appearance. Without the diffuser, there would be hot and cold spots on the display. A hot spot is where the backlight is too close to the LCD glass and it is overly bright; the area around the hot spot is dimmer and is referred to as a ‘cold spot’.

There are four methods to reduce the thickness of the LCD display/backlight combination; thereby creating a thin LCD module. However, these solutions do not apply to TFTs, VFDs, LEDs or OLEDs (Organic Light Emitting Diodes).

In the integration the backlight is sandwiched between the LCD and PCB. The LCD’s leads (pins) are then soldered to the PCB securely holding the backlight in place. This helps to create a thin LCD module.

Advantages of a PCB mounted LED backlight:The PCB combines the backlight and the LCD; this is great in applications that operating in environments of heavy vibration.

It is possible to build the PCB with only one or two layers to reduce the thickness, but current design practices call for a separate plane for power and ground. Also, a thinner board may not be as strong.

Another way to combine the LCD and the LED backlight is to use either a plastic clip to bind them together, or to use an epoxy or adhesive. There are advantages and disadvantages to both, but we suggest the plastic clip solution.

This method requires a one-time tooling fee to design and prototype a small, flexible plastic clip that holds the backlight and display together. The clip only adds a few pennies to the overall cost of the LCD combination.

This method is accomplished without any tooling cost and only adds a penny or two to the overall cost of the LCD assembly, but we do not recommend this approach.

An edge-lit display means that the LEDs are not placed behind the bottom layer of glass, but along the edge between the two layers of glass. This alone helps to create a thin LCD module.

Disadvantages to an Edge-lit display:One of the Challenges of this solution is that it increases the size of the overall display in the X and Y directions (Length and Width). Which means the sides of backlight will stick out beyond the LCD.

Side-lit displays work well for smaller size LCDs, but create hot spots around the edges if the display is too large. This is more evident with a white LED edge-lit; since white LEDs are much brighter than other colors and sometimes need to be dimmed to reduce their starkness.

EL backlights are AC (Alternating Current) driven, this requires an inverter either on the LCD or on the customers’ board. Inverters add extra cost and labor.

LEDs are DC (Direct Current) driven and do not require an inverter. Many times the voltage for the LED backlight is the same as for the LCD which means one less power supply is required.

While there are many different manufacturers of LCD monitors, the panels themselves are actually only manufactured by a relatively small selection of companies. The three main manufacturers tend to be Samsung, AU Optronics and LG.Display (previously LG.Philips), but there are also a range of other companies like Innolux and CPT which are used widely in the market. Below is a database of all the current panel modules manufactured in each size. These show the module number along with important information including panel technology and a detailed spec. This should provide a detailed list of panels used, and can give you some insight into what is used in any given LCD display.

Note:These are taken from manufacturer product documentation and panel resource websites. Specs are up to date to the best of our knowledge, and new panels will be added as and when they are produced. Where gaps are present, the detail is unknown or not listed in documentation. The colour depth specs are taken from the manufacturer, and so where they specify FRC and 8-bit etc, this is their listing. Absence of such in the table below does not necessarily mean they aren’t using FRC etc, just that this is how the manufacturer lists the spec on their site.

A mil (or thou) is a unit of thickness that equals one thousandth of an inch (0.001 inches). Example: 10 mils = 0.010 inches. Mil thickness is commonly used in manufacturing in non-metric countries to measure the thickness of various thin materials, such as paint layers, thin films, foils, plastic sheets, and coatings.

Ultrasonic thickness gauges can measure paint thickness nondestructively. For example, Olympus gauges such as the 72DL PLUS instrument offer features that can calculate total paint thickness and simultaneously display paint thickness measurements of up to six individual layers. Paint thickness is expressed in mils or microns.

Eco2 OLED is a technology that removes the polarizer, which is used to reduce the reflection of external light and integrates its functionality into the OLED panel layer. The Eco2OLED display is eco-friendly by reducing the use of plastics. The technology improves energy efficiency and reduces power consumption.

compared with traditional leds, minileds have smaller particle size and higher brightness, which can bring better display effects to the lcd with a miniled back­light unit. meanwhile, it is more energy-efficient and supports accurate local dim­ming to avoid the uniformity problem that occurs with led backlight units. the active-matrix (am) driving glass substrate technology adopted by the chip-on-glass (cog) miniled backlight unit from boe is based on semiconductor technology and uses a glass substrate through boe’s lateral processing technology. glass is more suitable for making led backlight arrays with dense arrange­ment and heat concentration. the miniled unit is directly bonded to the glass substrate to realize the high-speed transfer of the led chips and can realize precise, independent dimming control of the back­light unit.

The xQDEF Diffuser Plate brings together the color and brightness performance of QDEF quantum-dot (QD) technology with the precise light diffusion necessary for perfect contrast levels in miniLED and full-array local-dimming LCDs. As a direct replacement for diffuser plate components in direct-lit LCDs, the xQDEF Diffuser Plate simplifies the display assembly process, allowing display makers to design and build the most cost-effective displays with the widest color gamut. Compared with other wide color gamut solutions, the xQDEF Diffuser Plate implementation results in close to no additional material costs. By the end of 2021, more than a million TVs with xQDEF Diffuser Plates inside shipped into the market.

With its 32‐inch LCD panel, 6K Retina resolution, and over 20 million pixels, Apple Pro Display XDR (Fig . 1) sets a new bar for the capabilities of a professional display. Designed for pro users who rely on color accuracy and true‐to‐life image reproduction, such as photographers, video editors, 3D animators, and colorists, Pro Display XDR delivers the most comprehensive set of features ever offered on a display in its price range.

Here"s how Pro Display XDR is engineered to produce industry‐leading imagery: Traditional LCD displays use edge‐lit backlight technology to diffuse light evenly across the display at the same brightness level. Instead, Pro Display XDR uses a locally dimmed backlight with 576 individual LEDs, controlled by an advanced algorithm in the timing controller chip. As a result, the display can exhibit incredibly bright, color‐accurate image areas and deep blacks simultaneously, delivering its 1,000,000:1 contrast ratio and up to 1600 nits peak brightness. An advanced thermal management system supports the display to maintain peak brightness indefinitely in environments up to 25° C. With these features, Pro Display XDR introduces Extreme Dynamic Range (XDR), far outperforming typical HDR brightness specifications for desktop displays and enabling pros to work with true‐to‐life content.

Pro Display XDR also incorporates several innovations to optimize image quality compared to traditional LCD displays. First, to minimize “blooming,” a halo effect surrounding bright objects on dark backgrounds, an Apple‐designed cavity reflector is layered on top of the LEDs and optimized geometrically. Along with several additional custom lenses and reflective layers, it directs the light upward while reducing halo effects and preserving light uniformity.

The display industry has experimented with various technologies to better reflect natural images and a wide range of colors on screens, and with the emergence of LED local dimming and HDR, display performance has substantially improved. However, traditional LCD screens’ brightness has long been considered relatively high in low grayscale. In other words, it isn"t black enough, and it"s difficult to use local image technology to differentiate the sense of depth with a high‐contrast ratio.

As a breakthrough in thin‐film transistor (TFT)‐LCD technology, BOE"s dual‐cell panel (Fig . 2) — referred to as “BD Cell” for short—offers several important technical advancements that conventional LCD screens don"t. The display uses pixel‐level ultra‐fine backlight control technology and a brand‐new integrated circuit (IC) driving technology to make the million‐level contrast ratio rate and 12 bits’ color depth come true, accurately displaying more natural and true‐to‐life colors.

The contrast ratio of a conventional LCD screen is 3,000:1 with 0.2 nits as the lowest brightness. The BD Cell"s screen is capable of raising the contrast ratio up to 150,000:1 and decreasing brightness to 0.003 nit. In terms of combining LED local dimming with BD Cell technology, the contrast ratio can be as high as 2,000,000:1. Moreover, while a conventional LCD screen"s color depth is 8 bit, BD Cell is capable of boosting the color depth as high as 12 bit with an enhanced IC driving algorithm. On the other hand, BD Cell incorporates advantages of an LCD screen"s stableness and technological maturity, with no image sticking.

In the end, “the successful development of BD Cell substantially increases the lifespan and the competitiveness of LCD technology, bringing a better visual experience to consumers and more possibilities for the entire display industrial chain,” says Feng Yuan, vice president of BOE Technology Group.

To achieve those specifications, Samsung has developed highly effective electroluminescent material and highly durable components. To make an inward foldable display with a bending radius of 1.5 millimeters (mm), all the layers within the panel should be folded without causing any cracks. As a result, the foldable display employs a cover window made of flexible, hardened plastic. Samsung says that it successfully reduced the thickness by more than 50 percent by taking advantage of materials that enable ultra‐thin layers. Furthermore, the stress of various layers (including the TFT, light‐emitting layers, polarizing plate, and cover window) is appropriately dispersed, allowing the product to pass a strict bending test more than 200,000 cycles.

Nonvibrating surface haptic technology introduces new options for automotive manufacturers to reimagine the vehicle"s interior design and feel. Car manufacturers can create a uniform or harmonious touch experience across multiple surfaces—not just the display screen, but also the steering wheel, exterior door handle, and even upholstery. According to Tanvas, automotive manufacturers can implement its technology with a combination of a proprietary controller solution (which performs multitouch sensing and haptic control), supplied in various forms (including as an IC or as a module), and transform the multitouch sensor panel to a combined multitouch and haptic actuator for any surface.

Although quantum dot (QD) technology realizes a high color gamut for LCD, most QD materials are cadmium (Cd)‐based, raising concerns about their potential toxicity: Exposure to cadmium has been connected to cancer and other serious health issues, as well as environmental harms. As a result, Cd‐based QD materials are not widely accepted in the display market, and the industry has shifted its focus to finding nontoxic alternatives. Still, Cd‐free QD materials can bring their own challenges, including issues with low luminance and color purity.

Because one of Toray"s core offerings is organic emitting materials with high color purity for organic EL devices, the company wondered if they might be useful for a high color gamut LCD and began developing the SCO sheet (Fig . 6). In the beginning, the biggest issue with the organic emitting materials was their lifetime. However, Toray ultimately achieved a lifetime 1,400 times longer compared to the initial development stage.

According to the company, their SCO sheet is especially innovative for a few reasons. First, the high color purity of Toray"s organic emitting material is based on a full width at half maximum (FWHM) parameter that"s much narrower than any other organic emitting materials so far developed. So by using the SCO sheet, a high color gamut LCD can be realized. In particular, the sheet can cover both Digital Cinema Initiatives (DCI)‐P3 and Adobe specifications.

Second, Toray says its original organic emitting material has a higher quantum efficiency than that of non‐Cd QDs. Therefore, an approximately 10 percent higher luminance can be realized with the sheet than with non‐Cd QDs. For that reason, the SCO sheet can contribute to lower power consumption of the LCD panel.

Because Toray"s SCO sheet is free of toxic elements, it"s not restricted by various environmental regulations, including the European Unions’ Restriction of Hazardous Substances (RoHS) Directive. Finally, with the sheet, more than 99 percent of DCI and more than 99 percent of Adobe coverage can be achieved in one LCD panel. (According to the company, non‐Cd QDs can"t say the same.) Recently, in the PC monitor market, there has been a strong demand for compatibility of DCI and Adobe in one PC monitor. Toray believes that with the SCO sheet, it will be able to develop a new PC monitor market.

Although OLED is a well‐known way to apply organic electronics materials to the display industry, this is the first instance of applying organic emitting materials to the LCD industry, an achievement that expands the possibilities of organic electronics materials.

A 7‐inch OLED was selected for the virtual exterior mirror. In early test drives, Senner notes, Audi realized that the limited contrast of an LCD and especially the slow response time in low temperatures was a significant issue. “So it became clear very early, that we have to use an OLED display for this application, because with the dark black and the temperature, independent fast switching‐time OLED is the best solution,” he says.

The camera is integrated into the hexagonal end of the virtual mirror"s flat supports and its images are digitally processed and displayed on high‐contrast, 1,280 × 800‐pixel OLED displays in the transition between the instrument panel and door.

LCD screens are popular for both smartphone screens as well as computer monitors and televisions. LCDs are either backlit or edge-lit. The light shines through a liquid layer sandwiched between polarized glass layers. Electric current is used to control which pixels are on or off. The current adjusts the crystal orientation, thus allowing or prohibiting light from passing through the polarizers.

LED (light emitting diode) displays are typically a grid of arranged red, green, and blue LEDs. The LEDs act as pixels and are controlled to display the desired image. Sometimes, LEDs are chosen to be the source used for backlighting LCD displays. In this case, the display type would be an LED LCD display.

OLED screens are made up of a carbon-basedfilm that is layered between an anode and a cathode. The electrodes excite the charge carriers. The charge carriers move and recombine in the carbon layer, while some reach an excited state. When they relax from the excited state, light is emitted. Since the primary emissive layer is built into the screen (as opposed to LCD where it must be illuminated in other ways, i.e. backlit or edge-lit), this makes the OLEDscreen thinner. More layers of other materials can be added for durability and reinforcement purposes.

There are subcategories of OLEDs. Active matrix LEDs are controlled (as the name implies), actively. Each pixel can be located and individually controlled through a thin film transistor and capacitor corresponding to each LED. Some screens can be PMOLED, which stands for Passive Matrix OLEDs. With PMOLED displays, the entire screen is split into a grid and controlled using circuitry controlling that section of the grid. Passive control is a slower and less precise method of controlling the LEDs than using active control. Using active control also permits each of the LEDs to be turned completely off. The ability to completely shut off each LED results in improved contrast in images when compared to LCD screens.

Obviously, between the screen types mentioned, some will perform better in some areas than others. When it comes to efficiency, LCD screens tend to be less efficient than LED or OLED screens. However, depending on the brightness of an OLED screen, an OLED one may consume more power than both LED and LCD screens. This is because OLED screen brightness is directly related to its energy consumption. At a normal brightness, LCD screens perform better in bright sunlight than the other two options.

Organic LEDs have an abbreviated lifetime in comparison to non-organic LED counterparts. The blue pixels experience the fastest degradation, followed by the greens, and finally the reds. In fact, the lifetime of some OLED screens have been found to be anywhere from a roughly two to three times shorter than that of LCD or LED screens. Manufacturers of OLEDs are working to improve the lifetime.

LCD screens tend to be thicker and heavier than LED or OLED screens. This is a consequence of the added layers for the polarization and lighting elements. Since OLED screens can be created in sheets, this makes them simpler to produce than LCD screens. The thinness of OLED screens has allowed for some flexibility—in the most literal sense. The flexibility of OLED screens has helped facilitate the ability for companies to produce foldable smartphones. Both LED and OLED screens are more expensive to create (thus, also more expensive for the consumer) than LCD, though.

OLEDs have a wider field of view than LCD screens. Some OLED displays have been reported to have a field of view as wide as 170 degrees. Since a key component to LCD functionality is polarization, there are some angles at which the display will not be viewable.

Display contrast is improved when considering OLED screens to LCD screens. The ability to turn the pixels completely off in LED/OLED screens allows for better battery life for devices having these display types.

One may wonder which type of screen offers the best image resolution. The resolution is not inherent to the nature of the screen’s illumination, but by the pixel count. One reason display resolutions have improved is simply the number of pixels being packed into each inch of the screen. When the resolution of the screen meets or exceeds the resolution of the eye, the display can produce very sharp images. At the typical viewing distance under normal conditions, this kind of resolution means that a person would not be able to resolve the individual pixels that comprise the screen. This provides a better, crisper image for the user. LCD, LED, and OLED screens are all available with comparable resolutions.
