Display device technology and performance is advancing at a remarkable pace. The design and manufacture of Liquid Crystal and Light Emitting Diode Displays that include touch screen layers is very demanding. These display components and assemblies can be characterized with Bristol Instruments non-contact thickness gauges to sub-micron accuracy.

In both LCD and OLED displays, producing these cells – which are highly complex – is by far the most difficult element of the production process. Indeed, the complexity of these cells, combined with the levels of investment needed to achieve expertise in their production, explains why there are less than 30 companies in the whole world that can produce them. China, for instance, has invested more than 300 billion yuan (approximately $45 billion USD) in just one of these companies – BOE – over the past 14 years.

Panox Display has been involved in the display industry for many years and has built strong and long-term partner relationships with many of the biggest OLED and LCD panel manufacturers. As a result, we are able to offer our clients guaranteed access to display products from the biggest manufacturers.

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.

Spherical particles used to control the thickness of the liquid crystal layer must meet stringent requirements such as precise particle size, tight particle size distribution, suitable hardness, and excellent resistance against heat, cold and chemicals.

Purchasing an LCD monitor can be a difficult task at the best of times. Knowledgeable buyers have to consider many aspects of their future screen, not just basing a decision on price and marketing hype. Of course decisions are ultimately driven by a buyers budget, but one must always consider the things which will make the screen suitable to their uses, which are where technologies, features, connections and design come into play. Panel technology is not always discussed by manufacturers but is one of the most important aspects to consider when buying a new screen as it will tell you a lot about the real-life performance you can expect from the display, and ensure you are buying a screen suitable for your requirements. Fortunately we are here to help and you can read our in depth panel technologies article to help you in your quest.

One thing which many buyers will be unaware of is that all LCD displays are supplied with a protective filter layer on the front of the panel itself. This coating is used to protect the panel from damage, filter and diffuse the light output and in many cases reduce glare from other light sources in your workspace. What is also tricky to understand is that different panels can have different types of coating, varying considerably by panel technology and manufacturers. This article is designed to help highlight some of those differences so that readers can make an informed decision about their next monitor purchase.

The most common type of protective coating is ‘Anti-Glare’ (AG). This is often described as a matte coating as it is non-reflective to the user since it diffuses rather than reflects ambient light. It provides a method for manufacturers to avoid glare on the viewing surface from other light sources and has been used in the LCD monitor market for many years since the first TFT displays started to emerge.

This matte coating is included as an outer polarizing later which has been coarsened by mechanical or chemical processes. This achieves a surface coating which is not smooth and so can diffuse ambient light rather than reflect it. What is particularly important to understand is that this AG coating can be applied to panels with varying thicknesses, which has an impact on the anti-glare properties, but also on the underlying image of the screen. Where the coating is particularly thick and aggressive, the image from the screen can deteriorate as the light being emitted is also affected. This can have some impact on contrast and colour vibrancy and the perceived image can sometimes look dull as a result. Sharpness degradation can also occur in some extreme cases where AG coating is too thick. Users may also sometimes see the graininess of the coating, particularly when viewing white or light backgrounds. This can be particularly distracting for office work and images can look grainy or dirty if the coating is too aggressive. I would point out that not everyone would even notice this at all, and many users are perfectly happy with their screens even where aggressive AG is used. It’s just something to be wary of in case you have found problems with image quality in the past or are susceptible to it.

Some users have even taken matters into their own hands and removed the AG coating from their screens to produce a glossy surface. This will of course void your warranty and should be done with caution and entirely at the users risk. We mention it here as the above images are a good demonstration of the aggressive coating applied to the screen in some cases. You can see from the top picture the film being peeled off to leave a glossy reflective surface underneath. The second image is of course exaggerated quite a lot but you can see how the image is affected when the photograph is taken with the AG coating in front, on the right hand side. Of course this is far less obvious when the coating is in contact with the surface of the screen but it’s a fairly good demonstration of the coating being used in some cases (note, these were taken from an LG.Display IPS panel on the Dell U2312HM).

It is important to realise that different manufacturers tend to use different levels of AG coating, often linked to the panel technology they are developing. See our following sections for more information about specific panel manufacturers and technologies.

As an alternative some manufacturers choose to supply their screens with a glossy screen surface. This gives somewhat of a “wow factor” when you first see the screen and has often been used by manufacturers like Apple for their screens and tablets. The glossy panel coating is sometimes combined with a glass protective layer to give a hard exterior surface to the display and to emphasise that overall glossy appearance.

Where glass coatings are applied as an additional protective layer buyers should also be aware that there is sometimes the risk of trapped dust or particles behind the glass which can become an annoyance over time. Some screens are completely free from this, but it’s just something to be aware of (e.g. dust issues were found on some Hazro’s HZ27WA/C/D screens where glass layers were used). Glass layers are also often provided on touch-screen displays for that added level of protection.

Glossy screen coatings have been offered over the years in several forms including older models featuring Sony X-Black, Acer CrystalBrite and NEC OptiClear technologies. Apple have used glossy coatings on their Cinema Displays for many years and in fact a lot of the modern glossy offerings are based on IPS panels. More recently other manufacturers like Hazro (HZ27WA/C/D) and DGM (IPS-2701WPH) have produced screens based on the 27” glossy IPS panels available. Samsung have also released their first glossy PLS panel in the Samsung S27B970D.

As we’ve already mentioned, the type of coating applied to a panel is very dependent on the manufacturer and the technology being used. Trends have emerged over the years and here is a summary of the typical coating usage from different panel solutions:

LG.Display IPS – These panels are often criticised for their aggressive AG coating. Where AG is used it is normally very aggressive and some people find the images are too grainy or dirty looking. As an example the Dell UltraSharp series (U2410, U2412M, U2711, U3011) are all using aggressive AG coating on their IPS panels. Some IPS panels are provided with a glossy screen coating as an alternative which avoids issues with grainy coating, but can result in distracting reflections.

AU Optronics AMVA – Modern versions of these panels are provided with a light AG coating which is sometimes referred to as semi-gloss. It is not overly grainy or obtrusive.

Samsung PLS – early versions of the panels were provided with a light AG coating, similar to that of AMVA panels although not quite as low haze. It was not overly grainy or distracting. More recently PLS panels have also been supplied with a glass glossy coating. The technology is in its infancy and so it is hard to establish a future trend.

TN Film panels – these are nearly always provided with AG coating although some glossy models have been produced from time to time. Coating tends to vary but is normally considered to be ‘medium’ in terms of its aggressiveness. Not as aggressive as the IPS panels, but not “semi-gloss” like AMVA offerings.

Above is a comparison of macro images taken of varying panel types. This was designed to capture the structure of the panel at a pixel level but can also be used to demonstrate the coating type being used and the resulting image clarity. You will see that the aggressive AG coating of the IPS panels leads to a blurry and grainy image, but the glossy equivalent leaves a clear and crisp view of the underlying pixels. TN Film is a medium AG coating and while not as aggressive as the IPS AG coating, it can lead to noticeable graininess in some cases. AMVA has a light AG coating and as you can see does not deteriorate the image quality too much.

This hopefully gives you a summary of the common types of coating used on the main panel technologies in the market. Of course there are always variations and so we will try to discuss the coatings in our reviews so you have an idea.

LCD displays and touch screens are in demand. They offer a sleeker, less cumbersome alternative to a mouse and keyboard or wired touch pad. And since the user can interact directly with the device’s interface, the possibilities for innovation are endless — from elevators and mobile medical equipment to industrial automation.

For many years, electronic device manufacturers generally incorporated five to seven layers of touch screen technology in the manufacture of their products — the LCD panel layers, the touch sensor layer, and the protective top cover or outer glass. Typically a touch screen is mounted on top of the LCD display and either secured with a high-performance double-sided tape, which leaves an air gap, or a silicone gel, called optical bonding, that fills air gaps and enhances readability.

Since 2012, in-cell and on-cell touch screen technologies have taken the high volume consumer segments by storm, in particular, smartphones and tablets. Born out of similar strategies of combining layers for improved functionality, in-cell technology incorporates touch sensors into the actual LCD display panel. On-cell or G2 technology moves the touch sensor to the top cover or outer glass layer.

With fewer layers, in-cell and on-cell touch screens provide designers and engineers the ability to develop much thinner devices, locate touch sensors close to the displays, create better color saturation and visual clarity, and reduce glare. All of which make users feel like they are actually touching the display and not just the outer glass layer.

Fewer layers are beneficial to a manufacturing process as well. It reduces costs by integrating the touch screen sensor as one of the layers of the LCD display, and optical bonding takes place as part of the initial production line, eliminating the need for a secondary bonding process.

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.

Second: The thickness of the embroidery thread should be uniform, the thickness should be just suitable for the embroidery board grid, and it should be corrosion resistant. The embroidered work with uneven thickness of embroidery thread is very ugly. If the embroidery thread is too thin, the bottom plate will be exposed, which will affect the appearance of the finished product. If it is too thick, the thread will not be drawn smoothly during embroidery. Easy to damage the embroidery board. The principle of MVA (MULTI-DOMAIN VERTICAL align MENT) technology is to increase protrusions to form multiple visible areas. The liquid crystal molecules are not completely arranged vertically in a static state. After a voltage is applied, the liquid crystal molecules are arranged horizontally so that light can pass through each layer. MVA technology increases the viewing angle to over 160 degrees and provides a shorter response time than IPS and TN+FILM. This technology was developed by Fujitsu, and currently Taiwan Chi Mei (Chi Mei is a subsidiary of Chi Mei in mainland China) and Taiwan AUO are authorized to use this technology.

ViewSonic’s VX2025WM is the representative of this type of panel. The horizontal and vertical viewing angles are both 175 degrees. There is basically no visual blind angle, and it also promises no bright spots. The viewing angle is divided into parallel and vertical viewing angles. The horizontal angle is liquid crystal. The vertical axis is the center, moving left and right, you can clearly see the angle range of the image. The vertical angle is centered on the parallel central axis of the display screen, moving up and down to clearly see the angle range of the image.

We are all familiar with LCD (liquid crystal display) technology from our daily life. Your phone, your TV, your laptop all have LCD screens - the latest technology is increasing the resolution for an optimal viewing experience (HD, 4K, etc.).

Yes, of course. Similar to a DLP printer, in a LCD printer an entire layer is flashed with UV light and cured at once. But the light source is an array of LEDs exposing UV light through a LCD screen. Only the area that needs to be cured, will be exposed.

In most printers the light power of the light source changes over time - the higher the quality of the printer components, the longer you can expect the lifespan of your light source to be. A light source that does not send equally bright light through the LCD screen will inevitably cause failed prints.

With LCD technology, the build platform dips in the resin, lifts up and light shoots through the LCD panel and one layer is cured. To finish one 3D print, this happens hundreds of times.

With most slicing software you can individually set the layer thickness - the default setting is usually 100 micron. With a low value for the layer thickness, you achieve very smooth applications.

Ackuretta SOL is an exception. A 3D print made with 70 micron and one at 100 micron layer thickness showed that there"s only a 10 to 30 minute increase in printing time. Which means even the most intricate dental applications can be made same day and chairside.

In comparison, a SLA 3D printer by another manufacturer advertises the ability to produce prints with a 25 micron layer thickness but that comes at the cost of printing for over 17 hours - being highly inconvenient if you want to keep an efficient workflow.

XY Resolution and layer thickness is a central matter in 3D printing. It defines the smoothness of your prints and since dental applications are often used intraorally, they must have a natural feel to them. So you should make sure that you buy a printer that can perform accordingly.
