Typical LCDs are edge-lit by a strip of white LEDs. The 2D backlighting system in Pro Display XDR is unlike any other. It uses a superbright array of 576 blue LEDs that allows for unmatched light control compared with white LEDs. Twelve controllers rapidly modulate each LED so that areas of the screen can be incredibly bright while other areas are incredibly dark. All of this produces an extraordinary contrast that’s the foundation for XDR.

For even greater control of light, each LED is treated with a reflective layer, a highly customized lens, and a geometrically optimized reflector that are all unique to Pro Display XDR. Through a pioneering design, light is reflected, mixed, and shaped between two layers to minimize blooming and provide uniform lighting.

Converting blue light to white is a difficult process that requires extremely precise color conversion. It’s why most display makers use white LEDs. Pro Display XDR accomplishes this conversion with an expertly designed color transformation sheet made of hundreds of layers that control the light spectrum passing through them.

With a massive amount of processing power, the timing controller (TCON) chip utilizes an algorithm specifically created to analyze and reproduce images. It controls LEDs at over 10 times the refresh rate of the LCD itself, reducing latency and blooming. It’s capable of multiple refresh rates for amazingly smooth playback. Managing both the LED array and LCD pixels, the TCON precisely directs light and color to bring your work to life with stunning accuracy.

To create an LCD, you take two pieces ofpolarized glass. A special polymer that creates microscopic grooves in the surface is rubbed on the side of the glass that does not have the polarizing film on it. The grooves must be in the same direction as the polarizing film. You then add a coating of nematic liquid crystals to one of the filters. The grooves will cause the first layer of molecules to align with the filter"s orientation. Then add the second piece of glass with the polarizing film at a right angle to the first piece. Each successive layer of TN molecules will gradually twist until the uppermost layer is at a 90-degree angle to the bottom, matching the polarized glass filters.

If we apply an electric charge to liquid crystal molecules, they untwist. When they straighten out, they change the angle of the light passing through them so that it no longer matches the angle of the top polarizing filter. Consequently, no light can pass through that area of the LCD, which makes that area darker than the surrounding areas.

Building a simple LCD is easier than you think. Your start with the sandwich of glass and liquid crystals described above and add two transparent electrodes to it. For example, imagine that you want to create the simplest possible LCD with just a single rectangular electrode on it. The layers would look like this:

The LCD needed to do this job is very basic. It has a mirror (A) in back, which makes it reflective. Then, we add a piece of glass (B) with a polarizing film on the bottom side, and a common electrode plane (C) made of indium-tin oxide on top. A common electrode plane covers the entire area of the LCD. Above that is the layer of liquid crystal substance (D). Next comes another piece of glass (E) with an electrode in the shape of the rectangle on the bottom and, on top, another polarizing film (F), at a right angle to the first one.

The electrode is hooked up to a power source like a battery. When there is no current, light entering through the front of the LCD will simply hit the mirror and bounce right back out. But when the battery supplies current to the electrodes, the liquid crystals between the common-plane electrode and the electrode shaped like a rectangle untwist and block the light in that region from passing through. That makes the LCD show the rectangle as a black area.

lcd panel (Liquid crystal display) are made of liquid crystals that form digital images made visible through ambient light or through LED backlight. LCDs are used in the place of other displays that are less efficient such as cathode ray tubes (CRTs) and have become the most popular display type on the market.

For volumetric 3D display technologies, we will review static screen (solid-state upconversion, gas medium, voxel array, layered LCD stack, and crystal cube) and swept screen (rotating LED array, cathode ray sphere, varifocal mirror, rotating helix, and rotating flat screen). Both passive screens (no emitter) and active screens (with emitters on the screen) are discussed.

Conventional 2D display devices, such as cathode ray tubes (CRTs), liquid crystal devices (LCDs), or plasma screens, often lead to ambiguity and confusion in high-dimensional data/graphics presentation due to lack of true depth cues. Even with the help of powerful 3D rendering software, complex data patterns or 3D objects displayed on 2D screens are still unable to provide spatial relationships or depth information correctly and effectively. Lack of true 3D display often jeopardizes our ability to truthfully visualize high-dimensional data that are frequently encountered in advanced scientific computing, computer aided design (CAD), medical imaging, and many other disciplines. Essentially, a 2D display apparatus must rely on humans’ ability to piece together a 3D representation of images. Despite the impressive mental capability of the human visual system, its visual perception is not reliable if certain depth cues are missing.

In the following sections, we will provide brief discussions on each technique listed in Fig. 8. We try to highlight the key innovative concept(s) in each opto-electro-mechanical design and to provide meaningful graphic illustration, without getting bogged down in too much technical detail. It is our hope that readers with a general background in optics, computer graphics, computer vision, or other various 3D application fields can gain a sense of the landscape in the 3D display field and benefit from this comprehensive yet concise presentation when they carry out their tasks in 3D display system design and applications.

Shopping for a new TV is like wading through a never-ending pool of tech jargon, display terminology, and head-spinning acronyms. It was one thing when 4K resolution landed in the homes of consumers, with TV brands touting the new UHD viewing spec as a major marketing grab. But over the last several years, the plot has only continued to thicken when it comes to three- and four-letter acronyms with the introduction of state-of-the-art lighting and screen technology. But between OLEDs, QLEDs, mini-LEDs, and now QD-OLEDs, there’s one battle of words that rests at the core of TV vocabulary: LED versus LCD.

Despite having a different acronym, LED TV is just a specific type of LCD TV, which uses a liquid crystal display (LCD) panel to control where light is displayed on your screen. These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to align, so that light can (or can’t) pass through. Think of it as a shutter, either allowing light to pass through or blocking it out.

Since both LED and LCD TVs are based around LCD technology, the question remains: what is the difference? Actually, it’s about what the difference was. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.

Since the technology is better, all LCD TVs now use LED lights and are colloquially considered LED TVs. For those interested, we’ll go deeper into backlighting below, or you can move onto the Local Dimming section.

Three basic illumination forms have been used in LCD TVs: CCFL backlighting, full-array LED backlighting, and LED edge lighting. Each of these illumination technologies is different from one another in important ways. Let’s dig into each.

CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. This affects some aspects of picture quality, which we discuss in more detail below. Since CCFLs are larger than LED arrays, CCFL-based LCD TVs are thicker than LED-backlit LCD TVs.

Full-array backlighting swaps the outdated CCFLs for an array of LEDs spanning the back of the screen, comprising zones of LEDs that can be lit or dimmed in a process called local dimming. TVs using full-array LED backlighting to make up a healthy chunk of the high-end LED TV market, and with good reason — with more precise and even illumination, they can create better picture quality than CCFL LCD TVs were ever able to achieve, with better energy efficiency to boot.

Another form of LCD screen illumination is LED edge lighting. As the name implies, edge-lit TVs have LEDs along the edges of a screen. There are a few different configurations, including LEDs along just the bottom, LEDs on the top and bottom, LEDs left and right, and LEDs along all four edges. These different configurations result in picture quality differences, but the overall brightness capabilities still exceed what CCFL LCD TVs could achieve. While there are some drawbacks to edge lighting compared to full-array or direct backlight displays, the upshot is edge lighting that allows manufacturers to make thinner TVs that cost less to manufacture.

To better close the local-dimming quality gap between edge-lit TVs and full-array back-lit TVs, manufacturers like Sony and Samsung developed their own advanced edge lighting forms. Sony’s technology is known as “Slim Backlight Master Drive,” while Samsung has “Infinite Array” employed in its line of QLED TVs. These keep the slim form factor achievable through edge-lit design and local dimming quality more on par with full-array backlighting.

Local dimming is a feature of LED LCD TVs wherein the LED light source behind the LCD is dimmed and illuminated to match what the picture demands. LCDs can’t completely prevent light from passing through, even during dark scenes, so dimming the light source itself aids in creating deeper blacks and more impressive contrast in the picture. This is accomplished by selectively dimming the LEDs when that particular part of the picture — or region — is intended to be dark.

Local dimming helps LED/LCD TVs more closely match the quality of modern OLED displays, which feature better contrast levels by their nature — something CCFL LCD TVs couldn’t do. The quality of local dimming varies depending on which type of backlighting your LCD uses, how many individual zones of backlighting are employed, and the quality of the processing. Here’s an overview of how effective local dimming is on each type of LCD TV.

TVs with full-array backlighting have the most accurate local dimming and therefore tend to offer the best contrast. Since an array of LEDs spans the entire back of the LCD screen, regions can generally be dimmed with more finesse than on edge-lit TVs, and brightness tends to be uniform across the entire screen. Hisense’s impressive U7G TVs are great examples of relatively affordable models that use multiple-zone, full-array backlighting with local dimming.

Because edge lighting employs LEDs positioned on the edge or edges of the screen to project light across the back of the LCD screen, as opposed to coming from directly behind it, it can result in very subtle blocks or bands of lighter pixels within or around areas that should be dark. The local dimming of edge-lit TVs can sometimes result in some murkiness in dark areas compared with full-array LED TVs. It should also be noted that not all LED edge-lit TVs offer local dimming, which is why it is not uncommon to see glowing strips of light at the edges of a TV and less brightness toward the center of the screen.

Since CCFL backlit TVs do not use LEDs, models with this lighting style do not have dimming abilities. Instead, the LCD panel of CCFL LCDs is constantly and evenly illuminated, making a noticeable difference in picture quality compared to LED LCDs. This is especially noticeable in scenes with high contrast, as the dark portions of the picture may appear too bright or washed out. When watching in a well-lit room, it’s easier to ignore or miss the difference, but in a dark room, it will be, well, glaring.

An OLED display uses a panel of pixel-sized organic compounds that respond to electricity. Since each tiny pixel (millions of which are present in modern displays) can be turned on or off individually, OLED displays are called “emissive” displays (meaning they require no backlight). They offer incredibly deep contrast ratios and better per-pixel accuracy than any other display type on the market.

Because they don’t require a separate light source, OLED displays are also amazingly thin — often just a few millimeters. OLED panels are often found on high-end TVs in place of LED/LCD technology, but that doesn’t mean that LED/LCDs aren’t without their own premium technology.

QLED is a premium tier of LED/LCD TVs from Samsung. Unlike OLED displays, QLED is not a so-called emissive display technology (lights still illuminate QLED pixels from behind). However, QLED TVs feature an updated illumination technology over regular LED LCDs in the form of Quantum Dot material (hence the “Q” in QLED), which raises overall efficiency and brightness. This translates to better, brighter grayscale and color and enhances HDR (High Dynamic Range) abilities.

And now to make things extra confusing, part of Samsung’s 2022 TV lineup is being billed as traditional OLEDs, although a deeper dive will reveal this is actually the company’s first foray into a new panel technology altogether called QD-OLED.

In order to choose the best monitor for your needs, it is very important to distinguish what kind of LCD panel interface type is in the monitor you’re looking at. The most common panels used nowadays are;

One of the types of panels that you will find in a computer monitor is a TN Panel. This stands for Twisted Nematic, and this particular type of LCD panel is generally the cheapest. They are the cheapest to manufacture among all LCD technologies, so they are the most commonly used in budget monitors.

If you are looking to game online, you will need a monitor with a higher refresh rate like that offered by a TN panel. Refresh rates are measured in Hertz (Hz), which defines how many times per second your screen can display new images.

The typical response time for a TN panel is less than 5 ms which is much faster than the 6 or 8 ms response time that other LCD displays have, such as vertical alignment or VA.

The biggest downside with these panels is often their viewing angles. On a TN panel, the viewing angles aren"t very good, and depending on how far off-center you are, the picture can begin to lose color and contrast.

TN panels also don"t support as wide a range of resolutions as IPS. This LCD monitor panel type has a poor contrast ratio when compared with other technologies such as IPS and VA. This results in an inability to display deep blacks and bright whites at the same time.

TN panels are manufactured by Samsung, LG, AUO, Chi-Mei, Chunghwa Picture Tubes, Hannstar Display Corporation, Sharp Corporation, CMI, Innolux, J-Tech Digital Imaging Co. Ltd, AU Optronics Corporation, etc.

A TN panel is a type of liquid crystal display (LCD) used in most LCD monitors and laptops. TN panels were the workhorse of the 1990s and early 2000s, but they were eventually replaced by their more-expensive cousins, the in-plane switching (IPS) and vertical alignment (VA) panels.

TN computer panels work by using two polarized filters, vertical and horizontal, to control the light that passes through them. The filters are arranged so that when the electrical current is off, light cannot pass through. When it"s on, it hits the twisted crystals to produce colors. The active layer is twisted to allow the light to pass through it, and this twist is controlled by electrical fields applied to the liquid crystal material.

It is worth noting that A TN panel is made up of millions of pixels, each pixel being red, green, or blue in color. The light from each pixel can be either on or off, so black is created when all the pixels are off and white when all are on. When all three colors are combined, any color can be produced. This arrangement is called RGB (red-green-blue).

A TN panel uses twisted nematic liquid crystals to form images. While not as desirable as other technologies, it does have several benefits worth considering when making a purchasing decision.They are mostly found in budget LCDs, as they are cheaper to manufacture and therefore sell for less.

TN panels have excellent response rates and refresh rates, typically 1 - 2 milliseconds and 50 – 75 Hz, respectively. This makes them ideal for high-end gaming

TN is the oldest and most common type of LCD panel, and it"s also the cheapest to produce. TN panels were the first panels to be introduced to the market, but they"re no longer as popular as they used to be. This is because TN panels have several downsides:The main disadvantage of TN panels is limited viewing angles, which can be extremely limiting in some cases. If you"re sitting straight in front of the monitor, everything is fine, but if you move to the side, then all colors shift and get distorted. That can be extremely annoying for graphic designers or architectswho work with color palettes, photographers who need exact color matching, etc. (see also

TN panels typically have lower contrast ratios than IPS displays do, so they don"t look as rich in color or dark black. So TN panels are usually not suitable for professional applications such as color-critical photo editingand graphic design.

Many gamers prefer TN panels because they provide a very fast response time and higher refresh rates. You can also find some with a refresh rate of 240Hz, which is even better.The Asus VG248QE is a 24-inch LCD display with a 1920 x 1080 resolution and a 1ms response time. It uses a TN panel, so don"t expect much in terms of viewing angle or color reproduction accuracy compared to an IPS display. But if you"re looking for a good 144Hz monitor, choose this one.

ViewSonic VX2458-MHD. It has a TN panel. The refresh rate of this monitor is 72Hz, which is standard. The response time of this monitor is 1ms. It also comes with 4 USB 3.0 ports, which is great if you plan on hooking up multiple devices, which is frequently used when trading. If you have a setup like that, you will also want to look at bezel less monitors, or frameless monitors, for your needs.

Another common type of panel is a VA panel. This stands for Vertical Alignment and is a step above a TN panel in terms of quality. Its name comes from the fact that light emitted from the screen"s backlight (see also LED monitors) is aligned vertically rather than being scattered horizontally and vertically as it is with a TN display.

VA panels provide high-quality images, wide viewing angles along with excellent contrast ratio and high refresh rates. These factors make VA panel monitors preferred for graphic design, photographers, video editors, and others who often work on their PCs.

VA panels are also better when displaying fast-moving images because they offer high refresh rates hence have less motion blur. Additionally, some panels have support for even 120 Hz refresh rates for ultra-smooth movement in games and movies.

Traditional LCD displays use two polarizing filters and liquid crystals (LCs) to create all the colors and patterns that we see on computer monitors and flat-panel televisions.

What are the Benefits of VA Panels?Image quality of VA technology is considered better than TN technology; text appears crisper, and images appear sharper and richer in contrast and color.

The big downside of TN panels is their response time. Most TN panels have a response time of 5-8 MS, which is fine for most people. However, if you"re mostly into competitive gaming or fast-paced action games like me that require quick reflexes, then this could be a problem.

We did some research and came up with a list of the best monitors with VA panels, and they are;ViewSonic VX2457-MHD. It is a24-inch monitor with a 1920 x 1080 resolution and covers 100% of the sRGB spectrum. It also has plenty of picture-enhancing features, including adjustable color settings and support for AMD"s FreeSync technology (see also affordable G Sync monitors).

This is the best LCD panel type. IPS stands for In-Plane Switching, and the biggest advantage over the other panels listed above is its wide viewing angles.

These screens are more expensive than TN panels but offer a greater contrast ratio, higher resolutions than their TN counterparts. They also support higher refresh rates, lower response time which makes them ideal for monitors larger than 24 inches.

These panels offer much more consistent colors, which makes them ideal for graphic designers or anyone who does any kind of color-critical work on their monitor.

IPS panels offer wider viewing angles than VA panels do, making them better suited for use in public spaces such as retail stores or airports where you can expect people will be walking by your TV from both sides.

The contrast ratio of an IPS panel is higher than that of TN panels. The contrast ratio of a display refers to the difference between the darkest black and the brightest white that the display is capable of producing. This can be an important factor in overall display quality, depending on how you use your laptop or desktop monitor.

Some manufacturers that specialize in IPS panel interphases include Samsung, LG, and even Mac Apple. Also, almost all Dell monitors use IPS panels. However, there are plenty of other high-quality manufacturers that also offer IPS panels for you to choose from.

In a liquid crystal display (LCD), light passes through a pair of polarizers. Each polarizer is made of a long chain of molecules, each oriented in a different direction; one vertical, the other horizontal.

In an IPS LCD panel, liquid crystals are aligned so that both polarizers face the same way—horizontal. Light from behind the panel passes through one polarizer and then bounces off onto a second polarizer before reaching your eyes. This design makes IPS LCDs nearly as bright as VA panels and much brighter than TN panels without sacrificing contrast ratio or color accuracy.

If you"re looking for a new monitor, IPS panels may be the right ones for you. Here are some of their most important benefits:It allows for wider viewing angles. This is very useful for monitors used at work that involve customer service, where the monitor may be viewed from many different angles.

The IPS LCD displays are also characterized by their high degree of brightness and contrast, which makes them ideal for outdoor use, among many other features.

The typical lifespan of an IPS panel is around 100,000 hours, which is more than enough for even heavy users to get their money"s worth from their monitor.

They have great color reproduction. Many people who are serious about a photo or video editing are drawn to IPS panels because they offer superior color reproduction possibilities when compared with TN panels.

The main disadvantage of IPS panels is that they are more expensive than TN panels. The cost of an IPS panel will typically be $10-$20 higher than a comparable TN panel.

Today, the majority of flat-panel monitors use in-plane switching (IPS) technology. Best monitors that have IPS panels include;Samsung U28E590D 28-Inch 4K UHD Monitor. If you love gaming, then this is the product for you; it comes with AMD FreeSync, which proved successful in eliminating screen tearing since being introduced as VSync, as this post explained.

Also, bear in mind that if it is a flat panel display with a 1080p resolution or higher, you can refurbish it and resell it after using it. Older monitors with lower resolutions may not be worth much.

It offers a much higher resolution than conventional LCD and can be used to manufacture large panels. It"s an innovative display technology that has the potential to change the face of consumer electronics.

There are 3 main types of LCDs; VA (Vertical Alignment), TN (Twisted Nematic), and IPS (In-Plane Switching). All these technologies have been used for over 10 years and have their own pros and cons. However, they have reached their upper limits in terms of resolution and other features, and it"s nearly impossible to increase them any further. That"s where Super PLS-Plane to Line Switching comes in.

Super PLS-Plane to Line Switching offers resolutions as high as 8K, has wider viewing angles, and is brighter. The image quality presented by this technology is said to be much better than traditional LCDs, and it could potentially disrupt the current.

The Nano IPS panel technology adds a layer of nano-particles to the backlight in order to transmit the screen"s picture more efficiently and reduce the chances of image retention.

Advanced Hyper-Viewing Angle (AHVA) computer display was developed by AU Optronics Corp. It is a type of LCD that can be seen clearly even from the most acute angles. Through the process of strengthening the polarizing plate, it can help minimize the reflection ratio to less than 1%. The viewing angle is about 178 degrees.

Most LCDs (liquid crystal display) monitors are now manufactured with an anti-glare coating to reduce the effect of ambient light reflecting off the screen. Anti-glare coatings can reduce reflections by 25 to 70%.

VA panel is better thank IPS. Although IPS panels have a contrast ratio of 700:1 to 1500:1, they are still inferior to VA panels. The majority of VA monitor panels have contrast ratios above 2500:1, and some even reach 5000:1 or 6000:1. Even local dimming is used by more recent monitors to obtain even greater contrast ratios.

Yes, IPS is better than OLED. The main benefit of IPS panels is their increased brightness, particularly when combined with a tiny LED backlight. OLED displays are often limited to brightness levels of roughly 1,000 nits, while mini LED displays can reach peak brightness levels of around 2,000 nits.

Different displays use different types of TCONs. In this article we will be talking about TCONs for the IT market: LCD (Liquid Crystal Display) notebook PCs and monitors.

An LCD panel has millions of Red, Green, and Blue (RGB) liquid crystals that are used to block a white backlight when electrical voltage is applied to them. High voltage signals to each individual pixel control how much of the backlight to block. A white display means nothing is being blocked. A black display means all three colors are blocked at maximum effort.

TCONS direct the high voltage driver chips that move the color filters and are usually found on a circuit board that sits below the glass panel (Fig. 1).

eDP connections are fast, use few wires, and are flexible for size, bandwidth and adding features eDP provides all panel connections in one plug, including power, data, and control signals. This is Analogix’s specialty.

While the GPU is responsible for transforming mathematical equations into individual pixels and frames, a TCON takes the individual frames generated by the GPU, corrects for color and brightness, then sends out parts of the image to each individual driver at the panel’s specific timing.

The human eye has an incredible dynamic range.  That means we can see both very dark images and very bright images, at the same time. However, neither camera sensors nor display panels can display that range. Your camera generates HDR images by using images from multiple exposures to combine the brightest and darkest parts of the picture. This increases the contrast (dynamic range) between light and dark, pulling out details from darkened or washed out areas.

HDR accurately maps real world color and luminance to a display panel. VESA DisplayHDR™ standard specifies HDR quality, including luminance, color gamut, bit depth, and rise time.

Display panels have difficulty displaying a wide range of brightness. Normal sunlight can reach 10,000 nits, but the backlight on most notebooks today is around 250 nits

VESA DisplayHDR requires the panel to meet minimum brightness, contrast, and color. No panel can reach 10,000nits of natural light. The brightest a 250nit notebook panel can produce is 250nits and any image above 250nits is washed out.  Also, no details from 250 nits to 10,000nits can be seen.

The HDR400 specifications require a dimmable backlight which helps with both producing darker blacks and lowering the power consumption. Tone mapping is used to map the whole range of 10,000 nits down to what the panel can handle, so the details can be seen. Tone mapping does not increase the brightness of the panel; it only makes the details visible.

VESA DisplayHDR600 Requires local dimming. No LCD panel can reach the VESA DisplayHDR600 requirement of 6000:1 contrast ratio. However, this can be overcome with local dimming.

For example, a 750:1 contrast panel requires 8 different backlight power settings to reach 6000:1 contrast ratio. However, unless there are thousands of separate regions, local dimming always produces halos around the bright areas. In order to reduce the halos, the following are recommended:

Monitors can use a direct backlight with many regions. An extra layer of liquid crystal can be used to dim the backlight at a specific location but this often results in a panel that is too thick for a notebook.

Notebook backlights use LEDs on the edge of the panel to reduce panel thickness. These can be on 1 side, 2 sides, or all 4 sides. Each edge adds to cost and bezel size.

Global Dimming Power Savings - Figure 6 shows a 15.6” UHD panel with 400nit maximum brightness. Figure 7 shows a comparison of backlight power consumption values between 400nit, 50nit and, respectively 5nit.

The primary goal of color management is to obtain a good match across color devices; for example, the colors of one frame of a video should appear the same on a computer LCD monitor, on a TV screen, and as a printed poster. Color management helps to achieve the same appearance on all of these devices, provided the devices are capable of delivering the needed color intensities. Color management cannot guarantee identical color reproduction, as this is rarely possible, but it can at least give more control over any changes which may occur.

A PC in HDR and SDR modes use different color gamut but the same screen. Dual-panel phones and notebooks need the color of the two sides to match perfectly. Graphic artists for web sites, movies, video games, etc., need to know what they are creating looks the same on their screen as on their customers’ screens.

As panels improve, the color space of new panels may exceed the color space from Windows.  This results in displays which look oversaturated. There is a trend towards low blue light or “night shift” panels, while still retaining color accuracy for the other colors. Today, low blue light panels are created by measuring each individual panel, then hoping that the yield is high enough.

Analogix’s Advanced Color Blocking (ACB) technology is used to create consistent image quality across different panels and change color space for different usage modes (Fig. 8). It allows for 3D color gamut rotation in the optical color domain rather than the RGB domain and color space change on the fly, such as color mapping of BT.2020 source to sRGB or DCI-P3 panels. It includes LUT shadow registers and hardware transition calculations (to smooth changes).

Color conversion in the TCON can dynamically and continuously adjust the incoming signal from the GPU for a low blue light color space. This way, no individual panel measurement is needed and yields should increase. While this can also be done by the GPU itself, that takes GPU bandwidth and 500x more power.

Panel Self-Refresh (PSR) – frame buffer in a TCON can maintain a display image without receiving video data from the CPU. For a still image, this allows the GPU to enter a low-power state and the eDP main link to turn off. Allowing the GPU to power down between display updates will save significant power and extend battery life.

Panel Self-Refresh with Selective Update (PSR2) is a superset of the panel self-refresh feature and it allows the transmission of modified areas within a video frame with obvious benefits when watching a movie or playing a game. PSR2 identifies when only a portion of the screen is static, which is a selective update. In PSR2, when the full screen is static, the refresh rate can be lowered for further power savings as done by Intel Low Refresh Rate (LRR). Intel LRR lowers the refresh rate by changing pixel clock or by changing vertical blank depending on the scenario such as idle, playing video, browsing, etc. All Analogix TCONs support Intel LRR.

In-Cell Touch embeds the touch function in the display itself, the panel including all the touch sensors, controllers, and needed processing. This simplifies the production process and reduces weight and reflection by removing the cover glass. It also allows for thinner bezels as there is no need for daughter cards and no separate wires for touch, as well as lighter devices as the cover glass is removed.

Analogix has pioneered the in-cell touch notebook panel TCONs. About 15% of notebooks support touch and we expect the touch attach rate to increase as more active pen support is introduced.
