Thin-Film Transistor Liquid Crystal Displays use thin-film transistors to control the voltage applied to the liquid crystal layer at a sub-pixel level. The structure of TFT LCDs consists of a TFT “sandwich” and a BLU (Backlight Unit). A typical configuration is shown in the schematic diagram below.

Firstly, between the back and front polarizers, TFT LCD cells are made with two glass substrates – one for color filters, the other for a TFT array – and a liquid crystal layer sandwiched in between.

For normally black TFT LCDs, if we follow along a piece of light setting off from its backlight source, it will bea)guided uniformly by LGP;b)reflected and enhanced by BEF and DBEF;c)polarized by the back polarizer;d)polarization changed by twisted LC under the voltage applied by TFT arrays;e)“tinted” red/green/blue by corresponding color filter of the subpixel;f)let through the front polarizer by matched polarization; andg)finally, it will reach the surface and appears in viewer’s eyes.

For normally white panels, processd)will be the opposite – known as the polarization rotation effect, light is twisted in a voltage-off stage and can pass through the front polarizer by default, thus displaying white normally. However, when the voltage applied increases, this polarization rotation effect would be gradually diminished. And the light would not be able to pass through the front polarizer anymore without changing its polarization. In this way, certain pixels will appear in different colors.

Normally black LCDs have higher contrast and wider viewing angles without grayscale inversion phenomenon compared to their normally white relatives. And whether TFT LCDs are normally black or white depends on their LC switching mode:

As previously mentioned, TN mode functions with the polarization rotation effect. Under traditional TN/VA display mode, the liquid crystal molecules are vertically arranged, with a relatively narrow visual angle. When an external force is exerted on the screen, the liquid crystal molecular structure will sink in a herringbone pattern to slowly recover – a pattern called vertical alignment. Therefore, an evident “water ripple” usually appears when the display surface is touched and impacts the user experience. In comparison, the VA mode provides higher contrast. And MVA (multi-domain vertical alignment) is an upgraded version of VA with improved viewing angles.

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

We have some updates from one of the smaller LCD panel manufacturers BOE about their panel development plans. This is BOE as a panel manufacturer, as opposed to any specific monitor/display manufacturer, but it gives an indication of where monitors are likely to go in the future by looking ahead at the panel production plans. Please keep in mind that the production dates are not set in stone and may change, and there is then also a lag of several months before a panel is produced, then used in a display and launched to market. We have updated our panel parts database with all the new information we have as well as best we can.

A lot of the information we have focused on technology improvements in general, and there is less specific information about actual panels and their specs than we have from other manufacturers. We will try and summarise as best we can. BOE are focusing their panel development and investment on several key themes:

One area BOE are developing is the use of a new “OQD” film (we believe this stands for Oxide Quantum Dot). They report that this has a few advantages over traditional QD coatings including being toxic element-free (QD contains Cd/Se apparently), has an improved light efficiency (~90% vs ~70%), no edge degradation and offers the same kind of benefits with wide colour gamut boosting it up to around 170% sRGB.

BOE should already have panel options in production now offering 99% coverage of DCI-P3 and Adobe RGB spaces, as well as 83% BT.2020. There are a couple of 27″ sized panels (panel tech not listed but we expect this to be their ADS technology, IPS-type) with 3840 x 2160 resolution which feature this OQD coating and the above mentioned colour space coverage. One with a 300 cd/m2 brightness in mass production since Sept 2020 and the other which has a slightly boosted brightness of 400 cd/m2 which should have been tested now and hopefully in production also.

BOE also aim to boost this colour gamut a little further in Q1 2021 with coverage up to 90% BT.2020. They are planning a 31.5″ sized panel (tech not listed but again expected to be IPS-type) with 3840 x 2160 resolution and 350 cd/m2 brightness, but no forecast on production dates yet.

BOE are also focusing on developing new panel options with more local dimming zones for improved HDR experiences in the desktop monitor space. There are several Mini LED backlight options being developed. These include

BOE are also focusing on new technologies to enhance the HDR experience further than Mini LED backlights, with even more finite control of the dimming zones and in an effort to compete with the ever-popular OLED technology in this space. One such development is in their BD Cell technology. The following comes from a May 2020 BOE press release talking about BD Cell usage for their 65″ panel which win a SID 2020 Display Industry award, telling us more about what this technology can offer:

As a breakthrough in thin-film transistor (TFT)-LCD technology, BOE’s dual-cell panel—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 can raise 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.

BOE have two panels in their plans featuring BD Cell technology. The first listed in their plans as BD Cell doesn’t seem to really offer any of the benefits talked about above and is a 23.8″ sized panel with 1920 x 1080 resolution but is listed with an “edge type” backlight system . We are not sure how that fits in with the above description which talks about pixel level backlight control, but this looks to be more like a traditional edge lit local dimming option than any direct lit backlight type and so might not really offer anything significant. There is a >300,000:1 contrast ratio listed, but the screen has only a normal 8-bit colour depth, 350 cd/m2 brightness and standard sRGB gamut (72% NTSC coverage). This is expected to go in to production in Nov 2020.

BOE also have a focus on improving their panel options for gaming screens with their ADS (IPS-type) technology. Already in mass production are a range of panels in sizes of 23.8″, 27″ and 34″ with 144 and 165Hz refresh rates. They are now developing 240Hz versions of the smaller models with the 23.8″ version due to go in to production this month, and the 27″ version which was due to go in to production in Sept. Both are only 1920 x 1080 resolution though.

There’s still a portion of the market who prefer 16:10 aspect ratio screens to common 16:9 offerings. This has commonly been in the 24″ space with 1920 x 1200 resolutions in 16:10 format offering a bit of a vertical boost compared with the common 1920 x 1080 resolutions of the 16:9 format. BOE are still investing in this area with a new 24″ panel planned but this time with a higher 2560 x 1600 resolution. This works out as 125 PPI and the panel also offers a 1000:1 contrast ratio, 350 cd/m2 brightness and 95% DCI-P3 gamut. Production dates are not listed.

The display model YF080B01 is a IPS TFT-LCD(Thin film transistor liquid crystal display)module. This model is Composed of a TFT LCD panel, a driving circuit and a back light, and also has a 8.0 inch diagonally measured active display area with 800 horizontal by 1280 vertical pixel resolution in a stripe arrangement. Display 16M colors by 8 bit R.G.B signal input.
