There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.VA
The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.10 bits
The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.1073741824 colors
The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.Edge LED
The number of special 3D eyeglasses included with the 3D TV. Some 3D TVs omit this item to control costs. Some 3D Blu-ray players may include these glasses. Retailers may offer a "3D TV + Blu-ray" bundle that also includes the glasses. All of the 3DTVs in our Ratings require the viewer to don special eyeglasses. So-called "active" 3D sets, which require "active" battery-powered LCD shutter glasses, may come with one or more pairs, or none. Additional pairs generally cost from $50 to $150 each. Most so-called "passive" 3D TVs come with four pairs of passive polarized glasses, much like the ones used in theaters, which don"t require batteries. Additional sets cost from $10 to $30 each. You cannot use passive glasses with 3DTV that requires active glasses, and vice-versa. You also generally cannot mix active 3D glasses from one brand of TV with another"s, though TVs made in 2012 and later may share glasses. (Passive 3D glasses can be used interchangeably with any passive 3D TVs.) There are some "universal" active 3D glasses you can buy as an after-market item .

Fixed-pixel display types such as LCDs and OLEDs have a native resolution. It sets an upper limit of how sharp images may look. Native resolution is expressed in horizontal by vertical pixels (for example: 1920x1080 for an HD display, 3840x2160 for UHD).
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:
LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

Compared to Samsung, LG"s LCD factory at Paju felt like a ghost town — despite housing thousands of people on-site. Of course, the sub-zero temperatures at the time probably accounted for that. It was also doubly eerie because the LCD plant is the tallest building visible from North Korea — as it"s so close to the border — and the army base built next door to protect it probably makes it even more of a target!
While televisions of one type or other have been in Australia for over 50 years, they have gone through several changes, with flat panels the latest iteration. LCD TVs have been mainstream products for about four years, but what makes them tick? This year we were fortunate enough to have visited both the Samsung and LG plants in South Korea to get a better understanding of how an LCD TV is made, and what the future holds for the technology.
Samsung is one of the world"s largest manufacturers of LCD panels, and it claims to produce one out of every four in the world. One of Samsung"s largest facilities is in Tangjeong, 80km south of Seoul. Samsung has four different plants on this site, and this is where the joint Sony/Samsung S-LCD plant was first built — and still produces Sony panels to this day. CNET Australia visited Tangjeong recently and while we not only got a squiz at the production lines, we also met with the engineers and designers who helped make them possible.
The Tangjeong factory is a large facility south of Seoul, and produces panels for the five-year-old S-LCD collaboration between Sony and Samsung. As a result of this union, Sony owns part of the production lines on the Tangjeong site — this equates to 50 per cent of the L7-1 line, plus half of the combined L8 (1 and 2) lines. The L8-2 factory has only come online in the last month.
Samsung has begun planning its ninth plant, which will produce its Generation 11 panels (L9), and this will fit in behind the two existing factories. It will be capable of producing much larger panels than the L8 plant with 40, 62 and 72 inches possible.
We got to see one of the L7 (no relation to the LA-based band) lines in operation, after donning the fetching blue shoe covers. Unfortunately, we were unable to take photos inside the LCD factory, as apparently corporate espionage is a big problem. However, we"ll do our best to explain the long corridor with its helpful blue signs and series of LCD panels in various states of undress explaining each part of the process.
There were several different "lines" in each factory — each doing a different sized panel. Apparently it takes three days to convert one line to produce another size, so there is some redundancy built into the system to cover for any downtime.
A promotional image of a quantum-dot LED TV (Samsung Electronics)Samsung Display, the display making arm of Samsung Electronics, is poised to fully shut down its unprofitable liquid crystal display panel business for televisions in June, after over 30 years of operation.
“(Samsung Display) will terminate its supply of LCD panels in June,” an industry source said Monday. The company has been manufacturing its lower-end panels in Asan, South Chungcheong Province.
The long-awaited move came as LCD TV panel prices have been on a constant decline. This led to greater losses for Samsung Display, while Chinese competitors have been ramping up their dominance in the global industry supported by state subsidies and tax breaks.
LCD TVs are considered lower-end when compared to those using cutting-edge TV components such as organic light-emitting diode panels and quantum dot display panels.
According to market intelligence firm Omdia‘s estimate compiled by Daishin Securities, 43-inch LCD panel prices fell 46 percent from September 2021 to May this year, while that of 55-inch panels and 65-inch panels both declined 34 percent over the cited period.
This marks the end of Samsung’s three-decade LCD TV panel business. Once the largest LCD TV panel supplier in the world, Samsung Display‘s market share has gradually shrunk from 22 percent in 2014 to around 2 percent this year.
Samsung Display had sought to exit the business from before 2021, but has been hanging on in part due to Samsung Electronics’ LCD panel supply shortage.
Choi Kwon-young, executive vice president of Samsung Display, confirmed the company’s full exit from the LCD TV panel business within this year in a first-quarter conference call in April.
Given that Samsung’s LCD TV panel exit has long been anticipated and carried out gradually, Samsung Electronics will “unlikely be affected by Samsung Display‘s LCD panel exit” in terms of its continuity in the LCD TV set business, noted Kim Hyun-soo, an analyst at Hana Financial Investment on Monday.
Samsung looks to pivot to quantum dot display technologies for its TV panel business, using quantum dot light-emitting diodes or quantum dot organic light-emitting diodes.
As for the anticipated collaboration between TV maker Samsung Electronics and the world‘s sole white-OLED TV panel supplier LG Display, Kim of Hana said the launch of Samsung’s OLED TV is unlikely within this year due to prolonged negotiations.
The decision to close the LCD business, by Samsung Display, will be completed by June of 2022 as the company faces tough competition from its Chinese and Taiwanese counterparts, reports GizmoChina.
The company has decided to focus on manufacturing organic light-emitting diode (OLED) and quantum dot (QD) displays, as OLED panels have started to become the norm in the smartphone market.
A recent Display Supply Chain Consultants (DSCC) revealed that the price of an LCD is 36.6 per cent of what it used to be in January 2014, the component"s peak production period.
No investment plan details have since been announced, and the employees of the LCD business are expected to be transferred to the QD business, the report said.
Samsung Display had decided to close its LCD business in late 2020, but the plans were delayed at Samsung Electronics" request due to a sudden increase in the prices of LCD panels during the Covid-19 pandemic.
Samsung Display will stop producing LCD panels by the end of the year. The display maker currently runs two LCD production lines in South Korea and two in China, according to Reuters. Samsung tells The Verge that the decision will accelerate the company’s move towards quantum dot displays, while ZDNetreports that its future quantum dot TVs will use OLED rather than LCD panels.
The decision comes as LCD panel prices are said to be falling worldwide. Last year, Nikkei reported that Chinese competitors are ramping up production of LCD screens, even as demand for TVs weakens globally. Samsung Display isn’t the only manufacturer to have closed down LCD production lines. LG Display announced it would be ending LCD production in South Korea by the end of the 2020 as well.
Last October Samsung Display announced a five-year 13.1 trillion won (around $10.7 billion) investment in quantum dot technology for its upcoming TVs, as it shifts production away from LCDs. However, Samsung’s existing quantum dot or QLED TVs still use LCD panels behind their quantum dot layer. Samsung is also working on developing self-emissive quantum-dot diodes, which would remove the need for a separate layer.
Samsung’s investment in OLED TVs has also been reported by The Elec. The company is no stranger to OLED technology for handhelds, but it exited the large OLED panel market half a decade ago, allowing rival LG Display to dominate ever since.
Although Samsung Display says that it will be able to continue supplying its existing LCD orders through the end of the year, there are questions about what Samsung Electronics, the largest TV manufacturer in the world, will use in its LCD TVs going forward. Samsung told The Vergethat it does not expect the shutdown to affect its LCD-based QLED TV lineup. So for the near-term, nothing changes.
One alternative is that Samsung buys its LCD panels from suppliers like TCL-owned CSOT and AUO, which already supply panels for Samsung TVs. Last year The Elec reported that Samsung could close all its South Korean LCD production lines, and make up the difference with panels bought from Chinese manufacturers like CSOT, which Samsung Display has invested in.
In 1991, a business unit called Samsung Display was formed to produce the panels used in products made by its parent company, Samsung Electronics. Afterward, it was a leading supplier of LCD panels not just for Samsung Electronics but for other companies in the industry as well.
The business received a stay of execution when the pandemic led to a global surge in demand for consumer electronics, but that demand is now declining, and projections aren"t good for LCD panel revenue.
Add to that the fact that emerging technologies like QD-OLED are the future for TV and monitors, and the case for keeping Samsung Display"s LCD business going becomes a hard one to make.
Samsung Display will now focus heavily on OLED and quantum dot. Most of the employees working in the LCD business will move to quantum dot, the publication claims.
Even if there isn"t a statement about a change in direction, the writing has been on the wall for Samsung"s LCD business. Unless something radical changes, it"s more a question of when than if at this point.
