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.

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.

Among the world famous brands, the screen of South Korea"s samsung and LG is known to be produced and sold by themselves.Display screens of other niche brands, and those brands capable of self-production and self-marketing, also have an unassailable position in their own segments, facing various brands.For buyers, how to find suitable suppliers from these LCD panel manufacturers?

The world-renowned LCD panel production line is mainly controlled by several enterprises: au optronics in Taiwan;Chi mei electronics in Taiwan, China;Sharp, Japan;South Korea samsung, South Korea LG;Philips;Boe, etc.These companies supply the world"s main demand for liquid crystal displays.

LG Display is currently the world"s first LCD panel manufacturer. It is affiliated to LG group and headquartered in Seoul, South Korea.Its subsidiaries are: LG electronics, LG display, GS caltex, LG chemistry, LG life and health, etc., covering the fields of chemical energy, electronics and appliances, communication and service.LG Display"s customers include Apple, HP, DELL, SONY, Toshiba, PHILIPS, Lenovo, Acer and other world-class consumer electronics manufacturers.LG"s manufacturing base in China is in nanjing, shenyang.

Innolux is a tft-lcd panel manufacturing company founded by foxconn technology group in 2003.The factory is located in longhua foxconn technology park in shenzhen.Innolux has a strong display technology research and development team, coupled with foxconn"s strong manufacturing capacity, to effectively play the vertical integration benefits, to improve the level of the world plane display industry will have a pointer contribution.In March 2010, it merged with chi mei electronics and tong bao optoelectronics.

Au optronics, formerly known as acer technology, was founded in August 1996. It was renamed au optronics after the merger of au optronics and united optronics in 2001.Au optronics is the world"s first tft-lcd design, manufacturing and development company to be publicly listed on the New York stock exchange (NYSE).

Boe, founded in April 1993, is the largest display panel manufacturer in China and a provider of Internet of things technology, products and services.At present, boe has reached the world"s first place in the field of notebook LCD, flat LCD and mobile LCD. With its success in joining the apple supply chain, boe will become the world"s top three LCD panel manufacturers in the near future.

Sharp is known as "the father of LCD panel".Since its founding in 1912, sharp corporation has been developing the world"s first calculator and liquid crystal display, represented by the live pencil, which is the name of the company. At the same time, sharp corporation has been actively expanding new fields, contributing to the improvement of human living standards and social progress.Sharp is already owned by foxconn.

The company has set up tft-lcd key materials and technology national engineering laboratory, national enterprise technology center, post-doctoral mobile workstation, and undertakes national development and reform commission, ministry of science and technology, ministry of industry and information technology and other major national special projects.The company"s strong technology and scientific research capabilities become the cornerstone of the company"s sustainable development.

Back in 2016, to determine if the TV panel lottery makes a significant difference, we bought three different sizes of the Samsung J6300 with panels from different manufacturers: a 50" (version DH02), a 55" (version TH01), and a 60" (version MS01). We then tested them with the same series of tests we use in all of our reviews to see if the differences were notable.

Our Samsung 50" J6300 is a DH02 version, which means the panel is made by AU Optronics. Our 55" has an original TH01 Samsung panel. The panel in our 60" was made by Sharp, and its version is MS01.

Upon testing, we found that each panel has a different contrast ratio. The 50" AUO (DH02) has the best contrast, at 4452:1, followed by the 60" Sharp (MS01) at 4015:1. The Samsung 55" panel had the lowest contrast of the three: 3707:1.

These results aren"t really surprising. All these LCD panels are VA panels, which usually means a contrast between 3000:1 and 5000:1. The Samsung panel was quite low in that range, leaving room for other panels to beat it.

The motion blur results are really interesting. The response time of the 55" TH01 Samsung panel is around double that of the Sharp and AUO panels. This is even consistent across all 12 transitions that we measured.

For our measurements, a difference in response time of 10 ms starts to be noticeable. All three are within this range, so the difference isn"t very noticeable to the naked eye, and the Samsung panel still performs better than most other TVs released around the same time.

We also got different input lag measurements on each panel. This has less to do with software, which is the same across each panel, and more to do with the different response times of the panels (as illustrated in the motion blur section). To measure input lag, we use the Leo Bodnar tool, which flashes a white square on the screen and measures the delay between the signal sent and the light sensor detecting white. Therefore, the tool"s input lag measurement includes the 0% to 100% response time of the pixel transition. If you look at the 0% to 100% transitions that we measured, you will see that the 55" takes about 10 ms longer to transition from black to white.

All three have bad viewing angles, as expected for VA panels. If you watch TV at an angle, most likely none of these TVs will satisfy you. The picture quality degrades at about 20 degrees from the side. The 60" Sharp panel is worse than the other ones though. In the video, you can see the right side degrading sooner than the other panels.

It"s unfortunate that manufacturers sometimes vary the source of their panels and that consumers don"t have a way of knowing which one they"re buying. Overall though, at least in the units we tested, the panel lottery isn"t something to worry about. While there are differences, the differences aren"t big and an original Samsung panel isn"t necessarily better than an outsourced one. It"s also fairly safe to say that the same can be said of other brands. All panels have minute variations, but most should perform within the margin of error for each model.
