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.

LG Display has initially intended to halt LCD TV panel production in South Korea by the end of the 2020 while continuing production at its factory in Guangzhou, China.
LG Electronics was especially focused on procuring in-plane switching (IPS) LCD TV panels. LG Display specializes in the technology __ IPS allows for wider viewing angle and color range, as is used in premium LCD TVs.
LG Electronics initially expected that it could procure IPS panels from China’s HKC and Sakai SIO (previously Sharp). But COVID-19 delayed HKC’s ramp up of its H4, 8.6th-generation (2,250mm x 2,600mm) line in China. Sakai SIO in the meantime had difficultly procuring lasses for LCD panel production. Also, for HKC and Sakai SIO, Samsung Electronics is a more important customer than LG. These issues prompted LG Electronics to ask LG Display to extend LCD production.
LG Display produces LCD TV panels at its 7th-generation (1,950mm x 2,250mm) P7 line and 8.5th-generation (2,200mm x 2,500mm) P8 line at Paju. While both lines produce TV panels, P7 makes more of them compared to P8 which focuses on IT panels. Both lines are thought to have production capacities of 120,000 to 130,000 sheets per month.
The higher than expected demand for LCD also played a part in LG Display extending LCD production in Korea. In the third quarter, panel prices increased by 30% from the previous quarter. Price continues to go up.
Not only will P7 and P8 lines extend their production, they may have even higher operations rates than before. LG Display planning to react to demand flexibly.
Samsung Display has previously said it plans to end LCD production by 2020, it continuing to produce them. It has previously said it may extend production from Samsung Electronics’ request. Samsung Display specializes in vertical alignment (VA) LCD panels.
While LG Display isn’t the only manufacturer out there making OLED panels, it’s pretty much the only one that counts when it comes to the size and quality of OLED panels required for today’s TV sets. Reports have recently emerged from multiple sources, though, suggesting that another display manufacturer, BoE, is preparing to start making OLED panels big enough for TV use too.
The well connected people at market research company Display Supply Chain Consultants confirmed on the back of the Display Week showing that BoE really does seem intent on making such large panels on a commercial basis. Assuming that their information is correct (it usually is), it doesn’t require much of a mental leap to think that such a move would spell good news for OLED-loving consumers. After all, more panel suppliers means more competition, which usually in turn means cheaper prices and more innovation.
For starters, don’t forget that BoE’s 95-inch OLED prototype really was a very high-end affair. Its combination of a huge screen and native 8K rather than 4K resolution was joined by a native 120Hz refresh rate, coverage of around 99% of the DCI-P3 colour range, and pretty high peak brightness of 800 nits – the sort of specifications that consumers can currently expect to spend tens of thousands of pounds to secure. LG’s latest ‘mere’ 88-inch native 8K OLED model, for instance, the OLED88Z2, costs a cool £25,000 / $25,000 / AU$60,000 at the time of writing. Even if BoE manages to deliver a king-sized OLED panel cheaply enough to enable TV brands to sell huge OLED TVs for much less than that, it’s safe to say they will still hardly be mainstream propositions.
As OLED-info reports, though, the ‘B5 R&D Line’ in China that BoE is apparently eyeing up for production of its TV-sized panels currently has a very low capacity by today’s panel production standards. It’s certainly not capable of producing anything like the quantities of big-screen OLED panels that a number of LG Display lines can. In fact, its apparent production capacity for large OLEDs appears to be so limited that analysts suspect that BoE likely isn’t even contemplating trying to use it to produce screens for the ‘mass market’, focusing instead purely on the high-end niche.
Actually, if some of the ‘chatter’ surrounding the Display Week show is to be believed, BoE might even struggle to move the premium OLED TV dial, at least in the short term, since while the 95-inch RGBW panel BoE showed apparently impressed in some ways, its overall quality supposedly didn’t feel as if it was yet sufficient for a full real-world roll out. Though I should add that I haven’t found anyone sharing specific examples of the sort of issues the BoE panel allegedly suffered with.
It does appear, on the upside, as if the yield rates of usable panels at BoE’s B5 production line are pretty high, at least. The simple reality, though, is that once you delve even a little behind the eye-catching ‘major new manufacturer eyes big-screen OLED production’ headlines, the prospect of a pitched new battle between two makers of TV-sized OLED panels and the hammering of OLED TV prices that might follow doesn’t look set to become a reality any time soon.
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.
The company decided to stop producing low-margin LCD panels for the domestic TV market to overcome deteriorating display industry conditions. Its Chinese LCD plant also decided to convert some of its TV panel lines to IT devices. LG Display plans to focus on organic light emitting diode (OLED) panels in the second half of this year.
LG Display and Samsung Display are struggling to find their ways out of the deterioration of their performance even after withdrawing from production of liquid crystal display (LCD) panels. The high-priced organic light emitting diode (OLED) panel sector regarded as a future growth engine is not growing fast due to the economic downturn. Even in the OLED panel sector, Chinese display makers are within striking distance of Korean display makers, experts say.
On Aug. 30, Display Supply Chain Consultants (DSCC), a market research company, predicted that LCD TV panel prices hit an all-time low in August and that an L-shaped recession will continue in the fourth quarter. According to DSCC, the average price of a 65-inch ultra-high-definition (UHD) panel in August was only US$109, a 62 percent drop from the highest price of US$288 recorded in July in 2021. The average price of a 75-inch UHD panel was only US$218, which was only about half of the highest price of US$410 in July last year. DSCC predicted that the average panel price in the third quarter will fall by 15.7 percent. As Chinese companies’ price war and the effect of stagnation in consumption overlapped, the more LCD panels display makers produce, the more loss they suffer.
As panel prices fell, manufacturers responded by lowering facility utilization rates. DSCC said that the LCD factory utilization rate descended from 87 percent in April to 83 percent in May, 73 percent in June, and 70 percent in July.
Now that the LCD panel business has become no longer lucrative, Korean display makers have shut down their LCD business or shrunk their sizes. In the LCD sector, China has outpaced Korea since 2018. China’s LCD market share reached 50.9 percent in 2021, while that of Korea dropped to 14.4 percent, lower than Taiwan’s 31.6 percent.
Samsung Display already announced its withdrawal from the LCD business in June. Only 10 years have passed since the company was spun off from Samsung Electronics in 2012. LG Display has decided to halt domestic LCD TV panel production until 2023 and reorganize its business structure centering on OLED panels. Its Chinese LCD production line will be gradually converted to produce LCD panels for IT or commercial products. TrendForce predicted that LG Display will stop operating its P7 Plant in the first quarter of next year.
Korean display makers’ waning LCD business led to a situation in which Korea even lost first place in the display industry. Korea with a display market share of 33.2 percent was already overtaken by China with 41.5 percent) in 2021 according to market researcher Omdia and the Korea Display Industry Association. Korea’s market share has never rebounded in for five years since 2017 amid the Korean government’s neglect. Seventeen years have passed since 2004 when Korea overtook Japan to rise to the top of the world in the LCD industry. Korea’s LCD exports amounted to more than US$30 billion in 2014, but fell to US$21.4 billion last year.
A bigger problem is that Korean display makers may lose its leadership in the OLED panel sector although it is still standing at the top spot. While Korea’s OLED market share fell from 98.1 percent in 2016 to 82.8 percent last year, that of China rose from 1.1 percent to 16.6 percent. Considering that the high-end TV market is highly likely to shrink for the time being due to a full-fledged global consumption contraction, some analysts say that the technology gap between Korea and China can be sharply narrowed through this looming TV market slump. According to industry sources, the Chinese government is now focusing on giving subsidies to the development of OLED panel technology rather LCD technology. On the other hand, in Korea, displays were also wiped out from national strategic technology industry items under the Restriction of Special Taxation Act which can receive tax benefits for R&D activities on displays.
