line lcd display made in china

China’s new display industry has become the largest in the world, with an annual production capability reaching 200 million square meters, making it a vital force in upgrading information consumption and strengthening the digital economy, according to the Ministry of Industry and Information Technology (MIIT).

In 2021, the output value of China’s display industry reached about 586.8 billion yuan, a figure nearly eight times that of 10 years ago, data from the China Optics and Optoelectronics Manufactures Association LCB, or CODA, showed. The area of the country’s display panel shipments stood at about 160 million square meters, over seven times larger than 10 years ago. The size of China’s display industry and the area of its display panel shipments both ranked first in the world.

China has made breakthroughs in some core technologies in key fields. Chinese liquid crystal display (LCD) enterprises have broken technical barriers and taken 70 percent of the global market share. Chinese companies have also acquired key technologies in organic light emitting diode (OLED) and rapidly expanded their production scale. China is also catching up in new-generation display technologies.

China will make greater efforts to gain a foothold in the medium and high ends of the industrial chain of the new display industry, said an official with the MIIT.

It appears too soon to say that Samsung Display and LG Display, the nation’s top display makers, will exit from the less lucrative LCD market amid a cutthroat competition with Chinese rivals with cheaper pricing.

Until a few years ago, the two firms had hinted at retiring from the old-school LCD business to focus on more advanced technologies such as upgraded LCDs or OLEDs to widen the gap with Chinese runner-ups.

But experts here say there has been a sign of change in the attitudes more recently, pointing out that their full shutdown of LCD operations ultimately would hinge on elevating profitability of their high-end push.

In 2020 alone, Samsung Display posted a deficit of more than 1 trillion won ($841.5 million) in its LCD business. But it has no other option but to continue production to meet the demand from its parent Samsung Electronics, the world’s largest TV maker.

The firm last year sold its LCD production facility in China to its Chinese rival TCL China Star Optoelectronics Technology, a key supplier to Samsung TVs. But the LCD line in Suzhou, China recently cut its panel supply almost in half, with Samsung’s display unit highly likely to be tasked with filling the void.

“(Samsung Electronics) have few choices but to contract with Samsung Display to make up for its LCD TV set capacity,” said Yi Choong-hoon, chief analyst at UBI Research.

This put Samsung Display‘s full exit plan in disarray. After the sell-off of the Chinese facility, the firm is also scaling down its LCD plant in Asan, South Chungcheong Province, to convert part of the facilities to its quantum-dot OLED lines to supply to set makers including Japanese firm Sony.

LG Display’s LCD business -- with production lines in Paju, Gyeonggi Province and Guangzhou, China -- is poised to generate 2.5 trillion won in operating profit for 2021, up fourfold from the previous year, according to Kim Jung-hwan, an analyst at Korea Investment & Securities, on Thursday.

This comes in sharp contrast with OLED TV earnings estimate. According to Kim, LG Display‘s OLED TV operations will post 152 billion won in operating loss, as its fourth-quarter forecast to generate 62 billion won income was dwarfed by 214 billion won losses for the previous three quarters. Since inception, LG’s OLED panel business has been in the red due to heavy spending.

“A bigger penetration of OLED TVs to consumers is a prerequisitie for a conversion of (LG Display’s) existing LCD TV lines to OLED TV lines,” he said.

Analysts also said LG Display has already streamlined its LCD TV lines under a series of restructuring of LCD TV lines, including a conversion to lines for IT devices including mobile phones.

“(LG Display‘s) LCD TV fabs with low profit margin have completed a retreat in the first half of 2021,” said Kim Sun-woo of Meritz Securities. “LG is now capable of maintaining LCD capacity with a decent profit margin.”

This comes against the backdrop of industry projections that LCD TV panel prices continue to fall steadily over the course of the first quarter, and Chinese rivals are forecast to ramp up dominance in LCD market,

According to US-based market intelligence firm Display Supply Chain Consultants, Chinese firms’ LCD market share on a capacity basis are forecast to rise to 71 percent by 2025, from 53 percent in 2020, far outpacing Korea, Japan and Taiwan, as of June 2020.

Another estimate, released earlier this week, showed the price for LCD TV panels regardless of size -- ranging from 32- to 65-inch -- is projected to fall until March, giving up almost entire gains from July 2020 to July 2021 that is partly attributable to announced exits of Korean LCD panel makers.

The quarter-on-quarter price declines in the first quarter of 2022 to range between 10 percent and 23 percent and average 15 percent, with mid-sized panels taking the largest dip.

“Although the declines are slowing down in the first quarter, they are still severe for panel makers,” noted Robert O‘Brien, co-founder and principal analyst at DSCC.

SEOUL, March 31 (Reuters) - South Korean panel maker Samsung Display has decided to end all of its production of liquid crystal display (LCD) panels in South Korea and China by end of this year, a spokesperson said on Tuesday.

Samsung Display, a unit of South Korean tech giant Samsung Electronics Co Ltd, said in October that it suspended one of its two LCD production lines at home amid falling demand for LCD panels and a supply glut.

“We will supply LCD orders to our customers by end of this year without any issues”, the company said in a statement. (Reporting by Heekyong Yang; Editing by Kim Coghill)

The Korean display industry drove Korea’s exports, making Korea a display powerhouse in the world one exporter just 10 years ago. But it has been put into a position to completely lose its power as Korea’s national strategic industry due to a price war initiated by Chinese display makers and a complex global crisis.

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.

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.

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.

They filed a Swiss patent for the idea on Dec. 4, 1970. Though it attracted scant attention at the time, the milestone now stands as the birthdate of the liquid crystal display (LCD) – the technological platform which has transformed consumer electronics and presented a brilliant new way to view the world.

Early LCD developers took a few years to figure out that specialty glass, not plastic, was the best stable substrate for the delicate LCD circuitry and the color backplane component. Once they did, they turned increasingly to Corning to supply them with extraordinarily stable, flat, fusion-formed glass, able to preserve the critical properties of the liquid crystal and withstand high processing temperatures.

And LCDs rapidly transformed from “passive matrix” models, mostly used in pocket calculators and digital watches, to “active matrix” LCDs in which each sub-pixel was controlled with an isolated thin-film transistor. AMLCDs enabled wide viewing angles; brilliant, fast-moving images; and high-resolution images that had never been possible before.

Corning Incorporated was a critical player in this development, and eventually became the world’s leading supplier of LCD glass substrates. And Corning® EAGLE XG® Glass, the world’s first LCD substrate with no arsenic or other heavy metals, went on to exceed sales of 25 billion square feet, making it one of the most successful products in Corning’s history.
