China"s first 8.5-generation TFT-LCD production line was launched in Bengbu, East China"s Anhui province, on June 18, 2019, representing a breakthrough in the production of high-definition LCD screen, Science and Technology Daily reported.

TFT-LCD, or Thin Film Transistor Liquid Crystal Display, is key strategic material of the electronic information display industry. The Gen 8.5 TFT-LCD production line, launched by the Bengbu Glass Industry Design and Research Institute of the China National Building Material Group, will produce high-definition LCD screens of 55 inches, the report said.

According to the Liquid Crystal Branch of the China Optics and Optoelectronics Manufactures Association, the demand for TFT-LCD in the Chinese mainland was about 260 million square meters in 2018, including 233 million square meters" Gen 8.5 TFT-LCD. However, the annual supply of domestically made TFT-LCD is less than 40 million square meters, with all of them Gen 6 or below, which cannot meet the demand in scale and quantity.

The association predicted that China"s market demand for Gen 8.5 TFT-LCD or above will exceed 300 million square meters by 2020, accounting for 49.6 percent of the total global demand.

The production and control precision of Gen 8.5 TFT-LCD is comparable to that of the semiconductor industry, representing a higher level of large-scale manufacturing of modern glass industry.

The institute in Bengbu, with 60 years of expertise in glass, has finally made a breakthrough in the production of Gen 8.5 TFT-LCD, and will provide key raw material guarantee for China"s LCD panel industry after it goes into mass production in September, the report said.

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.

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.

SEOUL (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 the end of this year, a spokeswoman 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.

In October, the Apple Inc supplier said it will invest 13.1 trillion won ($10.72 billion) in facilities and research to upgrade a production line, as it contends with oversupply amid weak global demand for smartphones and TVs.

The investment for the next five years will be focused on converting one of its South Korean LCD lines into a facility to mass produce more advanced “quantum dot” screens.

Samsung Display’s cross-town rival LG Display Co Ltd said earlier this year that it will halt domestic production of LCD TV panels by the end of 2020.

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.

“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.

► When the leading Korean players Samsung Display and LG Display exit LCD production, BOE will be the most significant player in the LCD market. Though OLED can replace the LCD, it will take years for it to be fully replaced.

When mainstream consumer electronics brands choose their device panels, the top three choices are Samsung Display, LG Display (LGD) and BOE (000725:SZ) – the first two from Korea and the third from China. From liquid-crystal displays (LCD) to active-matrix organic light-emitting diode (AMOLED), display panel technology has been upgrading with bigger screen products.

From the early 1990s, LCDs appeared and replaced cathode-ray tube (CRT) screens, which enabled lighter and thinner display devices. Japanese electronics companies like JDI pioneered the panel technology upgrade while Samsung Display and LGD were nobodies in the field. Every technology upgrade or revolution is a chance for new players to disrupt the old paradigm.

The landscape was changed in 2001 when Korean players firstly made a breakthrough in the Gen 5 panel technology – the later the generation, the bigger the panel size. A large panel size allows display manufacturers to cut more display screens from one panel and create bigger-screen products. "The bigger the better" is a motto for panel makers as the cost can be controlled better and they can offer bigger-size products to satisfy the burgeoning middle-class" needs.

LCD panel makers have been striving to realize bigger-size products in the past four decades. The technology breakthrough of Gen 5 in 2002 made big-screen LCD TV available and it sent Samsung Display and LGD to the front row, squeezing the market share of Japanese panel makers.

The throne chair of LCD passed from Japanese companies to Korean enterprises – and now Chinese players are clinching it, replacing the Koreans. After twenty years of development, Chinese panel makers have mastered LCD panel technology and actively engage in large panel R&D projects. Mass production created a supply surplus that led to drops in LCD price. In May 2020, Samsung Display announced that it would shut down all LCD fabs in China and Korea but concentrate on quantum dot LCD (Samsung calls it QLED) production; LGD stated that it would close LCD TV panel fabs in Korea and focus on organic LED (OLED). Their retreats left BOE and China Stars to digest the LCD market share.

Consumer preference has been changing during the Korean fab"s recession: Bigger-or-not is fine but better image quality ranks first. While LCD needs the backlight to show colors and substrates for the liquid crystal layer, OLED enables lighter and flexible screens (curvy or foldable), higher resolution and improved color display. It itself can emit lights – no backlight or liquid layer is needed. With the above advantages, OLED has been replacing the less-profitable LCD screens.

Samsung Display has been the major screen supplier for high-end consumer electronics, like its own flagship cell phone products and Apple"s iPhone series. LGD dominated the large OLED TV market as it is the one that handles large-size OLED mass production. To further understand Korean panel makers" monopolizing position, it is worth mentioning fine metal mask (FMM), a critical part of the OLED RGB evaporation process – a process in OLED mass production that significantly affects the yield rate.

Presently, Chinese panel fabs are investing heavily in OLED production while betting on QLED. BOE has four Gen 6 OLED product lines, four Gen 8.5 and one Gen 10.5 LCD lines; China Star, controlled by the major appliance titan TCL, has invested two Gen 6 OLED fabs and four large-size LCD product lines.

Remembering the last "regime change" that occurred in 2005 when Korean fabs overtook Japanese" place in the LCD market, the new phase of panel technology changed the outlook of the industry. Now, OLED or QLED could mark the perfect time for us to expect landscape change.

After Samsung Display and LGD ceding from LCD TV productions, the vacant market share will be digested by BOE, China Star and other LCD makers. Indeed, OLED and QLED have the potential to take over the LCD market in the future, but the process may take more than a decade. Korean companies took ten years from panel fab"s research on OLED to mass production of small- and medium-size OLED electronics. Yet, LCD screen cell phones are still available in the market.

LCD will not disappear until OLED/QLED"s cost control can compete with it. The low- to middle-end panel market still prefers cheap LCD devices and consumers are satisfied with LCD products – thicker but cheaper. BOE has been the largest TV panel maker since 2019. As estimated by Informa, BOE and China Star will hold a duopoly on the flat panel display market.

BOE"s performance seems to have ridden on a roller coaster ride in the past several years. Large-size panel mass production like Gen 8.5 and Gen 10.5 fabs helped BOE recognize the first place in production volume. On the other side, expanded large-size panel factories and expenses of OLED product lines are costly: BOE planned to spend CNY 176.24 billion (USD 25.92 billion) – more than Tibet"s 2019 GDP CNY 169.78 billion – on Chengdu and Mianyang"s Gen 6 AMOLED lines and Hefei and Wuhan"s Gen 10.5 LCD lines.

Except for making large-size TVs, bigger panels can cut out more display screens for smaller devices like laptops and cell phones, which are more profitable than TV products. On its first-half earnings concall, BOE said that it is shifting its production focus to cell phone and laptop products as they are more profitable than TV products. TV, IT and cell phone products counted for 30%, 44% and 33% of its productions respectively and the recent rising TV price may lead to an increased portion of TV products in the short term.

Except for outdoor large screens, TV is another driver that pushes panel makers to research on how to make bigger and bigger screens. A research done by CHEARI showed that Chinese TV sales dropped by 10.6% to CNY 128.2 billion from 2018 to 2019. Large-size TV sales increased as a total but the unit price decreased; high-end products like laser TV and OLED TV saw a strong growth of 131.2% and 34.1%, respectively.

The demand for different products may vary as lifestyles change and panel fabs need to make on-time judgments and respond to the change. For instance, the coming Olympics is a new driving factor to boost TV sales; "smart city" projects around the world will need more screens for data visualization; people will own more screens and better screens when life quality improves. Flexible screens, cost-efficient production process, accessible materials, changing market and all these problems are indeed the next opportunity for the industry.

Samsung Display has been working on managing its customers since it announced its plan to withdraw from its LCD business. Vice-President Choi Joo-seon of Samsung Display who leads the large panel business sent letters to Chinese customers and explained to them about Samsung Display’s plan to withdraw from its LCD business and presented them with new ways of collaboration.

According to the industry, it is heard that Vice-President Choi Joo-seon of Samsung Display who oversees Samsung Display’s large panel business and QD (Quantum Dot) business sent letters to Samsung Display’s key customers from China and informed them about Samsung Display’s plan to stop supplying LCD panels.

“We explained to our Chinese customers about a very important decision we made based on business strategy.” said Vice-President Choi. “We have made major losses from our LCD business as the global large LCD panel market has gone through a recession for the past few years.”

“In order to overcome this crisis and to secure competitive edge within the global large panel market, we started investing in QD display since October of last year.” said Vice-President Choi. “We are going to stop producing large LCD panels after this December and accelerate our QD display business instead.”

Samsung Display recently announced that it would stop producing LCD panels and shift its production towards QD display. As Its profitability and business value in LCD has fallen off as LCD prices have continued to drop due to excess supplies from Chinese companies. This decision was made in just 15 days after Vice-Chairman Lee Jae-yong of Samsung Electronics visited the Asan complex on March 19th and examined business strategies.

It seems that Vice-President Choi sent letters to Chinese customers in order to prevent any disruption to their operations and to look for new ways of collaboration by informing them about Samsung Display’s plan to shift its production towards QD display. Chinese TV makers such as Hisense, Haier, TCL, Changhong, and Konka currently use Samsung Display’s LCD panels. Samsung Display can secure continuity and a steppingstone for growth when these companies start producing their products using QD display.

“Because we believe that out decision to withdraw from LCD business will have an impact on your business, we are going to discuss about possible amounts of quarter supplies and timing for discontinuation.” said Vice-President Choi through his letters. “We hope to continue to have collaborations even after we stop producing LCD panels in order to achieve new innovation.”

Samsung Display is going to focus on the “Q1 line” that is a QD display production line. The Q1 line will replace Samsung Display’s current Gen 8 LCD production line. Considering the fact that the Q1 line is expected go on operation next year, it is likely that Samsung Display will clean out the Gen 8 LCD line by end of this year. Samsung Display sent major equipment and systems from the 8-1 line to a Chinese LCD module maker called Efonlong. It is expected that Samsung Display will actively push for selling low-generation LCD production lines located in Suzhou and others.

We have a lot of different supplyers. The latest batch of iphone 4s LCD"s all have this problem. Iphone5/5s/6(+)/6s(+) are all fine. We are now testing all the LCD"s out of the batch. All have the dark lines. It looks fine at first. But when you get a pop-up or get the shutdown screen, that is when you see the dark lines.

We repair in an ESD space, having ESD wristbands and heelbands. We are testing the lcd"s using a disassembled iphone. So this issue (we have here) has nothing to do with the metal plate.

One of the people here said something about static getting in the screen when they get referbrished. But is there any way to get this charge out? Someone told us to put the connectors on the table so it could discharge. But this does exactly nothing. Does anyone have a solution?

And what i found is; White lines mean it"s not properly connected or the flex is damaged. This is a different problem then the dark lines i was talking about. Stripes (more then 3) are also a result of a bad connection.

According to industry insiders, Samsung has taken the decision to close down its last LCD production lines, coming into effect six months sooner than expected. According to industry insiders talking to the Korea Times, the June closure has been hastened due to the precipitous fall of LCD pricing driven by competitors based in China and Taiwan. As the news comes via unnamed "industry insiders", take the news with a healthy amount of salt until an official statement is made.

The apparent sudden change of heart by Samsung needs little supplementary explanation if you cast your eyes over the chart above. The chart, courtesy of Display Supply Chain Consultants (DSCC), shows the TV panel price index plotted against year on year change from January 2015 to today. The steepness of the decline seen from late 2021 is enough to give an analyst vertigo. It may show some signs of bottoming out now, but please note that we are in negative territory, approaching -60% pricing YoY.

Samsung Display is an important player in the business of making flat panel displays. The South Korea-based firm makes some of the best screens for devices spanning tiny wearables to full wall-sized modular TVs. Some of its displays go into PC monitors that are own branded, and others will be used by partners like Asus and Alienware.

It is expected that employees who were part of the LCD business operations will be reallocated to Samsung Display"s quantum dot (QD) and organic light-emitting diode (OLED) screen production. Hopefully the removal of the LCD lines, and rebalancing into QD and OLED, will bring economies of scale to Samsung"s operations and help make these vibrant modern screen technologies more accessible.
