lcd display issues made in china

Chinese display producers, which have massively rolled out low-priced products to dominate the global liquid crystal display (LCD) panel market, are struggling as LCD panel prices have plunged. They cannot even survive without the Chinese government’s subsidies.

Chinese display companies, such as BOE, Caihong Group, GoVisionox (GVO), CEC Panda, posted poor results in the first half of this year due to lower LCD prices, according to market research firm IHS Markit on Oct. 9. LCD TV panel prices had continued to fall until last month since the third quarter of 2017.

LG Display was hit hard by the drop in LCD prices, but the Chinese firms which have driven South Korean competitors out of the market with low-priced products, are also facing a tough situation now.

BOE, the largest LCD panel producer in China, posted US$68 million (81.59 billion won) in operating profit in the second quarter but US$60 million (71.99 billion won) of it was subsidies from the Chinese government. Considering the fact that BOE"s sales came to US$4.19 billion (5.03 trillion won) in the second quarter, the firm’s actual operating profit to sales ratio, excluding subsidies, is only 0.2 percent. IHS Markit said, “A considerable portion of the Chinese government’s subsidies is regarded as a non-operating income. If subsidies are all excluded, Chinese companies may actually run into red figures.”

The situation is very much the same with Caihong Group, the parent company of CHOT. The group recorded an operating profit of US$13 million (15.61 billion won) in the second quarter thanks to the government’s subsidies worth US$69 million (82.86 billion won). Excluding the subsidies, it showed a loss. GVO had an operating profit of US$105 million (126.11 billion won) in the second quarter but more than US$104 million (124.90 billion won) of them came from the government. It cannot even stay in business without the government’s subsidies. Tianma has been receiving the smallest amount of the government’s subsidies among Chinese display panel producers but 32.7 percent, or US$19 million (22.81 billion won), of its operating profit of US$58 million (69.65 billion won) in the second quarter came from the government.

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.

Samsung Display is ending direct production of LCD panels in South Korea and China by the end of this year, according to a report by the global news agency Reuters.

The report suggests the electronics giant will instead focus production efforts on displays that use quantum dots technology – which in simple terms is the basis for a filter on displays that increases brightness and color volume.

Samsung’s gorgeous QLED displays (got one) are LCDs with a quantum dots layer, and there is lots of R&D work going on to add quantum dots to OLED displays, which would boost their brightness and color volume as well.

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.

This is happening, maybe not entirely but heavily, because Chinese government-backed manufacturers like BOE have greatly upped production capacity for LCD TVs, driving prices  and margins down for consumer and professional display products.

Samsung is also putting more focus on direct view LED – with well-respected indoor and outdoor products, and forays into premium displays like The Wall series.

Samsung Display reportedly plans to shut down ahead of schedule four of its LCD panel production lines as early as in the third quarter of 2020, as the vendor is looking to accelerate its exit from the LCD segment, according to industry sources.

The ongoing coronavirus pandemic is apparently an impetus pushing Samsung Display to phase out its LCD panel production, as the crisis has wrecked havoc on the global economy, slowing down business activities and halting sports events such as the Tokyo Olympics 2020, which is seriously undercutting demand for TVs and adding downward pressure on panel prices, said the sources.

Samsung Display also plans to keep production at its 8.5G LCD fab in Suzhou, China in the meantime, while overhauling its L7-2 fab for production of POLED panels and its L8 fab for QD-OLED panels, indicated the sources.

The Korean panel maker is also looking to halt the operations of the Suzhou 8.5G line by the third quarter of 2022 and is currently in talks to sell the LCD panel plant to Chinese panel makers, said the sources, adding that the completion of a deal will mark Samsung Display ‘s exit from the LCD TV panel market.

Presumably, while Samsung may not be directly manufacturing LCD, the industry will still be able to buy Samsung LCD displays – just manufactured, as some will be already, by other companies in China and Taiwan.

I only observe and have no direct involvement in how the display giants operate, but from my perch in the bleachers, it seems to make sense to get out of producing a commodity product,  when you are up against Chinese manufacturers who can make and sell them for less because of government subsidies and lower labor costs.

I really don’t see direct view LED taking the place of single LCD displays, but much of the future of signage is in LED that fills entire walls and other surfaces, inside and outside.

Most of their commercial displays are manufactured in Mexico. I am assuming this is referring only to their consumer displays as nothing is even mentioned about their Mexico facilities here.

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.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

Since most display manufacturing has to be done in a cleanroom and handling the glass requires such precision, the factory is heavily automated.As you watch the glass come in, it is placed into giant cassettes by robot handlers, and the cassettes are moved around throughout the factory.At each step, robots lift a piece of glass out of the cassette, and position it for the processing machines.Some of the machines, like the ones that deposit silicon or ITO, orient the glass vertically, and put them inside an enormous vacuum chamber where all the air is first pumped out before they can go to work.And then they somehow manage to deposit micrometer thin layers that are extremely uniform.It is a miracle that any of this stuff actually works.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.

Some chemicals in liquid crystal displays (LCDs) could alter genes, they said. Animal cells mutated unexpectedly if exposed, and preliminary results of their ongoing study published in Proceedings of the National Academy of Sciences on Monday showed that one of the most polluted places was the home.

Over the years, screen panel manufacturers have pushed LCD technology to higher resolutions and faster refreshing rates, but the chemical composition of the liquid crystal that fills their screens has hardly changed.

Samsung Display will stop producing liquid crystal display (LCD) panels in China and South Korea at the end of the year in order to concentrate on the new generation of "quantum dot" (QD) screens, Reutersreports. Any LCD orders made before the end of the year will still be fulfilled.

Samsung made its plans for QD tech known last year, when it announced its $11 billion investment into a plant capable of manufacturing true QLED TV screens that self-illuminate. Traditionally, Samsung"s quantum dot LCD tech puts LED backlights behind a filter (so the display doesn"t match up to the likes of say, LG"s OLED TVs), but research at the end of 2019 helped mitigate some development problems, such as burn-in. Samsung"s forthcoming QD tech instead relies on indium phosphide instead of toxic cadmium, and has a lifetime of up to a million hours.

The multi-billion dollar investment will take place over five years and will see Samsung convert one of its existing South Korean LCD lines into a facility to mass produce these screens. Falling demand for LCD products and a manufacturing supply glut means Samsung is obviously looking for new avenues, so for the company to essentially do away with a tried-and-tested technology and go all-in on another suggests that QD screens are very likely to feature in our viewing futures.

Dell Technologies recommends ensuring that the device drivers and BIOS are up to date using the SupportAssist application for optimal video performance and to help resolve common video-related issues.

It is essential to verify if the problem is inherent with the monitor, video card (GPU) or video settings on your computer. A straightforward way to identify this is to connect the computer to a known-good external monitor or TV and ensure that the display cable (S-video, VGA, DVI, HDMI, DisplayPort, USB-C, or Thunderbolt 3) is firmly connected to the video port on the computer and the monitor.

If the issue persists on the other monitor it may be due to the video card (GPU) or video settings and not the monitor, go to the step Verify display or video issue in Windows Safe Mode. Else go to the next step.

Performance issues may occur if there is any type of damage that is caused to the display cables or the LCD screen. LCD screen may show that symptoms like LCD screen stops working, work intermittently, color mismatch, flickering, display horizontal or vertical lines if there is damage to the display cables or the LCD screen.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, it is a good practice to isolate the monitor by running a diagnostic test on the Dell monitor.

NOTE: Self-test feature check (SFTC) helps check if the Dell monitor is working normally as a stand-alone device. To check for screen abnormalities such as flickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade, and so on, run the integrated self-test (BIST) or integrated diagnostic (BID) test.

Dell monitors can be reset to factory default settings using the on-screen display (OSD) menu. This can be accessed using the buttons or joystick that is available on the Dell monitor. For step-by-step instructions to reset a Dell monitor to factory default settings, see the User Guide of your Dell monitor at the Dell Manuals website.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of your Dell monitor. Changing the display settings can help resolve several types of video issues.

The rumor that the China made iPhone LCDs can’t survive the upcoming iOS updates existed for quite a long time which aroused panic among repair shops. Many repair shops who want to use/have already used these screens to compete with authorized repair are wondering, will Apple brick these iPhone to kill the third party repair? We ETrade Supply don’t think so and here is why:

Do you still remember that users sued Apple for bricked iPhone due to "error 53"? The situation is almost the same except only few people have let their home button be replaced by third party repair shops. How many China made iPhone LCDs have been sold? We don’t have the exact number. However, from what we know, the number should be over 1 million pieces at least. Will Apple brick millions of iPhones just to kill third party repairs?

Same rumors for the 4/4S screen before. The OEM LCDs for 4/4s died out for quite a long time, all screens supplied were China copy one since 2 years ago. Not a case of bricked phone/unusable have showed for the updating to the new iOS system.

The most possible reason that this rumor has been created—is just to cut the price of the China copy iPhone LCD and more possibly-- the demand for it.

A week before the Apple event in March 2016, the rumor was “China made iPhone LCDs can’t survive in the coming iOS 9.3 updates”, the price of these LCDs dropped significantly and everyone was holding their orders, waiting to see the result. Within one week, the price has dropped around $10/pc. After people found out that they did survive, the price increased again and here came the rumor “the China made iPhone LCDs won’t survive the iOS 10 updates”.

Since last June, more and more repair shops have accepted the China made iPhone LCDs because less OEM screens are supplied. A large certain amount of demand of OEM iPhone screens has been moved the China made ones. The rumor that “the China made iPhone LCDs won’t survive the newest iOS updates” will sure bring some demand back to those crappy OEM screen which have been used for quite a long time/ refurbished for multiple times.

The rumor is “ALL the China made iPhone LCDs won’t survive the iOS 10 updates”, not only for 5 series. As we all know, there are already China Made 6 screens in the market. Those who stocked large amount OEM 6 screens will be happy to see people still paying high price for the OEM 6 screens for quite a long time.

The supply chain of cell phone replacement parts is sophisticated, unclear and without any standards, which make it look more like gambling. Find a reliable long-term relationship partner who can grow with you is the key to success for repair shops. If you have any questions regarding the China made LCDs, please leave your comment below!
