how to fix an lcd display made in china

Mandy, ETS is obviously a company that you are connected to and this could easily be taken for spam. I think we can make an exception at this time since you are asking a good market research question that may be useful to many.

Having checked out your video, I personally will not use the aftermarket screen as a replacement for my X. It just doesn"t have what I expect for a $1000 USD phone. I recognize that $300 USD for a replacement is hefty but the aftermarket screen does not appear to have the quality that I would expect for my phone.

Broken screen replacement service is provided from thousands of repairs stores and phone parts wholesalers worldwide, iPhone of which are mostly engaged in. So how to purchase reliable LCD screens among so many quality grades from China suppliers? Let me firstly elaborate on the quality grades of the iPhone LCD digitizer assembly that most repair stores and traders used to replace the broken ones.

According to the investigation, 90% of the Chinese iPhone LCD screen suppliers are found selling third-party manufactured screens and seldom sell genuine original LCD screens. Therefore, if your phone screen is broken, there would be a high chance for your screen to be replaced with a non-original one. Why? Maybe the cost and quality are relatively competitive, so why not?

As known, Foxconn is authorized to assemble iPhone, so there are some original iPhone LCD screens leaked from the assemble factory. And there are brought out from the factory for replacement. However the price is definitely high and still, some people care more about the quality of the screen than how much they cost, so for this group of customers, the Original Quality of LCD digitizer assemblies are preferred.

For some LCD digitizers, the LCDs are still working while the front glasses are broken, which can be recycled. Some factories recycled these broken screens by removing the broken front glass and attach a new one, then the LCD digitizer assembly would be new again, which is what called refurbished. Brand new original LCD screens are limited, and the refurbished ones can replenish the shortage of the new original LCD digitizer assemblies, for their quality would be more stable than the third-party manufactured.

Some Chinese factories purchase the original single LCD display, not compete LCD screen from the original factory, and then attach high copy front glass, backlight, etc, materials into a complete LCD screen, which quality is not stable and the display color is slightly different from the ones with high copy backlight. Well, their price would be cheaper and loved by many repair shops and wholesalers.

Under the shortage of original LCD screens, many Chinese factories begin to produce the high copy LCD screen. The stock and supply are getting less and less since about 2015, which leads the price goes higher and higher. Therefore the Chinese manufacturer starts to produce LCD screens with high copy raw materials. With competitive prices and good quality that meet most iPhone users’ needs, they are also popular among many wholesalers and repair shops.

With the premium quality of LCD and OLED screens tested strictly, we’ve helped many clients enlarge their markets worldwide. If you wholesale the LCD digitizer assembly or retail them in your repair shop, more information and sample are supported for your reference, please do not hesitate to contact us or leave your comment to discuss more.

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.

Samsung’s investment in OLED TVs has also been reported by The Elec. The company is no stranger to OLED technology for handhelds, but it exited the large OLED panel market half a decade ago, allowing rival LG Display to dominate ever since.

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.

Samsung has also been showing off its MicroLED display technology at recent trade shows, which uses self-emissive LED diodes to produce its pixels. However, in 2019 Samsung predicted that the technology was two or three years away from being viable for use in a consumer product.

Dell 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.

NOTE: When SupportAssist does not show up in the search results, go to the SupportAssist for PCs and tablets page for information about downloading and installing SupportAssist.

To learn how to manually download and install a device driver such as Chipset, Video card (GPU), and Monitor driver (if required, most monitor drivers are delivered automatically through Windows Update) on your Dell computer, see the Dell knowledge base article How to Download and Install Dell Drivers.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

If you notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Windows Safe Mode does not load any drivers, startup applications, third-party services. This will help us identify if the issue is related to the operating system, video settings, device drivers, or third-party software. To learn how to boot your computer into Safe Mode, see the Dell knowledge base article below based on the operating system that is installed on the computer:

Windows updates can support your Windows operating system in many ways. Windows updates can solve specific problems, provide security patches and protection from malicious attacks, or even add new features to the operating system.

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

NOTE: Depending on the model of the Dell laptop, the shortcut keys to adjust or change the brightness may differ. See the User Guide or User Manual of your Dell laptop for model-specific information.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

Stress Test can thoroughly diagnose the video card (GPU) on your computer and report any potential hardware problem. Running a stress test on your computer can verify if the hardware components are stable and thus reliable.

System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore must be used before you try to restore the operating system to factory default settings.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.

WARNING: Restoring or resetting the computer to factory default settings will erase all personal data on the computer. Back up all important data like documents, images, music files, spreadsheets, videos to an external hard drive or a cloud-based backup like Microsoft OneDrive.

Dell computers are built with a small amount of hard disk space that is reserved for reinstalling the operating system. This method is the easiest way to restore the computer to factory condition. The restoration process deletes all user data from the computer, so be sure to back up all your files before starting this process.

As is known to all, in the past 40 years, China has made remarkable achievements in its industry. With the establishment and improvement of a modern industrial system with complete categories, China has long been the world’s largest manufacturing country.

This is mainly because China has a large population, about the same as the rest of the developed world put together, but it has not yet developed to the point where services account for a large proportion. Because China has a large population and a large number of employed people, labor is cheaper than in other countries. Foreign enterprises can take advantage of China’s labor force by putting their products into production in China, which not only increases the employment rate of Chinese people but also saves a lot of costs in the production of products. Therefore, made in China is so popular.

A guy on Quora mentions that”If you import a lot of raw Material from broad, it will cost a lot of money, but China has a very special weapon: infrastructure. Since the demand for products (mostly commodities) drives demand for raw material, that drives demand for infrastructure to route these raw materials effectively and cheaply. Unlike India, China has that infrastructure and system, and so raw material can flow in large batches and routed effectively to minimize cost.”

It is also true that in the eyes of foreign companies, Chinese products in almost any field can be produced. China’s development in the production field in recent years is very comprehensive, including raw materials, production, logistics, trade, and other supporting industrial chains, which can be said to be very complete. Therefore, foreign enterprises can find a complete industrial chain in a very short time when they come to China, so the reputation of Chinese manufacturing is also very good.

When it comes to cheap Labour, it is much cheaper in south-east Asia than in China. But why is China so popular? This involves the quality of the product. The reason why the labor force in many countries in southeast Asia is cheap is mainly that the economic level of these countries is not high, so no matter the production technology or technological level is inferior to China. To ensure the quality of their products, foreign companies naturally prefer to choose China.

In terms of product production efficiency, China is hard to compare with many other countries. According to relevant data, domestic product manufacturing efficiency is the highest in the world. On the one hand, this is because China’s factories have more comprehensive equipment and a high level of science and technology, which can shorten the production cycle of products. On the other hand, it is because of the high quality of Chinese workers, strong learning ability, and developed transportation, which also speeds up the operation of all aspects of product production.

In order to export more products to other parts of the world, the Chinese government has only a VAT system and only taxes value-added services. As a result, production costs are much cheaper than in other countries. On the other hand, the United States and some other developed countries do not impose low import tariffs on Chinese goods.

It is believed that with the continuous development of Chinese manufacturing and science and technology, made-in-china manufactures will become more popular in the future.

It is the first time that China took over the No. 1 spot in the display market, which Korea has always been a leader in. The title of “the strongest country in display market” is lost after 17 years. It would not be possible to reclaim the No. 1 spot if Korea cannot find a way to expand investment in next-generation displays such as organic light emitting diodes (OLED).

According to market research firm Omdia, China recorded $64.8 billion in sales including LCD and OLED in the global display market last year. China took over Korea’s No. 1 spot with a market share of 41.5%. Korea"s market share fell 8.3 points (p) to 33.2%. This is the first time since 2004, in 17 years, that Korea had to hand over the No. 1 spot. Korea had a 9.4 p advantage in market share over China up until 2019.

China overtook Korea and seized power in the LCD market by offering a low-priced products. BOE, China"s largest panel manufacturer, has become the world"s largest LCD manufacturer with help of the subsidy from the Chinese government. LCD sales was $28.6 billion last year, accounting for 26.3% of the total LCD market. The sales of Chinese companies such as BOE, CSOT, Tianma, and Visionox increased significantly as demand for TV and information technology (IT) devices increased with the prolonged COVID 19 and increased price of LCD panel.

After taken over in the LCD market, Korea is focusing on the highly-valued OLED market. Samsung Display and LG Display are transforming their LCD production lines to OLED. Korea is the No. 1 with 82.3% of the global OLED market shares according to Omdia, and China’s market share only accounts for16.6%.

China"s dominance is expected to continue for some time because the large display market such as TVs and laptops still depends on LCD. Only when Korea starts to reduce OLED panel prices by mass producing OLED, then Korea can replace the LCD market led by China.

Samsung Display and LG Display were not able to make a decision on investment plans for large OLED plants due to problems with yield and investment funds. Samsung and LG are expected to invest more than KRW 7 trillion in OLED facilities this year according to the industry. Mass production from these companies is expected to begin in the second half of next year even when new and expanding existing investments are made this year.

China has also started to narrow the gap with Korea in OLED industry. BOE and other companies have commercialized OLED for small and medium-sized displays such as mobile, laptop, and tablet. Following LCD market, China is threatening Korea in OLED market as well as China expands OLED market share mainly in the Chinese smartphone market.

Critics are pointing out that Korea needs to expand in OLED market and develop new technologies in order to maintain the OLED gap with China. Korea must take control over the large TV panel market, which has a large technological gap with China, and create a new form factor with new technologies such as flexible, rollable, and bendable panels.

Some criticizes that R&D support and interest are required even if Korean government does not provide subsidies like the Chinese. It is daunting that the government seems to have lost interest in the display industry by giving support for the government’s national talent developing project, and cutting the support for the next-generation display field.

An official from the display industry said, “With the government-led industrial promotion policy and copious domestic market, China is making an effort to solidify its leading position in the display industry. There is a neglect on display industry in Korea since the display promotion policy is almost non-existent compared to semiconductors and batteries.”

WITH COVID‐19 INFECTIONS REPORTED IN MORE THAN 100 countries by early March 2020, the health crisis" impact on the display manufacturing industry was being felt well beyond Wuhan, China, where the first cases of the illness were reported.

Faced with a reduced workforce caused by travel bans and quarantine conditions, LCD and OLED fabrication plants (fabs) across China struggled to resume normal operations in early‐ to mid‐February. Chinese LCD fabs were only expected to have a capacity utilization of 70 to 75 percent for the month compared to a normal rate of 90 to 95 percent, according to research from Omdia Display.

That labor challenge was exacerbated further in mid‐to‐late February by bottlenecks in chemical materials and key components such as polarizers and printed circuit boards. “Those materials and component companies are facing the same situation—a shortage of labor, a shortage of logistics support, and the quarantine procedures,” says Omdia Display"s Senior Director David Hsieh. The net result could be as much as a 40 to 50 percent drop in overall display production in China for February, he notes.

The biggest impact is in LCD displays for TVs and notebook computers. By late 2019, the prolonged issue of LCD panel over‐supply driven by Chinese fabs had begun to reverse course as Korean manufacturers restructured their capacity, shutting down some fabs and converting others to OLED production. According to Hsieh, concerns about an LCD panel supply going forward already had spurred some TV manufacturers to increase orders, and now that LCD production in China is slowing as a result of the COVID‐19 outbreak, LCD panel makers are seeking sharp price increases from their original equipment manufacturer (OEM) customers, with a month‐to‐month jump of as much as 10 percent in some cases.

Omdia had originally forecast that the price for an open‐cell LCD TV panel was going to rise by $1 or $2 per month in February, but the actual increase may wind up being $3 to $5 for the month. “The problem is the coronavirus is coming so fast [that] the panel maker has been given a very good reason to increase the price radically,” Hsieh says. He also expects prices to increase for notebook displays, for which he predicts a 30–40 percent decrease in production for 2020"s first financial quarter (Q1), because of shortages in LCD modules.

While concerns over COVID‐19 caused the cancellation of the Mobile World Congress (MWC) tradeshow in Barcelona, Spain, the near‐term impact of the epidemic on smartphone display production appears to be minimal. Q1 production of smartphone displays is generally slow, notes Hsieh, with OEMs traditionally announcing new smartphone models at MWC, but not placing orders for displays until Q2 or Q3. And the bulk of OLED displays, which dominate the market for new high‐end phones, also are made by Korean manufacturers such as Samsung Display. Last year, Korean fabs shipped 433 million smartphone displays, while China was at 54 million. Hsieh said initial targets for 2020 were 476 million smartphone OLEDs shipped from Korea and 128 million from China, which would more than double China"s total from last year. Although the coronavirus will cause a “short‐term setback” for Chinese smartphone OLED makers, he still has a target of more than 100 million Chinese OLEDs.

In Wuhan itself, there are five major fabs, with four making smartphone displays. China Star and Tianma each operate a low‐temperature polycrystalline silicon LCD fab and a flexible OLED fab in the city, while BOE has a new Gen 10.5 LCD plant aimed at TV panels. Hsieh says that the China Star and Tianma OLED fabs are both in the ramping‐up stages, and the new BOE fab also is moving slowly. The biggest impact of COVID‐19 in Wuhan may be on the China Star Gen 6 OLED plant. Along with BOE, it"s slated to be a key supplier of flexible OLED panels for Lenovo"s new Motorola Razr foldable phone. “It"s unfortunate timing,” Hsieh says. —Glen Dickson
