lcd panel disassembly made in china

If your phone has image display issues, an unresponsive touch screen or physical cracks or scratches on the glass, this LCD and touch screen assembly is what you need

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.

If your phone has image display issues, an unresponsive touch screen or physical cracks or scratches on the glass, this LCD and touch screen assembly is what you need

China, we’re told, can make anything. If you need some PCBs in a few weeks, there are a few factories in China that will do it. If you need a nuclear reactor, yep, there’s probably a factory in China that’ll do it because nuclear reactors are listed as one of the items facing new tariffs when imported into the United States. No, I am not kidding. What about LCDs? What about old-school character LCDs? Is it possible to find a factory in China that will make you the LCD you want? That’s what [Robert Baruch] will find out, because he’s repairing an old computer with new parts.

The object of this repair and restomod is a TRS-80 Pocket Computer (PC-1), otherwise known as the Sharp PC-1211. It looks like a calculator, but no, it’s a legitimate computer you can program in BASIC. [Robert] bought this computer for a bit more than $5 on eBay ‘for repair’, which means the zinc-air battery was dead, and unfortunately, the LCD was shot. The LCD technically works, but it just doesn’t look good. Sometime in the last thirty years, moisture got in between the layers of glass, polarizing film, and liquid crystal. This is not unique to [Robert]’s unit — a lot of these PC-1s have the same problem, many of these broken seals rendering the computers themselves useless.

This is an ancient computer, and replacements for this LCD are impossible to find, but because the Sharp PC-1211 is well documented, it is possible to find the datasheet for the original display. With that, it’s just a question of finding an LCD manufacturer that will do it. So far, the costs look good — $800 USD ($300 for tooling and 10 samples, $500 for another 200 LCDs) is what it’ll take to get a few units. [Robert] already has a few people interested in repairing their own Pocket Computers. You can follow the eevblog thread here, or check out the video below.

What exactly is short in the market? Your iPhone’s screen is one solid unit made up of several elements that are fused together with OCA (optically clear adhesive). The exterior glass, the digitizer panel (touch sensor), the polarizer and LCD panel. The LCD panel is the key component that is in short supply. Originally Apple had 3 manufacturers to produce LCD panels (LG, Sharp and Toshiba). Apple’s authorized manufacturers have the exclusive technology to produce LCD panels. Other Chinese manufacturers can copy the glass, digitizer, polarizers, OCA, flex cables, backlights, frames and everything except for the main component of the LCD assembly.

How were we getting these parts before? A big leak in Apple’s supply chain. The iPhone 5, 5S and 5C all share most of the same raw components including the LCD panel, the only difference is the flex cable and plastic frame. Independent factories in China can produce these components and can manufacture any 5 series assembly from an LCD panel. Shown on the left is a pulse pressing machine, used to connect the flex cable to the LCD. We use one of these to repair LCDs with damaged flex cables.

So what’s happening?A few things, first Apple has cut off LG and Toshiba, making Sharp their exclusive supplier for iPhone LCD panels and implemented very tight security. Secondly, they have had Foxconn destroy stockpiles of series 5 LCD panels to reduce the parts and material leakage to factories that re-engineer them for the independent repair industry. Along with this strategy, Apple has instructed Foxconn to reduce series 6 materials leakage from their manufacturing centers. Lastly, Apple is working aggressively with US Customs to seize inbound parts.

How long is this shortage going to last? In short,we have no idea. At the time of this writing, LCD prices have been steadily rising for 6 months and replacement iPhone 6S LCDs cost twice what Apple charges for their repair service. Apple does not intend to compete with independent repair shops, instead they are squeezing the profit out of the industry. LCD refurbishing may help shops cut cost but without new LCD panels entering the system it won’t last long.

What does this mean for the independent repair community?Apple is the only repair operation that is immune. Even the Chinese LCD refurbishing plants used by the large chain repair companies are running out of LCDs. Continually rising costs may push out the big chains but with lower overhead and clever problem-solving, the owner-operated shops stand a fighting chance.

Since the iPhone 7/7 Plus has been released for quite a long time, finally the China made iPhone 7/7 Plus screen replacementscame out in the market. we’ve got some iPhone 7 series LCD screen replacements samples and done some tests on them, now let’s take a closer look at these new iPhone 7 series LCD screen replacements!(TianmaandLGsources for testing)

During our test, we found that the display color between our after-market iPhone 7 screen and original screen seems a little different although they are not effecting the touch function. And to be honest, there may have some black dots on the screen because of impurities within the screen module when laminating the LCD and backlight together, without any doubt, this can be solved with technical improvement.

The China-Made iPhone 7 series LCD screen assembly replacement still remains to be improved in quality and performance compared to the original ones, the exposed IC, heavier screen flex cable ribbon, and the screen color difference, the touch function stability, although the price is attractive. However, the China made iPhone 7 series screen replacement is under the improvement, and sooner or later their quality and performance can be quite close to original ones and acceptable, if you"re going to stock up some non-original iPhone 7 series LCD screen replacement, pay more attention and we’ll keep you updated with further information about after-market iPhone 7 series screen replacement!

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.
