What will it bring to repair industry when iPhone 7S features OLED screen?

According to the news from The Korean Herald, Samsung has signed a contract with Apple about supplying 100 million OLED glass lens in 2017. Another news revealing that LG has also added a product line for OLED screen, which will be put into production in early 2017. So in early 2017 or at the latest by 2018, we will see iPhone made of OLED screen.
As for the influences to the mobile phone repair industry, let’s first take a look at the supply of the mobile phone repair parts market.

Take the most popular iPhone replacement screens for example, there’re 4 different types of sources;
1. The original replacement screen
The main sources for original LCD screen replacements are spare inventories from original manufacturers or defective parts from original assembly lines.
2. Refurbished LCD replacement screen
The majority of damaged screens are glass-only broken screens, while the LCD display and digitizer still work. To refurbish these screens with brand new glass replacements can make them back to life and market again.
3. Flex-assembled LCD replacement screen
Apart from the original LCD assembly replacements, some original spare or defective LCD displays are seeping into the market. And some small third-party manufacturers will purchase and turn them into final replacements by assembling with new glass lens, adhesives, digitizer frames, backlight films, LCD ICs etc.
4.OEM-Compliant LCD replacement screen
The OEM-complaint replacements showed up because of the imbalance between huge demands for replacements and few original stock in availability. Comparing with the original screens, OEM-complaint ones work but still need to be improved regarding the display effect and working stability.
Judge from the market demand, the original, refurbished and flex-assembled LCD screen, which uses the original LCD, are the most needed replacement in the market. However, since last June, the original LCDs are more and more difficult to be obtained due to the strong control of original factories for the spare inventories and defective LCDs, which makes the original LCD price rises drastically and leads the repair shops and screen replacement suppliers into a dilemma. In order to meet the demands of these repair shops, the parts suppliers customized and ordered the LCDs from the Chinese factories, and assembled these China made LCD screens by third party manufacturers. Subject to cost competition, the repair shops have no choice but to purchase the China made LCD screen replacements instead.
In the long run, the price of original LCD screen will not decrease so much due to shortage of supply.
So what effects will it truly bring to repair shops when iPhone features the OLED screen?
The OLED technologies, are basically monopolized by LG and Samsung while the LCD production technology are already quite mature in China (both in high, medium and low-level). Unfortunately the Chinese LCD screen manufacturers for the time being has no technical strength to produce the small size OLED screen replacements in bulk and high standards (TM and JDF OLED product line are being under construction and pre-production, however, considering the product standard compared to iPhone, there is still a large gap). Besides, the 3D touch function of iPhone LCD screen assembly increases the technical difficulty of production. Had to say that the China made OLED screen replacements can’t meet the demands of the market in short term.
As for the third party repair shops, the refurbished LCD screen which comes from the glass-only broken LCD screen of customers, will be the major source of screen, and today is not the worst day for third party repair shops.

Analysis on: Are China made LCDs for iPhone 5S Compatible with iPhone SE?

After get the new released iPhone SE, we did a thorough study in which parts that the iPhone 5S and iPhone SE share in common (Check for more detailed information with iPhone SE Full Tear down Comparison with iPhone 5S by ETrade Supply). Not surprisingly, many replacements parts of iPhone SE are compatible with iPhone 5S, their internal structure are almost the same. What excited us most is that they can totally share the same LCD screen and digitizer assembly, which with no doubts will reduce the inventory and supply chain integration pressures of repair shops. However, with the original LCD screen is getting more and more difficult to obtained, most repair shops are usingmore replacements parts produced by third party manufacturer in China.

In order to figure out whether the iPhone 5S LCD screens produced by the third party manufacturer are compatible with iPhone SE or not, we did the following experiment in iPhone SE: 
1.Types of surveyed LCD screen: We chose 4 different LCD screen made by Chinese LCD Screen manufacturer: TM, LT, JDF and In-cell.
2. Sample number:  20 for each kind
3. The test content:  Display and touch function
And here are the results

 

What beyond our imagination is that all of the China made LCDs can act well whether on display or touch function in iPhone 5S, however, when being used in iPhone SE, there are serious problems like shaking screen, black screen, Vertical lines on display (which just like you didn't connect the LCD screen connectors well).

Why these problems happened?
First thing we need to know is the sources and production process of the China made LCDs. The TM/LT/JDF/In-cell LCDs assemblies in the market are not completely produced by the manufacturers themselves, they just provide the cut LCD screens, the rest processes are finished by the other third party manufacturers which also provide assemble the glass lensdigitizer frame, the LCD back plate shield and the LCD drive IC or and other related small parts. It is not only the LCD itself which influences the display function, the compatibility between LCD drive IC and the motherboard is also another important involving factor. In order to save costs, pursue higher profits, these third party manufacturers are using OEM-compliant LCD driving IC, which just debugged with the compatibility of 5S's motherboard, not with SE's.

In order to verify our speculation, we did another experiment:
Sample LCD screen: 10 pieces LCD screen made by In-cell
Sample device: iPhone SE
Test result: All 10 LCD screens are worked well, no shaking screen, no black screen nor  vertical lines on display appeared.

Conclusion:
Most China made LCDs are using the OEM-Compliant LCD driving IC at present. When replacing iPhone SE LCD screen with it, there is a big chance to encounter the phenomenon of shaking screen, black screen and vertical lines on display.

Suggestion:
1.Original and brand new LCD screen would be your best choice when replacing iPhone SE LCD screen, if not, the assembled original screen and original-refurbished screen are second choices.
2. If you truly want cost-effective China made LCDs, seek for reliable suppliers which uses the original LCD drive IC, such as ETrade Supply!

Why We Think China Made LCDs won’t be Blocked by Apple in the Coming iOS Updates

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:

Reason 1. There is no need for Apple to do so by affecting so much iPhones users
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?
 
Reason 2. Learn from the “History”
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.

Why this rumor came into being?
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”.

Who will get benefits from this rumor?
1.       Refurbishing Facilities/Companies
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.
 
2.       Reclamation Companies
This guys are even more sensitive to the demand and price of OEM screens. Keeping the demand at a high level means they can earn more cash.
 
3.       Those who hold plenty of 6 OEM screens at hands
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!
