In Union Repair store, we grade our iPhone screen into 5 different types of quality on the basis of different material assembled. The following is the full details of each condition.
After Market Basic
It is with widely accept major complaint replacements for original parts, which keeps a right balance between price and quality. It has sustainable supplying chain in China, and all the components of the screen are copy quality. Typically, the LCD screen is from several different factories, the most popular 4 on China market are JK,AUO, LongTeng, and ShenChao. By comparing the brightness and sharpness of the LCD, we found JK is the best quality among them and the second best is AUO. No doubt, the other components on the screen are all copy.
After Market Standard
It is better than After Market Basic cause it comes with original laminated flexes and the LCD panel. Other components like touch panel, frame(hot pressed), backlight, polarize lens, and OCA is all copy from different factories.
After Market Selected
The core components (like LCD and flexes) is 100% original pulled from used iPhone while the frame and touch panel is copy. The touch panel and frame come together with cold pressed glue and assembled together with the LCD by the capable third-party factory which keeps its excellent quality.
Original Pulls
No doubt, it is tear down from used iPhone with all the parts 100% original and working perfectly just like an original new screen, it has whatever the original new screen has. The only complaint about this quality is that some of the displays are with 1 or 2 scratches but still be welcome by our critical customers who are requiring good quality.
Original New
It is 100% original from Apple-authorized factories like Toshiba, Sharp, and LG. We get this kind of screen from the first level dealer. The touch panel of the screen is oleophobic coated which prevents from fingerprints when using your iPhone. And starting with iPhone 7g, the backlight from different authorized factories comes with a different code. Backlight from Sharp has the code begins with DKH/CON, from Toshiba begins with C11/F7C/FZQ, from LG begins with DTP/C3F.
