What's Our Grades?
Grade OEM is 100% original manufactured. We get this kind of parts from the first level dealer. OEM parts are those with 100% original core components like LCD, IC chip, flex, which are assembled by the original factories.
2) Grade: OEM Refurb
The OEM screen cracked and glass lens was broken but the rest parts are still working, so the third-party factories separate glass lens from the screen and refurbish with a new one.
3) Grade: Original LCD
Only the LCD ,ic driver and flex cable is original. The rest are copy. The LCD is assembled with other spare parts like flex cable, glass lens, frame, backlight and polarize film etc. by third-party factories in the market.
4) Grade: In-Cell (LG)
It is one kind of China made LCD quality. In the market, people also call it Copy LG. Because its LCD copies LG LCD at 1:1. All of the parts are copy except IC driver. Its internal structure is the same as the original lcd (in-cell). The structure is: (LCD+TP)+ Glass. LCD and TP comes together. LCD flex and touch flex are assembled with LCD.
