What is OEM, Grade B, Grade C and Custom?

OEM: original equipment manufacturer. According to wikipedia, an original equipment manufacturer is a company that produces parts and equipment that may be marketed by another manufacturer. Technically speaking, OEM screen will work just like the original screen.

Custom: original digitizer with replaced front glass. The front glass of original Pixel 2 XL is made of Corning Gorilla Glass 5, while the custom screen equipped with normal glass.

Grade B: factory defects. We all know that Pixel 2 XL has P-OLED screen, and P-OLED means plastic OLED, it is more durable than typical AMOLED. The flexibility of plastic gives some additional shock absorbance over glass. This durability also means POLED is less susceptible to cracking and shattering from dropping, which means the possibility of shipping damage is infinitesimal. So why does there grade B exist? They can only be the factory defective products.

Grade C: original worn screen with a lot scratches on front glass. The display of grade C is took from worn Pixel 2 XL phones and the glass is damaged.

How to spot OEM, Garde B and Grade C?

  1. Black display or off screen

OEM screen will perfectly work just like the original one after repaired, while the grade B has some defective mark on the screen. The marks are usually a cross or a arc-shaped, it’s obvious seen from the plate angle of view, when the screen is black.oem vs grade b -2oem vs grade b -3

2.White display

Some grade B screen have visible black spot when the screen is white, it was caused by some LED inside the display damaged. All of the panels are built from millions of organic light emitting diodes, tiny little components that light up when current is applied to them. If the organic light emitting diodes damaged, it will shut down and that’s why there’s black spot on white screen.oem vs grade b 3oem vs grade b 2
