Apple launched the most expensive cellphone iPhone X last year, the price starts at $999. The OLED screen used makes the price of iPhone X much higher than other iPhone that with the LCD screen. But to reduce the iPhone X screen repair cost, the aftermarket LCD screen has come out by the Chinese factory. Here let’s check the difference between OEM and aftermarket iPhone X screen.

1. Comparing the appearance

At many times, we can distinguish the OEM and aftermarket iPhone screen through the appearance. Here we compared 3pcs iPhone X screen, 1pcs OEM screen and 2pcs aftermarket screens.

Comparing from the front, there is no obvious difference between aftermarket and OEM screen.

Comparing the back of the screen, the aftermarket doesn’t have connector contacts, which may have an impact on the signal.

2. Comparing the thickness

The aftermarket screen looks thicker than the OEM which will have an impact on the appearance after installation.

We measured 4 corners of the three screen and got a table list:


Upper Left Upper Right Lower Right Left Lower






Aftermarket 1





Aftermarket 2





Through the table, we can find that the aftermarket screen is about 0.4-0.5mm thicker than OEM screen. After installation, we measured the top and bottom of each device, both of the devices with aftermarket screen are thicker than OEM one. The device with aftermarket screen is about 0.3mm thicker on the top and 0.4-0.5mm on the bottom than the device with OEM screen.

3. Testing screen function

The display is an important part of the iPhone, here we will test the Auto-brightness, Face ID, 3D Touch, screen touch and color display.

a. Testing auto-brightness

The auto-brightness function of aftermarket screen is disabled after installation. While it works well on OEM screen is because its data are linked with original motherboard.

b. Testing Face ID

We tested the Face ID function of 3 screens on the same motherboard, all of them working well. This also verifies that changing the screen of iPhone X does not affect the Face ID function.

c. Testing 3D Touch

The 3D touch works well only in the partial area of the aftermarket 1 screen. Comparing to the OEM screen, it should be pressed with longer time and more pressure.

While the aftermarket 2 screen doesn’t have 3D Touch function at all.

In general, the 3D touch function on the aftermarket screen is failed now, but we think it will be better in the future and we will keep tracking it.
