Because of the huge demands for different mobile phone screens in the aftermarket, as well as the reduction of raw materials and supplies, the phenomenon of using TFT in-cell screens to pretend to be OLED in-cell screens have appeared in the aftermarket. Therefore, it is necessary to learn to distinguish between these two screens.

Today, we conducted a detailed test on these two qualities, the differences of them are as below:

Overall thickness: the thickness of the TFT In-Cell screen is 2.26mm, while the OLED In-Cell screen is 1.71mm. Obviously, the overall thickness of the OLED In-Cell screen is much thinner than the TFT In-Cell screen.

Corner’s thickness: the thickness of the screen at the corners of the mobile phone is different. The thickness of the three corners of the OLED In-Cell screen are: 1.64mm, 1.67mm,2.38mm, the thickness of the three corners of the TFT In-Cell screen are: 2.28mm, 2.29mm, 3.44mm. Obviously, the thickness of the three corners of the OLED In-Cell screen is much thinner than the TFT In-Cell screen.

OLED In-Cell screen has no backlight layer while TFT In-Cell screen has a backlight layer. This is why the overall thickness of the TFT In-Cell screen and the thickness of the three corners are thicker than those of the OLED In-Cell screen.

The color saturation of the OLED In-Cell screen is higher than those in the TFT In-Cell screen.

After the 360° Visibility Test, we can see that the display on the OLED In-Cell screen edge is much clearer. So, compare to the TFT In-Cell screen, the OLED In-Cell screen has higher visibility.

After the comparison, we found that the water drops don’t spread into larger spots on the OLED In-Cell screen and the water drops spread into larger spots on the TFT In-Cell screen. So, the oleophobic coating effect is better on the OLED In-Cell screen

The pixel arrangement of TFT is RGB arrangement, while OLED is RGB Pentile arrangement, Due to this, the pixel arrangement of OLED In-Cell screen will be neater and more orderly than TFT In-Cell screen, and the pixel points will be clearer and more diverse. This is the reason for the higher display degree and higher color saturation of the OLED In-Cell screen.

Conclusion

The difference between OLED In-Cell screen and TFT In-Cell screen is mainly whether there is a backlight layer that determined the screen’s thickness, and then the pixel arrangement which determined color display and visibility.
