SCR TFT In-cell and TFT Out-cell Screen Comparison Test

Recently, some customers have reported that there are many different quality iPhone X to 11 series aftermarket screens in the market and they don't know the difference between them. For example, there are soft OLED, hard OLED, TFT in-cell, TFT out-cell, etc., among which, TFT is cheaper and is shipped in larger quantities than the others. Therefore, in this article, we will compare the difference between SCRCTECH SCR TFT in-cell and TFT out-cell iPhone 11 LCD.

For the structure, brightness, color temperature, display color, installation effect and defect rate , we did a rigorous comparison test, the specific test results are as follows.

The brightness of the in-cell is better than the original while the brightness of the out-cell is lower than the original. It means that the TFT in-cell display effect is better than the out-cell LCD. The color temperature of the in-cell is also better than that of the out-cell LCD. 

As the pictures show, the color effect of the TFT in-cell is much better than the out-cell.

The thickness of the TFT in-cell is the same as the original. And the thickness of TFT out-cell is thicker than the original .
Defect Rate Problem

The defect rate of out-cell TFT is high due to the LCD structure. The out-cell structure is COG and G+G which means the touch panel is made of glass and the IC is on the glass. The original is COF and G+F structure. The touch panel is made of film and the IC is on the FPC. From our after-sales data, the eliminated TFTs have some failure problems,such as tapping the screen does not wake up the screen;the glass frame of the cover comes off, and other touch function problems.The defect rate is from 25%-100%. Some touch issues will be found after a period of use.
 
From the test results, we can see that TFT out-cell is cheaper than the in-cell, but the display effect and functional stability are worse than the in-cell. TFT out-cell is suitable for those who only pursue low price. For those who have certain requirements for quality, it is better to choose TFT in-cell.
