How much do you know about China made LCD screen

The LCD screen can always be a fragile part compared with other parts within your phone. Once it’s cracked, you have no way but to repair it. With Apple support, you get an Original (OEM) LCD Screen with a high price. With a repair shop, you are most likely to get a China made LCD screen with a much lower price. Yes, because of the lack of iPhone original LCD screens, more and more independent repair shops have turned to China – the world’s factory for replacement parts. Tagged as less expensive than OEM products, China-made LCD screen stands for a potentially worthwhile choice.
Recently REWA has got some exclusive samples of the Tianma-made iPhone 7 LCD screen, did full tests with these samples and found some differences compared to OEM screens in the aspects of appearance, structure and function etc.
In following photos, the white color sample is Tianma-made, while the black sample is OEM.
Dimensions
From the above test data, we can observe that the screen thickness parameter is different. The Tianma-made screen is much higher than OEM screen. The reason given for it is that these two LCD screen structures are different.

Flex CableAlso affected by the difference of structure, there are some differences between Tianma-made screen flex cable lines and OEM screen flex cable veins.
The left screen is OEM, the right one is Tianma-made.

Structure
Tianma-made iPhone 7 LCD screen features with a conductive layer of ITO, while OEM screen is using an In-cell program. And this also explains the increase of screen thickness.

Tianma-made screen may be relatively falling behind in laminating technology, it proves successful on display and touches function test. The truth is that they do differ from each other, but the Tianma-made screen can also be a good replacement for OEM screen for those who want to cut repairing cost and get an affordable one.
