When the mobile phone changes to the external screen, does it press the screen?

Generally speaking, changing the external screen is the back screen, that is, sticking a new external screen on your previous LCD screen. Or your screen is broken, and the maintenance personnel put the broken screen together, which is also the back screen. Very few rear pressure screens will have hydrology after installation and opening, and the screen color will be cold. The original is more wear-resistant, but the back pressure is not wear-resistant. Putting a film on it basically makes no difference.

"Back pressure screen" refers to taking out the undamaged LCD layer and touch layer from the worn screen, and then pressing on a new glass panel. As the core components of this mobile phone screen, the liquid crystal display layer and the touch layer are mostly original parts, but the quality of the back screen is uneven due to the different glue quality and process flow during the pressing process. Many mobile phone repair points require customers to leave the original screen of the mobile phone, also in order to get related parts.
