It's a screen leak.

The LCD screen is strongly squeezed by external force, and local damage will occur inside the LCD screen, and the LCD will slowly leak, which can not be seen at the time, and the appearance can be seen after a period of time.

Generally speaking, the vast majority of liquid leakage on the LCD screen is caused by external forces, and this situation will not be warranted; When using the LCD screen, do not use your hands to force the screen, do not dig up the screen stains with your hands, handle it gently, and use a special cleaning tool to clean the screen.

There are several main reasons for the leakage of the LCD screen:

Damaged seal: It will mainly appear at the four edges of the screen, if the acidic and alkaline liquid part of the drink, juice, soda, tea and other parts are carefully soaked from the edge of the external flow screen, it will cause the sealant to be damaged and the liquid crystal inside to leak.

If there is a problem with the sealant in the production process of the screen, such a failure will also occur.

The surface of the screen is damaged by external force: it is generally concentrated in the middle of the screen, and obvious traces of glass cracking can be seen.

Answer: If the edge of the mobile phone screen is black, it may be that the mobile phone is flooded, or it is broken and the screen leaks, you should clean up the infiltrated water as soon as possible or replace it with a new screen, otherwise it will not only affect the screen display, but also erode the motherboard and damage the mobile phone. It is best to send it to the after-sales service for repair, and do not deal with it yourself, so as to avoid other failures due to operation errors.

If it is a black edge on the periphery of the mobile phone screen, it is a normal phenomenon, as long as there is a digital product with a screen, including mobile phones, computers, televisions, etc., there is a black edge between the screen and the border, and its scientific name is called BM area. The main function of the BM zone is to prevent light leakage on the screen, if there is no BM zone on a screen, you will see a noticeable halo at the edge of the screen.

If the outer frame of the screen is aligned with the visual edge of the BM area, there will be a colored glare at the edge of the frame, and the mobile phone with the white border may reflect the screen light, and there will be bright edges around the screen, so the BM area must exist. Some mobile phone screens have obvious light leakage, which is caused by a large error during screen assembly and the BM area cannot be effectively blocked.
