It belongs to screen burning, which is irreversible damage. The preventive measure is to turn down the brightness of the mobile phone. Use static interfaces as little as possible.
When using a mobile phone every day, it is recommended not to adjust the screen brightness to the highest brightness for a long time and stay in the same picture for a long time.
Daily small details of mobile phone touch screen maintenance
1, the screen can't get wet.
In daily life, we are always used to keeping our mobile phones with us, including when washing in the morning, when making a phone call, our hands are still wet and we have already answered the phone. Of course, once or twice may be nothing, but these are small details accumulated, which will cause hidden dangers after a long time. The presence of water on the screen will lead to the formation of a conductive layer, resulting in a beautiful screen.
Step 2 avoid static electricity
Static electricity can easily break through the capacitive screen. Although the glass on the surface of the mobile phone screen has undergone certain anti-static treatment, it does not mean that it can withstand the static electricity of the human body. Many friends are used to sticking some decorations or inferior screen films that are easy to generate static electricity on the surface of mobile phones, resulting in screen failure. Therefore, I hope that the mobile phone can be equipped with a shell or holster if possible.
Step 3 stay away from high temperatures
Everyone should know that mobile phones are afraid of high temperature, especially Android smartphones. For example, you can't use your mobile phone for a long time in strong sunlight. If you feel very hot when playing mobile phones, especially when playing some big games, you should stop playing mobile phones as soon as possible and put them on cool and hard materials to wait for the temperature to drop.
