What is a dead pixel in a mobile phone? What do you think?

The so-called "dead pixels" mean that no matter what color is displayed on the mobile phone screen, a certain point area on the screen is always the same color, and the color of the point cannot be restored, and only by replacing the new color screen can the problem be solved. Generally speaking, a "dead pixel" in a certain position of the mobile phone screen is caused by damage to the transistor at the corresponding position.
