Q: What is the reason of the locally yellow spot on the display screen when the capacitive screen module is in use? How to solve it?
A: The macula is caused by the local thickness change when the LCD is pressed by the external force of the structure and not yet restored. At this moment, the light passing through the lcd is also different from other area where they are not squeezed, with the long time lighting of the screen, the temperature of the area being squeezed is higher than other place, which then forms the yellow spot.
The solution to remove the macula is to find out the root cause of external force and try to get rid of it.
