Reason 1: outside interference

Because strong electromagnetic interference such as electric sparks and high frequency electromagnetic fields exist near display. If interference intensity is very high, it will cause white horizontal stripes on entire display screen; if interference intensity is not strong, it will look like a serious change in a certain corner of display.

Solution: When these two situations occur, we should first focus on checking environment of display area to rule out equipment with strong magnetic interference. Generally, problem can be solved.

Reason 2: internal noise
