Problems solved by technology
For example, the backlight module of the liquid crystal display screen for learning is provided with a light guide plate. Due to the light-gathering effect of the light-emitting microstructure on the light-emitting surface of the light guide plate, the light at the corner of the light guide plate is relatively dark, so that the corners of the display screen The light is dim, which affects the display effect
