Abstract:Without blue light,it is always fully yellow,when the recent LED super-scalecolor screen is used to display moving pictures and TV programs.The hue of tlie screen is toobad.This paper proposed that the surface of the screen should be blue but not black.Then itis exposed with a blue compensation light. So that the color hue of the whole screen can bewell improved.Viewing test shows that the effectiveness of the blue compensation is obvi- ous
