CHROMA ADJUSTMENT METHOD AND DEVICE FOR LIQUID CRYSTAL DISPLAY SCREEN

Document Type and Number:

WIPO Patent Application WO/2017/084424

Kind Code:

A1

Abstract:

A chroma adjustment method and device for a liquid crystal display screen. The method comprises: measuring chroma coordinates at a minimum gray-scale value and a maximum gray-scale value of a display screen to be adjusted; setting chroma coordinates of a critical gray-scale value of the display screen to be adjusted to be the chroma coordinates of the maximum gray-scale value; according to the chroma coordinates of the minimum gray-scale value and the critical gray-scale value of the display screen to be adjusted, and reference chroma coordinates between a minimum gray-scale value and a critical gray-scale value of a standard display screen, respectively calculating chroma coordinates of each gray-scale value between the minimum gray-scale value and the critical gray-scale value of the display screen to be adjusted; and according to the chroma coordinates of each gray-scale value between the minimum gray-scale value and the critical gray-scale value of the display screen to be adjusted, adjusting the chroma of the display screen to be adjusted. By means of the chroma adjustment method and device for a liquid crystal display screen, the chroma of a display screen can be automatically and accurately adjusted by utilizing an instrument, so that the chroma debugging efficiency of the display screen can be greatly improved.
