Abstract

The invention provides a method for adjusting a display screen of a display device. The method for adjusting the display screen of the display device comprises the following steps: acquiring a color abnormal area in the display screen of the display device; obtaining actual gray scale ranges corresponding to the three colors of red, green and blue in the color abnormal area; judging the abnormal color of the color abnormal area, obtaining the adjusted gray scale range according to the actual gray scale range corresponding to the abnormal color, then adjusting the brightness of the gray scale in the adjusted gray scale range corresponding to the display device to eliminate the color abnormal area in the display image, and the display quality of the display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for adjusting a display screen of a display device. Background technique [0002] In the field of display technology, flat panel display devices such as Liquid Crystal Display (LCD) and Organic Light Emitting Display (OLED) have gradually replaced cathode ray tube (CRT) display devices. The liquid crystal display device has many advantages such as a thin body, power saving, and no radiation, and has been widely used. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel consists of a color filter (Color Filter, CF) substrate, a thin film transistor (Thin Film Transistor, TFT) array substrate, a liquid crystal (Liquid Crystal, LC) and a sealant sandwiched between the color filter substrate and ...
