Abstract

The invention provides an image gray scale regulating method, which comprises the following steps of according to a preset gray scale, selecting a first contrast pixel unit in a first pixel unit and selecting a second contract pixel unit in a second pixel unit; obtaining the first gray scale brightness of the first contract pixel unit and the second gray scale brightness of the second contrast pixel unit; obtaining driving voltage differences of the first contrast pixel unit and the second contrast pixel unit with the same preset gray scale according to the first gray scale brightness of the first contrast pixel unit and the second gray scale brightness of the second contrast pixel unit with the same preset gray scales; obtaining a corresponding gray scale compensation value according to the driving voltage differences,; performing image gray scale regulation on the pixel unit of a liquid crystal display panel according to the gray scale compensation value. The invention also provides an image gray scale regulating device. The display gray scale regulating method and regulating device provided by the invention have the advantage that the display effect of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the field of display driving, in particular to a display gray scale adjustment method and adjustment device. Background technique [0002] With the development of TFT technology, the market has higher and higher requirements on the display effect of liquid crystal display panels. High-resolution, large-size products have gradually gained the favor of the market. The resolution ranges from 1920*1080 to 3840*2160 to 8K4K, and it is more likely to develop to 10K in the future. The sizes range from 32 inches, 40 inches, 55 inches to 110 inches and so on. [0003] Due to the large size and high resolution display screen, general use figure 1 In the pixel driving structure shown, 11 is the first data line driving circuit, 12 is the second data line driving circuit, 13 is the first scanning line driving circuit, and 14 is the second scanning line driving circuit, wherein the first data line driving The circuit 11 and the first sca...
