Problems solved by technology
[0003] At present, lighting up the same area of the display screen for a long time will cause excessive pressure on the pixels corresponding to the area, and the pixels will deteriorate rapidly. The pressure difference accumulated on the pixels for a long time will lead to differences in the degree of degradation of individual pixels, resulting in differences that can be captured by the human eye. The brightness is poor, and the display screen has an afterimage display effect, which affects the user's viewing experience

The invention discloses a compensation adjusting device and a compensation adjusting method of a display screen, the compensation adjusting device comprises a plurality of detection modules, the detection modules are respectively arranged corresponding to sub-pixels in the display screen, and the detection modules are used for detecting brightness parameters of the corresponding sub-pixels. The invention also comprises a degration information read-write board and a processing terminal. The display screen comprises a screen driving board, and the processing terminal is used for reading brightness parameters through the degradation information read-write board and the screen driving board, generating screening compensation data according to the brightness parameters and the initial brightness parameters of the corresponding sub-pixels, and transmitting the screening compensation data to the screen driving board through the degradation information read-write board; and the screen drivingboard is used for adjusting pixel data output to the corresponding sub-pixels in the display screen according to the received screening compensation data and the received display data. By means of thetechnical scheme, display ghosting existing in the display screen is eliminated, and the service life of a screen body of the display screen is greatly prolonged.
Description
technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a compensation adjustment device and a compensation adjustment method for a display screen. Background technique [0002] With the development of display technology, the types of display screens are gradually increasing, and users have higher and higher requirements on the display effect of the display screen, such as display parameters such as display color and display saturation of the display screen. [0003] At present, lighting up the same area of the display screen for a long time will cause excessive pressure on the pixels corresponding to the area, and the pixels will deteriorate rapidly. The pressure difference accumulated on the pixels for a long time will lead to differences in the degree of degradation of individual pixels, resulting in differences that can be captured by the human eye. The brightness is poor, and the display screen h...
