Abstract

The embodiment of the invention discloses a display screen correction coefficient correction method, a display screen bright spot correction device, a display screen correction coefficient correctionsystem and a computer readable medium. The method comprises the following steps: reading a correction coefficient of a display screen and obtaining a correction coefficient threshold of the display screen according to the correction coefficient; generating a display screen simulation diagram corresponding to the display screen according to the correction coefficient; sending the preset image to adisplay screen and displaying the preset image; responding to a first operation instruction of a user based on the abnormal lamp points displayed on the display screen so as to obtain an abnormal lamppoint area containing the abnormal lamp points in the display screen through the display screen simulation diagram; correcting the correction coefficient of the abnormal lamp point area according tothe correction coefficient threshold to obtain a corrected correction coefficient of the abnormal lamp point area; and updating the correction coefficient of the display screen according to the corrected correction coefficient to obtain the updated correction coefficient of the display screen. According to the embodiment of the invention, the correction coefficient of the display screen correctedby the camera with dirty spots can be quickly corrected, and time and labor cost are saved.

Description

technical field [0001] The present invention relates to the technical field of display control, in particular to a display screen correction coefficient correction method, a display screen bright spot correction device, a display screen correction coefficient correction system and a computer-readable medium. Background technique [0002] With the continuous development of the display screen market, the market has higher and higher requirements on the display quality of the display screens, such as LED display screens. The LED display screen can use professional calibration software to calibrate its brightness and chromaticity before and after leaving the factory to ensure the uniformity of the screen display. At present, the display quality of the LED display is mainly improved through the method of acquisition and correction. It collects the brightness and chromaticity information of the LED display through the camera, and calculates the brightness and chromaticity differen...
