Problems solved by technology

In the case of high grayscale input, the Mura compensation effect is obvious. However, in the case of low grayscale input, if the same compensation parameters are used as the high grayscale input, compensation overflow will occur, resulting in low grayscale input. OLED Display panel exhibits abnormal brightness

Abstract

The invention relates to the field of display technologies, and especially to a gamma correction method and a device for an OLED display panel, and a computer-readable storage medium and electronic equipment for implementing the above method. The method includes the following processes: obtaining a gamma curve to be corrected of an OLED (organic light emitting diode) display panel; acquiring a first compensation parameter according to the gamma curve to be corrected and a standard gamma curve; and compensating an input gray scale (which is less than a first input gray scale) of the gamma curveto be corrected by using a second compensation parameter which is less than the first compensation parameter, wherein the first input gray scale is in the low gray scale. In the technical scheme provided by the invention, the compensation overflow phenomenon occurring in the related techniques is avoided by flexibly adjusting the compensation parameter. Thereby, display brightness of the OLED display panel is uniform regardless of high gray scale input or low gray scale input, which helps improve display quality of the OLED display panel and then enhances the user experience.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a gamma correction method for an OLED display panel, a gamma correction device for an OLED display panel, and a gamma correction device for realizing the OLED display panel. Computer-readable storage medium and electronic device for horse correction method. Background technique [0002] Since each pixel in an OLED display panel has a self-luminous feature, inconsistencies between pixels are inevitable. Thus making mura a potential side effect in the OLED display panel manufacturing process. Among them, mura is an English word derived from Japanese, which means unevenness, inconsistency or blemish. In the field of display, Mura can be used to express uneven brightness display and "cloud spot" effect in OLED display panels. [0003] In view of the above problems, the related art provides a Demura solution, which corrects or compensates the gamma curve by setting co...
