Abstract

The invention relates to the field of display, in particular to a display brightness control method and device and a display look-up table acquisition method and device. The display brightness control method comprises the following steps: acquiring an initial display look-up table of the display equipment, wherein the initial display look-up table comprises a mapping relationship between a target gray scale and an output gray scale; taking different HDR modes of the display equipment as current HDR modes, and collecting first display brightness corresponding to each output gray scale in the current HDR modes; according to the standard brightness of the target gray scale and the first display brightness corresponding to each output gray scale, updating the output gray scale corresponding to the target gray scale in the initial display look-up table to obtain a target display look-up table of the current HDR mode; and in a display stage, determining a corresponding target display look-up table according to the current HDR mode of the display equipment, and controlling the display brightness of the display equipment according to the target display look-up table.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a display brightness control method, a display brightness control device, a display lookup table acquisition method and display lookup table acquisition device, a non-volatile computer-readable storage medium, and electronic equipment. Background technique [0002] At present, terminals such as professional monitors, computers, smart phones, etc. have been widely used, and these terminals usually include a display device or the main body is a display device. Display devices generally have gamma characteristics; the gamma characteristics will affect the display effect of images. [0003] The existence of the gamma characteristic is related to the characteristics of the luminescent material of the display device and cannot be adjusted independently; therefore, when the display device displays images, it is necessary to control the display brightness of the display dev...
