Embodiments of the present invention provide a method and device for determining a compensated gray scale value of a display panel, and a display device, which relate to the field of display technology and can reduce storage space required for compensation gray scale value data, thereby reducing costs. The method for determining the compensated gray-scale value of the display panel includes: searching the gray-scale digit judgment value corresponding to the sub-pixel to be compensated in the gray-scale digit judgment value table, and if the gray-scale digit judgment value satisfies the gray-scale digit condition, then Determine the compensated gray scale value corresponding to the sub-pixel to be compensated by the first reading method, if the gray-scale digit judgment value does not meet the gray-scale digit condition, determine the compensation corresponding to the sub-pixel to be compensated by the second read method grayscale value.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a method and device for determining a compensated gray scale value of a display panel, and a display device. Background technique [0002] At present, after the display panel is manufactured, it is usually necessary to carry out optical inspection first, and then set the compensated grayscale value for each sub-pixel according to the result of the optical inspection, and then save the preset compensated grayscale value data in the memory, and then , when the display panel is working normally, the compensated gray scale value corresponding to each sub-pixel will be read from the memory, and the original gray scale data of the sub-pixel will be compensated according to the compensated gray scale value, and realized according to the compensated gray scale value data. The sub-pixels are driven to improve the display effect of the display screen by means of gray scale value c...
