Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0062] As mentioned in the background art, in the prior art, after the brightness of the display panel is adjusted, the Mura compensation effect is poor, and the display uniformity of the display panel is poor. The inventors have found through research that the reason for the above problems is that in the prior art, cameras are usually used to compensate for Mura. Specifically, when the display brightness corresponding to the maximum gray scale of the display panel is the first brightness, the compensation for Mura...

Abstract

The embodiment of the invention discloses a gray scale compensation calculation method and device and a display device. An original input gray scale is converted into an input gray scale under an input display brightness instruction value; determining a second compensation gray scale corresponding to the input gray scale converted under the input display brightness instruction value, fitting according to the at least three original input gray scales and the second compensation gray scales corresponding to the at least three original input gray scales under the input display brightness instruction value to obtain a second function relation between the original input gray scales and the second compensation gray scales under the input display brightness instruction value; according to the technical scheme, the influence of the brightness level (corresponding to the display brightness instruction value) on the Mura compensation effect is considered, so that the corresponding second function relations under different display brightness instructions can be different, the Mura compensation effect can be improved, and the display uniformity is improved. And the calculation method is simple, and the mura compensation time can be shortened.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a gray scale compensation calculation method, device and display device. Background technique [0002] With the development of display technology, people have higher and higher requirements for picture display quality. [0003] Existing organic light emitting display panels generally include a plurality of sub-pixels, and when performing picture display, corresponding data needs to be provided to each sub-pixel to realize display of different gray scales. Due to the material process and other reasons, some products may have uneven screen display brightness (Mura). In the prior art, a demura device including a camera is usually used to compensate for mura. [0004] However, in the prior art, the Mura compensation effect is poor after the brightness of the display panel is adjusted, and the display uniformity of the display panel is poor. Contents of...
