Abstract

The present invention proposes a neural network-based display device brightness compensation method, device and equipment, wherein the method includes: acquiring the image displayed by the display device to be compensated, and extracting the brightness data of each pixel in the image; The activation function processes the luminance data of each pixel to generate a compensation result, so as to adjust the display device to be compensated according to the compensation result. Therefore, by introducing a nonlinear activation function, the fitting ability is improved when performing brightness compensation on the display device, and the brightness compensation effect of the display device is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method, device and equipment for brightness compensation of a display device based on a neural network. Background technique [0002] At present, mura defects often occur in the production process of display devices due to the production process and other reasons. Among them, mura refers to the phenomenon that the brightness of the display device is uneven, resulting in various traces. When a mura defect occurs in a display device, brightness compensation needs to be performed on the display device to make the brightness of the display device uniform. [0003] When compensating the screen in the related art, the brightness compensation is usually performed through a linear or simple nonlinear model, which has limited fitting ability, and the effect of brightness compensation needs to be improved. Contents of the invention [0004] The present invention aims to solve one of ...
