Abstract

The invention discloses a display device brightness compensation lookup table generation method, a display device and a display device brightness compensation lookup table generation device. The method comprises a parameter reading step, an initial gray scale brightness detection step, a compensation area brightness detection step, a compensation data acquisition step and a compensation lookup table generation step. According to the method and the device, the technical problems that the overall uniformity of the brightness and the chromaticity of the display panel cannot reach the expected level and the brightness of the edge area of the display panel is darker than that of the central area, so that the brightness and the color of the display panel are not uniform, and the quality of the panel is poor are solved.

Description

technical field [0001] The present application relates to the field of display panels, in particular to a method for generating a brightness compensation lookup table for a display device, a device thereof, and a display device. Background technique [0002] Whether it is a thin film transistor liquid crystal display panel (Thin Film Transistor Liquid Crystal Display Panel, TFT-LCD) or an organic light emitting diode (Organic Light Emitting Diode, OLED) display panel, in the manufacturing process, there will inevitably be brightness uniformity, color The question of uniformity. Especially as the size of the panel becomes larger and larger, the problems of uneven brightness and uneven color become more and more common. For this reason, the Demura technology for eliminating the phenomenon of uneven display brightness has emerged as the times require. [0003] One of the speckle reduction techniques is White Tracking (WT) or white tracking technique. White balance is a very ...
