Display control method and device, controller and storage medium

Abstract

The embodiment of the invention provides a display control method and device, a controller and a storage medium. The method comprises the steps: acquiring a pre-stored first color compensation table and a pre-stored second color compensation table, wherein the attributes of the pixel compensation values corresponding to the same positions in the first color compensation table and the second colorcompensation table are different, and the attributes of the pixel compensation values comprise the attribute of brightening original pixels and the attribute of darkening the original pixels; and switching the first color compensation table and the second color compensation table according to a preset rule, and performing color cast compensation on a display picture by adopting the switched current color compensation table. According to the embodiment of the invention, each pixel of the display picture generates mixed light (brightening and darkening mixing) in the time domain, so that the problem of mosaic of the front view angle picture due to darkening of part of the pixels of the display picture is avoided, and the effect of improving the display quality of the front view angle pictureis achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display devices, and in particular, to a display control method, device, controller, and storage medium. Background technique [0002] A liquid crystal display device is generally composed of optical components such as a liquid crystal panel, and is currently widely used in liquid crystal televisions, computers, and the like. [0003] In a liquid crystal display device using VA (Vertical Alignment or Vertically Aligned, vertical alignment) mode, there is a phenomenon that the gamma characteristics of the oblique viewing angle are greatly changed (the problem of gamma shift or gamma shifting), resulting in the image of the oblique viewing angle. Quality resolution is poor. At present, to solve this problem, the color cast improvement algorithm is mainly used to compensate the resolution of the image quality of oblique viewing angles. [0004] However, the existing color cast impro...
