Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] Color shift improvement algorithm, when compensating the resolution of the image quality of oblique viewing angles, only one color compensation table is used for color shift compensation of each frame of the display screen, because only one fixed color compensation table is used, It will darken some pixels of the display screen, causing mos...

Abstract

An embodiment of the present invention provides a display control method, device, controller, and storage medium. The method includes: acquiring a pre-stored first color compensation table and a second color compensation table; wherein, the first color compensation table and the second color compensation table The attributes of the pixel compensation value corresponding to the same position in the table are different, wherein the attribute of the pixel compensation value includes the attribute of brightening the original pixel and the attribute of darkening the original pixel; switch the first color according to the preset rule The compensation table and the second color compensation table use the switched current color compensation table to perform color shift compensation on the display screen. The embodiment of the present invention enables each pixel of the display screen to generate mixed light (brightening and darkening) in the time domain, avoiding the problem of mosaic in the front view screen caused by darkening some pixels of the display screen, and improving the front view screen. Shows the effect of quality.

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 improve...
