Embodiment Construction

[0055] 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.

[0056]figure 1 It is the effect diagram of color shift in the prior art, such as figure 1 As shown, when the user is at position A (vertical viewing angle) and position B (oblique viewing angle), the perception is inconsistent, and when the user is at position B, the image of the liquid crystal display becomes white.

Abstract

The invention provides a method and a device for improving colour cast of display visual angles and a storage medium. The method includes the following processes: acquiring a target partition where the pixel is located, wherein the target partition is obtained by pre-dividing a display area; and performing display compensation on the pixel according to a gamma correction parameter corresponding tothe target partition. By the method and the device, the problem of colour cast of a display area from different display visual angles is solved by different display compensations of pixels at different positions, and the effect that the viewing impressions from different display visual angles are consistent is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of liquid crystal display, and in particular to a method, device and storage medium for improving display viewing angle deviation. Background technique [0002] Color cast means that in the captured or displayed image, the hue and saturation of a certain color are obviously different from the real image. Most liquid crystal displays use light-emitting diodes as the backlight source. Among the white light emitted by the liquid crystal display, the characteristic wavelengths of red light, green light, and blue light are inconsistent. This results in the existence of color cast under different display viewing angles, that is, when the viewing angles and positions of the observers are different, the display effect of the liquid crystal display is different, and the image under the oblique viewing angle is white, and the The size of liquid crystal displays is getting larger and larger, and ...
