Problems solved by technology

[0004] In view of this, the object of the present invention is to provide a liquid crystal panel and its driving method. By changing the driving method of the liquid crystal panel, the display of the 2D1G panel can be simulated in the traditional RGB three-pixel liquid crystal panel, so as to overcome the color generated when viewed from the side or obliquely. In addition, it also overcomes the problem of unsmooth changes in fine images caused by excessive brightness differences caused by simply dividing all blue sub-pixel units for higher grayscale value / lower grayscale value driving

Abstract

The invention discloses a liquid-crystal panel and a drive method therefor. The method comprises the steps: providing the liquid-crystal panel, wherein the liquid-crystal panel comprises an M*N pixel unit matrix and each pixel unit sequentially consists of a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit, thereby enabling the liquid-crystal panel to comprise an M*(3*N) sub-pixel unit matrix; performing dividing operation for the sub-pixel unit matrix; providing a higher-gray-scale-value BH for the first sub-pixel unit in the sub-pixel unit of each color; providing a lower-gray-scale-value BL for the second blue sub-pixel unit in the sub-pixel unit of each color; and enabling the brightness curve of the sub-pixel unit of each color at an inclined angle to approach a preset Gamma curve. According to the invention, the color bias, generated when a user watch the liquid crystal display from a side or at an inclined angle, can be reduced.

Description

technical field [0001] The present invention generally relates to the technical field of liquid crystal displays, in particular to a liquid crystal panel and a driving method thereof. Background technique [0002] Liquid crystal display, or LCD (Liquid Crystal Display), is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of a light source or a reflector. Liquid crystal displays have low power consumption, high image quality, small size, and light weight, so they are favored by everyone and become the mainstream of displays. Liquid crystal displays have been widely used in various electronic products, such as computer equipment with display screens, mobile phones, or digital photo frames, etc., and wide viewing angle technology is currently one of the development focuses of liquid crystal displays. However, when viewed sideways or obliquely, the liquid crystal display with a wide viewing angle often ...
