Problems solved by technology

However, after each pixel unit is divided into the main pixel area and the sub-pixel area, the number of data lines for inputting data signals is doubled, which will greatly reduce the aperture ratio of the liquid crystal panel and affect the transmittance. , which reduces the display quality of the LCD panel

Embodiment approach

[0064] (1) Arranging the first pixel unit 5a and the second pixel unit 5b in pixel units in two adjacent rows and two adjacent columns. Specifically, such as Figure 5 As shown, the first pixel unit 5a is the pixel unit in the mth row and the nth column, and the second pixel unit 5b is the pixel unit in the m+1th row and the n+1th column. These two pixel units form a display unit ; and the two pixel units in row m+1, column n and row m, column n+1 form another display unit. The blue sub-pixel in the pixel unit in the mth row and nth column inputs a higher grayscale value BH1, and the blue subpixel in the m+1th row and n+1th column inputs a lower grayscale value BL1; the other In the display unit, the middle blue sub-pixel in the m+1th row and nth column inputs a higher grayscale value BH2, and the pixel unit in the mth row and n+1th column inputs a lower grayscale value BL2; where m=1 , 3, 5, ..., M, n=1, 3, 5, ..., N.

Abstract

The invention discloses a driving method for a liquid crystal panel, and provides the liquid crystal panel. The liquid crystal panel comprises M*N pixel units, and each pixel unit comprises a blue sub-pixel. The liquid crystal panel is divided into a plurality of display units, and each display unit comprises two pixel units. The gray scale values B of blue sub-pixels needed by the display units are respectively divided into a higher-order gray scale value BH and a lower-order gray scale value BL, which are respectively provided for two pixel units. The combination of the higher-order gray scale values BH and the lower-order gray scale values BL enables the brightness curve of the blue sub-pixels of the display units at a squint angle to approach a preset Gamma (gamma) curve, wherein gamma is from 1.8 to 2.4. The invention also discloses the liquid crystal panel driven through the above method.

Description

technical field [0001] The invention 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 suffers from color...
