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 Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below with examples in conjunction with the accompanying drawings.

[0034] refer to figure 1 , a traditional liquid crystal panel mainly includes a display area 1 with a plurality of pixel units 5a, 5b, a gate controller 2 and a source controller 3, and the gate controller 2 provides the pixel units 5a, 5b with multiple scan lines For scanning signals, the source controller 3 provides data signals to the pixel units 5a, 5b through a plurality of data lines. Wherein, each pixel unit 5 a, 5 b includes a red sub-pixel 51 , a green sub-pixel 52 and a blue sub-pixel 53 .

[0035] The purpose of this embodiment is to simulate the display of a 2D1G panel in the traditional RGB three-pixel liquid crystal panel by changing the driving method of the liquid crystal panel, so as to reduce the problem of color shift when viewed sideways o...

Abstract

The invention discloses a driving method of a liquid crystal panel. The driving method comprises the following steps: providing the liquid crystal panel, wherein the liquid crystal panel comprises a plurality of pixel units, and each pixel unit at least comprises blue sub-pixels; dividing the liquid crystal panel into a plurality of display units, wherein each display unit comprises a first pixel unit and a second pixel unit which are adjacent to each other; providing gray-scale values BH for the blue sub-pixels in the first pixel units for blue sub-pixel gray-scale values B needed by the display units, and providing gray-scale values BL for the blue sub-pixels in the second pixel units, wherein the gray-scale values BH and BL are combined, so that the brightness curve of the blue sub-pixels of the display units at an inclination angle tends to be a predetermined Gamma curve, and Gamma is equal to 1.8-2.4. The invention further discloses the liquid crystal panel driven by using the driving 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...
