Problems solved by technology

[0002] Most of the current large-size LCD panels use negative VA (Vertical Alignment, vertical alignment) liquid crystal or IPS (In-Plane Switching, in-plane switching) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has higher production efficiency And the advantage of low manufacturing cost, but compared with IPS liquid crystal technology in optica

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] Such as figure 1 As shown, the brightness of VA-type LCD driver saturates rapidly with the voltage at a large viewing angle, as shown in the attached figure 1 As shown in the L20 curve in the middle, the image quality contrast and color shift of the viewing angle are seriously deteriorated compared with the front view image quality, and the front view brightness vs. voltage curve is shown in the attached figure 1 Shown in the L10 curve.

[0042] In VA-type liquid crystal technology, in order to solve the viewing angle deviation, the sub-pixels of RGB are divided into main pixels and sub-pi...

Abstract

The invention relates to a driving method of a display panel and a display device. The driving method comprises steps as follows: pixels are divided into multiple pairs of pixel groups; a first voltage signal and a second voltage signal which are unequal and correspond to each sub-pixel are acquired, and an image input signal comprises a first image and a second image which are in the adjacent time sequence; in the first image, the first voltage signal and the second voltage signal of a first sub-pixel in each first pixel group are utilized to drive first sub-pixels of the first pixel group and the corresponding second pixel group, and the second voltage signal and the first voltage signal of a second sub-pixel of the corresponding second pixel group are utilized to drive second sub-pixels of the first pixel group and the second pixel group; in the second image, the second voltage signal and the first voltage signal of a first sub-pixel of each second pixel group are utilized to drive the first sub-pixels of the corresponding first pixel group and the second pixel group, and the first voltage signal and the second voltage signal of a second sub-pixel of the second pixel group are utilized to drive the second sub-pixels of the first pixel group and the second pixel group. The resolution is maintained, and color offset compensation effect can be realized.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a method for driving a display panel and a display device. Background technique [0002] Most of the current large-size LCD panels use negative VA (Vertical Alignment, vertical alignment) liquid crystal or IPS (In-Plane Switching, in-plane switching) liquid crystal technology. Compared with IPS liquid crystal technology, VA liquid crystal technology has higher production efficiency And the advantage of low manufacturing cost, but compared with IPS liquid crystal technology in optical properties, there are more obvious defects in optical properties, especially large-size panels require a larger viewing angle for commercial applications. [0003] The brightness of VA-type liquid crystal driver saturates rapidly with the voltage at a large viewing angle, resulting in a serious deterioration in viewing angle image quality contrast and color shift compared to the front ...
