[0043] When driving a liquid crystal display panel, on the one hand, if the liquid crystal molecules are always driven to rotate by an electric field in the same direction, the response of the liquid crystal molecules to the electric field will gradually become dull. In order to avoid this problem, the polarity inversion driving method is adopted in liquid crystal display technology, that is, th...

Abstract

The invention discloses an array substrate, a liquid crystal display panel and a dot-inversion drive method thereof. The array substrate is provided with multiple matrix-arranged sub-pixels thereon, each sub-pixel is divided into a main region and a sub-region, and pixel voltage of the main regions is higher than that of the sub-regions in displaying a frame; the sub-pixels are configured in that when the sub-pixels are driven through positive polarity voltage, loading speed of a first load path is equal to that of a second load path and is greater than that of a third load path; when the sub-pixels are driven through negative polarity voltage, loading speed of the first load path is equal to that of the second load path and is smaller than that of the third load path. Dot-inversion drive of the liquid crystal display formed on the basis of the array substrate, the problem that pixel electrode potentials of the main regions and the sub-regions of the multi-domain structured sub-pixels are inconsistent in symmetry can be solved, and picture flicker and picture residues due to inconsistence in symmetry of the pixel electrode potentials are removed or improved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to an array substrate, a liquid crystal display panel and a dot inversion driving method thereof. Background technique [0002] The LCD panel industry has experienced decades of development. The vertical alignment VA (Vertical Alignment) display mode has become a common display mode for large-size LCD TV displays due to its advantages such as wide viewing angle, high contrast, and friction-free alignment. In order to solve the problem of large viewing angle in VA display mode, multi-domain structure design is often used as a countermeasure. [0003] In the multi-domain structure design, each sub-pixel is divided into a main area and a sub-area. When displaying a picture, the pixel voltage of the main area is higher than that of the sub-area. However, different high and low pixel voltages will lead to different feedthrough effects on the main area and the ...
