Abstract

The invention relates to a liquid crystal display panel and a drive method thereof. The liquid crystal display panel comprises a plurality of pixels, wherein the pixels respectively comprise first assistant pixels and second assistant pixels. The first assistant pixels and the second assistant pixels are respectively loaded with the voltage of a source electrode according to the pulse of a first grid electrode. Moreover, the second assistant pixels comprise a first storage capacitor and a first compensation capacitor. The first storage capacitor is used for storing the voltage of the source electrode. The first compensation capacitor can be charged and discharged to preset voltage according to switching pulse. Afterwards, the first compensation capacitor can carry out charge neutralization with the first storage capacitor according to the pulse of a second grid electrode. Notably, the switching pulse, the pulse of the first grid electrode and the pulse of the second grid electrode are transmitted one by one according to a time sequence.

Description

technical field [0001] The invention relates to a liquid crystal display panel, and in particular to a liquid crystal display panel capable of eliminating residual image and uneven picture. Background technique [0002] For multi-domain vertical alignment liquid crystal displays, the alignment protrusions or slits arranged on the color filter substrate or the display element array substrate can make the liquid crystal molecules arrange in multiple directions, resulting in multiple Different alignment regions (domain), so the multi-domain vertical alignment type liquid crystal display can meet the requirement of wide viewing angle. Nevertheless, the transmittance-level curve of the multi-domain vertical alignment liquid crystal display still has different curvatures as the viewing angle changes. In other words, when the viewing angle changes, the brightness displayed by the multi-domain vertical alignment liquid crystal display will change, which will lead to color shift and...
