Abstract

A method for driving a liquid crystal display panel is suitable to such liquid crystal display panel that it comprises a driving chip and a plurality of displaying unit groups having a plurality of displaying units which are connected to corresponding gate electrodes and data electrodes respectively; said driving chip drives the individual displaying units of respective displaying unit groups simultaneously. The method comprises the following steps: firstly, providing a plurality of video signals to the displaying unit groups to drive the individual displaying units, wherein the individual displaying units of the adjacent displaying unit groups receive the video signals with contrary polarities, and finally, providing the scanning signals to the gate electrodes.

Description

technical field [0001] The present invention relates to a liquid crystal display panel drive circuit and a liquid crystal display panel, in particular to a data driving method for a liquid crystal display panel that simultaneously drives its respective corresponding display units with multiple output channels of a drive chip, and proposes a A liquid crystal display panel driving circuit capable of eliminating cross-talk and a method for improving picture quality by using the driving circuit. Background technique [0002] figure 1 A schematic diagram showing an equivalent circuit of a known thin film transistor liquid crystal display panel (liquid crystal display panel, hereinafter referred to as LCD panel) and its peripheral driving circuit. As shown in the figure, the LCD panel 1 is formed by criss-crossing data electrodes (indicated by D1, D2, D3, ... Dm) and gate electrodes (indicated by G1, G2, ... Gn). Each set of interleaved data electrodes and gate electrodes can be...
