Abstract

The invention provides a driving method for a liquid crystal display device and includes the following steps: firstly, the liquid crystal display device comprising a plurality of pixels which are arrangement in matrix; secondly, the polarity of voltage loaded by only one pixel in four which are included in one 2*2 submatrix in the matrix of the pixels is changed in any two adjacent frames; and thirdly, the polarity of voltage loaded by any pixel in the matrix of the pixel is invariable in four continuous frames.

Description

technical field [0001] The invention relates to a method for driving a liquid crystal display device. Background technique [0002] In a thin film transistor liquid crystal display, image display is achieved by changing the voltage applied to each pixel to change the electric field on both sides of the liquid crystal molecules corresponding to the pixel area to control its twist angle, and then control the amount of light passing through. . However, liquid crystal molecules have such a characteristic: if the direction of the electric field loaded on both sides of the liquid crystal layer remains unchanged for a long time, the physical properties of the liquid crystal molecules will be destroyed, that is, they can no longer rotate according to the change of the electric field. Therefore, it is necessary to change the direction of the electric field applied on both sides of the liquid crystal layer at regular intervals, so that the liquid crystal molecules are alternately def...
