Abstract

The invention discloses a method for eliminating a cross effect and a liquid crystal display device, and belongs to the technical field of liquid crystal. A com line of a block code display part and a com line of a dot matrix display part of a liquid crystal display screen are separately driven, and a seg line of the block code display part and a seg line of the dot matrix display part of the liquid crystal display screen are separately driven. By the method, the bad phenomenon of the display cross effect can be effectively eliminated, and the problem of poor display effect of the liquid crystal display device is solved. The method is simple and practical and cannot increase the cost.

Description

technical field

[0001] The invention relates to a liquid crystal display device, which belongs to the technical field of liquid crystal display, in particular to a method for eliminating cross effects and a liquid crystal display device. Background technique

[0002] In the dynamic driving mode, the display effect of a certain liquid crystal pixel (selection point) is realized by combining the selection voltage applied to the row electrode and the selection voltage applied to the column electrode. The pixels not in the same row and the same column as the pixel (non-selected point) are in the non-selected state, and the pixels in the same row or the same column as the pixel have a selection voltage added, which is called a half-selected point. When the electric field voltage is near the threshold voltage of the liquid crystal, there will be an undesired half-display phenomenon on the screen, which will reduce the display contrast. This phenomenon is called crossover effect. ...
