Problems solved by technology

For example, in a liquid crystal display panel with HSD structure, due to the different driving order of the pixel units on both sides of the data line, the delay of the data line will cause the charging difference of the pixel units on both sides of the data line in the same row, resulting in display defects of vertical bright and dark lines

Abstract

The invention discloses a method for driving an HSD liquid crystal display panel. The method comprises the steps that a sequence scanning pulse signal is provided for a grid line of the liquid crystal display panel so as to open TFT elements corresponding to pixel units in each line respectively; a square wave data signal is provided for a data line of the liquid crystal display panel so as to charge the pixel units connected with drain electrodes of the TFT elements through the square wave data signal when the TFT elements are opened, wherein the polarity of the square wave data signal reverses once every time the square wave data signal passes through 2n+1 scanning pulses, and n is an integer greater than or equal to 1. A device corresponding to the method comprises a liquid crystal display unit, a scanning drive unit, a data signal drive unit and a time sequence control unit. The method enables the pixel units with different brightness levels on the two sides of the data line to be located on the two sides of the data line in a staggered mode; staggered arrangement of the pixel units with the different brightness levels in space overcomes the display defect of perpendicular bright lines and dark lines on the panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a driving method and a device thereof for improving the display effect of an HSD structure liquid crystal display panel. Background technique [0002] The HSD pixel array shares one data line with the left and right adjacent pixel units, so that the number of data lines is halved compared with the number of data lines of the traditional liquid crystal drive pixel array. Adjacent pixel units in the same row are connected to different scan lines, and upper and lower adjacent pixel units are connected to different scan lines, which doubles the number of scan lines compared to the number of scan lines in a conventional drive pixel array. The number of pixel units connected to a scanning line is reduced, and the scanning pulse time allocated to the scanning line is reduced, so that the charging time of the pixel units is reduced, and the charging difference of the pixel...
