Abstract

The invention provides a driving method and a driving circuit for a display panel, and a display device. The display panel comprises Y grid lines. According to the scanning sequence of the grid lines, the Y grid lines are divided into multiple grid line groups. Each grid line group comprises at least one grid line. The driving method comprises steps of determining the i-th grid line to be scanned; adjusting the original charging time of the scanning signal corresponding to the i-th grid line to an adjusted charging time, wherein the adjusted charging line corresponding to each grid line in each grid line group is equal, and in a direction gradually away from the source drive, the adjusted charging time corresponding to each grid line group is gradually increased; and based on the adjusted charging time corresponding to the i-th grid line, outputting the scanning signal corresponding to the i-th grid line to the i-th grid line. The charging time corresponding to each grid line is adjusted, the charging rate of the pixel line with the insufficient charging rate is improved, and the charging rate of each line of pixels is enabled to be equal or close.

Description

technical field [0001] The invention relates to the field of display technology, and in particular designs a driving method, a driving circuit and a display device of a display panel. Background technique [0002] Such as figure 1 As shown, the liquid crystal display device includes a timing controller (TCON), a source driver (Source Driver), a gate driver (Gate Driver), and a display panel. Wherein, the display panel is provided with vertical data lines (not shown) and horizontal gate lines (not shown), and a pixel array (not shown) located in the pixel area defined by the data lines and the gate lines . The timing controller is used to output the clock signal CPV, the enable signal OE and the frame trigger signal STV to the gate driver, so as to control the gate driver to sequentially charge the corresponding pixel row in the pixel array through the corresponding gate line, so that the source The video data output by the electrode driver is transmitted to the correspond...
