Abstract

The invention provides a drive method and device for a display panel and a display device. The drive method for the display panel is applied to the display panel; a data drive circuit and a plurality of data lines are arranged on the display panel. The drive method for the display panel comprises the following steps: in a display time quantum of each frame, setting a corresponding slew rate for each data line according to routing resistance, inside the display panel, of the corresponding data line, wherein the slew rates set for the data lines, with the distance from near to far to the data drive circuit on the display panel, are gradually increased; and in the display time quantum of each frame, loading data voltage signals with the corresponding slew rates by the data drive circuit for the data lines. The drive method and device provided by the invention solves the problem that brightness loss cannot avoided while display brightness unevenness is improved in the prior art.

Description

technical field [0001] The present invention relates to the technical field of display driving, in particular to a driving method, device and display device of a display panel. Background technique [0002] In the prior art, the data drive circuit (Source Driver IC) that applies data voltage to the multiple data lines included in the liquid crystal display module is arranged in the middle of the display substrate, and the data lines are arranged on the display substrate from left to right. Arranged in sequence (for example, data is 1-960, the middle data line is 480, the leftmost data line is 1, and the rightmost data line is 960), so the Fan out resistance of the data line in the middle of the display substrate (Fan The out resistance is the wiring resistance of the data line inside the display panel) is the smallest, and the Fan out resistance of the data line on both sides of the display substrate is relatively large. Different Fanout resistances cause the data voltage to...
