Abstract

The invention provides a driving system of a display panel and a driving method of the display panel. The driving system of the display panel comprises a time schedule controller and a driving chip. When the driving chip receives the characteristic video signal, characteristic current is output to the display panel, when the driving chip receives the conventional video signal, conventional current is output to the display panel, and the characteristic current is smaller than the conventional current. The driving system of the display panel is provided with two groups of different driving currents, so that the capacitive coupling effect of common electrodes caused by overlarge voltage jump when the gray scale difference value of picture switching is overlarge is avoided, and the horizontal crosstalk phenomenon of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel drive system and a display panel drive method. Background technique [0002] With the development of liquid crystal display technology, the requirements for Thin Film Transistor Liquid Crystal Display (TFT-LCD) in terms of high resolution, wide viewing angle, high response speed, and high aperture ratio are getting higher and higher. At the same time, with the shrinking of the pixel size, the line spacing on the TFT substrate is getting smaller and smaller, and the coupling between different signal lines is intensified. When a signal jumps, it may affect the stability of other surrounding signals. . [0003] During the research and practice of the prior art, the inventors of the present application found that when the gray scale difference of the screen before and after the display panel switching is large, the data voltage needs to jump when switc...
