US 12,118,917 B2 · Driving system and driving method of display panel

Abstract

A driving system and a display panel are provided. The driving system includes a timing controller and a driving chip. The driving chip receives the video signal and processes the video signal to output a characteristic current or a regular current to the display panel. The driving chip outputs the characteristic current to the display panel when the driving chip receives the characteristic video signal and to output the regular current to the display panel when the driving chip receives the regular video signal, and the characteristic current is smaller than regular current. The driving system of the display panel according to the present disclosure could alleviate the capacitor coupling effect caused by the large voltage jump introduced by the huge gray value difference when the display panel in a frame transition and thus improve the horizontal crosstalk of the display panel.
