Abstract

The present invention belongs to the technical field of display, and mainly provides a method and a device for driving of a display panel. The method comprises the steps of: outputting initial scanning signals comprising two pulse signals, when a first pulse signal is received at a pixel drive unit at an xth line, performing pre-charging of the pixel drive unit at the xth line, when a second pulse signal is received at the pixel drive unit at the xth line, performing charging of the pixel drive unit at an xth line, performing data writing-in for the pixel drive unit at an xth line, and performing pre-charging of a pixel drive unit at an (x+4m)th line. Therefore, the charging time of the pixel drive units in the display panel is improved, and the problem is solved that a current GOA drivecircuit has an undercharge problem to possibly cause the abnormal display of the display panel.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a method and device for driving a display panel. Background technique [0002] The liquid crystal panel includes pixel units in rows and columns. When the liquid crystal panel is working, the gate drive signal controls the opening and closing of the thin film transistor (Thin Film Transistor, TFT) in the pixel unit, thereby completing the row scanning of the liquid crystal panel and realizing the liquid crystal display. The function of displaying images on the panel. Therefore, the liquid crystal panel is an important part of the display device. With the development of display panel technology, the resolution of the display panel is gradually increasing. The number of gate ICs required by the display panel It is also gradually increasing. In order to reduce the cost, the gate drive circuit substrate (Gate on Array, GOA) technology integrates the function of the gate IC on the...
