Driving method, array substrate, display panel and display device

Abstract

An embodiment of the invention relates to the technical field of display, in particular to a driving method, an array substrate, a display panel and a display device used for improving uneven brightness at junctions of independent common electrode blocks. A gate drive unit sequentially outputs gate drive signals to gate lines according to Hs, effective level time of the gate drive signals is T, wherein (N+1)*THs>T>N*THs, T-N*THs>3delta, and delta> / =R*C. Since T-N*THs>3delta, at the end of effective level in the gate drive signals received by the other gate lines in the adjacent gate lines except for the last gate lines, the voltage difference between a pixel electrode and the common electrode block corresponding to the last gate line in the adjacent gate lines reaches the stable state; therefore, uneven brightness at the junctions of the independent common electrode blocks is improved, and further stripes are generated on a display screen.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method, an array substrate, a display panel, and a display device. Background technique [0002] As an input medium, the touch screen provides users with better convenience than the keyboard and mouse. According to different implementation principles, the touch screen can be divided into resistive type, capacitive type and so on. Capacitive touch screens are widely used at present, and there are various types of display devices equipped with capacitive touch screens, such as touch-sensitive mobile phones and tablet computers. In the prior art, capacitive touch screens can be classified into self-capacitance and mutual capacitance according to the way of detecting capacitance. Relative relationship The capacitive touch screen can be divided into three types: in-cell, on-cell and out-cell. Among them, the embedded type is an important development direction of ...

Problems solved by technology

At this time, the gate drive unit scans downwards from the first gate line to the last gate line according to the order of the spatial position of the gate lines. The voltage difference between the pixel electrode corresponding to the line and the common electrode block is different, therefore, brightness unevenness will occur at the junction of two independent common electrode blocks, resulting in stripes
