Embodiment Construction

[0033] In order to solve the problem of leakage current generated by the pixel scanning structure based on Dual Gate in the prior art, the embodiment of the present invention proposes a new array substrate structure, including: gate lines, data lines and pixel electrodes, and also includes: Pixel switches with two multi-gate structures at the intersection of each gate line and each data line. One of the pixel switches of the two multi-gate structures is a pixel switch turned on by a positive gate voltage, and the other is a pixel switch turned on by a negative gate voltage.

[0034] Such as figure 1 As shown, two pixel switches TFT1 and TFT2 with a multi-gate structure at the intersection of a gate line 2 and a data line 1 are respectively used to drive two pixel switches located on both sides of the data line 1 at the intersection and connected to the data line. a pixel electrode 10. The respective gates of the two multi-gate pixel switch TFT1 and TFT2 at the intersection o...

Abstract

The invention discloses an array substrate, a display device and a drive method thereof, relating to the technical field of display. The array substrate comprises grid lines, data lines and pixel electrodes, and also comprises two pixel switches with multi-gate structures, wherein the pixel switches are arranged on cross joints of the grid lines and the data lines, one pixel switch is opened by a positive voltage of a grid, the other one pixel switch is opened by a negative voltage of the grid, the two pixel switches with multi-grid structures on the cross joint of one grid line and one data line are used for driving two pixel electrodes arranged on two sides of the data line and connected with the data line; and all grids of the two pixel switches with multi-grid structures on the cross joint of one grid line and one data line are connected with the grid line. Because the pixel switch opened by the negative voltage of the grid and the pixel switch opened by the positive voltage of the grid are of a multi-grid structure, according to the array substrate provided by the invention, a leak current can be effectively inhibited.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display device and a driving method for the display device. Background technique [0002] Array substrates of TFT-LCD (Thin Film Field Effect Transistor-Liquid Crystal Display), OLED (Organic Light Emitting Diode) display devices, electronic paper and other display devices adopt row-column matrix driving mode, which is specifically formed by crossing N rows of gate lines and M columns of data lines The row-column matrix realizes the control of each pixel electrode in the row-column matrix. [0003] On the premise that the resolution remains unchanged, in order to reduce the cost of the product, it may be considered to reduce the number of data lines. To achieve this goal, the prior art proposes a pixel scanning structure based on Dual Gate (dual gate lines), and its specific implementation is as follows: [0004] Assume that the resolution of the ...
