Abstract

The invention provides an array substrate, a display device and a driving method of the display device, and relates to the technical field of display. The voltage of a pixel can be charged to be saturated faster, and then the Mura problem of the display device is relieved. The array substrate comprises a plurality of grid lines and a plurality of data lines, and the data lines extend to a non-display region from a display region; in the display region, the grid lines and the data lines intersect to define sub-pixels; the non-display region comprises a switching module. The switching module is connected with the grid lines and control lines and used for being controlled by the control lines to be started, the grid lines are electrically connected, and the grid lines have start signals, so that reference voltage input by the data lines when the array substrate works is output to the sub-pixels. The reference voltage is between a positive polarity data voltage value and a negative polarity data voltage value input by the data line on adjacent frames.

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 thereof. Background technique [0002] A Liquid Crystal Display (LCD for short) has the advantages of small size, low power consumption, and no radiation, and occupies a dominant position in the display field. [0003] In LCD, pixel charging is an important factor affecting its display. In actual display, in order to ensure the display effect, the voltage of all pixels is required to reach a predetermined voltage, and when the gate voltage fluctuates, the pixel voltage will not fluctuate accordingly, that is, the pixel voltage is charged to a saturated state during display. If the charging rate of a certain pixel is low, the brightness of the corresponding position of the pixel on the display screen will be low, which will lead to serious problems such as display screen Mura (a phenomenon of poor picture quality)...
