Abstract

An embodiment of the invention discloses an array substrate, a driving method thereof and a display device, and relates to the technical field of display. The array substrate comprises a plurality of pixel units in matrix arrangement, a plurality of horizontally and vertically cross grid lines and data lines are divided into the pixel units, and each pixel unit comprises pixel electrodes and common electrodes. In the pixel unit matrix, the common electrodes corresponding to the pixel units with the same sum of line number and row number are the same in voltage polarity, and the common electrodes of the adjacent pixel units are opposite in voltage polarity. By the aid of the array substrate with the structure, dot inversion is driven, and the voltage swing of data line driving voltage between a positive polarity gray level and a negative polarity gray level is greatly reduced, so that power consumption of the array substrate in a dot inversion driving mode is effectively reduced.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to an array substrate, a driving method thereof, and a display device. Background technique

[0002] Liquid Crystal Display (LCD for short) is favored by engineers because of its low power consumption, light and thin appearance, and no radiation. Therefore, it has been widely used in various electronic products including computers, mobile phones, etc. in electronic equipment. Liquid crystal displays usually include an array substrate, a color filter substrate, and a liquid crystal layer located between the array substrate and the color filter substrate. The display principle is mainly to change the liquid crystal molecules in the liquid crystal layer by changing the potential difference between the two ends of the liquid crystal layer. The rotation angle of the liquid crystal changes the light transmittance of the liquid crystal to display different images.
