Abstract

The embodiment of the invention provides an array substrate, a driving method thereof and a display device, relates to the technical field of display and is used for avoiding that a TFT (thin film transistor) is in a one-way bias state for a long time. The array substrate comprises multiple pixel groups in matrix arrangement, each pixel group comprises a first pixel unit and a second pixel unit. The first pixel unit comprises a first switch module connected with the pixel electrode of the first pixel unit. In a closed phase of the first switch module, the signals output by a first grid line and a common grid line are different, and the signals output, in a first subphase and a second subphase, by the first grid line and the common grid line are opposite. The second pixel unit comprises a second switch module connected with the pixel electrode of the second pixel unit. In a closed phase of the second switch module, the signals output by a second grid line and the common grid line are different, and the signals output, in a third subphase and a fourth subphase, by the second grid line and the common grid line are opposite.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate, a driving method thereof, and a display device. Background technique [0002] LCD (full name in English: Liquid Crystal Display, full name in Chinese: liquid crystal display), as a flat panel display device, is more and more popular because of its small size, low power consumption, no radiation and relatively low production cost. It is used in the field of high-performance display. [0003] The LCD includes an array substrate and a cell-to-cell substrate that are aligned with each other. Among them, on the array substrate such as Figure 1a As shown, there are gate lines Gate and data lines Data that intersect horizontally and vertically. Among them, a TFT (full name in English: Thin Film Transistor, full name in Chinese: thin film transistor) is disposed at the intersection of the gate line Gate and the data line Data. When a row of gate line...
