Abstract

The invention relates to an array substrate, a driving method and a display device thereof. The array substrate comprises a plurality of scanning lines, a plurality of data lines, a source electrode driving circuit and a gate driving circuit, wherein a plurality of pixel units are defined by the crossing of the scanning lines and data lines; each of the pixel units comprises a plurality of serially connected thin film transistors and a pixel electrode; the grid electrodes of the serially connected thin film transistors are respectively in electric connection with different scanning lines; all the pixel electrodes are electrically connected with the data lines through the serially connected thin film transistors; a time interval for writing two adjacent data voltage signals into the pixel units includes a first time period and a second time period; in the first time period, the data voltage signal inputted by the source electrode driving circuit is written into the pixel electrodes; in the second time period, each thin film transistor is at least opened for one time and the plurality of serially connected thin film transistors cannot be simultaneously under opening state. The array substrate according to the embodiment of the invention can reduce the power consumption and can reduce the TFT characteristic drifting.

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] In recent years, liquid crystal display devices have been widely used in information terminals such as computers, smart phones, mobile phones, car navigation devices, and e-books. There are many types of liquid crystal displays, among which thin film transistor (Thin Film Transistor, TFT) liquid crystal displays are used because of their applicable temperature With the advantages of wide range, high degree of automation in manufacturing technology, easy integration, and good environmental protection characteristics, it is gradually becoming a mainstream display product. How to reduce the power consumption of thin film transistor liquid crystal display devices and improve the quality of display images has become a current research hotspot. [0003] With the development of li...

Problems solved by technology

[0004] Although the low-frequency driving technology can significantly reduce power consumption, the thin-film transistor remains in the constant-level maintenance stage for a long time during the suspension period, which will cause TFT characteristic deviation and affect the display quality of the liquid crystal display device.
