Abstract

The application provides an array substrate and production method thereof, a driving method, a display panel and a display device in order to reduce displaying power consumption; two thin-film transistors are arranged on a pixel unit to control charging for pixel electrodes and common electrodes, so that separate voltage adjustment is achieved for the pixel electrodes and the common electrodes; when a voltage difference between the pixel electrodes and the common electrodes is about to reach -4 to +4 V, their voltage adjusting ranges can be -2 to 2 V, namely driving voltage ranges of first andsecond signal lines can be -2 to 2 V. Compared with the prior art where driving voltage of data lines is 0-5 V, the array substrate and the production method thereof, the driving method, the displaypanel and the display device have the advantages that driving voltages on the first and second signal lines are greatly decreased and displaying energy consumption is further reduced.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to an array substrate, a manufacturing method thereof, a driving method, a display panel and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor-Liquid Crystal Display) is still the mainstream display product at present. With the popularity of smart phones and TVs, the market demand is increasing. In recent years, major panel manufacturers have been continuously devoting themselves to reducing the power consumption of TFT-LCD display products. [0003] In the process of driving and displaying the LCD, a voltage difference of 0-4V needs to be formed between the voltage of the pixel electrode and the voltage of the common electrode to drive the liquid crystal to deflect and then control the grayscale display. Taking Notebook as an example, the driving voltage input by the data line or the pixel electrode voltage Vpixel is 0~8V, and the common ...
