The invention discloses an array substrate, a driving method thereof and a display device. A control switch transistor electrically connected with two pixel units is arranged between the two pixel units with opposite voltage polarities stored in each row of pixel units. Before each row of pixel units are charged, under the control of a first control signal, a control switch transistor of the corresponding row is turned on, so that the stored two pixel units with opposite voltage polarities are subjected to electric quantity neutralization. Within scanning time, under the control of a second control signal; a switching transistor is controlled to turn off. so that he two stored pixel units with opposite voltage polarities are disconnected; when the pixel units are charged, the pixel unitsare charged. Compared with a mode of charging from positive polarity voltage to negative polarity voltage or charging from negative polarity voltage to positive polarity voltage, the charging charge quantity is reduced, so that the charging time is shortened, the refresh rate is improved, the charging heat productivity is reduced, the burden of a chip is reduced, and the power consumption is 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] Thin Film Transistor (Thin Film Transistor, TFT) Liquid Crystal Display (Liquid Crystal Display, LCD) has attracted the attention of the industry due to its excellent performance, good mass production characteristics, and broad development space. [0003] During the working process of TFT LCD, in order to avoid permanent damage caused by polarization of the liquid crystal material, it is usually necessary to reverse the polarity of the voltage signal applied to both ends of the liquid crystal capacitor and the storage capacitor every predetermined time, so it is necessary The polarity inversion driving is performed on the pixel units on the array substrate. Common polarity inversions include: frame inversion, column inversion, row inversion, and dot inversion, etc. [0004]...
