The invention discloses an array substrate, a display device and a charging control method, and belongs to the field of liquid crystal displays. The array substrate comprises pixel units arranged according to a matrix, multiple sets of control switches and multiple control lines; each set of the control switches comprise multiple control switches and are connected with the two adjacent rows of pixel units, each control switch in each set of the control switches is connected with two pixel units located in the two adjacent rows of pixel units respectively, the voltage polarities stored in the two pixel units which are connected with the corresponding control switch are opposite, and each pixel unit is only connected with one control switch; the control lines are used for controlling switch-on or switch-off of the control switches under the action of a control signal, and the control signal is used for controlling switch-off of the control switches connected with the two adjacent rows of the pixel units in each frame within the set time period before the grid lines of the two adjacent rows of pixel units which are connected with each set of the control switches are opened.
Description
Technical field [0001] The invention relates to the field of liquid crystal displays (English Liquid Crystal Display, LCD for short), and in particular to an array substrate, a display device and a charging control method. Background technique [0002] Thin Film Transistor (English Thin Film Transistor, TFT for short) LCD has become a mainstream product in the current display field due to its excellent performance, good mass production characteristics, and broad development space. [0003] During the working process of TFT LCD, in order to prevent the polarization of the liquid crystal material from causing permanent damage, it is usually necessary to reverse the polarity of the voltage signal applied to the liquid crystal capacitor and the storage capacitor every predetermined time. The pixel unit on the array substrate is driven by polarity inversion. Common polarity inversions include: frame inversion, column inversion, row inversion and dot inversion. [0004] The following tak...
