Abstract

The invention provides a polarity inversion driving method, a polarity inversion driving device and a display device. By means of the polarity inversion driving method, the polarity inversion driving device and the display device, driving voltage provided by a driving circuit can be reduced, and power consumption is reduced. The polarity inversion driving method comprises the steps that in a previous display cycle, first common voltage is provided for a common electrode of a pixel unit, and first gray scale voltage is provided for a pixel electrode of the pixel unit; in a next display cycle, second common voltage is provided for the common electrode of the pixel unit, and second gray scale voltage is provided for the pixel electrode of the pixel unit. The polarity of the first gray scale voltage relative to the first common voltage is opposite to the polarity of the second gray scale voltage relative to the second common voltage, and the first common voltage is different from the second common voltage.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a polarity inversion driving method, a polarity inversion driving device and a display device including the polarity inversion driving device. Background technique [0002] Liquid crystal display devices are widely used in electronic display devices such as mobile phones, televisions, and notebook computers due to their low radiation and thin thickness. A pixel unit of a liquid crystal display device includes a thin film transistor, a pixel electrode and a common electrode. The gate of the thin film transistor is electrically connected to the scanning line, the source is electrically connected to the data line, and the drain is electrically connected to the pixel electrode. When the scanning signal is applied to the scanning line, the thin film transistor is turned on, and the data signal output by the data driving circuit is applied to the pixel electrode...
