Abstract

The invention provides a display panel, a drive method of the display panel and a liquid crystal display device, relates to the technical field of liquid crystal displaying and aims to reduce power consumption of the display panel. The display panel comprises a source driver, a plurality of pixel units and a common voltage output driver; the pixel units are confined by a plurality of grid lines and a plurality of data lines; the common voltage output driver is used for, on an N-th frame, inputting negative common voltage to the first one of the pixel units, and, on an adjacent frame of the N-th frame, inputting positive common voltage to the first pixel unit; the source driver is used for inputting data voltage, greater than or equal to negative common voltage, to the first pixel unit when the common voltage output driver input the negative common voltage to the first pixel unit, and inputting data voltage, less than or equal to the positive common voltage, to the first pixel unit when the common voltage output driver inputs the positive common voltage to the first pixel unit.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel, a driving method thereof, and a liquid crystal display device. Background technique [0002] With the continuous development of liquid crystal display technology, the application of liquid crystal display devices is becoming more and more extensive. During the working process of the liquid crystal display device, the voltage difference between the data voltage output by the source driver and the common voltage output by the common voltage output driver, that is, the driving voltage drives the liquid crystal molecules to rotate to complete the display. In order to avoid the rotation characteristics of liquid crystal molecules being destroyed when the liquid crystal molecules are driven with a fixed driving voltage for a long time, the polarity of the driving voltage (including positive and negative polarity) usually needs to be reversed, that is, th...
