Abstract
A display devices with better visual effects and low power consumption in inversion manners is provided. The display device includes a display panel and a driving circuit. The display panel includes scan lines, pixels, first common electrodes and second common electrodes. The second common electrodes and the first common electrodes are alternately arranged. The driving circuit provides a first common voltage to the first common electrodes and provides a second common voltage to the second common electrodes in a first time interval of a first frame time interval and a second time interval of a second frame time interval. In addition, the driving circuit provides the second common voltage to the first common electrodes, and provides the first common voltage to the second common electrodes in the first time interval of the second frame time interval and the second time interval of the first frame time interval.
