Abstract
A display panel, for displaying images including a first frame and a second frame, includes subpixels, scan lines, data lines, and a compensation module. The data lines are configured to input a first data voltage to the subpixels in a display period of the first frame and to input a second data voltage to the subpixels in a display period of the second frame. The compensation module is configured to input a first compensation voltage to the subpixels in a blank period of the first frame and to input a second compensation voltage to the subpixels in a blank period of the second frame, where the first compensation voltage is not zero, and the second compensation voltage is not zero.
