OG exemplary drawing
 
1. A display panel, for displaying images comprising a first frame and a second frame, the display panel comprising:
a plurality of subpixels;
a plurality of scan lines, arranged in a first direction and connected to the plurality of sub-pixels;
a plurality of data lines, arranged in a second direction crossing the first direction, and connected to a plurality of the sub-pixels, wherein a polarity of a first data voltage input to the subpixels in a display period of the first frame is opposite to a polarity of a second data voltage input to the subpixel in a display period of the second frame;
a compensation module, electrically connected to the plurality of data lines, and 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 subpixel in a blank period of the second frame, wherein a polarity of the first compensation voltage is the same as the polarity of the first data voltage, and a polarity of the second compensation voltage is the same as the polarity of the second data voltage;
wherein the first compensation voltage is not zero, and the second compensation voltage is not zero;
wherein the compensation module comprises a compensation voltage output terminal electrically connected to the plurality of data lines, and configured to output the first compensation voltage and the second compensation voltage, and wherein an absolute value of the first compensation voltage is less than an absolute value of the first data voltage, and an absolute value of the second compensation voltage is greater than an absolute value of the second data voltage.
