Display device and method for driving display panel

A display device comprising:

• a display panel comprising a plurality of sub-pixels and a plurality of data lines, wherein each of the plurality of sub-pixel is connected to one of the data lines;
• and
• a circuit, configured to obtain an image having a plurality of gray levels corresponding to the sub-pixels respectively,
• wherein for a first sub-pixel of the sub-pixels, the circuit is configured to obtain a second sub-pixel correspondingly,
• wherein the circuit is configured to calculate a first compensation value according to the gray level corresponding to the first sub-pixel and the gray level corresponding to the second sub-pixel,
• wherein the circuit is configured to calculate a second compensation value according to a polarization state of the first sub-pixel, a polarization state of the second sub-pixel, and a difference between the gray level corresponding to the first sub-pixel and the gray level corresponding to the second sub-pixel,
• wherein the circuit is configured to calculate a gain according to a position of the first sub-pixel,
• wherein the circuit is configured to compensate the gray level corresponding to the first sub-pixel according to the first compensation value, the second compensation value, and the gain to obtain an output gray level, and drive the first sub-pixel according to the output gray level.
