Display device and processing method of image signal thereof

A liquid crystal display comprising:

• an image signal processor configured to receive a previous image signal and a current image signal as two sequential input image signals, and perform a first correction dynamic capacitance compensation (DCC) and a doubling for the current image signal to generate a correction image signal comprising a plurality of doubled frames that are doubled for the current image signal,
• wherein the image signal processor comprises a post processor configured to post-process the portion of the plurality of doubled frames to generate a final correction image signal.

A method of processing an image signal of a liquid crystal display, comprising:

• performing a dynamic capacitance compensation (DCC) and a doubling based on a current image signal to generate a correction image signal comprising a plurality of doubled frames;
• and
• post-processing a portion of the plurality of doubled frames to generate a final correction image signal.
