1. A method of processing an image signal of a liquid crystal display, comprising:
receiving a previous image signal and a current image signal as two sequential input image signals; performing 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 for the current image signal; and post-processing the correction image signal corresponding to a portion of the plurality of doubled frames to generate a final correction image signal, wherein the generating of the final correction image signal comprises outputting the current image signal before the first correction as the final correction image signal, or multiplying the correction image signal corresponding to the portion of the plurality of doubled frames by a weight value and outputting the multiplied result as the final correction image signal, wherein the generating of the correction image signal comprises doubling the current image signal or the correction image signal into the plurality of doubled frames according to a temporal gamma mixing (TGM) mode, wherein the TGM mode applied to the plurality of doubled frames for two sequential input images includes one of an HL-LH mode and an LH-HL mode.
