Patent ID: 6894669

Claim:
A display control device of a liquid crystal panel, comprising: a data memory unit for storing image data to be supplied correspondingly to each single frame period for which a single frame of the liquid crystal panel is displayed; a data comparison unit for determining, on each pixel of said liquid crystal panel, a difference between image data supplied anew and image data of a frame immediately preceding and stored in said data memory unit; an operational unit for determining, for subfield(s) of a plurality of subfields other than a last subfield, based on said difference, exceeded display data for setting the transmittance of said each pixel to a value greater than a target transmittance corresponding to image data supplied anew, the plurality of subfields constituting said single frame period, and for determining, for said last subfield of said single frame period, based on said difference, target display data for setting the transmittance of said each pixel to said target transmittance; and a timing control unit for generating timing signals synchronizing with each of said plurality of subfields, receiving said exceeded display data and said target display data in succession from said operational unit, and outputting, in synchronization with said timing signals, driving signals of said liquid crystal panel according to the received display data.
