Abstract
A liquid crystal display device is provided. An image memory ( ) stores therein input pixel data (R , B , G ) on a frame-by-frame basis. Differencing circuits ( to ) calculate respective difference data ((R −G ), (B −R ), (G −B )) on a pixel-by-pixel basis. Comparator circuits ( ) output a pulse when the difference data is greater than a difference level (DLV). Counter memories ( to ) perform a counting operation each time the pulse is inputted thereto, and output respective counts (FLN_R, FLN_B, FLN_G) after the counting operation for one line. Comparator circuits ( to ) output a pulse to skip flag registers ( to ), respectively, when the respective counts are greater than a skip level. Skip flags (SPF_Ri, SPF_Bi, SPF_Gi) corresponding to a current line are set at “1.” A gate pulse for the line corresponding to the skip flags “1” is skipped. This reduces the write time of image data.
