摘要： First to N-th latches capture N pieces of pixel data indicative of the luminance levels of respective pixels in synchronization with first to N-th capture clock signals each having different edge timing. Voltages corresponding to the pieces of pixel data output from the first to N-th latches are applied to each of the data lines of the display device. In this case, first to N-th flip-flops formed in an N-stage shift register capture a single pulse load signal which is synchronized with a horizontal synchronizing signal in a video signal while sequentially shifting the load signal to subsequent stages in synchronization with a reference timing signal supplied from the outside. Outputs of the first to N-th flip-flops in the N-stage shift register are supplied as first to N-th capture clock signals, to the first to N-th latches, respectively.
