Patent ID: 8405650

Claim:
A method for driving a display device including a plurality of pixels arranged in a matrix form, a plurality of source signal lines inputting a video signal to the plurality of pixels, and a source driver outputting signals to each of the plurality of source signal lines, wherein the source driver includes a shift register and an image signal input line to which a video signal is input, the method comprising: determining whether or not video signals corresponding to all of pixels in one row of the plurality of pixels are equal to one another; in a case where video signals corresponding to at least two pixels of the video signals corresponding to the pixels in one row of the plurality of pixels are different from each other, sequentially outputting video signals input to the image signal input line to the plurality of source signal lines in synchronization with a sampling pulse output from the shift register; and in a case where the video signals corresponding to all of the pixels in one row of the plurality of pixels are equal to one another, stopping input of a start pulse to the shift register and simultaneously outputting the video signals input to the image signal input line to all of the plurality of source signal lines.
