ABSTRACT:
An active matrix display device includes a pixel array unit having pixels arranged in a matrix pattern, a scanning circuit which sequentially selects pixels in unit of rows, and a signal circuit which receives a video signal containing serial dot data corresponding to each pixel and which writes the dot data into a selected pixel. The signal circuit receives a video signal which includes dot data corresponding to pixels to be rewritten but does not include dot data corresponding to pixels not to be rewritten and which includes skip data defining a skip amount. The signal circuit sequentially processes the dot data and skip data so as to write the corresponding dot data into pixels to be rewritten by skipping pixels not to be rewritten based on the skip data.
