Patent ID: 7071930

Claim:
An active matrix display device comprising: a panel on which pixels are arranged in a matrix pattern; a scanning circuit for sequentially selecting pixels on the panel in units of rows; and a signal circuit which sequentially receives pieces of video data, each including a status part indicating need/no need for rewriting a pixel and a main data part including video data to be written into the pixel, and which writes corresponding video data into pixels which have been determined to be rewritten based on the status part among the selected pixels, while skipping the other pixels, wherein the signal circuit receives a video signal including dot data and skip data, both data having the same format including a status part and a data part, the signal circuit determines whether the video signal includes the dot data or the skip data, and when it is determined that the video signal includes the skip data, the signal circuit obtains a skip amount indicating the number of pixels to be skipped from the data part of the skip data, and when it is determined that the video signal includes the dot data, the signal circuit extracts luminance information of a pixel to be rewritten from the data part of the dot data.
