ABSTRACT:
A display device comprising a display panel having pixels arrayed at intersections of mutually orthogonal gate lines and data lines, and a driving circuit for sampling a plurality of video signals simultaneously and distributing the sampled signals concurrently to a predetermined number of data lines; a video driver for relatively delaying the video signals in accordance with the array pitch of the pixels and adjusting the supply timing of the video signals to the display panel; and a timing generator for controlling the simultaneous sampling period of a driving circuit included in the display panel and also controlling the timing of the delay process executed by the video driver. The timing generator is capable of selectively switching the simultaneous sampling period and controlling the delay process timing of the video driver in response to such selective switching to thereby optimize, with respect to the simultaneous sampling period, the supply timing of the input video signals to the display panel. This display device is adapted to prevent occurrence of a vertical streak ghost in a simultaneous multiple-pixel sampling mode.
