ABSTRACT:
A liquid crystal display device includes liquid crystal pixels arrayed substantially in a matrix, a vertical driving circuit that selects the rows of pixels for video signal writing and for non-video signal writing, a horizontal driving circuit that writes a video signal in the pixels of a row selected for the video signal writing and a non-video signal in the pixels of a row selected for the non-video signal writing, and a control circuit that controls operation timings of the horizontal driving circuit and vertical driving circuit. In particular, the vertical driving circuit is configured to set a selection pattern for disabling an overlap between a selection period of selecting the pixels of each row for the video signal writing and a selection period of selecting the pixels of another row for the non-video signal writing, based on enable signals from the control circuit.
