A liquid crystal display driven by a dot-line inversion driving method in combination with a 2-step dot sequential precharge driving method which, if black window or black lines are displayed, is free of horizontal trails on circumscribing portions thereof is provided. Before video signals having opposite polarities are applied to signal lines, first, a full-line precharge pulse is generated in the horizontal blanking periods, and precharge gray signals which have the same polarity as that of the previous pixel potential are written together based on the full-line precharge pulse. Then, precharge black signals having the same polarity as that of one of the video signals, and precharge gray signals having the same polarity of that of the other video signal are written in two steps.
A display device comprising:
A method of driving a display device, for writing video signals having polarities opposite to each other to two odd-numbered rows of pixels which are spaced apart in adjacent pixel columns so that the polarities of the horizontally adjacent pixels are the same while the polarities of the vertically adjacent pixels are opposite in the array of pixels to which the video signals have been written, said method comprising the steps of:
