Patent ID: 8102339

Claim:
A drive circuit for a display device including a plurality of video signal lines for transmitting an externally inputted video signal representing an image to be displayed, a plurality of scanning signal lines crossing the plurality of video signal lines, a plurality of switching elements arranged in a matrix form at their corresponding intersections between the plurality of video signal lines and the plurality of scanning signal lines, a plurality of pixel electrodes connected to their respective switching elements, and a display section for displaying the image, including the plurality of video signal lines, the plurality of scanning signal lines, the plurality of switching elements, the plurality of pixel electrodes, and a common electrode, the drive circuit comprising: a scanning signal line drive circuit for selectively driving each of the plurality of scanning signal lines for a predetermined period; and a video signal line drive circuit for sequentially applying a voltage to the plurality of video signal lines as the video signal, while reversing a polarity of the video signal every the predetermined period, wherein the video signal line drive circuit reverses an order of applying the video signal to the plurality of video signal lines every the predetermined period, wherein the common electrode is commonly provided for the plurality of pixel electrodes so as to form predetermined capacitances with the plurality of pixel electrodes, the common electrode being alternately switched between a high potential voltage level and a low potential voltage level every the predetermined period, wherein the video signal line drive circuit includes a shift register for shifting timing data that is externally inputted in order to generate a plurality of sampling pulses used for sequentially applying the video signal to the plurality of video signal lines, wherein the shift register shifts the timing data in a reverse direction every the predetermined period, and wherein the video signal is sequentially applied to the video signal lines in accordance with the plurality of sampling pulses generated in accordance with a direction in which to shift the timing data.
