Abstract: A liquid crystal display device and driving method therefor are disclosed. The device includes a plurality of signal lines that apply different gray scale voltages to each of the pixels. A driving circuit is provided to generate the gray scale voltages to be applied to the pixels. In operation, the driving circuit applies the first gray scale voltage at intervals of the horizontal scanning time within a display period. The second gray scale voltage is output by a number of times that is not smaller than twice and not greater than (M−N) times at intervals of the horizontal scanning time from the beginning of the vertical retrace interval. The second gray scale voltage is then stopped until completion of the vertical retrace interval.

Abstract: A driving method of a liquid crystal display device, even when a vertical retrace interval varies, can prevent contention between a driving signal transmitted to a driving circuit within the vertical retrace interval and a driving signal transmitted to the driving circuit within the display period of the next frame after the vertical retrace interval. The device has pixels, signal lines, and a driving circuit outputting the gray scale voltage to the signal lines. In the method, letting M be a value obtained by dividing the vertical retrace interval by a regular horizontal scanning time and rounding up a fraction after the decimal point, and letting N be an integer of 1 or more, the gray scale voltage is outputted from the driving circuit to the signal lines by a number of times between twice and (M−N) times within the vertical retrace interval.

Abstract: In a liquid crystal display panel including a plurality of scanning lines, a scanning line drive circuit which supplies a scanning voltage to the plurality of scanning lines, and a counter voltage supply circuit which supplies a counter voltage to a counter electrode of each pixel, the counter voltage supply circuit supplies a voltage which is obtained by multiplying a voltage detected from the counter electrode by correction coefficients corresponding to the plurality of respective scanning lines to the counter electrodes. The present invention provides a liquid crystal panel which can perform favorable display by preventing crosstalk attributed to coupling noises to the counter electrodes generated by AC driving of a video voltage.
