Liquid crystal display device and method for driving the same with driving of both ends of display electrodes

摘要

The invention is intended to eliminate display unevenness caused by lateral luminance error or longitudinal luminance error or crosstalk in image display on liquid crystal panel by using a low-cost drive circuit, relating to a liquid crystal panel 14 having 2N scanning lines 12 arranged in the horizontal direction, and M signal lines 10, 11 disposed in the vertical direction, in which the scanning lines 12 are driven simultaneously at both ends by using scanning line left drive circuit 17A and scanning line right drive circuit 17B. Drive pulses are sequentially applied to the scanning lines 12 at addresses X1 to X2N to turn on the individual scanning lines 12. Necessary voltage pulses are simultaneously applied to the signal lines 10, 11 at addresses Y1 to YM to control each pixel. As compared with the conventional method of one-end driving, the luminance error is reduced to 1/4, and it is effective for enhancing the picture quality, especially in large-sized liquid crystal panel. <IMAGE>
