发明名称 LIQUID CRYSTAL DISPLAY DEVICE AND ITS DRIVING METHOD
摘要 <p>PURPOSE:To realize the large-area active matrix display device by eliminating the deficient writing of liquid crystal due to the delay of a scanning line signal. CONSTITUTION:The active matrix type liquid crystal display device is constituted by providing plural scanning lines 101 and picture element electrode arrays on a 1st substrate, providing nonlinear elements between the scanning lines and picture element electrodes, and charging liquid crystal in the gap between the 1st and 2nd substrates. A photoconductive film 104 is sandwiched between the picture element electrodes and scanning lines, photoconductive layers 102 and 102' are provided nearby the photoconductive film 104, and light beams LZ1 and LZ2 are propagated to the photoconductive films 102 and 102' to irradiate the photoconductive film 104 from the photoconductive layers 012 and 102'; and thus the resistance of the photoconductive film 104 is varied and this variation is utilized to apply a voltage to the picture element electrodes, thereby writing data in picture elements. Consequently, rate determination based upon the delay of the scanning lines of a conventional active matrix type liquid crystal display device is eliminated and the writing to the liquid crystal is performed at a high speed.</p>
