发明名称 LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a display device whose operating life of a liquid crystal panel is extended by alleviating an image persistence phenomenon caused by absorption of ions, produced by photo- or thermal-decomposition of an organic material due to long time irradiation of intense light on the liquid crystal panel, to an alignment layer and/or an electrode interface, and a method for driving the same. <P>SOLUTION: The ions giving rise to the image persistence phenomenon are made to be dissociated from the alignment layer 22A, 22B and/or the electrode interface by reducing at least an electric potential, preferably both electric potentials of a pixel electrode 21B and a counter electrode 21A of a liquid crystal cell in the pixel to the ground level in a time period other than an operating time to carry out a picture display, especially in a stand-by mode state aiming at power saving. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p>
