<p><P>PROBLEM TO BE SOLVED: To prevent display luminance difference and burning with a line at which an order of inversion of black and video changes in the middle of the screen by a frame insertion drive and the polarity inversion generated by variation of field through in a panel surface and variation in positive and negative of the application voltage switches as a boundary. <P>SOLUTION: An enable signal (VOE) to each of gate drivers 5A-5N is independently controlled, a start pulse (VSP) input to write a black signal is performed at an arbitrary timing with one frame period with respect to the gate driver 5A to insert the black image within one frame period, a write polarity of the video signal is inverted in frame cycle with the video display start pulse as a base point, and a write polarity of a black image signal is inverted in frame cycle with the black display start pulse as a base point. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
