LIQUID CRYSTAL DISPLAY, METHOD FOR DRIVING THE SAME, AND PICTURE DISPLAY APPLICATION DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display with which a high definition and high quality display picture can be obtained by making picture data during power-off always constant and moreover by making them white picture data in which an after image can not be recognized, and to provide its driving method.;SOLUTION: A power source-off circuit 4 in which synchronizing signals H, V, D are inputted and also an off signal which is inputted just before the power source is turned off is provided to a liquid crystal display device. This power source-off circuit 4 is constituted so as to output synchronizing signals HS, VS, DE which become signals identical to the synchronizing signals H, V, D before the off signal is inputted to the circuit and become fixed signals after the off signal is inputted to the circuit. An LCD (liquid crystal display) controller 7 inputs the synchronizing signals HS, VS, DE coming from the power source-off circuit 4 and makes an LCD panel 8 perform white display by discriminating that the synchronizing signals HS, VS, DE are fixed forcibly on the basis of the off signal.;COPYRIGHT: (C)2003,JPO
