ABSTRACT:
An afterimage occurring on a liquid crystal display is eliminated at the time of turning off the system power with an inexpensive circuit construction, without the need for reserving a special power supply. The afterimage continues to be displayed for a certain period of time after the turning-off of the power supply, and is eliminated by the load capacitance processed by liquid crystal display elements in a liquid crystal display panel.
