Abstract:
A control signal for removal of an afterimage from an active matrix display device is generated after the removal or disconnect of power from the device. A detector circuit receives a first voltage from a first voltage source and a second voltage from a second voltage source, and outputs a detection signal when either one of the first and second voltages drops to a given voltage level. An output circuit which receives the detection signal and outputs the control signal for removal of the afterimage from the active matrix display device.
