Patent ID: 6841948

Claim:
A device for driving a luminescent display panel comprising; a luminescent element, a drive TFT for light-up driving the luminescent element, a control TFT for controlling the gate voltage of the drive TFT, and a power source circuit that, for causing the luminescent element to perform its luminescing operation, can supply a forward-directional electric current to the luminescent element and apply a reverse bias voltage that is reverse to the forward-directional current voltage to the luminescent element, wherein the power source circuit is the one that outputs a power source voltage level the potential of that is positive or negative with respect to the reference potential, and the power source circuit is arranged so that, in a state of supplying a forward-directional electric current to the luminescent element, it supplies a power source voltage level of positive potential to one terminal functioning as the anode of the luminescent element and supply a power source voltage level of negative potential to the other terminal functioning as the cathode of the luminescent element; and so that, in a state of applying a reverse bias voltage to the luminescent element, it supplies a power source voltage level of negative potential to the one terminal functioning as the anode of the luminescent element and supply a power source voltage level of positive potential to the other terminal functioning as the cathode of the luminescent element; and at least the drive TFT and control TFT are each constructed using the same channel TFT.
