Abstract: A circuit driving electric luminescent panel in which the high potential contact of electric luminescent panel is connected to two parallel connected transistors of which the emitter of the first transistor is connected to a current--resisting coil and the positive pole of a diode in order to raise the voltage at the contact of the electric luminescent panel. The first transistor provides, within the time when the signal at its base is low, a negative voltage to increase the peak value-to-peak value voltage across the electric luminescent panel and its luminosity as well. Furthermore, another kind of design concept is presented with which the timing impulse of controlling signals while operation can be governed with its duty to control current consumption.
