ABSTRACT:
A driver circuit for a display device, in which first and second clock pulse generator circuits generate first and second clock pulses to a gate circuit for allowing the first clock pulse to pass when the first and second clock pulses are a high level, and by the output of the gate circuit, a combination of a transistor and an inductance generate a high voltage pulse. The high voltage pulse is rectified in a triple voltage rectifying circuit to output a high voltage output for driving the display device such as EL elements, and the high voltage output can be reset by a low frequency pulse output from a discharge circuit. As a result, no inverter is required, and a small-sized and light-weighted driver circuit is achieved with a long luminescence life of the EL elements and without noises offensive to the ear.
