Abstract: A drive device for a light-emitting display panel, having the more extended light-emitting life of an EL element, is provided. Drive switches SX1 to SXn select a reverse direction voltage ?V immediately after starting of scanning to supply the voltage ?V to all of EL elements in a scanning state. Subsequently, through the switches SX1 to SXn, constant current sources I1 to In are connected to data lines to be controlled for light emitting, and, a forward voltage +V1 (a voltage equal to or smaller than a light-emitting threshold one) is applied to data lines which do not contribute to light emitting. Thereby, the forward voltage is applied to the EL elements in a scanning state.

Abstract: A ballast for a vehicle metal halide lamp is simplified using a DC-AC one-step-boost high frequency ballast system. To satisfy requirements specific to a metal halide lamp, a discharge developing capacitor is installed on a primary side of a transformer in parallel with a DC power supply, ensuring discharge development after a breakdown. To reduce the size and increase the operating voltage of the transformer, a booster circuit and voltage-doubler circuit are installed on the primary side and secondary side of the transformer, respectively. To reduce the size of the transformer and achieve a stable discharge, the ballast frequency is swept within a range between the specified minimum frequency and maximum frequency so that the center frequency is from 80 kHz to 120 kHz, and the same frequency is unsustained for more than 10 msec.
