El display and driving circuit for the same |
摘要 |
The present EL display includes a step-up circuit for increasing a voltage of a DC power supply in response to a pulse signal output by an oscillator, a switching circuit connected with the step-up circuit and including first through fourth MOSFETs and an inverter, an EL element connected with an output terminal of the switching circuit, and a voltage detector for outputting a control signal in response to an output signal from the switching circuit for instructing a switching operation of the switching circuit. The step-up circuit includes a series circuit of a coil and a diode serially connected with each other and a step-up transistor connected with a node in the series circuit at its main electrode for receiving the pulse signal at its control electrode.
