Abstract:
An EL display comprising:step-up signal generating means for generating a step-up signal by increasing a supply voltage in accordance with a pulse signal;switching circuit for outputting a first output signal in response to said step-up signal and for outputting a second output signal by inverting a polarity of said step-up signal;an EL element including electrodes connected with a first output terminal and a second output terminal of said switching circuit, respectively; anda voltage detector for inverting a polarity of said second output signal of said switching circuit by receiving said first output signal from said switching circuit and outputting a control signal to said switching circuit on the basis of a predetermined voltage of said received first output signal,wherein a voltage applied across said EL element is formed by a potential difference between output signals outputted from said first output terminal and said second output terminal, respectively.
