ABSTRACT:
An organic EL drive circuit comprises a timing signal generator circuit for generating a plurality of second timing control signals sequentially delayed from a first timing control signal, a reset pulse generator circuit for selecting one of the plurality of the second timing control signals according to the predetermined data and generating a reset pulse having a front edge determined according to the selected second timing control signal and a rear edge determined by the first timing control signal and a switch circuit responsive to the reset pulse for connecting the terminal pins to a predetermined bias line to reset an organic EL element of an organic EL panel connected to the terminal pins. Luminance of the organic EL panel is regulated by regulating the display period according to the predetermined data.
