Patent attributes
An organic EL drive circuit includes a reset voltage generator circuit for generating a predetermined constant voltage for constant voltage resetting, reset switches provided between an output of the reset voltage generator circuit and terminal pins of an organic EL display panel and ON/OFF controlled by one of the timing control signal, a reset control signal similar to the timing control signal, a reset pulse, other pulse generated in the reset period in synchronism with these signal, and the pulse and an output terminal for outputting the predetermined constant voltage to other organic EL drive circuits, which have identical circuit constructions to that of the organic EL drive circuit and arranged adjacently to the organic EL drive circuit, as a voltage for constant voltage resetting.
