Abstract
A method for driving a thin-film electroluminescent (EL) display panel comprises the steps of charging the EL display panel by applying to the EL display panel a voltage of KV.sub.0 where V.sub.0 is a voltage for emitting electroluminescence from the EL display panel and K is more than zero and less than 1, and applying the voltage of V.sub.0 to the EL display panel, whereby the EL display panel is driven with a stepwise driving pulse due to the capacitance feature of the EL display panel. A circuit for enabling the method is also provided.
