Abstract

Electroluminescent display panel and method for operating the same. The electroluminescent display panel having a plurality of unit pixels defined by a plurality of gatelines, and a plurality of sourcelines running perpendicular to each other, the unit pixel including a first switching device, a capacitor having a first terminal connected to an output terminal of the first switching device, and a second terminal connected to a power source voltage terminal, a second switching device connected to the power source voltage terminal, an electroluminescent part, and a light emission suppressing part connected to the one end of the capacitor for turning off the electroluminescent part for a preset period during a period before the present frame is operated, by receiving an enable signal that causes discharge of the capacitor and discharging a charge stored in the capacitor, thereby fabricating a high definition display.
