Abstract:
1. An electroluminescent display panel having a plurality of unit pixels defined by a plurality of gatelines, and a plurality of sourcelines running perpendicular to the plurality of gatelines, the unit pixel comprising: a first switching device responsive to a signal applied to a gateline for switching an analog data signal applied to a sourceline; 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, for having the analog data signal provided thereto through the first switching device and charged thereto; a second switching device connected to the power source voltage terminal for being switched by a voltage induced at the first terminal of the capacitor; an electroluminescent part for emitting a light by the power source voltage provided through the second switching device; a light emission suppressing part connected to one end of the capacitor for turning off the electroluminescent part for a preset period during a period before a present frame is operated, by receiving an enable signal that causes discharge of the capacitor and discharging a charge stored in the capacitor; and a third switching device connected between an output terminal of the second switching device and the electroluminescent part, the third switching device is driven in response to the enable signal the same as the light emission suppressing part.
