Electroluminescent display panel and method for operating the same

A method for operating an electroluminescent display panel having a plurality of unit pixels, gatelines and sourcelines, both arranged to cross each other, a first switching device for switching a data signal in response to a signal provided to the gateline, a capacitor for having a data voltage provided through the first switching device and charged thereto, a second switching device connected to a power source voltage terminal for being switched by a voltage induced at the capacitor, an electroluminescent part for emitting a light by a power source voltage provided through the second switching device, the method comprising:

• applying a data voltage to the sourceline, dividing each frame into a normal period and a black period, and applying a real data in the normal period and applying a black data voltage in the black data period;
• enabling gatelines of the plurality of unit pixels progressively in the normal period and the black data period;
• and
• in the enabling of the gatelines, applying the black data voltage to the gatelines in the black data period, for displaying a picture while turning off the electroluminescent part repeatedly at fixed intervals.
