Abstract
An electroluminescent display and a method of driving the same are disclosed. The electroluminescent display includes a driving transistor configured to generate a driving current depending on a gate-source voltage, a storage capacitor configured to store a data voltage and provide the stored data voltage to a gate electrode of the driving transistor, a first switching transistor configured to control a gate potential of the driving transistor, a second switching transistor configured to control a source potential of the driving transistor, a light emitting diode configured to emit light in response to the driving current generated from the driving transistor, and a third switching transistor configured to electrically float a source electrode of the driving transistor and an anode electrode of the light emitting diode when one of the first and second switching transistors is turned off.
