Abstract

An electroluminescent display and a method of driving the same are disclosed. The electroluminescent display includes a driving transistor (DT) configured to generate a driving current depending on a gate-source voltage, a storage capacitor (Cst) configured to store a data voltage (Vdata) and provide the stored data voltage (Vdata) to a gate electrode of the driving transistor (DT), a first switching transistor (ST1) configured to control a gate potential of the driving transistor (DT), a second switching transistor (ST2) configured to control a source potential of the driving transistor (DT), a light emitting diode (OLED) configured to emit light in response to the driving current generated from the driving transistor (DT), and a third switching transistor (ST3) configured to electrically float a source electrode of the driving transistor (DT) and an anode electrode of the light emitting diode (OLED) when one of the first and second switching transistors (ST1, ST2) is turned off.
