Abstract: An electroluminescent display and a method of driving the same are disclosed. The electroluminescent display includes a display panel including a plurality of pixels electrically connected to a plurality of data lines and a plurality of gate lines. Each pixel includes a driving element adjusting a current of a light emitting element depending on a gate-to-source voltage, and a switching element supplying a second voltage to the driving element in response to a gate-on voltage of an emission control signal. The switching element is turned off in response to a gate-off voltage of the emission control signal during a real-time compensation time. A source voltage of the driving element is changed during the real-time compensation time.
