Abstract:
An electroluminescent display is disclosed. An electroluminescent display comprises a display panel including a plurality of pixels, each of the plurality of pixels including subpixels. A pixel circuit of each subpixels includes a driving transistor configured to drive the electroluminescent diode, a first switching transistor configured to supply a first voltage to a gate of the driving transistor in response to a first scan signal, a second switching transistor configured to supply a second voltage to the gate of the driving transistor in response to a second scan signal, a third switching transistor configured to supply the second voltage to a first electrode of the driving transistor in response to the second scan signal, a fourth switching transistor configured to supply a first supply voltage to a second electrode of the driving transistor in response to an emission control signal, a first capacitor between a first node connected to the gate electrode of the driving transistor and a second node connected to the second electrode of the driving transistor, and a second capacitor between the second node and a power supply line supplied with the second voltage or the first supply voltage.
