A pixel device of an electroluminescence device that comprises a scan line and a data line corresponding to the pixel device, a voltage signal transmitted over the scan line having a first state and a second state, a current mirror circuit further comprising a first transistor including a gate, and a second transistor including a gate coupled to the gate of the first transistor, a first current flowing through the first transistor to the data line being provided in response to the first state of the voltage signal, a second current proportional to the first current flowing through the second transistor in response to the first state of the voltage signal, a light emitting diode connected to the second transistor, and a capacitor being charged to a voltage level in response to the first state of the voltage signal by the first current, and maintaining the second current during the second state of the voltage signal.
