Patent ID: 6977470

Claim:
A pixel device of an electroluminescence device comprising: 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; a light emitting diode connected to the second transistor; 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; and a reset circuit for resetting the light emitting diode, comprising a transistor formed across the light emitting diode.
