Patent ID: 7868858

Claim:
A pixel structure, comprising: a light-emitting device having two ends; a first scan line for transferring a first signal; a data line for transferring a data current signal; a first transistor having a gate coupled to the first scan line; a current mirror electrically connected to the light-emitting device, the current mirror comprising: a second transistor having a gate connected to the data line and one of the source and the drain of the first transistor; and a third transistor having a gate coupled to the other of the source and the drain of the first transistor; and a capacitor, having a first end and a second end coupled to the gate of the third transistor and the light-emitting device, respectively, wherein the first end of the capacitor is coupled to the gate of the third transistor while the second end of the capacitor is coupled to one of the source and the drain of the third transistor and to one of the two ends of the light-emitting device without passing through the third transistor.
