Patent ID: 7262750

Claim:
A pixel structure, comprising: a light-emitting device; 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 fourth transistor having a gate coupled to the first scan line, one of the source and the drain of the fourth transistor being electrically connected to the drain of the second transistor, and the other of the source and the drain of the fourth transistor being electrically connected to the gate of the second transistor and the data line.
