Abstract:
1. A pixel structure, comprising: a light-emitting device, having a first electrode and a second electrode; 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; and a current mirror electrically connected to the light-emitting device, the current mirror comprising: wherein the first electrode of the light-emitting device is coupled to a second voltage source and the second electrode of the light-emitting device is coupled to the other of the source and the drain of the third transistor, a voltage level provided by the second voltage source is substantially greater than a voltage level provided by the first voltage source, and the light-emitting device emits the light according to the first voltage source and the second voltage source.
