Summary: | A pixel circuit includes a selection transistor, a driving transistor, an emissive element, a first capacitor, a reference transistor and a second capacitor. The selection transistor is coupled to a gate line and a data line. A control electrode of the driving transistor is coupled to the selection transistor and a first electrode of the driving transistor is coupled to a power source line. The emissive element emits light according to a current drawn from the driving transistor. The first capacitor is coupled to the driving transistor and an emission signal line. A control electrode of the reference transistor is coupled to a first voltage source. A second electrode of the reference transistor is coupled to the control electrode of the driving transistor. The second capacitor is coupled to a second voltage source and the reference transistor. |
