Abstract
Embodiments of the present disclosure relate to a pixel circuit with a burn-in compensation. The pixel circuit includes a light-emitting diode (LED), a first driving transistor between a voltage source and the LED, a switching transistor coupled to a gate electrode of the first driving transistor, and a second driving transistor connected between the voltage source and the LED. The first driving transistor provides first current from the voltage source to the LED according to a gate voltage of the first driving transistor. The switching transistor is turned on after receiving an enable signal. The second driving transistor provides second current from the voltage source to the LED according to a version of the gate voltage of the first driving transistor received at a gate of the second driving transistor via the switching transistor.
