Patent attributes
Embodiments relate to a pixel circuit of a display with a pixel level burn-in compensation. The pixel circuit includes a light-emitting diode (LED), a first driving transistor between a voltage source and the LED, an enable 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 enable transistor turns on responsive to a voltage level at an anode of the LED increasing to a threshold voltage level. 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 electrode of the second driving transistor via the enable transistor.
