1. An electronic device, comprising:
a display comprising pixels; and
a light emitter that emits light through a portion of the display, wherein the portion of the display comprises a first pixel of the pixels and wherein the first pixel comprises:
a first power supply terminal;
a second power supply terminal;
a light-emitting diode having an anode and a cathode;
a drive transistor, wherein the drive transistor and the light-emitting diode are connected in series between the first and second power supply terminals;
a first transistor that is connected between the anode and a first signal line that provides a first bias voltage; and
a second transistor that is connected between the anode and a second signal line that provides a second bias voltage.
