Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, a display pixel that overlaps the light emitter may include a transistor that provides a current sink to divert leakage current away from the light-emitting diode in that pixel. A shielding layer may be interposed between the light emitter and a display pixel. The shielding layer may block light from the light emitter. The shielding layer may have an opening that exposes one transistor in the pixel to the light from the light emitter. Pixels that overlap the light emitter may have larger anodes than pixels that do not overlap the light emitter.
