1. A display device, comprising:
an organic light emitting diode (OLED) display panel comprising one or more OLED pixels, each OLED pixel comprising a plurality of sub-pixels and a substrate positioned behind the plurality of sub-pixels with respect to a viewing surface of the OLED display panel;
a proximity sensor having a proximity sensor emitter positioned behind the OLED display panel with respect to the viewing surface of the OLED display panel; and
a proximity emitter mask positioned between the proximity sensor emitter and the plurality of sub-pixels to shield the plurality of sub-pixels from the proximity sensor emitter, the proximity emitter mask comprising patterned metal integrated with printed circuitry on a layer of the substrate.
