Abstract
Examples are disclosed that relate to mitigating unintended OLED display emissions arising from a proximity sensor emitter located behind an OLED display panel. One example provides a display device comprising an OLED display panel, a proximity sensor having a proximity sensor emitter positioned behind one or more OLED pixels of the OLED display panel with respect to a viewing surface of the OLED display panel, and a proximity emitter mask positioned between the proximity sensor emitter and the one or more OLED pixels to shield the one or more OLED pixels from the proximity sensor emitter.
