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.
Claims20
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, wherein the display device is configured to,
- determine an emission pattern comprising one or more non-emissive states and one or more emissive states of the one or more OLED pixels,
- wherein each of the one or more non-emissive states comprises a temporal location determined from touch sensor data samples received from a display touch sensor of the display device, and
- during a call event, control the proximity sensor emitter to emit during at least a portion of the one or more non-emissive states of the one or more OLED pixels, and not emit during the one or more emissive states of the one or more OLED pixels.
A method enacted on a display device comprising an organic light emitting diode (OLED) display panel and 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, the method comprising:
- determining an emission pattern comprising one or more non-emissive states and one or more emissive states of the one or more OLED pixels,
- wherein determining the emission pattern of the one or more OLED pixels comprises determining a temporal location for each of the one or more non-emissive states from ambient light data samples received from an ambient light sensor of the display device, and
- during a call event, controlling the proximity sensor emitter to emit during at least a portion of the one or more non-emissive states of the one or more OLED pixels, and not emit during the one or more emissive states of the one or more OLED pixels.
A display device, comprising:
- an OLED display panel;
- a proximity sensor having a proximity sensor emitter positioned behind one or more OLED pixels of OLED display panel with respect to a viewing surface of the OLED display panel;
- and
- a patterned metal layer forming mask regions 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, wherein the display device is configured to,
- determine an emission pattern comprising one or more non-emissive states and one or more emissive states of the one or more OLED pixels,
- wherein each of the one or more non-emissive states comprises a temporal location determined from touch sensor data samples received from a display touch sensor of the display device, and
- during a call event, control the proximity sensor emitter to emit during at least a portion of the one or more non-emissive states of the one or more OLED pixels, and not emit during the one or more emissive states of the one or more OLED pixels.
