1. An electronic display comprising:
an active area, wherein the active area comprises one or more self-emissive pixels for displaying display content on the active area; and
an ambient light sensor (ALS) located beneath the active area, wherein the ambient light sensor is configured to sense ambient light above the active area during an integration period, wherein the integration period is less than a blanking period of a self-emissive pixel of the one or more self-emissive pixels when emission from the self-emissive pixel is less than a threshold luminance value corresponding to a luminance of the self-emissive pixel at a time after the self-emissive pixel is turned off, wherein the ALS is configured to sense crosstalk light included in a gray band emission mask, wherein the crosstalk light corresponds to one or more gray levels representing respective average amounts of light emissions of the one or more self-emissive pixels produced during the integration period.
