Abstract: An electronic display may include an ambient light sensor (ALS) located beneath an active area to sense ambient light above the active area. The ALS may have multiple response channels to perform fast sensing integration, which is synchronized with blanking periods of a pixel on the active area. An emission mask and a heat map may be generated for the ALS and used to generate a calibrated heat map for the ALS. The calibrated heat map of the ALS is used with display content to calculate a crosstalk compensation for the ALS.
