Abstract
A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To determine whether the light emitter has caused these artifacts, a display light sensor under the display may measure backside light leakage from the display. Based on the measured backside light leakage, the display light sensor or control circuitry may determine whether artifacts in the display exceed a predetermined acceptable artifact range. If the artifacts exceed this range, the artifacts may be mitigated. To mitigate the artifacts, the light emitter and/or the display may be adjusted. For example, the timing and/or dosage of the light emitter, the acceptable artifact range, and/or the timing of display content may be adjusted. In this way, the display light sensor may be used to form a closed-loop system to determine whether artifacts are present in the display and to mitigate those artifacts.
