Abstract
Devices, methods, and systems for detecting proximity. A first light emitter emits light for a first time period while a light detector is not sensing. A second light emitter emits light for a second time period while the light detector is sensing. In some implementations, the first light emitter directly illuminates the light detector during the first time period, whereas the second light emitter is obstructed from directly illuminating the light detector during the second time period. In some implementations, the first light emitter is obstructed from illuminating a display during the first time period, and the second light emitter is obstructed from directly illuminating the light detector during the second time period. In some implementations, the first light emitter emits the light during the first time period such that the light detector maintains a linear responsivity during the second time period.
