Abstract: A display device and a method for operating a display device disclosed herein include transmitting a proximity signal from a proximity sensor, the proximity sensor being positioned under a lower surface of a surface layer with an illumination component being positioned between the surface layer and the proximity sensor, in response to the illumination component being deactivated, receiving a reflected proximity signal based on the proximity signal, determining a proximity value based on the reflected proximity signal and modifying an operation of the display device based on the proximity value. The modifying the operation of the display device includes any one or a combination of activating the illumination component, deactivating the illumination component, or modifying a property of the illumination component.

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.

Abstract: Techniques, devices, and systems disclosed herein include detecting a vertical synchronization (VSYNC) signal cycle, determining a high frequency trigger pulse based on detecting an illumination component's pulse width modulation (PWM) signal, the high frequency trigger pulse corresponding to the illumination component's deactivation times, receiving a delay time period and activating a first sensor, at a first time, within the VSYNC signal cycle, the first time determined based on the high frequency trigger pulse and the delay time period. The first sensor may sense a first sensor reading and may be deactivated after being activated. A display setting may be adjusted based at least on the first sensor reading and the illumination component may be activated after the first sensor is deactivated.
