Beschreibung
Zusammenfassung:	A method of operating an optical proximity sensor of a computer device having a display, where the optical proximity sensor is located beneath or otherwise adjacent to the display. The method comprises obtaining a vertical synchronization signal from a display driver, and synchronizing periodic illumination of a light emitter of the optical proximity sensor with the vertical synchronization signal.
