Proximity sensor module

摘要

A proposed proximity sensor module comprises a light emitting device (1) and a photo-detector (3) covered by a cover (2). The light emitting device is being designed for emitting light into the cover. Furthermore, the photo-detector is being designed for detecting light scattered and/or reflected by the cover. The cover comprises a dye-based ink layer (4) which, at least partly, covers a surface facing the light emitting device and the photo-detector. The ink layer is being translucent to the light emitted by the light emitting device.
