Abstract:
A proximity sensing device having a light emitting assembly including a light emitting device for proximity sensing positioned on a substrate and a light emitting lens positioned along a side of the light emitting device opposite the substrate and a light receiving assembly having a light receiving device positioned on the substrate and a receiving lens positioned along a side of the light receiving device opposite the substrate. A mid wall is positioned between the light emitting assembly and the light receiving assembly which includes a crosstalk controlling portion positioned between the light emitting lens and the light receiving lens that is configured to reduce optical crosstalk between the light emitting assembly and the light receiving assembly.
