METHOD OF REDUCING EFFECT OF STRAY LIGHT IN OPTICAL SENSOR - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18301338 Titled 'METHOD OF REDUCING EFFECT OF STRAY LIGHT IN OPTICAL SENSOR'
Simplified Explanation
The abstract describes an optical sensor that includes a light emitting unit and a light receiving unit mounted on a substrate. It also includes an electrically conductive pattern, a resist layer, and a light shielding layer. The purpose of the light shielding region is to block stray light from reaching the substrate.
Original Abstract Submitted
An optical sensor includes a light emitting unit configured to emit and output light. a light receiving unit configured to receive light, a substrate on which the light emitting unit and the light receiving unit are mounted, an electrically conductive pattern including a land to be electrically connected to an electrode of the light emitting unit, a resist arranged as a layer above the electrically conductive pattern or the substrate, a light shielding layer provided as a layer above the resist, and a light shielding region formed by a portion of the land and a portion of the light shielding layer overlapping in the direction of the normal of a mounting surface of the substrate, to shield stray light directed towards the substrate from the light emitting unit, the light shielding region.
