Abstract
An optical module is disclosed. The optical module includes a carrier, an optical device disposed over the carrier, and a sensing surface facing away from the carrier. The sensing surface includes a transmissive region and a non-transmissive region adjacent to the transmissive region.
Claims19
An optical module, comprising:
- a carrier having a first surface and a second surface opposite to the first surface;
- a first optical receiver disposed over the second surface of the carrier;
- a first optical emitter disposed over the second surface of the carrier;
- an encapsulant covering the first optical receiver;
- a first light blocking structure disposed over the second surface of the carrier and between the first optical receiver and the first optical emitter;
- a first conductive element penetrating the first light blocking structure and having a surface exposed from the first light blocking structure;
- and
- an electrode exposed from the first surface of the carrier and configured to collect an electrical signal associated with a user of the optical module, thereby providing an ECG function with the first conductive element,
- wherein the encapsulant, the first light blocking structure, and the first conductive element defining a sensing surface facing away from the carrier,
- wherein the sensing surface includes a transmissive region and a non-transmissive region adjacent to the transmissive region.
