Abstract: There is provided an optical sensor package including a substrate, a base layer, an optical detection region, a light source and a light blocking wall. The base layer is arranged on the substrate. The light detection region and the light source are arranged on the base layer. The light blocking wall is arranged on the base layer, and located between the light detection region and the light source to block light directly propagating from the light source to the light detection region.

Abstract: An optical sensor package module and a manufacturing method thereof are provided. The optical sensor package module includes a substrate, a sensor chip and a shielding assembly. The sensor chip is disposed on the substrate and includes an array of pixels located at a top side thereof for receiving light. The shielding assembly surrounds the sensor chip for limiting influx of light onto the sensor chip, and the shielding assembly has a first aperture to expose at least a first subset of the pixels that is configured to receive corresponding light.

Abstract: The present disclosure discloses an optical module package structure and method thereof. The optical module includes a substrate, a shield, a photosensitive unit and a cover. The shield is disposed on the top of the substrate and forms a first housing space with the upper surface of the substrate. The photosensitive unit is disposed on the substrate and located in the first housing space. The shield has a light-receiving part above the photosensitive unit. At least one notch is on the outer surface of the shield. A cushion is disposed on the notch and protrudes on the upper surface of the shield. The cover is disposed on the cushion(s) and kept a constant distance to the upper surface of the shield by contacting with the cushion(s).

Abstract: An optical sensing module capable of providing a multi-directional optical sensing function teaches that the optical sensing module can be fixed on a circuit board via a bridging medium. The optical sensing module includes a supporter, a photosensitive component and a connecting component. The supporter includes a base and several lateral portions. The lateral portions are bent from edges of the base to form an accommodating space. The photosensitive component is disposed inside the accommodating space to receive an optical signal passing into an opening of the accommodating space. The connecting component is disposed on the supporter and includes a conductive terminal. The supporter is connected with the bridging material via the conductive terminal to stand on the circuit board by one of a plurality of sensing directions.
