Abstract: An optical sensor module and a packaging method thereof are disclosed, wherein the optical sensor module comprises a substrate having a light sensing element; and a housing made of a transparent material. The housing is connected to the substrate and covers the light sensing element. The housing has a light-receiving area facing the light sensing element, and the inner surface of the housing toward the substrate is provided with a light-shielding coating in a portion outside of the light-receiving area. In this way, optical components such as the light sensor can be effectively protected, and still retain the effect of avoiding noise light interference with the light sensor module.

Abstract: A light sensor and a control method thereof are revealed. The light sensor comprises a first light-emitting element, a second light-emitting element and a light-sensing element. The first light-emitting element is used to generate a first emitting signal. The first emitting signal has an optical wavelength within a first wavelength range. The second light-emitting element is used to generate a second emitting signal. The wavelength of the second emitting signal has an optical wavelength within a second wavelength range. The first wavelength range is different from the second wavelength range. Thereby, a control circuit sequentially controls the first light-emitting element and the second light emitting-element to emit the first emitting signal and the second emitting signal. When the first emitting signal and the second emitting signal are reflected by an object and received by the light-sensing element, the control circuit may determine the type of the object based on the signal sensed by the light-sensing element.

Abstract: A package structure with an optical barrier is provided. An emitter for emitting an optical signal and a detector for receiving the optical signal are disposed on a substrate. The optical barrier is disposed between the emitter and the detector for shielding the excess optical signal. A package material is used to completely cover the optical barrier, the emitter and the detector so that the optical barrier is completely disposed within the package material.
