    Abstract: An operation method of a proximity sensor comprises: controlling a light-emitting element by a processing circuit. Such control includes a plurality of light source on and light source off operations. An optical sensor receives light and outputs a sensing signal corresponding to the intensity of the light. The processing circuit computes the sensing signal to produce a sensing result. The plurality of light source on and light source off operations includes a group having two light sources on operations and two light sources off operations. The two light sources on operations in the group or the two light sources off operations in the group are performed consecutively. In this way, the ambient light components of the light source on and off operations may cancel out each other to reduce the ambient light components contained in the sensing results.

    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 light sensing packaging structure and a packaging method thereof is provided, wherein the light sensing packaging structure comprises a substrate provided with a through-hole between a light-emitting element and a light-sensing element; and a cover body covered the substrate. The cover body comprises a shielding part and an extended part. The shielding part is mounted between the light-emitting element and the light-sensing element, and provided with a metal bonding layer on a surface towards the substrate. The extended part is provided with a metal side wall connected to the metal bonding layer. The through-hole is covered with a conductive glue, and the metal junction contacts the conductive glue. Hereby, the present application may reduce the size of the light sensing device, provide a stable packaging, reduce the packaging cost and improve the reliability of the light sensing product.
