Abstract: The present invention provides an ambient light sensing method and an ambient light sensor. The ambient light sensing method comprises a light sensing device sensing the light passing through an optical filter and giving an optical signal value, and an operational unit receiving the optical signal value and calculating an ambient light illuminance value according to the optical signal value. Accordingly, the ambient light sensing method and the ambient light sensor according to the present invention can give the ambient light illuminance value with more accuracy and ensure low influence of opaque ink on ambient light sensing.

Abstract: A light sensor and a control method thereof are disclosed. The light sensor comprises a light-emitting element, a first light-sensing unit and a second light-sensing unit. The light-emitting element generates an emission signal. The light-sensitive characteristic of the first light-sensing unit corresponds to a first wavelength range. The light-sensitive characteristic of the second light-sensing unit corresponds to a second wavelength range, which is different from the first wavelength range. In this way, when the emission signal is reflected by an object and received by the first light-sensing unit and the second light-sensing unit, the type of the object may be determined based on the difference between the signal sensed by the first light-sensing unit and the signal sensed by the second light-sensing unit.

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.
