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: The present application provides a light sensor module, which comprise a display element, a first polarizing element, a light sensor, a transparent layer, and a second polarizing element. The display element emits a display light source. The first polarizing element covers the display element, and blocks a first phase portion of the display light source and allows a second phase portion of the display light source to penetrate. The transparent layer covers the first polarizing element. The light sensor is disposed on one side of the display element or the first polarizing element. The second polarizing element is disposed between the light sensor and the transparent layer and blocks a second phase portion of the display light source.

Abstract: An optical sensing method and an optical sensor module thereof. The optical sensing method includes obtaining an optical signal by sensing with a first optical sensor and a second optical sensor, respectively. The first optical sensor and the second optical sensor have different optical sensing wavelength ranges. Furthermore, a color temperature determination unit receives the optical signals of the first and second optical sensors and calculates a color temperature value by substituting an equation. In this way, the optical sensing method and its optical sensor module can obtain color temperature calculations with high accuracy and can effectively reduce the system computational complexity.
