    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: A module comprises 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.
