More Information
Summary:An electronic device is provided. The electronic device includes a substrate, an optical sensing element, a light-shielding structure, and a microlens. The substrate has a normal direction. The optical sensing element is disposed on the substrate. The light-shielding structure is disposed on the optical sensing element and includes a plurality of light-shielding layers. Each light-shielding layer includes an opening, and centers of the openings are arranged along a first direction and separated from each other. The microlens is disposed on the light-shielding layers and overlaps the opening of the uppermost light-shielding layer. The microlens guides light into an optical channel formed by the openings, so that the optical sensing element has a maximum response value for light with an incident angle that is greater than or equal to 10 degrees and less than or equal to 30 degrees relative to the normal direction.
