  • Patent number: 10770602
    Abstract: An optical sensor includes pixels disposed in a substrate and a light collimating layer disposed on the substrate. The light collimating layer includes a first light-shielding layer, first transparent pillars, a second light-shielding layer, and second transparent pillars. The first light-shielding layer is disposed on the substrate. The first transparent pillars through the first light-shielding layer are correspondingly disposed on the pixels. The second light-shielding layer is disposed on the first light-shielding layer and the first transparent pillars. The second transparent pillars through the second light-shielding layer are correspondingly disposed on the first transparent pillars. The top surface area of each of the first transparent pillars is not equal to the bottom surface area of each of the second transparent pillars.

  • Publication number: 20200251506
    Abstract: An optical sensor includes pixels disposed in a substrate. A light collimating layer is disposed on the substrate and includes a transparent layer, a light-shielding layer, and transparent pillars. The transparent layer blanketly disposed on the substrate covers the pixels and the region between the pixels. The light-shielding layer is disposed on the transparent layer and between the transparent pillars. The transparent pillars penetrating through the light-shielding layer are correspondingly disposed on the pixels.

  • Publication number: 20200249490
    Abstract: An optical sensor includes a plurality of pixels disposed in a substrate and a light collimating layer. The light collimating layer is disposed on the substrate. The light collimating layer includes a light-shielding layer, a plurality of transparent pillars, and a plurality of first dummy transparent pillars. The light-shielding layer is disposed on the substrate. The plurality of transparent pillars pass through the light-shielding layer and are disposed correspondingly on the plurality of pixels. The plurality of first dummy transparent pillars that pass through the light-shielding layer are disposed on a first peripheral region of the light collimating layer, wherein the plurality of first dummy transparent pillars surround the plurality of transparent pillars from a top view.
