Abstract: A circuit board includes a plurality of pixel areas. Each pixel area includes a plurality of electrode pad groups. The electrode pad groups are arranged in a first direction. Each of the electrode pad groups includes a first electrode pad, a second electrode pad, and a third electrode pad. The first electrode pad, the second electrode pad, and the third electrode pad are arranged in a second direction. The second direction is different from the first direction. The first electrode pad is disposed between the second electrode pad and the third electrode pad. The first electrode pad is configured to provide a first voltage potential. The second electrode pad and the third electrode pad are configured to provide a second voltage potential. The first voltage potential is different from the second voltage potential.

Abstract: A light shielding element substrate includes a substrate, a transparent island structure and a first light shielding layer. The transparent island structure is located on the substrate. The first light shielding layer is located on the transparent island structure. The first light shielding layer is overlapping with a part of the top surface of the transparent island structure. The first light shielding layer has a first through hole overlapping the top surface of the transparent island structure.

Abstract: A fingerprint sensing apparatus including a first substrate, a light sensing structure, a second substrate, a lens layer, a filler, and a first light shielding layer is provided. The light sensing structure is disposed on a sensing area of the first substrate. The lens layer is disposed on the second substrate. The lens layer has multiple first convex portions and a first concave portion. The filler is disposed between the lens layer and the light sensing structure. The refractive index of the filler is greater than the refractive index of the lens layer. The first light shielding layer is disposed between the second substrate and the lens layer. A solid of the first light shielding layer overlaps the first convex portions of the lens layer. An opening of the first light shielding layer overlaps the first concave portion of the lens layer.
