Abstract
Methods, systems, computer-readable media, and apparatuses for cover-glass optical isolation for optical touch and fingerprint sensing are presented. One disclosed display assembly includes a cover glass layer; a low refractive index (LRI) layer coupled to a surface of the cover glass layer; a display layer coupled to the LRI layer; a prism structure; and a camera comprising an image sensor optically coupled to the prism structure to capture an image of a fingerprint based on light reflected from a fingertip and propagated within the cover glass layer and directed towards the camera using the prism structure, wherein the cover glass layer defines an overhang region that extends beyond the LRI layer and the display layer, and wherein the prism structure is coupled to the surface of the cover glass layer on the overhang region.
