More Information
Summary:This relates to an electronic device configured for optical sensing having shared windows and including light restriction designs. The light restriction designs can include one or more of optical layers, optical films, lenses, and window systems configured to reduce or eliminate crosstalk between optical components. A plurality of accepting sections and a plurality of blocking sections can be employed to selectively allow light having an angle of incidence within one or more acceptance viewing angles and block light with angles of incidence outside of the acceptance viewing angles. In some examples, the light restriction designs can include variations in optical and structural properties can allow the light restriction designs to have spatially varying acceptance angles. Variations in structural properties can include, but are not limited to, differences in widths, heights, and/or tilts of the accepting sections and/or blocking sections.
