Transmissive barrier in a transmissive sheet

摘要

Approaches enable a component such as a camera of a computing device to be collocated, or otherwise placed in proximity under the same cover sheet of material with an light source. A cover sheet can include a transmissive barrier positioned therein. The transmissive barrier can include at least one of a light scattering or light blocking feature. A light source and camera sensor can be positioned on a same side of the cover sheet and the transmissive barrier can be positioned between the light source and the camera such that light reflected from the light source by a portion of the cover sheet towards the camera is at least scattered, refracted, diffracted, blocked, or otherwise reduced using a determined pattern, layer, or other such feature in order to reduce an amount of light of the light source that is reflected from a surface or feature of the cover sheet and is detected by the camera.

主权项

1. A computing device, comprising:
at least one processor; a light source; a camera; a cover sheet that includes a light filtering feature, the light filtering feature including a scattering pattern, wherein the scattering pattern includes at least one diffraction pattern formed at a predetermined angle relative to a light source, and wherein a first diffraction pattern includes a first set of diffraction features at a first angle and a second diffraction pattern includes a second set of diffraction features at a second angle, the second angle different from the first angle; and a memory device including instructions that, when executed by the at least one processor, cause the light source to emit light in a first direction through the cover sheet, the instructions when executed further causing the camera to detect a subset of the light transmitted in a second direction through the cover sheet, wherein the second direction is substantially opposite to the first direction, wherein the light source and the camera are positioned on a same side of the cover sheet, and wherein the scattering pattern is positioned to scatter the subset of the light reflected by the cover sheet in the second direction toward the camera, to reduce an amount of the subset of the light detected by the camera.
