A concealing structure to at least partially conceal a sensor, light emitter or other component by at least partially preventing reflection of external light by an underlying structure. In some examples, this function is performed by a two-component masking assembly, the masking assembly including a linear polarizer to cause linear polarization of light which passes from the exterior of the device to an underlying component, and a wave plate to shift the axis of any reflected polarized light. In many cases, a high density optical fluid will further be included within the masking assembly to minimize reflections from the other components of the assembly. 1. A device comprising:a display screen;a body that defines a border area adjacent a periphery of the display screen;an optical component mounted in the border area of the body; and a linear polarizer configured to cause linear polarization of light which passes through the linear polarizer to the optical component;', 'a wave plate mounted substantially parallel to the linear polarizer and located between the linear polarizer and the optical component, to cause at least partial circular polarization of linearly polarized light which passes through the wave plate to the optical component., 'a laminate member mounted on the border area to cover the optical component from view, the laminate member comprising2. The device of claim 1 , further comprising a frame member that defines an aperture in alignment with the optical component to allow passage of light through the aperture on to the optical component claim 1 , the frame member having an outer surface facing away from the optical component claim 1 , the outer surface of the frame member around the aperture having a dark appearance.3. The device of claim 2 , wherein the outer surface of the frame member has a black appearance.4. The device of claim 3 , wherein the frame member is a layered element forming part of the laminate member.5. The device of claim 4 , wherein ...
