Abstract: An optical coating includes multiple layers of different materials and thicknesses and is disposed proximate a transparent display cover for an electronic device display. The optical coating transmits most visible light, reflects most non-visible light and substantially absorbs blackbody radiation generated from within the electronic device. The optical coating can be readily removable from the electronic device display either alone or in combination with a removable transparent display cover. The multiple layers comprise two or more materials having alternating low and high indices of refraction. The arrangement and thicknesses of the layers are designed based upon the thickness and optical properties of the transparent display cover. in another embodiment, an internal optical coating. The internal optical coating can also be specially formulated to replace a typical internal anti-reflective coating proximate the visual display unit.
