OPTICAL COATING FOR ELECTRONIC DEVICE DISPLAY
First Claim
1. An electronic device display, comprising:
- a visual display unit adapted to provide a visual display to a user of an electronic device associated with the electronic device display;
a transparent display cover situated proximate to the visual display unit; and
an optical coating disposed proximate said display cover, said optical coating including a plurality of layers of different materials and thicknesses, wherein said optical coating is adapted to transmit therethrough most of all visible wavelengths of light collectively, reflect therefrom most of all non-visible wavelengths of light collectively, and to absorb most blackbody radiation generated from within the electronic device.

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, and can include 36 or more layers, each having a thickness ranging from 10 to 400 nanometers. The arrangement and thicknesses of the layers are designed based upon the thickness and optical properties of the transparent display cover.

16. A selectively transmissive optical system, comprising:
-
a transparent panel having a first surface and second surface; a first plurality of optically transmissive layers, each formed from the same first material having a first index of refraction; and a second plurality of optically transmissive layers, each formed from the same second material having a second index of refraction, wherein the second plurality of optically transmissive layers is interleaved with the first plurality of optically transmissive layers to form a collective optical coating that is situated proximate to the first surface of the transparent panel, wherein said optical coating is adapted to transmit therethrough most of all visible wavelengths of light collectively, to reflect therefrom most of all non-visible wavelengths of light collectively, and to absorb substantially blackbody radiation generated from beyond the second surface of the transparent panel, and wherein said optical coating is readily removable from the transparent panel. - View Dependent Claims (17, 18, 19)
