  • Publication number: 20180277523
    Abstract: Emissive display devices having LED sources with super-lambertian radiation patterns. An exemplary emission source may have a half-emission-cone-angle of less than 40°. A system, such as an augmented reality display system, employing such an emissive display device may display a reduction in power of up to three times relative to LED sources with a lambertian radiation pattern. In some systems, such as augmented reality display systems, the optical path down stream of such an emissive display device may be simplified and/or dimensionally scaled, and/or manufactured to lower tolerances. For example, a discrete collimating lens may be eliminated from the optical path of such an emissive display device.
