  • Patent number: 6787976
    Abstract: In a luminous display element, a retro-reflector is provided on the back side of an organic EL layer which includes an emission layer whose state changes between an emission state and a non-emission state. The retro-reflector includes a corner cube array, and reflects incident light in the same direction as an incident direction. A unit structure of the corner cube array is a form of a triangular pyramid which is made up of rectangular equilateral triangles having three faces, and a light shielding process is performed on the periphery of a base angle of the rectangular equilateral triangle. Thus, it is possible to prevent an image from being reflected, so that it is possible to provide the luminous display element whose contrast ratio and the utilization efficiency of emission are high.

  • Patent number: 6784603
    Abstract: A light source useful for a wide variety of lighting applications such as signage, architectural or automotive designs, as well as cosmetic and/or functional features for other products can be created by combining a light collector comprising a sheet of material having a fluorescent substance incorporated therein and an optical element juxtaposed adjacent the collector. Light incident on the collector induces fluorescence that is trapped by total internal reflection, concentrated, and radiated from an edge of the collector. The size of collector plate with respect to its thickness is such that it provides an intensified image along its edge that is readily visible during both daytime and nighttime. The optical element modifies the distribution of light output from an edge of the collector. The optical element is preferably configured to decrease divergence of light emitted from the edge. The optical element may also direct the light emitted from the collector above or below the plane of the collector.
