摘要： In embodiments of this invention, light emitting devices comprise film-based lightguides comprising at least one light input coupler and an array of coupling lightguides that are folded or bent and disposed substantially above one another. The edges of the coupling lightguides may form part of a light input surface. The light emitting device may comprise more than one light input coupler and the film may be less than 500 microns in thickness. In embodiments of this invention, methods of manufacturing lightguides and light input couplers comprise steps that translate linear fold regions of the coupling lightguides relative to each other such that the coupling lightguides are bent or folded above each other. In other embodiments of this invention, an electroluminescent sign, light fixture, frontlight for a reflective display, or a backlight for a transmissive display comprises a lightguide and light input coupler comprising coupling lightguides.

摘要： A device includes a light transmitting film defining a lightguide region. A first region is defined within the lightguide region representing a region of one or more of an indicia, a graphic, and an image that is visible by light extraction when illuminated by light propagating within the film in a waveguide condition, wherein the first region includes a plurality of light extraction features that redirect a portion of light traveling within the film in a waveguide condition out of a first face of the opposing faces of the film in the first region, and the first region has a luminance less than 50 cd/m2 when illuminated with 1000 lux of diffuse light when disposed on an opening of a light trap box comprising a plurality of walls and a black, light absorbing material lining the plurality of walls. A method of making or producing a device is also disclosed.

摘要： A reflective display includes a reflective spatial light modulator and a frontlight. The frontlight includes a lightguide formed from a film. The lightguide includes an array of coupling lightguides continuous with a lightguide region of the lightguide. One or more light sources emit light into the array of coupling lightguides. Light from each coupling lightguide combines and totally internally reflects within the lightguide region. Light extraction features frustrate totally internally reflect light within the lightguide region such that the light exits the lightguide toward the reflective spatial light modulator in a light emitting region of the film. A cladding region is optically coupled to the lightguide so light from the light source propagates into the cladding region. A light extracting region is operatively coupled to the cladding region opposite the lightguide, and light in the cladding region is extracted. A method of producing a display is also disclosed.
