20150253487 | REFLECTIVE DISPLAY COMPRISING A FRONTLIGHT WITH EXTRACTION FEATURES AND A LIGHT REDIRECTING OPTICAL ELEMENT - A display includes a reflective spatial light modulator having a reflective surface, a lightguide comprising a core layer, a first cladding layer, and a light emitting region comprising a plurality of light extraction features arranged in a pattern that varies spatially in the light emitting region to frustrate totally internally reflected light propagating within the core layer such that light exits the core layer in the light emitting region into the first cladding layer. A light redirecting optical element is optically coupled to the second side of the first cladding layer, and includes a plurality of light redirecting features directing frustrated totally internally reflected light from the plurality of light extraction features toward the reflective spatial light modulator. | 09-10-2015 |
20150219834 | DISPLAY WITH A FILM-BASED LIGHTGUIDE AND LIGHT REDIRECTING OPTICAL ELEMENT - 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 through a cladding region toward a light redirecting optical element that redirects the light toward a reflective spatial light modulator. A method of producing a display is also disclosed. | 08-06-2015 |
20150078035 | DEVICE COMPRISING A FILM-BASED LIGHTGUIDE AND COMPONENT WITH ANGLED TEETH - A device disclosed herein includes a component having a frame and an array of protruding teeth extending from the frame. Each tooth of the array of protruding teeth has an angled edge. The device also includes a lightguide formed from a film. The lightguide includes an array of strips extending from an area of the film. The array of strips is positioned adjacent the array of protruding teeth, and the component at least partially restrains the film when each strip of the array of strips is folded across an angled edge of a corresponding tooth of the array of protruding teeth. | 03-19-2015 |
20140063853 | FILM-BASED LIGHTGUIDE INCLUDING A WRAPPED STACK OF INPUT COUPLERS AND LIGHT EMITTING DEVICE INCLUDING THE SAME - A lightguide includes a plurality of coupling lightguides extending from a body of film. The plurality of coupling lightguides are folded and arranged in a stack, wherein a region of the film is wrapped around at least one side of the stack of the plurality of coupling lightguides. | 03-06-2014 |
20140056028 | LIGHT EMITTING DEVICE WITH ADJUSTABLE LIGHT OUTPUT PROFILE - A device includes a film-based lightguide and a film adjustment mechanism configurable to adjust an orientation of a region of the film-based lightguide such that an angular light output profile from the device changes when a light source emits light that travels in a waveguide condition through the film-based lightguide. | 02-27-2014 |
20130250618 | LIGHT EMITTING DEVICE WITH LIGHT MIXING WITHIN A FILM - In one embodiment, a light emitting device comprises an array of legs extending from a body of film with the bounding edges of the legs stacked, a first light source emitting light of a first color and a second light source emitting light of a second color into the stacked bounding edges where the light emitting region defined within the body is configured to extract light of a third color. In another embodiment, a light emitting device comprises three light sources positioned to direct light into a stacked array of bounding edges. In one embodiment, a method of generating light of adjustable color exiting a surface of a film is disclosed. | 09-26-2013 |
20130155723 | Replaceable lightguide film display - In one embodiment, a device includes a light transmitting film defining a body and having opposing faces with a thickness between the opposing faces not greater than 0.5 millimeters. A first region is defined within the body representing a region of one or more of a pattern, 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. The first region includes a plurality of light extraction features that redirect a portion of light traveling within the film in a waveguide condition that mixes within the legs and the body out of one or more of the opposing faces of the film in the first region. A method of producing a device is also disclosed | 06-20-2013 |
20120287674 | ILLUMINATION DEVICE COMPRISING ORIENTED COUPLING LIGHTGUIDES - A lightguide includes a film including a body with opposing faces having a thickness not greater than 0.5 millimeters therebetween. An array of strips has an array direction extending from the body of the film, wherein each strip in the array of strips has a curved or angled lateral edge. A method for manufacturing a lightguide is also disclosed. | 11-15-2012 |
20110227487 | Light emitting display with light mixing within a film - In one embodiment, a light emitting device comprises an array of legs extending from a body of film with the bounding edges of the legs stacked, a first light source emitting light of a first color and a second light source emitting light of a second color into the stacked bounding edges where the light emitting region defined within the body is configured to extract light of a third color. In another embodiment, a light emitting device comprises three light sources positioned to direct light into a stacked array of bounding edges. In one embodiment, a method of generating light of adjustable color exiting a surface of a film is disclosed. | 09-22-2011 |
