Publication number: 20170235039Abstract: An integrated back light unit can include a light guide plate having a non-uniform distribution of extraction features. The non-uniform distribution of the extraction features can be provided by an extraction-feature-free region in proximity to a light emitting device, and/or by a variable density of the extraction features that changes with distance from the light emitting device. Additionally or alternatively, the light guide unit can include a heterogeneous reflectivity surface that has a different reflectivity at proximity to the light emitting device assembly than at a distal portion of the light guide unit. The different reflectivity may be provided by a specular reflective material, diffusive reflective material, or a light absorbing material. The non-uniform distribution of extraction features and/or the heterogeneous reflectivity surface can be employed to enhance brightness uniformity of the reflective light and/or to control the temperature distribution within the light guide unit.Type: ApplicationFiled: August 10, 2015Publication date: August 17, 2017Inventors: Ronald KANESHIRO, Ping WANG, Frank PATTERSON, Clinton CARLISLE, Michael JANSEN

Publication number: 20170235040Abstract: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources and hence defines the relative positions of system elements and ray paths. The uncorrected system creates non-illuminated void portions when viewed off-axis preventing uniform wide angle 2D illumination modes.Type: ApplicationFiled: May 4, 2017Publication date: August 17, 2017Inventors: Michael G.
