摘要： A directional backlight for a transmissive spatial light modulator comprises a waveguide having an input end, first and second, opposed guide surfaces for guiding light along the waveguide, and a reflective end facing the input end for reflecting light from the input light back through the waveguide. An array of light sources that output light predominantly in an emission band and in a conversion band are disposed across the input end of the waveguide and light is directed into respective optical windows in output directions distributed in the lateral direction in dependence on the input positions. To achieve crosstalk suppression, disposed between the input end and the light sources is a reflection reduction element that comprises a filter arranged to absorb light in the conversion band preferentially over light in the emission band, thereby reducing reflections of light incident on the input end after reflection from the reflective end.

摘要： An imaging directional backlight apparatus includes a waveguide and light source array for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure in which steps may include extraction features optically hidden to guided light, propagating in a forward direction. Returning light propagating in a 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 defines the relative positions of system elements and ray paths. A holder portion extends across the light sources and the waveguide, and holds the light sources and the waveguide in position relative to each other. A resilient member behind the light sources resiliently biases the light sources towards the input end of the waveguide.
