Abstract

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. The system may be corrected to remove this non uniformity at wide angles through the introduction of additional sources away from the system s object plane additional imaging surfaces and/or by altering ray paths.
