Abstract
Backlit display systems, such as those employed with LED backlit displays, including those configured for autostereoscopic operation, may employ synchronization between the backlight and the presentation of sequential left and right eye images at a frame rate exceeding approximately 100 Hz. To successfully directionally illuminate isolated frames, the disclosed principles provide for segmenting the directional illumination and introducing a phase shifted, synchronized, pulsed drive scheme for the illumination segments. Accordingly, the principles disclosed herein are directed to segmented directional illumination systems and related techniques for segmented directional backlight illumination.
