Abstract
Multiview backlighting employs a fluorescent multibeam element having a color-tailored emission pattern to provide directional light beams corresponding to a plurality of different views of a multiview image. A multiview backlight includes a light guide configured to guide light as guided light and a fluorescent multibeam element. The fluorescent multibeam element includes a fluorescent material and is configured to provide emitted light having a color-tailor emission pattern from the guided light. The emitted light includes a plurality of directional light beams having different principal angular directions corresponding to respective different view directions of a multiview display and the color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display.
