Abstract
Multiview backlighting having a color-tailored emission pattern provides 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 color-tailored multibeam element. The color-tailored multibeam element is configured to provide emitted light having the color-tailored 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. The color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display.
