Multiview backlighting employing fluorescent multibeam elements

A multiview display comprising:

• an array of multiview pixels configured to provide different views of a multiview image, a multiview pixel comprising a plurality of view pixels configured to modulate a corresponding plurality of directional light beams having different principal angular directions corresponding to view directions of the different views;
• a light guide configured to guide light as guided light;
• and
• an array of fluorescent multibeam elements, a fluorescent multibeam element of the element array comprising a fluorescent material and being configured to provide emitted light from the guided light, the emitted light having a color-tailored emission pattern and comprising the plurality of directional light beams,
• wherein the color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the view pixel plurality;
• wherein the fluorescent multibeam element comprises a plurality of multibeam sub-elements having different fluorescent emission colors from one another;
• and
• wherein the plurality of multibeam sub-elements includes two multibeam sub-elements that overlap in adjacent regions of the two multibeam sub-elements.

A method of multiview backlight operation, the method comprising:

• guiding light along a length of a light guide;
• and
• emitting light by fluorescent emission from the guided light using an array of fluorescent multibeam elements, the emitted light comprising a plurality of directional light beams having different principal angular directions corresponding to respective different view directions of a multiview display, a fluorescent multibeam element of the array comprising fluorescent material and having a color-tailored emission pattern,
• wherein the color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display;
• wherein the fluorescent multibeam element comprises a plurality of multibeam sub-elements having different fluorescent emission colors from one another;
• and
• wherein the plurality of multibeam sub-elements includes two multibeam sub-elements that overlap in adjacent regions of the two multibeam sub-elements.
