  • Patent number: 11698549
    Abstract: A multi-view (MV) display panel includes a flat panel display (FPD) having FPD pixels, and lenses configured to image the FPD. Each of the FPD pixels, when imaged through one of the lenses, forms a beamlet that is emitted in a direction unique from other beamlets formed by other FPD pixels through the lens. The lens and the FPD pixels which, when imaged through the lens, form beamlets emitted in different directions collectively configure an MV pixel. Each of the FPD pixels includes multiple sub-pixels. The MV display panel also includes a diffuser arranged between the FPD and the lenses, and a light block configured to isolate a diffusion of the multiple sub-pixels of each FPD pixel from its neighboring FPD pixels. The FPD may be backlit using custom lighting and optics. Lens elements may be staggered in a manner that facilitates assembly of the lenses.
