AI Technical Summary
Existing light field display technologies struggle to achieve high-definition and high-angle resolution multi-view light field displays, and traditional metasurface designs suffer from color difference and low efficiency.
Using three-dimensional holographic pixels composed of monochromatic hogels, a monochromatic hogel array is formed by partitioning the monochromatic hogels with directional optical elements. By utilizing the subwavelength thickness of the nanostructure and a specific lattice design, efficient light field display is achieved.
It achieves high-definition and high-angle resolution multi-view light field display, improves display efficiency, eliminates color difference, reduces dependence on polarized light source, and enhances the depth of field and field of view of the display.
