3d light field led-wall display

Abstract

Modular 3D light field LED wall display composed of uniform panels (), connected to each other mechanically and electrically, each of the uniform panels () comprising—a LED backplane () comprising pixels (P), each incorporating multiple LED emitters (), —an optical means placed over the LED emitters () to direct multiple light beams into multiple directions from each pixel (P), —the panels further comprising LED driver electronics () and connectors (), in which—the LED emitters are individually controlled LED emitters arranged in a predetermined pattern of LED emitters within a LED pixel, —the optical means is realized as a panel optics () having the same size and form as the panel, comprising multiple optical surfaces, forming a lens array, containing integer number of straight oriented lenslets () with straight edges, corresponding to the pixel (P) arrangement, forming a seamlessly tile-able array, —the light beam from each LED emitter () is directed into one direction by the panel optics (), and the light beams (L. . . L) emitted from the pixel (P) into the multiple directions cover a contiguous angular range a in a single lobe, where each of the light beams having a divergence (δ) in order to provide a continuously changing 3D vision, —the multiple light beams (L. . . L) from all the pixels (P) generate a continuous 3D light field providing natural 3D view over a wide field-of-view (FOV) with a high angular resolution. Both large-scale horizontal-only-parallax (HOP) 3D light field LED wall displays and full-parallax panels based on backplanes with micro-LED arrays are described. Disclosed is further a method for displaying 3D images on a 3D LED wall display.
