P‐100: High‐Resolution Multi‐Person Viewing Naked‐Eye 3D Display System Based on Eye Tracking and Spatiotemporal Multiplexing Technology

With the development of naked‐eye 3D display technology, users can freely experience the three‐dimensional effect without glasses, in which the light field display has gradually entered the public's field of vision because of its high‐precision reconstruction of virtual 3D scenes. However, the trade‐off between the number of viewpoints and the 2D display effect is still the bottleneck of this technology. In this paper, a high‐resolution multi‐person stereoscopic display system is realized by dynamic collimation backlight, human eye tracking algorithm and new driving scheme. The main technology is the use of collimated backlight, beam splitting and optical waveguide to realize the time division multiplexing of backlight; With the multi‐person tracking algorithm and the mapping algorithm, the smooth 3D motion parallax is realized. The combination of multi‐person eye tracking technology and spatio‐temporal multiplexing technology makes the spatial resolution greatly improved.
