Abstract

Three-dimensional (3D) display is a very attractive research direction, and have potential in many areas. The cutting-edge autostereoscopic display technology allows glasses-free experience, but still be limited in the lab because of the small eye space and high cross-talk. The only commercially available technology is still polarization-interlaced stereoscopic display. The disadvantages are the bulk-cost of the polarization module, low-light efficiency, and the high crosstalk. Besides, the color gamut in two-dimensional (2D) display is very important to display systems, which represents the color rending ability, and at present limited by three primaries. Herein, we demonstrate a six-primary-laser projection system compatible with 3D and 2D display, achieve great 3D viewing experience with crosstalk lower than 1% by time-multiplexed stereoscopic display technology and spectral coating glasses. In addition, we study the volume color gamut of this system in 2D working mode. The color gamut is greatly increase to an amazing 178.4% NTSC, owing to the application of multiprimary color and narrow spectral line-width laser source. This system is also provide the possibility for us to study the color gamut involving binocular fusion in 3D working mode in future.
