In order to get more natural 3D sensation from displays, many researchers and manufacturers were attracted to invest in the development of 3D display technology in recent years. The traditional projection type polarized stereoscopic displays need to wear glasses, and the parallax barrier auto-stereoscopic display can not make in direct projection. Consequently we proposed a new kind of projection type auto-stereoscopic display combining the advantages of both projection type’s polarized stereoscopic display and parallax barrier auto-stereoscopic display.
A new kind of large size directly projection type auto-stereoscopic 3D display was designed, which includes a polarization projector, parallax pattern polarizer, quarter wave plate and AgO screen. Furthermore, the function of pattern polarizer is parallax barrier, which could separate the left and right eye images for observers. The crosstalk is less than 5% in simulation for direct vision. The experiment result shows that the crosstalk is less than 20% for direct viewing. The advantages of this structure is easy to fabricate, low crosstalk, large panel size(>50-inch), high brightness and dose not need to wear glasses, it can be used in large size movie theater screen, medical examine, entertainments, and commercial application .
