See-through multi-view 3D display with parallax barrier

摘要

In this paper, we propose the see-through parallax barrier type multi-view display with transparent liquid crystal display (LCD). The transparency of LCD is realized by detaching the backlight unit. The number of views in the proposed system is minimized to enlarge the aperture size of parallax barrier, which determines the transparency. For compensating the shortness of the number of viewpoints, eye tracking method is applied to provide large number of views and vertical parallax. Through experiments, a prototype of see-through autostereoscopic 3D display with parallax barrier is implemented, and the system parameters of transmittance, crosstalk, and barrier structure perception are analyzed.
