Abstract

A 2D/3D switchable auto-stereoscopic display with spatial and sequential hybrid control (SSHC) using polymer dispersed liquid crystal (PDLC) films is studied. The light propagation in the SSHC system is simulated with a Monte Carlo ray-tracing method. Relationship between the 2D uniformity and anisotropy factor as well as mean free path is obtained by a series of simulation cases. The uniformity reaches over 85% in simulation. As well, a two-viewpoint prototype is built to give the experimental result. Measurements show that a highly transparent PDLC film can maintain the high-quality 3D performance while a strongly diffusive one can enhance the uniformity in 2D mode. By increasing the driving duty cycle of the backlight units, the issue of luminance attenuation in 2D mode can be addressed. Our technique offers a practical solution for 2D/3D switch in auto-stereoscopic displays.
