Abstract

In this paper, a new LCD polarized stereoscopic projection method with improved light efficiency is suggested. In the proposed system, two external polarizers are taken away from the conventional LCD polarized stereoscopic projection system by effectively taking into account of inherent polarization properties of the LCD projectors, so that light efficiency of the proposed system can be dramatically improved. From some experimental results with the Type-1 LCD projectors of NEC MT 1060R, it is found that the proposed system shows zero light loss in the polarization process and the resultant stereoscopic image projected from this system is 213%, 75% and 300% brighter than those projected from the conventional Type-1 LCD projector-based, Type-2 LCD projector-based and Type-3 projector-based systems, respectively.
