Abstract
In this paper, several types of conventional stereoscopic projection display systems including the polarization-based, ZScreen-based, LC shutter-based and wavelength multiplex imaging-based have been reviewed and their performances have also been discussed in terms of light efficiency. The results revealed that 55%, 86% and 70% of light loss occurred in the LC shutter-based, ZScreen-based and wavelength multiplex imaging-based stereoscopic projection system, respectively. Meanwhile, in the polarized stereoscopic display system using the Type-1 LCD with the external polarizer, 50% of light loss occurred, whereas in the polarized stereoscopic display system using Type-2 LCD with the half-wave retarder and external polarizer, no light loss occurred. In addition, in the polarized stereoscopic projection system using the Type-1 LCD projector and the quarter-wave retardation film, no light loss also occurred. But in all of these cases, some additional light loss might be expected because of light absorption through the employed optical components. On the other hand, in the polarized stereoscopic projection system using the rotated Type-1 LCD/Type-2 LCD projector and the modified Type-1 LCD projector without the external polarizer, no light loss occurred because no additional optical components for polarization were needed.
