IMAGE-COMBINING DEVICE AND PROJECTION DISPLAY APPARATUS HAVING IMAGE-COMBINING DEVICES INCORPORATED THEREIN

摘要

An image-combining device comprising of a polarizing beam-splitter, two waveplates and two reflective micro-electro-mechanical display panels is described. It combines images with orthogonally polarized light. Projection display apparatus having such image-combining device(s) are used to project two-dimensional or three-dimensional images with orthogonally polarized light.
