ABSTRACT:
A projection display apparatus, including an illumination system, a light integrator, a first mirror module, a second mirror module, a beam condensing module, a total internal reflection (TIR) prism, a light modulator, and a set of projection lenses. The illumination system generates an optical beam propagating along a first beam path in a first direction. The first and second mirror module folds the optical beam, which is imaged onto the light modulator. The modulator selectively reflects the optical beam so as to propagate along a fourth beam path in a fourth direction, where the first beam path and the fourth beam path are substantially perpendicular with respect to each other. The invention provides a compact projection system for easy carriage.
