Patent ID: 7113324

Claim:
An image display apparatus, comprising: a light source for providing a light beam; a spatial light modulator configured to selectively modulate said light beam along a first path to form a first path light beam or along a second path to form a second path light beam; a total internal reflection (TIR) prism, disposed between said light source and said spatial light modulator, for said light beam to pass therethrough in a first direction before being incident on said spatial light modulator; a projection lens set, disposed between said spatial light modulator and a screen, for projecting said first path light beam on said screen to form a first image; and a reflector for reflecting said second path light beam to form a reflected light beam, wherein said reflected light beam is incident onto said TIR prism in a second direction and reflected, as a recaptured light beam, onto said spatial light modulator in said first direction.
