ABSTRACT:
An image display apparatus is capable of recycling the “OFF” state light to increase the image brightness and contrast. The image display apparatus includes a light source, a spatial light modulator, a total internal reflection (TIR) prism, a projection lens set, and a reflector. The spatial light modulator selectively modulates a light beam from the light source to a first path to form a first path light beam or to a second path to form a second path light beam. The TIR prism disposed between the light source and the spatial light modulator is configured to allow the light beam to travel therethrough in a first direction and to be incident on the spatial light modulator. The projection lens set disposed between the modulator and a screen is configured to project the first path light beam to form an image on a screen. The reflector is configured to reflect the second path light beam to form a reflected light beam that is incident on the TIR prism in a second direction as a recaptured light beam. The recaptured light beam is then incident on the spatial light modulator in the first direction.
