<p>A reflection type projector includes a critical angle prism 150 for changing the path of light, a light source 110 for generating and emitting light, an image generation unit 160 having a multiplicity of pixels in a two-dimensional array structure, each of the pixels being independently driven, for forming and reflecting an image from the input light, the critical angle prism 150 having a transmission/ reflection surface (151, Fig 4) disposed along an optical path of the light, to transmit the light input from the light source 110 and reflect light re-enter from the image generation unit 160, and a projection lens unit 170 for enlarging and transmitting the light reflected from the transmission/reflection surface of the critical angle prism onto a screen. Colour wheel 120, light mixing unit 130, relay lens unit 140, polariser 161 and analyser 165 are shown. Unit 160 may be a ferroelectric liquid crystal display.</p> |
