A display system for direct viewing or projection includes a source of polarized light, an analyzer for reflecting or transmitting light as a function of the wavelength and polarization characteristic of incident light, and a display receiving light from said analyzer, the display being operable selectively to change a polarization characteristic of incident light, and light from the display being directed to the analyzer for reflection or transmission thereby. A method of display includes providing a source of polarized light, analyzing polarized light by selectively reflecting or transmitting light as a function of the wavelength and polarization characteristic of incident light, and creating a desired light pattern from light received from said analyzing step by selectively changing a polarization characteristic of incident light, and selectively transmitting light according to such pattern. |
