<p>A display system which includes a source of polarized light (30), an analyzer (22) for reflecting or transmitting light as a function of wavelength and polarization, and a display (63) which changes the polarization of the light from the analyzer and then directs the light to the analyzer for reflection or transmission. A method of display including providing polarized light, analyzing by reflection and transmission in accordance with polarization and wavelength, generating a pattern by changing the polarization of light from the analyzer, then analyzing the light with the analyzer. A reflective variable birefringence liquid crystal cell with an active matrix substrate, liquid crystal at one substrate having homeotropic alignment and a state with minimal phase retardation at the other substrate. A display including a light modulator and light source, and a control for the intensity of light from the source. A method of displaying an image using passive light modulation including controlling the intensity of a light source as a function of the brightness of the image to be displayed.</p> |
