Patent ID: 7440044

Claim:
A color display comprising: a monochromatic light source; an array of pixel elements; a liquid crystal optical switch between the monochromatic light source and the array of pixels elements; a first wavelength selective reflector provided between said monochromatic light source and said array of pixel elements; and a second wavelength selective reflector provided across said array of pixel elements at a position facing said first wavelength selective reflector, wherein at least some of the array of pixels elements include anisotropically emitting photoluminescent material; said first wavelength selective reflector transmits light emanated from said monochromatic light source and reflects light emitted by said anisotropically emitting photoluminescent material; and said second wavelength selective reflector reflects light emanated from said monochromatic light source and transmits the light emitted by said anisotropically emitted photoluminescent material.
