Abstract
The present invention teaches a liquid crystal display system comprising a liquid crystal display ("LCD") having a plurality of pixels. Moreover the system comprises an illuminator for illuminating each of said plurality of pixels. The illuminator comprises an optical fiber for transmitting a light beam within said fiber, and a number of discrete scattering sites positioned along the fiber for scattering a portion of the light beam outside said fiber. The number of discrete scattering sites are optically coupled with the plurality of pixels such that the plurality of pixels are illuminated by the light beam scattered outside the fiber through the number of discrete scattering sites.
