Abstract
A polarizing fiber-optic layer for use within a liquid crystal multilayer structure, particularly for use in a computer system having a liquid crystal display screen. The invention relates to a specially designed thin polarizing fiber-optic layer which functions both as a polarizer of light in a specific direction and as a fiber-optic material for optically resolving an image to its surface from a position optically below the fiber-optic material layer. Using this double functioning material the problems of off axis viewing, contrast (and color) distortion and parallax can be solved in flat panel displays. This inventive layer replaces several complex layers of a conventional liquid crystal display thereby greatly simplifying display manufacture and improving performance.
