摘要

A television or other display system comprises an optical system arranged to project an enlarged image of a picture tube or the equivalent onto an image screen comprising a light-transmitting screen incorporating an array of microlenses. The light transmitting screen is a layer of photopolymer in which an array of graded refractive index microlenses has been formed by selective exposure of a corresponding monomer layer to ultraviolet light, for example through an appropriate mask.
