METHOD OF MAKING A LIGHTGUIDE

摘要

A method of making a Iightguide, comprising the steps of (a) providing a Iightguide film having upper and lower surfaces allowing substantial total internal reflection of light therebetween; (b) applying a viscous and curable material at least to the lower surface in a pattern; (c) applying a surface texture to the material; and (d) curing the material, the resulting surface textured pattern on the base of the Iightguide being capable of extracting light from the Iightguide is disclosed.
