A LENS SHEET FOR 3-DIMENSIONAL IMAGE HAVING COLOR

摘要

PURPOSE: A stereoscopic lens sheet for color expressions is provided to manufacture a lens sheet by a diamond tool and make a lens invisible in a surface, thereby acquiring stereoscopic effects of a lenticular lens and micro lens at the same time. CONSTITUTION: A stereoscopic lens sheet(300) for color expressions includes a first lenticular lens layer(310), a refraction control bonding layer(320), a second lenticular lens layer(330), a focal distance layer(340), and a stereoscopic layer(350). The first lenticular lens layer arranges a plurality of semi-circumferential convex lenses in parallel. The refraction control bonding layer is arranged in the lower part of the first lenticular lens layer. The second lenticular lens layer is arranged in the lower part of the refraction control bonding layer. The semi-circumferential convex lens is arranged in the second lenticular lens layer in parallel. The focal distance layer is arranged in the lower part of the second lenticular lens layer. The stereoscopic layer is arranged in the lower part of the focal distance layer. The first lenticular lens layer and second lenticular lens layer cross a bus line of the semi-circumferential convex lens arranged in the first lenticular lens layer and a bus line of a semi-circumferential convex lenses arranged in the second lenticular lens layer from each other. The first lenticular lens layer and second lenticular lens layer make lenticular curvature to face each other.
