OPTICAL SHEET FOR GENERATING STEREO SCOPIC IMAGES

摘要

An optical sheet for generating a three-dimensional stereoscopic image is provided to enhance the resolution of the three-dimensional stereoscopic image by arranging lenses having hemispherical sections. An optical sheet includes a plurality of lenses. The lenses are arranged regularly on a plane of a transparent substrate for optical sheet. The lenses correspond to two pixels of a display panel. A sectional surface of each of the lenses has a hemispherical shape. A pitch of each of the lenses is 50 um to 2mm. A radius of curvature of each of the lens is 300 um to 65mm. A refractive index of the lens is 1.35 to 1.65. Each of the lenses has a concave shape or a convex shape. Each of the lenses is a lenticular lens(50) or a micro-lens having a semicylinder shape.
