A cross-sectional shape of each annular protrusion along a cross section perpendicular to the plane is a triangular shape or a multi-step shape or a free surface shape. The width of one side of each cross-sectional shape parallel to the plane gradually changes, and gradual change of the cross-sectional shape and the width thereof determines light gathering characteristics of the spherical Fresnel lens layer or the aspherical Fresnel lens layer. A surface of each annular protrusion has scattered microstructures.Type: ApplicationFiled: January 18, 2022Publication date: February 29, 2024Applicants: IVTECH JIANGSU CO., LTD., IVTOUCH CO., LTD., SVG TECH GROUP CO., LTD.Inventors: Xiaohong ZHOU, Ming ZHU, Donglin PU, Pengfei ZHU, Haoshu ZHU, Rubin SUN, Linsen Chen
