Abstract
A grating lens is disclosed. The grating lens is of a uniform columnar body, both shapes and sizes of respective cross sections perpendicular to an axis of the grating lens are the same, the grating lens includes sides formed of a plane and a cambered surface, an intersecting line between an oblique section of the grating lens and the cambered surface is a circular arc, and the oblique section is any section which forms a predetermined angle A with the axis of the grating lens and is perpendicular to the plane, where 0°<A<90°. The present invention also discloses a lens-type grating and a display device which include the above grating lens.
Claims19
A grating lens consisting of one plane, one cambered surface, and two bottoms at both ends of the grating lens, an axis of the grating lens being a line connecting centers of the two bottoms, wherein the grating lens is of a uniform columnar body, shapes and sizes of respective cross sections perpendicular to the axis are uniform, respectively, the grating lens includes sides formed of the plane and the cambered surface, an intersecting line between an oblique section of the grating lens and the cambered surface is a circular arc, and the oblique section is any section which forms a predetermined angle A with the axis of the grating lens and is perpendicular to the plane, wherein the predetermined angle A ranges from 70° to 85°, and
