Abstract

The invention discloses an optical lens, and aims to solve the problem of inconvenience in processing large screens with an existing optical lens. The optical lens comprises a first glass window, a second glass window, a first optical waveguide array and a second optical waveguide array, wherein the first optical waveguide array and the second optical waveguide array include at least one optical waveguide array respectively; each optical waveguide array unit comprises at least one obliquely-arranged optical waveguide; and the upper and lower surfaces of the optical waveguides are provided withreflecting layers, and the waveguide directions of corresponding parts in the first and second optical waveguide arrays are perpendicular to each other. By splicing the optical waveguides with the optical waveguide array units and splicing the optical waveguide array units with the first and second optical waveguide arrays, the processing of large screens is skillfully converted into splicing ofvarious types of optical waveguides, thereby lowering the manufacturing difficulty to a certain extent and improving the processing efficiency.

Description

technical field [0001] The present invention relates to the field of optics, in particular, the present invention relates to an optical lens. Background technique [0002] With the development of imaging display technology, the requirements for imaging characteristics are constantly improving. A higher resolution is required to ensure the clarity of the observed picture while meeting the requirement of small distortion. Existing imaging technologies mainly use spherical, aspheric, Fresnel and other lenses for imaging. Limited by the field of view and aperture, there are optical aberrations such as spherical aberration, coma, astigmatism, field curvature, distortion, and chromatic aberration. [0003] see figure 1 , part of the solution, such as the Chinese invention patent application number 201480005418.X, discloses a method for manufacturing a light control panel with light reflection parts arranged in parallel. The technical scheme of the control panel and the optical ...
