Method of manufacturing an optical element, optical element and display device

摘要

An optical element, notably an optical element for creating a retractable sheet for use in a motor vehicle, has in the final state a three-dimensional shape resulting from forming of the optical element, the optical element being designed to have an extended shape comprising: a first main surface, a second main surface, and an edge surface. A method of manufacturing involves during a first step of the method, forming the optical element to give its final three-dimensional shape in terms of the first main surface, the second main surface and the edge surface. During a second step at least one of the surfaces of the optical element is cleaned. During a third step, a functional coating is applied to the first main surface and/or the second main surface.

主权项

1. A method of manufacturing an optical element for creating a retractable sheet for use in a motor vehicle, the optical element having an expansive shape, and the optical element comprising:
a first main surface corresponding to the expansive shape; a second main surface opposed to the first main surface; and an edge surface connecting the first main surface and the second main surface and including a convex shape that curves toward the first main surface, the second main surface, or a combination thereof; the method of manufacturing the optical element comprising: forming the optical element to give the optical element a three-dimensional shape provide by the first main surface, the second main surface, and the edge surface; cleaning at least one of the first main surface, the second main surface, and the edge surface; and applying a functional coating to the first main surface and/or the second main surface; wherein the optical element has the three-dimensional shape in a final state of the optical element.
