Embodiment Construction

[0055] as attached Figures 1 to 5 As shown, the optical element 1 can be produced in a simple and efficient manner using the production method according to the invention.

[0056] The optical element 1 is used, for example, as an optical element for making retractable panels for use in motor vehicles. Such optical elements are used in particular in motor vehicles having a display device comprising a projection module for generating an image for the purpose of projecting the image in a normal direction of gaze of a user of the display device.

[0057] Typically, the optical element has an elongated shape including:

[0058] - the first main surface,

[0059] - the second major surface, and

[0060] - an edge surface of the optical element.

[0061] According to the manufacturing method of the present invention, the optical element 1 has a three-dimensional shape resulting from the step of forming the optical element 1 obtained using a method comprising the following steps:...

Abstract

The invention relates to a method of manufacturing an optical element (1), notably an optical element for creating a retractable sheet for use in a motor vehicle. The optical element has in the final state a three-dimensional shape that is the result of a step of forming of the optical element. The optical element being designed to have an extended shape comprises: -a first main surface, -a second main surface, and -an edge surface of the optical element. The method of manufacturing the optical element involving the following steps: -during a first step of the method, the optical element is formed to give the optical element its final three-dimensional shape in terms of the first main surface, the second main surface and the edge surface of the optical element, -during a second step of the method, at least one of the surfaces of the optical element is cleaned, -during a third step of the method, a functional coating is applied to the first main surface and / or the second main surface.

Description

technical field [0001] The invention relates to a method of manufacturing optical elements, in particular optical elements for the manufacture of retractable panels for use in motor vehicles. The invention also relates to an optical element, in particular for making a retractable panel for use in a motor vehicle, and also to a display device, in particular for a motor vehicle. Background technique [0002] Display devices which utilize the principle of a head-up display have been in daily use in the field of motor vehicles for several years now. [0003] Head-up displays allow information to be projected into the field of view when looking into the space in front of the motor vehicle so that the driver of the motor vehicle can read the information without removing his eyes from the space in front of the motor vehicle. At the same time, the driver of the motor vehicle is able to read the information without having to adjust his eyes. [0004] Certain display devices utilize...
