Title (EN) IMAGE GENERATING DEVICE, HEAD-UP DISPLAY COMPRISING SUCH A DEVICE AND METHOD FOR MANUFACTURING AN IMAGE GENERATING DEVICE
(FR) DISPOSITIF DE GÉNÉRATION D'IMAGE, AFFICHEUR TÊTE HAUTE COMPRENANT UN TEL DISPOSITIF ET PROCÉDÉ DE FABRICATION D'UN DISPOSITIF DE GÉNÉRATION D'IMAGE
Abstract:
(EN) An image generating device comprises a light source producing a light beam and a screen (5) traversed by the light beam and designed to modify the light beam so as to form an image. The screen (5) comprises a transparent element (150) traversed by the light beam and designed to evacuate the heat generated at the level of the screen (5). Said transparent element (150) is made of sintered transparent ceramic. Also described are a head-up display comprising such a device, and a method for manufacturing an image generating device.
(FR) Un dispositif de génération d'image comprend une source de lumière produisant un faisceau lumineux et un écran (5) traversé par le faisceau lumineux et conçu pour modifier le faisceau lumineux de manière à former une image. L'écran (5) comprend un élément transparent (150) traversé par le faisceau lumineux et agencé pour évacuer la chaleur générée au niveau de l'écran (5). Ledit élément transparent (150) est réalisé en céramique transparente frittée. Sont également décrits un afficheur tête haute comprenant un tel dispositif, et un procédé de fabrication d'un dispositif de génération d'image.
