Abstract

Un dispositif d'affichage tête haute comprend une unité de génération d'image (3) conçue pour émettre un faisceau lumineux, destiné à être projeté en sortie du dispositif d'affichage tête haute en direction d'une lame partiellement transparente, l'unité de génération d'image (3) comportant une source de lumière (20) et un écran (26) de manière à générer le faisceau lumineux. Le dispositif d'affichage tête haute comporte également un filtre de limitation de l'étalement angulaire (28) du faisceau lumineux.A head-up display device comprises an image generation unit (3) designed to emit a light beam, intended to be projected at the output of the head-up display device towards a partially transparent blade, the unit generating an image (3) comprising a light source (20) and a screen (26) so as to generate the light beam. The head-up display device also includes a filter for limiting the angular spreading (28) of the light beam.
