Abstract

L'invention concerne un affichage tête haute comprenant une unité de source lumineuse équipée d'une source lumineuse qui projette de la lumière pour former des images virtuelles, une unité d'affichage présentant un élément optique sur lequel est projeté la lumière provenant de la source lumineuse, et un élément de connexion qui connecte l'unité de source lumineuse et l'unité d'affichage. L'unité de source lumineuse et l'unité d'affichage sont connectées par l'élément de connexion, et la lumière émise par la source lumineuse est projetée sur l'élément optique de l'unité d'affichage. Une unité de suppression formée sur au moins une partie de l'élément de connexion réduit au minimum le blocage de la zone de trajectoire lumineuse formée entre l'unité de source lumineuse et l'unité d'affichage, par la lumière provenant de la source lumineuse, en raison de l'endroit du corps mobile où est attaché l'élément tête haute. Par conséquent, lorsque l'affichage tête haute est attaché au corps mobile, cela permet d'éviter que la lumière provenant de la source lumineuse soit bloquée par ledit endroit du corps mobile où est attaché l'élément tête haute, et qu'une partie de l'image à afficher ne manque.
