Abstract

L'invention concerne un appareil d'affichage comprenant un dispositif de source de lumière comprenant un élément de source de lumière et conçu pour émettre une lumière laser émise en sortie lorsque l'élément de source de lumière est alimenté en courant et allumé, un dispositif de balayage conçu pour afficher une image avec une lumière de balayage constituant la lumière laser balayée en deux dimensions, et un photodétecteur conçu pour recevoir la lumière de balayage. L'appareil d'affichage effectue une commande temporelle dans laquelle l'intensité de la lumière reçue par le photodétecteur est commandée en fonction d'une période pendant laquelle l'élément de source de lumière est allumé dans un état dans lequel une quantité prédéterminée de courant est fournie à l'élément de source de lumière, la période lorsque le photodétecteur est balayé différant en fonction de l'intensité de la lumière.
