Abstract

La présente invention concerne un procédé et un appareil de commande d'affichage pour un écran d'affichage holographique 3D, ainsi qu'un support de stockage. Le procédé comprend les étapes suivantes : au moyen d'un premier capteur et d'un second capteur qui sont disposés au niveau d'un ventilateur holographique 3D, détecter en temps réel des informations de lumière d'un environnement dans lequel un écran d'affichage holographique 3D est situé, et détecter s'il y a un individu dans un rayon prédéfini, et lorsqu'il y a un individu dans le rayon prédéfini, un processeur commande l'activation du ventilateur holographique 3D ; et dans un état de fonctionnement de l'écran d'affichage holographique 3D, le processeur génère des premières informations de commande en fonction des informations de lumière, et il se base sur les premières informations de commande pour commander le ventilateur holographique 3D afin d'ajuster la luminosité de l'écran d'affichage holographique 3D. Dans les modes de réalisation de la présente invention, deux types de capteurs déterminent en temps réel si la luminosité d'un écran d'affichage holographique 3D qui est dans un état de fonctionnement doit être ajustée en fonction de la lumière dans l'environnement dans lequel l'écran d'affichage holographique 3D est situé, et un ventilateur holographique 3D est activé au moment opportun uniquement lorsqu'il est détecté qu'un individu regarde l'écran d'affichage holographique 3D, de telle sorte que l'écran d'affichage holographique 3D produit un affichage de façon normale. Grâce à cela, l'objectif d'une économie raisonnable d'énergie pendant l'utilisation de l'écran d'affichage holographique 3D est atteint.
