Abstract

Un dispositif d'affichage est divulgué. Le dispositif d'affichage est un dispositif d'affichage qui est fixé à un dispositif de rotation et est mis en rotation par le dispositif de rotation, et comprend une interface de communication, un dispositif d'affichage et un processeur. Lorsqu'une entrée utilisateur pour faire tourner le dispositif d'affichage se trouvant dans une première posture vers une seconde posture est reçue pendant qu'une image est affichée sur le dispositif d'affichage, le processeur transmet une instruction de rotation au dispositif de rotation par l'intermédiaire de l'interface de communication; et lorsque le dispositif d'affichage est mis en rotation d'un angle prédéfini ou plus par le dispositif de rotation qui est commandé selon l'instruction de rotation, le processeur amène le dispositif d'affichage à afficher l'image sur la base de la seconde posture. Pendant que le dispositif d'affichage tourne, si la rotation du dispositif d'affichage est arrêtée en fonction de l'état du dispositif d'affichage et/ou du dispositif de rotation, le processeur identifie l'angle de rotation du dispositif d'affichage correspondant au temps arrêté; et si le dispositif d'affichage est identifié comme pouvant être mis en rotation lorsque l'état d'au moins un dispositif change, le processeur identifie la direction de rotation du dispositif d'affichage sur la base de l'angle de rotation identifié et de la première posture, et transmet l'instruction de rotation pour faire tourner le dispositif d'affichage dans la direction de rotation identifiée au dispositif de rotation par l'intermédiaire de l'interface de communication.
