Abstract
(EN)
Provided by embodiments of the present disclosure are a dual-view display method and device and a non-temporary computer readable storage medium. The dual-view display method is used for a dual-view display device comprising a display module (10) and a liquid crystal grating (20), the method comprising: obtaining information of observers (1, 2); adjusting an operation mode of the liquid crystal grating (20) according to the information of the observers (1, 2), thereby adjusting a light output direction and a display mode of the display device; and displaying an image using the display mode according to the information of the observers (1, 2), wherein the operation mode of the liquid crystal grating (20) is adjustable. The present dual-view display method and device may automatically track the position and movement of different observers (1, 2). Regardless of which angle an observer is located at, the screen light may be directly emitted in the direction of the eyes of the observer so as to achieve the best display effect.

La présente invention concerne, selon des modes de réalisation, un procédé et un dispositif d'affichage à double vue et un support d'enregistrement lisible par ordinateur non temporaire. Le procédé d'affichage à double vue est utilisé pour un dispositif d'affichage à double vue comprenant un module d'affichage (10) et un réseau de cristaux liquides (20), le procédé consistant à : obtenir des informations d'observateurs (1, 2) ; ajuster un mode de fonctionnement du réseau de cristaux liquides (20) en fonction des informations des observateurs (1, 2), ce qui permet d'ajuster une direction de sortie de lumière et un mode d'affichage du dispositif d'affichage ; et afficher une image à l'aide du mode d'affichage selon les informations des observateurs (1, 2), le mode de fonctionnement du réseau de cristaux liquides (20) étant réglable. Le présent procédé et le dispositif d'affichage à double vue peuvent suivre automatiquement la position et le mouvement de différents observateurs (1, 2). Quel que soit l'angle où se trouve un observateur, la lumière d'écran peut être directement émise dans la direction des yeux de l'observateur de façon à obtenir le meilleur effet d'affichage.
