Abstract
(EN)
An elevator display system of the present invention comprises: an elevator shaft of which one or more surfaces are transparent, wherein one or more PDLC films are provided on the transparent surfaces; an elevator car of which one or more parts are transparent such that sight is secured in a direction of the transparent surfaces of the elevator shaft, and which comprises a distance measuring sensor in one or more of a top portion and a bottom portion thereof; a projector for projecting an image onto the transparent surfaces of the elevator shaft; and a control module comprising a tracking unit for determining a location (L) of the elevator car from information collected by the distance measuring sensor and a control unit for controlling a voltage applied to the plurality of PDLC films according to the location of the elevator car.
(FR)
L'invention concerne un système d'affichage d'ascenseur qui comprend : une cage d'ascenseur dont une ou plusieurs surfaces sont transparentes, un ou plusieurs films de PDLC étant disposés sur les surfaces transparentes; une cabine d'ascenseur dont une ou plusieurs parties sont transparentes de telle sorte que la vue soit garantie dans une direction des surfaces transparentes de la cage d'ascenseur, et qui comprend un capteur de mesure de distance dans une ou plusieurs parties parmi une partie supérieure et une partie inférieure de celui-ci; un projecteur pour projeter une image sur les surfaces transparentes de la cage d'ascenseur; et un module de commande comprenant une unité de suivi pour déterminer un emplacement (L) de la cabine d'ascenseur à partir d'informations collectées par le capteur de mesure de distance et une unité de commande pour commander une tension appliquée à la pluralité de films de PDLC en fonction de l'emplacement de la cabine d'ascenseur.
