Title
(EN) ELEVATOR DISPLAY SYSTEM
(KO) 엘리베이터 디스플레이 시스템
Abstract
(EN)
Provided is an elevator display system, which includes: an elevator shaft having one or more transparent surfaces and one or more PDLC films on the transparent surface; an elevator car which is transparent to at least a part of the area and secures a distance measurement sensor to at least one of upper and lower portions so as to secure a clear field direction of the elevator shaft; a projector scanning an image on the transparent surface of the elevator shaft; and a control module comprising a tracking unit determining a location (L) of the elevator car from the information collected by the distance measurement sensor and a control unit controlling a voltage applied to the plurality of PDLC films in accordance with the location of the elevator car.
