Abstract
In a system and method of image display, an image projector is positioned to back project (or rear project) an image on one or more platform doors disposed between a passenger platform of a train or people mover station and a pathway of the train or people mover. The image projector is positioned on the pathway side of the one or more platform doors. The image projector back projects the image on the one or more platform doors such that the image is diffusedly transmitted through them for observation by passengers on the platform side of the station. The back projected image is oriented such that characters or words in the image have a proper left-to-right, or right-to-left, orientation for reading by passengers on the platform side of the station.
Claims26
A method of image display on one or more platform doors of a passenger platform of a train or people mover station, the method comprising:
- (a) providing an image projector positioned to project a first image on one or more platform doors disposed between a passenger platform of a train or people mover station and a pathway of the train or people mover, wherein the image projector is positioned on the pathway side of the one or more platform doors;
- and
- (b) causing the image projector to back project the first image on the one or more platform doors.
A method of image display on a platform door that separates a passenger platform of a train or people mover station from a pathway of the train or people mover, the method comprising:
- (a) positioning an image projector to project an image toward a platform door disposed between a passenger platform of a train or people mover station and a pathway of the train or people mover, wherein the image projector is positioned on the pathway side of the platform door;
- (b) coupling to the image projector a controller that is programmed to cause the image projector to back project the image toward the platform door;
- and
- (c) providing an input to the controller which is responsive to a signal produced via the input for executing the program to cause the image projector to back project the image toward the platform door.
An image display system comprising, in combination:
- a platform door separating a passenger platform of a train or people mover station from a pathway of the train or people mover;
- an image projector positioned on the pathway side of the platform door to project an image toward the platform door;
- and
- a controller programmed to cause the image projector to back project the image toward the platform door.
