<p>An apparatus and method for displaying back-lighted images to viewers moving along a path of travel past viewing boxes containing transparent images illuminated by substantially vertical light sources of narrow width relative to the transparent images, the light sources being located behind the transparent images, relative to the viewer. The light source can be a series of LEDs or fluorescent or neon tubes, and a vertical slit can be used to reduce the width of their output. The back-lighted images can have the appearance of either a still image or produce the effect of moving images and the transparent images can be displayed on a video display remotely updatable by an update signal which may be wireless or wired generated based upon a preselected criterion such as time or detection of movement and the update signal can cause the transparent images to change to different images so that different viewers moving past the viewing box at different times see different images. Viewing boxes can have multiple images and vertical light sources. Transparent images can be displayed on video displays so they can be individually adjusted remotely vertically and horizontally to make images register, image to image, and the transparent video display image can be adjusted in its width to compensate for changes in speed of viewers moving along the path of travel past the display.</p> |
