First Claim
Patent Images
1. A scroll type display device comprising:
- a frame;
a pair of spools supported on the frame and spaced apart from one another;
a flexible web having graphics thereon and being entrained about the pair of spools to span therebetween for scrolling of said flexible web between said first pair of spools under rotation of at least one of said pair of spools;
a drive mechanism operable to drive rotation of said at least one of said pair of spools;
an illumination panel supported on the frame to underlie the span of the flexible web between the pair of spools, the illumination panel comprising a plurality of multi-color light sources each operable to emit different colors of light to change an illuminated state of the illumination panel;
a control system operable to control the multi-color light sources and the drive mechanism, the control mechanism being configured such that scrolling of flexible web from one position to another to change a display shown at the span of the flexible web between the spools corresponds to a respective automatic change in the illuminated state of the illumination panel.

Abstract
A unique scrolling backlit display used for advertising or the like features two sets of spools carrying separate webs thereon that respectively contain background and foreground imagery, whereby scrolling of one web relative the other increases the number of distinct visuals that can be attained with the device, and also allows dynamic animation-like displays in which foreground images change over a maintained background, or vice-versa. Multi-color LED light sources in the backlighting device are operable to create vibrant, dynamic lighting effects, while illumination of the display housing further increases the visual appeal of the display.

12. A scroll type display device comprising:
-
a frame; a pair of spools supported on the frame and spaced apart from one another; a flexible web having graphics thereon and being entrained about the pair of spools to span therebetween for scrolling of said flexible web between said first pair of spools under rotation of at least one of said pair of spools; a drive mechanism operable to drive rotation of said at least one of said pair of spools; an illumination panel supported on the frame to underlie the span of the flexible web between the pair of spools, the illumination panel comprising a plurality of multi-color light sources distributed at different positions to illuminate different portions of said illumination panel; and an illumination controller operable to vary an illumination pattern of the illumination panel by switching a color of light at one or more said different positions; and a drive controller linked to the illumination controller and operable to control the drive mechanism; wherein the controllers are arranged so that scrolling of flexible web from one position to another to change a display shown at the span of the flexible web between the spools corresponds to a respective automatic change of the illumination pattern of the illumination panel.
