Scrolling Backlit Display with Superimposed Background & Foregoing Graphics, Multi-Color LED Backlit Panel, and Illuminated Housing

摘要

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.

主权项

1. A scroll type display device comprising:
a frame; a first pair of spools supported on the frame and spaced apart from one another; a second pair of spools supported on the frame and spaced apart from one another; a flexible background web having background graphics thereon and being entrained about the first pair of spools to span therebetween for scrolling of said flexible background web between said first pair of spools under rotation of at least one of said first pair of spools; a flexible foreground web having foreground graphics thereon and being entrained about the second pair of spools for scrolling of said flexible foreground web between said second pair of spools in a position overlying the span of the flexible background web between the first pair of spools under rotation of at least one of said second pair of spools; a first drive mechanism operable to drive rotation of said at least one of said first pair of spools; a second drive mechanism operable to drive rotation of said at least one of said second pair of spools; and a backlight device supported on the frame to underlie the span of the flexible background web between the first pair of spools on a side of said flexible background web opposite the flexible foreground web.
