Patent attributes
There is disclosed a backlit display structure with multiple LED's arranged to transmit light into a light guide plate configured to uniformly illuminate the back of a readily replaceable translucent image sheet. The display may be incorporated with a decorative frame which also may be illuminated by the same or different LED's. The display powered by a rechargeable battery pack may also be incorporated in table top boxes for condiments, straws, napkins or other conveniences for restaurant customers where it is useful for displaying replaceable advertising or current featured menu items. In another form the guide plate does not uniformly illuminate an image sheet but only illuminates temporary marks thereon from a crayon or marker, thereby providing an illuminated blackboard.
