Abstract
An interactive display is disclosed which comprises a housing to receive an induced field activated display sheet which has a plurality of image producing elements responsive to an induced field. The housing has a transparent cover panel and a base panel. The cover panel and the base panel of the display housing comprise a plurality of means for creating a plurality of induced fields for selectively activating the image producing elements of the induced field activated display sheet. By selectively activating the induced field means, selective image producing elements of the induced field activated display sheet will be activated to produce a desired image on the induced field activated display sheet thereby creating a display. If desired the induced field activated display sheet can be removed from the display housing to be used as a printed document.
