Abstract
A writing and display device for producing luminescent images upon application of pressure thereon which can be readily erased and repeatedly used having a protective layer to prevent damage to the writing surface thereof. The device includes a backing member with a smooth surface over which a translucent or transparent sheet containing a luminescent dye or pigment and an opaque pliable plastic sheet are disposed. At least one of the sheets is formed of a pliable plastic with its interface surface tending to adhere to the interfacing surface of the other sheet when a pressure is applied thereto to produce luminescent images. A pliable, transparent protective sheet is disposed adjacent to and coextensive with the translucent or transparent luminescent sheet. Upon application of pressure onto the protective sheet, which pressure is transmitted to the luminescent sheet by virtue of the pliability of the protective sheet, the interfacing surfaces adhere to each other to thereby produce a luminescent image.
