1. An illuminated graphic display apparatus, comprising:
- (a) a booklet apparatus having a centrally located spine member including a hollow inner chamber, a first thin cover member pivotally coupled to said spine member at a first end and a second thin cover member pivotally coupled to said spine member at said other end, to thus form a booklet with at least one of said thin cover members of a sleeve configuration having a slit for insertion therein of a series of planar sheets, said surface of said one cover member having a large aperture for exposing to view one of said sheets when inserted in said cover member,(b) a first planar sheet inserted in said sleeve having located thereon, graphic data to be viewed, said data as positioned on said sheet located within said aperture of said cover member, said graphic data impressed thereon by an electrostatic process,(c) a second planar panel member underlying said first sheet and also inserted in said sleeve, said second planar member comprising an electroluminescent capacitor adapted to emit light when energized for illuminating the graphic data on said first sheet, and(d) energizing means including an oscillator adapted to provide a repetitive waveform when energized by a battery located in said hollow inner chamber of said spine member for energizing said second planar member to thereby cause the same to emit light.

Abstract
A booklike article such as a menu, opera score, sports program, theatre program comprises a first relatively transparent layer having impressed thereon indicia representative of graphic data associated with the typical article. Underlying the transparent layer is an electroluminescent panel which upon application of a suitable operating potential, will emit radiation in the light spectrum, thus enabling the grahic data to be viewed in dark environments. A source of potential is located in the spine of the book. The source is battery operated and supplies an output for energizing the panel.
