  • Publication number: 20040183434
    Abstract: Eletroluminescent elements with doubled-sided luminous surface and feasible processes for making such elements are disclosed. Double-sided illuminating EL lamps comprise a common layer in the preferred multilayer structure are proposed, and the use of common layer in such double-sided illuminating EL lamps have the advantages of fewer layers, smaller thickness, less weights, fewer manufacturing steps and less cost without sacrificing any functional feature or performance. Such double-sided illuminating EL lamps may be fabricated by paste-coating or ink-printing method with a sequential-process or split-process, and these EL lamps provide two illuminating surfaces that can emit light simultaneously or independently depending on the design of EL structure and driver's circuit.

  • Publication number: 20030198040
    Abstract: A luminescent book includes a frame. A luminescent panel, a film switch, a circuit board and a back plate are sequentially mounted on the frame. The circuit board is electrically connected with the luminescent panel and the film switch for providing information in several modes. The luminescent panel includes a plurality of areas each of which is formed with a pattern and can be activated regardless of the other. A speaker is electrically connected with the circuit board. In a first mode, the patterns are highlighted sequentially. When a pattern is highlighted, sound is provided. The process repeats once if the first button is pressed within a period of time after the last pattern is highlighted and ends if otherwise. In a second mode, one of the patterns can be pressed so that it is highlighted before sound representative of the pressed pattern is provided. The process repeats if any of the patterns is pressed within a period of time after the sound is provided and ends if otherwise.
