The present invention discloses an electroluminescent panel device in which a laminate having an electroluminescent layer held between an opposed electrode and a transparent electrode is sealed by a pair of protective sheets, wherein a metal composite film having a metal foil rigidly held by a resin film is used as the protective sheet on the side of the opposed electrode, first and second terminals are drawn from the transparent electrode and the opposed electrode, the first terminal and the metal foil held on the resin film being connected in conduction, and an AC drive electric field is applied to the first and second terminals to thereby suppress vibrations of the electroluminescent panel caused by application of the drive electric field.

Method for manufacturing a vibration suppressing electroluminescent

A lead wire mounting structure for an electroluminescence including a first retainer plate having a plurality of bosses some of which are to be inserted through sealing films of the electroluminescence, and a second retainer plate having a plurality of holes to be engaged with the bosses, wherein the first and second retainer plates are opposed to each other in such a manner as to sandwich marginal end portions of the sealing films, the terminals projecting from the sealing films, and end portions of the insulated lead wires fixedly connected to the terminals, and the bosses of the first retainer plate inserted into the holes of the retainer plate are caulked to firmly hold the marginal end portions of the sealing films and the end portions of the insulated lead wires.

Lead wire mounting structure for electroluminescence

An electroluminescence device having an excellent moisture-resistant property is disclosed. Such an electroluminescence device comprises a light emitting layer inserted between an opposite electrode and a transparent electrode to form a multi-layered structure, said structure being airtightly sealed by a pair of protective sheets and said ELD being able to be fitted to an external apparatus by means of a metal fixture. The ELD is characterized in that a metal composite film is formed by inserting a metal foil between a pair of resin films and is used for one of the protective sheets for said opposite electrode. The composite film having a notch which is formed by removing part of the metal foil around a portion of the metal composite film prepared to accommodate the metal fixture.

Encapsulated electroluminescence device

An electronic tuning block including a plurality of screw drive type variable resistors are juxtaposed parallel to one another obliquely on an insulating substrate, and holes for receiving pointers fitted to the screws of the variable resistors and holes for receiving rotary knobs fitted to the tips of the screw shaft are formed on the upper surface of a box-shaped insulating case which is fixed to the insulating substrate.
