Method of making electroluminescent panels |
March 3, 1987 |
| Flexible, electroluminescent panels or lamps employ a phosphor which is embedded in a coating formulation, in which a polyester laminating resin has been activated by a catalyst containing toluene diisocyanate or diphenylmethane diisocyanate, to provide a relatively high dielectric c |

Power supplies for electroluminescent panels |
June 17, 1986 |
| DC operated power supplies for electroluminescent lamps are self-inhibited from further oscillations and thus are current limited in the event that a failure occurs in an EL lamp which results in the EL lamp being shorted. Single ended and push/pull transformer power supplies are disclos |
