Abstract

733,353. Electroluminescence. BRITISH THOMSON-HOUSTON CO., Ltd. March 30, 1953 [April 9, 1952], No. 9084/52. Drawings to Specification. Class 39 (1). The electroluminescent phosphor of an illuminating device is separated from the conductive coatings at least on one face, by a film of cellulose acetate or polystyrene. The insulating material is fixed with a thermoplastic adhesive and the conducting layers may have protective sheets or supporting members. The phosphor is applied as a suspension in a binder which may be a glyptal resin or a polystyrene compound. Specifications 632,256, [Group XXIII], and 731,677 are referred to.
