<p>748,683. Electroluminescence. BRITISH THOMSON-HOUSTON CO., Ltd. April 6, 1954 [April 8, 1953], No. 10095/54. Drawings to Specification. Class 39 (1). One of the electrodes of a flexible electroluminescent panel is a light-transmitting flexible material formed of conductive glass fibres. The other electrode may be of the same material or a sheet of metal or metallized or metal-clad plastic or plywood. The phosphor, e.g. zinc oxide-zinc sulphide activated by copper, manganese, lead or silver may be dispersed in a solid dielectric which cements it to the glass fibres and a covering layer and edge mouldings of transparent plastic cover the assembly except where metal terminal tabs are applied. The conductive glass is made by drawing glass fibres at 600‹ C. through an atmosphere of anhydrous stannic tetrachloride; or by spraying cadmium nitrate or indium trichloride solution in atomized form onto the fibres. The fibres are spun and woven into cloth or pressed to form paper sheets. Glass paper or cloth may alternatively be rendered conductive by dipping in a solution of a metal salt, e.g. indium tri-fluoro-acetate with stannic chloride dissolved in ethylene glycol mono-ethyl-ether acetate. Specification 748,684, [Group III], is referred to.</p> |
