Abstract

810,110. Luminescent screens. GENERAL ELECTRIC CO. Ltd. Nov 12, 1957 [Nov. 15, 1956], No. 34941/56. Class 39(1). The luminescent elements of a cathode ray tube screen, e.g. the multidots 9, 10, 11 in different colour phosphors of a tube with a shadow mask 4 are separated by elements 12 adapted to reflect substantially no light, e.g. of graphite. The graphite may be deposited by the same conventional methods as utilized to apply the colour phosphors.
