Abstract
863,067. Colour television. RADIO CORPORATION OF AMERICA. May 2, 1957 [May 16, 1956], No. 14101/57. Class 39(1). In a three-gun cathode-ray tube having a curved aperture shadow mask 19 with a convex surface spaced from the concave target surface of an electron-sensitive screen 17, the spacing between the convex and concave surfaces is less at the outer marginal portions of the surfaces (q) than at their centre (q), in order to minimise degrouping errors resulting from the enlargement and contraction of the electron triangle when triangularly arranged beams are subjected to dynamic convergence forces during their scanning movement. Specification 863,068 is referred to.
