Abstract
445,978. Television receivers. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and DUDDING, B. P., c/o General Electric Co., Ltd., Wembley, Middlesex. March 26, 1935, No. 9385. [Class 40 (iii)] A coloured luminous area 1 is produced round the screen 2 of a cathode-ray tube 3 to reduce the apparent colour of the image on the screen. The colour of the area is similar, for example yellow, rather than complementary, to the red or orange colour of the image. The surface round the screen is coloured, and the source, which may be the general illumination, illuminating the surface is not highly coloured. Specification 392,869 is referred to.
