Abstract

1,208,780. Colour television tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 29 Nov., 1967 [2 Dec., 1966], No. 54357/67. Heading H1D. In a colour television tube using a colour selection electrode and a number of electron beams which lie substantially in one plane at each point along their length so that dynamic convergence is not required, the neck of the tube accommodating the electron gun or guns follows their general outline. When there are three electron guns disposed side-by-side the neck is of flattened oval shape, which is smaller than the usual round neck and allows deflection coils to be placed closer to each other.
