Abstract

1392108 Colour television tubes HITACHI Ltd 8 Nov 1972 [8 Nov 1971] 51475/72 Heading H1D In a post-deflection focusing colour television tube a colour selection electrode 6 is supported by a member 7 through insulators 8 and the member 7 is held at a higher potential than electrode 6 to collect secondary and reflected electrons. A shield 15 can be connected to or insulated from member 7.
