Abstract

1,260,079. Colour television tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 20 Oct., 1970 [23 Oct., 1969], No. 49699/70. Heading H1D. In a colour television tube of the shadow mask type with a screen comprising discrete luminescent areas, e.g. dots, separated by light absorbent areas and coated with a reflecting metal layer, the metal layer is coated with a heat-absorbent layer of graphite so that heat from the shadow mask may be dissipated via the faceplate of the tube.
