Abstract
897,983. Colour television tubes. MULLARD Ltd. Aug. 5, 1960 [Nov. 16, 1959], No. 38769/59. Class 39(1). [Also in Group XL(b)] In a beam-indexing colour-display cathoderay tube, the screen comprises a multi-line colour phosphor layer S, Fig. 2, the phosphors R, G, B being shown separated by guardbands, and two sets of interleaving indexing strips U, V disposed on opposite sides of the blocking layer A and emitting ultra-violet radiation in opposite directions to photo-cells disposed to the front and to the rear of the tube (see Group XL(b)). The backing layer which is opaque to ultra-violet radiation may be the usual aluminium layer. A third set of indexing strips may be added, but in this case optical filters must be used to distinguish the radiation from this set from the radiation from one of the first two sets by indexing strips disposed on the same side of the backing layer. The outer indexing strips U may be combined with one of the phosphor display strips, e.g. the blue. Specification 897,982 is referred to.
