Abstract
1,234,068. Colour televison tubes. SONY CORP. 15 July, 1968 [19 July, 1967], No. 33613/68. Heading H1D. A plural-beam colour television display tube has a delta arrangement of beam cathodes K G , K R , K B and delta arrays of colour phosphors at the screen S, an auxiliary lens L<SP>1</SP> for causing parallel beams derived from the cathodes to intersect a focusing lens L at the point of intersection and a deflecting system F for converging the beams to a common point at the colour selection grid or shadow mask M. The convergence system F has a common inner electrode 11 having angularly related portions P 1 , P 2 , P 3 and an outer set of electrodes QR, Q G , Q B as shown. In another embodiment (Fig. 4) the inner electrode 11 (11<SP>1</SP>) is in the form of a tube of triangular or deltoid cross-section.
