Abstract
1,241,366. Colour television tubes. SONY CORP. 9 Dec., 1969 [26 Dec., 1968], No. 60130/69. Heading H1D. In a colour television tube of the type wherein three coplanar beams diverge from the centre of a lens L M and are converged on a shadow mask or grill by means of outer and inner deflection plates P1 and P2, an intermediate apertured electrode 12 or 12<SP>1</SP> (Fig. 3) is disposed between each pair of plates and is connected to the inner one to maintain a substantially constant convergence field in spite of variations in the final anode potential which is also applied to the inner plates P2. Preferably, the outer plates P1 are earthed, as shown, to avoid the need of a second H.T. supply voltage, and the electrode 12 then also serves to reduce the field strength to a suitable value. In Fig. 3, the electrode 12 comprises five parallel wires extending transversely of the axis; alternative forms comprise longitudinal wires (Fig. 6A, not shown), a mesh (Fig. 6B, not shown), or a plate provided with large or small apertures (Fig. 6C and 6D, not shown).
