ABSTRACT:
A cathode ray tube in which a glass-enamel layer having particles with a secondary electron emission coefficient smaller than 1, for example Cr.sub.2 O.sub.3 particles, is provided in the neck.
The percentage of particles exceeds approximately 30% and the surface resistance ranges between 10.sup.10 and 10.sup.14 .OMEGA./.quadrature.. The high-voltage behaviour of such a layer is satisfactory. The convergence drift is relatively small. In addition, a description is given of a method of providing such a glass-enamel layer.
