Cathode ray tube method of manufacturing a cathode ray tube.

摘要

A cathode ray tube in which a glass-enamel layer having particles with a secondary electron emission coefficient smaller than 1, for example Cr2O3 particles, is provided in the neck. The percentage of particles exceeds approximately 30 % and the surface resistance ranges between 10<1><0> and 10<1><4> OMEGA / &squ& . 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. <IMAGE>
