ABSTRACT:
Electrically insulating surfaces of a cathode ray tube are covered with a film of an organic material (211). This improves the high-voltage behavior of the cathode ray tube. The film is applied by a method in which a solution comprising an organic material is applied, which is allowed to dry and is subsequently caused to decompose partly.
