ABSTRACT:
Cathode ray tubes with optical windows in the sidewall or funnel portion thereof are provided with transparent conductive films of metal oxide on the inner surface of the funnel in the window area. Such films provide electrical continuity with the internal conductive coating of the tube, while permitting optical viewing. The films are produced by in-situ pyrolysis of films of metal resiantes in organic solvents.
