Method of manufacturing electronic tube |
摘要 |
The present invention has an object to provide a method of manufacturing an electronic tube capable of eliminating deterioration of image quality due to an excessively high electron reflection effect of a material comprising a metal element with an atomic number not lower than 70 and painted on a shadow mask and deterioration of image quality due to spontaneous peeling of a coat on the surface of the shadow mask. A paint mainly comprising a solated metal oxide or a metal alkoxide of an element with an atomic number not lower than 40 is painted to form an electron reflection coat with an amount of coating of less than 2 mg/cm2 so as to achieve coating on an electron gun side surface of a shadow mask. With this method, an electronic tube with good image quality can be manufactured.
