Color picture tube

Abstract

Abstract PURPOSE: To raise the resistance of a conductive film against scraping caused by the touch of a blub spacer by replacing only the conductive film touched by the bulb spacer of the wall inside a neck tube with a conductive frit glass. CONSTITUTION: The upper surface of the conductive film 4 formed on the inner wall of the neck tube 1c is covered with the conductive frit film 8 composed of a mixture of silver powder as a conductive material and a frit glass. In this case, the conductive frit film 8 is formed by coating a mixture of 5W98% (based on the conductive frit glass) silver powder, the conductive frit glass, and a hydrophilic polyvinyl alcohol as a binder on the conductive film 4 in a thickness of 0.05W500μm (after being baked), followed by baking.
