Abstract
PURPOSE: To focus on into a photo conductive screen sharply and strengthen the structure of the glass plate so as to prevent it from the damage by arranging to make the thickness at the outer-peripheral part of a thin glass plate to be thicker than that of the region to be scanned by the electron rays of the central part.
CONSTITUTION: On the surface of the sheet of clear glass 1, the sheet of glass 4, and the transparent electric conductive film 5, and the photo conductive film 6 are fixed in turn through the bonding agent 3. By utilizing the signal electrode 8 with the indium material 7, the electron gun 9 is sealed into the opening edge of the outer tube 10. The thickness of the outerperipheral place of this sheet of glass is more thicker than that of the region scanned by the electron rays at the central part (10W20μm at the central part, 40W50μm at the outerperipheral place). Such structure is obtainable by etching with hydrogen fluoride. Due to the above procedure, it can be achieved that images on the photo conductive film become sharp and the strengthening of sheet of glass is improved so as to prevent damages.
