Cathode ray tube

摘要

A cathode ray tube having an evacuated envelope including a panel section having a front face portion including a sloped sidewall, the sloped sidewall and an outer periphery portion being joined at mold match line, a neck containing therein an electron gun assembly, and a funnel section integrally coupling the panel section and the neck together. The sloped sidewall of the front faceplate has an angle which is in a range of 1.5 to 3 degrees to the tube axis, and a reinforcing band attached by a thermal shrink fit technique to and clamped around the outer periphery of the panel section. The reinforcing band is positioned around the panel section at a predefined position in which a circumferential bending line on the reinforcing band is offset from the mold match line of the cathode ray tube toward the neck.
