CRT having a shadow mask vibration damper

摘要

The invention provides an improved vibration damper for use in a tension mask assembly of a CRT. The improved vibration damper is provided along edges of a tension mask which is attached to a support frame. The vibration damper consists of an elongated strip member having first and second ends mounted to a surface of the tension mask along its borders. A substantial portion of the elongated strip member located between the first and second ends lies in frictional contact with the tension mask to receive vibrations induced in the mask.
