ABSTRACT:
An implosion-resistant cathode-ray tube has an evacuated envelope with a faceplate panel which includes a substantially rectangularly-shaped viewing portion that extends to a peripheral sidewall. The sidewall has corners and oppositely disposed flattened portions. An implosion protection band, having a predetermined width, extends around the sidewall. A plurality of mounting loops are formed in the implosion protection band, in the direction of the width, to accommodate mounting bolts. Each of the mounting loops is closed adjacent to the sidewall to ensure the structural integrity of the implosion protection band.
