Abstract
The present invention provides an implosion prevention tension band for use in a cathode ray tube (CRT) . The CRT includes a faceplate panel with a substantially flat viewing faceplate and a peripheral rearwardly extending sidewall having an inside blend radius from the viewing faceplate to the sidewall . The tension band is a single layer band surrounding the panel and having a predetermined width extending rearwardly from near the faceplate to at least half the distance between the rear edge of the inside blend radius and the rear edge of the sidewall . According to another aspect of the present invention, the tension band includes a plurality of tension adjusting features being positioned at locations around the band aft of the inside blend radius in such manner that the stresses in predetermined areas of the panel are reduced.
