CATHODE RAY TUBE HAVING IMPLOSION PROTECTION BAND

摘要

The invention relates to a cathode ray tube 1 and method of making the same, wherein the cathode ray tube 1 has an envelope 2 including a panel 3 connected by a funnel 5, and an implosion protection band 12 that is attached to the panel 3 prior to exhausting during the manufacture of the cathode ray tube. The implosion protection band 12 comprising at least two different materials having different coefficients of thermal expansion.
