  • Method and apparatus for frit-sealing high temperature CRT faceplate to conventional CRT envelope
    Patent number: 4194643
    Abstract: A cathode ray tube has an envelope comprised of a first glass and a faceplate comprised of a second glass, both glasses having different thermal coefficients of expansion. The envelope and faceplate are joined by a cylindrical, stress-absorbing glass member flame-sealed at one end to the envelope and frit-sealed at the other end to the faceplate. Importantly, the thermal coefficient of expansion of the stress-absorbing member is less than the coefficients of either the envelope or the faceplate.
