This patent discloses a cathode ray tube that 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. Author
