Abstract
A shadow mask mounting in a color cathode ray tube comprising an evacuated envelope having a longitudinal axis and including a generally rectangular faceplate, which faceplate is sealed to one of opposite ends of the evacuated envelope and includes a phosphor deposited screen lying generally perpendicular to the longitudinal axis. The mounting comprises a generally rectangular rigid support frame, a finely perforated shadow mask mounted across the support frame and having a skirt connected to the support frame, a plurality of positioning engagements formed in one of the skirt of the perforated shadow mask and the support frame, and a corresponding number of mating engagements formed in the other of the skirt of the perforated shadow mask and the support frame so that, when the perforated shadow mask is mounted on the support frame, the positioning engagements can be engaged with the mating engagements to position the shadow mask relative to the support frame in a plane perpendicular to the longitudinal axis of the evacuated envelope.
