An improved getter assembly for use in cathode ray tubes, and particularly in cathode ray tubes that require a clear area or window, the getter assembly including a container with getter diffusion directing tabs extending from the sidewall of the container in a direction away from the window area.

Getter assembly with diffusion directing structure

A color cathode ray tube incorporates a getter assembly and contactor structure that is introduced into the interior of the tube through the open neck subsequent to the sealing of the panel and funnel portions of the envelope, and a mounting bracket affixed to the internal magnetic shield of the tube for receiving and securely holding the getter assembly and contactor structure, enabling the use of non-bakable getter material in feedback-type tubes.

Getter and contact assembly for a cathode ray tube

A color cathode ray tube having a phosphor pattern on the mask and a window in the tube wall to allow external detection of the phosphor emissions, also incorporates arc limiting features including a high resistance coating in the neck region of the tube and a getter designed and placed to direct getter flash away from the neck, window and mask areas. Such a tube is useful, for example, for high resolution color displays having an automatic convergence feature.
