Abstract
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.
