CATHODE RAY TUBE HAVING A TENSION MASK ASSEMBLY AND METHOD OF MANUFACTURING THE SAME

摘要

The invention provides a cathode ray tube (1) having a tension mask assembly (10) and a method of manufacturing the same. The tension mask assembly includes a strand tension mask having non-edged border sections (33) and a plurality of strands (36) which are supported by a tension mask support frame (20). The tension mask support frame includes two opposing support blade members (40) having curved edges to which the strands of the mask are secured. The method comprises supporting the strands by the unetched sections of the mask over the support blade members and applying a tensile force to the strands to maintain uniform alignment of the strands. The strands are then secured to the curved edges of the support blade members by relieving the tensile force and welding.
