CRT having a tension mask with reinforcing support means

摘要

Cathode-ray tube (1) comprising a frame/mask assembly for selecting colors having a mask (8) and a frame (19), the mask being held under tension by being attached to ends of long sides (9) of the frame, the frame/mask assembly being suspended inside the tube using support means (10) which are able to increase the mechanical rigidity of the frame by support means having longitudinal dimples (40) which cause the long sides of the frame to come together during the high-temperature manufacturing phases. <IMAGE>
