IMPROVED FRAME/MASK STRUCTURE FOR CATHODE RAY TUBE

摘要

PROBLEM TO BE SOLVED: To provide a cathode ray tube(CRT) with a vibration damper attached on the mask structure with simplicity at a low cost. SOLUTION: A color CRT (1) has a color selective mask (8), on the peripheral surface (28) of which is mounted a mask vibration damper (55) including of two blade portions (50) extending to the both sides of a central portion (51) with the central portion mounted on the surface of the mask.
