PROJECTION TELEVISION TUBE SYSTEM |
摘要 |
A color projection television receiver and projector having three color tubes mounted in fixed relation and in predetermined location relative to a screen for projecting three color pictures in registration thereon. Accurate registration of the pictures results from a projection tube structure adapted for accurate reproducability in production, whereby field adjustment is minimized. The tube structure employs a mounting barrel accurately suspended within the evacuated envelope and supporting a phosphorcoated target and a projection mirror. A Schmidt correction lens is mounted externally to the envelope of each tube. |
