point of trivia: can you count how many vertical wires are strung across a Trinitron monitors' shadow mask?? I used to work at Sony for a long time, we had a TV assembly line next door :) If you can see the vertical wires, you still have very good eyesight... bye, Said In a message dated 4/16/2010 04:55:35 Pacific Daylight Time, cfhar...@erols.com writes:
Are they really? For some reason, every Trinitron I have ever seen has clusters of little stick on magnets placed here and there on the back of the glass envelope. The trinitron has a shadowmask. It is a grill of highly tensioned wires that are positioned just behind the screen. The original trinitron tube was a little 5 inch diagonal CRT. It had to be small because the wires tended to vibrate if the set was bumped, and that made for some very odd displays. The later larger tubes had horizontal titanium wires welded to the backs of the shadow mask wires every 5 or 10 inches, to prevent the psychedelic color fest that happened when the CRT got bumped. The trinitron has three very carefully aligned cathodes in the gun. They are positioned side-by-side, creating the slight different projection angles necessary to cause the long vertical slots formed by the shadow mask to eclipse the appropriate color bands on the screen. I'm not sure what you are describing; it sure sounds cool; but it isn't a trinitron. Can you find some references? I'd like to read up on it. -Chuck Harris _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
