Title:
COLOR SELECTING MECHANISM FOR CATHODE−RAY TUBE AND COLOR CATHODE−RAY TUBE
Document Type and Number:
WIPO Patent Application WO/2003/001554
Kind Code:
A1
Abstract:
A color selecting mechanism for a cathode−ray tube enabling higher resolution of the cathode−ray tube by further making finer the pitches of grid elements. Slit−shaped electron beam passing openings (22) are parallel arranged in a color−selection electrode thin sheet (21) suspended on a frame. Grid elements (23) are provided among the slit−shaped electron beam passing openings (22). N rows (n is a positive integer) of slot−shaped electron beam passing openings (24) parallel to the slit−shaped electron beam passing openings (22) are arranged in each grid element (23). A high−definition high−resolution color cathode−ray tube having such a color selecting mechanism is also disclosed.
