Multicolor cathode-ray tube with quadrupolar focusing color-selection structure |
摘要 |
CRT comprises a color-selection structure for producing a plurality of quadrupolar lenses, each lens defining a window for passing and focusing portions of electron beams to an associated color group of a target. The color-selection structure comprises (i) a metal masking plate having therein an array of substantially rectangular windows, each window having associated therewith (ii) a pair of first conductors insulatingly spaced from one major surface of the plate and located adjacent opposite sides of the aperture and (iii) a pair of second conductors insulatingly spaced from the other major surface of the plate and located adjacent opposte sides of the window. The CRT includes means for applying a voltage to said plate, means for applying a voltage to said pairs of first conductors and means for applying a voltage to said pairs of second conductors.
