Abstract
The novel CRT is similar in structure to prior art CRT's except for the color-selection structure, which, as in the prior CRT's is for producing a plurality of lenses for passing and focusing portions of electron beams to associated color groups of the target. In the novel CRT, the color-selection structure comprises at least one lenticular member having therein an array of windows associated with only one color group, each window having a half-width, r, and a conductive mesh having interstitial dimensions small compared to the phosphor elements in the color groups. The lenticular member is longitudinally spaced a distance, s, from the conductive mesh so that the ratio of the longitudinal spacing, s, to the half-width, r, of the window is much less than unity (s/r<<1), so that the lenticular member and the conductive mesh provide a strong lens action.
