Abstract

PURPOSE: To obtain the most efficient photo output of a fluorescent screen by obtaining excellent landing characteristics over the entire fluorescent screen, the inner panel surface, by giving a specific relation between an angle against the tube axis of either the inner panel surface or aperture mask and radiuses of curvature of sections of long and short axes.
CONSTITUTION: As to the color CRT with aperture mask 1 confronted to and arranged on fluorescent screen 3 formed on the inner surface of panel 2 at a fixed interval, either the inner surface of panel 2 or mask 1 should be under the relation of equation (1) when the radius of curvature of the section forming an angle θ against long axis X including tube axis Z in the center of mask 1, and the radiuses of curvature of sections of long axis X and short axis Y are denoted by R, and RX and RY. Then, the other one is formed rotation-symmetrically with a single radius of curvature.
