Abstract
PURPOSE: To form a tri-color phosphor and index signal phosphor on the spherical panel correctly in a constant relation, by exposing the phosphor, applied to the panel inner face, through a groove of the pattern with a stripe-shape transmissive groove provided.
CONSTITUTION: A plane master pattern, with a stripe-shape transmissive groove provided linearly at an equal interval, is formed into a tubular surface shape having the face of curvature in a direction in perpendicular or parallel to the transmissive groove, with a tubular pattern 3 constructed. Accordingly, with a point light source placed in a center of the radius of curvature of a panel 1, further with a face of curvature of the tubular pattern 3 formed in a direction perpendicular to the transmissive groove, the tubular pattern 3 is arranged with its radius of curvature center coinciding with the light source, simultaneously with the light exposed to the phosphors applied to inner face of the panel 1 through the transmissive groove of the pattern 3, thus causing easily a construction of the fluorescent screen capable having a stripe 4 at a uniform pitch on inner surfaces of the spherical panel.
