Abstract

PURPOSE: To provide a detachable push-through type side wall of a picture tube without exposing the side wall by forming the inner surface of a panel glass by non-spherical surface of different curvature to become the periphery of a fluorescent screen equalized to the shape of a cabinet.
CONSTITUTION: Assuming that any one point A of a fluorescent screen end formed on the inner surface of a panel galss 4 is in coordinates (XA, YA, ZA) where ZA is tubular axial direction, the coordinates (XA, YA) are determined by the fluorescent screen end xo, yo, po and radius of curvature RL, RS, r of the fluorescent screen. The tubular axis z may be determined here. That is, assume that the radius of curvature at y-axis section is taken at RPY. Since the coordinates (XA, YA) of the point A is determined, oA is known. Accordingly, by considering the oA section, the radial distance from the center o of the glass 4 is known, to thus determine the radius of curvature PRA at the section oA.
