COLOR PICTURE TUBE HAVING SHADOW MASK WITH IMPROVED SUPPORT |
摘要 |
An improved color picture tube includes a rectangular faceplate panel having two long sides and two short sides. A rectangular shadow mask is suspended at its four corners by support means within the panel adjacent to a cathodoluminescent screen located on the panel. The tube has three principal axes that are mutually orthogonal to each other. These axes include a longitudinal axis which extends through the center of the tube perpendicularly to the center of the panel, a major axis which passes through the center of the panel paralleling the long sides of the panel, and a minor axis which passes through the center of the panel paralleling the short sides of the panel. Each of the support means has a central support axis. The improvement comprises the two support axes on each side of the minor axis crossing a plane containing the longitudinal and major axes,at a point located between the minor axis and a short side of the panel.
