Cathode ray tube having an improved front panel |
摘要 |
A color cathode ray tube includes a front panel having a phosphor screen deposited on its interior surface. A contour of the interior surface is configured such that a radius Rx of a surface curvature of sections parallel to a horizontal axis and a radius Ry of a surface curvature of sections parallel to a vertical axis of the front panel are substantially constant, respectively, within a screen area of the phosphor screen.
