Abstract: A television picture tube which includes a composite frontal plane comprising a viewing screen which is spherically or aspherically convexly curved relative to the viewer. A convexly curved supplementary plane, preferably made of clear glass, gray glass or machine glass is spaced from the viewing screen by a transparent cast resin layer inserted between the viewing screen and the supplementary pane. The resin layer glues the screen and the pane to one another and has a refraction index which corresponds approximately to that of the supplementary pane and the viewing screen. The supplementary pane is cylindrically curved only about the panes vertical axis and its radius of curvature is significantly larger than the radius of curvature of the viewing screen.

Abstract: Front attachment unit for the cathode ray tube of monitors, television sets or the like, consisting of a sheet of glass, in particular a sheet of gray glass, anti-reflection equipment on the front side and an absorption coating on the rear side, whereby the absorption coating has metallic atoms. The absorption coating is single-layer and made of chromium, a chromium/nickel alloy or silicides. It is anti-statically adjusted and grounded. It is of a thickness which reduces the light transmission compared with a non-coated sheet of glass by approximately a third.
