Abstract (en)

[origin: US4804883A] 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.
