Abstract: The CRT has a color screen, an electron gun and a deflection device. The screen has a front plate (10), and two sets of conductive tracks (12,13), and a phosphor layer (11) applied to it. A device receives signals generated by the conductive tracks, and a device supplies correction signals to the deflection device. The conductive tracks are partially covered by an electrically insulating layer (14).

Abstract: The invention describes a plasma display screen wherein the generation of light in the plasma cells takes place in a more efficient manner. This is achieved by employing a material in the protective layer (5) that, upon excitation by UV photons, emits light itself, preferably in the UV-C range.
