Abstract (en)

[origin: EP1154456A2] Protective layer of the plasma screen is made from crystalline diamond, aluminum nitride, aluminum gallium nitride, boron nitride and tetrahedral amorphous carbon. Plasma screen comprises a front plate (1) with a glass plate (3) on which a dielectric layer (4) and a protective layer (5) are applied; a support plate (2) equipped with a phosphor layer (9); a ribbed structure (12) which divides the space between the front plate and the support plate into plasma cells which are filled with a gas; and electrode arrays (6, 7, 10) arranged on the front plate and the support plate for producing quiet electrical discharges in the plasma cells. Preferred Features: The gas is xenon in an amount of over 7 volume %.
