PLASMA DISPLAY PANEL AND METHOD OF MAKING SAID PANEL Russian patent published in 2010 - IPC H01J11/02 H01J17/16 

FIELD: physics.

SUBSTANCE: when making a plasma display panel (PDP) magnesium alkoxide (Mg(OR)₂) or magnesium acetylacetonate with purity of 99.95% or more are prepared in liquid form and hydrolysed by adding a small amount of acid to the solution. That way, a magnesium hydroxide gel forms which is a magnesium oxide precursor. By burning the gel in air at 700°C or higher, a powder is obtained, which contains MgO 16a-16d particles with a NaCl type structure with crystal faces having crystal-lattice orientation (100) and (111), or with crystal faces having crystal-lattice orientation (100), (110) and (111). Powder in form of a paste is deposited on a dielectric layer 7 or on a surface layer 8. MgO 16 powder forms a protective layer.

EFFECT: improved protective layer, possibility of using the PDP at low voltage, the PDP can display high quality images through prevention of dependency of discharge delay from spatial charges.
