Brief description of embodiments of a depot based on magnesia powders on a slab of the display panel

摘要

The invention concerns a method for producing a magnesia based deposit on a display panel glass faceplate (4) dielectric surface, consisting at least in the following steps: generating a spray mist from an organometallic compound of magnesium dissolved in a solvent; directing the spray mist towards the faceplate (4) dielectric surface; evaporating the solvent on approaching the faceplate (4) dielectric surface which is brought to a temperature ranging between about 380 DEG C and 430 DEG C; carrying out a pyrolysis of the organometallic compound bringing about the magnesia based deposit on the faceplate surface and the evaporation of the compound organic radical, said deposit being practically waterproof. The invention is particularly applicable to plasma panels.
