A manufacturing process for the production of plasma display panels is provided which allows obtaining in a simple way displays in which getter materials deposits are present in contact with the atmosphere present in channels or cells of the display. The process includes a step of forming the getter material deposits on a free surface of the magnesium oxide layer at positions essentially corresponding to contact areas between the front glass panel and the barriers on the rear glass panel of the display panel.

Process for the production of plasma displays with distributed getter material and displays thus obtained

The invention teaches a system suitable for use in a water-sensitive electronic device which comprises two superimposed layers, the first material of which is formed of a material capable of sorbing hydrogen, the second material formed of a material capable of converting water into hydrogen; a screen of the type with light-emitting organic diodes comprising the system according to the invention.

Systems for conversion of water into hydrogen and sorption of hydrogen in electronic devices

A device ( ) for introducing hydrogen into a flat display ( ) of the field emission or plasma addressed liquid crystal type is described, formed of a reservoir ( ) containing a hydrogen accumulator material ( ) connected to the internal space ( ) of the display by means of a wall ( ) permeable to the passage of hydrogen gas as a function of the temperature. The device comprises a heater ( ) and a heater ( ) for bringing respectively the wall and the accumulator material to the desired temperatures, or a single heater which carries out both cited functions. There is also described a method by which the device is activated whenever the flat display is working, the switching on of said heater being arranged in order to bring the wall itself to a previously calculated temperature.

Device and method for introducing hydrogen into flat displays

Nonevaporable getter alloys containing Zr, Co, and a third component A selected from the rare each metals and mixtures thereof, e.g., mischmetal. A most preferred alloy contains about 80.8 wt % Zr, about 14.2 wt % Co, and about 5 wt % A. These alloys are advantageous because they are suitable for general use, i.e., they have a relatively low activation temperature, are capable of sorbing a wide variety of gases, and minimize the environmental and safety risks associated with known nonevaporable getter alloys.
