Device and method for introducing hydrogen into flat displays

Abstract

A device (10) for introducing hydrogen into a flat display (14) of the field emission or plasma addressed liquid crystal type is described, formed of a reservoir (11) containing a hydrogen accumulator material (21) connected to the internal space (13) of the display by means of a wall (15) permeable to the passage of hydrogen gas as a function of the temperature. The device comprises a heater (19) and a heater (22) 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.
