DEVICE AND METHOD FOR INTRODUCING HYDROGEN INTO FLAT DISPLAYS

摘要

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 (14) 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 (15) and the accumulator material (21) 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 (14) is working, the switching on of said heater (19) being arranged in order to bring the wall (15) itself to a previously calculated temperature.
