| abstract |
A display device comprising a channel plate (39) having channels (30, 30', 30'') containing an ionizable gas (33), and walls of the channels (30, 30', 30'') being provided with electrodes (31, 32) for selectively ionizing the ionizable gas (33) during operation. The display device further includes an electro-optical layer and means for activating said electro-optical layer. The display device is characterized in that the ionizable gas (33) comprises a gas of the group formed by hydrogen, deuterium and deuterium hydrogen, and in that the display device is provided with means for supplying hydrogen, deuterium or deuterium hydrogen to the ionizable gas. Suitable materials include VZ2, LZ3, PdZ0.6, LaNi5Z6, LaNi2Zx, LaCo5Zx, Zr-Mn-Zx or Pd-Ag-Zx, where L is a lanthanide and Z is hydrogen and/or deuterium. The means are preferably situated in a recess (48) around the channel plate (39), in the pump connection (45) and/or they form part of the electrodes (31, 32). |
