    摘要： The object of the invention is to provide a plasma addressed display device which can adapt the amount of dopant gas released or absorbed by the storage material to a changing real-operating/environment conditions of the display device in order to control the partial pressure of the dopant gas in the channel. Configuration: A plasma addressed display device comprising: a channel substrate (2) provided with an array of interconnected longitudinal channel chambers; a cover sheet (4) extending over the channel chambers (30) and making seals to the channel chambers on a side of an upper face of the chamber, whereby the channel substrate and the cover sheet define sealed channel chambers; a pair of electrodes (3a,3c) located in each sealed channel chamber for selectively ionizing a gas within the channel chamber; a dopant source (53) having a storage material that reversibly absorbs and releases a dopant gas to be mixed with a primary ionizable gas in the sealed channel chambers; and a heater (5H) for heating the storage material. The device is provided with a feedback loop (100-103, 5H) for a control of partial pressure of the dopant gas within the sealed channel chambers, the feedback loop comprising: measurement means (100,101) for measuring a value of a decay time of an electrical conductivity in at least one of the channel chambers from turning off the plasma in the channel chamber; and control means (102, 103) for controlling a temperature of the storage material through the heater (5H) on the basis of the measured value so that the decay time is within a predetermined range.

    摘要： The display device comprises at least one compartment (30, 30', 30'') which contains an ionizable gas (33). Walls of the compartments (30, 30', 30'') are provided with electrodes (31, 32) for selectively ionizing the gas (33), during operation, by means of a direct current. The display device is characterized in that the walls of the compartment (30, 30', 30'') are provided with a layer (20) of a secondary electron-emitting material, the electrons (31, 32) remaining completely or partly uncovered. Preferably, the thickness of the layer (20) exceeds 20 nm, and the secondary electron-emitting material comprises a material of the group formed by magnesium oxide, chromium oxide, silicon nitride and yttrium oxide. Preferably, the display device further comprises an electro-optical layer (35), and a further layer (36) of a dielectric material is situated between the compartment (30, 30', 30'') and the electro-optical layer (35), which further layer (36) is provided with the secondary electro-emitting layer (21) on a side facing away from the electro-optical layer (35).

    摘要： A flat display device, preferably of the PALC type, in which the plasma channels are formed by etching in a substrate laterally-spaced channels and bonding a thin dielectric sheet over the etched substrate. Adjoining each of the channels are shallow ledges, also formed by etching, which serve as recessed areas to receive enlarged ends serving as contact pads for each of the electrodes. Holes are formed in the thin dielectric sheet and contact material deposited on the bonded thin dielectric sheet such that the deposited material makes electrical contact with the underlying electrode contact pads and seals off the holes, which allows a plasma-forming atmosphere to be provided in the channels. This arrangement results in a glass-to-glass interface between the substrate and the thin dielectric sheet, which allows anodic bonding to be employed to assemble the two elements and thus eliminates the frit glass sealing process required in other constructions.
