Abstract
A plasma addressed display or storage device includes a substrate and at least first and second plasma electrodes on an upper surface of the substrate. The first plasma electrode is connected to an external potential and the second plasma electrode is not ohmically connected to an external potential.
Claims8
A plasma addressed display or storage device comprising:
- a substrate,
- at least first and second plasma electrodes on an upper surface of the substrate,
- a layer of insulating material over the plasma electrodes,
- a cover sheet spaced from the layer of insulating material,
- ionizable gas between the cover sheet and the layer of insulating material,
- an array of data drive electrodes, the cover sheet being between the data drive electrodes and the layer of insulating material,
- a layer of electro-optic material between the data drive electrodes and the cover sheet, and
- a means for ohmically connecting the first plasma electrode to an external potential,
- and wherein the second plasma electrode is not ohmically connected to an external potential.
