Abstract
A PALC panel which includes a layer of insulating material over the plasma electrodes and in which the cover sheet is spaced from the layer of insulating material at a distance of less than about 50 μm.
Claims16
A PALC panel comprising:
- a substrate,
- at least two 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, and
- a layer of electro-optic material between the data drive electrodes and the cover sheet,
- and wherein the cover sheet is spaced from the layer of insulating material at a distance of less than about 50 μm.
