Abstract
A plasma display panel according to this disclosure comprises a plurality of display elements having a dielectric surface upon which charges may accumulate adjacent a plurality of conductors. The conductors are supported by a single substrate in substantially coplanar arrangement so that charge accumulation occurs at different locations on the dielectric. Specifically disclosed is a serial shift display wherein data to be displayed may be inputed at one edge of the panel for display and serially shifted across the panel by selective application of sustaining signals to selected electrodes. Data may be read out of this panel from the opposite end for recirculation or other purposes.
Claims15
A display device having a plurality of display elements, said display device comprising a substrate supporting a plurality of elongated conductors in a substantially planar array, each of said conductors being substantially parallel to the others of said conductors;
- a plurality of first cell means adjacent an end one of said conductors, each of said first cell means including first and second electrodes;
- dielectric means overlying said conductors, said dielectric means having a plurality of elongated surfaces extending substantially normal to the length of said conductors, one end of each of said surfaces being adjacent to a respective one of each of said first cell means;
- confining means for confining a gaseous atmosphere contiguous to said dielectric surfaces and said first cell means, each of said display elements being defined by a region of each of said dielectric surfaces between respective pairs of said conductors, whereby upon application of a discharge potential to a first cell means and a selected shift voltage to the one conductor adjacent said first cell means, said respective first cell means discharges to transfer a charge to the dielectric surface adjacent the said one conductor adjacent said first cell means and whereby upon application of a display voltage to the pair of conductors of a display element, a charge difference accumulated on the dielectric surface adjacent said pair of conductors initiates a discharge in said gaseous atmosphere to reverse the charge accumulation and to sustain display of said element.
A display device comprising dielectric means having a substantially planar surface;
- envelope means contiguous said dielectric means to form an enclosed chamber between said dielectric means and said envelope means, said chamber being contiguous said surface;
- a gaseous atmosphere within said chamber;
- a plurality of elongated conductors arranged in a substantial coplanar, parallel array adjacent said surface and outside of said chamber;
- select means for selectively applying voltages to selected conductors to sustain a display by reversing any charge accumulated on said dielectric means between two adjacent conductors;
- a plurality of first cell means in said chamber and adjacent the portion of said surface adjacent an end one of said conductors;
- means for applying a discharge potential to selected ones of said first cell means to transfer a charge to the portion of said surface adjacent the selected first cell means;
- and dielectric barrier means supported on said surface normal to said elongated conductors, said dielectric barrier means forming a plurality of rows normal to said conductors each terminating adjacent one of said first cell means.
