Abstract
There is disclosed the conditioning of a gas discharge display/memory panel by applying a high voltage one cycle pulse to the non-utilized discharge cells of the panel. There is particularly disclosed a conditioning process for a multiple gas discharge display/memory panel having a plurality of discharge cells formed by a series of transversely positioned electrodes, the discharge cells being addressable in a series of matrices, each addressable matrix having a relative size of C by R discharge cells with a spacing between adjacent matrices of at least one column or one row of not-to-be addressed cells, and at least one high voltage cycle pulse being supplied to the not-to-be addressed cells of a matrix so as to condition the to-be addressed cells within the matrix.
Claims8
In a process for conditioning multiple gas discharge display/memory panel, having a relatively large geometrical area, and containing an ionizable gaseous medium and having a plurality of discharge cells formed by a pair of transversely related electrodes, said discharge cells being geometrically arranged in rows and columns and the panel being electrically addressable in a plurality of matrices for displaying alphanumeric characters formed by selected rows and columns of addressable discharge cells, each addressable matrix within said panel having a relative size of C by R discharge cells with a spacing between adjacent addressable matrices of at least one column or one row of not-to-be addressed discharge cells and a series of panel border discharge cells being maintained in the one state to constitute pilot cells, the improvement which comprises conditioning a selected portion of the panel by supplying at least one high voltage cycle pulse to the not-to-be addressed cells between addressable matrices so as to photonically condition the to-beaddressed cells within the adjoining matrices.
In a multiple gas discharge display/memory panel having a large geometrical area and containing an ionizable gaseous medium a plurality of discharge cells openly photonically connected formed by a series of transversely related electrodes, said discharge cells being geometrically arranged in rows and columns, and the panel being electrically addressable in a plurality of individual sub-matrices formed by rows and columns of discharge cells, each addressable sub-matrix having a relative size of C by R discharge cells with a spacing between adjacent sub-matrices of at least one column or one row of not-to-be addressed discharge cells, the improvement wherein the not-to-be addressed cells are in open photonic communication with said addressable submatrices and are connected to a high voltage cycle pulse source so as to discharge at least a portion of the not-to-be addressed cells and condition the to-be addressed cells within each said sub-matrix.
