Abstract
Abstract There is disclosed the saturated photon conditioning of a multiple gas discharge device by the provision of a sufficient flux of conditioning photons at each to-be-conditioned cell such that the necessary writing pulse amplitude for each cell is reduced to a minimum level. More particularly, there is provided a conditioning photon flux sufficient to reduce the necessary write voltage of the cell to such a level that the provision of more conditioning photons would not significantly further reduce the amplitude of the required writing pulse.

Claim 1
Independent Claim
143 words
In a process for conditioning the gaseous discharge medium of a plurality of to be addressed display cells for uniform operation at reduced voltage in the operation of a multiple gas discharge display/memory panel comprised of a matrix of display cells formed by opposing dielectric charge storage surfaces and electrode arrays, at least one cell being a pilot cell in the on-state for the photon conditioning of the other matrix display cells, the improvement wherein the sustaining voltage applied to each pilot cell is sufficiently greater in amplitude than the sustaining voltage applied to the other display cells so as to provide a conditioning photon flux sufficient to reduce the required write voltage of the other display cells to a minimum level V.sub..sub.ω100 such that the provision of additional conditioning photons would not significantly further reduce the amplitude of the required writing pulse.

Claim 4
Independent Claim
143 words
A method of determining the minimum voltage V.sub..sub.ω100 for saturation photon conditioning of a plurality of cells in a matrix array in a gas discharge display panel said matrix array of cells being bounded by a plurality of pilot border discharge cells to which a write voltage V B is applied, comprising: at a selected cell in said matrix array most remote from said pilot border, applying a write voltage of a selected magnitude great enough to turn on said selected cell, at said pilot-border cells applying a sustaining signal voltage to said pilot-border cells and then increasing said pilot border sustaining voltage V B and decreasing the write voltage to said selected cell until V.sub..sub.ω100 is reached, wherein V.sub..sub.ω100 is defined as the minimum write voltage amplitude sufficient to assure turn on substantially 100 percent of the time for said selected cell.
