ABSTRACT:
An addressing structure uses an ionizable gas to address data storage elements (16) defined by the overlapping areas of multiple column electrodes (18) on a first substrate (48) and multiple channels (20) on a second substrate (54). A layer of dielectric material (46) separates the first and second substrates. Each of the channels is filled with the ionizable gas and includes a reference potential electrode that receives a data drive signal and a row electrode that receives a data strobe signal. For each storage element, the ionizable gas functions as an electrical switch that changes between a conducting or plasma state and a nonconducting or de-ionized state in response to an applied data strobe signal. The ionizable gas functions to either store data in or read data out of the storage element. Data are read out by switching the ionizable gas between nonconducting and conducting states to, respectively, first normalize the voltage across an integrating capacitor (118) and then develop across it a voltage proportional to that of the data drive signal previously stored by the storage element. The data stored in all of the storage elements can be quickly erased by applying ground potential to the column electrodes and applying sequentially positive and negative pulses to the row electrodes. If the storage element includes a layer (44) of material having electro-optic properties and receives incident image-carrying light, the ionizable gas functions to select and store image data across the layer and thereby provide a display system having gray scale luminance.
