ABSTRACT:
A system for reading out information in a plasma display memory panel having a set of X and a set of Y electrodes is disclosed in which a forward current is conducted through unidirectional conducting devices having a charge storage effect, for example, charge storage diodes, connected to the X or Y electrodes; a read voltage is applied to one of a selected one of the Y sets of and X electrodes; a charging current due to the read voltage is conducted through the charge storage diodes in a backward direction making use of their backward recovery time; a gas discharge current, after the charging current terminates, flows in the stray capacitance of the selected X or Y electrode, raising its potential relative to the ground potential; and the potential rise is detected to thereby effect read-out of the information.
