摘要

An indicator tube includes a pair of common memory plate electrodes (3, 4) and independent address XY electrode groups (1, 2) separate therefrom. When an address discharge is to be carried out by the XY electrode groups (1, 2) from a state in which no wall charge uniformly exists on wall surfaces of the pair of memory electrodes (3, 4) in all cells on a picture screen or on a line to be addressed, the driving method includes holding one of the pair of memory electrodes (3, 4) at a potential higher than a discharge space potential generated by an address discharge in a range such that a discharge is not caused on the low voltage side of the address electrode during an address period, holding the other memory electrode (3, 4) at a potential lower than the discharge space potential in a range such that a discharge is not caused on the high voltage side of the address electrode, selectively accumulating charged particles generated by the address discharge in cells disposed at the positions corresponding to an image as negative and positive wall charges, and continuously effecting a display discharge or memory discharge utilizing a presence or absence of the wall charges as position information. A variation of this driving method is used when an address discharge is to be carried out by the XY electrode groups (1, 2) from a state in which positive and negative wall charges uniformly exist on wall surfaces of the pair of memory electrodes (3, 4) in all cells on a picture screen or on a line to be addressed.
