ABSTRACT:
A gas discharge display apparatus consisting of a gas discharge display panel and a drive circuit for driving a matrix array of display elements formed in the display panel by mutually perpendicular arrays of stripe-shaped anodes and cathodes, the cathodes being sequentially selected during successive scanning intervals and the anodes driven to produce a light-emitting or non-emitting state during each scanning interval in accordance with display data. During each scanning interval, each anode for which the non-emitting state is to be maintained is momentarily driven to the light-emitting state potential during a brief interval, to thereby substantially increase the reliability of display operation during the immediately succeeding scanning interval.
