A gas discharge type display device for displaying characters and pictures by utilizing a gas discharge, and a method of producing the same. This gas discharge type display device includes first and second base plates held together in a mutually opposed and closed state, with a rare gas sealed in the closed region; first electrode wires embedded in the first base plate; second electrode wires disposed in the second base plate; display electrode bodies electrically connected to the second electrode wires; a first partition wall which is formed between the first and second base plates to surround said display electrode bodies, whereby it is capable of forming discharge cells and also auxiliary discharge cells capable of feeding priming fire to the discharge cells; a second partition wall joined at one end surface thereof to the first base plate and at the other end surface to the end surface of the first partition wall; and a notch formed in the second partition wall to allow the discharge cells and the auxiliary discharge cells to communicate with each other.

Gas discharge type display device and method of producing same

A method for driving a gas discharge display panel consists of the steps of applying a writing pulse on a specific display electrode line selected from display electrode lines arranged side by side in the panel, applying a scanning pulse on a specific scanning electrode line selected from scanning electrode lines which are arranged side by side and cross the display electrode lines to produce writing gas discharge in cooperation with the writing pulse in a specific discharge cell arranged at an intersection space between the specific display electrode and the specific scanning electrode line, and applying a series of maintaining pulses subsequent to the scanning pulse on the specific scanning electrode during only a maintaining period to produce maintaining gas discharge subsequent to the writing gas discharge in the specific discharge cell, the maintaining gas discharge being intermittently produced in synchronism with the maintaining pulses. The scanning pulse is applied in synchronism with the writing pulse. The maintaining gas discharge is stopped without applying any pulse after the maintaining period passes.

Method for driving gas discharge display panel and gas discharge display

A method for driving a plasma display panel comprising a plurality of first electrodes disposed in parallel with each other, a plurality of second electrodes disposed in parallel with each other and perpendicular to the first electrodes, the second electrodes having a plurality of blocks, and a driving means to apply pulses to the second electrodes, wherein the different electrodes belonging to the different blocks are successively scanned in the predetermined order. Alternatively, the different electrodes may be scanned by repeating applications of pulse to a second electrode belonging to a certain block and to a second electrode belonging to either of the adjacent blocks.
