Abstract
A gas discharge display apparatus includes a substrate on which a number of electrodes are formed in a row with a distance therebetween and interconnected through polyphase connections. Bipolar pulse voltages are sequentially applied to each phase of the polyphase connections to thereby cause each of the electrodes to operate alternately as an anode and a cathode on a time division basis, whereby discharge produced between the anode and the cathode is caused to perform self-scanning.
Claims22
A gas discharge display apparatus, comprising:
- a discharge display panel including a plurality of electrodes formed on a substrate with a predetermined distance therebetween, and connecting means for interconnecting said plurality of electrodes so as to enable polyphase pulse voltages to be applied thereto;
- and voltage applying means for applying sequentially bipolar polyphase pulse voltages to said electrodes through said connecting means so that each of said electrodes operates alternately as an anode and a cathode on a time division basis in response to said bipolar pulse voltages and discharge produced between electrodes operating as the anode and the cathode is caused to perform self-scanning.
A gas discharge display apparatus according to claim 2, further comprising a dielectric material on said plurality of electrodes.
A gas discharge display apparatus comprising:
- a gas discharge display panel including a pair of first and second insulation substrates at least one of which is transparent, a plurality of electrodes formed on said first substrate with a predetermined distance therebetween, connecting means for interconnecting said plurality of electrodes so as to enable polyphase pulse voltages to be applied thereto, insulation means inserted between said first and second substrates to define a cavity within which discharge produced between said electrodes is confined and a gas filled hermetically in said cavity;
- and voltage applying means for applying sequentially bipolar polyphase pulse voltages to said electrodes through said connection means so that each of said electrodes operates alternately as an anode and a cathode on a time division basis and discharge produced between electrodes operating as the anode and the cathode is caused to perform self-scanning.
