Abstract
A gas-discharge display device has a parallel array of anodes and a parallel array of cathodes forming a matrix of anode-cathode cross points or discharge dots. The display device is filled with a discharge gas mixture at the discharge dots or cells. Displaying and scanning are respectively achieved through drive circuits supplying discharges of a layer and a smaller current, or discharges for a longer and shorter time respectively.
Claims13
A gas discharge display device comprising means defining an enclosed space filled with a discharge gas, a plurality of first electrodes and a plurality of second electrodes disposed within said enclosed space, said first and second electrodes oriented to cross one another at cross points with a predetermined gap therebetween, thereby forming discharge dots at said cross points, dielectric barriers disposed within the enclosed space along at least either of said plurality of first electrodes or said plurality of second electrodes, thereby dividing said enclosed space into rows of discharging cells, each of said discharging cells having a scanning discharge and a display discharge portion, said plurality of first electrodes being adjacent said scanning discharge cell portions and spaced from said display discharge cell portions, a driving circuit connected to said plurality of first electrodes and said plurality of second electrodes for sequentially providing said electrodes with first signals causing strong display discharges, and second signals causing weaker scanning discharges, both said display and scanning discharges occurring between the same pairs of one of said first electrodes and one of said second electrodes, respectively.
