ABSTRACT:
A plasma discharge display device including at least one channel defined between opposing walls and containing an ionizable medium. Electrodes are employed for the application of potential differences whereby the medium will emit light proximate the electrodes. The electrodes include first and second AC electrodes on opposite wall surfaces, and third and fourth electrodes for developing a DC discharge in the vicinity of the first and second AC electrodes. The channel is divided into individual cells by means of insulating walls, and the DC discharge serves to prime individual cells, this discharge being developed at succeeding cells. The potential differences achieved by the AC electrodes across a given cell are selectively imparted whereby a primed cell can be caused to emit light. Thereafter, continued operation of the AC electrodes will maintain the light emission in the selected cells to provide a continuous display.
