Abstract
The disclosure is of a display panel comprising a gas-filled envelope made up of a base plate and face plate and having anode and cathode electrodes supported on the base plate and forming an array of D. C. gas discharge cells. An apertured electrode arrangement is mounted between the base plate and face plate and defines, with an A. C. electrode on the face plate, an array of quasi A. C. gas discharge display cells, there being one A. C. cell for each D. C. cell. The A. C. electrode is a transparent conductive film which is coated with insulating material. The D. C. gas discharge cells are arrayed as a plurality of columns of scanning cells and, adjacent to the first column of these scanning cells, in a column of reset cells which are turned on before the first column of scanning cells are turned on in a scanning cycle. The panel also includes a keep-alive arrangement which comprises an electrode on the face plate of the envelope, the electrode being coated with a layer of insulating material, to form an A. C. electrode, and this A. C. electrode is positioned in alignment with apertures in the apertured electrode arrangement, in which it generates excited particles for the reset cells. These excited particles assist the firing of the reset cells.
