Abstract
A discharge display device is constructed in the form of a plasma panel in which a gas-filled, gas-tight housing contains, as electrode system components of a primary gas discharge path, an insulating matrix having holes therein spaced at regular intervals in accordance with the number of image points as a carrier of two divided electrodes assigned to the discharge cells. The divided electrodes include metal conductor paths arranged, for example, in rows and columns, in particular an auxiliary anode and a control electrode, and a common surface cathode is arranged in such a manner that electrons emerge from the individual holes of the matrix in a controlled fashion. The electrons enter respective d.c. gas discharge paths provided in an insulating hole matrix, which exhibits the same hole spacing and which is in registry with the first-mentioned hole matrix, and cause the individual, bombarded discharge cells to ignite.
