Abstract:
A gas-discharge picture-display panel comprising a plurality of gas-discharge tubes. The gas-discharge tubes are closed on one side by a window. An electrode is arranged at each end of each gas-discharge tube. The length of the gas-discharge tubes is at least twice the dimension normal to the directions of length and the wall of the tube is coated with a phosphor material. A positive column is formed in the gas-discharge tubes and the ultra-violet radiation produced thereby causes the phosphor to luminesce. A device which reduces the ignition voltage of the positive column is connected in series with the gas-discharge tubes. The device produces either a glow discharge or a plasma to reduce the ignition voltage.
Abstract:
Gas discharge display device of a cross-bar type which comprises a cathode system, an auxiliary anode system and an anode system and in which in order to permit the use of low-dissipation control circuits the electrodes of the auxiliary anode system are at right angles to those of the anode system.
