Abstract: A display device including an electron tube for image reproduction comprising an electron source having a substantially flat emissive surface and comprising a display screen discrete points of which are caused to luminesce by electrons impacting upon a luminescent substance. The selection of the points to be caused to luminesce is performed with the aid of two grids arranged between the electron source and the display screen, each of which have non-intersecting electrodes, a so-called cross-bar. The surface of at least one grid facing the electron source is provided with an insulating or poorly conductive plate having closely adjacent, substantially parallel, narrow passages. The passages have conductive surfaces. The surface of the plate in which the passages are opening out and on which no grid is provided is covered with an electrically conductive layer. The passages are, in particular, secondary-emissive.

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.
