C. scan cells arrayed in rows and columns and a matrix of display cells arrayed in rows and columns, each scan cell being in operative relation with more than one display cell. The panel also includes a plurality of sustainer electrodes associated with rows of display cells and properly operated in conjuction with the scan cells to select and turn on desired display cells, column-by-column.

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.

The disclosure is of a system for operating a dot matrix display panel including elongated anodes and cathodes oriented transversely to each other to define columns of D. C. scanning cells. An array of quasi A. C. display cells is provided spaced from the D. C. scan cells by an apertured electrode plate. Operation of the D. C. scan cells to transfer glow from a scan cell to an associated display cell is achieved by momentarily turning off the scan cell by the application of a negative pulse to its anode. To prevent the coupling of this pulse to adjacent anodes and spurious operation of adjacent scan cells and display cells, a counter-balancing positive pulse is applied to all anodes. The preferred coupling circuitry includes coupling capacitors which can pass both of these positive and negative pulses.

The disclosure is of a display device having a face plate for displaying information and carrying an electrode assembly which is coupled to the face plate of the display device. The electrode assembly includes an insulating support sheet having an inner surface and an outer surface, on each of which an array of rows and columns of conductive areas is formed. On the inner surface, the rows of conductive areas are electrically connected together to output contact pads at a side edge of the sheet, and, on the outer surface, the columns of conductive areas are electrically connected together to output contact pads along the lower edge of the sheet. Each outer conductive area overlies and is capacitively coupled to an inner conductive area. A column conductor which extends from a contact pad at an edge of the outer surface of the sheet is intimately capacitively coupled to each column of outer conductive areas. The system of the invention includes a microprocessor which drives the columns of conductive areas sequentially and senses the energization of one of these areas to provide display information on the display device.

A display panel includes an array of scanning or priming cells disposed in rows and columns and having electrodes for energizing each column of cells sequentially in a scanning cycle. An auxiliary column of reset cells is provided adjacent to the first column of scanning cells of the series to insure that all of the scanning cells in the column are energized at the beginning of a scanning cycle. In addition, a glass-coated wire electrode is provided adjacent to the column of reset cells, and it is energized in such a way as to insure that all of the reset cells are energized as required.

A method and circuit for operating a gaseous discharge device which, in one form, comprises a plurality of discrete gas cells, each having its own cathode and anode electrodes arrayed in a matrix such that the cells can be activated and sustained in different groupings to represent different characters. The gas cells may be small-area light sources arrayed in rows and columns, with each row of cells having a common cathode electrode, and each column of cells having a common anode electrode. Each cell can be turned on, and caused to strike a glow discharge, by having the required firing potential applied between its anode and cathode electrodes. Cells which have been thus turned on can be kept on, so as to impart a storage or memory characteristic to the matrix, by means of sustaining pulses applied directly to their anodes and cathodes, with no intervening current-limiting impedances being required. The desired operation, that is, the sustaining of glow discharge at a controlled level of current flow and light output, is achieved by properly tailoring the parameters of the sustaining pulses, that is, their amplitude, time duration, and repetition rate.

The panel comprises a gas-filled envelope which contains a series of column cathode strips, which are oriented parallel to each other, and include a first cathode strip, a last cathode strip, and intermediate cathode strips. Means are provided which form, with the cathode strips, columns of priming cells and columns of display cells which, in panel operation, are scanned sequentially and repetitively to display characters. The columns of cells, thus, also include a first column, a last column, and intermediate columns. A two-part reset electrode arrangement is provided adjacent to the first cathode strip and the first column of cells to insure proper start of a scanning cycle. The reset arrangement comprises a column electrode, and a plurality of short horizontal electrode bars which extend between the column electrode and the first cathode strip. The reset electrodes provide excited particles which insure turn-on of the first column of priming cells at the beginning of a scanning cycle.
