Definitions

  • the present invention relates to a method for generating the control signals of an alternating type plasma panel. It also relates to plasma panels of the alternative type controlled by signals developed by this process.
  • Plasma panels of the alternative type are well known in the prior art, in particular by French patent application No. 78.04893, published under No. 2,417,848, in the name of THOMSON-CSF and by the article published in the "THOMSON-CSF Technical Review", June 1978, volume 10, N 2, pages 249 to 275.
  • These panels include a large number of cells arranged in a matrix form. Each cell is formed by the gas space located at the intersection of two electrodes belonging to two networks of orthogonal electrodes and is subjected to control signals constituted by the difference of the voltages applied to the two electrodes between which it is located.
  • control signals mention may be made of the registration signals which cause the cells to ignite, the erasure signals which extinguish the cells and the maintenance signals which keep the cells in their initial state, namely the state off, i.e. the status on.
  • the recording and erasing signals are selective signals which must not cause recording and erasure only for the selected cells.
  • any cell C xy is only registered if its two electrodes, x and y, receive adequate voltages, V x and V, which make it possible to obtain the signal at the terminals of this cell and of it alone. of registration.
  • the voltages V x and V y making it possible to obtain the inscription of the cell C x y differ from the voltages V 'x and V' y making it possible to obtain its erasure.
  • the present invention makes it possible to solve the problem of displaying images using an alternating plasma panel by eliminating the drawbacks of variable luminance and increased writing time, and this without modifying the memory effect of the panels.
  • plasma of the alternative type is
  • FIG. 1 schematically represents four cells C 11 , C 12 , C 21 and C 22 of a plasma panel which are located at the intersections of two horizontal electrodes x 1 and x 2 and two vertical electrodes y 1 and y2.
  • FIGS. 2e, f, g, h show the control signals applied to cells C 11 , C 12 , C 21 ' C 22 and which result from the difference in voltages applied to the two electrodes between which each cell is located. .
  • Figures 3e to 3h show the control signals applied to cells C 11 , C 12 , C 21 , C 22 . Only the signal applied to cell C 11 allows erasure thanks to the linear growth part of the voltage from O to Empty at time t 4 at time t 5 .
  • the four signals applied to the cells carry out the maintenance of the cells because of the rising edge towards V 1 existing at time t 1 and the falling edge towards - V 1 existing at time t 3 . Only cell C 11 is deleted, the other cells are maintained in their initial state.
  • FIGS. 5a to 5k the selective part of the voltages has been shown in broken lines, that is to say that which is not identical for all the electrodes and all the cells of the panel and which extends in the 'example chosen from t 3 to t 4 .
  • FIGS. 5a to 5k the non-selective part of the voltages, which is identical for all the electrodes and all the cells of the panel, and which aims to apply to all the cells a maintenance signal constituted, is shown in solid lines. a positive part of amplitude V 1 and a negative part of amplitude V 1 .
  • the non-selective part is obtained by providing a positive part of amplitude V 1 from t, to t 2 for the voltages Vy 1 , Vy 2 and Vy 3 and by providing a positive part of vacuum amplitude t 5 to t 6 for voltages V x1 and V x2 .
  • the form, amplitude and duration of the various selection, non-selection, registration, erasure or maintenance voltages are chosen so that the cells receiving the selection voltage on an electrode and the other electrode the voltage of registration, erasure or maintenance are registered, erased or maintained in their initial state. On the contrary, the cells receiving the non-selection voltage on one electrode must be maintained in their initial state whatever the voltage applied to the other electrode of these cells.
  • One carries out, simultaneously and selectively, for a given row or column, the recording, the deletion and the maintenance of the cells.
  • each network receives, during a given cycle, only two types of voltage, selection or non-selection, specific to this cycle.
  • the method according to the invention makes it possible to solve the problem of displaying successive images by plasma panel.
  • the electrodes of one of the networks therefore receive a voltage chosen only from the ins voltages cription or erasure.
  • control circuits of the plasma panel allowing the implementation of this process, they follow directly from those described by the patent application No. 78.04893 already cited.
