Definitions

  • Two lines of transfer cells are sequentially, selectively activated to transfer information by cell-to-cell interaction from one line of display or information cells to the next such line of display cells on the panel. Reliability of the transfer operation is increased by applying a symmetrical erase signal waveform to the transfer cells during non-transfer periods.
  • a two dimensional, four direction parallel, self shifting method and apparatus for a plasma panel is described.
  • plasma display panel or the plasma display/memory panel.
  • Such plasma display panels comprise an array of gas discharge cells separated from exciting electrodes hy dielectric material. as described in U.S. Pat. No. 3.559.190. Gaseous Display and Memory Apparatus. D L. Bit/.cr. H. Gene Slottow and R. H. Willson. issued Jan. 26. 197 l. and assigned to the same assignee here.
  • the commercial development of such potentially low cost graphic display panels has accelerated the interest in systems which employ terminals using the panels as display devices.
  • An example of such a system is the PLATO l ⁇ / Computer-Based Information System at the University of Illinois and as shown for instance in US. Pat. No. 3.405.457. D. L. Bitzer. issued to the same assignee here.
  • a proposed system for the shifting of data stored in a plasma display panel is presented for example in Self Shift Plasma Display.” Digest of Papers SID International Symposium. Society of Information Display. San Francisco. June. 1972. S. Umcda and T. Hirose. pp. 38-39.
  • the various proposed systems utilize the phenomenon that the applied voltage required to initiate a gas discharge in a cell in the OFF" state but adjacent to a cell in the ON" state is somewhat less than the normally required turn on voltage. There appears to be a ccll-to-cell interaction or coupling mechanism which enables the normally OFF cell to he turned on at a lower voltage level. An explanation for this interaction might he that a high concentration of electrons.
  • ions and metastable atoms are present in the immediate neighborhood of a cell adjacent to ON cells due to the nearness of the gas discharge in the ON cells. These particles apparently contribute to the lowering of the firing voltage of the adjacent OFF cell somewhat in the form of a priming effect. and the lowered turn on voltage is therefore sufficient to start a discharge sequence in the adjacent OFF cell.
  • the present invention provides an information display in which information stored in a plasma display panel can be reliably shifted in all four coordinate directions.
  • a 256- line by 25(i-line section of a fiU-line-per-inch plasma panel has been utilized in a constructed embodiment in order to demonstrate the operational characteristics of a four directional shift technique in accordance with the invention.
  • shifting of information in the panel can occur at a rate as high as 5.000 lines per second.
  • the plasma display panel is arranged such that a serial string of cells and the associated electrodes form the information or display portion of the panel the panel also being provided with a serial string of cells and associated electrodes forming the shifting or transfer portion. Two lines of shifting or transfer cells are provided intermediate each line of information or display cells.
  • all transfer cells adjacent to the display cells in the desired shift direction are activated in such a way as to effect a transfer of the display cell information to the transfer cells.
  • all of the display cells are placed in a clear or erase mode which inhibits any undesired transfer of information to the display cells.
  • the remaining transfer cells are activated in such a manner that the information is transferred from the first line of transfer cells to the second line of transfer cells. and the first line of transfer cells is placed in an erase mode to prevent any undesired accumulation of wall voltage during their inactive. non-transfer periods.
  • the erase mode maintains the transfer cells in a more reliable OFF state.
  • the display cells are re moved from the erase mode and activated so as to transfer the information from the second transfer cells to the display cells. and the second transfer cells are placed in a clearing or erase mode during their inactive. non-transfer period. In this manner the information stored in all of the display cells has been reliably shifted in parallel to the next adjacent display cells in the direc tion of the desired shift.
  • FIG. 1 is a schematic diagram illustrating a one dimensional parallel. self-shift technique in accordance with the present invention:
  • FIG. 2 is a schematic diagram illustrating a two dimensional parallel. self-shift technique in accordance with the present invention
  • FIG. 3 illustrates the timing sequence and the wave forms to provide a one-line shift of information in the plasma panel in accordance with the present invention
  • FIG. 4 is a block diagram illustrating apparatus for providing the sequential wave forms illustrated in FIG. 3.
  • FIG. 1 there is illustrated a portion of a plasma panel including the usual set of respective X and Y crossing electrodes.
  • information can be entered into the plasma panel 10 by coupling appropriate firing or turn on voltages to a respective X and Y electrode such that the desired information can be entered into the associated gas cell.
  • the information is then normally retained in the panel by coupling a suitable sustaining voltage to the panel electrodes.
  • a line voltage generator Vy is connected to every third Y electrode and a line voltage generator V is connected to every other X electrode.
  • the alternate X electrodes are connected to ground to prevent information transfer in an undesired direction on the panel.
  • V and V Two shifting voltage generators are provided as indicated and labeled V and V each of the shifting or transfer voltage generators being connected to every third Y electrode or line of the panel.
  • the crossings of the V, and V electrodes are associated with the information or display cells normally utilized during a non shift operation of the panel. These cells can be addressed to effect a write or erase condition as during standard. well-known plasma panel operation.
  • the crossings of the V electrodes and the respective V and V electrodes are associated with the shifting or transfer cells which are used during a shift operation to temporarily store and transfer the information contained in the display cells.
  • a standard otl-linesper-inch plasma panel having the present information shifting capability. the viewing resolution would be reduced to lines per inch.
  • the arrowhead directions on FIG. 1 illustrate the directions in which shifting of information can be provided on the plasma panel I0.
  • the overall technique for shifting of information is as follows. Initially. it is assumed that in a standard. wellknown manner information can be entered on the V lines that is. the information is entered into the cells associated with the V,- lines. Next. the voltage difference across the cells associated with the first shifting or transfer lines. V is provided such that all of the in formation stored on the V lines is shifted by cell-tocell interaction to the V lines. A voltage difference is then provided across the information or display cells such that all of the cells associated with the V lines go to the OFF state. and the information in the panel has thus undergone one line of temporary shift. In other words. the information formerly present in the information or display cells has been transferred one line up to the next line of shifting or transfer cells.
  • a suitable voltage difference is then provided on the electrodes associated with the second line of transfer or shifting cells. i.e. those cells on lines connected to the V generators, causing by cell-to-cell interaction the shifting of information stored on the V voltage lines to also be stored on the V lines.
  • the transfer cells formed by the crossing of the V, and the V lines were originally the receiving cells receiving information from the V, lines. and are now the initiating cells so that the role that the various cell undertake must be interchangeable.
  • the V lines are erased. and a suitable voltage difference is provided to the display cells such that the information now on the V. lines is also coupled by cell-to-cell interaction to the next adjacent V line.
  • the V lines are erased and the shifting of information from one display line to the next has been completed. To effect a shift of information in the reverse direction from that previously de scribed. the roles of the V and V lines are interchanged.
  • FIG. 2 there is illustrated a plasma panel 12 in which there has been provided shifting generators not only on the Y electrodes but also on the respective X electrodes. Note that the V line generators associated with the panel display cells are connected to every third C electrode. Also respective V and V transfer generators are connected to every third X electrode. Thus. information on panel 12 can be shifted in each of the two dimensions and in each of the four directions illustrated by the arrowheads in FIG. 2.
  • V Vy', V and V correspond to the line generators shown in FIGS. 1 and 2.
  • the waveform identified as V V, in FIG. 3 represents the voltage difference provided between the X and Y electrodes associated with the information or display cells on the plasma panel.
  • the waveform in FIG. 3 identified as V -Vsn represents the voltage difference applied between the electrodes associated with the first Y line of shifting or transfer cells.
  • the last waveform in FIG. 3 identified as V -V represents the voltage difference applied to the second line of shifting or transfer cells of the respective Y electrodes.
  • the voltage pulses of the various line generators have been overlapped to produce the desired cell voltage. It is to be understood. of course. that any suitable voltage generators can be used to provide the resulting desired waveforms.
  • the approach illustrated in FIG. 3 for producing the required cell voltages has several advantages over the methods employed in the prior art.
  • One advantage is that the erase pulse width can now be made arbitrarily narrow without imposing severe switching requirements on the high voltage switching transistors commonly used in the presently available drive circuitry.
  • Another advantage is that it is now a straight forward process to generate symmetrical waveforms. and thereby maintain a more controlled situation with initial wall voltage.
  • a third advantage is that the various line generators produce voltage waveforms with a percent duty cycle which provides a more dependable and efficient operation of the drive circuitry.
  • FIG. 3 also shows reference time intervals of 20 microseconds.
  • a one-line shift of information i.e.. from one line of display cells to the next line of display cells
  • 240 microseconds With reference to FIG. 3. and assuming that there is at least one line of display cells containing information on the panel. the combination of the Vy' and V,- generated waveforms provide the standard square wave sustaining signal waveform from time period. to 1 microseconds to the plasma panel display cells. Between reference and microseconds the combined and line generators provide the standard symmetrical erase waveform so as to maintain all of the transfer cells associated therewith in the OFF state.
  • a normal sustaining signal waveform is applied to the first transfer line and due to the cell-tocell interaction preiously referred to.
  • a series of erase signals are applied to the display cells continuing to about 200 mieroseconds in order to place all display cells in the OFF state (see ⁇ vaveform in FIG. 3).
  • the transfer cells associated with the V and V electrodes are provided with a symmetrical erase signal until l20 microseconds from reference 0. This keeps these cells in the OFF state and prevents erratic and undesired shifting of information.
  • the respective second transfer lines are provided with sustaining signals such that by cell-to-cell interaction the information on the first transfer line is transferred to the second transfer line during the interval 120 to mo microseconds.
  • an erase signal is applied to the first transfer lines so as to maintain the associated transfer cells in the OFF state.
  • the information which had been present on the respective lines of display cells is now located only on the next associated second line of transfer cells.
  • the display lines have the sustaining signal applied thereto so that by cell-to-cell coupling. the information is now also present on the next display line.
  • the erase signal is again applied to the second line of transfer cells associated with line electrodes and V so that these cells are again placed in the OFF state to prevent erratic or undesired shifting in accordance with the invention.
  • the information which was present on respective lines of display cells on the plasma panel has been shifted one line up to the next respective line of display cells.
  • each ofthe transfer cells is maintained in the ()FF state by the symmetrical erase signal applied thereto.
  • the shift sequence shown in FIG. 3 accomplished a one-line shift of information in 240 microseconds which corresponds to about 5.3 meters per second or about 4.000 lines per second.
  • the high voltage level was I55 volts Ill plus or minus 2 volts for the lZ-cyclc shift sequence.
  • lhe sustaining signal pulse width was about 4.5 microseconds and the erase signal pulse width was about 2 microseconds.
  • This shift sequence was reduced to 200 microseconds or 5.000 lines per second. but the shift operation became very sensitive to changes in the high ⁇ oltage level. It has been observed that one important characteristic of the cell-to-cell coupling mechanism is that the larger the voltage applied to the initiating cell. the greater the shift margin attainable.
  • Another important observed characteristic of the coupling mechanism is that the cell voltage of all of the neighboring cells of the receiving cell can contribute to increasing the shift margins attainable. and that making these cell voltages as nearly similar as possible to that of the receiving cell voltage without permitting a discharge to occur enhances the shift margin the greatest. Also. an effective way to control the coupling mechanism is to pulse width modulate the sustaining signal waveforms.
  • V V and V voltage waveform drivers and the respective Y electrode voltage waveform drivers correspond to the line generators shown in H0. 2.
  • driver units are well-known in the plasma panel art.
  • a system clock 14 operates through a well-known driver control logic apparatus 16 to provide the basic system time sequence of FIG. 3.
  • An input interface logic appa ratus l8 interconnects the driver control logic apparatus 16 with an input register containing mode. shift and cell address information being presented from a computer. terminal. or other source.
  • the modes required are as follows: Shift L p; Shift Down; Shift Right; Shift Left: Write; Erase; Bulk Erase; and Sustain.
  • the improved method ofclaim I further including placing the panel line of transfer cells in said erase mode during periods just prior to receiving information from a line of information cells until just after transferring said information to the next panel line.
