Definitions
- the present invention is directed to a novel method and circuitry for controlling the border sites of a gaseous discharge display panel having inherent memory of the type as disclosed in, for example, Baker et al. U.S. Pat. No. 3,499,167.
- FIG. 3 illustrate the border erase wave forms
- FIG. 4 (A, B, C, D, E, F and G) illustrate the reduced rate border firing wave forms and FIG. 5 (A, a, c, D, E, F and G) illustrate the four axes border conditioning wave forms.
- a gaseous discharge display panel 10 preferably of the type disclosed in Baker et a1.
- the discharge gap distance in such panels is selected to be between 4 and 6 nuisf'l h paiiefi'fiiscofi stituted by a row conductor plate 11 and a column conductor plate 12 joined in spaced apart relation by a sources as the normal viewing or display area sites of Sealant (not h to p id h f re the panel.
- the present invention provides a system for writing the border which has the capability of:
- the row conductor plate 11 carries a row conductor array 13 in the writing or the information display area V and a row border-array l4 and 15 at 'the sides thereof.
- the column conductor plate 12 is identical, having a column conductor array 16 in the writing or viewing area of the data display area D and border or side conductors l7 and 18 respectively.
- the border conductors are shown as spaced from their respective row and column conductors, but in fabrication of the panel can be one or more end conductors in each array.
- the addressing circuits 20 and 21 for the row conductors and 22 and 23 for the column conductor, respectively, alternate or odd numbered conductors are driven by the odd addressing circuitry and the even conductors are driven'by the even conductor addressing circuits may be as disclosed in Leuck application Ser. No. 135,021 filed Apr. 19,1971 now U.S.
- the present invention is directed to the circuitry for *manipulating the discharge sites located by the border be noted that the border conductors are provided with separate sustainer voltage sources V for the column border conductors l7 and 18 and V for the row border conductors l4 and 15 and like the standard sustainer generators VY and VX are controlled by control timing circuit 30. These timing features are illustrated in the wave form diagrams of FIGS. 2, 3, 4 and 5.
- FIG. 2A labeled V is a square wave voltage wave form which is applied to the row conductors in array 13 via the X addressing circuits 21 and 22 (for the odd conductors 14-15 and 17-18. In this connection it will and even conductors, respectively) whereas the wave form of FIG. 23 labeled V, is the voltage wave form which is applied to the column conductors 16 via the odd addressing circuitry 22 and the even addressing circuitry 23.
- the addressing circuits 20-21 and the addressing circuits 22 and 23 float upon, and are referenced to, their respective sustainer voltages.
- FIG. 2C which wave form labeled V, V,,.
- a write voltage pulse (not shown) is algebraically added to the sustainer wave form voltage shown in FIG. 2C as by application of quarter select voltage pulses on a selected pair of intersecting row and column conductors which, algebraically added to the sustainer voltage at that instant is sufficient to initiate a discharge.
- the addressing of the discharge sites in the panel is, therefore, conventional.
- the voltage wave form labeled V has a magnitude or value of V equal to the normal sustainer value V, (which is approximately 150 volts) plus approximately 90 volts so that for each of the border write sustainers V x8 and V the output voltage as determined by control and timing circuit 30 is V,,.
- This voltage when algebraically added to the voltage of the crossing conductors in the column conductor array 16 (wave form 9, FIG. 2(8)), results in the voltage on the gas having the waveform illustrated in FIG. 2E, namely, V V which, is the difference between the voltage wave form in FIG. 2D and the voltage wave form in FIG. 2B.
- the waveform V shown in FIG. 2F is the output voltage of the border sustainer voltage generator in FIG.
- V 1 labeled V
- the border conductors 17 and 18 for the Y axes have this voltage applied thereto and, combined with the row conductors in array 13 (V, asshown in FIG. 2A), results in the voltage on the gas at the discrete column border sites located by these conductor cross points, as shown in FIG. 2G, namely, V, V
- the comer border sites located by the crossing of border conductors 14-15 with border conductors 17-18 have applied thereto a significantly larger voltages as is exemplified by the differences between the voltage wave form in FIG. 2D and the voltage wave form in FIG. 2F which will assure a reliable turn on of at least the corner border sites.
- FIG. 3 The border erase cycle and wave forms therefor is illustrated in FIG. 3 wherein FIGS. 3A, 3B andd 3C correspond to FIGS. 2A, 2B and 2C and are included to show the timing relationship of the border erase wave forms therewith.
- Power supplies 31 and 32 provide as a small direct current voltages as their outputs V, and V, plus A
- the arranged process consists essentially of modifying the widths of one of the pulses on the border sustainers.
- control timing generator 30 during the border erase cycle sends a signal to the border sustainer generator to cause pulse 50, of FIG. 3D, to be narrower than the normal sustainer pulse width.
- Normal sustainer pulse width are about microsecond in width whereas the pulse width of sustainer erase pulse 50 is about 2 microseconds.
- FIG. 3E shows the summation of the voltage at the sites located by the row conductors 13 (V and the border voltage V
- the border sustainer voltage VX is caused to be at a level of V
- FIG. 3G is shown. Because of the flexibility provided by having the additional power supply, as well as the control over the width of the sustainer pulses, it is possible to separately control the border sites. In the case just described, the border sites are erased during long idle times or when no information is to be displayed on the panel for a long period of time.
- FIG. 4A, 4B and 4C correspond to FIGS. 2A, 2B and 2C, respectively.
- the X marks the. point of site discharge.
- FIG. 4D shows the column border sustainer V wherein the rate of the border sustainer is one-half the normal sustainer rate as shown in FIG. 2D.
- FIG. 4E is the voltage waveform of the gas appearing at the border sites located by the crossings of the column border conductors 17 and 18 with the row conductors in array 13 and FIG.
- 4G shows the voltage waveform at the crossing of the row conductor 14 and 15 with the column conductors in array 16. It will be noted that as compared to the border sustainer voltage wave forms (vyg and V in FIG. 2D and 2F, it will be noted that the rate is approximately one-half the normal sustainer rate. Therefore, the number of discharges is reduced to one-half.
- next succeeding discharge which would of occurred at point 94 does not occur (because the wall voltage is in the same direction as the applied voltage). Accordingly,the rate of discharges is significantly reduced thereby reducing the adverse effects of aging on the panel.
- a similar action takes place in connection with the border sites located by border conductors 14 and 15 at crossing points of the conductors in conductor array 16.
- This process and techniques of reducing the number of firings so as to eliminate or minimize some of the adverse aging effects is an alternative procedure to the procedure of turning off the border sites.
- write signals I are applied to a selected site to enter information to the panel and effect a discharge (K) at that site.
- the border sustainer sources V and V are shifted in the direction of the arrows shown in FIG. 5 to coincide with the leading edge of the address pulses l
- the border sites then fire at the same time as the leading edge of the address signal pulses l
- border conditioning it is intended to mean that the sites are on border and the conductors in each array have potentials on the normal row-column conductors the display area sites are more reliably conditioned by turning the border discharges to occur close in time thereto.
- the V border sustainer potential is the same as the normal sustainer potential V and that the row border sustainer potentials V is the same as the row sustainer VX- trolling the border sites of gaseous discharge display panels which are maintained on for photonic conditioning purposes and provides a border writer for sustaining the border which is independent of a normal sustainer and which is also controllable by the logic signals, permitting writing and erasing of the border and conditioning on all four sides, border firing at reduced frequency or rate which, like erasing the border during idle periods, minimizes the aging effects on the border conductors and, sustaining the border at slightly higher voltage levels which may be reduced during operation of the panel as the aging processes proceed.
- a method of operating a gas discharge data display panel of the type having an insulatingly coated row-conductor array on a first support plate, a insulatingly coated column conductor array on a second support substrate, means joining said plates in spaced apart relation with a gaseous discharge medium between said coated conductor arrays, a selected number of conductors in each said array locating border discharge sites which are used asnon-data display areas,
- the'operating potentials tosaid conductor arrays includes aperiodic voltage for sustaining discharges once initiated, said periodic sustainer voltage being of a magnitude insufficient to initiate a discharge at any site but of sufficient magnitude to maintain discharges once initiated at any site, and a data entering discharge initiating signal voltage for algebraic addition to said sustainer voltage potential,
- controlling said separate sustainer potential to control the on condition of said border sites including the steps of increasing the voltage level of said border sustainer voltage above a selected level for a selected time interval to turn the border on.
- the invention achieves the objectives of con- 2.
- the invention defined in claim 1 including the step of minimizing the aging of said border sites by modifying the rate of discharge at said border sites during long periods of no addressing to the normal viewing area of said panel.
- the invention defined in claim 1 including the step of minimizing the aging of said border sites by applying an erase signal voltage to said border sites preceeding long periods of no information being displayed in the normal viewing area of said panel.
- border sustainer voltage level is higher than the normal sustainer voltage level to said row-column conductor arrays, including lowering the level of said sustainer voltage over a long period of use.
- the invention defined in claim 1 including the step of shifting the time of said border sustainer voltage so that the discharge border sites occur near the time of the leading edge of information write pulses to said row-column conductor arrays.
