Display system for plasma display panels

Claim 3

A display system comprising: a. a plasma display panel comprising a first plurality of electrodes disposed in a first direction and a second plurality of electrodes disposed in a second direction to traverse the first-mentioned direction and spaced from said first plurality of electrodes for receiving a discharge gas therebetween, and a dielectric layer disposed on said second plurality of electrodes; b. means for sequentially applying lateral discharge voltage between each adjacent pair of said first plurality of electrodes of sufficient magnitude to effect a lateral discharge between said each adjacent pair of electrodes and for sequentially shifting a lateral discharge from each such pair of electrodes to the next; c. means for applying a write signal selectively to said second plurality of electrodes whereby a vertical discharge is established between electrodes of said first and second pluralities in accordance with the timing of the shifting of the lateral discharge and the application of the display information input signal, said vertical discharge being stored as a wall voltage in said dielectric layer; and d. means for applying a sustain voltage between said first and second electrodes to provide a display of the pattern of the wall voltage stored in said dielectric layer associated with said second plurality of electrodes.

Claim 4

A display system comprising: a. a plasma display panel comprising a first plurality of electrodes disposed in a first direction and a second plurality of electrodes disposed in a second direction to traverse the first-mentioned direction and spaced from said first plurality of electrodes for receiving a discharge gas therebetween, and a dielectric layer disposed on said second plurality of electrodes; b. means for sequentially applying lateral discharge voltage between each adjacent pair of said first plurality of electrodes of sufficient magnitude to effect a lateral discharge between said each adjacent pair of electrodes and for sequentially shifting a lateral discharge from each such pair of electrodes to the next; c. means for applying a write signal selectively to said second plurality of electrodes whereby a vertical discharge is established between electrodes of said first and second pluralities in accordance with the timing of the shifting of the lateral discharge and the application of the display information input signal, said vertical discharge being stored as a wall voltage in said dielectric layer; and d. means for applying a sustain voltage between said first and second electrodes to provide a display of the pattern of the wall voltage stored in said dielectric layer associated with said second plurality of electrodes.

Claim 5

A display system as claimed in claim 2, wherein said second plurality of electrodes includes a start electrode, and there is further provided means for applying a start signal to said start electrode to initiate the lateral discharge.

Claim 6

A display system as claimed in claim 2, wherein there is included an interface means and a shift register, said interface means receiving a data signal And providing a display information output signal bearing the data content of the received signal to said shift register means, said shift register means storing the display information output signal and said write signal applying means responds to the stored display information signals for correspondingly and selectively applying said write signals to said second plurality of electrodes.

Claim 7

A display system as recited in claim 2 wherein said first plurality of electrodes includes successive groups thereof and there are further provided plural buses equal in number to the number of electrodes of each such group and connected in common to the corresponding electrodes of each such group, and means for controlling said lateral discharge voltage applying means to apply said lateral discharge voltage between a pair of said buses cyclically and in continuous succession to effect the sequential shifting of the lateral discharge from each such pair of electrodes to the next.
