FIG. 6 shows drive waveforms. In FIG. 6, (a) is the sustain electrode 4, (b), (c), and (d) are the scan electrodes 3, and
(E) is a voltage pulse waveform applied to each data electrode 5. A scan pulse which is a negative voltage pulse is applied to the scan electrode 3 to sequentially scan, and in synchronization with this, a positive voltage pulse corresponding to desired display data is applied to the data electrode 5. The writing discharge generated thereby is sustain-discharged by sustaining pulses applied to the scan electrode 3 and the sustain electrode 4 and having negative polarities and opposite phases to each other, and display is performed. The display color is obtained by exciting the phosphor 9 formed on the data electrode 5 with ultraviolet rays generated by discharge. According to the drive waveform, as shown in (b), (c), and (d), writing of display data is performed by sequentially superposing scanning pulses on the scanning electrodes 3 and scanning, and displaying data pulses in synchronization with the scanning. According to the above application, the discharge is performed between the scan electrode 3 and the data electrode 5. Then, between the sustain pulse A applied between the scan electrode 3 and the sustain electrode 4 and the sustain palace B, the above-mentioned discharge that has been written is sustain-emitted. Further, after repeating the above-mentioned discharge a suitable number of times to obtain a desired gradation,
Discharge is stopped by the erase pulse. The desired display pattern is obtained by the above operation.

によっている。However, according to the drive waveforms shown in FIG. 6, when the frequencies of the sustain palace A and the sustain pulse B are increased in order to increase the brightness of the display, the scanning pulse and the erase pulse are superposed. However, the operation becomes unstable, which hinders high brightness. Furthermore,
In order to perform reliable gradation display by the method shown in FIG. 7, it was necessary to provide the priming period twice in one field period. For this reason, the time taken for one subfield is reduced, which is the second factor that hinders high brightness.
This is because the probability of occurrence of writing discharge in the subfield distant from the priming period is low.

At a peak value of 150 V to 250 V and a time width of 2 μS to 30 μS
Negative voltage pulse of 2 at a time interval of 5 μS to 50 μS
A pulse was applied. On the other hand, the peak value of 150 V is applied to the sustain electrode 4.
One negative voltage pulse having a time width of 2 μS to 30 μS at −250 V was applied. These voltage pulses cause a discharge between scan electrode 3 and sustain electrode 4 to charge scan electrode 3 with a positive charge and sustain electrode 4 with a negative charge. Then, in synchronization with the rising of the last voltage pulse applied to the scan electrode, the negative peak value 1 is applied to the sustain electrode 4.
A charge inversion pulse, which is a negative voltage pulse having a time width of 2 μS to 30 μS at 50 V to 200 V, is applied. This charge inversion pulse causes a weak discharge between the scan electrode 3 and the sustain electrode 4, and inverts the positive charge on the scan electrode 3 and the negative charge on the sustain electrode 4 charged during the priming period, and the scan electrode 3
A negative charge is applied on the upper side and a positive charge is applied to the sustain electrode 4. In the subsequent writing period, according to the display data, the data electrode 5 has a positive peak value of 30 V to 100 V and a time width of 2 μS to 30 V.
A voltage pulse (writing pulse) of .mu.S is applied, and at the same time, a voltage pulse (scanning pulse) of 2 .mu.S to 30 .mu.S in time width with a negative peak voltage of 150 V to 200 V is applied to the scan electrode 3. At this time, when the charge is inverted by the above-mentioned charge inversion pulse, the scan pulse and the negative charge on the scan electrode are overlapped with each other, and a discharge is generated between the data electrode 5 and the scan electrode 3.

As described above, by the presence or absence of the charge inversion pulse, it is possible to control the discharge in the write pulse and more surely generate the discharge.

And a voltage pulse (sustain pulse 1) having a phase opposite to that of the write pulse is applied, and the sustain electrode has a negative polarity of 150V to 20V.
A voltage pulse (sustain pulse 2) having 0 V, a time width of 2 μS to 30 μS, and the same phase as the write pulse is applied. By thus increasing the amplitude of the sustain pulse 2 having the same phase as the write pulse and decreasing the amplitude of the sustain pulse 1 having the opposite phase, the voltage difference applied between the sustain electrodes remains constant, -The voltage difference applied between the sustain electrodes can be reduced. As a result, it is possible to prevent erroneous discharge between the data electrode 5 and the scan electrode 3 and the sustain electrode 4 due to the write pulse without disturbing the sustain discharge. The last erase period is the opposite phase (180
The above-mentioned sustain pulse 1 and sustain pulse 2 having a phase difference of 2 degrees) are applied for two pulses with a phase difference of 90 degrees to maintain the discharge for a desired time and then stop the discharge. A desired image can be displayed by repeating the above driving sequence for each row and subfield.

ことができる。Next, a second embodiment of the driving sequence of the present invention, in which the charge inversion pulse is positively used to simplify the driving circuit, will be described with reference to FIGS. 3 and 4. FIG. 3 is a schematic diagram of the electrode wiring of the second embodiment. FIG. 4 is a timing chart of drive waveforms. In FIG. 4, (A) shows the case with a charge inversion pulse, and (B) shows the case without a charge inversion pulse. The voltage pulses Scan1 and S shown in FIG. 4 are applied to the scan electrodes 3a and 3b divided into blocks in FIG.
Apply can2. Also in this case, when the charge is inverted by the charge inversion pulse as described above, the scan pulse and the negative charge on the scan electrode are overlapped with each other to generate the discharge between the data electrode 5 and the scan electrode 3. On the other hand, when the charge inversion pulse is not applied, the positive charges on the scan electrodes work so as to cancel the scan pulses, and no discharge occurs between the data electrodes 5 and the scan electrodes 3. Due to this characteristic, the write discharge can be controlled for each block. This operation will be described below. Figure 3
Is the electrode wiring when divided into two blocks. As shown in the figure, the scan electrodes commonly connected to each of the sustain electrode groups that are commonly connected and divided into two are configured as a pair. According to this electrode configuration, the voltage pulse Scan applied to the scan electrodes
1 and Scan 2 are commonly applied to the scan electrodes that make a pair with the sustain electrode group divided into two. Therefore, the write pulse applied from the data electrode 5 simultaneously applies the same voltage waveform to the display cells at two locations, one from each of the above-mentioned two blocks. However, as described above, since the write discharge can be controlled for each block depending on whether or not the charge inversion pulse is applied, the charge inversion pulse is applied to Sus1 of the sustain electrode and the charge inversion pulse is applied to Sus2 as shown in the voltage waveform of FIG. If it is not applied, only the block to which Sus1 is applied is selected. Therefore, the drive circuit element on the scan electrode side can be shared, and in the case of the second embodiment of FIGS. 3 and 4, the drive circuit element of the scan electrode can be halved. . As described above, according to this driving method, the number of scan driving circuit elements can be reduced by the number of divided blocks.

Can be prevented by the drive waveform having the charge inversion pulse, the sustain pulse 1, and the sustain pulse 2. Therefore, the operation can be stabilized and an image with high display quality can be realized as compared with the conventional driving method. Further, the drive circuit can be simplified by using the charge inversion pulse differently.
