Here, the first electrodes 202 and 203 may include scan electrodes 202 and Y parallel to each other, and sustain electrodes 203 and Z, and the second electrode 211 may be referred to as an address electrode.

On the front substrate 201 where the scan electrodes 202 and Y and the sustain electrodes 203 and Z are formed, the discharge currents of the scan electrodes 202 and Y and the sustain electrodes 203 and Z are limited and the scan electrodes 202 and Y are restricted. ) And an upper dielectric layer 204 may be arranged to insulate between the sustain electrodes 203 and Z.

A protective layer 205 may be formed on the front substrate 201 where the upper dielectric layer 204 is formed to facilitate discharge conditions. The protective layer 205 may include a material having a high secondary electron emission coefficient, such as magnesium oxide (MgO) material.

The address electrodes 213 and X are formed on the rear substrate 211, and the address electrodes 213 and X are covered on the upper side of the rear substrate 211 on which the address electrodes 213 and X are formed. A lower dielectric layer 215 may be formed that insulates X).

On top of the lower dielectric layer 215, a partition space 212, such as a stripe type, a well type, a delta type, a honeycomb type, etc., is formed on the discharge space, that is, to partition the discharge cells. Can be. Accordingly, the first discharge cell emitting red (R) light, the second discharge cell emitting blue (B) light, and the green (Green) light between the front substrate 201 and the rear substrate 211. : G) A third discharge cell or the like that emits light can be formed.

Meanwhile, the weight of the corresponding subfield may be set by adjusting the number of sustain signals supplied in the sustain period. That is, a predetermined weight can be given to each subfield using the sustain period. For example, the weight of each subfield is 2 ⁿ by setting the weight of the first subfield to 2 ⁰ and the weight of the second subfield to 2 ¹ (where n = 0, 1, 2, 3, 4, 5, 6, 7) can be set to increase the ratio. As described above, gray levels of various images may be realized by adjusting the number of sustain signals supplied in the sustain period of each subfield according to the weight in each subfield.

In FIG. 3, only one image frame is composed of eight subfields. However, the number of subfields constituting one image frame may be variously changed. For example, one video frame may be configured with 12 subfields from the first subfield to the twelfth subfield, or one video frame may be configured with 10 subfields.

In addition, in FIG. 3, subfields are arranged in an order of increasing weight in one image frame. Alternatively, subfields may be arranged in an order of decreasing weight in one image frame. Subfields may be arranged regardless.

Can supply Here, the reset signal RS may include a rising ramp signal (Ramp-Up: RU) in which the voltage gradually rises and a falling ramp signal (Ramp-Down: RD) in which the voltage gradually falls.

For example, the rising ramp signal RU may be supplied to the scan electrode in the setup period SU of the reset period, and the falling ramp signal RD may be supplied to the scan electrode in the setdown period SD after the setup period. .

When the rising ramp signal is supplied to the scan electrode, a weak dark discharge, that is, setup discharge, occurs in the discharge cell by the rising ramp signal. By this setup discharge, the distribution of wall charges can be uniform in the discharge cells.

After the rising ramp signal is supplied, when the falling ramp signal is supplied to the scan electrode, a weak erase discharge, that is, a setdown discharge, occurs in the discharge cell. By this set-down discharge, wall charges such that address discharge can be stably generated can be uniformly retained in the discharge cells.

In the address period AP after the reset period, the scan reference signal Ybias having a voltage higher than the lowest voltage of the falling ramp signal may be supplied to the scan electrode.

In addition, in the address period, the scan signal Sc that falls from the voltage of the scan reference signal Ybias may be supplied to the scan electrode.

Meanwhile, the pulse width of the scan signal supplied to the scan electrode in the address period of at least one subfield may be different from the pulse width of the scan signal of another subfield. For example, the width of the scan signal in the subfield located later in time may be smaller than the width of the scan signal in the preceding subfield. In addition, the reduction of the scan signal width according to the arrangement order of the subfields can be made gradually, such as 2.6 Hz (microseconds), 2.3 Hz, 2.1 Hz, 1.9 Hz, or 2.6 Hz, 2.3 Hz, 2.3 Hz, 2.1 Hz. .... 1.9 ㎲, 1.9 ㎲ and so on.

As such, when the scan signal is supplied to the scan electrode, the data signal Dt may be supplied to the address electrode X corresponding to the scan signal.

When the scan signal and the data signal are supplied, an address discharge may be generated in the discharge cell to which the data signal is supplied while the voltage difference between the scan signal and the data signal and the wall voltage generated by the wall charges generated in the reset period are added. .

In addition, the sustain reference signal Zbias signal may be supplied to the sustain electrode in the address period in which the address discharge occurs so that the address discharge is effectively generated between the scan electrode and the address electrode.

In the sustain period SP after the address period, the sustain signal SUS may be supplied to at least one of the scan electrode and the sustain electrode. For example, a sustain signal may be alternately supplied to the scan electrode and the sustain electrode.

When such a sustain signal is supplied, the discharge cell selected by the address discharge is added with the wall voltage in the discharge cell and the sustain voltage Vs of the sustain signal, and a sustain discharge, i.e., display between the scan electrode and the sustain electrode when the sustain signal is supplied. Discharge may occur.
