1 to 17 are views for explaining the configuration of the display device according to the present invention.

Referring to FIG. 1, a display device according to an exemplary embodiment of the present invention includes a plasma display panel 100 displaying an image, a frame 200 disposed on a rear surface of the plasma display panel 100, and a front surface of the plasma display panel 100. It may include a filter 210. The frame 200 disposed on the rear surface of the plasma display panel 100 may include a metal material, and may be referred to as a metal plate, a heat sink, a heat radiation frame, a chassis, or the like.

The plasma display panel 100 may implement an image in a frame including a plurality of subfields.

In detail, as shown in FIG. 2, the plasma display panel 100 includes a rear substrate 211 on which a plurality of second electrodes 213 and X intersect the plurality of first electrodes 202 (Y) and 203 (Z). ) May be included.

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.

In the discharge cell, the address electrode 213 may cross the scan electrode 202 and the sustain electrode 203. That is, the discharge cell is formed at the point where the address electrode 213 crosses the scan electrode 202 and the sustain electrode 203.

A predetermined discharge gas may be filled in the discharge cell partitioned by the partition wall 212.

In addition, a phosphor layer 214 that emits visible light for image display may be formed in the discharge cells partitioned by the partition wall 212. For example, a first phosphor layer that generates red light, a second phosphor layer that generates blue light, and a third phosphor layer that generates green light may be formed.

In addition, the address electrode 213 formed on the rear substrate 211 may have substantially the same width or thickness, but the width or thickness inside the discharge cell may be different from the width or thickness outside the discharge cell. . For example, the width or thickness inside the discharge cell may be wider or thicker than that outside the discharge cell.

When a predetermined signal is supplied to at least one of the scan electrode 202, the sustain electrode 203, and the address electrode 213, discharge may occur in the discharge cell. As such, when discharge is generated in the discharge cell, ultraviolet rays may be generated by the discharge gas filled in the discharge cell, and the ultraviolet rays may be irradiated onto the phosphor particles of the phosphor layer 214. Then, a predetermined image may be displayed on the screen of the plasma display panel 100 by the phosphor particles irradiated with ultraviolet rays to emit visible light.

An image frame for implementing gradation of an image in a plasma display panel is described below. Here, the image frame is different from the metal frame 200 disposed on the rear surface of the plasma display panel 100 of FIG. 1.

Referring to FIG. 3, a frame for implementing gray levels of an image may include a plurality of subfields SF1 to SF8.

In addition, the plurality of subfields may include a sustain period for implementing gradation according to an address period and a number of discharges for selecting discharge cells in which discharge cells will not occur or discharge cells in which discharge occurs. Period) may be included.

For example, in case of displaying an image with 256 gray levels, for example, one frame is divided into eight subfields SF1 to SF8 as shown in FIG. 3, and each of the eight subfields SF1 to SF8 is an address. It can include a period and a sustain period.

Alternatively, at least one subfield of the plurality of subfields of the frame may further include a reset period for initialization.

In addition, at least one subfield of the plurality of subfields of the frame may not include a sustain period.

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.

A driving waveform for driving the plasma display panel is as follows.

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.

For example, although not shown, reflection of light by the mesh-shaped metal layer 216 may be prevented by applying a material having a substantially black color, for example, carbon, on the mesh-shaped metal layer 216. . Alternatively, a material having a substantially black color may be formed or applied under the mesh metal layer 216 to absorb interference light emitted from the plasma display panel.

Can be in contact with (200).

The auxiliary frame 700 may electrically connect the electromagnetic shielding layer 214 to the frame 200. Accordingly, the charges collected by the electromagnetic shielding layer 214 may move to the frame 200 which is the ground GND, so that electromagnetic waves may be shielded.

In addition, the auxiliary frame 700 may not only connect the electromagnetic shielding layer 214 to the frame 200, but also may be in close contact with the side surface of the plasma display panel, thereby reducing the size of the portion W1 on which the image is not displayed. That is, the size of the bezel area in which the image is not displayed may be reduced.

In addition, as shown in FIG. 8, when the plasma display panel is applied, the adhesive layer 810 may be disposed between the side surface of the seal layer 400 and the auxiliary frame 700.

In addition, the first portion 230 of the frame 200 may be in contact with the second portion 710 of the auxiliary frame 700. As such, a predetermined fastening means 800 may be used to contact the first portion 230 of the frame 200 and the second portion 710 of the auxiliary frame 700. Fastening means 800 that can be applied to the present invention is a screw, a pin, a wedge, a rivet (Rivet), and the like. Preferably, the fastening means 800 may be a screw.

Looking at the manufacturing method of the display device according to the present invention having such a structure as follows.

Referring to FIG. 9, a seal layer 400 is formed at an edge of at least one of the front substrate 201 and the rear substrate 211 as shown in (a), and the front substrate 201 and the rear surface as shown in (b). The substrate 211 may be bonded to each other.

Thereafter, an exhaust tip (not shown) may be connected to an exhaust hole (not shown), and an exhaust pump (not shown) may be connected to the exhaust tip.

In addition, by using an exhaust pump, the impurity gas remaining in the discharge space between the front substrate 201 and the rear substrate 211 can be discharged to the outside, and argon (Ar), neon (Ne), and xenon (Xe). Discharge gases, such as these, can be injected in a discharge space.

In this way, the discharge space between the front substrate 201 and the rear substrate 211 may be sealed.

Thereafter, as shown in (a) of FIG. 10, a portion of the front substrate 201 and the rear substrate 211 is cut along a predetermined cutting line CL1 in a state where the front substrate 201 and the rear substrate 211 are bonded together. Can be. Here, it is possible to perform grinding together.

Then, at the cut portion as shown in FIG. 10B, at least one of the front substrate 201 and the rear substrate 211 may be prevented from excessively protruding, and thus the size of the portion where the image is not displayed. This can be reduced.

On the other hand, as shown in Figure 10 (a) it is also possible to cut the seal layer 400 together in the process of cutting a portion of the front substrate 201 and the rear substrate 211. As such, when the real layer 400 is cut, the size of the portion where the image is not displayed may be further reduced.
