FIG. 1 is a schematic configuration diagram of a plasma display device according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view showing a part of the plasma display panel applied to the first embodiment of the present invention.

As shown in FIG. 1, the plasma display device according to the first embodiment includes a plasma display panel 100, a scan electrode driver 200 and a sustain electrode driver connected to the electrodes of the plasma display panel 100. 300 and an address electrode driver 400.

The plasma display panel 100 is composed of a so-called delta type plasma display panel in which three subpixels for generating visible light of red, green, and blue are arranged in a triangle to form a set of pixels. have.

More specifically, as shown in FIG. 2, the plasma display panel 100 includes a rear substrate 10 and a front substrate 30 encapsulated while being disposed substantially parallel to each other at random intervals therebetween. .

Between the rear substrate 10 and the front substrate 30, partition walls 23 partitioning the pixels 120 having a predetermined height and having an arbitrary pattern are disposed. Here, the set of pixels 120 includes three subpixels 120R, 120G, and 120B arranged in a triangular shape as described above.

At this time, the subpixels 120R, 120G, and 120B each have discharge cells 18, which are partitioned off by the partition wall 23.

Since the planar shape of each of the subpixels 120R, 120G, and 120B is substantially hexagonal, in the first embodiment, the partition wall 23 partitioning the subpixels 120R, 120G, and 120B also forms a hexagon. It is formed to achieve. Therefore, the discharge cells 18 of each of the subpixels 120R, 120G, and 120B have a hexagonal box shape with an upper portion opened.

The discharge cells 18 are filled with a discharge gas including xenon (Xe), neon (Ne), and the like required for plasma discharge. Sub-pixels 120R, 120G, and 120B that generate visible light of red (R), green (G), and blue (B), respectively, are formed with phosphor layers 25 corresponding to red, green, and blue, respectively. have. The phosphor layers 25 are formed on the bottom surface of each discharge cell 18 and the side surface of the partition wall 23.

The address electrodes 15 are formed on the rear substrate 10 in the first direction (y-axis direction of the drawing), respectively, and are arranged side by side in the second direction (x-axis direction of the drawing). The address electrodes 15 are disposed to pass below each discharge cell 18 (ie, between the rear substrate and the partition layer).

In addition, the dielectric layer 12 is formed on the entire surface of the back substrate 10 while covering the address electrodes 15. Therefore, the address electrodes 15 are disposed under the layer formed by the partition wall 23.

In addition, the sustain electrodes 32 and the scan electrodes 34 are formed on the front substrate 30 along the second direction (the x-axis direction of the drawing). The sustain electrode 32 and the scan electrode 34 correspond to each other in each discharge cell 18 to form a discharge gap. The sustain electrode 32 and the scan electrode 34 are alternately arranged along the y-axis direction.

Each of the sustain electrode 32 and the scan electrode 34 has a wider width than the bus electrodes 32a and 34a formed on the front substrate 30 along the x-axis direction and the bus electrodes 32a and 34a. and transparent electrodes 32b and 34b formed in a structure covering the bus electrodes 32a and 34a along the x-axis direction.

The bus electrodes 32a and 34a may be made of a metal material having excellent conductance. The bus electrodes 32a and 34a are preferably formed by minimizing their line widths within the range of ensuring conduction in order to minimize shielding of visible light generated in the discharge cells 18 when driving the plasma display panel.

The transparent electrodes 32b and 34b are made of a transparent material such as indium tin oxide (ITO), and are formed in the x-axis direction together with the bus electrodes 32a and 34a. Accordingly, in one discharge cell 18, a pair of transparent electrodes 32b and 34b are disposed to face each other at an arbitrary interval therebetween.

In addition, a dielectric layer (not shown) is formed on the entire surface of the front substrate 30 while covering the sustain electrode 32 and the scanning electrode 34 on the front substrate 30, and a protective film (not illustrated) is formed thereon. C) may be further formed.

Referring to FIG. 1, two address electrodes 15 and 15 correspond to each pixel 120 in the first embodiment. Each pixel 120 is composed of three sub-pixels 120R, 120G, and 120B which generate red, green, and blue visible light, respectively.

Centers of the subpixels 120R, 120G, and 120B constituting the pixel 120 are arranged in a triangular shape. The three discharge cells 18 constituting the pixel 12, that is, two discharge cells 18 among the subpixels 120R, 120G, and 120B are arranged side by side adjacent to each other in the y-axis direction. This arrangement increases the discharge space in the y-axis direction to form a space suitable for discharge, thereby improving the margin.

In addition, at least two of the subpixels 120R, 120G, and 120B constituting one pixel 120 correspond to the same address electrode 15. Two scan electrodes 34 correspond to the one pixel 120. That is, the three subpixels 120R, 120G, and 120B constituting one pixel 120 may be determined by the two address electrodes 15 and the two scan electrodes 34.

In more detail, the two sub-pixels 120G and 120B formed of two discharge cells 18 adjacent in the y-axis direction correspond to one address electrode 15 (Am + 8). The subpixel 120R formed of the remaining one discharge cell 18 corresponds to the other address electrode 15 (Am + 7). The subpixels 120G and 120B of the two discharge cells 18 corresponding to the same one address electrode 15 (Am + 8) have a phosphor layer 25 for generating visible light of different colors.

Further, the subpixels 120R and 120B of two discharge cells 18 neighboring in the x-axis direction correspond to one scan electrode 34 (Yn + 3), and the other one of the discharge cells 18 The subpixel 120G corresponds to the other scan electrode 34 (Yn + 2). The subpixels 120R and 120B of the two discharge cells 18 corresponding to one scan electrode 34 (Yn + 3) have a phosphor layer 25 for generating visible light of different colors.

One pixel 120 corresponding to the scan electrodes 34 (Yn + 3) (Yn + 2) also corresponds to the sustain electrodes 32 (Xn + 4) (Xn + 3). The sustain electrodes 32 (Xn + 4) (Xn + 3) and the scan electrodes 34 (Yn + 3) (Yn + 2) respectively face each other in one pixel 120.

An array of sustain electrodes 32 (Xn + 4) (Xn + 3) and scan electrodes 34 (Yn + 3) (Yn + 2) corresponding to the pixel 120 may be arranged repeatedly. Depending on the selection of 120, it may be set as described above or may be set differently.

In the first embodiment, each of the discharge cells 18 constituting each of the subpixels 120R, 120G, and 120B is arranged in a hexagonal planar shape. Therefore, these radiation cells 18 form a boundary by sides in six directions. Therefore, the extension line of the boundary of the pair of adjacent discharge cells 18 along the longitudinal direction (y-axis direction in the drawing) of the address electrode 15 is along the direction (x-axis direction in the drawing) crossing the address electrode 15. It passes through the center of the adjacent discharge cell 18.

Although the centers of the three subpixels 120R, 120G, and 120B forming one pixel 120 are arranged in a triangular shape, the sustain electrodes 32 and the scan electrodes 34 are formed in a straight line shape. It is.

Accordingly, the sustain electrode 32 and the scan electrode 34 are disposed across the two different subpixels among the subpixels 120R, 120G, and 120B in the x-axis direction on the plane. As a result, each of the sustain electrodes 32 and the scan electrodes 34 is disposed two to one pixel 120 including three subpixels 120R, 120G, and 120B (to be more precise, in one pixel). 3/2 scan electrodes 34 and sustain electrodes 32 are disposed respectively).

The scan electrode 34 (Yn + 3) applies a common voltage while passing through two subpixels 120R and 120B neighboring each other in the x-axis direction from one pixel 120, and the other scan electrode 34. (Yn + 2) applies a voltage while passing through one subpixel 120G in the same pixel 120. In addition, the scan electrode 34 (Yn + 2) applies the common voltage as described above while passing through the two subpixels 120G and 120B of the other pixels 120 neighboring in the x-axis direction.

The sustain electrodes 34 are disposed opposite to the scan electrodes 34. The sustain electrode 32 (Xn + 4) faces the scan electrode 34 (Yn + 3) while applying a voltage corresponding to one subpixel 120B in one pixel 120. In addition, the sustain electrode 32 (Xn + 3) passes the two subpixels 120R and 120G included in the other pixels 120 adjacent to each other in the x-axis direction and applies the same common voltage as described above. The sustain electrode 32 (Xn + 3) opposes the scan electrode Yn + 2 and the other scan electrode Yn + 3 on both sides of the y-axis direction.

Accordingly, the scan electrodes 34 and the sustain electrodes 32 are alternately arranged along the length direction (y-axis direction) of the address electrode 15 to control driving of the pair of discharge cells 18, respectively. do.

Based on one pixel 120, two address electrodes 5 are disposed, and two scan electrodes 34 are disposed (two or three, as described above).

In addition, considering four pixels 120 in the x-axis direction and four pixels 120 in the y-axis direction, the number of scanning electrodes 34 passing through each pixel 120 is six on average, and the address electrode 15 Is eight.

As in the first embodiment, when two address electrodes 15 correspond to each pixel 120 and 3/2 scan electrodes 34 correspond to each other, the address electrodes 15 corresponding to each pixel 120 correspond to each other. ) And the scan electrode 34 satisfy the ratio of the following equation (1).

Number of address electrodes: Number of scan electrodes = 4: 3

In the embodiment shown in FIG. 1, four columns of pixels 120 are arranged along the x-axis direction, and four rows of pixels 120 are arranged along the y-axis direction, so that a total of 16 pixels 120 are disposed ( The sustain electrode Xn + 7 and the scan electrode Yn + 7 except the corresponding rows).

In this case, since two address electrodes 15 correspond to two columns of each pixel 120, a total of eight address electrodes 15 (Am + 1, ..., Am) correspond to a total of 16 pixels 120. +8) correspond to each other, and the scan electrodes 34 correspond to 3/2 per row of each pixel 120. Therefore, a total of six scan electrodes 34 (Yn + 1) correspond to 16 pixels 120 in total. , ..., Yn + 6). The sustain electrodes 32 (Xn + 1,..., Xn + 6) correspond to the scan electrodes 34 for each pixel 120, and six are disposed in a total of 16 pixels 120.

In this pixel arrangement, two adjacent subpixels 120G and 120B corresponding to the same address electrode 15 have phosphor layers of different colors. In addition, as described above, sub-pixels 120R, 120G, and 120B having phosphor layers of different colors may correspond to one address electrode 15.

Compared with the conventional plasma display panel illustrated in FIG. 4, when considering 4 x 4 pixels 120, that is, 16 pixels 120 in total, a total of 12 address electrodes are conventionally required. In this embodiment, only eight address electrodes 15 are needed. Therefore, while maintaining the same number of pixels, the first embodiment reduces the number of address electrodes 15 as compared with the prior art.

In this case, a total of four scan electrodes are conventionally required, whereas a total of six scan electrodes 34 are required in the first embodiment. Therefore, while maintaining the same number of pixels, the number of scan electrodes 34 is increased in comparison with the first embodiment.

That is, the plasma display panel 100 of the first embodiment reduces the number of address electrodes 15 by one third compared to the number of address electrodes in the related art, thereby facilitating the design of the terminal portion of the address electrode 15. .

For this reason, the power consumption of the address electrode 15 is reduced by 1/3 compared with the conventional power consumption. In addition, the peak power of one address element (for example, " Tape Carrier Package (TCP) ") that controls the address electrode 15 is reduced by 1/3 compared with the conventional one. Since the scanning element is cheaper than the address element, the overall circuit driving the panel is reduced due to the decrease of the address element despite the increase of the scanning element.

As described above, the number of address electrodes 15 can be reduced. However, when one address electrode 15 is used as a reference, subpixels of different colors are alternately positioned, so that the scan electrodes are expressed when a single vertical line (y-axis direction) is expressed. When scanning is performed in the order of (34) (that is, Yn + 1, Yn + 2, Yn + 3, Yn + 4 ...), the number of switching of the address electrode 15 increases. Since the increase in the switching frequency causes an increase in the address power consumption, a scan method for suppressing the change is required. This scanning method will be described in detail later in the description of FIG. 4.

The scan electrode 34 is connected to the scan electrode driver 200, the sustain electrode 32 is connected to the sustain electrode driver 300, and the address electrode 15 is connected to the address electrode driver 400.

The discharge cell to be turned on by the scan pulse applied to the scan electrode 34 according to the control signal of the scan electrode driver 200 and the address pulse applied to the address electrode 15 according to the control signal of the address electrode driver 400. 18) is selected.

A discharge cell selected by a sustain pulse applied to the scan electrode 34 according to the control signal of the scan electrode driver 200 and a sustain pulse applied to the sustain electrode 32 according to the control signal of the sustain electrode driver 300 ( 18) Implement this picture.

Scan electrodes 34 are connected to the scan electrode driver 200, and scan electrodes 34 disposed on discharge cells 18 of the same color are sequentially connected along the y-axis direction.

The scan electrodes 34 are connected to the scan electrode driver 200 in the order of skipping three in the y-axis direction. Accordingly, when the scan electrode driver 200 sequentially generates scan pulses, the discharge cells 18 of one color are sequentially selected based on each address electrode 15 by this connection, and then the next color of the next color is sequentially generated. Discharge cells 18 are selected.

The scan electrode driver 200 has a red scan electrode driver 210, a green scan electrode driver 220, based on one address electrode 15 among the discharge cells 18 of three colors. And a blue scan electrode driver 230.

The scan electrodes 34 (Yn + 1, Yn + 4, Yn + 7, ...) disposed in the red discharge cells 120R are sequentially connected to the red scan electrode driver 210.

The scan electrodes 34 (Yn + 2, Yn + 5, ...) disposed in the green discharge cells 120G are sequentially connected to the green scan electrode driver 220.

The scan electrodes 34 (Yn + 3, Yn + 6, ...) disposed in the blue discharge cells 120B are sequentially connected to the blue scan electrode driver 230.

In this way, when the discharge cells of each color are connected to the separate scan electrode drivers 210, 220, and 230 when the one address electrode is referred to, and scan pulses are sequentially applied in the connected order, the address electrodes 15 are used to express the vertical lines of a single color. ), It is possible to prevent an increase in the number of switching of the address element provided in the address electrode driver 400 applying an address pulse. As a result, it is possible to prevent the address power consumption from increasing.

When the scan electrodes 34 are connected to the scan electrode driver 200 as described above, the sustain electrode 32 is also preferably connected to the sustain electrode driver 300 as described above.

The sustain electrode driver 300 has a red sustain electrode driver 310, a green sustain electrode driver 320, based on one address electrode 15 of the discharge cells 18 of three colors. And a blue sustain electrode driver 330.

The sustain electrodes 32 (Xn + 1, Xn + 4, Xn + 7, ...) disposed in the red discharge cells 120R are sequentially connected to the red sustain electrode driver 310.

The sustain electrodes 32 (Xn + 2, Xn + 5, ...) disposed in the green discharge cells 120G are sequentially connected to the green scan electrode driver 320.

The sustain electrodes Xn + 3, Xn + 3, ... disposed in the blue discharge cells 120B are sequentially connected to the blue sustain electrode driver 330.

3 is a schematic structural diagram of a plasma display device according to a second embodiment of the present invention.

The second embodiment is substantially similar in configuration and effect to that of the first embodiment, and is the plane of the subpixels 220R, 220G, and 220B forming one pixel 220 in the plasma display panel 500. There is a difference in shape.

That is, in the second embodiment, the discharge cells 28 forming the subpixels 220R, 220G, and 220B are formed in a rectangular planar shape. This shows by way of example that the planar shape of the discharge cell 28 can be variously implemented.

4 is a diagram illustrating a scanning method in a plasma display device according to an embodiment of the present invention. In FIG. 4, only a waveform applied to some of the scan electrodes 34 in the address period is shown for convenience.

As described above, in the plasma display device according to the exemplary embodiment of the present invention, when the sub-pixels of different colors are alternately positioned based on one address electrode 15, a single vertical color line (y-axis direction) is expressed. When scanning is performed in the order of the scan electrodes 34 (that is, Yn + 1, Yn + 2, Yn + 3, Yn + 4 ...), the number of switching of the address electrodes 15 increases.

Therefore, as shown in FIG. 4, scan pulses are applied to all scan electrodes corresponding to one color discharge cell based on one address electrode, and then scan pulses are applied to scan electrodes corresponding to the next color discharge. .

First, in the first period T1 of the address period, scan pulses having a VscL voltage are sequentially applied to the scan electrodes Yn + 1, Yn + 4, Yn + 7. That is, based on one address electrode Am + 2, the scan electrodes Yn + 1, Yn + 4, and Yn + 7... Are disposed sequentially in the red discharge cells 120R or 220R. Apply a scan pulse.

Next, in the second period T2 of the address period, scan pulses having a VscL voltage are sequentially applied to the scan electrodes Yn + 2, Yn + 5, Yn + 8. That is, based on one address electrode Am + 2, the scan electrodes Yn + 2, Yn + 5, Yn + 8... Which are disposed in the green discharge cells 120G or 220G are sequentially formed. Apply a scan pulse.

Finally, in the third period T3 of the address period, scan pulses having a VscL voltage are sequentially applied to the scan electrodes Yn + 3, Yn + 6, Yn + 9. That is, based on one address electrode Am + 2, the scan electrodes Yn + 3, Yn + 6, Yn + 9... Are disposed in the blue discharge cells 120B or 220B in order. Apply a scan pulse.

Here, each scan electrode is maintained at a VscH voltage higher than the VscL voltage when no scan pulse is applied.

As described above, when scan pulses are continuously applied to the scan electrodes corresponding to the discharge cells of the same color based on one address electrode, the number of switching of the address element is reduced when expressing a single vertical line. The address power consumption can be prevented from increasing.

 On the other hand, in Fig. 4 is shown as a pulse falling in the negative direction for example as a scan pulse, it is obvious that other waveforms applied to the scan electrode may be applied to select the light emitting cells and non-light emitting cells in the address period. .

By reducing the number of address electrodes corresponding to each pixel, an increase in address power consumption accompanying a high resolution panel can be suppressed.

In addition, according to the plasma display device according to the present invention, by reducing the number of address elements connected to the address electrode, it is possible to reduce the price of the circuit for driving the panel as a whole.
