The present invention relates to a plasma display panel, and more particularly, to a plasma display panel capable of increasing brightness and efficiency.

Recently, a plasma display panel, which has been attracting attention as a replacement for a conventional cathode ray tube display device, uses an image of visible light generated by exciting a phosphor of vacuum ultraviolet rays emitted from a plasma obtained through gas discharge. As a device for realizing, a self-luminous device such as a CRT has high color reproducibility, and can realize a very large screen with a thickness of only 10 cm or less, which has attracted attention as a TV and an industrial flat panel display.

Referring to FIG. 1, the three-electrode AC surface discharge plasma display panel is vertically spaced apart from the front substrate 11 including the common sustain electrode 13 and the scan sustain electrode 14 on the same plane, at a predetermined distance therefrom. It consists of a back substrate 21 including an address electrode 22 extending in the direction, between which a discharge gas (not shown) made of inert gas is enclosed.

In this plasma display panel, discharge is determined by the discharge of the scan electrode 14 and the address electrode 22 connected to each line and independently controlled, and the sustain discharge displaying the screen is determined by the sustain electrode located on the same plane. 13) and the scan electrode 14.

2 and 3 are plan views illustrating pixel and electrode arrays of a conventional plasma display panel. 2 illustrates a conventional plasma display panel having a stripe-type barrier rib structure, and FIG. 3 illustrates a plasma display panel having a delta-type barrier rib structure.

As shown in FIG. 2, in the plasma display panel having a stripe-type partition wall structure, the discharge cells 40 form a discharge gap and face each other the common sustain electrodes Xn,..., Xn + 3 and the scan electrodes. It is formed between (Yn, ..., Yn + 3).

One pixel 41 includes red, green, and blue discharge cells 41R, 41G, and 41B adjacent to each other, that is, three subpixels. At this time, the address electrodes 22 are formed to pass through each of the discharge cells constituting one pixel 41.

Therefore, as shown, in consideration of the 16 pixels 41, all three address electrodes 22 (Am, Am + 1, ... Am + 11) are required, three for each pixel 41. Done.

However, as the plasma display panel develops in a trend toward higher resolution, when the discharge cells 41R, 41G, and 41B are highly integrated, the address electrodes 22 passing through the discharge cells 41R, 41G, and 41B become closer to each other. do.

At this time, the address electrodes 22 are formed to pass through each of the discharge cells 41R, 41G, 41B constituting one pixel 41.

Also in this case, considering the sixteen pixels 41, all three address electrodes 22 (Am, Am + 1, ... Am + 11), three for each pixel 41, It is necessary.

However, as the plasma display panel gradually develops into a higher resolution, when the discharge cells 41R, 41G, and 41B are highly integrated, the address electrodes 22 passing through the discharge cells 41R, 41G, and 41B become closer. You lose.

As a result, the capacitance (C) value between the neighboring address electrodes 22 increases, which inevitably increases energy (= CV ² f) consumption.

4 is an exploded perspective view partially showing a plasma display panel according to a first embodiment of the present invention, and FIG. 5 is a plan view showing a part of pixel and electrode arrays of the plasma display panel shown in FIG.

4 and 5, the plasma display panel 110 includes a first substrate 11 and a second substrate 121, sustain electrode pairs 112, a first dielectric layer 115, and a protection circuit. And a layer (not shown), address electrodes 122, second dielectric layer 125, barrier ribs 130, phosphor layer 126, and discharge gas (not shown).

The plasma display panel 110 includes a first substrate 110 and a second substrate 120 spaced apart from each other and disposed to face each other. The first substrate 110 is generally made of a material having excellent light transmittance mainly containing glass. However, the first substrate 110 may be colored in order to reduce reflection brightness and improve clear room contrast. In addition, the first substrate 120 defines a plurality of discharge cells 140 between the second substrate 110 and the second substrate 110. The second substrate 120 may be made of glass and may be colored.

In the plasma display panel 110, the sustain electrode pairs 112 are disposed in parallel on the first substrate 111 opposite to the second substrate 121 at predetermined intervals along the first direction (the x-axis direction of the drawing). have. Each sustain electrode pair 112 includes an X electrode 113 and a Y electrode 114, and the X electrode 113 and the Y electrode 114 correspond to each other in the discharge cell 140 to form a discharge gap. And cause plasma discharge. In addition, the X electrode 113 and the Y electrode 114 are alternately arranged along the y-axis direction.

Each of the X electrode 113 and the Y electrode 114 covers the bus electrodes 113a and 114a formed on the first substrate 111 in the x-axis direction and covers the bus electrodes 113a and 114a. It includes a transparent electrode 113b (114b) formed in a structure.

The bus electrodes 113a and 114a may be made of a metal material having excellent electrical conductivity. The bus electrodes 113a and 114a may be formed by minimizing the line width as much as possible to secure conduction in order to minimize shielding of visible light generated by the discharge cells 140 when driving the plasma display panel.

The transparent electrodes 113b and 114b are made of a transparent material such as indium tin oxide (ITO), and are formed to extend in the x-axis direction together with the bus electrodes 113a and 114a. Accordingly, in one discharge cell 140, a pair of transparent electrodes 113b and 114b are disposed to face each other with an interval therebetween.

The first dielectric layer 115 is formed on the entire surface of the first substrate 111 while covering the X electrode 113 and the Y electrode 114 on the first substrate 111 of the plasma display panel 110. The first dielectric 115 induces charge while preventing direct damage to adjacent X electrodes 113 and Y electrodes 114 by directly colliding with adjacent X electrodes 113 and Y electrodes 114 during discharge. And a dielectric material capable of accumulating wall charges. Examples of such dielectrics include PbO, B 2 O 3, and SiO 2.

In addition, a protective layer (not shown) may be formed on the first dielectric layer 115. The protective layer prevents the cations and the electrons from colliding with the first dielectric layer 115 during the discharge to damage the first dielectric layer 115, and discharges a lot of secondary electrons during the discharge to lower the discharge voltage. The protective layer may be formed by depositing magnesium oxide (MgO) on the first dielectric layer.

On the second substrate 121 facing the first substrate 11, the address electrodes 122 extend in the first direction (y-axis direction in the drawing), respectively, and the second direction (x-axis direction in the drawing) is formed. Are arranged side by side. The address electrodes 122 are disposed to pass below each discharge cell 140 (that is, between the rear substrate and the partition layer).

The address electrodes 122 are intended to cause an address discharge to facilitate sustain discharge between the X electrodes 113 and the Y electrodes 114, and more specifically, serve to lower a voltage for generating a discharge. The address discharge is a discharge occurring between the Y electrodes 114 and the address electrodes 122. When the address discharge is completed, cations are accumulated on the Y electrodes 114 and electrons are accumulated on the X electrode 113 side. As a result, the sustain discharge between the X electrodes 113 and the Y electrodes 114 becomes easier.

In the present invention, two address electrodes 122 are disposed on the basis of one pixel 141, and four pixels 141 in the x-axis direction and four pixels 141 in the y-axis direction, that is, all 16 Eight address electrodes 122 are disposed based on the four pixels 141.

In addition, the second dielectric layer 125 is formed on the entire surface of the rear substrate 121 while covering the address electrodes 122. Therefore, the address electrodes 122 are disposed under the layer formed by the barrier rib 130. The second dielectric layer 125 is formed of a dielectric that can induce charge while preventing cations or electrons from damaging the address electrodes 122 during discharge. Such dielectrics include PbO, B 2 O 3, and SiO 2.

In the plasma display panel 110, a partition wall 130 partitioning the plurality of discharge cells 140 is disposed between the first substrate 110 and the second substrate 120. According to the present invention, three subpixels (subpixels 141R, 141G, and 141B) generating red, green, and blue visible light each have discharge cells 140, and these discharge cells 1401 are partitioned by partition walls. .

Since the planar shape of each of the subpixels 141R, 141G, and 141B is substantially hexagonal, the partition wall 130 partitioning the subpixels 141R, 141G, and 141B also has a hexagonal shape. Is formed. Therefore, the discharge cells 140 of each of the subpixels 141R, 141G, and 141B have a hexagonal box shape with an upper portion opened.

On the second dielectric layer between the partition walls 130 partitioning the discharge cells 140 and on the side surfaces of the partition walls 130, sub-pixels corresponding to green and blue visible light, respectively, correspond to red, green and blue colors. Phosphor layer 126 is formed, respectively. The phosphor layers 126 have a component for generating visible light by receiving ultraviolet rays, and the red light emitting phosphors formed in the red discharge cells 141R include phosphors such as Y (V, P) O 4: Eu, and green. The green light emitting superlayers formed on the discharge cells 141G include phosphors such as Zn 2 SiO 4: Mn, and the blue light emitting phosphor layers formed on the blue discharge cells 141B include phosphors such as BAM: Eu.

 In addition, the discharge cells 140 are filled with a discharge gas in which xenon (Xe), neon (Ne), and the like are mixed. In the state in which the discharge gas is filled, the first and second substrates are sealed to each other by a sealing member such as frit glass formed at the edges of the first and second substrates 111 and 121.

The arrangement of the pixel and the electrode according to the present embodiment will be described in detail with reference to FIG.

Two address electrodes 122 correspond to each pixel 141 including subpixels 141R, 141G, and 141B that generate red, green, and blue visible light, respectively. That is, the two discharge cells 140 among the subpixels 141R, 141G, and 141B are arranged side by side adjacent to each other in the y-axis direction. Two scan electrodes 114 correspond to the one pixel 141.

In more detail, the pixel and electrode arrangement of the present embodiment will be described in detail with reference to two neighboring seven in the y-axis direction, and the two discharge cells 140 neighboring in the y-axis direction will be described. The two subpixels 141G and 141B formed correspond to one address electrode 122, and the subpixel 141R formed of the other discharge cell 140 corresponds to the other address electrode 122. That is, the subpixels 141G and 141B of the two discharge cells 140 corresponding to the same address electrode 122 have the phosphor layer 126 that generates visible light having different colors.

In addition, the two subpixels 141R and 141B formed of two discharge cells 140 neighboring each other in the x-axis direction correspond to one Y electrode 114 (Yn + 3), and the other one discharge cell ( The subpixel 141G formed of 140 corresponds to the other Y electrode 114 (Yn + 2). That is, the two discharge cells 140 corresponding to one Y electrode 114 (Yn + 3) have a phosphor layer 126 that generates visible light of different colors.

One pixel 141 corresponding to these Y electrodes 114 (Yn + 2) (Yn + 3) also corresponds to the X electrode 113 (Xn + 3) (Xn + 4). The X electrodes 113 (Xn + 3) (Xn + 4) and the Y electrodes 114 (Yn + 2) (Yn + 3) face each other in one pixel 141. The arrangement of the X electrode 113 and the Y electrode 114 corresponding to the pixel 141 may be set as described above or differently according to the selection of the pixels 141 repeatedly arranged.

In the present embodiment, each of the discharge cells 140 constituting each of the subpixels 141R, 141G, and 141B is arranged in a hexagonal plane shape. Therefore, these discharge cells 140 form a boundary by sides in six directions. Therefore, the extension line of the boundary of the pair of neighboring discharge cells 140 along the longitudinal direction (y-axis direction of the drawing) of the address electrode 122 has a direction crossing the address electrode 122 (x-axis direction of the drawing). As a result, it passes through the center of the adjacent discharge cell 140.

According to the arrangement of the pixel and the electrode according to the present embodiment described above, the Y electrode 114 (Yn + 3) passes through two subpixels 141R and 141B neighboring in the x-axis direction in one pixel 141. In addition, a common voltage is applied, and another Y electrode 114 (Yn + 2) applies a voltage while passing through one subpixel 141G in the same pixel 141. In addition, the Y electrode 114 (Yn + 2) passes the two subpixels 141G and 141B of the other pixels 141 neighboring in the x-axis direction and applies the same common voltage as described above.

In addition, the X electrode 113 (Xn + 4) faces the Y electrode Yn + 3 and applies a voltage corresponding to one subpixel 120B in one pixel 141. In addition, the X electrode 113 (Xn + 4) passes the two sub-pixels 141R and 141G of other pixels 141 neighboring in the x-axis direction and applies the same common voltage as described above. The other X electrode 113 (Xn + 3) applies a common voltage to the other two subpixels 141R and 141G in one pixel 141. The X electrode 113 (Xn + 3) faces the Y electrode 114 (Yn + 3) and the other Y electrode 114 (Yn + 2) on both sides of the y-axis direction.

As a result, the Y electrodes 114 and the X electrodes 113 are alternately arranged along the longitudinal direction (y-axis direction) of the address electrode 122 to control the driving of the pair of discharge cells 140, respectively. .

Referring to this as a reference to one pixel 141, two address electrodes 122 are arranged, and considering the four pixels 141 in the x-axis direction and the four pixels 141 in the y-axis direction, There are eight address electrodes 122 passing through the sixteen pixels 141.

That is, the plasma display panel of the first embodiment reduces the number of address electrodes 122 by one third compared to the conventional method, thereby facilitating the design of the terminal portion of the address electrode 122. As a result, the power consumption of the address electrode 122 is reduced by 1/3 compared with the conventional power consumption. In addition, the peak power of one address element controlling the address electrode 122 is reduced by 1/3 compared with the conventional one. In addition, the cost of the entire circuit for driving the panel is reduced due to the reduction in the address element, which is more expensive than the scanning element.

The driving method of the plasma display panel of the present invention by the electrode arrangement as described above is as follows.

First, an address discharge occurs by applying an address voltage between the address electrodes 122 and the Y electrodes 114, and as a result of the address discharge, the discharge cell 140 in which the sustain discharge occurs is selected. Then, when a sustain voltage is applied between the X electrodes 113 and the Y electrodes 114 of the selected discharge cells 140, the cations and the X electrodes 113 accumulated on the Y electrodes 114 side. Electrons accumulated on the side cause sustain discharge, and then a continuous discharge is generated as voltage pulses applied to the X electrodes 113 and the Y electrodes 114 are alternated. As the energy level of the discharge gas excited by this sustain discharge is lowered, visible light is emitted, and the emitted visible light constitutes an image.

6 and 7 show pixel and electrode shapes of the plasma display panel according to the second embodiment of the present invention.

FIG. 6 is a plan view showing the electrode shape of the plasma display panel according to the second embodiment of the present invention, and FIG. 7 is a plan view showing the pixel arrangement of the plasma display panel having the electrode shape shown in FIG. The plasma display panel shown in FIGS. 6 and 7 has a structure similar to that of the plasma display panel shown in FIG. 4 except for an electrode shape and an electrode driving method. It will be described in detail below.

6 and 7, in the plasma display panel according to the second embodiment of the present invention, subpixels emitting red, green, and blue visible light, which form one pixel, form hexagonal discharge cells and are formed by hexagonal partition walls. It is partitioned. Each address corresponds to two address electrodes as in the first embodiment. That is, two of the subpixels are adjacently arranged side by side in the longitudinal direction of the discharge cells.

However, the sustain electrodes protruding into the discharge cell space are out of the center of the discharge cell and have a unique shape in which the longitudinal center axis of the discharge cell does not coincide with the center axis of the discharge cell.

When the plasma display panel is discharged, when the distance of the discharge path is increased, more charged particles are formed than in the related art, thereby improving discharge efficiency of the plasma display panel and achieving high brightness. However, while the first embodiment of the present invention reduces the number of address lines per cell compared to the conventional delta structure, it is possible to reduce the consumption efficiency due to the reduction of the address power. Therefore, the discharge path is shortened in the discharge space by the shorter vertical axis, which causes a decrease in efficiency.

In the plasma display panel according to the second embodiment of the present invention, the discharge path can be made longer by disposing the vertical center axis of the cell and the vertical center axis of the sustain electrode while keeping the number of address lines per cell two. have. Accordingly, since many charged particles are generated, the discharge efficiency of the plasma display panel may be improved and high brightness may be achieved.

The sustain electrode of the shape protruding into the discharge cell according to the second embodiment can achieve high luminance by a transparent electrode such as ITO.

In addition, the present invention can achieve high brightness and high discharge efficiency by maximizing the length of the discharge path when the direction in which the transparent electrodes face each other is parallel to one direction of the diagonal direction of the discharge cell. In addition, the electrode structure according to the present embodiment can increase the voltage margin by maximizing the electrode area of the facing portion.

In addition, the present invention may include a bus electrode having good electrical conductivity in order to improve efficiency reduction by a transparent electrode having high resistance, such as ITO.

The X and Y electrodes of the plasma display panel according to the second embodiment of the present invention are disposed on the partition wall along the partition wall partitioning each discharge cell continuously in an equal area between adjacent discharge cells. This represents a so-called ALIS drive electrode arrangement that visually divides the odd and even lines of an AC plasma display panel to perform an alternate lighting surface method.

According to the ALIS driving method, more display areas can be obtained with the same display electrode as compared with the non-ALIS driving method. However, the present invention optimizes the discharge path between the pair of sustain electrodes. It can be applied to both the ALIS drive system and the ALIS drive system as in the second embodiment.

8 to 10 are plan views illustrating pixel arrays and electrode shapes of plasma display panels according to still another exemplary embodiment of the present invention.

8 is a plan view showing the pixel and electrode shapes of the plasma display panel according to the third embodiment of the present invention.

Referring to FIG. 8, two address lines are disposed in one pixel including red, green, and blue subpixels. In addition, as in the second embodiment, the X and Y electrodes are disposed on the partition wall along the partition wall partitioning each discharge cell continuously in an equal area between adjacent discharge cells, and the odd and even lines are provided. This is an ALIS-driven electrode arrangement that visually divides the light into an alternate lighting surface method.

However, the point where the shape of the transparent electrode is triangular is different from the point where the discharge cell is square. This shows that the planar shape of the discharge cell can be variously implemented by way of example, and the shape of the transparent electrode does not coincide with the longitudinal center axis of the cell and the vertical center axis of the transparent electrode. It can be shown that it can be implemented. In the structure according to the present embodiment, it is possible to increase the voltage margin by reducing the area of the electrode, reducing the reactive power consumption consumed in the panel, and increasing the area of the facing electrode portion contributing to the discharge.

9 is a plan view showing the pixel and electrode shapes of the plasma display panel according to the fourth embodiment of the present invention.

Referring to FIG. 9, two address lines are disposed in one pixel including red, green, and blue subpixels. The X and Y electrodes are arranged in a non-ALIS driving method as in the first embodiment. That is, each of the X and Y electrodes is not disposed along the partition walls of the discharge cells forming the subpixels, but is alternately arranged in parallel in the horizontal direction.

However, the square sustain electrodes are arranged on both edges of the discharge cells, and coincide with one direction in the diagonal direction of the discharge cells facing the cells. This shows that the planar shape of the discharge cell can be variously implemented, and various shapes that lengthen the discharge path can be realized by making the vertical center axis and the vertical center axis viewed by the transparent electrode do not coincide. To show.

10 is a plan view showing the pixel and electrode shapes of the plasma display panel according to the fifth embodiment of the present invention.

Referring to FIG. 10, two address lines are disposed in one pixel formed of red, green, and blue subpixels, and the first direction of the rectangular transparent electrode is parallel to one of the diagonal lines of the discharge cell. Same as the fourth embodiment.

The X and Y electrodes are arranged in a non-ALIS driving method as in the first embodiment. That is, each of the X and Y electrodes is not disposed along the partition walls of the discharge cells forming the subpixels, but is alternately arranged in parallel in the horizontal direction.

 However, the bus electrodes of each electrode can be disposed on the partition wall to lower the discharge voltage and contribute to the improvement of the aperture ratio, thereby improving the discharge efficiency as a whole.

As described above, according to the plasma display panel according to the present invention, two address lines correspond to one pixel to reduce the power consumption of the address power, and the vertical center axis of the discharge cell and the vertical center axis of the sustain electrode By disposing the electrodes so as not to coincide, the luminance and the discharge efficiency can be increased.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
