Description

Dual type plasma display panel

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel, and more particularly, to a dual type plasma display panel having an improved structure to allow viewing by implementing images on both sides.

In general, a plasma display panel discharges a sealed gas between two substrates on which electrodes are formed, and causes a flat display device to excite a phosphor layer by ultraviolet rays, thereby implementing desired numbers, letters, or graphics. )to be.

The plasma display panel can be classified into a direct current type and an alternating current type according to a type of driving voltage applied to a discharge cell, for example, a discharge type, and can be classified into a counter discharge type and a surface discharge type according to the configuration of the electrodes.

The DC plasma display panel has a structure in which all electrodes are exposed to a discharge space, and charges are directly transferred between corresponding electrodes. On the other hand, in the AC plasma display panel, at least one electrode is embedded in the dielectric layer, and instead of direct charge transfer between the corresponding electrodes, ions and electrons generated by the discharge adhere to the surface of the dielectric layer so that the wall voltage is reduced. (wall voltage) is formed, and the discharge can be maintained by the sustaining voltage.

In the opposite discharge type plasma display panel, an address electrode and a sustain electrode are provided to face each pixel, and addressing discharge and sustain discharge are generated between the two electrodes. On the other hand, in the surface discharge plasma display panel, an address electrode and corresponding X and Y electrodes are provided for each unit pixel to generate addressing discharge and sustain discharge.

Referring to FIG. 1, in the conventional plasma display panel 100, a pair of X and Y electrodes 121 and 122 are disposed on the bottom surface of the front substrate 110 to be spaced apart from each other by a predetermined interval. Bus electrodes 123 are connected to edges of the 121 and 122. The X and Y electrodes 121 and 122 and the bus electrode 123 are buried by the front dielectric layer 130. The passivation layer 140 is coated on the front surface of the dielectric layer 130.

An address electrode 160 is formed on an upper surface of the rear substrate 150 disposed to face the front substrate 110, and the address electrode 160 is embedded by the rear dielectric layer 170. A partition wall 180 is formed on the rear dielectric layer 170 to prevent cross talk between adjacent discharge cells. Red, green, and blue phosphor layers 190 are formed for each discharge cell on the surface of the back dielectric layer 170 and the inner surface of the partition wall 180.

Meanwhile, a discharge gas including an inert gas is encapsulated in the combined inner space of the front and bottom substrates 110 and 150 to have a discharge region S.

The plasma display panel 100 having the above structure selects a discharge cell for emitting light by applying a signal to the Y electrode 122 and the address electrode 160, and alternates between the X and Y electrodes 121 and 122. By applying a signal to, a still image or moving picture can be viewed.

However, the conventional plasma display panel 100 has the following problems.

First, there is a limit as a high efficiency flat panel display.

The panel 100 has a structure in which a plurality of electrodes 121 to 123, a front dielectric layer 130, and a protective layer 140 are coated on a lower portion of the front substrate 110 corresponding to the discharge region. Therefore, visible light generated through the excitation of the ultraviolet ray and the phosphor layer 190 generated through the discharge passes through the front substrate 110 so that the transmittance of the brightness is less than 60%.

Second, the discharge start becomes difficult.

The initiation of the discharge is created in the gap between the X and Y electrodes 121 and 122. In other words, the discharge starts at the gap between the X and Y electrodes 121 and 122 in the entire discharge space. This allows the portion in which the plasma acting as the seed to be produced to be limited.

Third, the space utilization of discharge falls.

The discharge spreads around, but since it mainly spreads along the plane, the utilization of the entire discharge space is low. As such, the entire space for discharge cannot be effectively used.

Fourth, dual implementation is difficult.

Since the image can be implemented in only one direction, it is difficult to realize the consumer's desire when it is necessary to watch the image in both directions at the same time.

The present invention has been made to solve the above problems, and an object thereof is to provide a dual type plasma display panel having an improved structure such that a discharge electrode is formed along an edge of the discharge space.

The X and Y electrodes 371 and 372 are vertically disposed between the first and second partitions 330 and 350. In addition, since the X and Y electrodes 371 and 372 are not electrically connected, independent voltages are applied during driving. The X and Y electrodes 371 and 372 have a rectangular shape for each discharge space between the first and second partitions 330 and 350 arranged in a lattice shape.

In addition, the address electrode 380 is disposed in a direction parallel to the Y direction, which is a direction intersecting with the X and Y electrodes 371 and 372, and similarly adjacent to the X and Y electrodes 371 and 372. The same voltage is applied by integrally connecting between the electrodes arranged in the space.

Accordingly, the address electrode 380 has a ladder shape in which quadrangles are continuously arranged along the circumference of the discharge space in a direction parallel to the Y direction.

The X and Y electrodes 371 and 372 and the address electrode 380 disposed therebetween are embedded by the dielectric wall 390. The dielectric wall 390 is made of a dielectric material mainly composed of frit glass.

The dielectric wall 390 is formed between the first and second partitions 330 and 350 corresponding thereto.

The passivation layer 399 is generally applied along the inner surface of the dielectric wall 390. The passivation layer 399 is not limited to any one of carbon-based materials, such as carbon nanotubes, may be formed in order to maximize secondary electron emission.

On the other hand, in the discharge space S, the discharge surface is increased and the discharge area can be enlarged due to the above-described structure, so that the amount of plasma is increased, so that even when a high concentration, for example, 10 volume percent of xenon gas is used as the discharge gas, low-voltage driving is performed. This becomes possible, and the light emission efficiency can be improved significantly.

As such, in the plasma display panel 300 according to the first embodiment of the present invention, the first and second barrier ribs 330 and 350 are disposed on opposite surfaces of the first substrate 310 and the second substrate 320. The first and second phosphor layers 340 and 360 are coated on inner walls of the first and second partitions 330 and 350.

The operation of the plasma display panel 300 having the above structure will be described below.

First, when a predetermined address voltage is applied between the address electrode 380 and the Y electrode 372 from an external power source, the discharge space S to be emitted is selected. Wall charges are accumulated on the Y electrode 372 of the selected discharge space S.

Subsequently, when a voltage of “+” is applied to the X electrode 371 and a voltage higher than this is applied to the Y electrode 372, the wall is caused by the voltage difference applied between the X and Y electrodes 371 and 372. The charge will move.

The movement of the wall charges generates a plasma by colliding with the discharge gas atoms in the discharge space S, and the discharge is adjacent to the X electrode 371 and the Y electrode 372 where a relatively strong electric field is formed. More likely to occur from the part.

Accordingly, since the X electrode 371 and the Y electrode 372 are formed along the side surface of the discharge space S, the discharge is compared with the prior art in which a close portion of the discharge electrode is formed only on the upper surface of the discharge space S. FIG. The likelihood of this is greatly increased.

Subsequently, if the voltage difference between the X electrode 371 and the Y electrode 372 is still sufficiently large as time passes, the electric field formed between the two electrodes 371 and 372 is gradually loaded, thereby discharging the discharge. It spreads to the entire space S.

Since the discharge in the present embodiment is generated in a ring type at four sides of the discharge space S and diffuses to the center of the discharge space S, the conventional discharge is generated at one upper surface of the discharge space S and is centered. The diffusion range is greatly increased than in the case of diffusion.

In addition, since the plasma generated by the discharge is formed in a ring type along the side of the discharge space (S) and diffused to the center portion, the volume is greatly increased, the amount of visible light is greatly increased, the plasma is discharge space (S) By concentrating on the center portion of the space charge can be utilized to enable low-voltage driving, it is possible to obtain the effect of improving the luminous efficiency.

In addition, since the plasma is concentrated in the center portion of the discharge space S, and the electric fields by the X and Y electrodes 371 and 372 are formed on both sides of the plasma, the charge is concentrated in the center portion of the discharge space S so that Ion sputtering to the first and second phosphor layers 340 and 360 can be prevented at the source.

If the voltage difference between the X and Y electrodes 371 and 372 is lower than the discharge voltage after the discharge is formed in this manner, the discharge no longer occurs, and the space charge and the wall charge are formed in the discharge space S. do. At this time, if the polarities of the voltages applied to the X and Y electrodes 371 and 372 are reversed, the discharge is generated again with the help of wall charges. If the polarities of the X and Y electrodes 371 and 372 are immediately changed, the first discharge process is repeated. The discharge is stably generated while repeating this process.

Color display as the fluorescent material of the first phosphor layer 340 on the first substrate 310 and the second phosphor layer 360 on the second substrate 320 is excited by the ultraviolet rays generated through the above process. In this way, the implemented image can be viewed simultaneously in both directions.
