Description

플라즈마 디스플레이 패널의 전극{electrode of plasma display panel}Electrode of plasma display panel

본 발명은, 플라즈마 디스플레이 패널의 전극에 관한 것으로, 더 상세하게는 플라즈마 디스플레이 패널의 방전효율을 향상시켜 기능 향상 및 생산성 향상을 도모할 수 있는 플라즈마 디스플레이 패널의 전극에 관한 것이다.The present invention relates to an electrode of a plasma display panel, and more particularly, to an electrode of a plasma display panel capable of improving the discharge efficiency of the plasma display panel and improving the function and productivity.

도 1에는 종래의 플라즈마 디스플레이 패널(PDP)의 구성을 설명하기 위한 개략부분단면도가 도시되는 바, 도 1에서 그 플라즈마 디스플레이 패널은, X전극(3)과 Y전극(4)으로 전면 전극군을 형성하여 전면기판(1)에 형성되며, 그위에 유전층(6)이 형성된다. 또, 그 전면기판(1)의 대향측에는 후면기판(2)에 데이터전극으로서 어드레스전극(5)이 형성되고, 그 위에 유전층(7)이 형성되며, 격벽(8)사이에 형광체 패턴(9)이 형성된다.FIG. 1 shows a schematic partial cross-sectional view for explaining the structure of a conventional plasma display panel (PDP). In FIG. 1, the plasma display panel includes a front electrode group formed of an X electrode 3 and a Y electrode 4. Formed on the front substrate 1, on which the dielectric layer 6 is formed. On the opposite side of the front substrate 1, an address electrode 5 is formed on the rear substrate 2 as a data electrode, a dielectric layer 7 is formed thereon, and the phosphor pattern 9 is formed between the partitions 8. Is formed.

이러한 플라즈마 디스플레이 패널은, X전극(3) 및 Y전극(4)의 폭(a,b)가 동일하며, 서로 대칭으로 형성되어 있다.The plasma display panel has the same width a and b of the X electrode 3 and the Y electrode 4, and is formed symmetrically with each other.

이와 같이 구성되는 플라즈마 디스플레이장치의 구동방법은, 1프레임을 6개의 서브프레임으로 분할하고, 각 서브프레임은 서로 다른 유지기간이 설정하고, 각 서브프레임을 조합하여 영상화면의 계조를 표시하고, 각 서브프레임은 리셋(Reset)기간, 어드레스기간, 및 유지기간으로 분리된다. 리셋기간에는, 패널의 모든 셀의 방전조건을 균일화 또는 초기화하기 위해 공통접속된 X전극(3)에 쓰기펄스를 인가하여 모든 셀들을 전면 방전시키고, 다음에 모든 Y전극(4)들에 유지펄스를 인가하여 유지방전을 한 후, 공통접속된 X전극(3)에 소거펄스를 인가하여 유전체상에 축적된 벽전하를 소거한다. 어드레스 기간에는, 입력된 영상데이터에 따라 표시해야할 셀들을 지정하기 위해 어드레스 전극에 데이터 펄스가 인가되고, Y전극(4)에는 순차적으로 스캔펄스가 인가되어, 표시해야할 셀의 전면 유전층(6)상에 벽전하가 축적된다. 다음에 유지펄스를 X전극(3) 및 Y전극(4)에 교번으로 인가하여, 어드레스 기간에 지정된, 즉 벽전하가 축적된 셀만 유지방전을 한다.In the driving method of the plasma display apparatus configured as described above, one frame is divided into six subframes, each subframe is set to have a different retention period, and each subframe is combined to display the gray level of the video screen. The subframe is divided into a reset period, an address period, and a sustain period. In the reset period, in order to equalize or initialize the discharge conditions of all the cells of the panel, a write pulse is applied to the commonly connected X electrodes 3 to discharge all the cells entirely, and then the sustain pulses are applied to all the Y electrodes 4. After the sustain discharge is applied, an erase pulse is applied to the commonly connected X electrode 3 to erase the wall charges accumulated on the dielectric. In the address period, data pulses are applied to the address electrode to designate cells to be displayed according to the input image data, and scan pulses are sequentially applied to the Y electrode 4, so that the front dielectric layer 6 of the cell to be displayed is applied. Wall charges accumulate in the Next, the sustain pulse is alternately applied to the X electrode 3 and the Y electrode 4, so that only the cells designated in the address period, that is, the wall charges are accumulated, are sustain discharged.

상술된 1서브프레임의 표시동안에, 리셋(Reset)기간과 어드레스 기간에 어드레스전극(5)은 전면 전극군인 X전극(3) 및 Y전극(4)과 동일한 기준 준위로 그라운드 레벨(Ground Level)로 처리 되어 방전에 필요한 기입 및 소거를 원활하게 하기 위한 공간전하(Space Charge)와 벽전하(Wall Charge)를 생성하고 있다. 또한, 유지 기간에서는 어드레스전극(5)은 그라운드 레벨로 처리되어 있지 않고 하이-임피덴스(Hi-lmpedence)로 처리되어 있으며, 전면 전극군에 형성되는 공간전하로 어드레스전극(5)에 전압이 유기된다. 이는 편의상 플로팅(floating)된 어드레스 전압을 어드레스 유기전압이라 한다. 유지 방전시 그 어드레스 유기전압은, 그라운드 레벨로 처리하면, 유지 방전이 불안정성을 초래할 수도 있다. 따라서, 모든 면방전 구조에서는 하이 임퍼덴스(Hi-lmpedence)로 통상 처리하고 있다.During the display of the above one subframe, in the reset period and the address period, the address electrode 5 is brought to the ground level at the same reference level as the X electrode 3 and the Y electrode 4, which are the front electrode groups. The process generates space charges and wall charges to facilitate writing and erasing required for discharge. In the sustain period, the address electrode 5 is not treated at ground level but is treated with high-impedance, and voltage is induced to the address electrode 5 due to the space charge formed in the front electrode group. do. For convenience, the floating address voltage is called an address induced voltage. When the address induced voltage at the sustain discharge is processed at the ground level, the sustain discharge may cause instability. Therefore, in all surface discharge structures, it is normally processed by high-impedance (Hi-lmpedence).

상술한 구성의 종래의 플라즈마 디스플레이 패널은, 회로 구동시에 Y전극(4)이 어드레싱의 중요한 역할을 하고 X전극(3)은 보조하는 역활을 하는데 Y전극(4)의 어드레싱 제어가 어렵다는 결점이 있다.In the conventional plasma display panel having the above-described configuration, the Y electrode 4 plays an important role of addressing and the X electrode 3 plays a role in addressing the circuit, but the addressing control of the Y electrode 4 is difficult. .

또한, 기존의 대칭적 X전극(3) 및 Y전극(4)의 전극 구조로는 방전후 형성된 프림밍 파티클(Primming Particle)의 제어가 어렵고, 결과적으로 동특성 마진(Margin)이 떨어지는 결점이 있다.In addition, the electrode structures of the conventional symmetric X electrodes 3 and Y electrodes 4 are difficult to control the priming particles formed after the discharge, and as a result, there is a disadvantage in that the dynamic margin is reduced.

따라서, 본 발명은, 상술한 문제점들을 해결하기 위한 것으로, Y전극의 어드레싱 제어와 방전후 형성된 프림밍 파티클(Primming Particle)의 제어를 용이하게 하여 플라즈마 디스플레이 패널의 방전효율을 향상시킴으로써 기능 향상 및 생산성 향상을 도모할 수 있는 플라즈마 디스플레이 패널의 전극을 제공하는 데에 그 목적이 있다.Accordingly, the present invention is to solve the above problems, to facilitate the addressing control of the Y electrode and the control of the priming particles formed after discharge to improve the discharge efficiency of the plasma display panel to improve the function and productivity An object of the present invention is to provide an electrode of a plasma display panel that can be improved.
