제2도는 본 고안에 따른 플라즈마 디스플레이 판넬의 단면도.2 is a cross-sectional view of the plasma display panel according to the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 애노드 전극 2 : 전면유리기판1: anode electrode 2: front glass substrate

3 : 보조전극 4 : 격벽3: auxiliary electrode 4: partition wall

5 : 캐소오드전극 6 : 배면유리기판5: cathode electrode 6: back glass substrate

본 고안은 기체 방전을 이용하여 표시하는 플라즈마 디스플레이 판넬(PDP)에 관한 것으로, 특히 애노드전극 사이에 보조전극을 사용한 플라즈마 디스플레이 판넬에 관한 것이다.The present invention relates to a plasma display panel (PDP) displayed by using a gas discharge, and more particularly to a plasma display panel using an auxiliary electrode between the anode electrode.

일반적으로 플라즈마 디스플레이 판넬(이하 PDP라 약칭함)은 상하부의 전극이 형성된 유리기판 사이에 개스를 봉입하여 전극에 인가된 전압에 의해 발생되는 개스방전을 이용한 표시소자이다.In general, a plasma display panel (hereinafter, abbreviated as PDP) is a display device using gas discharge generated by a voltage applied to an electrode by enclosing gas between glass substrates having upper and lower electrodes formed thereon.

종래의 PDP는 유리기판 상단에 저전압구동을 위한 점호(Keepalive)전극을 사용하여 프라이밍(Priming)효과를 얻었으나 이는 계조표시를 위한 라이징 타임의 개선에 한계가 있고, 또한 보조방전으로 인해 선택점과 비선택점의 콘트라스트가 저하되는 결점이 있었다.Conventional PDP has a priming effect by using a kelpal electrode for low voltage driving on the upper surface of the glass substrate, but it has a limitation in improving the rise time for gray scale display, and also due to the secondary discharge, There existed a fault which the contrast of a nonselective point falls.

따라서, 본 고안은 애노드전극 사이에 보조전극을 각 라인마다 하나씩 삽입하여, 보조전극과 캐소오드 전극에 인가한 전압에 의해 순간적으로 발생되는 하전입자와 여기원자로 애노즈 전극과 캐소오드 전극 사이에 가해지는 전압을 낮출 수 있고 또한 방전 라이징 타임을 빠르게 하여 계조 표시를 가능케 한 PDP를 제공하는데 그 목적이 있다.Therefore, according to the present invention, an auxiliary electrode is inserted between the anode electrodes, one for each line, and applied between the anode electrode and the cathode electrode as the charged particles and excitation atoms generated instantaneously by the voltage applied to the auxiliary electrode and the cathode electrode. It is an object of the present invention to provide a PDP that can lower the voltage and accelerate the discharge rising time to enable gray scale display.

다음은 첨부 도면에 의거하여 본 고안을 상세히 설명한다.Next, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 PDP의 사시도이고, 제2도는 PDP의 단면도이고, 2와 6은 전면과 배면유기 기판이고, 1은 애노드전극, 3은 보조전극, 4는 격벽 그리고 5는 캐소오드 전극이다.1 is a perspective view of a PDP according to the present invention, FIG. 2 is a sectional view of a PDP, 2 and 6 are front and rear organic substrates, 1 is an anode electrode, 3 is an auxiliary electrode, 4 is a partition electrode, and 5 is a cathode electrode. to be.

제2도에서, 배면 유리기판(6) 상에는 캐소오드전극(5)이 형성시키고, 전면 유리기판(2) 상에는 애노드 전극(1)과 보조전극(3)을 소정간격을 두고 형성시키며, 애노드 전극(1)과 보조전극(3)을 쌍으로 하여 셀마다 구분하도록 격벽(4)을 형성시킨다.In FIG. 2, the cathode electrode 5 is formed on the rear glass substrate 6, and the anode electrode 1 and the auxiliary electrode 3 are formed on the front glass substrate 2 at a predetermined interval, and the anode electrode is formed. The partition wall 4 is formed so as to distinguish each cell by pairing the (1) and the auxiliary electrode 3.

그리고, 상기의 보조전극(3)은 격벽(4)이 인쇄되는 소정부분까지 형성되게 하여 얼라인(align)문제로 발생하는 보조전극의 막힘을 방지할 수 있다.In addition, the auxiliary electrode 3 may be formed to a predetermined portion on which the barrier rib 4 is printed, thereby preventing clogging of the auxiliary electrode caused by an alignment problem.

이와 같이 전, 배면 유리기판(2)(6)사이에 개스를 봉입하여 형성된 PDP는 보조전극(3)으로 인해 프라이밍 효과를 갖는 하전 입자 및 여기원자의 생성을 쉽게 하고 이로써 저전압 구동 및 계조표시가 가능하다.Thus, the PDP formed by enclosing the gas between the front and rear glass substrates 2 and 6 facilitates the generation of charged particles and excitation atoms having a priming effect due to the auxiliary electrode 3, thereby enabling low voltage driving and gray scale display. It is possible.

상기의 보조전극의 구동방법을 설명하면, 우선 캐소오드전극(5)에 스캔 전압이 가해지고, 데이터가 입력되는 애노드전압이 판넬에 인가되기전 보조전극(3)에 펄스 전압을 인가하여 보조전극(3)과 캐소오드 전극(5)사이에 하전입자들이 형성되게 한다.Referring to the method of driving the auxiliary electrode, first, a scan voltage is applied to the cathode electrode 5, and a pulse voltage is applied to the auxiliary electrode 3 before the anode voltage to which data is input is applied to the panel. Charged particles are formed between (3) and the cathode electrode (5).

그리고 보조전극(3)에 인가되는 펄스전압이 강화되고 아룰러 애노드전압이 애노드전극(1)에 가해져서 스캔전압과 애노드전압에 의해 개스방전이 일어난다.In addition, the pulse voltage applied to the auxiliary electrode 3 is intensified, and the arranging anode voltage is applied to the anode electrode 1 so that gas discharge occurs by the scan voltage and the anode voltage.

이때 비 선택점에서 발생되는 하전입자들은 데이터 전압이 없어 곧 바로 소거되고, 선택점에서는 캐소오드 전극과 애노드 전극에 가해진 전압으로 보조전극에 의해 생성된 하전입자들이 개스방전에 사용된다.At this time, the charged particles generated at the non-selection point are immediately erased because there is no data voltage, and at the selected point, the charged particles generated by the auxiliary electrode are used to discharge the gas by the voltage applied to the cathode electrode and the anode electrode.

이상에서 설명한 바와 같이 본 고안에 의하면 보조전극의 사용으로 프라이밍 효과를 얻을 수 있고, 구동전압을 낮출 수 있으며, 또한 방전 라이징 타임을 빨리하여 계조표시를 가능케 하며 콘트라스트도 높힐 수 있다.As described above, according to the present invention, the priming effect can be obtained by using the auxiliary electrode, the driving voltage can be lowered, and the discharge rising time can be accelerated to enable gray scale display and the contrast can be increased.
