Abstract

본 고안은 개선된 PDP를 개시한다.The present invention discloses an improved PDP.

종래 발전형 PDP는 화이트밸런스나 고휘도 달성이 곤란했던 바, 본 고안에서는 균일한 간격의 스트라이프형 화점에 어느 한 화점을 2개 배열하여 4개의 화점스트라이프로 화소를 구성함으로써 제조가 용이하고 화이트밸런스 달성이 용이한 PDP를 구현한다.In the conventional power generation type PDP, it was difficult to achieve white balance or high brightness. In the present invention, two pixels are arranged in a stripe-type flash point with uniform intervals, so that the pixels are composed of four dot stripe strips, which are easy to manufacture and achieve white balance. Implement this easy PDP.

본 고안은 플라즈마 표시소자(PDP; Plasma Display Panel)에 관한 것이다.The present invention relates to a plasma display panel (PDP).

기체방전현상을 화상표시에 이용한 PDP의 가장 기본적인 구성은 두기판에 서로 교차 대향하는 전극을 배열하여 매트릭스(matrix)방식으로 구동하는 직류(DC)형 PDP인데, DC형 PDP는 선택시 방전의 개시가 지연되고 비선태시 방전이 유지되지 못하므로 이의 보완을 위해 여러 가지 방식의 PDP가 출현하였다.The most basic configuration of the PDP using the gas discharge phenomenon for image display is a direct current (DC) type PDP which operates in a matrix manner by arranging electrodes opposite to each other on two substrates. The DC type PDP starts discharge when selected. Since the delay and non-selective discharge are not maintained, various types of PDPs have appeared to compensate for this.

이러한 PDP중 가장 먼저 칼라 PDP를 실용화한 구성이 제 1 도 (a),(b)에 도시된 바와 같은 일본 NHK의 밭 "전(田)"형 PDP이다.Among the PDPs, the first use of the color PDP is a field "all" type PDP of Japanese NHK as shown in Figs. 1 (a) and (b).

밭전형 PDP는 도시된 바와 같이 각각 격벽(B1, B2)으로 구획된 2열의 화소마다 보조방전공간(V2)을 형성하여 보조전극(S)을 배열하고, 보조방전공간(V2)과 화소간의 격벽(B2)에 전하공급구멍(H)을 형성하여, 화소의 방전공간(V1)에 전하를 공급함으로써 전극(E1, E2)간의 주(主) 방전을 촉진하게 된다. 나머지 부호 P1, P2 는 전면 및 배면기판이다.The field-type PDP forms an auxiliary discharge space V2 for each of two rows of pixels partitioned by partitions B1 and B2 as shown in the drawing, to arrange the auxiliary electrodes S, and to partition the auxiliary discharge space V2 and the pixels. The charge supply hole H is formed in (B2), and the electric charge is supplied to the discharge space V1 of the pixel to promote the main discharge between the electrodes E1 and E2. The remaining symbols P1 and P2 are the front and back substrates.

그런데 이러한 밭전형 PDP는 화소가 제 2 도에 도시된 바와 같이 각 화소가 4개의 화점(R, G, B)가 모인 클러스터(cluster)로 구성될 수밖에 없게 되는 바, 이는 화소배열에 많은 문제를 야기한다.However, such a field-type PDP is forced to be composed of a cluster of four pixels (R, G, and B), with each pixel as shown in FIG. Cause.

즉 고유발광색을 가지는 화점이 R, G, B 3개이므로 4개의 화점 중 어느 하나가 남게 되는데, 여분의 화점에 흑색층을 형성하여 컨트라스트를 향상시키는 기술이 제안된 바 있으나 이는 화면 휘도를 저하시키는 문제가 있다.That is, since there are three R, G, and B dots having intrinsic luminescence colors, any one of the four dots remains. A technique for improving contrast by forming a black layer on the extra dots has been proposed. there is a problem.

한편 각 화점(R, G, B)의 형광층을 구성하는 형광체는 서로 발광강도가 동일하지 않은데 특히 B 형광체의 발광강도가 낮다. 따라서 도시된 바와 같이 B 화점을 2개 배열하는 구성도 사용되고 있으나, 이 경우는 화면의 화이트 밸런스(white balance)를 맞추기 어려워 색재현성이 불량한 문제가 야기된다.On the other hand, the phosphors constituting the fluorescent layers of each of the flash points (R, G, B) do not have the same emission intensity with each other, in particular, the emission intensity of the B phosphor is low. Therefore, a configuration in which two B dots are arranged as shown is used, but in this case, it is difficult to match the white balance of the screen, which causes a problem of poor color reproducibility.

이와 같은 문제를 해결하기 위해 본원인은 제 3 도 (a),(b)와 같이 각 화점(R, G, B)의 면적을 서로 달리한 화소배열을 가지는 PDP들을 제안한 바 있다.In order to solve such a problem, the present inventors have proposed PDPs having pixel arrays having different areas of each of the flash points R, G, and B, as shown in FIGS. 3A and 3B.

그러나 이들은 각 화점을 구획하는 격벽과 전극간의 간격이 서로 달라지게 되므로 제작이 번잡해지는 문제가 있다.However, they have a problem that manufacturing is complicated because the distance between the partition wall and the electrode partitioning each fire point is different from each other.

이에 따라 본 고안의 목적은 화이트 밸런스의 달성이 용이하고 제작도 용이한 PDP를 제공하는 것이다.Accordingly, an object of the present invention is to provide a PDP that is easy to achieve white balance and easy to manufacture.

상술한 목적의 달성을 위해 본 고안에 의한 PDP는 R, G, B 화점이 모여 화소를 구성하는 PDP에 있어서, R, G, B 화점이 모여 화소를 구성하는 PDP에 있어서, 각 화점이 스트라이프(stripe)형으로 구성되고, 어느 한 종류의 화점이 2개 배열되어 4개의 화점 스트라이프가 한 화소를 구성하게 되는 것을 특징으로 한다.In order to achieve the above object, a PDP according to the present invention is a PDP in which R, G, and B dots are gathered to form a pixel. stripe), and one kind of two dots are arranged so that four dot stripes constitute one pixel.

어라한 구성에 의하면 격벽간격이 일정해지므로 제조가 용이해지고, 한 종류의화점이 2개 배열되더라도 연속되는 것이 아니므로 화이트 밸런스의 달성이 용이해지게 된다.According to such an arrangement, the partition wall spacing becomes constant, so that the production is easy, and even if two kinds of flash points are arranged, it is not continuous, so that the achievement of the white balance becomes easy.

이하 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제 4 도에서, 본 고안 PDP의 각 화소를 구성하는 R, G, B 화점들은 각각 균일한 간격의 스트라이프로 구성되고, 어느 한 종류의 화점, 예를 들어 발광강도가 낮은 B 화점이 2개 배열되어 4개의 화점 스트라이프(R, B, G, B)가 한 화소를 구성하게 된다.In FIG. 4, R, G, and B dots constituting each pixel of the PDP of the present invention are each composed of stripes of uniform intervals, and one kind of dots, for example, two B dots having low luminous intensity are arranged. Four dot stripes R, B, G, and B constitute one pixel.

이때 2개 배열되는 화점(B)은 연속되지 않고 다른 화점(R 또는 G)을 사이에 두고 분리되는 것이 바람직하다.At this time, it is preferable that the two firing points B arranged are not continuous but separated from each other with a different firing point R or G therebetween.

이를 실제 PDP 구조로 구현한 구성을 제 5 도에 도시한 바, 각 화점 스트라이프(R, B, G, B)들은 격벽(B1)으로 구획되어 화소(X1, X2, …)를 연속적으로 구성하게 된다.As shown in FIG. 5, a configuration in which the actual PDP structure is implemented, each of the dot stripes R, B, G, and B are divided into partitions B1 to continuously configure the pixels X1, X2,... do.

여기서 2개 중복된 화점(B)의 전극(E2)들은 커먼(common)접속되어 동시에 구동전압이 인가된다.Here, the electrodes E2 of the two overlapping flash points B are commonly connected and a driving voltage is applied at the same time.

이와 같은 구성에 의하면 각 화점(R, G, B)과 화소들을 구획하는 격벽(B1)이 균일한 간격으로 형성될 수 있으며, 이에 따라 전극(E2)도 균일한 간격으로 형성될 수 있어 제조가 용이해진다.According to such a configuration, each of the fire points R, G, and B and the partition wall B1 partitioning the pixels may be formed at uniform intervals, and accordingly, the electrode E2 may be formed at uniform intervals, thereby making It becomes easy.

한편 이러한 구성에는 각 화소에 B 화점이 2개씩 위치하게 되나 이들이 연속된 것이 아니라 다른 화점(G)이 중간에 끼어 분리되어 있으므로 그 발광강도는 연속 구성된 것에 비해 약해지고, 이에 따라 화이트 밸런스의 조정도 용이해지게 된다.On the other hand, in this configuration, two B dots are positioned in each pixel, but since they are not continuous but other dots G are interposed and separated, the emission intensity is weaker than that of the continuous configuration, and thus white balance can be easily adjusted. Will be lost.

그러므로 본 고안은 칼라 PDP의 구현에 큰 효과가 있다.Therefore, the present invention has a great effect on the implementation of color PDP.
