Field of the Invention The present invention relates to a plasma display panel (PDP) using light emission due to discharge for display, and in particular, to obtain an image with high color purity by intercepting color interference between neighboring pixels. A plasma display panel (PDP) relates to a color purity improving structure.

일반적으로 플라즈마 디스플레이 패널(PDP : Plasma Display Panel)은 방전에 수반되는 발광현상을 이용하여 글자 및 화상을 디스플레이하는 박형(薄型) 표시장치로써, 이러한 플라즈마 디스플레이 패널(PDP )은 2개의 유리기판에 일정한 방전 개시전압을 얻기 위해 규칙적으로 배열한 한 쌍의 전극을 설치하고, 그 사이에 Ne을 주체로 한 가스를 봉입한 구조로, 이를 좀더 구체적으로 살펴보면 다음과 같다.In general, a plasma display panel (PDP) is a thin display device that displays letters and images by using a light emission phenomenon accompanying discharge, and such a plasma display panel (PDP) is fixed to two glass substrates. In order to obtain a discharge start voltage, a pair of electrodes arranged regularly, and a structure in which a gas mainly containing Ne is enclosed therebetween, will be described in more detail as follows.

It is composed of a combination of the lower glass substrate 2 is attached to the phosphor 8 partitioned for each color, the dielectric layer (such that the phosphor 8 partitioned by R, G, B can emit light according to a signal) 3) a display electrode 5 and a bus electrode 6 are provided, and the phosphor 8 is provided with an address electrode 9.

이와 같이 구성된 상기 플라즈마 디스플레이 패널(PDP)은 상기 표시전극(5), 버스전극(6) 그리고 주소전극(9)에서 발생되는 펄스신호의 조합으로 인가된 신호에 따른 방전으로 R, G, B가 발광되므로써 이와 같이 발광된 R, G, B의 색합성으로 하나의 화소(pixel)가 형성되고, 이러한 화서(pixel)의 조합으로 원하는 화상을 얻을 수 있게 된다.The plasma display panel PDP configured as described above has R, G, and B as discharges according to a signal applied by a combination of pulse signals generated from the display electrode 5, the bus electrode 6, and the address electrode 9. By emitting light, one pixel is formed by the color combinations of R, G, and B emitted in this way, and a desired image can be obtained by the combination of these inscriptions.

그런데, 이러한 플라즈마 디스플레이 패널(PDP)은 충진된 가스의 방전시 발광되는 R, G, B가 상부유리기판에서 균일하게 확산되지 못하게 될 뿐만 아니라 이웃된 화소(pixel)간에 상호 색간섭이 발생하여 화상의 해상도 및 색순도를 떨어뜨리게 되는 문제점이 있었다.However, such a plasma display panel (PDP) not only prevents the R, G, and B light emitted from discharging the filled gas uniformly from the upper glass substrate, but also causes mutual color interference between adjacent pixels. There was a problem that drops the resolution and color purity of.

이에 본 발명은 상술한 바와 같이 종래의 제반 결함을 감안하여 이루어진 것으로, 그 목적은 R, G, B가 상부유리기판 내에서 균일하게 확산되게 하고, 또한, 이웃된 화소(pixel)간에 색간섭을 상호 차단하여 해상도 및 색순도가 향상된 화상을 얻을 수 있도록 하는 플라즈마 디스플레이 패널(PDP)의 색순도 개선구조를 제공함에 있다.Accordingly, the present invention has been made in view of the conventional defects as described above, and its object is to allow R, G, and B to be uniformly diffused in the upper glass substrate, and to provide color interference between neighboring pixels. An object of the present invention is to provide a color purity improving structure of a plasma display panel (PDP), which is capable of blocking an image to obtain an image having improved resolution and color purity.

이러한 플라즈마 디스플레이 패널(PDP)의 색순도 개선구조는 각 R, G, B형광체에 대응되는 상부유리기판의 내측면에 상향으로 구면이 형성되어 발광된 R, G, B를 각 화소(pixel)내에서 상부유리기판에 균일하게 확산시키는 확산렌즈와, 상기 확산렌즈에 의해 각 화소(pixel)내에서 균일하게 색합성된 R, G, B를 반사하여 이웃된 화소(pixel)와의 색간섭을 차단하는 반사거울이 구비된 것을 특징으로 하는 것이다.The color purity improving structure of the plasma display panel (PDP) has a spherical surface upwardly formed on the inner surface of the upper glass substrate corresponding to each of the R, G, and B phosphors, and emits R, G, and B emitted within each pixel. Diffusion lens that diffuses uniformly on the upper glass substrate, and R, G, and B that are uniformly synthesized in each pixel by the diffusion lens, thereby preventing color interference with neighboring pixels. It is characterized in that the mirror is provided.
