제2도는 본 고안의 평면도로서 전면유리를 생략한 것임.2 is a plan view of the subject innovation omitting the windshield.

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

100 : 본체 110 : 전면유리100: main body 110: windshield

111 : 애노드전극 120 : 배면유리111 anode electrode 120 back glass

121 : 캐소드전극 130 : 방전셀121: cathode electrode 130: discharge cell

본 고안은 칼라플라즈마 디스플레이 판넬에 관한 것으로, 특히 각 방전셀에 도포된 형광체들로부터의 광휘도가 균등하게 되도록 한 칼라플라즈마 디스플레이 판넬에 관한 것이다.The present invention relates to a color plasma display panel, and more particularly, to a color plasma display panel in which the luminance of light emitted from phosphors applied to each discharge cell is equalized.

일반적으로 칼라플라즈마 디스플레이 판넬은, 횡방향으로 다수의 애노드 전극을 갖는 전면유리와, 종방향으로 다수의 캐소드전극을 갖는 배면유리와, 상기 캐소드전극과 애노드전극이 교차되는 지점마다 R(빨강색), G(녹색), B(파랑색)의 형광체가 번갈아 도포되어 있고, 방전영역이 한정된 방전셀로 구성되어 있다.In general, a color plasma display panel includes a front glass having a plurality of anode electrodes in a transverse direction, a back glass having a plurality of cathode electrodes in a longitudinal direction, and R (red) at each intersection point of the cathode electrode and the anode electrode. , G (green) and B (blue) phosphors are applied alternately, and the discharge region is composed of a discharge cell having a limited discharge area.

그런데, 종래의 방전셀들은 그 면적이 서로 동일하기 때문에 그들에 도포된 형광체의 도포면적 또한 서로 같게 되어 있었다. 이와같은 상태에서 각 셀마다 서로 방전이 일어나게 되면 그들에 도포된 형광체들이 발광을 하게 되는데 이때, 형광체 마다에는 그 휘도가 서로 상이함에도 불구하고 방전량이 동일하여, 휘도가 높은 것을 더 밝게 발광을 함에 따라 색조합이 불균일 하게 되는 문제점이 있었다.However, since the discharge cells of the related art have the same area, the application areas of the phosphors applied thereto are also the same. In this state, when each cell discharges from each other, the phosphors applied to them emit light. In this case, the phosphors have the same discharge amount even though their luminances are different from each other. There was a problem that the sum of the tones became uneven.

본 고안의 목적은 상기의 점을 감안하여 안출한 것으로서, 형광체의 도포 면적을 서로 상이하게 하되 휘도가 높은 것은 도포를 적게하고 휘도가 낮은 것은 도포를 많이 하여 그들의 광휘도가 균등하게 되도록 함에 따라, 색조합이 원활이 이루어지도록한 칼라플라즈마 디스플레이 판넬을 제공함에 있다.The object of the present invention was devised in view of the above points, and the application areas of the phosphors are different from each other, but the higher luminance decreases the application and the lower luminance increases the application, so that their brightness is equal. The present invention provides a color plasma display panel for smooth color matching.

상기의 목적을 달성하기 위한 본 고안은, 형광체들의 휘도비례에 따라 방전셀등의 방전면적을 서로 상이하게 구성한 다음 그 방전셀마다 해당형광체를 도포하여 주는 특징이 있다.The present invention for achieving the above object is characterized in that the discharge area of the discharge cells and the like are configured differently according to the luminance proportion of the phosphors and then the corresponding phosphors are applied to each discharge cell.

이하, 본 고안의 바람직한 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

칼라플라즈마 디스플레이 판넬본체(100)가 제1도에서와 같이, 저면에 횡방향으로 복수개의 애노드전극(111)을 갖는 전면유리(110)와, 상면에 종방향으로 복수개의 캐소드전극(121)을 갖는 배면유리(120)와, 상기 캐소드전극과 애노드전극이 교차되는 지점마다 R, G, B의 형광체가 번갈아 도포되고 방전공간을 형성하는 방전셀(130)과로 구성된 상태에서, 본 고안은 제2도에서와 같이, 상기 방전셀(130)들의 해당형광체 도포면적을 각 형광체로부터의 광휘도가 균등하게 되도록 상이하게 하기 위하여, 각 방전셀의 면적을 달리하여 준 것이다. 예컨대, 형광체 R, G, B의 휘도비가 30 : 50 : 20 일때 그 해당 형광체가 도포되는 방전셀들의 면적비를 30 : 20 : 50으로 하여준다. 첨부도면에서 A는 R형광체 도포면적을, B는 G형광체 도포면적을, C는 B형광체 도포면적을 각각 나타낸 것이다.As shown in FIG. 1, the color plasma display panel body 100 includes a windshield 110 having a plurality of anode electrodes 111 on the bottom thereof in the transverse direction, and a plurality of cathode electrodes 121 in the longitudinal direction on the top surface thereof. In the state consisting of a back glass 120 having, and a discharge cell 130, the phosphors of R, G, B are alternately applied at each point where the cathode electrode and the anode electrode intersect, forming a discharge space, the present invention is a second As shown in the figure, the area of each discharge cell is varied so that the corresponding phosphor coated areas of the discharge cells 130 are different so that the luminance of light from each phosphor is equalized. For example, when the luminance ratio of the phosphors R, G, and B is 30:50:20, the area ratio of the discharge cells to which the phosphor is applied is set to 30:20:50. In the accompanying drawings, A denotes an R phosphor coated area, B denotes a G phosphor coated area, and C denotes a B phosphor coated area, respectively.

상기와 같이 구성하여 주면, 형광체들의 휘도비에 따라 휘도가 큰 G형광체는 방전셀의 크기가 B처럼 작게 되어 그 도포면적이 줄어들고, 그 휘도비가 작은 B형광체는 방전셀의 크기가 C처럼 크게 되어 그 도포면적이 커지고, 휘도비가 중간인 R형광체는 방전셀의 크기가 A처럼 중간정도로 되어 그 도포면적이 중간정도의 크기로 되는 것이다.According to the above configuration, the G-phosphor having a high luminance according to the luminance ratio of the phosphors has a discharge cell size as small as B, so that the coating area thereof is reduced, and the B phosphor having a low luminance ratio has a large discharge cell size as C. The R phosphor having a large coating area and a medium luminance ratio has a medium discharge cell size of A, and the coating area has a medium size.

따라서, 방전이 일어날때 그 각각의 방전량이 서로 상이하게 되어 각 방전셀들에 도포된 형광체들의 광휘도가 서로 균등하게 되는데, 이는 휘도가 큰 형광체는 적은 방전으로 광휘도가 약해지고 또한, 휘도가 작은 형광체는 많은 방전으로 광휘도가 커지고 또한, 휘도가 중간인 형광체는 중간정도의 방전으로 그 광휘도가 중간정도로됨에 따라, 결과적으로 서로 균등한 광휘도를 얻을 수가 있는 것이다.Therefore, when the discharge occurs, the respective discharge amounts are different from each other, so that the luminance of the phosphors applied to the respective discharge cells is equal to each other. The phosphor has a large brightness with a large number of discharges, and a phosphor having a medium brightness has a medium brightness with a medium discharge, resulting in equal brightness.

이상에서와 같이, 본 고안에 따르면 균등한 광휘도로 인하여 이들의 색조합이 향상되고 그에 따라 보다 선명한 화질을 얻을 수가 있는 등의 장점을 제공해주는 유용한 고안인 것이다.As described above, according to the present invention, it is a useful design that provides advantages such that the sum of their tones is improved due to the uniform brightness and thus, a clearer picture quality can be obtained.
