Description

【0001】
【発明の属する技術分野】
画像表示装置用金属隔壁及びその製造方法並びに画像表示装置に関する。
【0002】
【従来の技術】
プラズマディスプレイパネル(以下PDPと称す)は薄型・軽量・高輝度・広視野角を特長とした次世代表示デバイスの本命として登場、急速にその市場を拡大している。PDPは、薄型にするため、対向する前面ガラス板と背面板の周囲をシールガラスで封じて放電ガスを収容する気密容器を構成するものが多く採用される。前、背面板間には隔壁が形成され、この隔壁と前、背面板で周囲を囲まれた空間が一つの表示セルとなる。表示セル内面には蛍光体が被着されて、放電によって発生する紫外線で、蛍光体は各色の可視光を発する。
複数の放電セルを配置した画像表示装置においては、隣接セルへのクロストークを防止するため、絶縁性の隔壁が必要とされておりPDPでは、ガラスペーストの多層印刷や、サンドブラスト加工によりガラスの隔壁が利用されている。しかしながら、この製法では製造コストが高くなり、応用範囲が限定され、特にPDPは民生用として普及していない一因である。
【0003】
そこで、特許文献1では、製造コスト低減の目的から、微細な表示セルがエッチングされた金属基板に無機誘電体を被覆して金属隔膜を形成し、該金属隔壁をPDPに応用する技術が開示されている。
特許文献2では、複数の貫通孔を有した金属薄板に絶縁層を形成した後、当該金属薄板を数枚積層し、450〜700℃の温度範囲で接合させて金属隔壁とする製造方法、複数の貫通孔を有した金属薄板を積層した後、該複数積層された金属薄板に絶縁層を形成して金属隔壁とする製造方法が開示されている。
さらに、特許文献3には格子に組んだPDP用メタル隔壁の技術が開示されている。

【発明が解決しようとする課題】
特許文献3に開示されている格子型は、周壁と隔壁とのみが、切り裂き溝で相互に嵌めあわせているもので、製造工程で隔壁が動き、セル寸法の安定性等が無く、また画像表示装置に組まれた後もセル寸法の安定性がない。
また、同発明では、格子には前面ガラスパネルと背面ガラスパネルが装備されるが、その際に必要な平坦性が確保されていない。
本発明の目的は、セル高さが高く、セル寸法が安定した,平坦性にすぐれたPDP用格子状メタル隔壁を提供することである。
【0006】
【課題を解決するための手段】
本発明者等は、上記した従来技術の課題を解決するために、圧延加工された金属板の特性と溶接性に配慮し、鋭意検討をした結果、本発明に到達したものである。
【0007】
つまり
(1)圧延加工された金属板であって、その圧延方向に対する幅方向を前面ガラスパネルと直交するように配置し、かつ直交する隔壁同士の交点は相互に予め形成した溝で相互に埋め合わせられ、かつその交点の全てもしくは選択された交点において、直交する隔壁同士が一部で溶着していることを特徴とするPDP用格子状メタル隔壁、
(2)直交した格子状に組み立てられた面同士の前面ガラスパネル側の交点、背面ガラスパネル側の交点のいずれか一方、或いは両方の全ての交点もしくは選択された交点において溶着していることを特徴とする上記(1)記載のPDP用格子状メタル隔壁、
(3)溶着部分を含む交点が、相隣り合わないで配列することを特徴とする上記(1)又は(2)記載のPDP用格子状メタル隔壁、
(4)溶着部分が前面ガラスパネルに接する上記金属板面又は背面ガラスパネルに接する上記金属板面において、ガラスパネルと接する面より内側(前面と背面の間)で形成され、内側(前面と背面の間)で形成され、かつ溶接金属も同内側に配置したことを特徴とする上記(1)〜(3)記載のPDP用格子状メタル隔壁、

である。
【0008】
【発明の実施の形態】
以下に本発明の限定理由を述べる。
(1)圧延幅方向を全面ガラスパネルと直交させることで、強度、熱伸縮等の材料特性の安定化を図ることができる。格子点での嵌合と溶接により、格子の形状安定性を向上させる。溶着が嵌合面全面に及ぶと溶接の際の熱入力が多くなり、熱変形によるセルの歪が大きくなる。
(2)圧延加工された金属板をその圧延方向に直角な幅方向が前面ガラスパネルと直交するように配置することにより、隔壁の高さを調整することができる。特にエッチングを用いて隔壁を作る製造方法と比較して高い隔壁が作れることが特徴である。
【0009】
(3)溶着格子点を隣り合わせないことにより、残留応力、格子変形の原因となる溶接の熱の分散を図ることができる。
(4)溶接ビード(溶接金属)が、リブの切断面を含む面から突起すると、パネルと組み立てる際に、パネルに局部的な応力をかけることになり、ガラスの破損パネル及び隔壁の変形の原因となる。
(5)格子形状を安定させるために溶接時に張力を張る。ただし、張力が強すぎると溶接の発熱時に金属材料の耐力が下がった部分で、歪等が不必要に入り格子形状の悪化の原因となる。
(6)レーザー光が大気圧でのハンドリング性の良い条件で、エネルギー密度が高い局部溶接が可能である。また、スリット状金属箔で形成され格子点密度が高いため、溶接部の位置を制御する上でレーザー光が優れている。
【0010】
(6)格子を組む際、嵌合を容易にするため、開口部を広くしておくのが良い。ただし、嵌合の安定位置では溝と金属板の厚みとのギャップが大きいと最終的な格子の寸法精度が安定しない。
(7)前面ガラスパネルに掛かる大気圧に対する隔壁の強度を高めるためと、ピクセル間の隔壁の厚みは輝度に影響が少ないことから、適度にピクセル内RGB各セル間の隔壁よりも厚くする。つまり、ピクセル間の隔壁の厚みを、ピクセル内RGB各セル間隔壁の厚みの1.3倍以上とする。
(8)中間壁の前面は蛍光体が塗布され輝度に大きく影響するため、厚肉化することが好ましく、中間隔壁の金属板の厚みをセル間隔壁金属板の厚みの1.5倍以上とする。
(9)上述の隔壁を用いた画像表示装置は輝度、解像度等ディスプレイ性能に優れる。
【0011】
【実施例】

さらに各材料について圧延直角方向と圧延平行方向にスリットした。

【0014】
(実施例3)
各板厚の金属板(35μm、50μm、100μm)の溝の開口部を35μmの溝については47μm、50μmの溝については66μmになるようにした。そして図3のように格子に組んだのち、図2のように溶接を行い、ガラスパネルにて格子をはさんで、溶接部分がガラスに接触しないことを確認した。

[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The reasons for limiting the present invention are described below.
(1) By making the rolling width direction perpendicular to the entire glass panel, it is possible to stabilize material properties such as strength and thermal expansion and contraction. By fitting and welding at lattice points, the shape stability of the lattice is improved. If the welding extends over the entire fitting surface, the heat input during welding increases, and the cell distortion due to thermal deformation increases.
(2) By arranging the rolled metal plate so that the width direction perpendicular to the rolling direction is orthogonal to the front glass panel, the height of the partition can be adjusted. In particular, it is characterized in that a higher partition can be formed as compared with a manufacturing method in which the partition is formed by etching.
[0009]
(3) Since the welding grid points are not adjacent to each other, it is possible to disperse welding heat that causes residual stress and grid deformation.
(4) When the weld bead (weld metal) protrudes from the surface including the cut surface of the rib, local stress is applied to the panel when assembling with the panel, which causes the glass break panel and the deformation of the partition wall. It becomes.
(5) Tension is applied during welding to stabilize the lattice shape. However, if the tension is too high, distortion or the like is unnecessary at a portion where the proof strength of the metal material is reduced at the time of heat generation of welding, which causes deterioration of the lattice shape.
(6) Local welding with a high energy density can be performed under the condition that the laser light is easy to handle at atmospheric pressure. Further, since the lattice point density is high due to the formation of the slit-shaped metal foil, the laser beam is excellent in controlling the position of the welded portion.
[0010]
(6) When assembling the lattice, it is preferable to widen the opening to facilitate the fitting. However, if the gap between the groove and the thickness of the metal plate is large at the stable fitting position, the final dimensional accuracy of the lattice is not stable.
(7) In order to increase the strength of the partition against the atmospheric pressure applied to the front glass panel, and since the thickness of the partition between pixels has little effect on the luminance, the partition is appropriately made thicker than the partition between the RGB cells in the pixel. That is, the thickness of the partition wall between pixels is set to be 1.3 times or more the thickness of the inter-pixel RGB inter-cell wall.
(8) Since the front surface of the intermediate wall is coated with a phosphor and greatly affects the luminance, it is preferable to increase the thickness of the intermediate wall. I do.
(9) An image display device using the above-described partition has excellent display performance such as luminance and resolution.
[0011]
【Example】
Here, a rolled material of an Fe-42 mass% Ni-based alloy was used to evaluate the assemblability. It is necessary to select a material having a thermal expansion coefficient similar to that of a glass panel as the material used for the metal partition, and is not limited to the alloy used in the present embodiment.
As the rolled material of the Fe-42% by mass Ni-based alloy, a metal thin plate having a thickness of 50 μm used for the pixel interval wall, 35 μm for the RBG cell interval wall in the pixel, and 100 μm for the intermediate partition shown in FIG. 3 was prepared.
Further, each material was slit in a direction perpendicular to the rolling direction and a direction parallel to the rolling direction.
[0012]
(Example 1)
Using a metal plate in the rolling direction of 50 μm to be used for the pixel spacing wall, using a metal plate and forming a grid in four rows and four rows (16 grid points), welded all 16 points and welded so as not to be adjacent to each other All of them were stable. Furthermore, those that are welded so as not to be adjacent to each other have less deformation than those that are completely welded.
[0013]
(Example 2)
A 50 μm rolling direction used for the pixel spacing wall, a metal plate is used to form a grid in four rows and four rows (16 grid points) and 0.2% proof stress is welded and welded only. As a result, it was possible to more stably produce the one welded with an added 0.2% proof stress.
[0014]
(Example 3)
The opening of the groove of the metal plate (35 μm, 50 μm, 100 μm) of each thickness was set to 47 μm for the 35 μm groove and 66 μm for the 50 μm groove. Then, after assembling into a grid as shown in FIG. 3, welding was performed as shown in FIG. 2, and the grid was sandwiched between glass panels to confirm that the welded portion did not come into contact with the glass.
[0015]
【The invention's effect】
In image display devices and PDPs, a partition having a high cell height, a stable cell size, and excellent flatness is used for the display performance, such as luminance and resolution, by using a metal plate assembled in a grid pattern. PDP can be provided.
