Abstract
Description
により、2つの経路により信号を伝達する作用をもたらす。
1.第1の実施の形態(導電性を有さない間隔形成部材を使用する場合の例)
2.第2の実施の形態(導電性を有する間隔形成部材を使用する場合の例)
3.変形例
[表示装置の構成]
図1は、本技術の第1の実施の形態における表示装置の構成例を示す図である。同図における表示装置100は、駆動回路部110と、信号ケーブル119と、表示部200とを備える。駆動回路部110は、表示部200を駆動するものである。この駆動回路部110は、外部の制御装置等から入力された画像データ信号に基づいて、表示部200を駆動するための信号を生成して出力する。信号ケーブル119は、駆動回路部110と表示部200とを接続し、電気信号を伝達するものである。この信号ケーブル119は、例えば、フレキシブル配線板により構成された信号ケーブルを使用することができる。表示部200は、駆動回路部110から出力された信号に基づき、表示を行うものである。
図2は、本技術の第1の実施の形態における表示部の構成例を示す図である。同図における表示部200は、複数の表示パネル210と、複数の間隔形成部材220と、支持基板240とを備える。表示パネル210は、表示を行う最小単位のパネルである。この表示パネル210が2次元格子状配置されて、タイリング型の表示装置を構成している。間隔形成部材220は、2次元に配置された表示パネル210の間の間隔を形成するものである。この間隔形成部材220は、例えば、球形の樹脂を使用することができる。支持基板240は、表示パネル210および間隔形成部材220を支持するものである。この支持基板は、例えば、アルミニウムなどの金属により作成された基板を使用することができる。なお、表示パネル210は、特許請求の範囲に記載の表示部材の一例である。間隔形成部材220は、特許請求の範囲に記載の間隔形成部材の一例である。支持基板240は、特許請求の範囲に記載の支持部材の一例である。
図5は、本技術の第1の実施の形態における表示パネルの構成例を示す上面図である。同図における表示パネル210は、複数の画素211と、パネル基板212とを備える。画素211は、発光素子を備え、表示のための光を放射するものである。この画素211は、パネル基板212上に、2次元に配置される。発光素子としては、例えば、LEDを使用することができる。画素211には、発光素子に電気信号を伝達するための電気配線が配置され、この電気配線は端子部(不図示)に接続されている。
前述した間隔形成部材220は導電性を有しておらず、パネル基板間の電気信号は信号ケーブルを使用して伝達する必要があった。これに対し、本技術の第2の実施の形態では、導電性を有する間隔形成部材を使用する。
図6は、本技術の第2の実施の形態における表示装置の構成例を示す図である。同図における、表示装置101は、駆動回路部111と、表示部201と、信号ケーブル118および249とを備える。同図における表示装置101は、2つの信号ケーブルを使用する点で、図1において説明した表示装置100と異なっている。
図7は、本技術の第2の実施の形態における表示部の構成例を示す図である。同図における表示部201は、複数の表示パネル260と、複数の間隔形成部材225と、支持基板240とを備える。同図における表示部201は、表示パネル260および間隔形成部材225を使用する点で図2において説明した表示部200と異なっている。
図8は、本技術の第2の実施の形態におけるパネル基板および間隔形成部材の構成を示す図である。同図におけるaは、表示パネル260に使用するパネル基板223の構成例を示す斜視図である。同図におけるbは、表示パネル260に使用する間隔形成部材225の構成を示す断面図である。パネル基板223は、表示面228と、側面229と、間隔形成部材225と接する切欠き224を備えている。この切欠き224は、パネル基板223の上面から見た形状が円弧形状である。また、切欠きの表面には導電性の被膜、例えば、金や銅などの金属により構成された被膜を有している。間隔形成部材225は、球形状の粒子226の表面に導電性の被膜227を有する構成となっている。粒子226は、間隔形成部材220と同様に球形のスペーサを使用することができる。導電性の被膜227は、例えば、金などの金属により構成された被膜を使用することができる。
図9は、本技術の第2の実施の形態における表示パネルの構成例を示す図である。同図における表示パネル260は、切欠き224を備える点において、図5において説明した表示パネル210と異なる。図9において、画素211は、1mmピッチで配置されている。なお、図9に表したように、切欠き224は、画素211の間に配置すると好適である。比較的大きな切欠き224であっても配置可能となるからである。また、図9に表したように、隣接するパネル基板223の間をまたぐ位置にある画素211のピッチも、他の画素211のピッチと同じ1mmにすると好適である。パネル基板223の間の間隔が目地として視認されないためである。
[表示モジュールを構成する例]
前述した表示装置は、複数の表示パネルを配置することによりタイリング型の表示装置を構成していた。これに対し、本技術の実施の形態の変形例では、さらに大型の表示モジュールを構成する例である。
前述した表示パネルは、球形の間隔形成部材を使用していた。これに対し本技術の実施の形態の変形例では、面を有する間隔形成部材を使用する。
本技術の第2の実施の形態においては、画像信号のみを間隔形成部材を経由して伝達していた。これに対し、本技術の実施の形態の変形例では、全ての電気信号を間隔形成部材を経由して伝達する。
図15は、表示装置の製造手順を示す図である。まず、支持基板240に、接着剤230を塗布する塗布工程を実施する(ステップS901)。次に、1枚目の表示パネル210を支持基板240上の所定の位置に配置する第1の表示パネル配置工程と表示パネル210を支持基板240に固定する仮固定工程を実施する(ステップS902)。この仮固定については後述する。次に、変数Nに初期値2を設定する(ステップS903)。なお、Nは支持基板240上に配置した表示パネル210の枚数から1を引いた値である。次に、間隔形成部材220を配置する間隔形成部材配置工程を実施する。また、N枚目の表示パネル210の位置決めを行い配置する第2の表示パネル配置工程も実施する(ステップS904)。次に、このN枚目の表示パネル210を固定する仮固定工程を実施する(ステップS905)。次に、Nをインクリメントする(ステップS906)。
切欠き224の製造方法としては、パネル基板212の側面に研磨等の方法により切欠きを製造する方法と、パネル基板の元となる基板に穴を形成し、当該穴を通る線に沿って切断する方法とが考えられる。これらのうち、後者の方法について図面を参照して説明する。なお、以降の説明においては、切欠き224は、表示パネル260の上面から見た形状が円弧形状であり、かつ、導電性の被膜を有するものとする。また、パネル基板223はガラス含有エポキシ樹脂により構成された基板を想定する。
