Description
図1は、本実施形態に係る表示システムの模式図である。図1に示すように、本実施形態に係る表示システム1は、表示装置2と、基部4とを備える。基部4は、壁や柱などの構造物である。表示装置2は、基部4に取付けられて、画像を表示する。より詳しくは、表示装置2は、基部4の表面に形成される窪みである凹部4Bに埋め込まれる。なお、本実施形態における基部4は、壁や柱などの構造物であるが、任意の物体であってよく、例えば手帳のカバーなどの小型の物体であってもよい。表示装置2も、例えば対角線の長さが85インチ程度の大型の表示装置であるが、サイズはこれに限られず任意であり、小型のものであってもよい。
図2は、本実施形態に係る表示装置の模式的な平面図であり、図3は、本実施形態に係る表示装置の模式的な一部断面図である。図2及び図3に示すように、表示装置2は、アレイ基板9と、複数の無機発光体100と、表面層5とを備える。アレイ基板9は、表示装置2の各画素Pixを駆動するための駆動回路基板であり、バックプレーン又はアクティブマトリクス基板とも呼ばれる。詳しくは後述するが、アレイ基板9は、複数のトランジスタ、複数の容量及び各種配線等を有する。図2及び図3に示すように、無機発光体100は、アレイ基板9の方向Dz1側に設けられて、マトリクス状に並んでいる。すなわち、無機発光体100は、アレイ基板9の方向Dz1側において、第1方向Dx及び第2方向Dyに並んでいる。無機発光体100は、無機発光ダイオード(LED:Light Emitting Diode)であり、方向Dz1側に光Lを照射する。なお、無機発光体100は、広がり角をもって光Lを照射するため、方向Dz1に沿ってのみ光Lを照射するわけではない。無機発光体100は、平面視で、数μm以上、300μm以下程度の大きさを有する無機発光ダイオードチップであり、一般的には、一つのチップサイズが100μm以上をミニLED(miniLED)、100μm未満~数μmのサイズをマイクロLED(micro LED)と呼ばれる。本発明ではいずれのサイズのLEDも用いることができ、表示装置の画面サイズ(一画素の大きさ)に応じて使い分ければよい。各画素にマイクロLED(micro LED)を備える表示装置は、マイクロLED表示装置とも呼ばれる。なお、マイクロLEDのマイクロは、無機発光体100の大きさを限定するものではない。
次に、表示システム1の組み立て方法について説明する。図12は、本実施形態に係る表示システムの組み立て方法を説明する図である。図12のステップS10に示すように、表示システム1を組み立てる際には、基部4に表示装置2を取り付ける。具体的には、基部4の凹部4B内に、表示装置2を収納する。ステップS10においては、表示装置2には表面層5が取り付けられておらず、基部4にも、表面4Aを構成する基部表面層4Sが取り付けられてない。
次に、表示システム1を視認した場合の見え方について説明する。図13は、無機発光体を消灯している場合の表示システムの外観を示した模式図であり、図14は、無機発光体を点灯している場合の表示システムの外観を示した模式図である。図13に示すように、表示装置2の無機発光体100を消灯している際、より詳しくは表示装置2の全ての無機発光体100を消灯している際には、無機発光体100は、光Lを発光しない。従って、無機発光体100を消灯している際に表示システム1を平面視した場合、表示システム1は、表示装置2の表面層5の表面5Aが視認され、表示装置2の表面5Aと基部4の表面4Aとの外観が、表面1Aとして、連続するように視認される。さらに言えば、表面層5の透過部8は十分に小さく視認され難いため、無機発光体100を消灯している際には、表示システム1は、表示装置2の遮断部6の表面6Aの外観と、基部4の表面4Aの外観とが、連続するように視認される。このように、無機発光体100を消灯している際には、表面5Aと表面4Aとの間の境界が視認されず、表面4Aと表面5Aとの区別がつかず、表面4Aと表面5Aとが同一の1つの表面1Aとして視認される。このように、表示システム1は、表示装置2を消灯中には、表示装置2の表面5Aと基部4の表面4Aとの区別がつきにくくなり、表示装置2が基部4であると視認されて、表示装置2が目立たなくなる。なお、例えば表示装置2に近づくと、透過部8を介して、無機発光体100やその周囲の配線が視認される可能性があるが、無機発光体100やその周囲の配線からの可視光の反射は、偏光板94によって抑えることができ、視認され難くできる。
次に、上述の実施形態の変形例について説明する。図15は、第1変形例に係る表示システムの模式図である。図15の第1変形例に示すように、表示システム1は、表示装置2の表面層5の表面5Aに光LIを照射する照明部96を備えていてよい。この場合、照明部96は、図示しない照明制御部に、可視光の光LIの照射が制御される。図15の(a)に示すように、照明部96は、表示装置2の無機発光体100が消灯する場合、すなわち表示装置2が画像PIを表示しない場合に、表面層5の表面5Aに光LIを照射する。なお、照明部96は、表面層5の表面5Aと、表面5Aの周辺の基部4の表面4Aとに、光LIを照射してよい。一方、図15の(b)に示すように、照明部96は、表示装置2の無機発光体100が点灯する場合、すなわち表示装置2が画像PIを表示する場合に、照明部96は、光LIの照射を停止する。このように、照明部96は、無機発光体100の消灯時に表面5Aに光を照射し、無機発光体100の点灯時に表面5Aへの光の照射を停止する。これにより、画像PIを表示しない際には基部4を明るくしつつ、画像PIを表示する際には、表面4A、5Aへの光の照射を停止するため、表面4A、5Aからの可視光の反射が抑えられ、画像PIのコントラスト低減を抑制できる。
