Description
現在、世界は次世代ディスプレイに注目しており、マイクロ発光ダイオード(マイクロLED)は最も有望な技術の1つである。手短に言えば、マイクロLEDは、LEDを小型化してマトリクス化し、これにより何百万個の、さらには何千万個のダイを基板上に配列する技術であり、これらのダイは100ミクロンより小さく髪の毛より薄い。現在のOLED(organic light-emitting diode:有機発光ダイオード)技術に比べると、マイクロLED表示デバイスも自発光デバイスであるが、異なる材料を利用する。従って、マイクロLED表示デバイスは、スクリーンの焼き付きの問題を解決することができ、この問題はOLED表示デバイスにおける最も致命的な問題である。それに加えて、マイクロLED表示デバイスは、低電力消費、高コントラスト、広い色域、高い明度、小型かつ薄型のサイズ、軽量かつ省エネルギーという利点をさらに有する。従って、世界中の主要製造所が先を争ってマイクロLED技術の研究開発に投資している。
高解像度(UHD(ultra-high definition:超高解像度)、AR/VR(augmented reality/virtual reality:拡張現実感/仮想現実感)のような高PPI(pixels per inch:1インチ当たりの画素数))表示デバイスの要求の下で、比較的小型のマイクロLEDの半導体層内に形成される金属グリッドの製造工程許容誤差はより小さくなり、このことは表示デバイスの製造歩留まりに直接の影響を与える。従って、高解像度の要求を満足することができ高い製造歩留まりを有するマイクロLED表示デバイスを提供することが望まれる。
本発明の1つ以上の好適例は、高解像度の要求を満足することができ、より高い製造歩留まりを有するマイクロLED表示デバイスを提供することにある。
