Description
本発明は、携帯型DVD、携帯電話、携帯型テレビ受像機、ビデオゲーム、携帯型メディアプレーヤー、又はその他の携帯型表示装置など、多数の画像技術の応用に関して有利な効果をもって実現可能なものである。
本発明の大きな目的は、従って、従来技術に係るコンパクト光学表示装置の欠点を克服し、また、具体的な要請に基づいて、性能を改良したその他の光学構成要素や光学系を提供することである。
LOEの動作の主たる物理的な原理は、光波がLOEの外面から基板の中へ内部全反射によって捕捉されることである。さらに、LOE内に捕捉された光波は、部分反射表面のアレイによって、観察者の目に向けて出力結合される。従って、良好な光学品質を有する、ゆがみのない画像を得るために、部分反射表面のみならず、基板の外面の表面品質を高くすること、また他方では、LOEの作成工程が、可能な限り簡素化されすっきりしたものであることが重要である。
特に図面の内容に即して、図示した具体的な内容は単なる一例なのであって、ただ本発明の好ましい実施形態の例示として述べることを目的とすることが強調される。発明の原理や概念の説明として最も有益で直ちに理解し得ると思われる形で提示するものである。この観点で、発明の原理的な理解に必要となる以上の詳細に関して、発明を構造的に示そうとはしていない。図面を参照して行われる説明は、当業者に対して、発明のさまざまな例がどのように実施できるかということに関して示唆となるであろう。
図面において、
