Description
図4は、改善された色域を有するディスプレイシステム(400)の一実施形態である。ディスプレイシステム400は、図1のディスプレイシステムと概ね同様に構成されているが、図1に加えて、ディフューザ/光シェイパ106と第1のポラライザ108との間に配置された色ノッチフィルタ402を有する。色ノッチフィルタのこの位置は、これが、最も光の視準が合う光学経路の部分であるときに望ましい。色ノッチフィルタは、この適用のために光学経路の他の部分に置いてもよいことが認識されよう。
色ノッチフィルタの追加による図1に示されるディスプレイシステムの色域の改善とは別に、異なる、おそらくはよりエネルギー効率の良い設計を有する他のディスプレイシステムに同じ改善を与えることが望ましいことがある。
