Description
本発明の一実施形態では、電気デバイスは、ある光学特性に対して概ね一様な値を示し、可視光に対して概ね透過性の露出された表面を含む。複数の薄膜スタックは互いに横方向に変位する。複数の薄膜スタックの各スタックは、少なくとも1つの他の上側表面の光学特性に対する値とは異なる、その光学特性に対する値を示す上側表面を有する。
1/(IO−R)=e-αL
先に述べられたように、第1の領域102は電気部品106の一部を含む。電気部品106の一部は第1の値の光学特性(この実施形態では吸収である)を有する第1の表面110を有する。第1の値は第2の領域の第2の表面112の吸収に対する第2の値とは異なる。吸収が異なる結果として、第1および第2の領域102、104が互いに対して見分けることができるようになる。第1の領域102の第1の表面110の吸収を第2の領域104の第2の表面112の吸収と正規化するために、スペクトル正規化構造108が用いられる。スペクトル正規化構造108は、電気部品106の一部とともに配置される。スペクトル正規化構造108は電気部品106の一部の上に配置されるように示されるが、スペクトル正規化構造108は電気部品106の一部の下や、電気部品106の一部の層間(ここには図示せず)などに配置されることもできる。
