Description
ηcp,ext〜1/2n2 org(1)
によって近似することができる。
ここで、ηcp,extは外部結合効率であり、norgはITO/有機層の合計である。基板の中に捕らえられた光の割合ηcp,subsおよびITO/有機層の中に捕らえられた光の割合ηcp,orgはそれぞれ、
ηcp,subs=cosθorg,c1−cosθorg,c2(2)
ηcp,org=cosθorg,c2(3)
によって与えられる。ここで、θorg,c1およびθorg,c2は、それぞれ有機層−空気間および有機層−基板間の臨界角である。アプリケーション、一般に照明およびフラットパネルディスプレイの目的には、ディスプレイデバイス、例えば図3で参照されたディスプレイデバイス300からの全放射光のわずか20パーセントである、基板表面から放射される光(ηcp,ext)が最も有用である。
