Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201300392-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The device efficiency and angular color stability of white top‐emitting OLEDs</bold> is significantly improved by a decrease in thickness of the semitransparent silver cathode. The transmittance increases and the micro‐cavity effects are reduced. Inserting a 2 nm gold wetting layer, the silver layer can be reduced to 5 nm achieving higher efficiency and comparable color stability to the bottom‐emitting reference. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3zmjm4gr" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
