WebWe show that lowering the reflectance of OLEDs, which is required for increasing the contrast, can also lead to a reduction of their efficiency when a small microcavity effect is not maintained in their structure. WebIn the typical structure of a turboshaft aero-engine, the mass flow of the cooling air in the rotor-stator cavity is controlled by the inlet seal labyrinth. This study focused on the swirl …
Micro Cavity Effect in GaN-Based Light-Emitting …
WebDec 1, 2013 · The device efficiency and angular color stability of white top‐emitting OLEDs 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 … WebJul 27, 2011 · The study on micro-cavity in organic light-emitting diode (OLED) demands understanding the theory of multi-layer films. It is because OLED is basically an optical … magician是什么意思
