我们发展了一种通过在顶部发射的白色有机电致发光器件(OLED)上沉积外部可调光学薄膜来实现蓝光、绿色和红光发射的方法。通过控制覆盖在发射层上的多层光学膜的波长依赖性透射率,实现了用于全色显示的三原色,包括蓝色、绿色和红色发射。这种器件构造的优点在于,OLED的发射颜色可以经由外部光学膜来调节,这不影响器件的电特性。这可以提供一种通过使用白色顶部发射OLED来实现全色显示的方法。
We developed an approach to realize blue, green and red emission from top-emitting white organic light-emitting diodes (OLEDs) through depositing exterior tunable optical films on top of the OLEDs. Three primary colors for full color display including blue, green and red emission are achieved by controlling the wavelength-dependent transmittance of the multilayer optical films overlaid on the emissive layer. The advantage of such a device configuration is that the emissive color of the OLEDs can be tuned via the exterior optical films which do not affect the electrical characteristics of the device. This may provide a way to realize full color display by using white top-emitting OLEDs.
