摘要：

In order to improve light extraction efficiency from organic light emitting diodes (OLED), we report a novel structure of top-emission OLED by integrating a scattering reflector with micro-bumps into the substrate. The mechanism of light extraction has been investigated by evaluating the dependency of flux on the shape of the micro-bumps. It was confirmed that the scattering effect of the micro-bumps improves the light extraction of OLED. Moreover, the scattering reflector has been applied on a 20.8-inch WXGA full color AMOLED display. This is the world's first report that actually proves a light extraction technology, integrating scattering reflector, applied on AMOLED display.
