中文摘要	by means of refractive index gradually changed coupling layers, a highly efficient green top-emitting oled (toled) with enhanced light coupling efficiency and stable colors over angles has been realized. the refractive index transition of the coupling layers including the doping layer smoothes light extraction from the semitransparent cathode metal to the air, which is the reason for the enhancement of light coupling efficiency. the doping layer in the coupling layers also acts as a microparticle diffuser to eliminate the shift in el spectra with viewing angles. a universal simulation has also been carried out, and the result suggests that the light coupling efficiency will be enhanced further if the refractive index transition of the coupling layers is continuous.
