The efficiency of conventional bottom-emission OLED can be largely enhanced by using a high-refractive-index patterned substrate, because the waveguide mode in the organic layer can be out-coupled into the high-n substrate. Then the light can be further out-coupled by pre-patterned microlens without attaching a conventional plastic microlens-array film. In our previous test of white OLED, the enhancement ratio of PE (lm/W) can reach 110%, similar to the result in Panasonic paper.
