In this work, we apply screen-printed method for light extraction layer fabrication for an organic light-emission diode. Screen-printing is a large-area, solution-processed, and low cost, which is appropriate for volume production in organic lighting application. With TiO₂, the interfaces between glass substrate to the air were modified. The high refraction index of TiO₂ cause the light could be extracted smoothly at glass/TiO₂ interface. By incorporating screen-printed TiO₂ nanocomposite, the luminescence efficiency enhanced over 65%.
