Paper Abstract

We demonstrated a 42% luminance enhancement by attaching MLF (Micro Lens Film) on the bottom emitting OLED. Higher density of MLF extracted more substrate mode to air. We also investigated the compatibility of MLF and Circular Polarizer (CP) on the bottom emitting OLED. It is found that the efficiency of bottom emitting OLED with MLF and CP decreases comparing to the reference OLED device, which has CP alone. Simulation shows that large portion of light is reflected back into CP at the surface of MLF and air. Back reflected light from MLF is absorbed in CP layer. We have also shown that OLED blur image be enhanced by reducing substrate thickness.
