Abstract

We demonstrate a hybrid device with high ambien t-contrast-ratio (>133.8:1) under any ambient co nditions by vertically integrating a reflective LCD and a transparent OLED. The twisted nematic LC cell is placed beneath the OLED to improve dev ice transmittance by 53.8% due to the asymmet ric emission from both-sides of the transparent OLED.
