QD‐OLED device performance is unsatisfactory nowadays, due to the limited efficiency of blue OLED material as well as the low efficient converting rate of QD material. Here we proposed a novel structure of QD‐OLED, using white OLED as the excitation. The device shows higher optical efficiency compared with QD‐OLED with Blue OLED as excitation. In addition, a 6.6 inch green QD‐OLED was demostrated with the proposed structure.
