A high‐efficiency organic light‐emitting diode (OLED) microdisplay has been developed with some new technologies including microlens array. We focused on the improvement of the out‐coupling efficiency and achieved three times higher efficiency as compared with conventional OLED. By using our developed technologies, it is possible to improve the maximum luminance from 1600 to 5000 cd/m 2 while maintaining same lifetime.
