We developed an AM‐OLED display having saturated RGB, high efficiency and good contrast ratio. These properties, which outperform those of a conventional White OLED and color filter (WOLED+CF) system, were achieved with a unique combination of white emitter, microcavity structure and color filter array (WOLED+MC+CF).

A 0.23 inch nHD+ OLED microdisplay has been developed with high-resolution 7.8μm pixel pitch, long life, and lower power consumption than prior OLED microdisplays. This newly developed OLED microdisplay is suitable for wearable displays and viewfinders. A 0.39 inch XGA and 0.7 inch Full-HD microdisplay will also be discussed.

We have developed a high-definition (0.5-inch
