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

A new 4T2C pixel circuit formed on a silicon substrate is proposed to realize a high‐resolution 7.8‐μm pixel pitch AMOLED microdisplay. In order to achieve high luminance uniformity, the pixel circuit compensates its Vth variation of the MOSFET for the driving transistor internally by using self‐discharging method. Also presented are 0.5‐in Quad‐VGA and 1.25‐in wide Quad‐XGA microdisplays with the proposed pixel circuit.
