eMagin, the OLED microdisplay maker, demonstrated a full-color directly-patterned OLED microdisplay, the first time that such a display prototype has been developed. eMagin's display (called the OLED-ULT) features a high luminance of 4,500 nits and a PPI of 2,645.
eMagin targets VR and AR applications for this high-brightness and high-resolution display, and the company says that the demonstrated generated "tremendous interest", including from some Tier-1 display company representatives.
The company says that it shipped early engineering samples to a few key customers, and it aims to be able to ship some more samples to other customers in Q4 2016. In March 2016, eMagin estimated that it will be in manufacturing readiness in 2017.
