"highly efficient, monochrome OLED microdisplay with >70K Nits brightness... individual OLED units series connected increasing brightness with each additional unit without raising current density in component... either achieves extremely high brightness or, at a given brightness, significantly reduces current density that determines lifetime... 5% brightness drop improves lifetime from 900 to 1300 hours... pectral emission can be specifically adjusted, enabling use in  waveguides or holographic elements"
