A look into eMagin's AR/VR dPd technology

In 2012, we first heard that eMagin is developing direct emission (or direct patterning, as the company calls it) OLED microdisplays. Fast forward into 2020, and the company is aiming to soon start producing such displays (it already launched its first such panel, see more below). In this article we'll look into the technology and the latest updates from eMagin.

White OLED with CF structure vs dPd structure (eMagin)
All current OLED microdisplays on the market from all producers use a white OLED with color filter. This is a simple design, but it is wasteful in energy, as the filters block around 80% of the light, and in addition to achieve the white color one needs to use a blue OLED emitter (in addition to a yellow one, or red and green ones) - and blue is the least efficient color for OLED emission.
