The Fraunhofer FEP institute has teamed up with Korean-based LetinAR to develop an ultra-low-power OLED microdisplay based optic lens for AR applications. The Fraunhofer and LetinAR will present the new technology at MWC 2019.
LetinAR's PinMR technology uses the Pinhole Effect with tiny mirrors and embedded them with eyeglass lenses. The PinMR mirrors reflect the light generated by a microdisplay and guide it into the user's pupils. Users may view the virtual image created via microdisplay equipped with magnifying see-through optics as well as the image from the real world at ease. Human eyes cannot detect the mirrors, which are smaller than pupils. Only the virtual image formed by the light reflected by those mirrors is visible.
The Fraunhofer FEP says that the extremely small size of its ultra-low power OLED microdisplay is perfectly suited for small, miniaturized and lightweight systems that are wearable and simple to integrate into glasses, caps, or helmets. The currently uses microdisplays are monochrome green, but a full-color version can be developed.
