LetinAR – Truly-wearable Augmented Reality – Closer to Reality by Combining Highly Efficient See-through Optics and Ultra-low Power OLED Microdisplay Technologies
LetinAR is a Korean startup company, which is specialized in the development of novel optics for AR glasses. LetinAR's PinMR™ technology will set new standards for the production of these wearables. Therefore they have applied the so-called “Pinhole Effect” to tiny mirrors and embedded them with eyeglass lenses. Respective PinMR™ reflects the light generated by a microdisplay and guides it into human 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.
This specially developed Pin Mirror optic (PinMR™) has now been combined with Fraunhofer FEP's ultra-low-power OLED microdisplay technology, known for its ultra-low power consumption. The extremely small size of the 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 display's OLED technology enables sharp images with very high contrasts and brightness over very wide dynamic range (monochrome green so far, yet basically expandable to full-color). In addition, an extra, innovative Bluetooth concept now makes it possible to communicate with the wearable/display in an energy-saving manner. Data transmission from, for example, scanner data to storage locations or filling levels can be transmitted directly to the AR glasses of a picker in logistics. And this without having to interrupt the work shift for loading times of the glasses.
