Bluetooth kit connects AR OLED microdisplays and smartphones
Because a display alone does not make an AR app, the scientists of the Department IC and System Design at the Fraunhofer FEP have now developed the electronics and the display to bring them simply and fast into real applications. The Bluetooth kit developed by the researchers enables direct and wireless communication with the display out-of-the-box from various input devices such as smartphones, laptops, and wristbands. They anticipate that in the near future, anyone could have a suitable microdisplay for their desired application that could be easily programmed by themselves.
In principle, the connection to narrow-band low-power radio data networks such as the Narrow-Band Internet of Things (NB-IoT) and LoRaWAN (long-range wide-area network) are also conceivable.
Besides the display, the development kits contain everything required, from the optics up to the graphical user interface (GUI) for Windows or Android devices. The kits are tools for product developers as well as app developers to test their ideas in a simple and easier way and to play with the technology. These developers can also target the market for data glasses, which is predicted to grow by over 200 % between now and 2020.
The OLED technology of the display provides sharp images with extremely high contrast and brightness, ranging from 20 to 5,000 nits (monochrome green). Interested developers can now choose from three different display variants: displays with 304×128 pixels with 12 µm² pixel size and 4-bit grayscale, 304×256 pixels with 12 µm² pixel size and 4-bit grayscale, and 720×256 pixels with 5 µm² pixel size and 1-bit black-and-white image.
