Glasses with OLED and eye-controlled microdisplay will be presented at the electronica trade fair in Munich

When the world’s eyes are looking at Google for glasses and Samsung for OLED based TVs another company worked differently. Recently, Fraunhofer – an application-oriented research based organization in Europe – has presented data glasses with OLED microdisplay allowing the user to look at the same time both the real world and the virtual world for information that can be controlled with the help of eyes.

“We have a completely new generation of personal information management systems,” Project manager Dr. Rigo Herold, said in a statement. “The data glasses allow us to see the real world in the normal way, while at the same time registering our eye movements with the camera. One glance at the arrow key turns the page. Despite the fact that Google’s data glasses, for instance, might be a little more stylish in appearance, navigating through the menu still requires using joysticks, whereas our glasses do not.”

We think that students would dream about the use of such glasses in exams more than any other person. However, these glasses would be helpful for a wide range of professionals such as doctors or surgeons while checking the patients and technicians while working on cars or such objects as they can read the manual at the same time.

These eye controlled HMDs – Head Mounted Displays – are actually the combined work of researchers at the Fraunhofer Center for Organics, Materials and Electronic Devices Dresden COMEDD, Fraunhofer Institute for Optronics, System Technologies and Image Exploitation IOSB in Karlsruhe and near-the-eye technologies specialist TRIVISIO.

“We’ve fitted our glasses with a novel CMOS chip with an integrated camera and OLED microdisplay, for which we also hold the patent,” explained Herold.

According to the organization, this is the first time that OLEDs are integrated with photodetectors onto the surface of the CMOS chip of dimensions 11mm x 13mm. Chip has four OLED pixels to render images on the microdisplay with photodiode in the center to read the eye movements. Photodetectors work as a kind of camera with a light field measuring 10.24 by 7.68 millimeters.

“The chip is equipped with microscaled transmitter and receiver units that configure the pieces of information sequentially; we call this an array structure. This gives us a bidirectional microdisplay, making it possible both to record and to reproduce images,” said Herold.

These glasses will be presented in the form of an Evaluation Kit at the joint Fraunhofer booth in Hall A5, Booth 121, at the electronica trade fair in Munich, from November 13–16.
