It is difficult to imagine the entertainment and gaming sectors without data glasses and the associated virtual and augmented realities (VR and AR). But those are not the only sectors where they are being used. Data glasses are being increasingly employed in professional realms as well, offering designers, mechanics, surgeons, and first responders assistance with their tasks. Data glasses can also be employed as a teaching medium in nearly all fields.
To achieve high user acceptance, it is necessary to offer excellent imaging quality, and this in turn is where the high-resolution displays developed at Fraunhofer FEP are essential. Extensive experience as well as technological and process know-how enables them to develop and fabricate OLED microdisplays suited to a diverse range of applications.
An existing demonstration sample was modified together with the junior professorship of technological design at TU Dresden in such a way that it can be employed for AR as well as VR applications. With standardized HDMI and USB interfaces, the data glasses can be utilized with practically every video source. As a result, clients are able to evaluate various applications using the identical hardware.
“We not only can show the quality and versatility of our microdisplays with this demonstrator, it provides proof of our know-how in the area of electronic design,” developer Judith Baumgarten from Fraunhofer FEP explained.
The scientists utilized bidirectional microdisplays with a resolution of 800x600 pixels for this first demonstrator, integrating photodiodes on the chip besides the OLED pixels. In this way, the eye of the user can be recorded in addition to information being displayed, potentially making an eye-tracking system feasible.
