OLED microdisplay based eyetracking HMD

The Fraunhofer IPMS has worked on the integration of sensors and microdisplays on CMOS backplanes for several years now. For example the researchers have developed a bidirectional microdisplay, which could be used in Head-Mounted Displays (HMD) for gaze triggered augmented-reality (AR) aplications.
The chips contain both an active OLED matrix and therein integrated photodetectors. The combination of both matrixes in one chip is an essential possibility for system integrators to design smaller, lightweight and portable systems with both functionalities.
Rigo Herold, PhD student at Fraunhofer IPMS and participant of the development team, declares "This unique device enables the design of a new generation of small AR-HMDs with advanced functionality".
The OLED microdisplay based Eyetracking HMD enables the user on the one hand to overlay the view of the real world with virtual contents, for example to watch videos at jog. And on the other hand the user can select the next video triggered only by his gaze without using his hands.
Technical specifications:
  • Monochrome
  • Special Eyetracking-Algorithm for HMDs based on bidirectional microdisplays
  • Front brightness: > 1500 cd/m²
Fraunhofer IPMS, Dresden carries out customer specific developments in fields of microelectronic and micro systems technology serving as a business partner that supports the transition of innovative ideas into new products. Fraunhofer IPMS develops and fabricates modern MEMS and OLED devices in its own clean room facilities. In addition to R&D services it offers ramp-up within a pilot production. With modern equipment and about 200 scientists and engineers, the range of projects and expertise covers sensor and actuator systems, microscanner, spatial light modulators, wireless microsystems as well as organic materials and systems.
