NIR-OLEDs integrated into CMOS silicon chips
Achievement "opens up completely new applications for the already commercially successful OLED-technology."
For the first time ever, the Center for Organic Materials and Electronic Devices Dresden (COMEDD) at the Fraunhofer Institute for Photonic Microsystems has successfully integrated Near Infrared OLEDs into CMOS-silicon chips. A key capability of this achievement is that they can be used as a light source in various fields of sensor technology, such as for medical light therapy or in a display. The technology will enable, for example, the development of NIR-OLED based light barriers or flow sensors.
”The successful development of organic light emitting diodes, which emit in near infrared spectral range, opens up completely new applications for the already commercially successful OLED-technology,” commented Uwe Vogel, Head of Business Unit Microdisplays & Sensors at COMEDD.
By combining NIR-OLEDs with conventional OLEDs, light systems with an accordingly extended spectral range can be produced for color sensors or spectrometers. NIR-displays could be applied, for example, in night vision devices fitted with supporting low-light amplifiers. The displayed information would remain invisible to anyone but the operator of the device.
