In addition to an energy-saving design, microdisplays for wearables must also display information in a way that they are sufficiently bright under daylight conditions, at best in colored versions and recognizable with the naked eye. The OLED microdisplay family of the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has now been extended: Microdisplays in a new design for ultra-high brightness. The new versions will be presented for the first time at the SID Display Week, May 10 – 12, 2022, in San José, USA, booth 1320 (German Pavilion).
Small, ultra-low power, high-contrast OLED microdisplays are ideal for head-up systems or wearables. They are used in industries like logistics, displaying information on employee helmets, or navigation in various environments. Fraunhofer FEP has advanced ultra-low power variants, offering longer battery life and higher brightness. Available in monochrome, dual-color, or warm-white, these displays reach brightness levels from 5,000 to 35,000 nits, making them suitable for outdoor or firefighting helmets.
Fraunhofer FEP offers customer-specific microdisplays, from CMOS development to system integration, with evaluation kits for initial testing. Their OLED microdisplay portfolio now includes ultra-low power and full-color video displays, achieving up to 35,000 nits. The 720p display reaches 1,000 nits for AR applications, while dual-color versions hit 5,000 nits. This brightness was achieved by developing new OLED stacks and filter technologies, balancing brightness and content quality.
The working group for microdisplays has moved to Fraunhofer IPMS.
