➀ Fraunhofer Institute for Photonic Microsystems has developed hardware and software to interface its OLED micro-displays to various input interfaces, named as 'Universal Display Data Converter' or UDDC. ➁ The micro-displays are designed for augmented and virtual reality headsets, serving as a development tool and design example. ➂ UDDC converts various standard video interfaces to a standard for driving different microdisplays, and can adapt to video sources already available in systems.
