Osram Opto Semiconductors is taking part in this project together with ASM AMICRA and Fraunhofer IISB with the aim to push μLED-based high-resolution visualization solutions into automotive interior applications. μLED technology can produce extremely high luminance in a wide dynamic range, and imaging devices based on direct emitting μLED pixels are considered a disruptive development in the visualization market, with the potential to sideline technologies such as LCD or OLED.
Over the next two and a half years, the SmartVIZ research project aims to provide the basis for future transparent, high-resolution, direct-emitting visualization solutions using μLED technologies.
The envisioned work packages will focus on three key technologies. First, the design of efficient μLED light sources, second, their handling on sub-component level and third, the final assembly. Red, green and blue μLED structures will perform as efficient high luminance image pixels. Implementation of such concepts and applications requires in-depth studies of the underlying physical principles that are in-part entirely different than today’s macro LED chips.
The project will also conduct research addressing the component integration of μLEDs using a novel approach for transparent and flexible image encoders. Transparent substrates based on indium gallium zinc oxide thin-film transistors (IGZO TFTs) will be the researchers’ focus for controlling the individual pixels. This approach allows for quasi-transparent surfaces, which can be filled with content only if the μLEDs are switched to active.
