Each pixel measures 40 x 40µm, and can be individually tuned to form different beam shapes for different road conditions.
“It also provides dynamic curve light and precise glare-free high beam block-out zones to avoid blinding on-coming drivers,” said Marelli. “Furthermore the ‘h-Digi microLED’ can project warnings or driver assistance images on the road in the driver’s field of view.”
This is Marelli’s second generation of high-resolution projection system, following the 2018 digital micro-mirror-based ‘h-Digi’, which can be found in some premium-level vehicles.
The LED array is Osram’s Eviyos 2.0, designed for automotive use, and Marelli designed the associated optics.
Osram also produces a companion asic for driving the micro-LED matrix, that has UART, RGB8 and SPI/CSI video options.
“High-resolution adaptive forward lighting is set to become the next big differentiator for vehicles from the world’s premium brands,” said Osram v-p Wolfgang Lex.
“The module enables us to develop solutions for global car makers – the system opens doors to applying the technology also in mid-level car segments,” said Marelli v-p Didier Thalgott.
