Shanghai, China, November 7, 2025 - AMS Osram (SIX: AMS), a global leader in lighting and sensing innovation, and DP Patterning jointly announced today the launch of a demonstration model showcasing the future development direction of automotive lighting systems: This demonstration model uses a single-layer flexible printed circuit board to replace the traditional complex multi-layer design. According to the Fraunhofer life cycle assessment report, in the production structure process, it can reduce CO2 emissions by up to 98% compared to the chemical wet etching process. This demonstration model combines the dry circuit board manufacturing process of DP Patterning with the advantages of AMS Osram AS1163 LED drivers. It not only presents an innovative technical concept but also has broad practical potential and can be easily applied to flexible circuit board scenarios such as automotive interior and exterior lighting and smart surfaces.

Ams Osram's Open Systems Protocol (OSP) offers greater freedom in design and effectively reduces costs. The new demonstration model adopts this protocol combined with the chemical-free dry process of Swedish technology partner DP Patterning, demonstrating the potential for developing more sustainable solutions in the future.This demonstration model can connect the leds, sensors and actuators inside the vehicle through a simple and continuous circuit, achieving independent control of hundreds of light spots. The independent intelligent driver (SAID) AS1163 enables medium and low power leds to be directly connected to the OSP network without the need for an external local microcontroller. This feature makes flexible and even single-layer circuit boards ideal choices for creating ultra-thin and compact lighting modules.
This demonstration model reveals the future trend of lighting networks: doing "subtraction" in chemical processes and complexity, and doing "addition" in the degree of freedom of single-layer design. Andrea Maria Saraceno, an application engineer at AMS Osram, emphasized.
Compared with traditional electronic circuit technologies that use etching grooves and silver paste printing, the dry Patterning (DPP) technology adopted by DP Patterning is a unique patented dry process - this process does not require water and does not involve harmful chemicals, and can be imagined as precise dry cutting of metal coatings. This process does not produce chemical wastewater, leaving only dry and recyclable metal residues. In addition, this technology simultaneously reduces energy consumption and process complexity. According to the Fraunhofer Life Cycle Assessment report, in the structured process, DPP technology can reduce the carbon footprint by up to 98% compared to wet etching.

For automotive interiors, this technology offers greater room for the development of ambient lighting and intelligent surface design. Whether it is a slender edge light band or a large-area curved light strip, a thinner, lighter and more flexible system integration can be achieved. This technology also brings positive impacts to society and the environment: it not only effectively reduces energy consumption and eliminates wastewater pollution, but also supports local production, thereby shortening the supply chain.Please click here to learn more about the AMS Osram Open Systems Protocol (OSP).
DP Patterning will showcase this demonstration model at booth B2/506 of the International Electronic Production Equipment Exhibition (productronica) to be held at the Munich Exhibition Center in Germany from November 18th to 21st, 2025.
