As automotive interiors trends evolve toward seamlessly integrated controls and adaptive design elements, manufacturers are seeking ways to embed smart functionality into surfaces without changing the look and feel of established materials.
Marquardt, a leading supplier of smart mechatronic systems for automotive applications, set out to address this challenge with its concept car, “The Centum”. A key objective in The Centum project was to develop a door interior panel that maintained the visual and haptic properties of polyurethane (PU)-coated textile synthetics commonly used in automotive interiors, while enabling a dynamic color-changing responsive display to be invisibly embedded within the surface. This functionality supports emerging trends such as backlit surfaces and integrated control elements.
To realize this vision, Marquardt partnered with E Ink, a leader in advanced display technology known for durability, low energy consumption, and suitability for demanding environments. The challenge was to integrate the functional display into the interior design in a way that preserved the premium appearance and performance of coated synthetic surfaces, while allowing the display’s colors to remain clearly visible.
After evaluating multiple approaches, Marquardt approached Covestro to develop a suitable material solution. Covestro textile coating experts worked closely with both partners to develop a fully transparent film based on INSQIN waterborne PU technology, with Impranil DLC-F as the foundation. Impranil DLC-F is a waterborne polyurethane dispersion widely used in topcoats for automotive interior textile coatings. The result is a transparent coated synthetic that retains the premium texture of automotive textiles while allowing the display’s dynamic colors to be fully visible, fulfilling the demanding performance requirements of automotive interiors.
Felix Hake, Head of Innovation at Marquardt said: “With The Centum, we wanted to demonstrate how intelligent functions can be integrated into interior surfaces without compromising design or quality. Working with E Ink and Covestro allowed us to create a material solution that combines a premium tactile experience with responsive visual effects.”
Dr. Torsten Pohl, Global Head of Textile Coatings at Covestro added: “This project highlights the versatility of INSQIN PU technology and Impranil DLC-F. By developing a transparent, automotive-grade PU coated synthetic compatible with E Ink displays, we were able to support Marquardt in integrating dynamic functionality into familiar surface materials.”
Pete Valianatos, Senior Director, Strategic Initiatives & FPL Platform Management at E Ink, noted: “Our e-paper display technology is designed to deliver dynamic visual experiences with low power consumption, while maintaining the robustness required for demanding applications. Collaborating with Marquardt and Covestro has enabled us to demonstrate how E Ink displays can be integrated behind coated interior surfaces, allowing automotive designers to introduce adaptive color features without changing the established look and feel of premium materials.”
