Sci-fi surfaces activated by touch and made to awe
Large 3D displays or touchscreen panels are more than a trend. They’re the future of car interiors, and engineers must continue to evolve these technologies to stay competitive. Our polycarbonates offer high resistance to a range of temperatures, superior mechanical properties and high transparency.
Tech-oriented buyers prioritize the cabin experience
After taking a backseat for the past couple of decades, car interiors are now in sharp focus for both OEMs and consumers. Trends such as automation, connectivity, electrification and shared services have forever changed the way cars are configured. They’ve also whet consumers’ appetite to enjoy new in-car experiences. On their must-have list: futuristic human-machine-interface (HMI) systems.
Tech-oriented car buyers have come to expect new vehicles to dazzle them with large interactive display screens and haptic surfaces that make for a great user experience. These displays can do everything from direct drivers to their destination, to warn them of accidents or delays ahead; they can be used to tweak the vehicle’s onboard systems, like the lights, or the temperature, or even to keep tabs on passengers’ health.
Today’s drivers are seduced by gently curved surfaces, tablet-like black screens, 3D projected displays and elements that only become visible when required. And these features generally aren’t shrinking violets. Drivers prefer prominent displays that enable a safer, smarter and sexier driving experience.
As vehicle interiors evolve, however, engineers who are challenged with bringing these displays to market face numerous challenges along the way. They must ensure all new innovations meet expectations for performance, design and functionality. That means delivering nothing less than high-performance, dimensionally stable display frames and casings, and scratch-resistant surfaces that are both high purity and low weight. Specially made for automotive interiors, Covestro’s Makrolon® Ai polycarbonate meets all of these standards and then some.

Makrolon® Ai — Covestro’s automotive interior grade polycarbonate — is driving car displays into the future.
Wow-worthy 3D displays, touchscreen technologies and black-until-lit screens are making many mechanical knobs and switches obsolete. Creating complex displays with capacitive touch function also requires enormous ingenuity on the part of design engineers.
With Makrolon® Ai — a high purity optical polycarbonate — engineers can enjoy maximum creative freedom without constraints. Bringing both form and function to the table, Makrolon® Ai display technology delivers a glass-like appearance as well as the highest level of functional integration with HMI systems and other integrated sensors.
Our transparent Makrolon® Ai creates the highly desired black panel effect, but this polycarbonate can also be used to unleash the power of brilliant colors in various degrees of transparency and translucency. And the options don’t end there — this polycarbonate can create micro texture patterns and even the look of a metal surface.
Makrolon® Ai can also be used to go beyond conventionally shaped display designs, bringing even XXL screens to life.
Fast track in-car display innovations with Covestro
Need to put the pedal to the metal on development speed? Partner with Covestro. When they choose Makrolon® Ai, OEMs aren’t just choosing a high purity material that makes mass production feasible, they’re also gaining access to an entire ecosystem of technology partners globally. Everyone from mold makers to machine manufacturers to adhesive and optical bonding suppliers, coating suppliers and more are available to help our partners navigate from prototyping through to full production.
For example, when help is desired, we offer in-house color matching services. And our in-house coated film solutions ensure surfaces are protected and optical requirements are met.
Scalability, viability and speed are also critical, as interior displays need to be ready to be mass-produced as soon as possible. With regard to regulatory safety, Makrolon® Ai has been tried and tested. And our high-efficiency processes ensure low scrap rates and affordable production costs.
Our job: to mind every little detail so design engineers can concentrate on their next big, brilliant idea. What do we mean by thinking of everything? Whether it’s regulatory safety requirements and head impact risks in the case of an accident, or common processing and application challenges such as glare, reflection, weathering, scratches and abrasions, or how important it is to have material that’s both globally available and inter-changeable, we’re focused entirely on development execution speed, cost savings, safety and collaboration.
Partnership with Covestro means confidence in what you’re creating.
“The options for large in-cabin displays are really endless — the possibilities with 3D, eye-level projections are especially exciting — and our highly transparent and high purity Makrolon® Ai polycarbonate is made to keep design engineers dreaming big and turning possibilities into real products. Among the types of technology it enables, we’re seeing XXL sizes, curved 3D shapes, safety-replacing glass components, optical performance, touch, sensors and cameras, aesthetic surface design patterns, back-lit multi-material surfaces and more.”
