Displays and smart surfaces

Electronic masterpieces enable the vehicle of the future to become a living organism on the inside. Reflective surfaces turn into transparent, interactive control panels. The vehicle communicates with occupants using light signals on previously immaculate surfaces. The future of interior design for vehicles is in the midst of a revolution.

Smart surfaces & displays – Inspire and surprise customers

With intelligent surfaces such as SKINTEC® or KOSTAL protec®, the vehicle seemingly comes to life. The control surfaces are adapted to the design contours. The symbol brightness is adjusted to the ambient light to create a day and night design, adding to the overall high-quality feel. 

KOSTAL's smart display approach, with powerful local graphics and processing power thanks to the HMI integrated in the armrest, offers the flexibility and performance that the end customer expects and that also respond to industry trends.

Switch panels

Top-quality surfaces, difficult illumination conditions and low and uniform gap dimensions are only a selection of challenges for switch panels that are optimally solved with KOSTAL product and process technologies. Our solutions are based on more than 70 years’ experience in the development and production of switch panels and switches for the automotive industry.

Switch panels – Customer-specific development

In line with the customer's requirements profile, KOSTAL provides fully configurable module and platform concepts for switch panels. KOSTAL development systems use proven, standard technologies and integrate these into new installation situations and surface designs.

Production facilities with globally valid standards ensure a high degree of flexibility in the planning of production sites, taking into account the respective customer requirements.

Virtual modularisation in design leads to customer-specific and cost-optimised solutions, with predictable high quality and short design and installation times.

Roof modules

Roof modules combine a wide variety of individual components in a single module. KOSTAL's expertise in switch panels, mechanical, electronic and software development, lighting technology, simulation techniques and manufacturing technology make it the ideal partner in the development of optimum-interface roof modules.

Roof module with touch functions

KOSTAL roof modules serve as a gateway for communication between the vehicle world and local subsystems. Sensor signals, for example from the self-dimming mirrors or rain/light sensor, are processed in the roof module.

They are also a key component of modern HMI concepts, in which the roof module can handle a variety of functions and displays with a high degree of integration and is extremely well embedded in the driver experience.

To optimally support your future HMI concepts in combination with future-proof design, KOSTAL offers the option of integrating state-of-the-art sensor, lighting and surface technologies in roof modules.

Many brands in a wide range of vehicle segments trust in KOSTAL roof modules. You will find KOSTAL roof modules in following brands Mercedes Benz, Porsche, Volkswagen, Skoda, Seat, Bentley, BMW and General Motors, among others.

Rain/light sensor

The portfolio is complemented with the 7th generation stand-alone rain/light sensor which is remarkable for its extremely compact dimensions, allowing it to be incorporated in the base of the mirror and due to its colour it is well harmonized with the windscreen. It also includes the driver-monitoring camera. This camera operates in the interior of the vehicle and checks the driver’s head and eyelid positions, thus detecting his or her attention level. In future, where piloted steering is installed, this will allow the driver to take his hands from the steering wheel.

  • Proven KOSTAL performance of previous generations
  • Optimum dimensions for integration at the base of the mirror
  • Scalable: includes solar, fogging, and ambient light (HUD) sensors as options
  • Uniform black footprint on the windscreen
