Touch – the Link between Man and Machine

A brief touch with your finger is all it takes to activate the full functionality of a capacitive PolyIC sensor touch screen. But what is behind this spectacular touch technology? A transparent PET carrier that serves as the basis for conductive metal mesh structures. Unique in shape and patented under the name PolyTC® for touch screens. With outstanding properties such as high transparency and electrical conductivity, PolyTC® touch sensors are ideally suited for the use of touch screens in a wide range of sizes. This allows you to create innovative control elements for the Human-Machine Interface (HMI).

 

Benefits of PolyTC® Touch Screens at a Glance:

  • Thin, flexible sensor foils
  • High transparency thanks to PET carrier
  • High conductivity due to metal conductors (metal mesh)
  • Individual layouts and sensor systems possible
  • High quality, even with large quantities
  • Can be combined with IMD (In-Mold Decoration)
  • High availability through roll-to-roll production

Touch Screens for Your Application:

  • Smartphones
  • Tablets
  • Laptops
  • Navigation systems
  • Information and control displays
  • Screens for all types of devices

Multitouch – Freedom in Form and Function

Our capacitive PolyIC sensors for touch screens are the basis for any modern, interactive input device. This makes it easy for your customer to tap, zoom, or swipe on their touchpad. Our PolyTC® sensors impress in your desired format with the highest quality and optical transparency. What’s especially attractive for you is that we produce our touch screen sensors in a cost-effective roll-to-roll process, allowing you to take new functional and aesthetic paths.

 

How Are PolyTC® Sensors Integrated into Touch Screens?

The integration of touch sensors is an important part of the entire production process. As a long-standing sensor specialist, we are at your disposal with expert advice for your individual product. We will inform you about the various integration methods and what new possibilities are available to you.

Lamination with OCA/PSA

Precise applications – with post-treatment if necessary – are the key to safe results in the lamination process. This prevents unwanted blistering and increases the adhesive strength. We offer PSA (Pressure-Sensitive Adhesives) for standard qualities, e.g., illuminated symbols. However, if your product has particularly high optical requirements, such as touch screens on flat glass substrates, we recommend the use of OCA (Optical Clear Adhesives).

In-Mold Labeling (IML)

Injecting a sensor via In-Mold Labeling (IML) enables you to perform a ‘one-shot process’ in which the component is sprayed together with the sensor label. If required, the decoration can even be directly integrated here – e.g., in the IMD process. The IML process for sensors is often referred to as IME (In-Mold Electronics). Here you can experience all the benefits of a fully integrated process.

Functional Foil Bonding

Reinventing Touch Screen Integration

The lamination process is traditionally used for the integration of touch sensors. If you’re after more flexible, precise, and at the same time faster results, give FFB (Functional Foil Bonding) a try. This process revolutionizes sensor integration for components with complex geometries, such as those found in the automotive sector.

Your Advantages of FFB for Touch Screens:

  • For flat, curved, or lightly 3D shaped components
  • Mature process in series production
  • Lifting or unwinding procedure possible
  • Precise sensor placement possible with full automation
  • Adherent, stable connection with touch screens
  • Optimum adhesion during climate change test
  • Cost reduction through waste reducing post-mold process

Set New Standards with Touch

Intuitive, convenient operation, maximum design freedom, and even greater hygiene – modern single-touch and multi-touch screens provide end users with plenty of benefits. Whether it's home appliances, home automation, automotive, or consumer electronics, with PolyTC® sensor technology you create innovative operational controls for the Human-Machine Interface (HMI).
