Which touch technology is the right one?
Not all touchscreens are the same. Although many consumers consider the iPhone to be synonymous with touch, there are, however, numerous differences to consider. Especially for industrial applications, the various technologies should be examined more closely. Various requirements such as special design, safe and reliable operability, technical features, long availability and a reasonable price have to be accommodated. Now

Components and options
Touch systems with cover glass
For the cover glass, a standard float glass is tailored entirely to the touch system’s area of application: a glass surface with anti-reflective coating for improved visibility and a hardened surface for robust applications. Glass printing, perforations, chamfers or finger recesses can be implemented individually according to customer requirements.
Touch systems with foil
You can choose between a smooth, textured or UV-stabilized (for outdoor use) surface for the decorative film. Design, openings, transparent windows and finishes are realized individually.
Ball drop test according to UL-60950
To ensure that your touch system always works reliably, we can also carry out ball drop tests on request. In our video we show a ball drop test according to UL-60950 using an industrial touch system with a chemically hardened 2 mm cover glass.
Touch Systems with Membrane Switches
Both resistive and capacitive touchscreens can be combined with a membrane switches. For applications that require haptic feedback when a key is pressed in addition to touch technology, the touch system is expanded to include membrane switches.
Touch Sensors for Touch Systems
The heart of the touch system is the touch sensor. Together with you, we select the appropriate sensor, capacitive or resistive, and connect it to the remaining components. In the clean room, the touchscreen is bonded to the cover glass or decorative film with a highly transparent adhesive.
Displays for Touch Systems
There are several influencing factors to consider when selecting the optimal display. Is the control unit used outdoors? Is the display glued or screwed? What resolution must be guaranteed? Should a touch sensor be integrated?
Together with you, we select the appropriate display. The display can be bonded to the glass or touchscreen dust-free with the in-house optical bonding process.
Touch Systems with Optical Bonding
For a brilliant image, we bond touchscreens with displays and cover glasses using the optical bonding process. We rely on two proven bonding techniques: LOCA and OCA bonding.
Touch Controller for Touch Systems
The touch controller takes over the entire processing for the touch screen. It can be integrated directly on the connector tail of the touch sensor (chip on tail) or assembled on a separate circuit board.
We will gladly take over the programming for the touch sensitivity settings for you.
Touch Systems with Housing + Carrier
For optimal mounting of the touch system in your application, we recommend integration on a carrier plate or housing. These give the control unit more stability and simplify installation.
For increased requirements, we supplement the system with an appropriate seal. Individual seal contours can be dispensed with the in-house dispensing machine.
Gaskets for Touch Systems
We protect your touch system against external influences with individual gasket contours. With our in-house dispensing machine, a wide range of different types of gaskets can be dispensed. Dispensed front gaskets in black, white and transparent serve to seal the gap between the housing/front panel and cover glass

FAQ: Frequently asked questions about touch systems
Yes, touch systems can be customized to a high degree. Neben verschiedenen Glasstärken und Oberflächenbeschichtungen sind
auch Designanpassungen, wie die Glasbedruckungen möglich. Zudem können Funktionen wie Multitouch, Gestensteuerung oder integrierte
Beleuchtung realisiert werden. The result is a touch system that is individually tailored to the requirements and design of the end product.
The robustness of touch systems depends on materials and protective layers. Chemisch gehärtetes Glas erhöht die Beständigkeit gegen
mechanische und chemische Belastungen. Beschichtungen und Dichtungen nach Industriestandards gewährleisten die Funktion auch unter
extremen Umweltbedingungen.
Resistive touch systems are cost-effective, precise and can be operated with pens or gloved fingers. Sie reagieren
zuverlässig bei Verschmutzung oder Feuchtigkeit und bieten eine hohe elektromagnetische Verträglichkeit, was sie für industrielle
Umgebungen geeignet macht.
Yes, touch systems can be designed for outdoor use. Dazu kommen spezielle Materialien, Fertigungstechnologien (z.B. Optical
Bonding) und Oberflächenbeschichtungen zum Einsatz, die vor UV-Strahlung, Temperaturschwankungen oder Kondenswasser schützen. Auch
die Bedienbarkeit bei Regen oder mit Handschuhen lässt sich durch entsprechende technische Anpassungen sicherstellen.
