Touchscreen solutions by Hoffmann + Krippner - the perfect ideas for every industry

Graphic user interfaces via display have become quite common in consumer electronics. The technology opens up new and simple operating concepts even for industrial operations.

Due to their functionality and flexibility, touchscreen solutions have become more popular for industrial applications such as automation, medical technology as well as automation systems or information terminals.

 

Resistive touch screens by Hoffmann + Krippner

The resistive touch screens by Hoffmann + Krippner consist of transparent, conductive, cushioned layers. Even light pressure applied to the screen surface triggers the operating function. A small controller unit monitors the touch screen and relays the key actuation. The connected computer always knows where something is happening on the screen and can react accordingly - precise to the millimeter.;

The standard touch screen by Hoffmann + Krippner is available in many functional and design variations, as an individual component or integrated into keyboards with complete electronics. Customer-specific solutions are feasible from prototyping to large-scale production.

Capacitive touch screens (PCT a. PCAP)

Among the capacitive touch screens, three different types are available. Nowadays, most are so-called Projected Capacitive Touches - also known as PCT or PCAP. These consist of two isolated conductive layers stacked on each other, printed with a manufacturer-specific pattern, which is basically a large number of small capacitors. When the finger approaches or touches the interface, electrical charge is withdrawn from the circuit which is detected as a contact. 

The advantage of PCT compared to the surface capacitive touches is that the touch sensor may be mounted on the back of the cover glass and the capacitive areas are projected through the glass. This technology provides a more durable construction, effectively preventing vandalism.
