Touch Input Devices

For design-oriented applications and input devices  we offers capacitive keyboards and touch panels.

In the field of touch panels, we offer resistive and capacitive touchscreens both as a single product or as an integrated solution with a customer-specific membrane switch .

You can find TFT Displays with Touch-Function in our optoelectronics product range  >>

We offer customized touch panels in many sizes.

Also an individual printing of the frame in possible.

Function
Advantages
  • Comparatively cheap
  • Insensitive to dirt, dust and moisture
  • Use with fingers, gloves and other items
  • very high transparency and visibility
  • Multi-touch effect: the screen can be operated with up to ten fingers at the same time
  • more resistant to liquids, chemicals and dirt and easy to clean
  • due to different cover glasses also vandal-proof versions possible
Disadvantages
  • Softer surface is needed for pressure release
  • lower light transmission and lower contrast
  • less resistant to chemicals
  • no multi-touch function possible
  • Operation only possible with fingers and especially conductive pins
  • Costly
Application Point of sales terminals, building automation, medical technology Smartphones, Tablets, Organizer

For design-oriented applications and input devices  N & H Technology offers capacitive keyboards. They are realized by an electrically conductive surface, such as glass, metal or plastic. These capacitive sensors simulate the input fields. The change in capacitance of the electric field takes place by touching or approaching the finger. Unlike membrane switches no tactile feedback takes place. However, these can be replaced by an acoustic or optical signal. Capacitive Keyboards can be made in various keys forms and shapes. Operating modes such as Slider, Wheel and touchpad can be added.

Metal over Capacitive (MOC)

Through a new, touch-sensitive sensors, capacitive input solutions with metal fronts made of stainless steel or aluminum are possible. A very sensible sensor recognize a deformation of the surface. It can be used with gloves and is extremely resistant to environmental influences. Plastic surfaces or combined surfaces of plastic and metal are possible.

Touch panel with membrane keyboard

Especially for ​​HMI devices, membrane keypads with integrated touch screens can make user-friendly menu navigations. Input commands or preset parameters can be easily and clearly accessed. Thus, even complex menu controls with submenus can be solved in a user-friendly way.

For a touch screens version, windows can be integrated into the membrane keyboard. Depending on the requirements, these windows can be specified glossy, matt, anti-glare, scratch-resistant, UV-resistant and colored.

The combination of membrane keyboard and touch screen is realized by a highly transparent adhesive layer with a light emission of> 99%.

This process avoids the formation of Newtonian rings. The bonding takes place in clean rooms.
