Touchscreens for public unguarded areas

As a specialist for touchscreen vending machines and kiosk systems, we have many years of experience in meeting the requirements of reliable vending machines.

Self-service terminals with touch screens, for example in the form of ticket machines, parcel stations or interactive information terminals, have become a familiar sight in public spaces.

Customers benefit from the elimination of opening hours, fewer queues and the intuitive operation of such POS and POI systems.

For service providers, these systems are an efficient way to increase profits and save personnel. However, kiosks in publicly accessible, mostly unguarded areas are always exposed to a high risk of vandalism.

Interelectronix offers touchscreens of the highest robustness for such applications, which can withstand the impact of force from objects or blows. At the same time, they are chemically resistant, so that even strong, deliberate soiling does not destroy the surface and can be removed.

Robust glass surface

The decisive factor for the robustness of a touchscreen is the surface structure. Interelectronix works with three different variants that reliably protect a touchscreen from violence:

  • Microglass in different thicknesses
  • Chemically tempered substrate glass
  • Laminated glass on the back.

When deciding on the right glass variant, the chosen technology plays a major role in addition to the area of application.

##MICROGLAS

We achieve the best results in terms of robustness with our resistive ULTRA technology. Under certain conditions, PCAP touchscreens are also well suited for use in publicly accessible applications.

##Entscheidend is the surface

The top layer of our GFG ULTRA touchscreens is a very thin borosilicate microglass as standard. We offer microglass in two thicknesses, whereby the thinner version of 0.1 mm usually offers sufficient protection against vandalism.

##VERBUNDGLAS

A slightly thicker laminated glass is placed on the back of the touchscreen and provides additional protection against vandalism. The decisive factor in this design is that even the outermost layer resists a certain application of force and that no free splinters can occur.

Different glass thicknesses are available for the laminated glass, all of which can withstand a force of at least 5 joules.

In addition to the noticeable improvement in robustness through the use of laminated glass, Interelectronix achieves a noticeable improvement in impact resistance through additional damping under the laminated glass.

##CHEMISCH TEMPERED SUBSTRATE GLASS

Chemically hardened substrate Glass is both an impact-resistant and thin variant that can be used as a front panel for touchscreens in vandal-prone areas.

Especially for projected capacitive touchscreens, chemically tempered glass substrates are an optimal solution to guarantee multi-touch function as well as impact and scratch resistance in equal measure.

No chance for rioters

Our patented ULTRA technology is predestined for use in public areas thanks to a very resistant structure. Even deep scratches do not affect the functionality of the touch panel.

But our projected capacitive touchscreens can also be optimally protected against the effects of force.

If no multi-touch function is desired, we can even install front glass up to 20 mm thick in self-capacitance systems. With this very thick glass thickness, however, restrictions on the touch reaction are to be expected.

The multi-touch function is possible without restriction for lenses up to a thickness of 2 mm. The functionality of a touch sensor is only impaired by extremely deep scratches in the glass.

With chemical hardening of the glass, however, such damage can be almost completely ruled out with both PCAP and GFG touchscreens.

##Beste Test results

In the bullet drop test, Interelectronix 's patented ULTRA touchscreens in particular achieved optimal results. Even the standard ULTRA touchscreen withstands a load of 5.74 J without the use of specially tempered glass or extra thick front glasses.
