Robust touchscreens for a wide range of applications
Applications in unattended publicly accessible places such as ATMs, ticket machines or kiosks require special robustness due to the risk of vandalism.
A high impact resistance and robustness can be achieved with touchscreens through:
- different thicknesses of external microglass
- chemically hardened substrate glass
- Laminated glass on the back
Microglass thickness for extreme use
The top layer of our GFG touchscreens is a very thin glass. This glass, despite its thickness of only 0.1 mm, is very impact-resistant, scratch-resistant and waterproof.
In addition to the basic structure, the thickness of the outer microglass of the GFG Glass Film Glass Touchscreen can also be varied.
Interelectronix offers a choice of two variants of microglass thickness:
- 0.1 mm (standard) or
- 0.2 mm (extra robust).
We recommend doubling the glass thickness to 0.2 mm, especially for touchscreens that are subject to extreme stresses.
The thicker version is even more robust than the standard version, but the activation force required to trigger an impulse increases. This may well be desirable in individual cases if the touch control is not allowed to react too sensitively to a non-specific pressure.
The scratch resistance is identical in both glass thicknesses. However, the 0.2 mm variant achieves better impact resistance (vandalism) as well as higher thermal resistance, which is quite advantageous in industrial environments such as welding, flexing and handling liquid metals.
GFG laminated glass for public kiosks
A GFG resistive touchscreen in public places can be very well protected against vandalism by being equipped with laminated glass. Here it is crucial that the outermost layer resists a certain force and that there are no free splinters in the event of damage to the surface (risk of injury).
The equipment of a GFG glass film glass touch panel with laminated glass is possible in two thicknesses:
- C16 with 1.6 mm
- C30 with 3.0 mm
The C30 version can withstand a force of at least 5 joules (5+). This corresponds to a 500g steel ball hitting the glass pane from a height of one meter.
In order to increase the impact resistance even further, the laminated glass Interelectronix installed with an underlying damping.
GFFG - lightweight and robust
A very good compromise between thickness and impact resistance is our GFFG glass film film glass variant with chemically hardened substrate glass.
This solution is even more robust than the usual GFG design and ideally suited for demanding applications where the touchscreen must be very robust and at the same time very thin and light.
Mobile applications in handhelds or tablet PCs, which should also be resistant due to the higher risk of falling, are ideal areas of application for the GFG setup.
