What Makes a Touch Screen Vandal-Proof?

A vandal-proof touch screen combines toughened glass, a touch technology that works through that glass, and a sealed, rigid housing. Its resistance to impact is measured with an IK rating: IK07 withstands a 2 joule impact, and IK10 withstands 20 joules. Stainless steel or aluminium enclosures and hidden fixings finish the job.

The Short Answer

Projected capacitive touch senses through glass, so the glass can be thick and toughened without stopping the screen working. Resistive screens have a soft top film that can be cut or scratched more easily. In heavy industry, the same protection guards against accidental knocks from tools and equipment as much as deliberate damage.

  • //
    An IK rating IK07 or higher on the front glass for exposed locations.
  • //
    Toughened glass Strengthened cover glass that resists cracking and scratching.
  • //
    A sealed front No gaps or bezels to pry, ideally with an IP65 or higher rating.
  • //
    No exposed ports I/O underneath or on locking connectors, with tamper-resistant fixings.
