Hardened Armored Touch Screen Technology



AbraxSys' Hardened Armored Touch Screen technology is a glass armored resistive technology and is an excellent alternative to standard resistive when durability is an issue. This ruggedized touch screen is a proven technology deployed in thousands of applications worldwide.

A micro-thin sheet of borosilicate glass is laminated to the ITO polyester top sheet used in the typical construction of resistive touch sensors. This process produces a flexible glass membrane which is scratch resistant, water proof and impervious to chemicals, fire and stylus use. The resulting touch sensor is ideally suited to Military, Industrial, Mobile, Public Kiosk and Medical applications. Configurations are available for 4, 5, and 8 wire sensors from 5″ to 24.0″.

•  Abrasion and scratch resistant;
•  Water proof and impervious to flames, chemicals, solvents etc.;
•  Maintains all typical benefits of resistive technology;
•  Expanded operating environmental window. Can operate where no other technology can;
•  Lasts longer due to the stiffer glass/polyester top layer which reduces ITO fracturing failures including
   damage from stylus use;
• Reduced pillowing possibility of the top layer as glass/polyester lamination has a closer expansion/contraction
   coefficient to the substrate glass;
•  The glass/polyester top layer does not shatter and allows the sensor to continue to operate even after
   extreme abuse such as deep scoring, repeated impact trauma and other vandalism;
•  If the substrate breaks, the broken glass shards are safely held behind the glass/polyester top layer which
    will remain intact. 

With such a durable outer layer, AbraxSys' Hardened Armored Touch Screen technology lends itself to implementations that will be exposed to extreme abuse. Applications such as the battlefield, public kiosks that are prone to vandalism, systems deployed into heavy engineering or mining environments, general ruggedized equipment, etc. To meet the demands of these kinds of applications AbraxSys has developed with its touch partner a process to laminate various backplane substrates to the Hardened Armored Touch Screen sensors:

•  3mm thick true safety laminated pure glass fronted
   construction optically bonded overlay with Anti-Reflective
   Field

•   Thermally Strengthened Glass Substrate with UV Protection

•  Antireflective treatment with specially formulated ultra
    hydrophobic topcoat to eliminate “smudging”, for better water repellence as well as resistance to dirt, oil,
    watermarks, and other environmental influences

•  High Accuracy

•  Image Stability - Not susceptible to problems caused by high-level short-term variances and axis linearity
    and drift

•  Contamination-resistant. Top sheet hermetically sealed with pressure sensitive adhesive with a 30 year
   rating. Unaffected by harsh cleaning fluids and other noxious substances

•  External environments – unaffected by dirt, moisture and rain

•  AR <= 0.5% Photopic Reflection, a vacuum deposited antireflective optical coating that is applied to the
   outer surface of the sensor armor glass. It has a relatively high temperature process so the coating is very
   durable and is designed to meet industry standards such as SAE AMS-2521 and MIL-C-675.

•  Scratch resistant hi-res anti-glare hard coat with 4h hardness

•  Activation with finger, stylus, gloved hand or any other pressure activation
