Touch Technology in the Great Outdoors

Outdoor applications for Touchscreens

Touchscreen technology forms part of our everyday lives. From the Pay at Pump petrol stations to withdrawing money from a cash machine. The demand for the everyday touchscreen is far greater than ever before as users want an instant response and the quickest way to get it, bringing the touchscreen at the forefront of businesses strategies.

Advantages of Touch Technology

Adaptability:  Investing in capacitive input systems can pay dividends. If you were to replace a membrane keypad parking machine, when a new design comes to market, it isn't as simple as just installing the new software. The entire unit would need redesigning. Whereas once you have invested in touch capacity, the only function that would need be to be updated is the software. Saving costs for your business in the long term.

Durability:  A membrane keypad has a lifetime of around one million presses. A touchscreen has no limit, the glass will last virtually until it breaks. With the design and technology used to manufacture the glass, it can withstand harsher working environments, a range of touch forces and weather tolerances. An option to ensure maximum durability is to review the thickness of the glass. Producing a product with thicker glass will ensure a longer lifespan, in turn also saving long term costs.

All Weather Proof

Rain: If sealed properly within the housing unit or enclosure, manufacturing a water resistant touchscreen is possible. It is key to note, although an input system can tolerate rain, if submerged in water the functions will not withstand. As water is a conductor, the touchscreen will interpret this as human interaction, therefore it will not work.

Sun: A touchscreen is no different from any other piece of glass. If left out in the sun it will heat causing it to become too hot to touch. A touchscreen can continue to function until approximately 70 degrees, however to touch this with bare hands would definitely cause a reaction from the user!

Cold: A touchscreen can still function with temperatures dropping to around minus 20. Even though temperatures like this are rarely experienced in the UK, it is a consideration SCHURTER takes into account when testing our touchscreen solutions.

Optical Bonding

Optical Bonding is the method in which the air gap between the touch and the display is removed. This process makes the touch and the display essentially one unit. Imagine gluing the display and the touch together, and light from the display only has the outside surface of the glass to overcome. A display without optical bonding will cause refraction and reflection due to the various layers of glass the light from the display has to penetrate.

Coating Treatments

Anti-reflective and anti-glare are coating treatments for a touch panel. By adding these finishes to the end product, they will reduce reflection from the sun in a similar way in which the glasses we wear are coated in an anti-glare treatment.

The method is key when designing touchscreens for outdoors and forms part of SCHURTER's overall customer requirements assessment.
