ZeykoAD chooses Zybrid touch sensors

The touch display systems are being installed in shopping hubs and in passenger concourses in the Seoul underground rail network.

Users can select from several features via the colour display, which presents touch-sensitive icons in an accessible layout.

Information available includes local maps, shopping plans and travel timetables, as well as details of restaurants and other facilities.

The terminals also provide internet access, as well as a VoIP phone handset allowing users to make phone calls by calling up a soft keypad on screen.

When not in use, the large display is able to present advertising, or other messages, which allows the operator to build extra sources of revenue.

To deliver this advance in styling and functionality, ZeykoAD sought a reliable, rugged touch screen solution in a 46in screen size, that was suited to bezel-free mounting enabling a pure glass, flat-fronted design, easy to clean and modern in appearance.

'By providing easy access to local information using durable touch sensor technology and modern smartphone ergonomics, we can help numerous types of providers to enhance delivery of services,' said Jung In Joo, chief executive of ZeykoAD.

'The bezel-free touch screen is central to our vision, and our evaluation identified Zybrid as the best possible solution.

'Only Zybrid was able to support the desired visual styles, as well as sunlight readability, extremely high resistance to damage - which is critical for an application situated in an unsupervised location - and wipe-clean capability,' he added.

Zybrid achieves high accuracy, durability and readability using Zytronic's Projected Capacitive Technology (PCT).

It uses micro-fine capacitors deposited in an X-Y grid array and then laminated behind a protective front surface, instead of conventional surface-active components, giving high light transmissions and allowing extra styling freedom.

As the sensing array is embedded it is well protected from both accidental and deliberate damage and will continue to operate even if the front panel becomes scratched.

In addition, Zytronic's 64-channel touch-screen controller assures optimum response for large format and widescreen panels.
