Tougher touch screen takes the knocks: News from Danielson (UK)

A new touch screen is billed as ideal for use in bank cash points, public kiosks or other applications where the interface has to withstand excessive use and possible surface damage, both accidental and deliberate. The new touch screen incorporates a specially developed outer glass layer, that is thin enough to enable the underlying electronics to function effectively, but of sufficient thickness to prevent damage to the touch screen mechanism. When located in a suitable housing, the glass layer enables the new touch screen to be used in applications where dirt, moisture, aggressive chemicals, gasses or extremes of temperature are encountered.

In addition, the outer layer will withstand physical surface damage and will continue to operate even if it is deeply scratched with a sharp object or glass cutter.

The new Danielson touch screen uses conventional, five-wire resistive technology, with a single dynamic polyester layer being coated with indium tin oxide (ITO) and separated from a ITO coated glass support panel by microscopic dielectric spacer dots.

Operation can be gloved hands, a stylus or similar instrument, with the operating force normally being less than 100g.

The new technology extends Danielson's existing range of touch screens still further.

In addition, the company believes that its new touch screen will enable product designers to use resistive technology for applications where previously only more expensive capacitive or surface acoustic wave systems would have been considered.
