The new highly transparent, high-resolution, high-reliability touchscreens from Touch International use infrared (IR) touch technology that provide a stable, maintenance- and calibration-free solution for point-of-sale (POS) and industrial process control display applications.

"Infrared has always been a very good touch technology; however, there were issues in the earlier versions with dead space or false touches when dust accumulated or objects landed on the IR transmissive bezel," said CTO Gary Barrett. "Today's firmware, advances in materials and science, and automated gain controls have obviated the problems to such an extent that IBM has adopted IR as its technology of choice in many of its POS products."

Since there are no films or conductive layers, standard transparency of the IRTouch touch screens is over 92 percent (with 100 percent possible). Sealed to the IP65 standard, the devices operate over the -41C to 70C temperature range. They are resilient and can operate in conditions from severe weather to factory environments where water, acid, oil, dust, dirt, moisture and EMI can be a problem.

Touch International said its new products employ innovative optical and mechanical designs that provide excellent performance in any type of ambient light conditions. They can be operated by any objectfinger, gloved hand or stylusand require no pressure on the touch screen surface itself. Response time range is from 10ms to 35 ms.

OEM pricing for standard IRTouch touch screens is $128 for the 12.1-inch and $149 for the 15.1-inch models. They are also available in smaller sizes (6.4-inch, 8.4-inch and 10.4-inch), larger sizes (30-inch to 100-inch) and custom sizes.
