What is the Best Touch Technology for Rugged or Outdoor Environments?

Are you engaged in a touch display to be used in a rugged or outdoor environment? Have you been wondering which touch technology is the best for your display?


Planar's Director of Engineering believes any of the all glass sensors, such as Surface Acoustic Wave (SAW), projected and surface capacitive can work in rugged, outdoor applications, but no single touch can do it all. High ambient sunlight conditions pose interference problems with IR matrix and IR camera scan systems.


SAW and surface capacitive have varying resistance to rain, dust, snow and flying insects. Glass-on-glass resistive has good immunity to the outdoor environment, but requires additional optical enhancements to compensate for unwanted ambient, outdoor, light reflections, which detract from the display's contrast.


Regardless of your project, the option to choose from multiple touch technologies will make the touch decision much easier.
