Outdoor Touchscreen

MicroTouch Near Field Imaging is a touchscreen for applications exposed to direct sunlight that must be durable enough for outdoor use.


The screens incorporate a nonmetallic, Vikuiti solar-reflecting film to reflect infrared solar energy while still transmitting visible light. The film is laminated between the top glass and the sensor and reflects heat-producing infrared solar energy that can cause premature failure of touchscreens in outdoor kiosks and ticket booths.
