What Challenges Are Posed by an Outdoor Environment?
Systems located outdoors without the protection of shelter are subjected to the rigors of weather, sunlight, and errant objects. As the most frontline component, PCAP touch solutions bear the brunt of scorching summers transitioning into subzero winters, UV damage, and the occasional vandal. In addition to weathering harsh conditions, AMT PCAP touch panels are built to deliver a superior user experience.
The Sun, a Relentless Adversary
For applications placed under direct sunlight, sunlight readability is crucial. The reflective rate for an air-bonded PCAP touch panel is approximately 12%. AMT provides a Low-Reflective optically bonded polarized PCAP touch solution that reduces reflective rate to an average of 1.5%. Surface treatments include clear glass with anti-reflective and anti-smudge coatings (standard) and anti-glare glass with anti-reflective and anti-smudge coatings. The high power lamp is simulating sunlight. The display is hard to see on the standard PCAP touch panel. On the AMT LR solution, display content is clearly readable.
Extended exposure to sunlight causes UV damage and material degradation such as yellowing and bubbling. AMT’s anti-UV design mitigates UV damage. AMT’s anti-UV panels have passed ASTM G154 Cycle 1 at 500 hours.
Protection from the Unexpected
You can never be sure what objects might strike your touch panel in an outdoor setting. Tree branches, shopping carts, and other objects can all impact the touch surface accidentally. Some systems may also require vandal-resistance. AMT provides cover lenses that meet IK10 specifications using thick glass, strengthen glass, or laminated glass. The IK10 impact test specifies an impact energy of 20 joules which is equivalent to a 5kg steel ball dropped from a height of 400mm. In addition, AMT technology ensures gloves can be used during operation even with a 10mm thick cover lens.
PenMount All-weather Operation
PenMount System Reference (SR) is a proprietary environmental calibration tool that stabilizes operation within a wider temperature and humidity range and when there is a rapid change in temperature. In addition, PenMount water handling prevents false touch signals in rain and offers basic touch functionality.
