Touchscreen Technologie Vergleich ULTRA vs Resistive
This is a brief touch screen technology comparison between 5 wire standard resistive and 5 wire ULTRA resistive.
| ULTRA | Resistive | |
|---|---|---|
| Surface | Glass | Polyester |
| Input Method | Finger, Glove, Stylus | Finger, Glove, Stylus |
| Activation Force | Maximum 80 grams | Maximum 60 grams |
| Activation Accuracy | 1.0% of the diagonal | 1.0% of the diagonal |
| Touch Lifespan | 250 million touches per point | 60 million touches per point |
| Stylus/Pen Resistance | Less susceptible to ITO cracking caused by pen drags due to stiffer surface | Susceptible to ITO cracking caused by pen |
| Surface Hardness | 6.5 Mohs | 3H |
| Repeated Use Surface Wear | Glass surface outlives lifespan of the sensor with no wear | Wears through hardcoat, causing a milky appearance |
| Pillowing/Puffiness | Stiffer surface reduces chance of pillowing | Can occur at temperature, humidity and altitude extremes |
| Transmissivity | > 80% | > 80% |
| Environmental and Operational Envelope | Extended operating range due to stiffer surface giving pillowing resistance | -10°C to +55°C |
| Abrasion Resistance | Can survive deep scratches and gouges | Can withstand light scratches |
| Moisture and Humidity Resistance | Glass surface impervious to moisture | Moisture can permeate through polyester over time causing oxidation, shorts or false touches |
| Chemical Resistance | Superior to all solvents that do not attack glass | Medium especially over time |
| Fire Resistance | Can withstand open flame for short periods and sparks | None |
| Altitude Resistance | 14,000 feet operating | 10,000 feet operating |
| Warranty | 5 years | 3 years |
