Resistive Touch Technology Comparison ULTRA vs. Standard Resistive

This is a brief touch screen technology comparison between 5 wire standard resistive and 5 wire ULTRA resistive.

Criteria	Resistive	ULTRA
Touchscreen Surface	Polyester	Polyester + Glass
Input Method	Finger, Glove, Stylus	Finger, Glove, Stylus
Activation Force	Maximum 60 grams	Maximum 80 grams
Activation Accuracy	1.5% of the diagonal	1.5% of the diagonal
Touch Lifespan	60 million touches per point	250 million touches per point
Stylus/Pen Resistance	Susceptible to ITO cracking caused by pen	Less susceptible to ITO cracking caused by pen drags due to stiffer surface
Surface Hardness	3H	6.5 Mohs
Repeated Use Surface Wear	Wears through hardcoat, causing a milky appearance	Glass surface outlives lifespan of the sensor with no wear
Pillowing/Puffiness	Can occur at temperature, humidity and altitude extremes	Stiffer surface reduces chance of pillowing
Transmissivity	> 80%	> 80%
Environmental and Operational Envelope	-10°C to +55°C	Extended operating range due to stiffer surface giving pillowing resistance
Abrasion Resistance	Can withstand light scratches	Can survive deep scratches and gouges.
Moisture and Humidity Resistance	Moisture can permeate through polyester over time causing oxidation, shorts or false touches	Glass surface impervious to moisture
Chemical Resistance	Medium especially over time	Superior to all solvents that do not attack glass
Fire Resistance	None	Can withstand open flame for short periods and sparks
Altitude Resistance	10,000 feet operating	14,000 feet operating
Warranty	3 years	5 years
