Touchscreen
Introduction to products with touch screen
Nearly all of our Series X products with touch screen uses Projected Capacitive Touch screen (PCTS), widely used with
great success on mobile phones and typical pad devices. PCTS can be equally effective also for marine applications.
One of the advantages of PCTS is that it has features seen in both resistive and surface capacitive touch screen
technologies.
Multitouch is defined as the ability to recognize two or more simultaneous touch points. Using projected capacitive
technology lets us create a more intuitive form of human-device interaction. Touch interface gestures, supported by
projected capacitive sensors, can simplify the interface and provide an intuitive user experience that goes beyond the
typical "button replacement" found in most simple touch interfaces.
Please review the appropriate Product Data Sheet (in this manual) to determine if PCTS are supported.
The technical benefits of PCT are:
- Very good optical performance (same as surface capacitive)
- Environmentally strong, the touch sensor is inside the product (better than both surface capacitive and resistive)
- Supports Multitouch (Newer Operating System (OS) required/dependent, see next page for info, section " *Note ")
- Strong against rain / drip
- Excellent readability - light transmission of up to 91% through a standard sensor
- Stability - no drift, therefore no recalibration is required
- Pointing device - works with gloved and ungloved finger
- Resistance to contamination - by harsh cleaning fluids and other noxious substances
- Communicates via USB to external computer or internally
