PCAP Touchscreens & Infrared Touchscreens-The DifferencesJoanna Kay
As we have recently begun to concentrate on the supply of PCAP touchscreens as opposed to Infrared touchscreens, one of the most frequent questions we answer is, “what is the difference”? To fully understand the differences, we need to look first at how each technology works.
Put simply, Projected Capacative touch (or PCAP for short) is the newest technology available and is the same as you see on a smartphone or tablet. Using your finger or a stylus to touch the screen signals a change in the system’s electromagnetic field and capacitance. These changes are converted to grid locations applied to the screen and that allows the system to determine where your touch is. Basically, everything happens beneath the surface you touch.
Infrared touchscreens are now an old technology and almost the complete opposite of PCAP. Infrared uses an overlay of infrared beams that criss-cross the screen and register a touch point where you break the beams. With this technology, everything happens on or just above the surface you touch.
So far, so good but what you will be really interested in is the advantages the PCAP technology can provide you with.
What are the advantages of PCAP touch technology?
PCAP touchscreens have greater sensitivity and accuracy providing up to 60 touch points; that’s 50% more than the older infrared screens with only 40 touch points. This can be particularly important if you are using the touchscreen in a group or educational environment as it allows a greater number of people to use the screen at the same time.
Because all the technology is below the surface of a PCAP touchscreen, you can have an all flush glass surface; infrared screens require a bezel in order to overlay the beams. This means your screens are much easier to keep clean.
Without the need for a bezel, PCAP touch technology can be incorporated into much thinner and more durable displays meaning your screens will last longer.
PCAP touchscreens will only detect a finger or a stylus meaning that solid objects can be placed on the surface of the screen without interfering with the touch capability. This is great if you are using your touchscreens as, for example, table tops.
As the touch function on a PCAP screen operates below the surface, they are impervious to light interference therefore giving them the ability to work in any setting.
At Screenco, we have recently launched a brand new range of PCAP touchscreens, both indoor and outdoor, in sizes from 22” to 84”. Call us on 0161 73 81 999 and one of our team will be happy to discuss how you can benefit from PCAP touchscreen technology.
