So Tyler, I guess you know water can be a lot of trouble for touch screens. The most vulnerable is SAW which stops dead in its tracks, to the least vulnerable, resistive touch. Resistive can be sealed so that water does not get in between the PET and glass layers which allows for better performance … Continue reading »

Is projected capacitive technology reliable when used outdoors in a marine environment where it will be exposed to rain, saltwater spray, bright sunlight, etc?
What are the likely points of failure?
- Charlie, Marblehead, Massachusetts
Hey Charlie: This is a most appropriate question for national sock burning day because, as is the case with all good sailors, Touch Guy barbequed his socks and pledged to go shoe-to-skin all the way to the last blustery days of Fall. Ah, but back to your question…Until recently, resistive touch was the only technology … Continue reading »

What adhesives do you recommend for bonding the touch screen to the LCD?
– Scott
Dear Scott: Touch Guy could simply say to use any VHB adhesive (VHB stands for very high bond), most commonly 3M 4956 mm, but it is not his style to be anything less than verbose. Touch Guy is usually not negative either, but he needs to be this time. There are two big no-no’s… neoprene … Continue reading »

It was with great excitement that I received my projective capacitive multi-touch kit from Touch International. My guidelines for our vendor were to find a touchscreen with multi-touch support and support for security glass. I’ve seen that there is no driver for this touch screen to support multi-touch. And on the other hand we tried to put a glass layer in front of the touch panel and it didn’t work. Another problem we are facing is that if the touch-panel comes near the lcd-panel the touch coordinates are wrong. What gives?
– Daniel Amesberger
Well, TouchGuy hangs his head in shame for letting you down. While the real world performance is fantastic, It turns out that this new-fangled projective capacitive (p-cap) touch is not quite so plug-and-play as the plain-old-resistive-touch. All touch technologies have their idiosyncrasy—resistive touch needs to be calibrated to the display, IR requires that the beams … Continue reading »
