I need to use the most dependable touch screen for our new product, which one? – Gerry, Mooselookmequintic, ME

Hey Gerry, (BTW, is that really your town?), I like questions where I don’t have to give a wishy-washy answer. First, for the neophytes amongst you, there are five commercially viable touch technologies, from a list longer than the number of letters in your city….they are, Resistive (four types), Surface Capacitive (two types), Infrared, Surface […]

Which Touch International touch screens are able to withstand extreme temperatures and are suitable for the automotive industry? – Vivek

Dear Vivek, Touch Guy knows that making parts for fighter jets is a whole lot easier than meeting the specifications for the automotive market. There are a few automobile tests that we use to evaluate the effects of temperature extremes on LCDs. The best assessment is the Phoenix test where a car is left in […]

Hello Touch Guy! My name is Jeffery. I have a new product that I would like to finish the prototype for, but…I cannot find a flexible, yet durable touch film (no glass) I can use. The size needs to be approximately 12″ x 12″ (+/- 1 or 2″) but I am willing to look at other options. I am talking to the TV show, Shark Tank, and counting on a few other companies to bring this product to market. The problem I am facing is manufacturing’s willingness to deal with me. I’m not asking for something for free and am willing to pay for a sample unit, but the supplier must be able to supply 1,000 units at a time. Do you have any suggestions for companies that can provide a flexible touch film? – Jeffrey Gelman, FootMouse TouchPad Team

Hey Jeffery….relax, Touch Guy is here to help. I hear this story a lot, unfortunately most often from my American competitors. And, a Google search of “touch screens” lists the company most likely to help you–Touch International-on page 12, even though they are the second largest US manufacturer of touch products. (Hear that Bing?) But […]

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 […]
