Resistive and Capacitive Touch Display Solutions

TFT touch panels combine with ARM-based system-on-modules to create solutions

Capacitive, and resistive, touch screens are often used by us, and by our customers to create embedded systems with compelling touch and gesture based GUIs (graphical user interfaces).

We strive to support the broadest possibly range of touch screens and GUI technologies – such as Qt – and a high proportion of our projects include touchscreen-based HMIs. We can recommend and supply a display, but also support almost any 3rd party TFT, whether resistive or capacitive touch, directly connected or LVDS.

Touch screen based user interfaces are foremost in the solutions we provide in industrial, medical, transportation and enterprise applications. A tiny, production ready ARM9 or ARM Cortex-A8 / A9 based module is often the ideal engine for this type of project.

If you are thinking of creating a system with a touch-screen, but don’t know where to start, you can access our expertise in a variety of ways. Fill in our touch-screen project definition form, which signposts the key questions which will define your solution. Contact one of our engineering support team who will be happy to discuss your project in technical detail. Or read on, to discover how for low to medium volume projects, a modular, production-ready solution can get you to market in a matter of weeks.

We ensure that our extensive range of modules can work with the resistive or capacitive touch screen that best suits your application. This starts with the development system, such as the Mainboard-7 – which is common to our TRITON-TX range of modules – which can be supplied with a range of capacitive and resistive models from EDT with a unified interface, with support out of the box.

In production, while some customer projects use the EDT displays supplied with the Mainboard-7, many go on to choose displays from other vendors, whether capacitive, resistive or using other touch technologies, whether interfaced directly, via LVDS or HDMI/DVI, and our goal is to make it easy to use the display of your choice. The board support packages for Linux and Windows CE / Compact 7 / Compact 2013 which are provided for the various modules  all support the full range of EDT resistive and capacitive TFT panels – and are also easily configurable to support other manufacturers’ displays.

Some modules have an inbuilt resistive touch controller, for others this is on the baseboard. All modules support capacitive touch via an I2C interface.
