Capacitive touchscreen from Zytronic 

innovative capacitive touchscreen technology development

What we offer

With our strategic and technological partner from England - Zytronic Displays Ltd. - we are able to offer you another advanced and extremely robust touch technology since the beginning of 2016. Optimized especially for the outdoor area and for industrial environments, we can now offer you touch-solutions as a capacitive touchscreen or as a complete system, in which projected capacitive touch sensors from Zytronic are used. With this technology, the actual display is offered separately from the transparent front (including touch functionality), which is why you can plan the touch regardless of the display selection.

PCAP technology

Our projected capacitive touchscreens (mostly called “PCT” = “Projected Capacitive Touch” or “PCAP”) are made up of two layers of thin copper wires in a diamond pattern. There is a transparent insulating layer between the two layers. This structure is now comparable to two capacitor plates, which are separated by a dielectric. With a controller, both layers of copper wire are now permanently exposed to tiny currents and the difference between signal input and signal output is measured. If a finger or an electrically conductive object comes close to the copper wire levels, the capacitor field is changed locally. This change is detected by the controller and spatially precisely assigned via an X-Y grid and translated into a desired touch event.

Due to the high sensitivity of the system, the sensor can be attached to the back of a glass pane and finger contact can even be detected through the glass surface (i.e. virtually projected). It is operated on a hardened, wear-resistant and scratch-resistant glass surface. In addition, this copper wire technology, in which the copper threads are laid out from the roll in special patterns, enables batch sizes from 1 piece and without any tool costs.

Due to the detection mechanism via field changes in the capacitor structure, operation can be carried out without pressure. Using Zytronic technology and the in-house development of the touch controller including firmware, operation can even be made possible with gloves. Because only the functional interaction between touch hardware and evaluation software unlocks all the possibilities that this technology offers. Special functions such as object detection by marking objects and the associated storage of special effects are also possible. Interference from unwanted touch events (e.g. from drops, oil, sand, insects, the heel of the hand or ice) can be easily excluded using the controller.

Furthermore, the detection of multiple touches (called multi-touch) is possible as well as the scaling of the system size with this technology up to 85 “. This enables common smartphone functions such as zooming by "pull apart" or even object recognition in industrial input systems, which are based on our capacitive touchscreen technology.

Technical realizations

The technical implementation of the copper wire PCAP technology as a capacitive touchscreen can now take place in several variants:

  • Copper wires glued into foils for self-lamination
  • Copper wires including protective film on the back of tempered glass
  • Glass film glass touch (copper wire foil glued between 2 glasses)

For all versions with glass surfaces, we offer additional glass processing such as rounded corners, chamfered edges or openings for mechanical controls. Tempered glasses for maximum resistance in thicknesses of 3-20mm are standard with us and can be upgraded via surface coatings or printing on the back of the glass.

Since only a correctly configured capacitive touchscreen enables high added value and high reliability in operation, we offer a special software tool for initial calibration for all touch solutions from Zytronic. This software tool not only allows you to correctly set minimum distances between sources of interference (display, RFID reader ...) and the capacitive touch, but also to freely adjust the sensitivity up to non-contact actuation (proximity sensor functionality). After this initial setup of the overall system, no recalibration over the entire service life is necessary compared to other technologies, since the extremely robust copper wire technology does not experience any changes due to mechanical or thermal influences.

The correct ground connection of all electronic elements, which are used in combination with our touch controller combinations, ensures reliability over the entire service life. Thanks to our know-how in dealing with input and operating systems of all kinds, many errors when setting up capacitive touchscreen systems can be avoided even with the integration idea.
