PCAP Technology
Projective Capacitive touchscreen (P-CAP, Pro-Cap or PCAP touch screens) sensors function by maintaining a standing electrical charge across the sensor that extends through a contact surface, where changes in the electrical charge caused by the proximity of other capacitive bodies (such as touch stylus, fingers etc.) can be detected by a
Due to the glass surface, the PCAP touch screens are particularly scratch-resistant and can be cleaned with all cleaning agents - an important advantage in hygienically sensitive areas.
With special protective glasses, the touch screens are vandal-proof and can be used in public areas. However, the number of touch points may vary depending on the strength of the protective glass used. We can offer the touchscreens also as a unit with a protective glass and / or a TFT display.
This PCAP touchscreen technology is generally now used as the preferred method of user interface for modern tablets and smart phones because the touch sensor is on the rear it allows for a true flat edge to edge cover glass given this up to date feel for the touchscreen. We can produce Capacitive touchscreens from as small as 1.77” diagonal to 86”
We represent various projective capacitive touchscreen suppliers including Zytronic, DMC and our own bespoke range of
We now offer our own Hover Touch technology as well as Zytronic who held their webinar earlier on in the year

The difference between Capacitive and Resistive touch screen
What is the difference between Capacitive touch screens and Resisitve touch screens? Resistive technology has been somewhat overtaken by capacitive technology when it comes to touchscreen monitors and devices. To the average eye, both resistive and capacitive touch screens perform the same function, however there are some notable differences between the two technologies.
Capacitive touch screen technology is unrivalled, with numerous benefits including heightened touch sensitivity, a brighter and sharper display and multi-touch support whilst fine cracks and scratches do not hinder the overall performance.
rely on the mechanical pressure made by a finger or stylus, whereas capacitive touch screens rely on the electrical impulses of the human body which cause a change in the electrical field of the screen. Essentially, resistive screens rely on pressure and capacitive screens use electrodes to sense conductive properties.
