Multi Touch Technology

MPCT™ mutual capacitive technology offers most of the durability advantages
of PCT™ projected capacitive technology, but with added multi touch capability.

About the technology

Zytronic’s patented MPCT™ touch technology is capable of detecting 40 or more touch events at once. And there’s no compromise on accuracy, even at ultra large sizes up to 85″. MPCT™ multi-touch sensors are capable of millisecond-fast response speeds and excellent touch-point resolution.


The MPCT™ multi-touch sensors are typically constructed from a laminated toughened glass substrate of up to 10mm thick, meaning they are durable enough to withstand most impacts and extreme environments. The sensors are unaffected by rain or liquid spillages and as they only react to finger, conductive stylus or gloved hand, “false” (accidental) touches are minimised.


Designed and manufactured at our in-house glass processing facilities, our dedicated and experienced engineers create bespoke products tailored to the exact requirements of our clients and their customers.
MPCT™ touch sensors are available in a near limitless choice of sizes, in glass of various thicknesses and types – for example, anti-reflective, mirrored and anti-microbial surfaces are available. Customers can also specify whether their touch screen is flat or curved and request special edge profiles, cut outs, holes and slots, as well as screen-printed logos and borders in a variety of colours.
Zytronic MPCT™ sensor technology is also available in a flexible, rollable film format, allowing for integration on to substrate for permanent and semi-permanent applications.


MPCT™ multi-touch technology will detect fingers, conductive stylus and even gloved hands, through glass thicknesses of 10mm or more. Yet, it ignores raindrops, leaves, dirt, ice, etc., making the touch sensors ideal for self-service and public use, in any environment.


With its unrivalled durability, MPCT™ provides 24/7 functionality in the most difficult of environment, minimising system downtime, reducing maintenance and maximising return on system investment. It is proven, dependable vandal-resistant and is practically immune to most types of physical, mechanical and chemical abuse.

How it works

A two layer matrix of microscopic conductive cells is laminated to the rear of the MPCT™ touch sensor and a small charge is applied to one layer, which in turn passes to the other. When a finger or conductive stylus approaches the surface of the MPCT™ sensor, a change in the charge is induced and detected in the nodes immediately beneath adjacent cells. The position of this change is then calculated by the touch controller, and its X-Y coordinate is output to the host Operating System.
Unlike conventional capacitive, acoustic and optical touch sensors the active component of MPCT™ is embedded behind the front substrate, ensuring protection, long life, and stability.
