Multi Touch Technology

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

About the technology

Multi-touch screens have become increasingly popular over the years as the desire to add more functionality to user interfaces has increased, moving from simple single-touch interactions to multi-touch interactions such as pinch to zoom and increasingly complex gestures. Added to this is the trend towards collaborative applications, larger touchscreens and multi-user touchscreens, and the importance of multi-touch capabilities becomes clear.

Zytronic’s patented MPCT™ technology is capable of detecting 40 or more touch events at once. With MPCT™, there’s no compromise on accuracy, even at ultra-large sizes up to 85″; our multi-touch sensors are capable of millisecond-fast response speeds and excellent touch-point resolution, meaning that even on large touchscreen tables with four or more simultaneous users, our multi-user touchscreens can easily handle the workload.

The Benefits

High-impact resistance

High-impact resistance

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 touches, meaning that “false” (accidental) touches are minimised.

When specified, our in-house processed, thermally toughened glass is up to 6x stronger than un-tempered material, making it ideal for public and unattended self-service use. Our touchscreens are also proven resistant to and unaffected by scratches, scuffs, or even intentional vandalism.

Customisation options

Customisation options

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, from smaller displays to large multi-user touchscreens.

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 onto a substrate for permanent and semi-permanent applications.

With over 20 years of expertise in our sector, we can advise your team and support your project throughout the design process.



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, including multi-user touchscreens.

Our multi-touch screens are available in almost any size and shape, including curved and round touchscreens while remaining lightning-fast and sensitive responses even when multiple users are interacting simultaneously.



With its unrivalled durability, MPCT™ provides 24/7 functionality in the most difficult of environments, 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. Performance is unaffected by liquid spillages or dirt, making them ideal for hospitality and leisure.

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.
