Zytronic offers innovative Capacitive Touch Sensors using patented Projected Capacitive Technology (PCT). Taking advantage of the ultra large form factor capability of PCT, it is possible to design large size outdoor LCD Touchscreen Display System. With an all-glass front, PCT can be readily sealed and is already proven in outdoor applications to house the touch displays ensuring reliable performance in extremes of weather.

Capacitive Touch Sensors used in Outdoor LCD Touchscreen Display SystemZytronic Capacitive Touch Sensors and Touchscreen Displays can predominantly be used in an open air environment and are able to operate in all weather conditions, when coated in dust and dirt, and to resist vandalism. These are all attributes exhibited by PCT, the patented projected capacitive touch sensing mechanism at the heart of Zytronic’s touch sensor products. It is made up of a matrix of micro-fine capacitors, embedded within a tough laminated glass substrate which if required can then be placed behind a thick glass or polycarbonate protective overlay to provide unrivalled levels of protection for the touch display from all forms of physical damage, and high levels of durability and rendering the screen virtually impervious to the type of wear and tear that would cripple the longterm operation of alternative touch sensing technologies, such as resistive or surface capacitive screens. This greatly increases the touchscreen’s operational lifespan when compared to those based on traditional front-surface sensing technologies or even conventional projected capacitive screens, as it is unaffected by scratches, impact, vibration, humidity, heat or cold.

Furthermore, unlike resistive or surface capacitive touch screens, PCT touchscreens are not prone to sensor drift over time, negating the need to carry out costly recalibration or maintenance which can impact greatly on the true running cost of a kiosk.

PCT Capacitive Touch Sensors can be integrated into displays without the bezel structure around the active area that is needed with infrared (IR) and surface acoustic wave (SAW) based touchscreens. This allows for flat fronted designs to be created which are both practical and attractive. As an additional benefit, with its active sensing elements embedded on the rear side of a screen, PCT does not require time consuming and costly sensor recalibration maintenance to be carried out.
