Projected Capacitive (PCT) Touch Screen

Works through Glass!! Ideal for Railway Outdoor Kiosk - can use additional glass in front to avoid breakage of Touch Screen.

Traditional touchscreen sensing technologies, such as capacitive, resistive and surface acoustic wave are surface-active and therefore, more susceptible to surface variance effects during the screen's lifetime. Capacitive sensor arrays are often subject to drift, which means that regular recalibration is required and consequently, maintenance is more expensive. Resistive touch technology is more prone to damage caused by sharp pointing devices such as a pen or the corner of a credit card. PCT eliminates all of these problems by providing a robust, reliable and calibration-free, non-surface active glass fronted touch solution. 
PCT is based on the principle of embedding an array of micro-fine sensing wires within a multi-layer laminated screen behind a protective front surface, ensuring that the sensing medium is well-protected from accidental and malicious damage. This technology is extremely robust and reliable, offers one of the industry's highest light transmission characteristics and can be operated with a gloved or ungloved hand. 
PCT has unlimited touch life, is drift-free, and so requires minimal maintenance. PCT is currently employed in a wide range of touchscreen-based applications that require high-end solutions, such as public access information kiosks, jukeboxes, ATMs, gaming machines and medical and industrial applications.
