Projected Capacitive Touch Technology (PCAP) is an excellent solution for various industrial-grade applications, including process control terminals, medical displays, and agricultural vehicle telemetry systems. Its performance remains unaffected by scratches, dirt, or dust on the screen, ensuring reliable touch functionality in rugged environments. PCAP technology can be operated by users wearing heavy gloves and can be sealed to achieve high IP ratings, making it well-suited for challenging conditions or outdoor deployments where durability and precision are critical.

What is Projected Capacitive Touch?

Projected Capacitive Touch Technology (PCAP) is a touch-sensing technology that uses a grid of conductive layers to detect touch input. It works by projecting an electrostatic field through the screen, and when a conductive object, such as a finger, comes into contact with the surface, the system detects the change in the electrical field and pinpoints the touch location. PCAP technology is highly responsive, supports multi-touch gestures, and is commonly used in modern smartphones, tablets, and industrial applications due to its durability and precision.

Projected Capacitive touch technology allows touch input to be sensed directly or through a protective outer layer. The touchscreen consists of a standard 3mm glass layer but can detect touch through an additional outer layer, including vandal-resistant glass up to 10mm thick. Depending on the chosen outer layer, the system can withstand impact, scratches, vandalism, extreme temperatures, rain, snow, ice, and harsh cleaning fluids, making it ideal for demanding outdoor applications.

Benefits of a Projected Capacitive Touch Screen

Projected Capacitive Touch Screens offer several key advantages, including a true flat front surface without the need for a bezel, which enhances both the aesthetics and durability of the display. They provide exceptional input flexibility, functioning seamlessly with gloves and maintaining reliable touch performance even if the glass is scratched or broken, ensuring long-term usability in demanding environments.

Applications of a Projected Capacitive Touch Screen

These versatile touch screens are ideal for a variety of applications, including outdoor kiosks, ticketing machines, ATMs, and pay-at-the-pump gas stations. Additionally, they are well-suited for through-glass, under-counter, and bartop installations, making them an excellent choice for environments where durability and reliable touch functionality are essential.
