Projected Capacitive Touch Screen Design

Projected Capacitive (PCAP) touchscreens detect touch via a grid of sensor wires that create an electrostatic field. A finger or stylus disrupts this field, which is measured as a change in capacitance. This technology supports accurate multi-touch input and can be placed behind a protective glass panel. This increases durability and robustness, making it ideal for demanding environments from industrial to public use.

Industrial HMI

Industrial HMI

PCAP displays are ideal for Human Machine Interfaces in factory automation and heavy machinery. They offer reliable operation in harsh environments with dust, moisture and vibration, and can often be operated with gloves for added safety and ease of use.

Medical Equipment

In the medical sector, these screens are used in patient monitors and diagnostic equipment. The seamless glass surfaces are easy to clean and disinfect, which is essential for hygienic environments. The technology supports precise input for critical medical tasks.

Outdoor Kiosks

For public kiosks and ticket machines, PCAP displays offer the durability and weather resistance needed. They function through thick, vandal-resistant glass and withstand rain and extreme temperatures, making them ideally suited for unattended outdoor use.

Transportation and Vehicles

These touchscreens are integrated into automotive infotainment systems, public transport displays and maritime navigation. Here, their robustness, reliability and good readability in changing light conditions are crucial for safety and functionality.

Glove control

The technology supports operation with various types and thicknesses of gloves. Sensitivity can be matched to materials such as latex, cotton or leather, which is essential for industrial and medical applications where users frequently wear gloves.

Water resistance

Advanced PCAP controllers offer excellent water rejection and detection. The display continues to function when exposed to liquids, drops or splashes and can ignore false touches from water, which is critical for outdoor use and medical devices.

EMC Resistance

PCAP solutions are designed with high resistance to electromagnetic interference (EMI). This ensures stable and reliable operation in environments with a lot of electronic 'noise,' such as factories, hospitals and vehicles with a lot of equipment.

Operation by Thick Glass

The sensors can detect touch through a thick protective layer of glass, up to 10 mm. This makes the screens extremely vandal-resistant and durable, ideal for unattended public kiosks and heavy industrial applications.

Summary

Projected Capacitive (PCAP) touchscreens detect touch via a grid of sensor wires that create an electrostatic field. A finger or stylus disrupts this field, which is measured as a change in capacitance. This technology supports accurate multi-touch input and can be placed behind a protective glass panel. This increases durability and robustness, making it ideal for demanding environments from industrial to public use.
