Capacitive touch screens

Capacitive touchscreens (PCAP – Projected Capacitive Touch) are a modern technology that has gained popularity in HMI (Human-Machine Interface) systems, multimedia devices, and points of sale. Unlike traditional resistive screens, PCAP responds to changes in the electrostatic field caused by a finger or conductive stylus touch, allowing precise operation and multi-touch features, such as zooming, panning, or rotating elements on the screen.

Definition of PCAP technology

Capacitive technology is based on projecting an electric field in a thin layer of screen glass. Touching the screen with a finger disturbs the local electrostatic field, allowing the control system to determine the exact coordinates of the touch point. Due to this principle, PCAP screens offer high sensitivity and accuracy even with minimal pressure, which distinguishes them from resistive screens that require physical pressure on conductive layers.

Differences compared to resistive screens

• Touch detection method: PCAP detects touch through electrical conductivity, while resistive screens operate based on the pressure of two conductive layers.
• Multi-touch and gestures: Capacitive screens allow multiple touch points simultaneously, enabling gestures like pinch, swipe, or rotate. Standard resistive screens typically offer only single-point or limited two-point functionality.
• Aesthetics and clarity: PCAP allows the use of thin glass with high transparency and anti-reflective coatings, enhancing user comfort and the visual appeal of devices.
• Environmental sensitivity: Capacitive screens are less resistant to moisture and dirt compared to resistive ones but gain in gesture handling and interactivity.

Popularity and role in modern HMI systems

Capacitive screens have become the standard in interactive control panels, self-service kiosks, multimedia devices, and POS terminals. Their precision, responsiveness, and sleek appearance make them indispensable in environments where high aesthetics, user comfort, and multi-touch gesture support are important. In HMI systems, PCAP enables faster operator interaction with machines, intuitive process control, and efficient use of graphical interfaces.
