PCAP Touchscreens: The Current Market Standard

PCAP (Projected Capacitive) is the leading touchscreen technology, familiar from smartphones and tablets. Unlike resistive screens, these use the electrical properties of the human body. A wafer-thin conductive grid on the back of the glass panel detects the change in the electric field when a finger approaches. This technology enables a smooth, durable, and scratch-resistant glass surface, offers superior image quality, and supports advanced multi-touch gestures for an intuitive user experience.

Consumer Electronics

Consumer Electronics

PCAP technology dominates the consumer electronics market and is the standard in virtually all modern smartphones and tablets. The reasons for this are its excellent multi-touch capabilities, high optical clarity, and durable, scratch-resistant glass surface. Intuitive operation with swipe and pinch gestures has become essential to the user experience on these everyday devices.

Industrial control (HMI)

In industrial environments, PCAP screens are used for Human-Machine Interfaces (HMIs) and control panels. The robust, sealed glass surface is resistant to dust, dirt, and liquids, which is crucial in factories. The technology can be adapted for operation with gloves, increasing safety and efficiency for operators.

Kiosks and POS systems

Self-service kiosks, ticket machines, and point-of-sale systems frequently utilize PCAP touchscreens. The durability and vandal resistance of tempered glass are ideal for public spaces. The smooth surface is also easy to clean, ensuring hygiene in high-traffic environments such as stores and public transportation.

Medical Equipment

Hygiene is of the utmost importance in the medical sector. PCAP screens have a seamless glass surface that can be easily disinfected. In addition, they can be calibrated for use with medical gloves. This makes them ideal for control panels on diagnostic equipment, monitors, and other medical instruments.

Precise Multi-touch

PCAP technology excels at detecting multiple touch points simultaneously with high precision. This enables intuitive gestures such as zooming in and out, rotating, and swiping, which significantly improves the user experience. Modern systems typically support 10 or more simultaneous touches, which is essential for complex software and interactive collaboration tools.

High Optical Quality

Because the sensors are located on the back of the glass, there is no additional layer to interfere with the image. This results in excellent clarity, high contrast, and vivid colors. The glass surface offers superior optical transparency compared to older technologies such as resistive screens, which often produced a dull and less clear image.

Durable and Scratch Resistant

The surface of a PCAP screen is a glass plate, which is naturally very durable and scratch-resistant. Unlike the soft plastic layers of resistive screens, it is resistant to wear and tear from frequent use. This guarantees a long service life and a consistently high-quality appearance, even in demanding public or industrial environments.

Resistant to Moisture and Dirt

The seamless, non-porous glass surface of PCAP screens prevents liquids, dust, and other dirt from penetrating the internal electronics. This makes the screens easy to clean and highly suitable for use in environments where hygiene is important or where exposure to moisture and dirt is unavoidable, such as in industry or public spaces.

A wafer-thin conductive grid on the back of the glass panel detects the change in the electric field when a finger approaches.
