Capacitive multi-touch screens - precision and versatility
Capacitive multi-touch screens, also known as CTP (capacitive touch panels), offer a modern, intuitive user experience that is characterized by high precision and responsiveness. They react to electrical changes caused by touching them with a finger, making them easy to operate even with several fingers at the same time (multi-touch). This technology is used in many industrial and medical applications where complex inputs and user interactions are required.

Sensor technology
Functionality of PCAP multi-touch sensors
Capacitive technology
PCAP touchscreens use a thin layer of conductive material such as indium tin oxide (ITO). This layer forms an electric field that changes when touched. This change is recognized and interpreted by a touch controller.
Sensorgrid
The capacitive sensor grid consists of a matrix of electrodes arranged in a grid structure. Each electrode generates an electric field that changes when touched. The exact position and number of contact points are determined by analyzing the capacitance changes in this matrix.
Signal processing
The signals from the electrodes are forwarded to a touch controller, which processes the data and converts it into coordinates that are interpreted by the device's operating system and software.
Touch sensors for single touch
The touch sensors in resistive single-touch displays are at the heart of this technology. They consist of two transparent, conductive layers that are separated by small spacers. When touched, the upper layer is pressed onto the lower layer, which generates a voltage at the point of contact. This change is detected by the electronics and recognized as a precise contact point. This simple but effective mode of operation makes resistive touch sensors extremely reliable and versatile, even in difficult environments.
