When touched, the capacitance on the electrodes changes, allowing the touch location to be detected.
PCAP touch screens can be used with laminated glass, making them ideal for applications that require enhanced durability and scratch resistance. The laminated glass also improves optical clarity, resulting in a clearer and more vibrant display.
One of the key advantages of PCAP technology is its multi-touch capability. PCAP screens support both single and multi-touch options, enabling users to perform gestures such as pinch-to-zoom and swipe. This makes PCAP screens highly intuitive and user-friendly.
PCAP touch foils are a popular PCAP technology that can be easily retrofitted onto existing displays or glass surfaces, making them a cost-effective solution for adding touch functionality to various applications. PCAP touch foils are commonly used in interactive touch tables, where users can interact with digital content in a collaborative and engaging manner.
Another PCAP technology worth mentioning is interactive projection foils, which can transform any non-touch surface into an interactive display. These foils can be applied to glass, acrylic, or other transparent materials, allowing users to interact with projected content. Interactive projection foils are commonly used in retail displays, exhibitions, and other interactive installations.
