PCAP (projected capacitive touch) and resistive touchscreens are two different technologies used in touchscreens.
PCAP technology uses a layer of glass with a conductive coating that stores an electrical charge. When a user touches the screen, the electrical charge is disrupted and the touch position is detected. This type of touchscreen is known for being highly responsive, durable, and suitable for multi-touch gestures.
Resistive technology, on the other hand, uses two layers of flexible material with a conductive coating, separated by tiny insulating dots. When pressure is applied to the screen, the two layers come in contact, causing the dots to connect and create an electrical signal that can be detected. This type of touchscreen is known for being softer to the touch and less expensive than other technologies.
In summary, the main differences between PCAP and resistive touchscreen technology are the materials used, the way touch is detected, and the level of responsiveness and durability of the screen.
