Resistive vs PCAP Touchscreens
The two most common touch technologies are resistive and projective capacitive (PCAP). Projective capacitive touch is quickly becoming to superior solution due to its rapid evolution in recent years. PCAP Touch is becoming the preferred touch technology especially for industries exposed to harsh environments. But why? Learn the differences between resistive vs PCAP touchscreens.
Resistive uses a film surface that requires more pressure to activate the touch, which can disrupt the accuracy of the touch point. Film is also less transmissive, yellows when exposed to sunlight, and scratches easily. For these reasons, resistive is not the ideal touch solution for longevity. Resistive is also limited when it comes to touch points, only supporting single touch.
Projective capacitive touch uses a top layer of glass. This allows for high quality screen contrast, optical clarity, and overall durability. The glass component also offers the option for more customization, allowing for different cover lens materials (soda lime, chemically strengthened, etc.). Another advantage of PCAP its multi-point inputs or 'multi-touch' capabilities. When PCAP is touched with a finger, an electrical charge is produced that allows the display to detect the touch point. This helps prevent false touches that could be triggered by conductive liquids, like saltwater or oil.
