Capacitive touch panels register touch by reacting to the minor electrical charges that run through our bodies. A standard design consists of two glass layers coated with a conductive agent and a built-in flexible circuit assembly known as a COF (chip on flex). Touching the screen causes a change in the screen surface’s capacitance value, registering the exact point where the screen was touched.
This type of touch screen has high contrast, accurate input, and supports multi-touch actions. These intuitive features, paired with exceptional durability, make capacitive touch screens ideal for consumer and industrial products.

Advanced PCAP Touchscreen Technology for Mobile Devices
PCAP (projected capacitance) technology is even further advanced at sensing touch and offers a water-clear display. These capacitive touch screens register touch in up to twelve places simultaneously to allow scrolling, flicking, and pinching to zoom in on text or images.
Smartphone manufacturers have solely adopted PCAP touch screens because of their extreme accuracy and ability to work even after the screen has been scratched or cracked.
Because PCAP touch screens rely on using the minor electrical charges that run through our bodies, they have historically only worked when touched with a bare finger or a conductive item. However, new developments in technology has given manufacturers the ability to make PCAP touchscreens that can be used with gloves and nonconductive implements.
Capacitive Touch Screen Benefits: Flexibility Meets Durability
Custom capacitive touch screens are typically more expensive but deliver durability and accuracy that make them desirable for smartphones, tablets and other mobile devices. Advantages of PCAP touch screens include:
- Greater accuracy and faster response
- Requires less pressure to register touch than resistive screens
- Can support up to 12 multi-touch interfaces
- Continues to work even when the screen is cracked, pierced or scratched
- Water resistant technology available
- Higher contrast and exceptional image quality
- Screens should not become unresponsive over time
