After the innovation of capacitive touchscreens, many users switched to this technology for their applications. Having some challenges in operation and to improving usability, an advanced version of capacitive touch sensors was introduced, named projected capacitive touch sensor technology. PCAP touch screens revolutionized smart touchscreen applications. As a result, today we have countless devices, including smartphones, tablets, human-machine interfaces, and many smart appliances which are using PCAP touch sensors.
PCAP has many benefits that make it an ideal choice for large segments of applications. Following are a few benefits:
Resistant to Contaminants and Vandalism
PCAP touch screens are designed with a highly durable glass surface that makes them robust against vandalism. The glass surface makes it resistant to scratches and abrasions. Moreover, the screen when sealed properly protects against the intrusion of dirt, dust, and other contaminants.
Highly Sensitive to Touch Commands
Among all the touch screen types, the entire range of capacitive touchscreens are said to offer an excellent level of sensitivity to touch commands. The touch sensor responds quickly, even to the light-pressure touch.
Optical Clarity
Evolving touchscreen technology has also focused on enhancing optical clarity. It is an important thing to consider while designing touchscreen devices particularly when sunlight readability is required. PCAP touch screens offer better light transmissibility since all its optical layers are bonded together with no air gap eliminating internal reflective surfaces. They allow for better transmission of light from the display they are affixed to.
Multi-Touch Capability
PCAP also offers multi-touch capability. Typically, up to 10 simultaneous touch points can be sensed by PCAP. This enables advanced gesture recognition such as pinch, zoom, and rotate functionality. Many of the other types of touch screens can only provide one or two touch capability which can be limiting in touch functionality.
Stylus, Light Gloves, or Bare Finger
PCAP touch screens support both bare finger and stylus operation. Stylus operation does require a special conductive type of stylus which is widely available. Lightly gloved hands such as nitrile, latex or vinyl gloves will also work well with PCAP sensors.
With all the above-listed benefits, undoubtedly, PCAP touch screens become great choice for a great number of applications. However, to fully leverage these advantages, it is important to choose the right manufacturer.
A D Metro is a reputable manufacturer of quality PCAP touchscreens, offered with a patented group controller and high-quality glass-on-glass sensor construction.
