Projected Capacitance Touchscreens: What You Should Know

Advantages of Projected Capacitive Touchscreens

Projected capacitive touchscreens are often preferred over other types of touchscreens because of their superior sensitivity. All capacitive touchscreens are sensitive, but projected capacitive touchscreens offer the highest level of sensitivity. Just hovering your finger over the display interface is often enough to trigger a touch command.

Another advantage of projected capacitive touchscreens is their native support for multi-touch commands. Multi-touch, of course, refers to touch commands involving two or more simultaneous points of contact. Pinching the display interface is a common example of multi-touch. It requires two points of contact, thus it's considered a multi-touch command. Not all touchscreens support multi-touch commands. Projected capacitive touchscreens, however, do support them.

Normally, capacitive touchscreens won't register touch commands performed while wearing gloves. This is because they rely on capacitance to detect touch commands. If you wear gloves, your finger won't distort the electrostatic field, meaning the device won't register your command. With that said, you can typically wear thin gloves, such as surgical gloves, when using a projected capacitive touchscreen.

Projected touchscreens also have a long lifespan. They don't contain any mechanical or otherwise moving parts. As a result, projected touchscreens don't suffer from age-related wear and tear like other types of touchscreens. These are just a few of the many advantages of projected capacitance touchscreens.
