WHAT ARE CAPACITIVE TOUCH SCREENS?
Capacitive touch screens are perfect for customers looking for an alternative to resistive touch screens. Nelson-Millers capacitive touch screens use electrical impulses found in the human body to detect a specific location where the user has touched the display. This allows capacitive touch screens to be controlled by the lightest of touches by usually a fingertip. It is also why styluses or gloved hands typically do not respond well with capacitive touch screens, because they do not generate enough electrical impulses.
Capacitive touch screens come in two different forms: surface capacitive and projected capacitive touch screens . While both utilize capacitive technology, they are used in different applications. Surface capacitive touch screens are often used in relatively large panels and are commonly found in vending machines and ATMs. Projected capacitive touch screens, on the other hand, are used for smaller screen sizes, including smart phones and tablets.
The transparent protective coating and innovative capacitive touch screen overlay make capacitive touch screens resistant to scratches and abrasion, while leaving the responsiveness of the touch screen unaffected. The performance of all Nelson-Miller touch screens are unaffected by everyday use, including dust, condensation, minor liquid spills, contaminants, or cleaning solutions.
Capacitive touch screens are best when multi touch screens are desired. The display can recognize more than one point of contact. Without multi-touch capabilities, gestures such as pinching and spreading the screen to zoom in and zoom out are not possible.
