What Does Capacitive Touch Screen Mean?

A capacitive touch screen is a device display screen that relies on finger pressure for interaction. Capacitive touch screen devices are typically handheld, and connect to networks or computers via an architecture that supports various components, including satellite navigation devices, personal digital assistants and mobile phones.

A capacitive touch screen is activated by human touch, which serves as an electrical conductor used to stimulate the electrostatic field of the touch screen. However, special gloves that produce static electricity or specialized stylus pens may be used.

Capacitive touch screens are built into input devices, including all-in-one computers, smartphones and tablet PCs.

How does a Capacitive Touchscreen Work?

Capacitive touch screens are built with a thin layer of conductive material, such as copper or Indium Tin Oxide (ITO), printed onto the underside of the display's insulating outer layer. When a finger touches the screen, a small electrical charge is drawn to the point of contact, which effectively becomes a functioning capacitor. The resulting change in the electrostatic field is then measured to pinpoint where the contact took place.

Benefits of Capacitive Touch screen Technology

At present, capacitive touch screen technology offers a number of key benefits:

• High touch sensitivity and accuracy
• Support for multi-touch
• Sharp and vibrant images
• Can be used without a stylus
• Reliability - even cracked or pierced, capacitive touchscreens usually continue to function
• Popularity of the technology grants a level of future-proofing

Capacitance Touchscreen Construction

Several techniques are available to construct a capacitance touchscreen. These include conductive wire construction or the application of transparent conductive materials, such as Indium Tin Oxide (ITO), to a polyester (PET) film layer "sandwich" or to a glass substrate.
