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.
Projected Capacitive Touchscreens
Projected Capacitive (PCap) touchscreens are used on the vast majority of smartphones and tablets. PCap screens consist of a layer of glass, a matrix of electrodes and a protective film. The matrix of electrodes creates a three dimensional electrostatic field that registers even the slightest change in electrical current. So, when a conductive object, such as your finger or a stylus, comes into contact with the matrix of electrodes, the electric field is changed slightly, and the screen registers your touch
Capacitive Touchscreen Advantages
A capacitive touchscreen:
- Offers easy, flexible operation. A capacitive touchscreen comprises two layers of glass, coated with a conductor agent, like iridium tin oxide. The conductor agent reacts to the touch of a human finger or special-tipped stylus on the screen. This causes a change in the local electrostatic field and indicates to the system exactly which area, number, or icon on the screen has been touched. A capacitive touchscreen also supports multi-touch—e.g., simultaneous pressing on an icon and enlargement of an image on the screen.
- Touts a higher degree of contrast. A capacitive touchscreen can be seen more easily.
- Facilitates more accurate input. Because there is little or no leeway for the capacitive touchscreen system to interpret input inaccurately, the potential for errors—whether in transaction or in customer order detail—is minimized
- Features enhanced durability. A capacitive touchscreen can, in certain ways, be more durable than its resistive counterpart. Why? Frequently used areas on a capacitive touchscreen do not typically start to break down and become unresponsive over time and with heavy use. Additionally, a capacitive touchscreen that is scratched, pierced, or cracked will continue to operate. This can occur if employees try to operate the device with something other than their finger or stylus, if they tap the glass too hard, or if a mobile device is dropped. This is not true of a resistive touchscreen, which in most cases stops working whenever the surface is damaged.
Because a capacitive touchscreen keeps working even if it suffers damage, there’s no need to interrupt store or restaurant operations in order to install a replacement. This minimizes customer frustration and lost sales.

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.
