What is “Touchscreen”? Which one is best? “Capacitive touchscreen” or “Resistive touchscreen”?

A touchscreen display is one that is sensitive to touch. They are often used on smartphones and similar devices. In the cell phone industry there are two major categories of touchscreen displays: “Capacitive touchscreens” and “Resistive touchscreens”.

What is “Capacitive touchscreen”?

Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touching. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand.

Examples of devices with Capacitive touchscreens are the Apple iPhone, Nokia Lumia 620 and the Sony Xperia p.

What is “Resistive touchscreen”?

Resistive touchscreen displays are composed of multiple layers that are separated by thin spaces. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching. As such, resistive type touchscreens require much more pressure to activate than capacitive touchscreens.

Examples of devices with Resistive touchscreens are the HTC Touch Diamond, Nokia Asha 305 and the Samsung SGH-i900
