A capacitive screen on a mobile phone or smartphone usually has a glass face and doesn't rely on pressure. This makes it more responsive than a resistive screen when it comes to gestures such as swiping and pinching. Capacitive touchscreens can only be touched with a finger, and will not respond to touches with a regular stylus, gloves or most other objects.
Apple's iPhone wasn't the first capacitive touchscreen consumer smartphone on the market that honour goes to the LG Prada , but it has been one of the most popular since its launch in Though resistive touchscreens are often quite responsive — especially in many new smartphones hitting the market — capacitive touchscreens usually provide a more pleasant user experience. Actions like swiping through contact lists, zooming in and out of Web pages and maps, typing e-mails and text messages and scrolling through photos are best suited to capacitive touchscreens; unlike resistive screens, you can swipe across them gently and still get a response.
Resistive screens are often found in cheaper devices, as they cost significantly less to manufacture. Become a fan of GoodGearGuide on Facebook. Stay up to date with the latest reviews. The iPhone can detect the difference between your pressing the screen with one, two, three or four fingers. It can also detect gestures such as swiping or pinching. This sensitivity gives you a much wider range of controls for each individual application.
It also helps make the user interface much more intuitive. For example, programmers can map your finger swipes to scrolling through a long page, or pulling two fingers apart to zoom in on an image.
Capacitive touch screens such as the iPhone are configured to detect the conductivity level of a human finger.
This means that most other objects such as a pen or stylus won't work, limiting the possibilities for applications that rely on precise positioning and movement, such as drawing apps. Electronic devices can use lots of different methods to detect a person's input on a touch screen. Most of them use sensors and circuitry to monitor changes in a particular state. Many, including the iPhone, monitor changes in electrical current. Others monitor changes in the reflection of waves.
These can be sound waves or beams of near-infrared light. A few systems use transducers to measure changes in vibration caused when your finger hits the screen's surface or cameras to monitor changes in light and shadow. The basic idea is pretty simple -- when you place your finger or a stylus on the screen, it changes the state that the device is monitoring.
In screens that rely on sound or light waves, your finger physically blocks or reflects some of the waves. Capacitive touch screens use a layer of capacitive material to hold an electrical charge; touching the screen changes the amount of charge at a specific point of contact.
