Touchscreens
You can do things like swipe your fingers across the screen to find your contacts and your favourite music. Some phones like the iPhone even let you 'pinch' the screen to make it smaller. There are two types of touchscreens: capacitive and resistive.
|
Capacitive touchscreen | Resistive touchscreen |
| Doesn't react to inanimate objects (like a stylus pen, fingernail or gloved finger) | Reacts to pressure, whether you use your finger or an inanimate object like a stylus pen |
| Potentially very accurate to within a few pixels, but in reality this is limited to the size of your fingertips | Good for handwriting recognition and for those who have big fingers |
| Made of glass so though it's not shatter-proof, it's fairly resistant to casual scratches | Won't shatter because it's not made of glass but since it has a softer top layer, it's more prone to wear and tear |
| Examples of capacitive touchscreens: iPhone, HTC Desire, Samsung Wave | Example of a resistive touchscreen: Nokia 5800 |
Keep your screen pristine
If you have a touchscreen phone, it's vital you use a screen protector to keep it looking its best and ward off any cracks or scratches. Screen protectors (also called guards or shields) don't affect your touchscreen's responsiveness and are really easy to stick on - this eye opener video shows you how.
