The touch screen portion of the front glass of an iPod or iPhone is commonly called the digitizer in technical terms. The digitizer is a clear piece that is the size of the iPod LCD screen and spans the full length and width of the clear portion of the front glass. As you press on the front glass the digitizer converts analog signals generated by your fingertip into digital signals this is what produces the touch capability. The digitizer is typically fused to the front glass of such models as the iPod Touch and iPhone. Digitizers have revolutionized how people use electronics. Without them, we wouldn’t be able to scroll through documents with our fingers, use our fingers to zoom in on pictures, or tap the front of our screen and get a reaction.
Digitizers have made life easier for the great majority of people who use them in their electronics. For example, scrolling through documents used to require that you use a scroll wheel or click mouse in order to do it quickly. Nowadays people accomplish the same functionality with a flick of their fingers on the screen of the digitizer. Because a digitizer lies on top of the LCD screen, it is usually the first item to get damaged. If you bash the iPod, iTouch or whatever piece of electronics is using the digitizer too hard, you will also damage the LCD screen below it.
Digitizers can be replaced in Apple products such as the iPhone and iPod Touch (iTouch). The latest generation iPhone 2G, 3G, and 3Gs along with the iPod Touch 1st, 2nd, and 3rd generation models have digitizer enabled touch features. The digitizer has also been introduced into many of the latest Smartphone’s and touch screen electronics on the market place. Touch operated devices use a digitizer to allow for touch functionality.
