Simply put, the digitizer is your iPhone’s touchscreen. In more detail, the digitizer is a glass panel that converts your touch into signals that your iPhone uses to do what you want. The digitizer is not actually the glass that you touch; it is underneath the top (protective) layer of glass. That’s why, generally, when you break the glass on your iPhone, your touchscreen still works. Check out Cell Phone City’s iPhone page for a quote to get your iPhone screen replaced.
On older iPhone models (4S and older) the digitizer was actually attached directly to the top layer of glass. That engineering (glass on glass) resulted in more cases of the touchscreen malfunctioning when the iPhone screen was broken. Newer iPhone models (iPhone 5 and newer) are built with the digitizer attached to the LED screen instead, leaving a few more layers on construction in between the top glass and the digitizer. This new construction offers better touch response, as well as some extra protection to the digitizer.
Most new aftermarket iPhone replacement screens have the old digitizer technology in them to cut down on costs. If you look at your iPhone screen replacement and it seems shinier than the original screen that cracked. Your eyes may not be playing tricks on you. When the digitizer is attached to the top glass it results in much more glare. The new replacement screens are responding well to touch, but do have subtle differences when compared to premium replacement and OEM screens.
