Apple is replacing the in-cell touch screen of the iPhone 5 with the successor technique that allows even flatter displays. In addition, it will be less susceptible to interference.
The iPhone 5 and the iPod Touch is the fifth generation are equipped with an in-cell screen, wherein the touch functionality has been integrated directly into the LCD. By eliminating a separate sensor layer, the displays can be built much more compact and lighter. But the successor of the previous scheme could be called after iPhone 5S, again to another technique called “touch on display” to be installed.
