How 'in-cell' technology could make the next iPhone ultra-thin

We’re all familiar with Apple’s love affair for thin devices. Although the third-generation iPad surprised many by gaining about half a millimeter of thickness, it looks like Apple could be back to trimming product dimensions by using a new kind of display technology in the next iPhone.
Instead of using a display comprising a number of separate layers, Apple could use in-cell touch display technology. The report says Apple would be sourcing its in-cell displays from Toshiba and Sharp.
“The advantage of in-cell is that you’re streamlining the manufacturing process, so in time you should be able to drive efficiencies and reduce cost,” IHS analyst Rhoda Alexander told Wired. “Additionally, by reducing the number of layers, you reduce the size and thickness of the device, making it thinner and lighter.”
