Compared with on-cell technology, touch panels that use in-cell technology can be made thinner because the touch sensors are actually placed inside the color filters rather than on top of them, he explained.The occasionally-reliable Digitimes is reporting similar claims based on "sources in Apple's supply chain", indicating that improvements in yield rates for the in-cell panels have made it feasible for Apple to use the technology in its products. According to the report, Sharp and Toshiba will be ramping up their production of in-cell panels this quarter.
At present, Taiwan's TPK Holding Co. and Wintek Corp., which supply touch panels to Apple, use mainly on-cell technology in their products, according to the two companies.
