There are also many aftermarket quality screens in the market that can be directly used to transplant the original IC, such as RJ INCELL, JK INCELL, ZY INCELL, etc. . However, due to the characteristics of some iPhone screens like iPhone 13 mini, the screen touch IC transplantation methods are somewhat different, and other components are required to make the transplanted IC function normally.
