Abstract: A flexible printed circuit board includes a coil for near-field communication (NFC) and circuit components for performing other functions such as driving a display panel. By integrating the NFC coil into the flexible printed circuit board, the number of components in an electronic device may be reduced. A ferrite sheet is provided below the NFC coil to enhance the performance of NFC signal reception and transmission. A conductive layer is provided below the ferrite sheet to prevent interference with circuits on a printed circuit board below the flexible printed circuit board.
