Patent Description:
A digitizer included in an electronic device is being developed to receive various inputs from a user through an input device (e.g., a stylus pen). The digitizer may identify the location on a specified electronic device by an input device having a pen function (which may be referred to as a "stylus pen" for the convenience of description in the disclosure) and perform a function corresponding thereto.

The electronic device may detect a magnetic field signal including a resonance frequency generated from a stylus pen through a digitizer using an electromagnetic resonance (hereinafter referred to as EMR) method. The digitizer may generate a signal for identifying the location of a stylus pen, based on an induced electromotive force generated by the magnetic field generated from the stylus pen. <CIT> provides details of a foldable electronic device featuring a flexible display and a hinge mechanism that allows the device to transition between folded and unfolded states. The device comprises two housing portions connected by the hinge, each accommodating various electronic components. Flexible printed circuit boards (FPCBs) extend across the hinge area, accommodating bending motions without compromising signal integrity.

In a foldable electronic device having a plurality of housings, a digitizer may be disposed inside each of the plurality of housings, and a controller may be disposed inside one of the plurality of housings.

The plurality of digitizers electrically connected to one controller may reduce the performance of the digitizer in a foldable electronic device and increase the number of pins provided in the C2C FPCBs connecting the plurality of digitizers.

According to various embodiments of the disclosure, an electronic device may include a first conductive line included in a first digitizer inside a first housing and a second conductive line included in a second digitizer inside a second housing, and may have a structure in which the first conductive line and the second conductive line form a closed loop and in which a conductive line included in a digitizer inside a housing in which the controller is not disposed, among the first conductive line and the second conductive line, is connected to a reference line.

An electronic device according to an embodiment may include a first housing, a second housing connected to the first housing to be rotatable about a rotation axis, a first digitizer positioned in the first housing and including a plurality of first conductive lines, a second digitizer positioned in the second housing and including a plurality of second conductive lines, and a controller positioned in the first housing, wherein first ends of the plurality of first conductive lines may be respectively connected to a plurality of signal output ends of the controller, wherein second ends of the plurality of first conductive lines may be respectively connected to first ends of the plurality of second conductive lines, and wherein second ends of the plurality of second conductive lines may be respectively connected to reference lines extending from reference ends of the controller into the second digitizer.
