Description

Technical Field

[0001] Various embodiments relate to foldable electronic devices that include multiple digitizers. Background Technology

[0002] Digitizers, included in electronic devices, are being developed to receive various inputs from users via an input device (e.g., a stylus). A digitizer can determine the location of a specified electronic device and perform corresponding functions using an input device with pen functionality (which may be referred to as a "stylus" for ease of description in this disclosure).

[0003] Electronic devices can use electromagnetic resonance (EMR) methods to detect magnetic field signals, including the resonant frequency generated by a stylus, via a digitizer. The digitizer can then generate a signal to determine the stylus's position based on the induced electromotive force generated by the magnetic field produced by the stylus. Summary of the Invention

[0004] Technical issues

[0005] In a foldable electronic device with multiple housings, a digitizer can be installed inside each of the housings, and a controller can be installed inside one of the housings. The controller can be connected to multiple digitizers installed inside the housings.

[0006] In a foldable electronic device with multiple housings, a connector-to-connector flexible printed circuit board (C2C FPCB) can be provided between two adjacent housings, and at least a portion of the wires connecting digitizers disposed inside the two adjacent housings and / or at least a portion of the wires connecting the controller and the digitizers can be located on the C2C FPCB. Multiple digitizers electrically connected to a single controller can degrade the performance of the digitizers in the foldable electronic device and increase the number of pins provided in the C2C FPCB connecting the multiple digitizers.

[0007] According to various embodiments of the present disclosure, an electronic device may include a first conductive line in a first digitizer contained within a first housing and a second conductive line in a second digitizer contained within a second housing, and may have the following structure: wherein the first conductive line and the second conductive line form a closed loop, and wherein the conductive line included in the digitizer within the housing in which no controller is provided is connected to a reference line.

[0008] Technical solution

[0009] An electronic device according to an embodiment may include: a first housing; a second housing connected to the first housing for rotation about a rotation axis; a first digitizer located in the first housing and including a plurality of first conductive lines; a second digitizer located in the second housing and including a plurality of second conductive lines; and a controller located in the first housing. The first ends of the plurality of first conductive lines may be respectively connected to a plurality of signal output terminals of the controller. The second ends of the plurality of first conductive lines are respectively connected to the first ends of the plurality of second conductive lines. Furthermore, the second ends of the plurality of second conductive lines may be respectively connected to reference lines extending from a reference terminal of the controller into the second digitizer.

[0010] An electronic device according to an embodiment may include: a plurality of housings connected to be rotatable about one or more rotation axes; a plurality of digitizers, each located within one of the housings; and a controller located within one of the housings. A first digitizer among the plurality of digitizers may include a first conductive line. A second digitizer among the plurality of digitizers may include a second conductive line. A first end of the first conductive line may be connected to a first signal output terminal of the controller. A second end of the first conductive line may be connected to a first end of the second conductive line. A second end of the second conductive line may be connected to a first reference line extending from a first reference terminal of the controller into the second digitizer, and the distance between the first digitizer and the controller may be less than the distance between the second digitizer and the controller.

[0011] Beneficial effects

[0012] According to an embodiment, a foldable electronic device comprising a plurality of digitizers can be provided. The electronic device according to an embodiment may include a first conductive line in a first digitizer contained within a first housing and a second conductive line in a second digitizer contained within a second housing, and may have the following structure: wherein the first conductive line and the second conductive line form a closed loop, and wherein the conductive line included in the digitizer within the housing that does not have a controller is connected to a reference line.

[0013] When the reference line is connected to the conductive lines included in the digitizer inside the housing where the controller is located, the conductive lines included in the digitizer inside the housing where the controller is not located can be connected to the signal output terminal of the controller. To connect the conductive lines included in the digitizer inside the housing where the controller is not located to the signal output terminal of the controller, the number of conductive lines on the C2C FPCB must be equal to the number of closed loops formed; therefore, a large number of pins can be included on the C2C FPCB.

[0014] On the other hand, in the electronic device according to the embodiment, the conductive lines included in the digitizer inside the housing without a controller can be connected to the reference line, and the wires extending from the reference line to the digitizer inside the housing without a controller can be provided on the C2C FPCB, thereby reducing the number of pins included in the C2C FPCB.

According to various embodiments, the foldable electronic device 300 (e.g., electronic device 101 or foldable electronic device 200a) may include a first printed circuit board assembly (PBA) 310, a second PBA 320, a first digitizer 340, a second digitizer 350, a first FPCB 345, a second FPCB 355, a first C2C FPCB 361 and / or a second C2C FPCB 362.

Reference Figure 2a and Figure 2b According to various embodiments, the first housing in which the first PBA 310, the first digitizer 340, and the first FPCB 345 are located can be Figure 2a and Figure 2b Either the first housing 210a or the second housing 220a shown. According to various embodiments, the second housing in which the second PBA 320, the second digitizer 350, and the second FPCB 355 are located can be... Figure 2a and Figure 2b The other of the first housing 210a and the second housing 220a.

[0057] According to various embodiments, controller 330 (e.g., auxiliary processor 123) may be arranged on the first PBA 310.

[0058] According to various embodiments, a first digitizer 340 may include multiple conductive lines 341, 342, and 343 to generate a signal for determining the position of the stylus based on a pen signal generated from the stylus. According to various embodiments, a second digitizer 350 may include multiple conductive lines 351, 352, and 353 to generate a signal for determining the position of the stylus based on a pen signal generated from the stylus. According to various embodiments, the multiple conductive lines 341, 342, and 343 and the multiple conductive lines 351, 352, and 353 may each form an open loop, and changes in the magnetic field generated by the stylus passing through the interior of the open loop can induce current in the multiple conductive lines 351, 352, and 353 and the multiple conductive lines 341, 342, and 343. According to various embodiments, the magnetic field generated from the stylus can be referred to as the pen signal, and the current induced in the multiple conductive lines 351, 352 and 353 included in the first digitizer 340 and the multiple conductive lines 341, 342 and 343 included in the second digitizer 350, or the voltage induced at both ends of the multiple conductive lines based on the pen signal, can be used as a signal for determining the position of the stylus.

[0059] According to various embodiments, the stylus can generate a signal including a resonant frequency by using a resonant circuit included in a printed circuit board disposed within the stylus. For example, when an AC voltage is applied to multiple conductive lines of digitizers 340 and 350, a magnetic field can be formed, and according to the law of electromagnetic induction, current can flow through the conductive lines inside the stylus adjacent to digitizers 340 and 350, thereby generating a signal including a resonant frequency through the resonant circuit inside the stylus, which can be recognized by digitizers 340 and 350. The resonant circuit may include electronic components, such as at least one conductive line (coil), an inductor, and / or a capacitor. According to embodiments, the resonant circuit can be used to change the strength or frequency of the electromagnetic field according to the user's operating state. For example, the resonant circuit can provide various frequencies for recognizing hover input, drawing input, button input, or erase input.
