Description

Multi-foldable electronic device including digitizer

[0001] Various embodiments of the present invention disclose a multi-foldable electronic device including a digitizer.

[0002] The use of foldable electronic devices that fold and unfold in either a horizontal or vertical direction is increasing, and various functions are being provided in foldable electronic devices.

[0003] The above foldable electronic device can be operated in a folded or unfolded state with the first housing and the second housing centered around a hinge module (e.g., a hinge member).

[0004] The foldable electronic device may include a flexible display disposed at least partially across the first housing, the hinge module, and the second housing.

[0005] The above foldable electronic device can provide a user with various information, such as text, images, and / or videos, using a flexible display.

[0006] There is growing consumer demand for expanded displays (e.g., flexible displays) in foldable electronic devices. Foldable electronic devices may be implemented in the form of multi-foldable electronic devices comprising a first housing, a second housing, and a third housing.

[0007] The above multi-foldable electronic device can be operated, for example, in an in-folding and / or out-folding manner, by rotating the first housing, the second housing, and the third housing using the first hinge member and the second hinge member.

[0008] The multi-foldable electronic device may include a flexible display disposed at least partially across the first housing, the second housing, and the third housing.

[0009] The flexible display may include a digitizer capable of inputting characters and / or pictures using an electronic pen (e.g., a stylus pen or an electro magnetic resonance (EMR) pen).

[0010] For example, the flexible display may include a first digitizer in a portion corresponding to a first housing (e.g., a first display area), a second digitizer in a portion corresponding to a second housing (e.g., a second display area), and a third digitizer in a portion corresponding to a third housing (e.g., a third display area).

[0011] When the first housing and the second housing of the multi-foldable electronic device are connected through a first hinge member (e.g., a slim hinge or a small-size hinge), and the second housing and the third housing are connected through a second hinge member (e.g., a wide hinge or a big-size hinge), if the second digitizer included in the portion corresponding to the second housing and the third digitizer included in the portion corresponding to the third housing are spaced apart from each other by a certain distance or more, signal connectivity between the second digitizer and the third digitizer may not be secured.

[0012] For example, if a second digitizer disposed on a second housing of a multi-foldable electronic device and a third digitizer disposed on a third housing are spaced apart from each other by a certain distance (e.g., about 10 to 15 mm) in an area where the second hinge member is disposed, a signal may not be transmitted between the second digitizer and the third digitizer.

[0013] Various embodiments of the present invention may provide a multi-foldable electronic device including a digitizer (e.g., a fourth digitizer) disposed inside a second hinge member (e.g., a second folding hinge) connecting a second housing and a third housing.

[0014] The technical problems to be achieved in the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary skill in the technical field to which the present invention pertains from the description below.

[0015] According to one embodiment of the present invention, a multi-foldable electronic device may include a first housing, a second housing foldably and unfoldably coupled to a first side of the first housing, a third housing foldably and unfoldably coupled to a second side of the second housing, a first hinge member connected between the first housing and the second housing, and a second hinge member connected between the second housing and the third housing. According to one embodiment, the multi-foldable electronic device may include a flexible display arranged over the first housing, the second housing, and the third housing. According to one embodiment, the multi-foldable electronic device may include a first digitizer arranged on the first housing, a second digitizer arranged on the second housing, a third digitizer arranged on the third housing, and a fourth digitizer arranged on the second hinge member.

[0016] According to various embodiments of the present invention, a signal connection between a second digitizer disposed on the second housing and a third digitizer disposed on the third housing can be stably secured by using a digitizer (e.g., a fourth digitizer) disposed on a second hinge member connecting the second housing and the third housing.

For example, if the electronic device (101) includes a main processor (121) and a secondary processor (123), the secondary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a specified function. The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0033] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0048] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)).

In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas by, for example, the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0050] According to various embodiments, the antenna module (197) may form a mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0051] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

A third digitizer (530) may be disposed on the third housing (230). A fourth digitizer (540) may be disposed on the second hinge member (202).

[0105] According to one embodiment, the first housing (210) can be foldably and unfoldably coupled to a first side (e.g., in the x-axis direction) of the second housing (220) via a first hinge member (201). The first hinge member (201) can be operatively connected between the first housing (210) and the second housing (220). The first hinge member (201) can be arranged such that the first housing (210) and the second housing (220) can be foldably and unfoldably relative to each other. The first hinge member (201) can be arranged at a position corresponding to a first bending area (501) of the flexible display (240). For example, the first bending area (501) can be formed between the first digitizer (510) and the second digitizer (520). For example, when the first housing (210) is folded relative to the second housing (220), the first bending area (501) can form a first folding portion (F1) between the first display area (240a) and the second display area (240b) of the flexible display (240).

The second hinge member (202) can be operatively connected between the second housing (220) and the third housing (230). The second hinge member (202) can be arranged such that the second housing (220) and the third housing (230) can be foldably and unfoldably connected to each other. The second hinge member (202) can be arranged at a position corresponding to the second bending area (502) and the third bending area (503) of the flexible display (240). For example, the second bending area (502) may be formed between the second digitizer (520) and the fourth digitizer (540). For example, the third bending area (503) may be formed between the third digitizer (530) and the fourth digitizer (540). For example, when the third housing (230) is folded with respect to the second housing (220), the second bending area (502) and the third bending area (503) may form a second folding portion (F2) and a third folding portion (F3) between the second display area (240b) and the third display area (240c) of the flexible display (240). For example, the fourth digitizer (540) may be positioned between the second bending area (502) and the third bending area (503) and on the second hinge member (202).

[0108] According to one embodiment, the first housing (210) and the second housing (220) can smoothly fold and unfold through the first hinge member (201) and the first bending region (501). The second housing (220) and the third housing (230) can smoothly fold and unfold through the second hinge member (202), the second bending region (502), and the third bending region (503).
