The 'folded state of the foldable electronic device (1)' and the 'folded state of the foldable housing (10)' described in the present disclosure can be interpreted as being substantially the same.

According to one embodiment, the foldable housing (10) may include a first housing (also referred to as a first housing portion or a first housing structure) (11), a second housing (also referred to as a second housing portion or a second housing structure) (12), a hinge housing (13), and/or a hinge portion (14). The first housing (11) and the second housing (12) may be connected via the hinge portion (14). The first housing (11) and the second housing (12) may be rotatable relative to each other with respect to the hinge portion (14). The hinge portion (14) may include, for example, one or more hinge modules (also referred to as hinge assemblies) (not shown).

According to one embodiment, the first display module (15) may be disposed in the foldable housing (10). The first display module (15) may include, for example, a flexible display module or a foldable display module that may be deformed in response to a transition between an unfolded state and a folded state of the foldable electronic device (1).

According to one embodiment, the first display module (15) may include a first display (e.g., a flexible display or a foldable display) (150) that provides a display area. The display area of the first display (150) may include an active area or a screen area that may display an image based on an electrical signal. The first display (150) may include a first display area (151) corresponding to the first housing (11), a second display area (152) corresponding to the second housing (12), and a third display area (153) corresponding to the hinge portion (14). The third display area (153) may extend the first display area (151) and the second display area (152).

According to one embodiment, the first display area (151) may be arranged in the first housing (11). The shape of the first display area (151) may be maintained by the support of the first housing (11). For example, the first display area (151) may be provided (or formed) to be substantially flat by being supported by the first housing (11). In the present specification, when the term "substantially" is used to define a structural part, the expression including the term "substantially" is understood or interpreted as a technical feature that is produced within the technical tolerance of the method used to manufacture it. In addition, the expression including means that a certain effect or result can be obtained within a certain tolerance, and that a person skilled in the art knows how to obtain the tolerance.

According to one embodiment, the second display area (152) may be disposed in the second housing (12). The shape of the second display area (152) may be maintained by support of the second housing (12). For example, the second display area (152) may be provided (or formed) substantially flat by being supported by the second housing (12).

According to one embodiment, the third display area (153) may be positioned corresponding to the hinge portion (14). When the foldable electronic device (1) switches between the unfolded state and the folded state, the third display area (153) may be deformed corresponding to the relative position between the first display area (151) and the second display area (152). In the unfolded state of the foldable electronic device (1), the third display area (153) may be arranged substantially flat. In the folded state of the foldable electronic device (1), the third display area (153) may be arranged in a bent form. The unfolded state of the foldable electronic device (1) may be defined or interpreted as a state in which the third display area (153) is arranged flat. The folded state of the foldable electronic device (1) may be defined or interpreted as a state in which the third display area (153) is arranged in a bent form.

According to one embodiment, in the unfolded state of the foldable electronic device (1), the first display area (151) and the second display area (152) can form an angle of about 180 degrees, and the first display (150) can be provided (or arranged) in a substantially flat form. Due to the relative positions between the first display area (151) arranged in the first housing (11) and the second display area (152) arranged in the second housing (12) in the unfolded state of the foldable electronic device (1), the third display area (153) can be arranged flat. In the unfolded state of the foldable electronic device (1), the third display area (153) can be pulled from both sides by the first display area (151) and the second display area (152), and the pulling force can be provided so as to reduce damage to the third display area (153) while allowing the third display area (153) to be placed flat. The third display area (153) can be provided (or formed) with an extended width so as to be placed flat while reducing stress caused by being pulled by the first display area (151) and the second display area (152) in the unfolded state of the foldable electronic device (1).

According to one embodiment, the first display (150) of the first display module (15) may substantially provide (or form) the front surface of the exterior of the foldable electronic device (1). The front surface of the foldable electronic device (1) may include a first front surface area provided (or formed) by the first display area (151), a second front surface area provided (or formed) by the second display area (152), and a third front surface area provided (or formed) by the third display area (153). The illustrated coordinate axes of the foldable electronic device (1) are illustrated based on, for example, the first housing (11), and the +z-axis direction may be defined or interpreted as a direction in which the substantially flat first front surface area faces. For example, the first front surface area provided (or formed) by the first display area (151) may be substantially parallel to the x-y plane. In the unfolded state of the foldable electronic device (1), the front surface of the foldable electronic device (1) can be provided (or formed) as a substantially flat surface.

According to one embodiment, in the unfolded state of the foldable electronic device (1), the hinge portion (14) can substantially support the third display area (153) of the first display module (15) in a flat manner. The hinge portion (14) can, for example, support the third display area (153) so that the third display area (153) can be arranged flatly without sagging or with reduced sagging in the unfolded state of the foldable electronic device (1), thereby reducing a crease phenomenon.

According to one embodiment, when an external force (e.g., external pressure such as a touch input using a user's finger or a touch input using an electronic pen) is applied to the third display area (153) in the unfolded state of the foldable electronic device (1), the hinge portion (14) can support the third display area (153) so that the third display area (153) can be maintained flat by reducing a sagging phenomenon of the third display area (153).

According to one embodiment, when an external impact is applied to the foldable electronic device (1) in an unfolded state, such as due to a drop, the hinge portion (14) may be configured to reduce or absorb the external impact so as to reduce the impact of the external impact on the third display area (153).

According to one embodiment, the foldable electronic device (1) may be implemented in an infolding manner in which the first display (150) of the first display module (15) (or the front surface of the foldable electronic device (1) where the display area of the first display (150) is visually visible) can be folded inward. FIG. 2 illustrates a fully folded state of the foldable electronic device (1) in which the first housing (11) and the second housing (12) are positioned so that they no longer come close. In the fully folded state of the foldable electronic device (1), the first display area (151) and the second display area (152) (or the first front area and the second front area) can face each other. For example, in a fully folded state of the foldable electronic device (1), the angle between the first housing (11) and the second housing (12) (or, the angle between the first display area (151) and the second display area (152), or the angle between the first front area and the second front area) may be from about 0 degrees to about 10 degrees. In a fully folded state of the foldable electronic device (1), the first display (150) may be substantially invisible.

Although not shown separately, the foldable electronic device (1) may be arranged in an intermediate state between the unfolded state and the fully folded state. For example, in an intermediate state of the foldable electronic device (1) in which the angle between the first housing (11) and the second housing (12) is greater than a certain angle, the foldable electronic device (1) may be configured to provide a usage environment in which a user can utilize the first display (150).

Hereinafter, the 'folded state of the foldable electronic device (1)' of the present disclosure may refer to a fully folded state in contrast to an intermediate state.

Referring to FIG. 8, the first battery (51) may include a first portion (511) and a second portion (512).

According to one embodiment, the first portion (511) of the first battery (51) may include one or more battery cells. The first portion (511) may be implemented to convert chemical energy into electrical energy.

According to one embodiment, the first part (511) of the first battery (51) may include, although not separately illustrated, a pouch (also referred to as a can, a case, a housing, or an outer shell), an electrode assembly, an electrolyte, a positive terminal (also referred to as a positive tab), and a negative terminal (also referred to as a negative tab). The pouch may provide an internal space for accommodating the electrode assembly and the electrolyte. The pouch may be formed of, for example, a metal such as aluminum or aluminum, or a non-metal such as a polymer. The electrode assembly may be formed by, for example, winding a positive plate, a negative plate, and a separator by overlapping them and rolling them together. By a series of processes of arranging the electrode assembly in the internal space of the pouch, then injecting an electrolyte, and sealing the electrode assembly, the electrode assembly may be arranged together with the electrolyte in the internal space of the pouch. The positive terminal may be electrically connected to the positive plate. The negative terminal may be electrically connected to the negative plate.

In one embodiment, the positive electrode plate of the electrode assembly can include a positive electrode substrate and a first compound coated on the positive electrode substrate. The battery capacity and voltage can be determined by the positive electrode plate. The positive electrode substrate can include, for example, a plate or layer including a metal such as aluminum (e.g., aluminum foil). The first compound can include a positive electrode active material, a conductive agent, and a binder. The positive electrode active material can include a material involved in an electrode reaction (e.g., a lithium-based oxide). The conductive agent can include a material for increasing conductivity. The binder can increase a bonding force between the positive electrode active material and the conductive agent.

In one embodiment, the negative plate of the electrode assembly can include a negative electrode substrate and a second composite coated on the negative electrode substrate.

According to one embodiment, the electrolyte of the electrode assembly is a medium that allows ions to move so that the reduction reaction or oxidation reaction of the positive and negative plates is chemically coordinated, and may include, for example, a material in a liquid, solid, or gel state. For example, when charging the first battery (51), ions (e.g., lithium ions) are released from the positive plate and moved to the negative plate through the electrolyte by oxidation of the positive plate and reduction of the negative plate, and electrons can flow from the positive plate to the negative plate along a circuit connected to the positive terminal and the negative terminal (e.g., a power management module disposed on the first printed circuit board (41) of FIG. 4, for example, a PMIC (power management integrated circuit)). For example, in the discharge of the first battery (51), ions are released from the negative plate and moved to the positive plate through the electrolyte by the reduction of the positive plate and the oxidation of the negative plate, and electrons can flow from the negative plate to the positive plate along the circuit (e.g., the power management module arranged on the first printed circuit board (41) of FIG. 4) connected to the positive terminal and the negative terminal. In the discharge, the first battery (51) can convert the chemical energy of the positive active material of the positive plate and the negative active material of the negative plate and the electrolyte into electrical energy, and supply power to the circuit (e.g., the power management module arranged on the first printed circuit board (41) of FIG. 4) through the positive terminal connected to the positive plate and the negative terminal connected to the negative plate.

According to one embodiment, the separator of the electrode assembly may be a separator disposed between the positive and negative plates, substantially preventing physical contact between the positive and negative plates.

The permittivity in the RF window region can be a value that can reduce the difference with the permittivity of air (e.g., low permittivity).

According to various embodiments, the RF window region may include, or be implemented to operate as, a dielectric lens (or electromagnetic lens).

When viewed from above the fifth side (1011A) of the third printed circuit board (1011) of the antenna module (1010), the non-conductive portion (114) can overlap with the antenna array of the antenna module (1010). The non-conductive portion (114) can be included in an RF window region corresponding to the antenna module (1010).

For example, when viewed from above the first cover (112), the second connector (C21) may be positioned closer to the first battery (51) than to the second cover member (92).

According to one embodiment, when viewed from above the first cover (112), the second connector (C21) of the second flexible printed circuit board (F2) can be positioned between the first connector (C11) of the first flexible printed circuit board (F1).

According to one embodiment, when viewed from above the first cover (112), the first flexible printed circuit board (F1) and the second flexible printed circuit board (F2) may be positioned between the fourth flexible printed circuit board (F4) and the first side portion (B1) of the first frame (111).

For example, a portion of the first flexible printed circuit board (F1) may be positioned between the first printed circuit board (41) and the second flexible printed circuit board (F2).

According to one embodiment, when viewed from above the first cover (112), the display driving circuit (72) may overlap the first flexible printed circuit board (F1) and the second flexible printed circuit board (F2).

According to one embodiment, the foldable electronic device (1) may include a display driving circuit overlapping portion (1300) that faces and overlaps the display driving circuit (72) when viewed from above the first cover (112). The display driving circuit overlapping portion (1300) may be provided (or formed) by a combination of one or more electrical components (e.g., electronic components) and/or one or more structural components.

According to one embodiment, the display driver circuit overlapping portion (1300) can be provided (or formed) as a combination of surface areas of different heights and/or surface areas of the same height through a combination of one or more components. For example, in a third direction (e.g., z-axis direction) perpendicular to the first and second directions (5001, 5002), a distance at which a portion of the display driver circuit overlapping portion (1300) is spaced from the display driver circuit (72) and a distance at which another portion of the display driver circuit overlapping portion (1300) is spaced from the display driver circuit (72) can be different. For example, in the third direction, a distance at which a portion of the display driver circuit overlapping portion (1300) is spaced from the display driver circuit (72) and a distance at which another portion of the display driver circuit overlapping portion (1300) is spaced from the display driver circuit (72) can be substantially the same.

According to one embodiment, the display driving circuit overlap portion (1300) may include a second portion (512) of the first battery (51).

According to one embodiment, the display driving circuit overlap (1300) may include a seventh side (411) facing the first cover (112) of the first printed circuit board (41).

According to one embodiment, the display driver circuit overlap (1300) may include at least one component (e.g., an electrical component or a structural component) disposed on the seventh side (411) of the first printed circuit board (41).

According to one embodiment, the display driver circuit overlap (1300) may include a second flexible printed circuit board (F2).

According to one embodiment, when viewed from above the first cover (112), the display driving circuit overlapping portion (1300) may include a first overlapping region (1301) included in the first printed circuit board (41), a second overlapping region (1302) included in the second portion (512) of the first battery (51), and a third overlapping region (1303) included in the second flexible printed circuit board (F2). When viewed from above the first cover (112), the third overlapping region (1303) may be positioned between the first overlapping region (1301) and the second overlapping region (1302) in the first direction (5001).

According to one embodiment, in a third direction (e.g., z-axis direction) perpendicular to the first and second directions (5001, 5002), a separation distance between the display driving circuit (72) and the second overlapping region (1302) may be greater than a separation distance between the display driving circuit (72) and the first overlapping region (1301) and a separation distance between the display driving circuit (72) and the third overlapping region (1303). It is highly likely that a sagging amount (or sagging displacement amount) or bending stress due to an external impact or load will substantially occur the largest in a portion of the display driving circuit (72) corresponding to the second overlapping region (1302).

According to one embodiment, the foldable electronic device (1) may include an air gap between the display driving circuit (72) and the display driving circuit overlapping portion (1300). The air gap may be interpreted as substantially not including a material capable of transmitting impact or load.

According to one embodiment, the air gap between the display driving circuit (72) and the display driving circuit overlapping portion (1300) can reduce or prevent damage to the display driving circuit (72) from an external impact or load. The air gap between the display driving circuit (72) and the display driving circuit overlapping portion (1300) can reduce stress that may occur in the display driving circuit (72) due to an external impact or load. For example, when an external impact or load is applied to at least a portion of the first cover (112) that overlaps the display driving circuit (72), the air gap between the display driving circuit (72) and the display driving circuit overlapping portion (1300) substantially does not include a material that can transmit the impact or load, and thus, compared to a comparative example in which the air gap is substantially absent, the impact or load transmitted to the display driving circuit (72) can be reduced or prevented.

According to one embodiment, the air gap between the display driving circuit (72) and the display driving circuit overlapping portion (1300) can alleviate an external impact or load. For example, when an external impact or load is applied to at least a portion of the first cover (112) that overlaps the display driving circuit (72), the air gap between the display driving circuit (72) and the display driving circuit overlapping portion (1300) induces a phenomenon in which the display driving circuit (72) sags through the air gap, thereby reducing stress concentration on the display driving circuit (72). In a comparative example in which the air gap between the display driving circuit (72) and the display driving circuit overlapping portion (1300) is substantially absent, when an external impact or load is applied to at least a portion of the first cover (112) that overlaps the display driving circuit (72), a phenomenon in which stress is concentrated on the display driving circuit (72) may occur due to the support of the display driving circuit overlapping portion (1300). In a comparative example, if at least a portion of the display driving circuit overlapping portion (1300) has substantially greater rigidity than the display driving circuit (72), when an external impact or load is applied to at least the portion of the first cover (112) that overlaps the display driving circuit (72), the phenomenon of stress being concentrated on the display driving circuit (72) may be more severe.

According to one embodiment, a thickness of an air gap between a display driving circuit (72) (or a portion of a protective sheet (80) of FIG. 7 covering the display driving circuit (72)) and a display driving circuit overlapping portion (1300) in a third direction (e.g., z-axis direction) perpendicular to the first and second directions (5001, 5002) can be provided (or formed) to a value that can reduce or prevent damage to the display driving circuit (72) from an external impact or load without hindering slimming of the foldable electronic device (1).

According to one embodiment, the thickness of the air gap between the display driving circuit (72) (or the portion of the protective sheet (80) of FIG. 7 covering the display driving circuit (72)) and the display driving circuit overlapping portion (1300) may be formed to a value that allows the display driving circuit overlapping portion (1300) to restrict bending of the display driving circuit (72) so that the display driving circuit (72) is not bent to an extent that the display driving circuit (72) is broken when the display driving circuit (72) is bent through the air gap due to an external impact or load. Restricting the display driving circuit (72) from bending beyond a certain extent may mean not generating bending stress (e.g., yield stress) that causes breakage or permanent deformation of the display driving circuit (72). Due to the bending (e.g., sagging) of the display driving circuit (72) and the support of the display driving circuit overlapping portion (1300) against external impact or load, the concentration of stress on the display driving circuit (72) can be reduced or prevented.

According to one embodiment, the air gap between the display driving circuit (72) (or the portion covering the display driving circuit (72) among the protective sheets (80) of FIG. 7) and the display driving circuit overlapping portion (1300) may be provided (or formed) with a thickness of about 0.3 mm to about 0.4 mm.

According to one embodiment, the foldable electronic device (1) may include at least one intervening member (also referred to as an intervening member) interposed in an air gap between the display driving circuit (72) (or a portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) and the display driving circuit overlapping portion (1300). The at least one intervening member may reduce a thickness of the air gap between the display driving circuit (72) (or a portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) and the display driving circuit overlapping portion (1300), thereby restricting the display driving circuit (72) from being bent to the extent of being broken through the air gap due to an external impact or load.

According to one embodiment, at least one intervening member positioned between the display driving circuit (72) (or the portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) and the display driving circuit overlapping portion (1300) may include a rigid member or an elastic member.

According to one embodiment, at least one intervening member positioned between the display driving circuit (72) (or the portion covering the display driving circuit (72) among the protective sheet (80) of FIG. 7) and the display driving circuit overlapping portion (1300) may include an impact-absorbing material (also referred to as a cushioning material). The at least one intervening member may include, for example, a first elastic member (1110) and a second elastic member (1120). The first elastic member (1110) and the second elastic member (1120) may reduce the thickness of an air gap between the display driving circuit (72) (or the portion covering the display driving circuit (72) among the protective sheet (80) of FIG. 7) and the display driving circuit overlapping portion (1300), thereby alleviating the external impact or load while restraining the display driving circuit (72) from being bent to the extent of being broken through the air gap due to the external impact or load.

According to one embodiment, the first elastic member (1110) and the second elastic member (1120) may be positioned between the display driving circuit (72) (or a portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) and the second flexible printed circuit board (F2). The first elastic member (1110) and the second elastic member (1120) may be positioned or coupled to the second flexible printed circuit board (F2). The first elastic member (1110) and the second elastic member (1120) may be coupled to the second flexible printed circuit board (F2) via, for example, an adhesive material (or an adhesive material).

When viewed from above the first cover (112), the second region (F22) may overlap the second portion (512) of the first battery (51). The first elastic member (1110) may be disposed or coupled to the first region (F21). The second elastic member (1220) may be disposed or coupled to the second region (F22). When viewed from above the first cover (112), the first elastic member (1110) and the second elastic member (1120) may not overlap.

In one embodiment, when viewed from above the first cover (112), the first area (F21) of the second flexible printed circuit board (F2) may overlap the first printed circuit board (41). When viewed from above the first cover (112), the second area (F22) of the second flexible printed circuit board (F2) may overlap the second portion (512) of the first battery (51).

According to one embodiment, in a third direction (e.g., z-axis direction) perpendicular to the first and second directions (5001, 5002), the first region (F21) of the second flexible printed circuit board (F2) and the display driving circuit (72) (or a portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) may be spaced apart by a first distance (L1). In the third direction, the second region (F22) of the second flexible printed circuit board (F2) and the display driving circuit (72) (or a portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) may be spaced apart by a second distance (L2).

In one embodiment, the first distance (L1) and the second distance (L2) can be different.

According to one embodiment, the second distance (L2) may be greater than the first distance (L1). The second flexible printed circuit board (F2) may be used in an assembly process of the foldable electronic device (1) with the first elastic member (1110) and the second elastic member (1120) attached thereto. A portion of the second flexible printed circuit board (F2) between the first region (F21) where the first elastic member (1110) is disposed and the second region (F22) where the second elastic member (1120) is disposed may be disposed in a bent manner. In a comparative example where the second flexible printed circuit board (F2) is used in the assembly process of the foldable electronic device (1) with an integral or single elastic member attached thereto replacing the first elastic member (1110) and the second elastic member (1120), the portion between the first region (F21) and the second region (F22) of the second flexible printed circuit board may be difficult to place due to the integral or single elastic member being bent.

In one embodiment, the second distance (L2) may be smaller than the first distance (L1). A portion between the first region (F21) where the first elastic member (1110) is arranged and the second region (F22) where the second elastic member (1120) is arranged among the second flexible printed circuit board (F2) may be arranged to be bent.

According to one embodiment, in a third direction (e.g., z-axis direction) perpendicular to the first and second directions (5001, 5002), a first air gap between the first elastic member (1110) and the display driving circuit (72) (or a portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) may have a third thickness (T3). In the third direction, a second air gap between the second elastic member (1120) and the display driving circuit (72) (or a portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) may have a fourth thickness (T4).

According to one embodiment, in the third direction, the first elastic member (1110) and the second elastic member (1120) can have substantially the same thickness, and the fourth thickness (T4) of the second air gap can be greater than the third thickness (T3) of the first air gap.

According to one embodiment, in the third direction, the second elastic member (1120) may be provided (or formed) thicker than the first elastic member (1110) such that the third thickness (T3) of the first air gap is substantially the same as the fourth thickness (T4) of the second air gap.

According to various embodiments, the first elastic member (1110) may have a thickness such that there is substantially no air gap between the display driving circuit (72) (or the portion of the protective sheet (80) of FIG. 7 that covers the display driving circuit (72)) and the second flexible printed circuit board (F2).
