[0035] 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 supported by the second housing (12) and provided (or formed) to be substantially flat.

[0036] 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 an unfolded state and a 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 shape. 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 shape.

[0037] 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 placing the third display area (153) flat. The third display area (153) can be provided (or formed) with an extended width so as to be placed flat while reducing stress due to being pulled by the first display area (151) and the second display area (152) in the unfolded state of the foldable electronic device (1).

[0038] 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 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 the 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 xy 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.

[0039] According to one embodiment, in the unfolded state of the foldable electronic device (1), the hinge portion (14) can support the third display area (153) of the first display module (15) substantially flat. The hinge portion (14) can, for example, support the third display area (153) so that the third display area (153) can be placed flat without sagging or with reduced sagging in the unfolded state of the foldable electronic device (1), thereby reducing a crease phenomenon.

[0040] 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 the sagging phenomenon of the third display area (153).

[0041] 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).

[0042] 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 to each other. 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) may 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.

[0043] 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 user environment in which the user can utilize the first display (150).

[0244] FIG. 8 is a drawing showing a first battery (51) and a first flexible printed circuit board (F1) according to one embodiment of the present disclosure, and a cross-sectional view of the first battery (51) taken along line G-G'.

[0245] Referring to FIG. 8, the first battery (51) may include a first portion (511) and a second portion (512).

[0246] 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 configured to convert chemical energy into electrical energy.

[0247] 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, for example, by winding a positive plate, a negative plate, and a separator by overlapping them and rolling them together. The electrode assembly may be arranged together with the electrolyte in the internal space of the pouch by a series of processes of arranging the electrode assembly in the internal space of the pouch, then injecting the electrolyte, and sealing the electrode assembly. The positive terminal may be electrically connected to the positive plate. The negative terminal may be electrically connected to the negative plate.

[0248] In one embodiment, the positive electrode plate of the electrode assembly may include a positive electrode substrate and a first compound coated on the positive electrode substrate. The battery capacity and voltage may be determined by the positive electrode plate. The positive electrode substrate may include, for example, a plate or layer (e.g., aluminum foil) comprising a metal such as aluminum. The first compound may include a positive electrode active material, a conductive agent, and a binder. The positive electrode active material may include a material involved in an electrode reaction (e.g., a lithium-based oxide). The conductive agent may include a material for enhancing conductivity. The binder may enhance the bonding strength between the positive electrode active material and the conductive agent.

[0249] In one embodiment, the negative electrode plate of the electrode assembly may include a negative electrode substrate and a second composite coated on the negative electrode substrate. The negative electrode substrate may include, for example, a plate or layer (e.g., copper foil) comprising a metal such as copper.

The conductive agent may include a material for enhancing conductivity. The binder may enhance the bonding strength between the negative electrode active material and the conductive agent.

[0250] According to one embodiment, the electrolyte of the electrode assembly is a medium that allows ions to move so that the reduction 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.

[0251] In 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 separator may prevent short circuits between the positive and negative plates and may enable the movement of ions. The separator may enable the flow of charges by allowing ions to move through microscopic pores, for example, and may be formed of various porous materials.

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).

[0315] According to one embodiment, when viewed from above the first cover (112), the second connector (C21) of the second flexible printed circuit board (F2) may be positioned between the first connector (C11) of the first flexible printed circuit board (F1).

[0316] 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).

[0317] According to one embodiment, when viewed from above the first cover (112), the second flexible printed circuit board (F2) may overlap the first flexible printed circuit board (F1). 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).

[0318] 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).

[0319] 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.

[0320] According to one embodiment, the display driver circuit overlapping portion (1300) may 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., the z-axis direction) perpendicular to the first and second directions (5001, 5002), the distance by which any part of the display driver circuit overlapping portion (1300) is spaced from the display driver circuit (72) may be different from the distance by which any other part of the display driver circuit overlapping portion (1300) is spaced from the display driver circuit (72). For example, in the third direction, the distance by which any part of the display driver circuit overlapping portion (1300) is spaced from the display driver circuit (72) may be substantially the same.

[0321] According to one embodiment, the display driving circuit overlapping portion (1300) may include a second portion (512) of the first battery (51).

[0322] According to one embodiment, the display driver circuit overlapping portion (1300) may include a seventh side (411) of the first printed circuit board (41) facing the first cover (112).

[0323] 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).

[0324] According to one embodiment, the display driver circuit overlay (1300) may include a second flexible printed circuit board (F2).

[0325] According to one embodiment, when viewed from above the first cover (112), the display driving circuit overlapping portion (1300) may include a first overlapping area (1301) included in the first printed circuit board (41), a second overlapping area (1302) included in the second portion (512) of the first battery (51), and a third overlapping area (1303) included in the second flexible printed circuit board (F2). When viewed from above the first cover (112), the third overlapping area (1303) may be positioned between the first overlapping area (1301) and the second overlapping area (1302) in the first direction (5001).

[0326] 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 may be highly likely that the amount of deflection (or amount of deflection displacement) or bending stress due to an external impact or load will substantially be the largest in a portion of the display driving circuit (72) corresponding to the second overlapping region (1302).

[0327] 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 containing a material capable of transmitting impact or load.

[0328] 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 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 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 capable of transmitting 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.

[0329] 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 the display driving circuit (72) to sag through the air gap, thereby reducing stress concentration on the display driving circuit (72). In a comparative example where 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.

[0330] According to one embodiment, the thickness of 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) in a third direction (e.g., z-axis direction) perpendicular to the first and second directions (5001, 5002) can be provided (or formed) at a value that can reduce or prevent damage to the display driving circuit (72) from external impact or load without hindering slimming of the foldable electronic device (1).

[0331] 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 that covers 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) does not bend 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.

[0332] According to one embodiment, the 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 display driving circuit overlapping portion (1300) may be provided (or formed) with a thickness of about 0.3 mm to about 0.4 mm.

[0333] 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 the portion covering the display driving circuit (72) among the protective sheets (80) of FIG. 7) and the display driving circuit overlapping portion (1300). The at least one intervening member may reduce the thickness of 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), 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.

[0334] 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.

[0335] 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 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 the 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 display driving circuit overlapping portion (1300), thereby mitigating the external impact or load while preventing 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.

[0336] 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 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). The first elastic member (1110) and the second elastic member (1120) may be disposed 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 bonding material).

[0337] In one embodiment, the first elastic member (1110) and / or the second elastic member (1120) may include, but is not limited to, a sponge.

[0338] According to one embodiment, when viewed from above the first cover (112), the second flexible printed circuit board (F2) may include a first region (F21) and a second region (F22). When viewed from above the first cover (112), the first region (F21) may overlap the first printed circuit board (41). 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.

[0339] According to 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).

[0340] 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 the 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 the 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).
