According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In some embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).

The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to one embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134.

For example, when the electronic device 101 includes the main processor 121 and the auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be specific to a specified function. The auxiliary processor 123 may be implemented as separate from, or as part of the main processor 121.

The display module 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. According to an embodiment, the display module 160 may include a touch sensor adapted to detect a touch, or a pressure sensor adapted to measure the intensity of force incurred by the touch.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an 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 (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the 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., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may 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 some embodiments, at least a portion of the second extension member 222 may be replaced with the second rear surface cover 223. For example, the entire second extension member 222 may be replaced with the second rear surface cover 223. In this example, the first extension member 222 is thus absent.

According to various embodiments, the electronic device 200 may include a rollable display 230 disposed to be supported by at least a portion of the first housing 210 and at least a portion of the second housing 220. According to an embodiment, the rollable display 230 may include: a first portion 230a (e.g., a flat portion) that is always visible from the outside; and a second portion 230b (e.g., a bendable portion) extending from the first portion 230a and at least partially accommodated in the first space 2101 of the first housing 210 to be invisible from the outside in the slide-in state. According to an embodiment, the first portion 230a may be disposed to be supported by the second housing 220, and the second portion 230b may be disposed to be at least partially supported by the support member (e.g., the support member 240 in FIG. 4). According to an embodiment, in the state in which the second housing 220 is slid out along a first direction (direction {circle around (1)}), the second portion 230b of the rollable display 230 may extend from the first portion 230a while being supported by the support member (e.g., the support member 240 in FIG. 4), and may be disposed to be substantially coplanar with the first portion 230a and to be visible from the outside.

Accordingly, in the electronic device 200, the display area of the rollable display 230 may be variable, since the second housing 220 is movable in a sliding manner from the first housing 210 in a predetermined direction (e.g., +y-axis direction). In particular, the display area of the rollable display 230 may be varied through sliding the second housing 220 in or out.

According to various embodiments, the rollable display 230 may be variable in length in the first direction (direction {circle around (1)}) according to the sliding of the second housing 220 that is moved with reference to the first housing 210. For example, in the slide-in state, the rollable display 230 may have a first display area corresponding to a first length L1 (e.g., an area corresponding to the first portion 230a). According to an embodiment, in the slide-out state, according to the sliding of the second housing 220 further moved by a second length L2 with reference to the first housing 210, the rollable display 230 may be expanded to have a third display area (e.g., an area including the first portion 230a and the second portion 230b), which corresponds to a third length L3 longer than the first length L1 and is larger than the first display area.

The transmission area may include an area overlapping the effective area (e.g., the view angle area) of the first camera module 205 through which light imaged by an image sensor to generate an image passes. For example, the transmission area of the rollable display 230 may include an area having a lower pixel arrangement density and/or wiring density than the surrounding area. For example, the transmission area may replace the above-mentioned openings. For example, some camera modules 205 may include an under-display camera (UDC). In some embodiments, one or more sensor modules 204 may be disposed to perform the functions thereof in the internal space of the electronic device 200 without being visually exposed through the rollable display 230.

The display area 230-1, the accommodation area 230-2, and the bending area 230-3 are conceptually divided into respective areas of the rollable display 230 for convenience of description. Accordingly, respective areas may not be physically or visually differentiable. For example, when the rollable display is moved from a slide-in state to a slide-out state, or vice versa, the parts of the display area referred to as the display area 230-1, the accommodation area 230-2, and the bending area 230-3 may change accordingly. The display area 230-1 may be an area in which the rollable display 230 is visually recognized from the outside of the electronic device 200. Through the display area 230-1, the user may identify visual information displayed through the rollable display 230. The accommodation area 230-2 may be an area in which the rollable display 230 is accommodated into the electronic device 200. The accommodation area 230-2 is a portion covered by other mechanical objects (e.g., the first housing 210, the second housing 220, the first extension member 212, the second extension member 222, and the like), and may be an area that is not visually recognized from the outside of the electronic device 200. The bending area 230-3 may be an area between the display area 230-1 and the accommodation area 230-2. The bending area 230-3 may be a deformed area of the rollable display 230. The support member 240 bent according to the shape of the guide rails 226 may support the bending area 230-3. Unlike the display area 230-1 and the accommodation area 230-2 which are substantially parallel to the sliding direction of the electronic device 200 (e.g., the Y direction in FIG. 6A), the bending area 230-3 may be an area in which the rollable display 230 is maintained in a deformed state.

In various embodiments, when the second housing 220 is slid relative to the first housing 210 in direction {circle around (1)}, the display area 230-1 may increase and the accommodation area 230-2 may decrease. In contrast, when the first housing 210 is slid relative to the second housing 220 in direction {circle around (2)}, the display area 230-1 may decrease and the accommodation area 230-2 may increase. The above-described sliding of the first housing 210 may be automatically executed by the driving motor 260.

According to various embodiments, the driving motor 260 and electronic components (e.g., the first printed circuit board 251 and the battery B) arranged in the first housing 210 may move together according to the slide-in/slide-out operation of the first housing 210. There, compared to the arrangement structure in which the corresponding components are arranged in the second housing 220 and connected to the first printed circuit board 251 via electrical connection members, the number of electrical connection members are minimized, which may help improve the operation reliability of the electronic device 200 and to design an efficient arrangement of electronic components.

Electronic devices according to various embodiments disclosed in this document will be described as a first embodiment and a second embodiment, respectively. Since the electronic devices according to the first embodiment and the second embodiment include elements similar to those of the electronic device 200 described above, redundant descriptions of the elements will be omitted, and, unless necessary, descriptions will be made using the same reference numeral for the same or similar element. If necessary, the above description of the electronic device 200 may be referred to description of the first and second embodiments.

FIG. 7 is a perspective view of an electronic device according to a first embodiment disclosed in this document. FIG. 8 is a perspective view of an electronic device according to a second embodiment disclosed in this document.

FIGS. 7 and 8 may be perspective views illustrating the state in which some elements of the electronic device are removed. For example, FIGS. 7 and 8 may be perspective views illustrating the state in which a first housing (e.g., the first housing 210 in FIG. 2A) of the electronic device is removed.

An electronic device 300 of the first embodiment and an electronic device 400 of the second embodiment may include a first housing 210 and a second housing 220 slidably coupled to each other in a similar manner as the electronic device 200 described with reference to the drawings above. The electronic device 300 of the first embodiment and the electronic device 400 of the second embodiment may include a rollable display 230. According to sliding of the first housing 210 and the second housing 220, a display area (e.g., the display area 230-1 in FIGS. 6A and 6B) and an accommodation area (e.g., the accommodation area 230-2 in FIGS. 6A and 6B) of the rollable display 230 may increase or decrease. The sliding of the second housing 220 relative to the first housing 210 may be performed automatically through a moving part. The moving part may include a driving motor (e.g., the driving motor 260 in FIG. 4) The moving part may additionally include a pinion gear connected to the driving motor (e.g., the pinion gear 261 in FIG. 4), and a rack gear (e.g., the rack gear 2251 in FIG. 4) meshed with the pinion gear. The rack gear may be formed to extend along a sliding direction (e.g., the Y direction in FIGS. 7 and 8) of the electronic device 300 or 400. For example, the driving motor may be fixed to the first housing 210, and the rack gear may be formed to extend in a sliding direction of the electronic device 300 or 400 so as to be fixed to the second housing 220. According to the operation of the driving motor, the pinion gear meshed with the rack gear rotates, so that the first housing 210 may slide relative to the second housing 220.

Referring to FIGS. 7 and 8, the electronic device 300 of the first embodiment and the electronic device 400 of the second embodiment may include rear covers 600 and 700 (e.g., the rear bracket 214 in FIG. 4). Referring also to FIG. 4, the rear covers 600 and 700 may be disposed in the second housing 220 so as to cover a printed circuit board (e.g., the first board 251 in FIG. 4) disposed in the second housing 220.

According to various embodiments, the rear covers 600 and 700 may be exposed to the outside or covered by the first housing 210 according to sliding operation of the second housing 220 relative to the first housing 210. Here, the state in which the rear covers 600 and 700 are exposed to the outside may be understood as the rear covers 600 and 700 protruding from the first housing 210 (see FIG. 3B). In addition, the state in which the rear covers 600 and 700 are exposed to the outside may indicate the state in which at least a portion of the rear covers 600 and 700 is visible from the outside or the state in which the rear covers 600 and 700 are visible from the outside through a cover glass member (e.g., the first rear cover 213 in FIG. 4) disposed in the rear covers 600 and 700. A cover glass member 213 may be disposed in the rear covers 600 and 700. When the second housing 220 slides relative to the first housing 210, the cover glass member 213 disposed in the rear covers 600 and 700 may be visible from the outside of the electronic devices 300 and 400. At least a portion of the cover glass member 213 may be formed of a transparent material. Accordingly, a portion of the rear covers 600 and 700 may be visible through the cover glass member 213. In addition, if the second housing 220 slides relative to the first housing 210, the side portions of the rear covers 600 and 700 may be visible from the outside.

According to various embodiments, when the second housing 220 slides in a first direction, the display area 230-1 of the rollable display 230 may increase and the rear covers 600 and 700 may be exposed to the outside. The printed circuit board disposed in the second housing 220 may not be visible from the outside due to the rear covers 600 and 700 disposed in the second housing 220. Even if the printed circuit board disposed in the second housing 220 protrudes from the first housing 210 according to the sliding of the second housing 220, the printed circuit board may be blocked off from the outside by the rear covers 600 and 700. Accordingly, even if the second housing 220 slides, foreign substances may not directly flow to the printed circuit board from the outside.

According to various embodiments, the rear covers 600 and 700 may be formed of a stiff material, thereby assisting the strength of the second housing 220. For example, the rear covers 600 and 700 may be formed of a high-stiffness polymer material or a metal material. In some embodiments, the rear covers 600 and 700 may be formed of a material different from that of the second housing 220. As the high-stiffness rear covers 600 and 700 are coupled to the second housing 220, the strength of the second housing 220 may be reinforced. For example, if the plate-shaped rear covers 600 and 700 are coupled to the second housing 220, torsional stiffness of the assembly of the rear covers 600 and 700 and the second housing 220 may be improved.

Referring to FIGS. 7 and 8, the rear cover 600 of the first embodiment and the rear cover 700 of the second embodiment may have different lengths in a first direction (e.g., the Y direction in FIGS. 7 and 8). For example, a first direction length W2 of the rear cover 700 included in the electronic device 400 of the second embodiment may be less than a first direction length W1 of the rear cover 600 included in the electronic device 300 of the first embodiment.

The rear cover 700 of the second embodiment may be provided so as not to face a battery (e.g., the battery 900 in FIG. 10) of the electronic device 400. In addition, the rear cover 700 of the second embodiment may be formed so as not to face the driving motor 1100 of the electronic device 400.

Referring to FIGS. 7 and 8, in the case of the first embodiment, there may not be a space between the rear cover 600 and the rollable display 230 when the electronic device 300 is in a full slide-in state. For example, the rollable display 230 and the rear cover 600 may partially overlap each other in a third direction (e.g., the Z direction in FIG. 7). On the other hand, in the case of the second embodiment shown in FIG. 8, the rear cover 700 and the rollable display 230 may be separated from each other when the electronic device 400 is in a full slide-in state. An expansion space (e.g., the expansion space A in FIG. 10) may be provided between the rear cover 700 and the rollable display 230. In other words, the rear cover 700 and the rollable display 230 may not overlap each other in the third direction.

Compared to the electronic device 300 of the first embodiment, the electronic device 400 of the second embodiment may secure a larger battery size using the expansion space. In addition, the expansion space may be used to dispose a driving motor having a larger diameter. For example, a portion of the expansion space may be used for increasing the size of the battery and a portion of the expansion space may be used for increasing the diameter for the driving motor. Of course, it is alternatively possible that the expansion space is only used for the larger battery or for the driving motor with increased diameter. In some embodiments, the expansion space may enable to secure a space in which electric components or structures may be disposed.

FIG. 9 is a cross-sectional view of the electronic device according to the first embodiment cut along a sliding direction. FIG. 10 is a cross-sectional view of the electronic device according to the second embodiment cut along a sliding direction. FIG. 11 is a cross-sectional view of the electronic device according to the first embodiment cut along a sliding direction so that a driving motor is visible. FIG. 12 is a cross-sectional view of the electronic device according to the second embodiment cut along the sliding direction so that the driving motor is visible.

According to various embodiments, the length in a first direction (e.g., the Y direction in FIGS. 9 and 10) and the length in a third direction (e.g., the Z direction in FIGS. 9 and 10) of the electronic device 300 of the first embodiment and the electronic device 400 of the second embodiment may be substantially the same.

Referring to FIG. 9, in the first embodiment, the rear cover 600 may be formed to face the accommodation area 230-2 of the rollable display 230. The cover glass member 213 disposed in the rear cover 600 may also face the accommodation area 230-2. In the first embodiment, the rear cover 600 and the cover glass member 213 may overlap the accommodation area 230-2 in the third direction (e.g., the Z direction in FIG. 9). One surface of the first housing 210 may be a surface facing the battery 800, and the opposite surface of the first housing 210 may be a surface facing the rear cover 223. A battery 800 may be accommodated in a support bracket 225 disposed to cover the battery 800. The support bracket 225 may be disposed between the display area 230-1 and the accommodation area 230-2 when the electronic device 300 is in a slide-in state.

Referring to FIG. 10, in the second embodiment, the rear cover 700 may be formed to not face the accommodation area 230-2 of the rollable display 230. The cover glass member 213 disposed in the rear cover 700 may not face either the accommodation area 230-2. In the second embodiment, the rear cover 700 and the cover glass member 213 may not overlap the accommodation area 230-2 in the third direction (e.g., the Z direction in FIG. 9). In some embodiments, the rear cover 700 and the cover glass member 213 may extend to an end portion of the accommodation area 230-2 of the rollable display 230. One surface of the first housing 210 may be a surface facing the battery 900, and the opposite surface of the first housing 210 may be a surface facing the rear cover 223. A battery 900 may be accommodated in a support bracket 225 disposed to cover the battery 900. The support bracket 225 may be disposed between the display area 230-1 and the accommodation area 230-2 when the electronic device 300 is in a slide-in state.

According to various embodiments, as shown in FIGS. 9 and 10, the batteries 800 and 900 may be disposed in the display area 230-1 and the accommodation area 230-2 of the rollable display 230 when the electronic devices 300 and 400 are in the slide-in state. In the case of a slidable electronic device, the size and disposed location of an internal component such as the battery 800 or 900 may be designed based on the full slide-in state of the electronic device 300 or 400 as shown in FIGS. 9 and 10. Accordingly, the sizes of the batteries 800 and 900 may also be determined based on the space in the full slide-in state of the electronic devices 300 and 400.

Referring to FIGS. 9 and 10, a first distance L1, which is a separation distance between the rear cover 600 or 700 and the display area 230-1 of the rollable display 230 in the third direction (e.g., the Z direction in FIGS. 9 and 10) perpendicular to the sliding direction (e.g., the Y direction in FIGS. 9 and 10) of the electronic device 300 or 400, may be less than a second distance L2, which is a separation distance between one surface of the first housing 210 and the display area 230-1 of the rollable display 230 in the third direction. Since the rear covers 600 and 700 are elements configured to be received inside the first housing 210, in the slide-in state, the first distance L1 between the rear cover 600 or 700 and the display area 230-1 may be less than the second distance L2 between the first housing 210 and the display area 230-1.

The batteries 800 and 900 may be disposed between the display area 230-1 and the accommodation area 230-2. The accommodation area 230-2 and the length of the battery 800 or 900 in the third direction (hereinafter referred to as a “height of the battery”) L_C or L_D may increase as the distance L_A or L_B between the display area 230-1 and the accommodation area 230-2 is secured. In order to reduce the stress applied to the rollable display 230, the accommodation area 230-2 may be substantially flat in the first direction. For example, a guide rail (e.g., the guide rail 226 in FIG. 4) by which a support member 240 supporting the rollable display 230 is guided may have a portion corresponding to the accommodation area 230-2 and formed substantially parallel to the first direction. Accordingly, the distance L_A or L_B between the display area 230-1 and the accommodation area 230-2 may be determined by the distance between the structure facing the accommodation area 230-2 and the display area 230-1.

In the first embodiment, since the rear cover 600 extends to the location facing the rollable display 230, the accommodation area 230-2 of the rollable display 230 may face the rear cover 600. In the second embodiment, since the rear cover 700 does not face the rollable display 230, the accommodation area 230-2 of the rollable display 230 may face one surface of the first housing 210, instead of the rear cover 600. As described above, the first distance L1 between the rear cover 600 or 700 and the display area 230-1 may be less than the second distance L2 between the first housing 210 and the display area 230-1. Accordingly, the distance L_B between the display area 230-1 and the accommodation area 230-2 in the second embodiment may be greater than the distance L_A between the display area 230-1 and the accommodation area 230-2 in the first embodiment. Compared to the first embodiment, the second embodiment may secure a larger distance between the display area 230-1 and the accommodation area 230-2 (L_A<L_B).

The heights L_C and L_D of the batteries 800 and 900 may be summarized as follows. The heights L_C and L_D of the batteries 800 and 900 disposed between the display area 230-1 and the accommodation area 230-2 may be determined by the distances L_A and L_B between the display area 230-1 and the accommodation area 230-2. The distances L_A and L_B between the display area 230-1 and the accommodation area 230-2 may be determined according to the distance between the structure facing the accommodation area 230-2 and the display area 230-1. In the case of the second embodiment, the accommodation area 230-2 may face one surface of the first housing 210, instead of facing the rear cover 700. In the case of the first embodiment, the accommodation area 230-2 may face the rear cover 600. The second distance L2, which is the distance between the first housing 210 and the display area 230-1, is greater than the first distance L1, which is the distance between the rear covers 600 and 700 and the display area 230-1. Accordingly, in the case of the second embodiment, since the distance between the display area 230-1 and the accommodation area 230-2 may be secured more than in the first embodiment (L_A<L_B), the height L_D of the battery 900 in the second embodiment may be greater than the height L_C of the battery 800 in the first embodiment. The capacities of the batteries 800 and 900 may be proportional to the volumes of the batteries 800 and 900. If the batteries 800 and 900 have the same first direction length, the capacities of the batteries 800 and 900 may be determined according to the heights L_C and L_D of the batteries 800 and 900. Since the structure of the second embodiment may enable disposition of the battery 900 having a higher height, compared to the structure of the first embodiment, the battery 900 having a capacity greater than the battery 800 of the first embodiment may be disposed (L_C<L_D).

In various embodiments, a bending area 230-3 of the rollable display 230 may be an area that connects the accommodation area 230-2 and the display area 230-1 and is to be bent. The curvature radius of the bending area 230-3 may vary depending on the distance L_A or L_B between the accommodation area 230-2 and the display area 230-1. The smaller the distance L_A or L_B between the accommodation area 230-2 and the display area 230-1, the curvature radius may be smaller. If the curvature radius is reduced, deformation stress applied to the rollable display 230 may increase, thereby lowering the durability of the rollable display 230. In the case of the second embodiment, a greater distance between the accommodation area 230-2 and the display area 230-1 may be secured compared to the first embodiment (L_A<L_B). Accordingly, the curvature radius of the rollable display 230 in the second embodiment may be greater than the curvature radius of the rollable display 230 in the first embodiment.

In the case of the second embodiment, compared to the first embodiment, the distance L_B between the accommodation area 230-2 and the display area 230-1 may be further secured by a difference between the second distance L2, which is a distance between the display area 230-1 and the first housing 210, and the first distance L1, which is a distance between the display area 230-1 and the rear cover 700. In the second embodiment, a repellant force of the rollable display 230 may be reduced by increasing the curvature radius of the rollable display 230 by securing the distance L_B between the accommodation area 230-2 and the display area 230-1, thereby reducing the stress of the rollable display 230 applied in the bending area 230-3. Accordingly, the durability of the rollable display 230 may be improved.

According to various embodiments, in the second embodiment, the maximum length of the display area 230-1 of the rollable display 230 (the length of the display area 230-1 in the Y-axis direction when the first housing 210 fully slides relative to the second housing 220) may be determined according to the overlapping portion of the first housing 210 and the second housing 220 (e.g., the overlapping portion 910 in FIG. 10). The first housing 210 may slide relative to the second housing 220 in the Y-axis direction, based on FIG. 10, by the length of the overlapping portion 910. If the second housing 220 slides relative to the first housing 210 beyond the overlapping portion 910, the inside between the first housing 210 and the second housing 220 may be visible from the outside. Accordingly, the maximum length of the display area 230-1 of the rollable display 230 may be determined by the length of the overlapping portion 910 of the first housing 210 and the second housing 220.

Referring to FIGS. 11 and 12, driving motors 1000 and 1100 may be disposed between the batteries 800 and 900 and the printed circuit board 251. In the first embodiment, the driving motor 1000 may face the rear cover 600. On the other hand, in the second embodiment, the driving motor 1100 may not face the rear cover 700. Accordingly, the second embodiment may secure a more space in the third direction (e.g., the Z direction in FIG. 12) for the driving motor 1100, compared to the first embodiment. The size L6 of the driving motor 1100 of the second embodiment may be greater than the size L5 of the driving motor 1000 of the first embodiment. For example, as shown in FIG. 12, the driving motor 1100 may occupy at least a portion of the expansion space A provided between the rear cover 700 and the rollable display 230. A larger driving motor may have a higher driving force (e.g., torque) thereof. Accordingly, the driving motor 1100 of the second embodiment may have a higher driving force than the driving motor 1000 of the first embodiment.

In some embodiments, similar to the second embodiment, the rear cover 700 may be formed such that the rear cover 700 and the rollable display 230 do not face each other, and an additional battery (not shown) separated from the battery 900 may be disposed in the expansion space A between the rear cover 700 and the rollable display 230.

The additional battery may be electrically connected to the battery 900. In this way, the battery 900 and the additional battery effectively form one (larger) battery. The additional battery may be formed in a shape corresponding to the expansion space A or may be formed in a shape capable of occupying a portion of the expansion space A.

An electronic device (e.g., the electronic device 400 in FIG. 8) according to various embodiments disclosed in this document may include a first housing (e.g., the first housing 210 in FIG. 10), a second housing (e.g., the second housing 220 in FIG. 10) coupled to the first housing so as to slide in a first direction and in a second direction opposite the first direction, a printed circuit board (e.g., the printed circuit board 251 in FIG. 10) disposed in the second housing, a rear cover (e.g., the rear cover 700 in FIG. 8) disposed in the second housing and configured to support the printed circuit board, a rollable display (e.g., the rollable display 230 in FIG. 8) including a display area (e.g., the display area 230-1 in FIG. 10) exposed to the outside of the electronic device, an accommodation area (e.g., the accommodation area 230-2 in FIG. 10) received inside the electronic device, and a bending area (e.g., the bending area 230-3 in FIG. 10) connecting the display area and the accommodation area and configured to be bent, and having a display area that is reduced or expanded based on a sliding-in or sliding-out operation of the second housing, and a battery (e.g., the battery 900 in FIG. 10) disposed in a space provided in the first housing and the second housing, wherein the rear cover may be formed so as not to overlap the accommodation area of the rollable display when the rollable display is viewed vertically when the second housing is in a full slide-in state in the second direction.

In addition, an expansion space A may be provided between the rear cover and the rollable display, and the battery may be configured to occupy the expansion space in a third direction perpendicular to the first and second directions.

In addition, the battery, in a slide-in state, may be disposed in a position not facing the rear cover and disposed between the display area and the accommodation area of the rollable display.

In addition, a first distance corresponding to a distance between the display area of the rollable display and the rear cover in the third direction may be less than a second distance corresponding to a distance between the display area of the rollable display and one surface of the first housing in the third direction.

In addition, the accommodation area of the rollable display may be substantially flat in the first direction and the second direction.

In addition, the accommodation area of the rollable display may be disposed to not face the rear cover so that the accommodation area may be further spaced from the display area by a distance corresponding to a difference between the second distance and the first distance and so that a curvature radius of the bending area may be increased.

In addition, the accommodation area of the rollable display may be disposed between the battery and the first housing.

In addition, the electronic device may further include a support member (e.g., the support member 240 in FIG. 10) configured to support the rollable display to be bendable.

In addition, the electronic device may further include a guide rail (e.g., the guide rail 226 in FIG. 4) configured to guide movement of the support member according to sliding of the second housing.

In addition, the support member may include a plurality of bar-shaped support portions segmented from each other, and both ends of the support portion may be inserted into the guide rail.
