[0003] Due to advancements in information and communication technology and semiconductor technology, various functions are being integrated into a single portable electronic device. For example, electronic devices can implement not only communication functions but also entertainment functions such as games, multimedia functions such as music and video playback, communication and security functions for mobile banking, and functions such as schedule management and electronic wallets. These electronic devices are being modified to allow users to carry them conveniently.

[0004] Flexible displays allow the screen to be flat or curved by rolling, folding, or bending the panel. Flexible displays can be implemented as rollable displays, bendable displays, foldable displays, sliderable displays, etc. Electronic devices containing such flexible displays can be applied not only to mobile devices such as smartphones and tablet PCs but also to TVs, automotive displays, wearable devices, and more, and their application fields are expanding.

[0007] In implementing a rollable electronic device, the housings of the electronic device can move relative to each other (e.g., slide movement), and the flexible display can include a rolling section and a flat section as it enables sliding movement.

[0008] According to various embodiments of the present disclosure, a flexible display can be replaced with a flexible film that can be folded and unfolded on a glass substrate or a high-hardness substrate. Since the film is used as a substrate, there are advantages such as being thin, lightweight, resistant to impact, and foldable. The flexible display has a structure in which a film is laminated onto the display. In particular, as the usage, auxiliary, and manufacturing environments of the flexible display become more diverse and harsh, there is a need for a film that maintains viscoelastic properties over a wide temperature range and possesses excellent recovery properties.

[0009] In implementing a slideable electronic device capable of sliding motion, it is necessary to control the sliding motion according to specific conditions faced by the flexible display.

[0010] Flexible displays can form curved and flat surfaces in rolling and flat sections, and their shape can change frequently while sliding. At this time, the physical properties of the flexible display may be affected by the surrounding environment.

[0011] The slideable electronic device according to the present disclosure needs to have the output of the motor controlled according to specific conditions in order to provide stable sliding operation.

[0012] According to various embodiments of the present disclosure, an electronic device that slides in consideration of the repulsive force of a flexible display can be provided.

[0013] According to various embodiments of the present disclosure, an electronic device including a motor controlled according to specific conditions, such as considering the surrounding environment of an electronic device or a flexible display, can be provided.

The display support member (140) receives elastic force in the opposite direction through an elastic belt (153a) and a spring structure (153c), and wrinkles or crumpling of the display (130) and / or the display support member (140) can be reduced.

[0062] According to various embodiments, the second roller (155) can guide the movement of the elastic belt (153). According to one embodiment, the second roller (155) can be rotatably mounted on the other edge of the base bracket (122). According to one embodiment, the second roller (155) can guide the sliding movement of the elastic belt (153a) while rotating along a rotation axis (e.g., Y-axis).

[0063] According to various embodiments, the electronic device (100) may include a battery (102). The battery (102) may supply power to at least one component of the electronic device (100). According to one embodiment, the battery (102) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell. According to one embodiment, the battery (102) may be placed within a housing (110, 120). For example, the battery (102) may be mounted on a part of the second housing (120) (e.g., a base bracket (122)).

[0064] According to various embodiments, the electronic device (100) may include a printed circuit board (104) equipped with a processor (not shown) or memory (not shown). According to one embodiment, the printed circuit board (104) may be placed within a housing (110, 120). For example, the printed circuit board (120) may be placed between a base bracket (122) and a rear plate (124).

[0065] The processor can, for example, execute software (e.g., a program) to control at least one other component (e.g., a hardware or software component) of an electronic device (100) connected to the processor and perform various data processing or operations. According to one embodiment, the processor may include a main processor (e.g., a central processing unit or an application processor) or an auxiliary processor (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can be operated independently or together with it.

[0066] The memory can store various data used by at least one component (e.g., a processor) of the electronic device (100). The memory may include volatile memory or non-volatile memory.

[0068] FIGS. 5A and 5B are side views showing the closed and open states of a slideable electronic device according to various embodiments of the present disclosure.

[0069] Referring to FIGS. 5a and 5b, the electronic device (100) may include a first housing (110), a second housing (120), a flexible display (500), a roller (e.g., a first roller (151) or a second roller (155)), and a display support member (140) for supporting at least a portion of the flexible display (500). The configuration of the first housing (110), the second housing (120), and the display support member (140) may be all or partly the same as the configuration of FIGS. 1 and 2.

[0070] According to various embodiments, a motor (e.g., the motor (1301) of FIG. 13) can rotate a roller (e.g., the first roller (151) or the second roller (155)) to move a flexible display (500).

[0071] According to various embodiments, the flexible display (500) can be replaced with a flexible film that can be folded and unfolded on a glass substrate or a high-hardness substrate. Since the film is used as a substrate, it has the advantages of being thin, light, resistant to impact, and foldable. The flexible display may have a structure in which the film is laminated onto the display. The film may have physical properties that maintain viscoelastic properties over a wide temperature range and have recovery properties.

[0072] According to various embodiments, the flexible display (500) may include a first display area (510) and a second display area (520). For a description of the first display area (510) and the second display area (520), refer to the contents of FIGS. 1 to 4.

[0073] According to various embodiments, the second display area (A2) may include a second-1 area (521) and a second-2 area (522).

[0074] According to various embodiments, the second-1 region (521) is a flexible display (500) that forms a curved surface by a roller (e.g., the first roller (151) or the second roller (155)), and when the flexible display (500) is moved from a closed state (501) to an open state (502) by a motor (e.g., the motor (1301) of FIG. 13), the second-1 region (521) may be located where the first display region (510) was. For the closed state (e.g., FIG. 5a) and the open state (e.g., FIG. 5b), refer to the descriptions in FIG. 1 through 4.

[0075] According to various embodiments, in a closed state (e.g., FIG. 5a), the 2-1 region (521) forms a curved surface and the 2-2 region (522) forms a flat surface in the closed state of the first housing (110) relative to the second housing (120), and in an open state (e.g., FIG. 5b), the 2-1 region (521) forms a flat surface and the 2-2 region (522) forms a curved surface in the open state of the first housing (110) relative to the second housing (120).

[0076] According to various embodiments, the 2-1 region (521) forms a curved surface in a closed state (e.g., FIG. 5a) and forms a flat surface as it moves to an open state (e.g., FIG. 5b). The 2-2 region (522) forms a flat surface in a closed state (e.g., FIG. 5a) and forms a curved surface as it moves to an open state (e.g., FIG. 5b).

[0077] According to various embodiments, the shape of the second-1 region (521) may change from a flat surface to a curved surface or vice versa as it moves from a closed state (e.g., FIG. 5a) and an open state (e.g., FIG. 5b). For example, a repulsive force (601) may be applied to the second-1 region (521) due to the change in shape of the second-1 region (521). For example, a greater repulsive force may be applied to the second-1 region (521) when the shape of the second-1 region (521) changes from a flat surface to a curved surface than when it changes from a curved surface to a flat surface.

[0078] FIG. 6 is a side view illustrating the lifting of a flexible display of a slideable electronic device according to various embodiments of the present disclosure.

[0079] According to various embodiments, the electronic device (100) includes a first housing (110), a second housing (120), a display (130), a display support member (140) for supporting at least a portion of the display (130), a roller (e.g., a first roller (151) or a second roller (155)), and a flexible display (500), and the configurations may be described with reference to the descriptions in FIGS. 1 to 5.

[0080] According to various embodiments, the flexible display (500) includes a first display area (510) and a second display area (520), and the second display area (520) includes a second-1 area (521) and a second-2 area (522). The configurations may be described with reference to the description in FIG. 5.

[0081] According to various embodiments, the display support member (140) may include a plurality of bars (141) or rods. For example, as the first housing (110) slides, a portion of the display support member (140) facing the first roller (151) may form a curved surface. For example, a second-1 region (521) of the flexible display (500) is mounted or supported on the display support member (140), and a portion of the second-1 region (521) may be retracted into the interior of the second housing (120) to enter a closed state (e.g., FIG. 5a). A portion of the second-1 region (521) may form a substantially flat surface and then form a curved surface as it enters the closed state (e.g., FIG. 5a).

[0082] According to various embodiments, when the flexible display (500) forms a flat surface and then forms a curved surface, lifting (601) may occur due to a repulsive force attempting to return to its original flat state. According to another embodiment, when the flexible display (500) forms a flat surface and then forms a curved surface, a recovery force (not shown) attempting to restore the original shape may occur. For example, as the display support member (140) moves to position the second-1 region (521) inward, a gap may be formed between the display support member (140) and the display support member (140) due to the repulsive force. For example, near where a part of the display support member (140) forms a curved surface, the second-1 region (521) bends less than the first roller (151) due to a repulsive force attempting to maintain a flat surface. Depending on the physical properties of the flexible display (500), the repulsive force may become stronger or decrease under specific conditions.

[0083] Lifting (601) due to repulsion causes deformation of the flexible display (500), so the sliding movement of the flexible display (500) may not be smooth, and problems with the quality and stability of the display may occur when it comes into contact with a user, such as a touch panel. Therefore, it is necessary to minimize the degree of deformation of the flexible display (500) due to repulsion.

[0084] According to various embodiments, the motor (e.g., the motor (1301) of FIG. 13) may control the output to prevent smooth movement from being reduced by the repulsive force of the flexible display (500). According to another embodiment, since strong motor control in a state where the repulsive force of the flexible display (500) is exerted can increase the stress on the flexible display (500), the output of the motor may be controlled for stability.

[0085] FIG. 7 is a drawing for explaining the difference in repulsive force according to the operation of a slideable electronic device according to various embodiments of the present disclosure.

[0086] Referring to Fig. 7, This is a graph (701) measuring the repulsive force when moving from an open state (e.g., Fig. 5b) to a closed state (e.g., Fig. 5a), and a graph (702) measuring the case of moving from a closed state (e.g., Fig. 5a) to an open state (e.g., Fig. 5b).

[0087] According to various embodiments, when comparing the repulsive force measured in a constant temperature environment for the second-1 region (521), the repulsive force when moving from an open state (e.g., FIG. 5b) to a closed state (e.g., FIG. 5a) (e.g., Open to Close (701) in FIG. 7) may be greater than when moving in the opposite direction (e.g., Close to Open (702) in FIG. 7). In other words, it can be seen that when the shape of the second-1 region (521) changes from a flat surface to a curved surface (e.g., Open to Close (701) in FIG. 7) is greater than when the shape of the second-1 region (521) changes from a curved surface to a flat surface (e.g., Close to Open (702) in FIG. 7).

[0088] According to various embodiments, when measuring the repulsive force for the second-2 region (522) in a constant temperature environment, the repulsive force when moving from an open state (e.g., FIG. 5b) to a closed state (e.g., FIG. 5a) may be smaller than when moving in the opposite direction. In other words, the repulsive force when the shape of the second-2 region (522) changes from a curved surface to a flat surface may be smaller than when the shape of the second-2 region (522) changes from a flat surface to a curved surface.

[0089] According to various embodiments, the temperature around the 2-1 region (521) or the 2-2 region (522) can be measured with reference to FIG. 7 to compare the case at room temperature with the case at low temperature. With reference to the graphs (701, 702) of FIG. 7, the repulsive force at room temperature may be smaller than the repulsive force at low temperature.

[0090] For example, when moving from an open state (e.g., Fig. 5b) to a closed state (e.g., Fig. 5a) as in 701 of Fig. 7 (e.g., Open to Close (701) of Fig. 7), a lower repulsive force may be applied when the temperature around the 2-1 region (521) is at room temperature compared to when it is at a low temperature. Similarly, when moving from an open state (e.g., Fig. 5b) to a closed state (e.g., Fig. 5a) (e.g., Open to Close (701) of Fig. 7), a lower repulsive force may be applied when the temperature around the 2-2 region (522) is at room temperature compared to when it is at a low temperature.

[0091] For example, when moving from a closed state (e.g., FIG. 5a) to an open state (e.g., FIG. 5b) as in 702 of FIG. 7 (e.g., Close to Open (702) of FIG. 7), a lower repulsive force may be applied when the temperature around the 2-1 region (521) is at room temperature than when it is at low temperature. Similarly, when moving from a closed state (e.g., FIG. 5a) to an open state (e.g., FIG. 5b) (e.g., Close to Open (702) of FIG. 7), if the repulsive force acting on the 2-2 region (522) is measured at room temperature and when measured at low temperature, the repulsive force at low temperature may be greater than at room temperature. FIG. 8 is a diagram illustrating the difference in repulsive force according to the operation of a slideable electronic device according to various embodiments of the present disclosure.

[0092] The x-axis can represent temperature, and the y-axis can represent repulsive force. According to various embodiments, it can be observed that the repulsive force increases as the temperature decreases in each range starting from room temperature. The unit of the repulsive force is not specifically defined and can be expressed as a relative value between 3 and 5. Referring to Fig. 8, it can be seen that a greater repulsive force may be present in the lower temperature range. In this regard, by referring to Table 1 below, the degree of increase in repulsive force by temperature can be identified, and since the motor must be adjusted accordingly, the degree of repulsive force can be checked and quantified in advance.

[0093] For example, Table 1 can be divided into temperature ranges of room temperature, 0 degrees, -5 degrees, and -10 degrees at intervals of approximately 5 degrees. Assuming room temperature is 0 degrees or higher, the magnitude of the repulsive force (unit omitted) in a specific area of ​​the flexible display (500) of the electronic device (100) can be compared for each range. To compare the magnitude of the repulsive force in Table 1, only the temperature conditions can be varied, while the specific area of ​​the flexible display (500), the change in shape, and the duration of the state maintenance can be kept the same. As a result, it can be seen that the difference in repulsive force is approximately 3.11 at room temperature, and increases to approximately 4.08, 4.52, and 5.07 as it decreases at intervals of approximately -5 degrees. In Table 1, the repulsive force increases gradually by dividing the ranges, but the repulsive force can also increase continuously with a continuous decrease in temperature.

[0094] By smartphone temperature repulsive force room temperature 3.11 0 degrees 4.08 -5 degrees 4.52 -10 degrees 5.07

[0095] FIGS. 9a, 9b, and 9c are drawings illustrating the sliding movement of each region of a flexible display in a slideable electronic device according to various embodiments of the present disclosure.

[0096] According to various embodiments, the flexible display (500) includes a first display area (510) and a second display area (520), and the second display area includes a second-1 area (521) and a second-2 area (522), and reference can be made to the description of FIG. 5.

[0097] According to various embodiments, regarding the control of the motor output when the flexible display (500) enters a curved section depending on the closed state (e.g., FIG. 5a) and the open state (e.g., FIG. 5b), one may refer to the description in FIG. 5a and FIG. 5b. Regarding the magnitude of the repulsive force (600) according to the temperature range of the flexible display (500), one may refer to the description in FIG. 7 and FIG. 8. Regarding the description of the repulsive force (601) of the flexible display (500), one may refer to FIG. 6.

[0098] According to various embodiments, the temperature of each region of the flexible display (500) can be sensed, and when the region enters a curved section, the output of the motor according to the temperature can be controlled.

[0099] According to various embodiments, when the output of the motor is to be controlled according to temperature as the flexible display (500) moves from an open state (e.g., FIG. 9c) to a closed state (e.g., FIG. 9a), the point to measure the reference temperature may be a point in the area of ​​the flexible display (500) that enters the curved section.

[0100] According to various embodiments, when the flexible display (500) moves from a closed state (e.g., FIG. 5a) to an open state (e.g., FIG. 5b) and the second-1 region forming a curved surface forms a flat surface, the temperature can be measured based on point 2 of FIG. 9b and point 3 of FIG. 9c, and the motor can be driven based on the measured temperature. When the flexible display (500) moves from an open state (e.g., FIG. 5b) to a closed state (e.g., FIG. 5a) and the second-1 region forming a flat surface forms a curved surface, the temperature can be measured based on points 1 and 2 of FIG. 9b, and the motor can be driven based on the measured temperature.

[0101] According to various embodiments, when the flexible display (500) moves from a closed state (e.g., FIG. 5a) to an open state (e.g., FIG. 5b) and the second-2 region forming a flat surface becomes a curved surface, the temperature can be measured based on points 3 and 4 of FIG. 9c, and the motor can be driven based on the measured temperature. According to various embodiments, when the flexible display (500) moves from an open state (e.g., FIG. 5b) to a closed state (e.g., FIG. 5a) and the second-2 region forming a curved surface becomes a flat surface, the temperature can be measured based on point 2 of FIG. 9b and point 3 of FIG. 9c, and the motor can be driven based on the measured temperature. In other words, when each region enters a curved section, the output of the motor can be adjusted using a thermistor adjacent to that region.

[0102] FIG. 10 is a diagram illustrating the difference in repulsive force at different state maintenance times according to embodiments of the present disclosure.

[0103] FIG. 11 is a drawing illustrating different motor outputs during a single state holding time according to one embodiment of the present disclosure.

[0104] FIG. 12 is a diagram comparing the output of a motor according to various embodiments of the present disclosure.

[0105] According to various embodiments, the flexible display (500) includes a first display area (510) and a second display area (520), and the second display area includes a second-1 area (521) and a second-2 area (522), and reference can be made to the description of FIG. 5.

[0106] According to various embodiments, regarding the control of the motor output when the flexible display (500) enters a curved section depending on the closed state (e.g., FIG. 5a) and the open state (e.g., FIG. 5b), the description in FIG. 5a and FIG. 5b may be referenced. The magnitude of the repulsive force according to the temperature range of the flexible display (500) may be referenced in FIG. 7 and FIG. 6 may be referenced for an explanation of the repulsive force of the flexible display (500).

[0107] According to various embodiments, the flexible display (500) may remain stationary at one point while moving between a closed state (e.g., FIG. 5a) and an open state (e.g., FIG. 5b). If the time maintained in the stationary state is set as the x-axis and the repulsive force as the y-axis, it can be seen that as the time maintained in the stationary state increases, the repulsive force increases and converges to a constant value. Conversely to the repulsive force, the recovery force may gradually decrease as the time maintained in the stationary state increases, as it becomes more difficult to recover. Referring to FIG. 10, as the time the flexible display (500) remains stationary increases, the repulsive force (601) may gradually increase and then converge to a certain level. For example, as the time at least one surface of the flexible display (500) remains in a flat or curved state increases, the repulsive force may gradually increase.

[0108] For example, the second-1 region (521) forms a plane in an open state (e.g., FIG. 5b), and the magnitude of the repulsive force acting on the second-1 region (521) can be compared when the plane is maintained for about 30 minutes and when it is maintained for about 2 hours. When the flexible display (500) moves to a closed state (e.g., FIG. 5a), less repulsive force may be applied to the second-1 region (521) when the flexible display (500) is left for about 30 minutes than when it is left for about 2 hours.

[0109] For example, the second-2 region (522) forms a plane in an open state (e.g., FIG. 5b), and the magnitude of the repulsive force acting on the second-2 region (522) can be compared when the plane is maintained for about 30 minutes and when it is maintained for about 2 hours. When the flexible display (500) moves to a closed state (e.g., FIG. 5a), less repulsive force may be applied to the second-2 region (522) when the flexible display (500) is left for about 30 minutes than when it is left for about 2 hours.

[0110] Referring to FIG. 10, the repulsive force (601) and the recovery force can be expressed as relative values ​​without defining specific units.

[0111] Referring to Table 2 below, in a closed state (e.g., FIG. 5a), the second-2 region (522) forms a flat surface, and the time for maintaining the flat surface can be set to approximately 10 minutes, 30 minutes, 1 hour, or 2 hours. For example, if the second-2 region (522) moves to an open state (e.g., FIG. 5b) to form a curved surface while the second-2 region (522) forms a flat surface for approximately 10 minutes, the recovery force (not shown) on the second-2 region (522) may be approximately 25%. The unit of the recovery force (not shown) may be omitted and can be understood as a relative value. If the second-2 region (522) moves to an open state (e.g., FIG. 5b) to form a curved surface while the second-2 region (522) forms a flat surface for approximately 2 hours, the recovery force (not shown) on the second-2 region (522) may be approximately 100%. For example, if the second-2 region (522) that is to form a curved surface is maintained in a flat state for about 2 hours, the second-2 region (522) is difficult to form a curved surface, and a recovery force (not shown) attempting to form a flat surface may be exerted significantly. For example, regarding a region that forms a flat surface while the flexible display (500) moves between a closed state (e.g., FIG. 5a) and an open state (e.g., FIG. 5b), the recovery force may increase significantly with each increase in the maintenance time of the state up to about 1 hour. When the maintenance time of the state is about 1 hour or more, it can be observed that the increase in the recovery force decreases.

[0112] Flat time (closed time) Resilience 10 minutes 25% 30 minutes 70% 1 hour 90% 2 hours 100%

[0113] According to various embodiments, the flexible display (500) can control the output of the motor according to the working state holding time (idle time) by counting the working state holding time in a closed state (e.g., FIG. 5a) and an open state (e.g., FIG. 5b). As the working state holding time increases, the repulsive force (601) increases, so the output can be increased to maintain a constant speed at which the flexible display (500) slides.

[0114] Referring to FIG. 11, it can be seen that the output growth rate is greater in the range where the work state maintenance time along the x-axis is within approximately 1 hour than in the case where the work state maintenance time is 1 hour or more. For example, it can be seen that when the work state maintenance time is approximately 2 hours or more, the repulsion force (601) and recovery force converge to a constant value.

[0115] Referring to Table 3, the output level according to the working state maintenance time can be verified. For example, when the motor output was measured while gradually increasing the idle time (working state maintenance time) at intervals of approximately 5 minutes,

[0116] Referring to Table 2, it can be seen that the recovery rate is about 25% in the interval where the idle time (day state maintenance time) is about 10 minutes, and about 90% in the case where the idle time (day state maintenance time) is about 1 hour.

[0117] According to various embodiments, as the recovery force increases, the force that the flexible display (500) attempts to return to its original shape increases, so the output of the motor can be increased so that the flexible display (500) naturally slides by the roller while forming a curved surface. Therefore, it can be confirmed that as the recovery force increases, the output of the motor can also increase.

[0118] For example, in Table 3, it can be seen that the motor output gradually increases by about 10% to 5% as the idle time increases at intervals of about 5 minutes. The rate of increase in motor output can be controlled by considering the rate of increase in recovery power with increasing idle time. For example, in Table 3, if the motor output is controlled to about 99% when the idle time is about 2 hours or more, the motor output can be controlled to 50% when the idle time is about 5 minutes or less.

[0119] Neglect time Motor output (duty) Less than 5 minutes 50% 5 minutes 60% 10 minutes 70% 20 minutes 80% 30 minutes 90% 1 hour 95% 2 hours 99%

[0121] According to various embodiments, the output of the motor can be controlled by comprehensively considering various environments in which the flexible display (500) is placed. Refer to FIGS. 5 to 7 for an explanation of the repulsive force according to the shape change of the flexible display (500). Refer to FIGS. 7 to 9 for an explanation of the repulsive force according to the temperature of the flexible display (500). Refer to FIGS. 10 to 12 for an explanation of the repulsive force according to the one-state maintenance time of the flexible display (500).

[0122] According to various embodiments, the repulsive force of the flexible display (500) can comprehensively consider various environments in which the flexible display (500) is placed. It can be seen that the output of the repulsive force (601) of the flexible display (500) can be determined according to at least one of the shape change of the flexible display (500), the temperature of the flexible display, and the time of maintaining the flexible display (500) in a single state.

[0123] Referring to Table 4, the time spent in a working state (idle time) between an open state (e.g., FIG. 5b) or a closed state (e.g., FIG. 5a) can be divided into 5-minute intervals. A motor (e.g., the motor (1301) in FIG. 13) can rotate a roller to move the flexible display (500), and the range can be divided into 1 to 4 sections based on the rotation angle. For example, based on a specific area of ​​the flexible display (500), the state immediately before entering the roller can be designated as section 1, and the section forming a curved surface by the rotation of the roller can be designated as sections 2 to 4, with the range divided according to the rotation angle of the roller. It can be observed that as the working state maintenance time increases in section 1 among sections 1 to 4, the motor output (motor duty) gradually increases. Additionally, it can be seen that when moving from section 1 to section 4 while maintaining the same working state maintenance time, the repulsive force gradually increases.

[0124] For example, when the second-1 region (521) of the flexible display (500) moves from an open state (e.g., FIG. 5b) to a closed state (e.g., FIG. 5a), the time for forming a flat surface in the open state (e.g., FIG. 5b) can be counted. When the maintenance time for forming a flat surface is between about 5 minutes and 10 minutes, the second-1 region (521) can enter a curved section by the roller by operating the motor so that it becomes a closed state (e.g., FIG. 5a). The roller can move the second-1 region (521) while rotating from the open state (e.g., FIG. 5b) to the closed state (e.g., FIG. 5a). The first section in which the second-1 region (521) forms a curved surface may refer to a range of rotation angles of the roller (about 45 degrees or more) for the second-1 region (521) to move while forming a flat surface and then enter a curved section by the roller. Section 2 is a section where the roller rotates further from Section 1 at an angle between approximately 15 and 45 degrees, causing Section 2-1 (521) to form a more curved surface, Section 3 is a section where a significant portion of Section 2-1 (521) forms a curved surface at an angle between approximately 0 and 15 degrees, and Section 4 is a section where a significant portion of Section 2-1 (521) forms a curved surface at an angle of less than approximately 0 degrees. It can be seen that as Section 2-1 (521) forms a curved surface according to the rotation of the roller from Section 1 to Section 4, the output of the motor also increased from approximately 53% to approximately 78%.

[0126] According to various embodiments, when at least one of the following applies—when the shape of at least a portion of the second display area changes from a flat surface to a curved surface, when the temperature of the flexible display is below a specific temperature, and when the one-state maintenance time of the flexible display is above a specific time—the output may be continuously increased.

[0127] Referring to FIG. 12, the x-axis represents the case where the shape of at least a portion of the second display area changes from a flat surface to a curved surface as the roller rotates from a closed state (e.g., FIG. 5a) to an open state (e.g., FIG. 5b), and the magnitude of the repulsive force (601) can be compared according to temperature. When the working state maintenance time is kept the same at less than 5 minutes, it can be seen that when plotted according to temperature, the repulsive force shows a value between 50% and 60% at room temperature, whereas the repulsive force shows a value between 65% and 90% at low temperature. If the temperature is maintained at room temperature, when plotted according to the working state maintenance time, it can be seen that the repulsive force is about 25% higher when the working state maintenance time is 25 minutes compared to when the working state maintenance time is 5 minutes.

[0128] FIG. 13 is a drawing illustrating a motor and a drive rail in an electronic device of the present disclosure.

[0129] According to various embodiments, the electronic device (100) may include a first housing (110), a second housing (120), a display (130), and a display support member (140) for supporting at least a portion of the display (130). The configuration of the first housing (110), the second housing (120), the display (130), and the display support member (140) may be all or partly the same as the configuration of the first housing (110), the second housing (120), and the display (130) of FIGS. 1 and 2. First housing (110), second housing (120), flexible display (500) , The roller (e.g., first roller (151) or second roller (155)) and the support member (140) may refer to the contents of FIGS. 1 to 5.

[0130] According to various embodiments, a motor (e.g., the motor (1301) of FIG. 13) can rotate a roller (e.g., the first roller (151) or the second roller (155)) to move a flexible display (500).

[0131] For example, referring to FIG. 13, the output resulting from the rotation of the rotor can be controlled by adjusting the duty cycle (Vref duty) of the reference voltage in each phase A / B of the motor (e.g., the motor (1301) of FIG. 13) of the step motor driver IC (step motor driver integrated circuit). The output of the motor (e.g., the motor (1301) of FIG. 13) can be controlled such that when the duty cycle of the reference voltage (Vref) increases, the average current (Iavg) increases and the magnetic field of the stator phase increases, thereby increasing the rotational speed (output) of the rotor. Therefore, the duty cycle of the motor (e.g., the motor (1301) of FIG. 13) can be described as the duty-on period when the reference voltage (Vref) is applied and the duty-off period when the reference voltage (Vref) is 0.

[0132] According to various embodiments, when the flexible display (500) slides and enters a curved section, a repulsive force (601) may be applied to the flexible display (500). Refer to FIG. 6 for an explanation of the repulsive force (601). In order to prevent the slide movement of the flexible display (500) from being reduced due to the repulsive force, the output of the motor (e.g., the motor (1301) of FIG. 13) may be increased to maintain a constant movement speed. Alternatively, the output of the motor (e.g., the motor (1301) of FIG. 13) may be adjusted appropriately to prevent excessive stress from being applied to the flexible display (500).

[0133] According to the present disclosure, in an electronic device (100), the output of the motor can be adjusted to provide a flexible display (500) that slides at a constant speed to the user, and there is an advantage that the stability of the flexible display (500) can be increased.

[0134] It will be obvious to those skilled in the art that the electronic device including the display support member of the present disclosure described above is not limited by the aforementioned embodiments and drawings, and that various substitutions, modifications, and changes are possible within the technical scope of the present disclosure.
