[0078] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0079] The display device provided in this application can be applied to various electronic devices capable of displaying information. Under different usage conditions, users can unfold and retract the display device to adjust the display area and meet different needs. For example, when a user needs to view videos, make video calls, or browse large amounts of information, the display device can be unfolded to increase the display area and provide a better visual experience; when a user does not need a large screen, the display device can be retracted to reduce its size, making it convenient to carry and store. In practical applications, this display device can be used in any product or component with display and scrolling functions, such as mobile phones, tablets, televisions, monitors, laptops, digital photo frames, and smartwatches. The following embodiments will use a smartwatch as an example to describe in detail the structure of the display device in a smartwatch.

[0080] Please refer to Figures 1, 2, 3, and 4. Figure 1 is a diagram showing the storage effect of a flexible display panel in a display device according to an embodiment of this application. Figure 2 is a diagram showing the unfolded effect of a flexible display panel in a display device according to an embodiment of this application. Figure 3 is an exploded view of the display device shown in Figure 1. Figure 4 is a schematic diagram showing the connection between a flexible display panel and multiple sliding protrusions according to an embodiment of this application. The display device 000 may include: a first housing 100, a second housing 200, a flexible display panel 300, and multiple sliding protrusions 400.

[0081] The first housing 100 in the display device 000 can be slidably connected to the second housing 200 in the first direction X.

[0082] The second housing 200 in the display device 000 may include: a support housing 201 and two sliding parts 202 disposed opposite to each other, wherein the support housing 201 is connected to one end of each of the two sliding parts 202.

[0083] The flexible display panel 300 in the display device 000 may have a display surface. For ease of explanation later, the front side of the flexible display panel 300 is the side where the display surface is located, and the back side of the flexible display panel 300 is the side where the non-display surface is located.

[0084] The flexible display panel 300 in the display device 000 may include a flat display portion 301 and a rollable display portion 302. The flat display portion 301 of the flexible display panel 300 may be fixed to the first housing 100. The rollable display portion 302 of the flexible display panel 300 may include a first portion 3021 arranged parallel to the flat display portion 301, and a second portion 3022 located between the first portion 3021 and the flat display portion 301. The second portion 3022 is wound around the side of the support shell 201 facing away from the first housing 100. Here, the support shell 201 may be elongated, and its extension direction may be parallel to a second direction Y, which may be perpendicular to a first direction X.

[0085] In the display device 000, multiple sliding protrusions 400 are connected to the back side of the rollable display section 302 away from the display surface. A portion of the sliding protrusions 400 are slidably connected to one sliding part 202, while another portion is slidably connected to another sliding part 202. That is, the multiple sliding protrusions 400 are divided into two groups, with each group sliding with one of the two sliding parts 202, ensuring that the rollable display section 302 can be unfolded or retracted more stably.

[0086] In this case, the orthographic projections of the multiple sliding protrusions 400 in the display device 000 onto the flexible display panel 300 are all located within the area enclosed by the outer edge of the flexible display panel 300.

[0087] In this configuration, since the orthographic projections of the multiple sliding protrusions 400 in the display device 000 onto the flexible display panel 300 are all located within the area enclosed by the outer edge of the flexible display panel 300, the flexible display panel 300 itself can completely cover the orthographic projections of the multiple sliding protrusions 400, ensuring that the multiple sliding protrusions 400 are not exposed outside the area enclosed by the outer edge of the flexible display panel 300. Therefore, there is no need to add an additional bezel around the edge of the flexible display panel 300 to obscure the multiple sliding protrusions 400, resulting in a narrower bezel around the flexible display panel 300 and thus improving the screen-to-body ratio of the display device 000.

[0088] In summary, this application provides a display device including a first housing, a second housing, a flexible display panel, and a plurality of sliding protrusions. Since the orthographic projections of the plurality of sliding protrusions on the flexible display panel are all located within the area enclosed by the outer edge of the flexible display panel, the flexible display panel itself can completely cover the orthographic projections of the plurality of sliding protrusions, preventing them from being exposed outside the area enclosed by the outer edge of the flexible display panel. Thus, there is no need to add an additional bezel to the edge of the flexible display panel to cover the plurality of sliding protrusions, resulting in a narrower bezel around the flexible display panel and thereby improving the screen-to-body ratio of the display device.

[0089] Optionally, please refer to Figure 5, which is a cross-sectional view of a display device provided in an embodiment of this application. In the first direction X, the distance between any two adjacent sliding protrusions 400 is greater than the width of the sliding protrusion 400 in the first direction X. This ensures that during the unfolding and retraction of the flexible display panel 300, when some sliding protrusions 400 slide to a bent position (i.e., the side of the support shell 201 facing away from the first housing 100), adjacent sliding protrusions 400 connected to the second part 3022 of the rollable display section 302 will not collide or squeeze against each other. This protects the sliding protrusions 400 and the flexible display panel 300 from damage, allowing the rollable display section 302 to unfold and retract smoothly when the user operates the display device 000.

[0090] In this embodiment of the application, please refer to FIG6, which is a schematic diagram of another flexible display panel and multiple sliding protrusions connected according to this embodiment of the application. The flexible display panel 300 may include: a display panel body 310 and a metal support layer 320 stacked together, and the side of the display panel body 310 facing away from the metal support layer 320 includes a display surface.

[0091] In this display panel, multiple sliding protrusions 400 are connected to the side of the metal support layer 320 facing away from the panel body 310. For example, the multiple sliding protrusions 400 are welded to the side of the metal support layer 320 facing away from the panel body 310. In this way, the metal support layer 320 provides additional support to the display panel body 310, enhancing the structural strength of the flexible display panel 300. Furthermore, the welding connection between the multiple sliding protrusions 400 and the metal support layer 320 improves the reliability of the connection, enabling the display device 000 to maintain good stability during prolonged use.

[0092] Optionally, as shown in FIG6, the sliding protrusion 400 in the display device 000 may include a connecting seat 401 and a guide post 402. The connecting seat 401 is connected to the side of the metal support layer 320 opposite to the panel body 310. For example, the connecting seat 401 is welded to the side of the metal support layer 320 opposite to the panel body 310. The guide post 402 is located on the side of the connecting seat 401 opposite to the metal support layer 320, and in the axial direction of the guide post 402, the portion of the guide post 402 protruding from the connecting seat 401 is slidably connected to the sliding portion 202.

[0093] In this application, the end face of the guide post 402 in the sliding protrusion 400 facing the sliding portion 202 is flush with the outer side of the display panel body 310 adjacent to the sliding protrusion 400; or, the outer side of the display panel body 310 adjacent to the sliding protrusion 400 protrudes beyond the end face of the guide post 402 facing the sliding portion 202.

[0094] In this configuration, the guide posts 402 in the sliding protrusions 400 will not protrude beyond the outer surface of the display panel body 310, ensuring that the multiple sliding protrusions 400 are entirely within the area enclosed by the outer surface of the display panel body 310 without occupying additional space. This reduces the width of the bezel of the display device 000, thereby increasing the screen-to-body ratio of the display device 000.

[0095] In this embodiment, please refer to FIG7, which is a cross-sectional view of a portion of the structure in FIG1. ​​When the display device 000 is in the retracted state, a portion of the sliding part 202 in the second housing 200 is embedded between the flat display part 301 and the first portion 3021 of the rollable display part 302, and the portion of the sliding part 202 embedded between the flat display part 301 and the first portion 3021 has a first groove E1. The portion of the guide post 402 in the sliding protrusion 400 that protrudes from the connecting seat 401 is located within the first groove E1.

[0096] In this configuration, a portion of the sliding portion 202 in the second housing 200 is embedded between the flat panel display portion 301 and the first portion 3021 of the rollable display portion 302, further reducing the volume of the display device 000 and making the entire display device more compact in its retracted state. Furthermore, the portion of the sliding portion 202 embedded between the flat panel display portion 301 and the first portion 3021 of the rollable display portion 302 has a first groove E1, and the portion of the guide post 402 in the sliding protrusion 400 that protrudes from the connecting seat 401 is located within the first groove E1. This ensures that the sliding protrusion 400 within the first groove E1 remains between the flat panel display portion 301 and the first portion 3021 of the rollable display portion 302, without occupying space outside the flat panel display portion 301. Therefore, the bezel width of the display device 000 can be further reduced, increasing the screen-to-body ratio of the display device 000.

[0097] Optionally, please refer to Figure 8, which is another exploded view of the display device shown in Figure 1. The sliding portion 202 in the second housing 200 may include: a first sliding member 2021 and a second sliding member 2022. The end of the first sliding member 2021 is fixedly connected to the end of the support housing 201.

[0098] To more clearly see the structure of the second slider 2022 in the sliding part 202, please refer to FIG9, which is a schematic diagram of the structure of a second slider provided in an embodiment of this application. The side of the second slider 2022 in the sliding part 202 facing the first slider 2021 may have: a support strip L, and a mounting groove C formed by the support strip L. A portion of the first slider 2021 is fixedly connected to the second slider 2022 within the mounting groove C, and the support strip L can be used to support the edge area of ​​the rollable display part 302.

[0099] In this application, FIG10 is a partial structural schematic diagram of a second housing provided in an embodiment of this application. As shown in FIG10, in the direction perpendicular to the planar display portion 301, the width d1 of the mounting groove C is greater than the width d2 of the first slider 2021, so that a first sliding groove E1 is formed between the support bar L and the portion of the first slider 2021 located in the mounting groove C. In this way, the first sliding groove E1 can provide a fixed sliding path for the guide post 402 in the sliding protrusion 400, ensuring that the sliding protrusion 400 does not deviate from its path during sliding.

[0100] In this embodiment, please refer to Figures 11 and 12. Figure 11 is a structural schematic diagram of another second slider provided in this embodiment, and Figure 12 is a partial structural schematic diagram of another second housing provided in this embodiment. The support bar L in the second slider 2022 may include: a first sub-support bar L1 and a second sub-support bar L2 disposed opposite to each other in a direction perpendicular to the planar display portion 301, and an arc-shaped sub-support bar L3 for connecting the first sub-support bar L1 and the second sub-support bar L2. The arc-shaped sub-support bar L3 is located on the side of the first slider 2021 opposite to the first housing 100.

[0101] In this application, the first slide rail E1 may include: a first planar slide rail E11 and a second planar slide rail E12, and a curved slide rail (not shown) that communicates with the first planar slide rail E11 and the second planar slide rail E12 respectively.

[0102] The first planar slide groove E11 is located between the portion of the first sub-support bar L1 and the portion of the first sliding member 2021 located within the mounting groove C; the second planar slide groove E12 is located between the portion of the second sub-support bar L2 and the portion of the first sliding member 2021 located within the mounting groove C; and the curved slide groove is located between the arc-shaped sub-support bar L3 and the portion of the first sliding member 2021 located within the mounting groove C.

[0103] In this configuration, during the retraction and unfolding process of the display device 000, the sliding protrusion 400 connected to the first portion 3021 of the rollable display section 302 can slide within the second planar groove E12 in the direction toward the curved groove; the sliding protrusion 400 connected to the second portion 3022 of the rollable display section 302 can slide within the curved groove in the direction toward the first planar groove E11. Thus, with the sliding protrusion 400 present in the first planar groove E11 and absent in the second planar groove E12, the display device 000 can be in a fully unfolded state, allowing most of the area within the rollable display section 302 to unfold to be flush with the planar display section 301.

[0104] During the process of unfolding and retracting the display device 000, the sliding protrusion 400 connected to the first portion 3021 of the rollable display section 302 can slide within the first planar groove E11 in the direction toward the curved groove; the sliding protrusion 400 connected to the second portion 3022 of the rollable display section 302 can slide within the curved groove in the direction toward the second planar groove E12. Thus, with the sliding protrusion 400 present in the second planar groove E12 and absent in the first planar groove E11, the display device 000 can be in a fully retracted state, allowing most of the area within the rollable display section 302 to be hidden inside the first housing 100.

[0105] It should be noted that, as shown in Figure 13, which is another cross-sectional view of part of the structure in Figure 1, and Figure 14, which is a schematic diagram of part of the structure in Figure 10, the outer edge of the display panel body 310 and the metal support layer 320 stacked in the display panel 000 protrudes beyond the outer edge of the metal support layer 320 in the second direction Y. Here, the support strip L in the second slider 2022 can support the portion of the display panel body 310 that protrudes beyond the metal support layer 320 in the second direction Y.

[0106] Optionally, please refer to Figures 13, 14, 15, and 16. Figure 15 is a structural schematic diagram of a first housing provided in an embodiment of this application, and Figure 16 is an assembly schematic diagram of a first housing and a second housing provided in an embodiment of this application. When the display device 000 is in the retracted state, the portion of the first sliding member 2021 in the sliding part 202 located outside the mounting groove C is positioned between the first flat display part 301 and the first part 3021, and the side of the first sliding member 2021 facing away from the second sliding member 2022 may have a first slide rail F1. The first housing 100 in the display device 000 may have a second slide rail 101 slidably connected to the first slide rail F1.

[0107] The first slide F1 and the second slide 101 extend in directions parallel to the first direction X. For example, there are two first slides F1 and two slides 101, and the two first slides F1 and the two second slides 101 are connected to each other.

[0108] This allows the first housing 100 and the second housing 200 to move smoothly during sliding along the first direction X, reducing frictional resistance and improving the smoothness of operation of the display device 000.

[0109] In this embodiment of the application, one of the first slide F1 and the second slide 101 is a dovetail protrusion and the other is a dovetail groove.

[0110] Wherein, after the first housing 100 and the second housing 200 are connected, at least a portion of the dovetail protrusion is located within the dovetail groove. In this case, the cooperation between the dovetail protrusion and the dovetail groove not only provides a reliable guiding function, but also increases the connection strength between the first housing 100 and the second housing 200, reduces the shaking of the second housing 200 during operation, and improves the reliability of the display device 000.

[0111] It should be noted that the first slide rail F1 and the second slide rail 101 can be flexibly designed as complementary forms, that is, the first slide rail F1 and the second slide rail 101 can be interchanged as dovetail protrusions or dovetail grooves; if the first slide rail F1 is designed as a dovetail protrusion, then the second slide rail 101 is matched as a dovetail groove; conversely, if the first slide rail F1 is designed as a dovetail groove, then the second slide rail 101 is adapted to be a dovetail protrusion. This application does not make specific limitations here. It should also be noted that the protrusion in this application is not limited to the shape of a dovetail protrusion, but can also be in the shape of a baseball bat or a snake plate, which is not specifically limited here.

[0112] Optionally, please refer to Figures 8, 17, 18, 19, and 20. Figure 17 is a structural schematic diagram of a second slider provided in an embodiment of this application from another perspective. Figure 18 is a structural schematic diagram of a first covering provided in an embodiment of this application. Figure 19 is a partial structural schematic diagram of Figure 2. Figure 20 is a partial cross-sectional view of Figure 19. The side of the second slider 2022 in the sliding part 202 that is away from the first slider 2021 may have a limiting member 20221, which may be located at the end of the second slider 2022 that is away from the support shell 201.

[0113] The display device 000 may further include a first covering member 500 fixedly connected to the first housing 100, the first covering member 500 having a second groove E2 slidably connected to the limiting member 20221. For example, there are two limiting members 20221 and two second grooves E2, and the two limiting members 20221 and the two second grooves E2 are correspondingly connected. The extending direction of the second groove E2 is parallel to the first direction X, and the end of the second groove E2 near the support housing 201 is a limiting blind end H.

[0114] When the display device 000 is in the unfolded state, the limiting member 20221 abuts against the limiting blind end H in the second slide E2.

[0115] In this configuration, as the second housing 200 slides away from the first housing 100, the limiting member 20221 will slide within the second slide groove E2 until it contacts the limiting blind end H. The contact between the limiting blind end H and the limiting member 20221 ensures that the second housing 200 stops at a predetermined position, effectively preventing excessive sliding of the second housing 200 in the unfolded state, thereby avoiding mechanical damage to the display device 000 due to excessive sliding of the second housing 200.

[0116] In this embodiment of the application, please refer to FIG21, which is a schematic diagram of another first covering component provided in this embodiment of the application. The first covering component 500 in the display device 000 may include: a first base plate 501, and two limiting plates 502 located on both sides of the first base plate 501. The first housing 100 in the display device 000 may be fixed on the first base plate 501 and distributed between the two limiting plates 502.

[0117] The limiting plate 502 in the first covering member 500 may have a first screen pressing strip 5021 on the side opposite to the first base plate 501. The first screen pressing strip 5021 may cover the edge of the flat display section 301 that is parallel to the first direction X.

[0118] In this configuration, the first screen-holding strip 5021 can be used to fix and protect the edge of the flat panel display 301 parallel to the first direction X, preventing it from being subjected to external impacts or damage. Furthermore, the first screen-holding strip 5021 can make the edge of the flat panel display 301 parallel to the first direction X neater, thereby improving the overall aesthetic appearance. Additionally, the first screen-holding strip 5021 can also support and fix the portion of the display panel body 310 protruding from the metal support layer 320 in the Y direction, thus improving the stability of the display panel body 310.

[0119] Optionally, as shown in FIG8, the display device 000 may further include a second cover 600 connected to the first housing 100 away from the second housing 200. The second cover 600 may have a second screen pressing strip 601, and the second screen pressing strip 601 may cover the edge of the flat display portion 301 away from the curved display portion 302.

[0120] In this case, the second screen retainer 601 can fix and protect the edge of the flat panel display 301 that is away from the curled display 302, thereby further preventing it from being subjected to external impacts or damage. In addition, the second screen retainer 601 can also make the edge of the flat panel display 301 away from the curled display 302 more neat, thereby further improving the overall aesthetic appearance.

[0121] In this embodiment, please refer to Figures 8 and 22. Figure 22 is a cross-sectional view of a display device switching between an unfolded state and a retracted state according to an embodiment of this application. The display device 000 further includes a third covering member 700 fixedly connected to the second housing 200.

[0122] When the display device 000 is in the retracted state, a portion of the third cover 700 is located between the second housing 200 and the first base plate 501 in a direction perpendicular to the flat display portion 301, and another portion of the third cover 700 is located on the side of the second portion 3022 away from the support housing 201.

[0123] In this case, during the unfolding process of the flexible display panel 300, the third covering member 700 can cover the rollable display section 302 in the flexible display panel 300. This not only improves the overall aesthetics of the display device 000, but also prevents external collisions and foreign objects from affecting the rollable display section 302.

[0124] Optionally, as shown in Figures 8 and 22, the third covering member 700 in the display device 000 may include a protective plate 701 and a second base plate 702. When the display device 000 is in the retracted state, the second base plate 702 is located between the second housing 200 and the first base plate 501 in a direction perpendicular to the first planar display portion 301, and the protective plate 701 is located on the side of the second portion 3022 facing away from the support housing 201. That is, the second portion 3022 can be sandwiched between the support housing 201 and the protective plate 701.

[0125] In this case, the protective plate 701 can press the second part 3022 of the roll-up display section 302 in the flexible display panel 300 during the process of the display device 000 going from the unfolded state to the retracted state, so that the flexible display panel 300 will not curl up, thereby making the flatness of the flexible display panel 300 better.

[0126] It should be noted that the side of the support shell 201 facing away from the first housing 100 is an arc-shaped surface, and the side of the protective plate 701 facing the support shell 201 is also an arc-shaped surface, so that an arc-shaped channel can be formed between the two, thereby allowing the second part 3032 in the rollable display 303 to slide better within the arc-shaped channel, so as to ensure that the rollable display 303 can be better unfolded or retracted.

[0127] Optionally, please refer to Figure 23, which is a schematic diagram of another flexible display panel and multiple sliding protrusions connected according to an embodiment of this application. The flexible display panel 300 in the display device 000 may further include a non-display portion 303 located on the side of the rollable display portion 302 opposite to the flat display portion 301. Here, the non-display portion 303 remains on the side opposite to the flat display portion 301 during the unfolding and retraction of the flexible display panel 300 and does not participate in the winding action. Therefore, the non-display portion 303 is usually thicker than the rollable display portion 302 and can be used to support the edge portion of the flexible display panel 300.

[0128] The plurality of sliding protrusions 400 may further include at least two auxiliary sliding protrusions 410. Each of the at least two auxiliary sliding protrusions 410 is connected to the back surface of the non-display portion 303, and one of the at least two auxiliary sliding protrusions 410 is slidably connected to a sliding portion 202, while another auxiliary sliding protrusion 410 is slidably connected to the other sliding portion 202.

[0129] In this way, by connecting at least two auxiliary sliding protrusions 410 to different sliding portions 202, more support points can be provided during the sliding of the flexible display panel 300. These additional support points can help disperse the forces generated when the flexible display panel 300 slides, reduce the wobbling of the flexible display panel 300 during the sliding process, and thus improve the smoothness of the sliding of the flexible display panel 300.

[0130] For example, the distance between the auxiliary sliding protrusion 410 of the plurality of sliding protrusions 400 and the adjacent sliding protrusion 400 in the first direction X is greater than the distance between two adjacent sliding protrusions 400 in the first direction X.

[0131] In this embodiment, when the display device 000 needs to switch from a retracted state to an unfolded state, the user can apply an external pulling force to the side of the third cover 700 away from the first housing 100, causing the second housing 200 to slide in the first direction X away from the first housing 100. During this process, the portion of the rollable display 302 located on the side of the support housing 201 away from the first housing 100 can slide relative to the support housing 201, so that the portion of the rollable display 302 that slides out relative to the support housing 201 can be flush with the flat display 301. At the same time, the portion of the rollable display 302 hidden inside the first housing 100 can continue to slide in the direction toward the support housing 201.

[0132] When the display device 000 needs to switch from an unfolded state to a retracted state, the user can apply pressure to the side of the third cover 700 away from the first housing 100, causing the second housing 200 to slide in the first direction X toward the first housing 100. During this process, the portion of the rollable display 302 located on the side of the support housing 201 away from the first housing 101 can slide relative to the support housing 201, allowing the portion of the rollable display 302 that slides out relative to the support housing 201 to remain inside the first housing 100. Simultaneously, the portion of the rollable display 302 that slides out relative to the support housing 201 can continue to slide in the direction toward the support housing 201.

[0133] Optionally, please refer to Figure 24, which is an exploded view of a display device provided in an embodiment of this application. The display device 000 may further include a battery 800 and a motherboard 900, which are distributed on the side of the first housing 100 opposite to the flat panel display section 301.

[0134] In this application, the battery 800 is primarily responsible for providing power to the various electronic components in the display device 000. The motherboard 900 is the core control center of the display device 000, responsible for coordinating the work between various hardware components, processing information input from the user, and transmitting the processed data to the flexible display panel 300 for the user to view. In addition, the motherboard 900 is also responsible for communicating with the battery 800 and controlling the charging status of the battery 800.

[0135] In this embodiment of the application, as shown in FIG24, the first housing 100 of the display device 000 has a support groove Q on the side opposite to the flat display section 301.

[0136] In this device, the battery 800 and the motherboard 900 are stacked in the support groove Q, or the battery 800 and the motherboard 900 are arranged side by side in the support groove Q in the first direction X.

[0137] In this application, the battery 800 and motherboard 900 in the display device 000 can be stacked in the support groove Q or arranged side-by-side in the support groove Q in the first direction X. Therefore, the battery 800 and motherboard 900 can have multiple assembly methods in the support groove Q. For clarity, the embodiments of this application will be illustrated using the following two optional implementation methods as examples:

[0138] For a first optional implementation, please refer to Figures 25 and 26. Figure 25 is an exploded view of another display device provided in an embodiment of this application, and Figure 26 is a cross-sectional view of another display device provided in an embodiment of this application. In the case where the battery 800 and the motherboard 900 are stacked within the support groove Q in the display device 000, the motherboard 900 is closer to the bottom surface of the support groove Q relative to the battery 800. The bottom surface of the support groove Q may have a clearance groove P, which is used to accommodate protruding devices distributed on the side of the motherboard 900 opposite to the battery 800. For example, there are two clearance grooves P, and the two clearance grooves P are disposed opposite each other on the bottom surface of the support groove Q.

[0139] In this configuration, by stacking the motherboard 900 and battery 800 and utilizing the clearance slot P to accommodate protruding components on the motherboard 900, internal space can be effectively utilized, resulting in a more compact layout within the first housing 100. This frees up more space for the battery 800, allowing for a thicker battery 800 and thus improving the overall battery life of the display device 000.

[0140] A second optional implementation is shown in Figures 27 and 28. Figure 27 is an exploded view of another display device provided in an embodiment of this application, and Figure 28 is a cross-sectional view of another display device provided in an embodiment of this application. In the case where the battery 800 and the motherboard 900 in the display device 000 are arranged side-by-side in the support groove Q in the first direction X, the battery 800 is closer to the second housing 200 than the motherboard 900, and the motherboard 900 includes at least two sub-motherboards 901 stacked in a direction perpendicular to the planar display portion 301. For example, in this application, the motherboard 900 has two sub-motherboards 901.

[0141] In this case, since the battery 800 can occupy more space in the width and thickness directions, a larger capacity battery 800 can be used, thereby further improving the battery life of the display device 000.

[0142] Optionally, as shown in FIG8, the display device 000 may further include a connecting strap 1000, the two ends of which are respectively connected to the side of the first housing 100 opposite to the flat display portion 301. For example, when the display device 000 is used as a smartwatch, the connecting strap 1000 can be a wristband, which can be worn on the user's wrist. Alternatively, when the display device 000 is used as a head-mounted device, the connecting strap 1000 can be a headband connecting strap, which can be worn on the user's head. Alternatively, when the display device 000 is used as a smartphone, the connecting strap 1000 can be detached from the first housing 100.

[0143] In this embodiment, please refer to FIG29, which is a cross-sectional view of another display device provided in this embodiment switching between an unfolded state and a retracted state. The first covering member 500 in the display device 000 may have an opening (not shown) on the side opposite to the flexible display panel 300. The display device 000 may further include a vital sign detection module 1100 fixedly connected to the first covering member 500, at least a portion of which may be exposed through the opening in the first covering member 500. Detection is performed after the vital sign detection module 1100 contacts the user's wrist skin. It should be noted that the vital sign detection module 1100 may have the function of detecting the user's electrocardiogram, blood oxygen, etc.

[0144] In summary, this application provides a display device including a first housing, a second housing, a flexible display panel, and a plurality of sliding protrusions. Since the orthographic projections of the plurality of sliding protrusions on the flexible display panel are all located within the area enclosed by the outer edge of the flexible display panel, the flexible display panel itself can completely cover the orthographic projections of the plurality of sliding protrusions, preventing them from being exposed outside the area enclosed by the outer edge of the flexible display panel. Thus, there is no need to add an additional bezel to the edge of the flexible display panel to cover the plurality of sliding protrusions, resulting in a narrower bezel around the flexible display panel and thereby improving the screen-to-body ratio of the display device.

[0145] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0146] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
