Specific embodiments

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0052] FIG1 schematically illustrates a display device in a first state, and FIG2 schematically illustrates a display device in a second state. As shown in FIG1 and FIG2 , some embodiments of the present disclosure provide a display device, which may be (but not limited to) a mobile phone, a personal data assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a video camera, a game console, a calculator, a computer monitor, a car display (e.g., an odometer display, etc.), a navigator, a cockpit controller and / or display, a camera view display (e.g., a display of a rearview camera in a vehicle), an electronic photo, an electronic billboard or sign, etc. FIG1 and FIG2 illustrate the display device as a mobile phone as an example.

[0053] Continuing to refer to Figures 1 and 2, the display device includes a housing component 200 and a display module 100. The display device includes at least a first state and a second state. When the display device is in the first state, all or most of the display module 100 is accommodated in the housing component 200, as shown in Figure 1. When the display device is in the second state, all or most of the display module 100 extends from the housing component 200 and flattens, as shown in Figure 2. The flattening here refers to being accommodated in the housing component 200 relative to the first state, and does not mean that the display module 100 is located in an ideal plane. In actual application, the display module 100 may also have a small angle of curvature in the second state.

[0054] For example, as shown in FIG2 , along a first direction X, the display module 100 includes a first end and a second end relative to each other, and the first end of the display module 100 is connected to the accommodating assembly 200. When the first end of the display module 100 rotates in the accommodating assembly 200 around a rotation axis parallel to the second direction Y, the entire or most area of ​​the display module 100 can be wound in the accommodating assembly 200, thereby causing the display device to enter a first state. When the second end of the display module 100 is pulled in a direction away from the accommodating assembly 200, the display module 100 is unwound from the accommodating assembly 200 and flattened outside the accommodating assembly 200, thereby causing the display device to enter a second state. The winding and unwinding of the display module 100 can be completed manually by the user or driven by the accommodating assembly 200, and this is not limited in this embodiment of the present application.

[0055] The receiving assembly 200 is used to connect and accommodate the display module 100 .

[0056] Exemplarily, as shown in Figure 20, the accommodating component 200 includes a shell 230, and a accommodating cavity is provided in the shell 230. When the display device is in the first state, all or most of the area of ​​the display module 100 is accommodated in the accommodating cavity, so that the display module 100 is not easily affected by external collisions under the protection of the shell 230, and the space occupied by the display device is reduced.

[0057] In actual use, the housing 230 may also be provided with a battery and a control board electrically connected to the display module 100. The battery is used to provide power to the display module 100, and the control board is used to control the display image of the display module 100. The housing 230 may also be provided with a central processing unit, storage, a mainboard, an antenna, etc., which are not limited in the embodiments of the present disclosure.

[0058] The display module 100 includes a flexible display panel 110, which is bendable. The flexible display panel 110 can be an electroluminescent display panel or a photoluminescent display panel. In the case where the flexible display panel 110 is an electroluminescent display panel, the electroluminescent display panel can be an organic light-emitting diode (OLED) display panel or a quantum dot light-emitting diode (QLED) display panel. In the case where the flexible display panel 110 is a photoluminescent display panel, the photoluminescent display device can be a quantum dot photoluminescent display panel.

[0059] Some embodiments of the present disclosure are described by taking the flexible display panel 110 as an organic light-emitting diode (OLED) display panel as an example.

[0060] When the display device is in the second state, in order to make the flexible display panel 110 located outside the accommodating component 200 in a flat state, the display module 100 also includes a supporting component, which is connected to one side of the flexible display panel 110 and is used to support the flexible display panel 110 to prevent the flexible display panel 110 from bending.

[0061] Exemplarily, the flexible display panel 110 includes a light emitting side and a backlight side arranged opposite to the light emitting side, and the supporting assembly is connected to the backlight side of the flexible display panel 110 .

[0062] Figure 3 is a view taken along the direction A in Figure 2 , and Figure 4 is a view taken along the direction B in Figure 3 . As shown in Figures 3 and 4 , the support assembly includes a plurality of support bars 120 and locking blocks 130 .

[0063] The support bar 120 has a width along the first direction X, a length along the second direction Y, and a thickness along the third direction Z. The support bar 120 can be in the form of an elongated strip, meaning its length is much greater than its width. The support bar 120 can also be in the form of a thin plate, meaning its thickness is much less than its width, to reduce the thickness of the support assembly and, consequently, the overall thickness of the display module 100, facilitating its storage within the housing assembly 200.

[0064] The support bar 120 is connected to one side of the flexible display panel 110. For example, the support bar 120 is connected to one side of the flexible display panel 110 by bonding. Of course, the support bar 120 can also be connected to one side of the flexible display panel 110 by ultrasonic welding. The support bar 120 can also be integrated with the substrate of the flexible display panel 110. The embodiment of the present disclosure does not limit the connection method between the support bar 120 and the flexible display panel 110.

[0065] The support bar 120 may be made of a material that is relatively strong and not easily deformed, such as metal, carbon fiber, glass fiber, etc.

[0066] The plurality of support bars 120 are spaced apart to form a gap between two adjacent support bars 120. The flexible display panel 110 in the gap is not supported by the support bars 120. When the display device is in the first state, the flexible display panel 110 in the gap can be bent, so that at least a portion of the display module 100 is stored in the receiving assembly 200 by being rolled up.

[0067] 3 and 4 , the plurality of support bars 120 are spaced apart along a first direction X, and the minimum distance between two adjacent support bars 120 is equal. The first direction X may be the direction in which the display module 100 extends from or retracts into the accommodating assembly 200 .

[0068] Figure 5 schematically illustrates a partial structural diagram of two adjacent support bars. As shown in Figure 5, one of the two adjacent support bars 120 includes a first side wall 121, and the other includes a second side wall 122. The first side wall 121 and the second side wall 122 are opposite and spaced apart, such that a gap is formed between the first side wall 121 and the second side wall 122.

[0069] Exemplarily, a support bar 120 includes both a first sidewall 121 and a second sidewall 122. For example, the left support bar 120 and the right support bar 120 in FIG5 each include two sidewalls along the first direction X: the sidewall facing right is the first sidewall 121, and the sidewall facing left is the second sidewall 122. Between two adjacent support bars 120, a gap is formed between the first sidewall 121 of one support bar 120 and the second sidewall 122 of the other support bar 120.

[0070] The gap between the first side wall 121 and the second side wall 122 includes an unlocking area FA and a locking area LA. The gap between the first side wall 121 and the second side wall 122 refers to the area where the orthographic projection of the flexible display panel 110 is located between the first side wall 121 and the second side wall 122. The unlocking area FA and the locking area LA may be divided by a virtual line, i.e., there is no physical structure separating the two areas.

[0071] The locking block 130 is disposed between the first side wall 121 and the second side wall 122 and is movable so that the locking block 130 can be moved from the unlocking area FA to the locking area LA or from the locking area LA to the unlocking area FA.

[0072] The locking block 130 may be connected to one side of the flexible display panel 110 or to the support bar 120 .

[0073] Illustratively, a slide rail is provided on one side of the flexible display panel 110 , and the slide rail is located between the first side wall 121 and the second side wall 122 . The locking block 130 is slidably connected to the slide rail so that the locking block 130 can move along the slide rail.

[0074] For example, the first side wall 121 and / or the second side wall 122 are provided with a slide groove extending along the length of the support bar 120, and the locking block 130 is provided with a slider that is embedded in the slide groove and allows the locking block 130 to slide along the slide groove. In addition, the cooperation between the slider and the slide groove can prevent the locking block 130 from falling off.

[0075] Figure 6 schematically illustrates the structure of the locking block in the locking area, Figure 7 is a cross-sectional view of line CC in Figure 6, and Figure 8 is a force analysis diagram of Figure 7. As shown in Figures 6 and 7, when the locking block 130 is in the locking area LA, the portion of the gap between the first side wall 121 and the second side wall 122 located in the locking area LA is filled by the locking block 130, so that the locking block 130 contacts the first side wall 121 on one side along the first direction X and contacts the second side wall 122 on the other side along the first direction X. In other words, the locking block 130 contacts both the first side wall 121 and the second side wall 122 simultaneously.

[0076] The locking block 130 may include a mating surface. When the locking block 130 is located in the locking area LA, the mating surface of the locking block 130 contacts the first side wall 121 and the second side wall 122 .

[0077] As shown in Figure 8, when two adjacent support bars 120 respectively generate a bending tendency in the direction indicated by the arc arrow, the locking block 130 located between the two adjacent support bars 120 blocks the bending path of the two support bars 120, thereby preventing the two support bars 120 from bending in the direction indicated by the arc arrow, so that the flexible display panel 110 remains flat with the cooperation of the support bars 120 and the locking block 130.

[0078] Continuing with FIG8 , the flexible display panel 110 includes a first region 223a domain 110a connected to the left support bar 120, a third region 110c connected to the right support bar 120, and a second region 223b domain 110b corresponding to the locking block 130. When the first region 223a domain 110a and the third region 110c of the flexible display panel 110 bend relative to the second region 223b domain 110b in the direction indicated by the circular arrow, the first region 223a domain 110a drives the left support bar 120 to press against the locking block 130, and the third region 110c drives the right support bar 120 to press against the locking block 130. Both the left and right support bars 120 are prevented from further movement by the locking block 130, thereby preventing the first region 223a domain 110a and the third region 110c from bending relative to the second region 223b domain 110b, thereby maintaining the display module 100 in a flat state. Specifically, the locking block 130 applies a reaction force F1 to the left support bar 120 and a reaction force F2 to the right support bar 120, so that the left support bar 120 cannot continue to move under the action of the reaction force F1, and the right support bar 120 cannot continue to move under the action of the reaction force F2.

[0079] The locking block 130 may be made of a material with good rigidity (such as metal, hard plastic, etc.) to prevent the locking block 130 from being deformed under the pressure of the support bar 120 .

[0080] When the locking block 130 is located in the locking area LA, the entire structure of the locking block 130 may be located in the locking area LA, or only a portion of the structure of the locking block 130 may be located in the locking area LA. For example, the locking block 130 being located in the locking area LA means that the mating surface of the locking block 130 is located in the locking area LA.

[0081] Exemplarily, when the display device is in the second state, the area of ​​the display module 100 located outside the accommodating component 200 is the working area, and the locking block 130 set in the working area is now located in the locking area LA. The locking block 130 and the support bar 120 located in the locking area LA cooperate to keep the flexible display panel 110 located in the working area in a flat state.

[0082] When the locking block 130 is located in the unlocking area FA, the flexible display panel 110 located between two adjacent support bars 120 can be bent, so that the display module 100 can be bent in the area between the two adjacent support bars 120, so that the display module 100 can be stored in the accommodating component 200 by being wound.

[0083] For example, when the display device is in the first state or the second state, the area of ​​the display module 100 located in the accommodating component 200 is a non-working area, and the locking block 130 set in the non-working area is located in the unlocking area FA at this time, so that two adjacent support bars 120 set in the non-working area can be bent, so that the display module 100 can be stored in the accommodating component 200 by winding.

[0084] Figures 9 and 10 illustrate a display device support solution in related art. In these figures, HG represents a hinge, CN represents a rotation axis, and SP represents a structural component. Adjacent structural components are connected by a hinge, with a sliding groove within the hinge and a sliding shaft within the structural component. In the curled state, the sliding shaft's position within the sliding groove allows for the absorption of misalignment of varying radii. In the flattened state, the display panel is supported through the cooperation of the sliding shaft and the sliding groove. However, machining and assembly errors in the hinge and structural components in this solution directly affect the curling and flattening performance of the display device.

[0085] Compared to the solutions in the related art, in the embodiment of the present disclosure, a plurality of spaced support bars 120 are provided on one side of the flexible display panel 110, and a locking block 130 is provided between two adjacent support bars 120. When the locking block 130 is located in the locking area LA, the locking block 130 simultaneously contacts the two adjacent support bars 120, thereby preventing the relative movement of the two adjacent support bars 120. This makes the flexible display panel 110 connected to the support bars 120 less likely to bend, thereby achieving support for the flexible display panel 110. Since the locking block 130 can support the flexible display panel 110 by simultaneously contacting the two support bars 120 in the locking area LA, the processing precision requirements for the support bars 120 and the locking block 130 are reduced.

[0086] Two adjacent support bars 120 are connected to one side of the flexible display panel 110, and the minimum distance between the two adjacent support bars 120 along the first direction X within the locking area LA is a. The size of the locking block 130 along the first direction X can be slightly larger than a. When the locking block 130 moves into the locking area LA, it squeezes the two adjacent support bars 120, causing both adjacent support bars 120 to move away from the locking block 130, thereby stretching the flexible display panel 110 located between the two adjacent support bars 120, causing the flexible display panel 110 to generate an elastic force. The elastic force acts on the two adjacent support bars 120, causing the two adjacent support bars 120 to clamp the locking block 130 located between them. On the one hand, the locking block 130 is not easily removed from between two adjacent support bars 120; on the other hand, the flexible display panel 110 is slightly stretched, so that the flattening effect of the flexible display panel 110 is better; on the other hand, since the locking block 130 and the two adjacent support bars 120 can be interference fit, the processing error or assembly error of the locking block 130 and the support bar 120 can be accommodated.

[0087] The minimum distance between the first side wall 121 and the second side wall 122 in the locking area LA is smaller than the minimum distance between the first side wall 121 and the second side wall 122 in the unlocking area FA. In the locking area LA, the locking block 130 contacts both the first side wall 121 and the second side wall 122 simultaneously. Specifically, the dimension of the locking block 130 perpendicular to the support bar 120 is approximately equal to the minimum distance between the first side wall 121 and the second side wall 122. When the minimum distance between the first side wall 121 and the second side wall 122 in the unlocking area FA is greater than the minimum distance between the first side wall 121 and the second side wall 122 in the locking area LA, the locking block 130 is no longer in contact with the first side wall 121 and / or the second side wall 122, thereby allowing the flexible display panel 110 located between the first side wall 121 and the second side wall 122 to bend, allowing the display module 100 to be wound within the accommodating assembly 200.

[0088] 11 schematically shows a structure diagram of the locking block located in the unlocking area FA. Exemplarily, when the locking block 130 is located in the unlocking area FA, the locking block 130 may not contact the first side wall 121 or the second side wall 122 .

[0089] Fig. 12 is a cross-sectional view of line DD in Fig. 11. As shown in Fig. 12, a first gap b1 is formed between the locking block 130 and the first side wall 121, and a second gap b2 is formed between the locking block 130 and the second side wall 122.

[0090] Figure 13 is a schematic diagram of the bent state of Figure 12. As shown in Figure 13, due to the formation of a first gap b1 between the locking block 130 and the first side wall 121, and a second gap b2 between the locking block 130 and the second side wall 122, when the two ends of the structure shown in Figure 13 respectively generate bending motion trends along the arc arrows, the area of ​​the flexible display panel 110 corresponding to the first gap b1 and the area of ​​the flexible display panel 110 corresponding to the second gap b2 are bent.

[0091] Figure 14 is a schematic diagram of the structure after bending shown in Figure 13. As shown in Figure 14, when the flexible display panel 110 continues to bend so that the locking block 130 contacts the first side wall 121 and the second side wall 122, the flexible display panel 110 stops bending.

[0092] As can be seen from FIG. 11 to FIG. 14 , when the locking block 130 is located in the unlocking area FA, the display module 100 can be bent, so that the display module 100 can be received in the receiving assembly 200 in a rolled manner.

[0093] The unlocking area FA and the locking area LA can be arranged along the extension direction of the support bar 120. At this time, the locking block 130 can move along the extension direction of the support bar 120 to achieve the position switching of the locking block 130 in the unlocking area FA and the locking area LA.

[0094] Of course, the unlocking area FA and the locking area LA can also be arranged in a direction perpendicular to the flexible display panel 110. For example, the locking block 130 is generally wedge-shaped. When the tip of the locking block 130 is inserted between two adjacent support bars 120 in a direction perpendicular to the flexible display panel 110 and contacts the first side wall 121 and the second side wall 122, the locking block 130 is located in the locking area LA. When the locking block 130 moves away from the flexible display panel 110 and loses contact with the first side wall 121 and the second side wall 122, the locking block 130 is located in the unlocking area FA. In addition, the unlocking area FA and the locking area LA can also be arranged in other directions, which are not listed here.

[0095] Compared with the unlocking area FA and the locking area LA being arranged in a direction perpendicular to the flexible display panel 110, the unlocking area FA and the locking area LA are arranged along the extension direction of the support bar 120, and the size of the display module 100 in the direction perpendicular to the flexible display panel 110 is smaller.

[0096] A guide surface may be provided within the unlocking area FA to guide the locking block 130 when it moves from the unlocking area FA to the locking area LA, or vice versa. Furthermore, when the locking block 130 forms an interference fit with the first side wall 121 and the second side wall 122, the dimension of the locking block 130 perpendicular to the support bar 120 is slightly larger than the distance between the first side wall 121 and the second side wall 122 within the locking area LA. The provision of the guide surface allows the locking block 130 to smoothly enter the locking area LA along the guide surface, preventing the locking block 130 from becoming stuck due to its larger size.

[0097] The guide surface may be provided on the first side wall 121 , or on the second side wall 122 , or may be provided on both the first side wall 121 and the second side wall 122 .

[0098] Illustratively, the first sidewall 121 includes a first guide surface 123 located in the unlocking area FA. As the unlocking area FA points toward the locking area LA, the first guide surface 123 gradually approaches the second sidewall 122. As the unlocking area FA points toward the locking area LA, the first guide surface 123 gradually approaches the second sidewall 122. In other words, the passage defined by the first guide surface 123 and the second sidewall 122, through which the locking block 130 moves, gradually narrows as it moves from the unlocking area FA toward the locking area LA. The narrower the passage, the more precise the positioning of the locking block 130, allowing the locking block 130 to smoothly enter the locking area LA.

[0099] Exemplarily, the second side wall 122 includes a second guide surface 124 located in the unlocking area FA. From the unlocking area FA toward the locking area LA, the second guide surface 124 gradually approaches the first side wall 121. As the unlocking area FA points toward the locking area LA, the second guide surface 123 gradually approaches the first side wall 121. That is, the channel defined by the second guide surface 124 and the first side wall 121 for the movement of the locking block 130 gradually narrows along the direction from the unlocking area FA toward the locking area LA. The narrower the channel, the more accurate the position of the locking block 130, thereby allowing the locking block 130 to smoothly enter the locking area LA.

[0100] For example, the first sidewall 121 includes a first guide surface 123, and the second sidewall 122 includes a second guide surface 124. The unlocking area FA points in the direction of the locking area LA, and the first guide surface 123 gradually approaches the second sidewall 122, and the second guide surface 123 gradually approaches the first sidewall 121. That is, the channel defined by the second guide surface 124 and the first guide surface 123, through which the locking block 130 moves, gradually narrows in the direction from the unlocking area FA toward the locking area LA. The narrower the channel, the more precise the position of the locking block 130, allowing the locking block 130 to smoothly enter the locking area LA.

[0101] Furthermore, when a guide surface is provided within the unlocking area FA and the locking block 130 is located within the unlocking area FA, the locking block 130 may contact both the first guide surface 123 and the second guide surface 124. When the flexible display panel 110 bends between the first side wall 121 and the second side wall 122, the first side wall 121 and the second side wall 122 squeeze the locking block 130, causing the locking block 130 to move away from the locking area LA under the guidance of the first guide surface 123 and the second guide surface 124, thereby preventing the locking block 130 from affecting the bending of the display module 100.

[0102] The locking block 130 may include an arcuate surface. When the locking block 130 is located in the unlocking area FA, the arcuate surface contacts the first guide surface 123 and / or the second guide surface 124. That is, the mating surface of the locking block 130 is an arcuate surface. The arcuate surface forms a linear contact with the first guide surface 123 or the second guide surface 124, reducing the contact area between the locking block 130 and the first guide surface 123 or the second guide surface 124, thereby reducing friction between the locking block 130 and the first guide surface 123 or the second guide surface 124.

[0103] For example, as shown in FIG6 and FIG11 , the orthographic projection of the locking block 130 on the flexible display panel 110 may be circular as a whole.

[0104] The support bar 120 may be provided with a first stopper 120a, and the locking block 130 may be provided with a second stopper 130a. When the locking block 130 is located in the locking area LA, the first stopper 120a cooperates with the second stopper 130a to prevent the locking block 130 from escaping from the locking area LA, thereby making the support assembly more reliable in supporting the flexible display panel 110. The first stopper 120a and the second stopper 130a cooperate to prevent the locking block 130 from escaping from the locking area LA, which means that the locking block 130 is prevented from escaping from the locking area LA without being subjected to forces other than the support bar 120 and the elastic member 140 (described later).

[0105] The first stop 120a and the second stop 130a can be formed by a combination of a groove and a protrusion. When the locking block 130 is located in the locking area LA, the protrusion engages with the groove. For example, as shown in FIG11 , the first stop 120a is a groove 125, and the second stop 130a is a protrusion. For example, the first stop 120a is a protrusion, and the second stop 130a is a groove 125.

[0106] For example, as shown in Figure 11, the groove 125 is an arc-shaped groove 125, and the protrusion is also arc-shaped (for example, when the locking block 130 protects an arc surface, the area where the arc surface is located is a protrusion). The arc-shaped groove 125 and the arc-shaped protrusion cooperate reliably and are easy to process. In addition, when a force is applied to the locking block 130 in a direction parallel to the support bar 120, the arc-shaped protrusion can easily be disengaged from the arc-shaped groove 125, thereby enabling the locking block 130 to move from the locking area LA to the unlocking area FA.

[0107] Of course, the first stop portion and the second stop portion may also be other fitting devices such as buckles.

[0108] The support assembly may also include an elastic member 140 connected to the locking block 130. When the locking block 130 is in the locking area LA, the elastic member 140 elastically deforms and generates an elastic force directed from the locking area LA toward the unlocking area FA. As the locking block 130 moves from the locking area LA toward the unlocking area FA, the elastic force assists the movement of the locking block 130, accelerating its movement and thereby improving the response speed of the support assembly.

[0109] The elastic member 140 may be made of an elastic material, such as rubber, plastic, metal, etc. When the locking block 130 is located in the locking area LA, the elastic member 140 may be deformed in tension or in compression.

[0110] Since the locking block 130 needs to move between the locking area LA and the unlocking area FA, the elastic member 140 needs to have a large deformation. In actual application, the elastic member 140 can be bent into a certain shape, and the deformation requirement is met by bending or stretching the elastic member 140.

[0111] 6 , the elastic member 140 includes a plurality of bending sections. When the locking block 130 is located in the locking area LA, the number of bending sections of the elastic member 140 increases or the bending angle of the bending section decreases, thereby generating elastic force in the elastic member 140.

[0112] The elastic member 140, the locking block 130 and the support bar 120 can be prepared separately and connected or matched with each other by assembly. The elastic member 140, the locking block 130 and the support bar 120 can also be made by an integral molding process.

[0113] Exemplarily, the elastic member 140 , the locking block 130 and the support bar 120 are all made of plastic, and the elastic member 140 , the locking block 130 and the support bar 120 can be integrally formed by an injection molding process.

[0114] For example, the elastic member 140 , the locking block 130 and the support bar 120 are all made of metal, and the elastic member 140 , the locking block 130 and the support bar 120 can be etched on a metal sheet through an etching process.

[0115] Of course, the elastic member 140 , the locking block 130 and the support bar 120 can also be integrally formed by laser cutting or other methods, and the integral forming processes are not listed one by one here.

[0116] When the elastic member 140, locking block 130, and support bar 120 are manufactured through an integrated molding process, the relative positional errors among the elastic member 140, locking block 130, and support bar 120 are reduced. Furthermore, since there is no need to assemble the elastic member 140, locking block 130, and support bar 120, the assembly difficulty is reduced. When preparing the display module 100, the support assembly can be simply connected to one side of the flexible display panel 110.

[0117] Figure 15 schematically illustrates the structure of a display device. As shown in Figure 15 , multiple locking blocks 130 are disposed between the first sidewall 121 and the second sidewall 122. These locking blocks 130 are spaced apart along the extension direction of the support bar 120. When the display device is in the second state, if one of the locking blocks 130 is released from the locking area LA, the remaining locking blocks 130 can still cooperate with the support bar 120 to continue supporting the flexible display panel 110, thereby improving the support assembly's reliability in supporting the flexible display panel 110. Furthermore, the provision of multiple locking blocks 130 ensures a more uniform force on the support bar 120.

[0118] 15 , two locking blocks 130 may be provided between two adjacent support bars 120. When two locking blocks 130 are provided between two adjacent support bars 120, the movement directions of the two locking blocks 130 may be the same or opposite.

[0119] For example, when the locking blocks 130 move from the unlocking area FA toward the locking area LA, the two locking blocks 130 may move in the same direction, toward each other, or in opposite directions.

[0120] Of course, the number of locking blocks 130 between two adjacent support bars 120 can also be three, four, five, etc., and can be flexibly set according to the size of the flexible display panel 110 and the size of the locking blocks 130 in actual application.

[0121] The receiving assembly 200 may include a guide member, and when the display device switches between the first state and the second state, the guide member may drive the locking block 130 to move between the unlocking area FA and the locking area LA.

[0122] For example, when the display module 100 switches from the first state to the second state, at least a portion of the display module 100 extends from the accommodating assembly 200 (i.e., the second end of the display module 100 moves away from the accommodating assembly 200). The area of ​​the display module 100 extending from the accommodating assembly 200 is the working area. During the extension of the working area from the accommodating assembly 200, the locking block 130 located in the working area is driven by the guide member to move from the unlocking area FA to the locking area LA, so that the working area in the display module 100 is in a flattened state.

[0123] Figure 16 schematically illustrates a partial structural diagram of a display device. For example, as shown in Figure 16, the guide member includes a first sub-member 221, which is fixedly connected to the accommodating assembly 200. When the second end of the display module 100 moves away from the accommodating assembly 200 (from left to right in the figure), the locking block 130 sequentially passes through the first sub-member 221 from left to right. Once the locking block 130 passes through the first sub-member 221, it is driven by the first sub-member 221 to move from the unlocking area FA to the locking area LA.

[0124] For example, when the display module 100 switches from the second state to the first state, at least a portion of the display module 100 retracts from outside the accommodating assembly 200 and is rolled into the accommodating assembly 200. The area of ​​the display module 100 rolled into the accommodating assembly 200 is the non-working area. During the process of the working area retracting from outside the accommodating assembly 200 into the accommodating assembly 200 (i.e., during the process of the working area of ​​the display module 100 being transformed into the non-working area), the locking block 130 located in the working area is driven by the guide member to move from the locking area LA to the unlocking area FA, thereby converting the working area of ​​the display module 100 from the flattened state to the bendable state, thereby allowing the display module 100 to be rolled into the accommodating assembly 200.

[0125] Figure 17 schematically illustrates a partial structural diagram of another display device. For example, as shown in Figure 17, the guide member includes a second sub-member 222, which is fixedly connected to the accommodating assembly 200. When the second end of the display module 100 moves toward the accommodating assembly 200 (from right to left in the figure), the locking block 130 sequentially passes through the second sub-member 222 from right to left. Once the locking block 130 passes through the second sub-member 222, it is driven by the second sub-member 222 to move from the locking area LA to the unlocking area FA.

[0126] It should be noted that during the extension or retraction of the display module 100, the locking blocks 130 arranged perpendicular to the support bars 120 sequentially pass through the guides and, driven by the guides, move between the unlocking area FA and the locking area LA. Specifically, the locking blocks 130 that have passed through the guides move between the unlocking area FA and the locking area LA, while the locking blocks 130 that have not passed through the guides remain in position. This allows for flexible adjustment of the working area of ​​the display module 100.

[0127] Figure 18 schematically illustrates a structural diagram of another display device, and Figure 19 schematically illustrates a structural diagram of a guide member. As shown in Figures 18 and 19 , the guide member includes a first sub-member 221 and a second sub-member 222, which are arranged opposite each other to form a guide track 223. The guide track 223 extends perpendicularly to the support bar 120 and includes a first region 223a located proximal to the accommodating component 200 and a second region 223b located distal to the accommodating component 200. In a direction perpendicular to the support bar 120, the first region 223a is arranged opposite to the unlocking region FA, while the second region 223b is arranged opposite to the locking region LA. The guide track 223 also includes a transition region 223c connecting the first region 223a and the second region 223b.

[0128] The locking block 130 passing through the guide is the action locking block 130 , and at least part of the structure of the action locking block 130 is located in the guide track 223 , so that the action locking block 130 moves along the guide track 223 , thereby being able to switch between the locking area LA and the unlocking area FA.

[0129] Exemplarily, the guide member is located on the side of the support bar 120 away from the flexible display panel 110, and part of the structure of the locking block 130 protrudes from the side of the support bar 120 away from the flexible display panel 110, so that the end of the locking block 130 away from the flexible display panel 110 is located in the guide track 223.

[0130] Continuing to refer to Figures 3 and 4, the display module 100 includes a third end and a fourth end relative to each other along a direction parallel to the support bar 120. The display module 100 may also include a plurality of sliding shafts 150, and the plurality of sliding shafts 150 are arranged at intervals along a direction perpendicular to the support bar 120. The sliding shafts 150 may be located at the third end of the display module 100, or at the fourth end of the display module 100, or at both the third end and the fourth end.

[0131] Exemplarily, the sliding shaft 150 is connected to the support bar 120 . For example, the sliding shaft 150 and the support bar 120 are an integral structure, or the sliding shaft 150 is connected to a side of the support bar 120 away from the flexible display panel 110 .

[0132] Fig. 20 schematically shows a structural diagram of a receiving assembly 200. As shown in Fig. 20, the receiving assembly 200 includes a spiral track 240, and at least a portion of the sliding shaft 150 is embedded in the spiral track 240 and can move along the spiral track 240.

[0133] Exemplarily, the third and fourth ends of the display module 100 are both provided with sliding shafts 150, and both ends of the accommodating component 200 are both provided with spiral tracks 240. The sliding shafts 150 slide along the spiral tracks 240, so that the display module 100 is wound along the spiral tracks 240 in the accommodating component 200.

[0134] Continuing with FIG20 , the accommodating assembly 200 may further include a driving arm 210. One end of the driving arm 210 engages with at least one sliding shaft 150, and the other end of the driving arm 210 is rotatably connected to the center of the spiral track 240. When the driving arm 210 rotates along the center of the spiral track 240, the one end of the driving arm 210 pulls the sliding shaft 150 to slide along the spiral track 240, thereby causing the sliding shaft 150 to pull the display module 100 along the spiral track 240, causing the display module 100 to be wound within the accommodating assembly 200.

[0135] Illustratively, a long hole 211 is provided in the driving arm 210 , and the end of the sliding shaft 150 is located in the long hole 211 . When the sliding shaft 150 slides along the spiral track 240 , the sliding shaft 150 moves along the long hole 211 in the driving arm 210 .
