Description

Display device and electronic device Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a display device and an electronic device. Background Art

[0002] With the development of display technology, foldable display devices (such as mobile phones) that can meet users' needs for large-size display screens and can be portable or small in size for easy storage are gradually becoming popular among users.

[0003] At present, dual-screen foldable display devices are relatively common. In order to further bring out the advantages of foldable display devices, for example, in order to further expand the size of the display screen that can be displayed by the display device, how to develop and design high-performance three-screen foldable or even more-screen foldable display devices has become a problem that needs to be solved urgently.

[0004] Utility Model Content

[0005] The embodiments of the present application provide a display device and an electronic device, which are intended to optimize the drop resistance of the display device and reduce the probability of damage to the display screen, thereby improving the reliability of the foldable display device and extending its service life.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a display device is provided. The display device includes a first component, a second component, a third component, a first connecting portion, and a second connecting portion.

[0008] The first component and the second component are rotatably connected via a first connection; the second component and the third component are rotatably connected via a second connection. The first component and the second component move toward or away from each other via the first connection, and the second component and the third component move toward or away from each other via the second connection, thereby converting the display device between a flattened state and a folded state.

[0009] In which, in the folded state, the first component, the second component and the third component are stacked along the first direction, the first connecting portion is located on the same side of the first component and the second component, the second connecting portion is located on the same side of the second component and the third component, and the first connecting portion and the second connecting portion are arranged on both sides of the second component along the second direction; the second direction intersects with the first direction.

[0010] In the folded state, the orthographic projection of the boundary of the first component away from the first connecting part on the reference plane is farther away from the orthographic projection of the boundary of the second connecting part away from the first connecting part on the reference plane, and the orthographic projection of the boundary of the third component away from the second connecting part on the reference plane is closer to the orthographic projection of the second connecting part on the reference plane relative to the orthographic projection of the boundary of the first connecting part away from the second connecting part on the reference plane; the reference plane is perpendicular to the first direction.

[0011] In the display device provided by the embodiment of the present application, the orthographic projection of the boundary of the first component away from the first connection part on the reference plane is set to be farther away from the orthographic projection of the first connection part on the reference plane relative to the orthographic projection of the boundary of the second connection part away from the first connection part on the reference plane, and the orthographic projection of the boundary of the third component away from the second connection part on the reference plane is closer to the orthographic projection of the second connection part on the reference plane relative to the orthographic projection of the boundary of the first connection part away from the second connection part on the reference plane. That is, when the first component and the second component are folded, the side of the first component away from the first connection part protrudes from the second connection part in the direction away from the first connection part, and when the second component and the third component are folded, the side of the third component away from the second connection part is retracted toward the second connection part relative to the side of the first connection part away from the second connection part.

[0012] Through the above-mentioned arrangement, the probability of the display device suffering from problems such as screen breakage or damage can be effectively reduced in accidents such as the display device falling in the folded state. For example, when the first component, the second component, and the third component are folded, the second component that is prone to screen breakage and damage is retracted relative to the boundary of the first component with stronger protection capability (for example, greater hardness), and the third component that is prone to screen breakage and damage is retracted relative to the boundary of the first connecting portion with stronger protection capability (for example, greater hardness). Therefore, in accidents such as the display device falling in the folded state, the falling force point of the display device can be transferred to the first component and the first connecting portion with stronger protection capability, thereby protecting the second component and the third component from damage, effectively reducing the risk of the display device suffering from problems such as screen breakage and damage. In a possible implementation of the first aspect, the display device includes a first middle frame, a second middle frame, a third middle frame, a first hinge, a second hinge, and a display screen.

[0013] The first middle frame and the second middle frame are connected by a first rotating shaft; the second middle frame and the third middle frame are connected by a second rotating shaft. In the unfolded state, the display screen is arranged on the same side of the first middle frame, the second middle frame, the third middle frame, the first rotating shaft and the second rotating shaft; the display screen includes a first sub-screen, a fourth sub-screen, a second sub-screen, a fifth sub-screen and a third sub-screen connected in sequence. The first component includes the first middle frame and the first sub-screen, and the first sub-screen is arranged on one side of the first middle frame; the second component includes the second middle frame and the second sub-screen, and the second sub-screen is arranged on one side of the second middle frame; the third component includes the third middle frame and the third sub-screen, and the third sub-screen is arranged on one side of the third middle frame; the first connecting part includes the first rotating shaft and the fourth sub-screen, and the fourth sub-screen is arranged on one side of the first rotating shaft; the second connecting part includes the second rotating shaft and the fifth sub-screen, and the fifth sub-screen is arranged on one side of the second rotating shaft.

[0014] In the folded state, the first middle frame, the second middle frame and the third middle frame are stacked in sequence along the first direction, and the display surface of the first sub-screen faces the display surface of the second sub-screen, and the third sub-screen is located on the side of the third middle frame away from the second middle frame.

[0015] Therefore, while maintaining the portability of the display device, the display of a small-sized screen of the display device in the folded state can also be guaranteed.

[0016] In a possible implementation of the first aspect, the orthographic projection of the boundary of the first middle frame away from the first rotation axis on the reference plane is farther away from the orthographic projection of the first rotation axis on the reference plane relative to the orthographic projection of the boundary of the fifth sub-screen away from the first rotation axis on the reference plane, and the orthographic projection of the boundary of the third middle frame away from the second rotation axis on the reference plane is closer to the orthographic projection of the second rotation axis on the reference plane relative to the orthographic projection of the boundary of the first rotation axis away from the second rotation axis on the reference plane.

[0017] That is, the left side of the first middle frame (based on the orientation of Figure 7) is set to protrude from the left side of the fifth sub-screen, and the right side of the third middle frame is set to be retracted relative to the right side of the first rotating shaft.

[0018] The above-mentioned arrangement can effectively prevent the display screen from being damaged in accidents such as the display device falling. For example, when the first component, the second component, and the third component are folded, the fifth sub-screen is located on the left side of the folded display device. By setting the left side of the first middle frame to protrude from the left side of the fifth sub-screen, the probability of the fifth sub-screen contacting with external structures can be effectively reduced during the display device falling, thereby preventing it from being damaged. Similarly, by setting the right side of the third middle frame to be retracted relative to the right side of the first rotating shaft, the probability of the right side of the third middle frame, which has lower stability and lower hardness, contacting with external structures can be reduced when the display device falls and causes the right side of the display device in the folded state to be subjected to force. The force-bearing position is transferred to the connection position between the first component and the second component (i.e., the first middle frame of the first connection part, which has higher hardness), thereby preventing the display screen corresponding to the third component from being damaged and cracked from the right side, effectively improving the reliability of the display device and extending the service life of the display device.

[0019] In a possible implementation of the first aspect, the display device further includes a motherboard and a battery, which are disposed within the first component. This can enhance the hardness and weight of the first component, thereby improving the drop reliability of the folded display device. For example, the probability of the first component, which has a higher hardness, falling downward after a drop is increased, thereby protecting the second and third components, which are susceptible to breakage or damage, and optimizing the display device's drop and shatterproof performance.

[0020] In possible implementations of the first aspect, the thickness of the first component is greater than the thickness of the second component and greater than the thickness of the third component. Furthermore, / or the weight of the first component is greater than the weight of the second component and greater than the weight of the third component. Furthermore, / or the hardness of the first component is greater than the hardness of the second component and greater than the hardness of the third component.

[0021] By setting the thickness of the first component to be greater than the thickness of the second component and the thickness of the third component, the protection capability of the first sub-screen can be improved and the risk of the first sub-screen being broken can be reduced. When the force position is transferred to the first component, the thicker first component has a higher anti-fall and anti-breakage capability.

[0022] By setting the weight of the first component to be heavier, the probability of the first component falling downward (for example, on the ground) can be increased after the display device in the folded state falls, thereby further transferring the force position to the first component, improving the protection capability of the fragile screen and the easily damaged second and third components, further improving the reliability of the display device, and extending its service life.

[0023] In a possible implementation of the first aspect, the display device further includes a communication component disposed within the first component and at least partially disposed at an end of the first component distal from the first connecting portion. When the display device is folded, the portion of the first component where the communication component is disposed protrudes beyond the second and third components, thereby preventing the second and third components from obstructing a signal transmission path for the communication component and improving signal transmission efficiency of the communication component.

[0024] In a possible implementation of the first aspect, the communication component includes an antenna, which is provided at an end of the first component away from the first connecting portion.

[0025] In a possible implementation of the first aspect, the display device further includes at least one third connecting portion. The display device includes a plurality of second components, and the number of the second components is odd; two adjacent second components are rotatably connected via the third connecting portion.

[0026] In the folded state, the orthographic projection of the boundary of the third connection part away from the first connection part on the same side as the second connection part on the reference plane is closer to the orthographic projection of the boundary of the first component away from the first connection part on the reference plane, and the orthographic projection of the boundary of the third connection part away from the second connection part on the same side as the first connection part on the reference plane is closer to the orthographic projection of the second connection part on the reference plane relative to the orthographic projection of the boundary of the first connection part away from the second connection part on the reference plane.

[0027] Through this embodiment, multi-screen folding of the display device can be achieved, thereby further increasing the display size of the display device when in full-screen display, or further improving the portability of the display device after folding. At the same time, the third connecting part can be retracted relative to the side of the first component with stronger protection capability away from the first connecting part, or retracted relative to the side of the second connecting part with stronger protection capability away from the first connecting part, thereby protecting the third connecting part and the second component that are easily broken or damaged from external damage.

[0028] In a possible implementation of the first aspect, when the display device includes a display screen: in the folded state, among the plurality of second components, two second sub-screens corresponding to two second components closest to the first component are disposed away from each other, and two second sub-screens corresponding to two second components closest to the third component are disposed opposite each other. Thus, when the display device is in the folded state, the third sub-screen can be located on an outer surface of the display device, thereby facilitating the display device to display a small screen in the folded state.

[0029] In a second aspect, an electronic device is provided, comprising a processor and a display device provided by any one of the embodiments of the first aspect, wherein the processor is electrically connected to the display device.

[0030] The technical effects brought about by the electronic device in the second aspect can be referred to the technical effects brought about by the display device in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The embodiment of the present application provides an electronic device (refer to the electronic device 1000 in FIG1 ), which may be, for example, a mobile phone, a tablet computer, a computer, a personal digital assistant (PDA), a television, a smart wearable product (e.g., a smart watch, a smart bracelet), a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a rechargeable small household appliance (e.g., a soymilk maker, a robot vacuum), a drone, a radar, aerospace equipment, an on-board device, a vehicle, or other different types of user devices or terminal devices; the electronic device may also be a network device such as a base station. The embodiment of the present application does not impose any particular restrictions on the specific form of the electronic device.

[0050] FIG1 is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application.

[0051] As shown in FIG1 , the electronic device 1000 includes a display device 100. The display device 100 may be any device that displays either moving (eg, video) or fixed (eg, still images), and whether text or images.

[0052] 1 , the electronic device 1000 further includes a processor 200. The processor 200 is electrically connected to the display device 100 to control the display device 100 to display images.

[0053] Exemplarily, the processor 200 may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor.

[0054] Exemplarily, the processor 200 may be packaged in the display device 100 . For example, when the electronic device 1000 is a mobile phone, the processor 200 may be integrated on a mainboard of the display device 100 , or may be assembled inside a rear shell of the display device 100 .

[0055] Alternatively, illustratively, the processor 200 may be independent of the display device 100. For example, when the electronic device 1000 is a computer, the display device 100 serves as a display screen of the computer, and the processor 200 may be disposed in the computer host and electrically connected to the display screen.

[0056] It will be understood that the structural description of the electronic device 1000 in the embodiment of the present application does not constitute a limitation on the specific structure of the electronic device 1000. The electronic device 1000 may include more or fewer components than those shown in FIG1 , or may have a different combination or arrangement of components than that shown in FIG1 .

[0057] An embodiment of the present application further provides a display device 100, which can be independently used in the above-mentioned electronic device 1000, or can be combined with other structures (such as a processor 200 or other electronic devices) and then used in the above-mentioned electronic device 1000.

[0058] The following embodiments illustrate the structure of the display device 100 by taking a three-screen foldable display device as an example.

[0059] Figures 2 and 7 are perspective views of the display device 100 in a folded state according to an embodiment of the present application. Figure 3 is a perspective view of the display device 100 in an unfolded state according to an embodiment of the present application. Figures 4 and 5 are views of the display device 100 in the unfolded state according to an embodiment of the present application from different directions.

[0060] In some embodiments, as shown in FIG. 2 , the display device 100 includes a first component 101 , a second component 102 , a third component 103 , a first connecting portion 104 , and a second connecting portion 105 .

[0061] 2 , the first component 101 and the second component 102 are rotatably connected via a first connecting portion 104 , and the second component 102 and the third component 103 are rotatably connected via a second connecting portion 105 .

[0062] The first component 101 and the second component 102 move toward or away from each other through the first connecting portion 104 , and the second component 102 and the third component 103 move toward or away from each other through the second connecting portion 105 , so that the display device 100 switches between the flattened state and the folded state.

[0063] 2 , in the folded state, the first component 101 , the second component 102 and the third component 103 are stacked along the first direction X.

[0064] The first direction X is the thickness direction of the first component 101 , the second component 102 and the third component 103 .

[0065] Exemplarily, referring to FIG. 2 , in the folded state, the first component 101 , the second component 102 and the third component 103 are sequentially arranged along the first direction X.

[0066] Alternatively, in other embodiments, the display device 100 may also present other folding methods. For example, in the folded state, the first component 101, the second component 102 and the third component 103 are stacked along the first direction X, and the third component 103 is folded between the first component 101 and the second component 102.

[0067] 2 , in the folded state, the first connecting portion 104 is located on the same side of the first component 101 and the second component 102 , the second connecting portion 105 is located on the same side of the second component 102 and the third component 103 , and the first connecting portion 104 and the second connecting portion 105 are respectively arranged on both sides of the second component 102 along the second direction Y.

[0068] 3 , in the unfolded state, the first component 101 , the second component 102 , the third component 103 , the first connecting portion 104 and the second connecting portion 105 are sequentially arranged along the second direction Y.

[0069] The second direction Y intersects the first direction X. For example, the second direction Y may be perpendicular to the first direction X. The second direction Y is the arrangement direction of the first component 101 , the second component 102 and the third component 103 when the display device 100 is unfolded.

[0070] As shown in FIG7 , in the folded state, the orthographic projection Q1 of the boundary of the first component 101 away from the first connecting portion 104 on the reference plane P is farther away from the orthographic projection of the first connecting portion 104 on the reference plane P than the orthographic projection Q2 of the boundary of the second connecting portion 105 away from the first connecting portion 104 on the reference plane P. The orthographic projection Q3 of the boundary of the third component 103 away from the second connecting portion 105 on the reference plane P is closer to the orthographic projection of the second connecting portion 105 on the reference plane P than the orthographic projection Q4 of the boundary of the first connecting portion 104 away from the second connecting portion 105 on the reference plane P. The reference plane N is perpendicular to the first direction X.

[0071] That is, when the display device 100 is in a folded state, the boundary of the first component 101 away from the first connecting portion 104 protrudes from the boundary of the second connecting portion 105 away from the first connecting portion 104 in a direction away from the first connecting portion 104, and the boundary of the third component 103 away from the second connecting portion 105 retracts inward relative to the boundary of the first connecting portion 104 away from the second connecting portion 105 in a direction close to the second connecting portion 105.

[0072] In the display device 100 provided in the embodiment of the present application, the above-mentioned arrangement can effectively reduce the probability of the display device 100 having problems such as screen breakage or damage in the event of an accident such as the display device 100 falling in the folded state. For example, when the first component 101, the second component 102 and the third component 103 are folded, the second component 102, which is prone to screen breakage and damage, is retracted relative to the boundary of the first component 101, which has a stronger protective capability (for example, greater hardness or thickness), and the third component 103, which is prone to screen breakage and damage, is retracted relative to the boundary of the first connecting portion 104, which has a stronger protective capability. Thus, in the event of an accident such as the display device 100 falling in the folded state, the falling force point of the display device 100 can be transferred to the protective portion 104. The force is applied to the first component 101 and the first connecting portion 104, where the force is relatively strong. For example, in the folded state, when the left side surface of the display device 100 (based on the orientation in FIG7 ) touches the ground, the force point is located on the side of the protruding first component 101. When the right side surface of the display device 100 (based on the orientation in FIG7 ) touches the ground, the force point is located on the outer surface of the protruding first connecting portion 104, thereby protecting the retracted second component 102 and the third component 103 and other structures from damage, and effectively reducing the risk of the display device 100 having problems such as screen breakage and damage.

[0073] In some embodiments, as shown in FIG. 3 , the display device 100 includes a first middle frame 10 , a second middle frame 20 , a third middle frame 30 , a first rotation axis H1 , a second rotation axis H2 , and a display screen M.

[0074] For example, referring to FIG. 3 , the first middle frame 10 , the second middle frame 20 , and the third middle frame 30 are sequentially connected via a first rotation axis H1 and a second rotation axis H2 , respectively.

[0075] For example, referring to FIG3 , the interconnected sides of the first middle frame 10, the second middle frame 20, and the third middle frame 30 can be sides with a longer length or sides with a shorter length. The figure only uses the connection of the sides with a longer length as an example to schematically illustrate the structure of the display device 100, and does not constitute a limitation thereto.

[0076] For example, referring to FIG. 3 , the display device 100 may further include a rear case N, and the first middle frame 10 , the second middle frame 20 , and the third middle frame 30 may be structures for connecting the display screen M of the display device 100 and the rear case.

[0077] For example, referring to Figure 3, the rear shell N is arranged on the non-display side (the side that does not emit light) of the display screen M. Referring to Figure 3, the rear shell N and the display screen M are arranged on both sides of the middle frame structure formed by the first middle frame 10, the second middle frame 20 and the third middle frame 30, and are connected through the middle frame structure to realize the assembly of the display device 100.

[0078] Exemplarily, the first middle frame 10, the second middle frame 20 and the third middle frame 30 can serve as the side shell of the display device 100, and together with the rear shell N form a groove. Some components of the display device 100, such as batteries and other devices, can be set in the groove. Exemplarily, the first middle frame 10, the second middle frame 20 and the third middle frame 30 can also include a middle frame body located in the aforementioned groove. Some components of the display device 100, such as sensors, chips, etc., can be fixed in the aforementioned groove through the middle frame body.

[0079] For example, referring to Figure 5, the back shell N may include a first sub-shell N1, a second sub-shell N2 and a third sub-shell N3, wherein the first sub-shell N1, the second sub-shell N2 and the third sub-shell N3 correspond to the first middle frame 10, the second middle frame 20 and the third middle frame 30 respectively, and the first sub-shell N1, the second sub-shell N2 and the third sub-shell N3 are separated from each other, thereby facilitating the display device 100 to be unfolded or folded.

[0080] 3 , the display screen M in the display device 100 serves as a side surface of the display device 100 and is used to display images.

[0081] For example, referring to Figure 3, in the expanded state, the display screen M is arranged on the same side of the first middle frame 10, the second middle frame 20, the third middle frame 30, the first rotation axis H1 and the second rotation axis H2, so that the display device 100 can display images on one side of the display screen M.

[0082] Exemplarily, the display screen M may be a liquid crystal display (LCD); the display screen M may also be an electroluminescent display or a photoluminescent display. If the display screen M is an electroluminescent display, the electroluminescent display may be an organic light-emitting diode (OLED) display or a quantum dot light-emitting diode (QLED) display. If the display screen M is a photoluminescent display, the photoluminescent display device may be a quantum dot photoluminescent display.

[0083] It can be understood that the side of the display screen M away from the first middle frame 10, the second middle frame 20, the third middle frame 30, the first rotation axis H1 and the second rotation axis H2 is the display side (ie, the side used for luminous display).

[0084] 4 is a front view of the display device 100 provided in an embodiment of the present application, FIG5 is a rear view of the display device 100 provided in an embodiment of the present application, and FIG6 is a side view of the display device 100 provided in an embodiment of the present application in an unfolded state.

[0085] Exemplarily, referring to FIG4 , the display screen M includes a first sub-screen M1 , a fourth sub-screen M4 , a second sub-screen M2 , a fifth sub-screen M5 and a third sub-screen M3 that are sequentially connected.

[0086] It can be understood that, referring to Figure 4, the aforementioned first component 101 may include a first middle frame 10 and a first sub-screen M1, and the first sub-screen M1 is arranged on one side of the first middle frame 10. Similarly, the aforementioned second component 102 may include a second middle frame 20 and a second sub-screen M2, and the second sub-screen M2 is arranged on one side of the second middle frame 20. The aforementioned third component 103 may include a third middle frame 30 and a third sub-screen M3, and the third sub-screen M3 is arranged on one side of the third middle frame 30. The first connecting part 104 includes a first rotating shaft H1 and a fourth sub-screen M4, and the fourth sub-screen M4 is arranged on one side of the first rotating shaft H1. The second connecting part 105 includes a second rotating shaft H2 and a fifth sub-screen M5, and the fifth sub-screen M5 is arranged on one side of the second rotating shaft H2.

[0087] For example, referring to FIG5 , when the display device includes a housing N, the first component 101 may further include a first sub-housing N1 , the second component 102 may further include a second sub-housing N2 , and the third component 103 may further include a third sub-housing N3 .

[0088] For example, referring to Figure 4, the display screen M is a full-screen design, that is, the first sub-screen M1, the second sub-screen M2, the third sub-screen M3, the fourth sub-screen M4 and the fifth sub-screen M5 are arranged in one piece, so that the display device 100 can maintain a good display effect in the unfolded state.

[0089] For example, referring to Figures 3, 4 and 6, when the first middle frame 10, the second middle frame 20 and the third middle frame 30 are unfolded (that is, the entire display screen M is unfolded), the first sub-screen M1, the second sub-screen M2, the third sub-screen M3, the fourth sub-screen M4 and the fifth sub-screen M5 are located on the same plane, realizing the display of a large-size screen of the display device 100.

[0090] Referring to Figure 7, when the first middle frame 10 and the second middle frame 20 are folded, the display surface of the first sub-screen M1 faces the display surface of the second sub-screen M2. When the second middle frame 20 and the third middle frame 30 are folded, the third sub-screen M3 is located on the side of the third middle frame 30 facing away from the second middle frame 20.

[0091] That is, when the first middle frame 10, the second middle frame 20 and the third middle frame 30 are folded, the first sub-screen M1 and the second sub-screen M2 are folded on the inside (i.e., not exposed), and the third sub-screen M3 is located on the outer surface, thereby reducing the size of the display device 100 and improving portability, while also being able to display a small-size screen through the third sub-screen M3.

[0092] It can be understood that in this case, referring to Figure 7 , the fourth sub-screen M4 is located on the side of the first rotation axis H1 closer to the second rotation axis H2, and the fifth sub-screen M5 is located on the side of the second rotation axis H2 farther from the first rotation axis H1. That is, when the display device 100 is folded, the fourth sub-screen M4 is folded inward (i.e., not exposed), and the fifth sub-screen M5 is located on the right side surface.

[0093] 3 and 7 , the first middle frame 10 and the second middle frame 20 are rotatably connected via a first rotation axis H1 , and the second middle frame 20 and the third middle frame 30 are rotatably connected via a second rotation axis H2 .

[0094] Among them, the first middle frame 10 and the second middle frame 20 can move toward or away from each other through the first rotation axis H1, and the second middle frame 20 and the third middle frame 30 can move toward or away from each other through the second rotation axis H2, so that the display screen M can be switched between a flattened state (see Figure 3) and a folded state (see Figure 7).

[0095] For example, when the display screen M is converted from an unfolded state to a folded state, the first middle frame 10 and the second middle frame 20 move toward each other toward the side where the display screen M is set through the first rotation axis H1, and the second middle frame 20 and the third middle frame 30 move away from each other toward the side away from the display screen M, so that the display screen M is in a folded state (as shown in Figure 7), so that the first sub-screen M1 and the second sub-screen M2 are folded on the inside, and the third sub-screen M3 is located on the outer surface.

[0096] It can be understood that the aforementioned "rotational connection" refers to a connection method that can realize switching between unfolding and folding states, for example, it can be a hinge (that is, the first rotation axis H1 and the second rotation axis H2 are hinged structures), or it can be other connection methods that can realize switching between unfolding and folding states.

[0097] For example, “the first middle frame 10 and the second middle frame 20 are rotatably connected via the first rotation axis H1 ” means that the first rotation axis H1 can enable the first middle frame 10 and the second middle frame 20 to be folded or unfolded relative to each other. The same applies to the second middle frame 20 and the third middle frame 30 .

[0098] Referring to FIG3 , by setting a rotational connection between the first middle frame 10 and the second middle frame 20, and a rotational connection between the second middle frame 20 and the third middle frame 30, the display device 100 provided in the embodiment of the present application can include an unfolded state and a folded state. Referring to FIG3 , the unfolded state of the display device 100 may refer to a state in which the first middle frame 10, the second middle frame 20, and the third middle frame 30 are roughly in the same plane. In this state, the display screen M of the display device 100 is in a flat state, capable of providing a display screen of the maximum size. Referring to FIG7 , the folded state of the display device 100 may refer to a state in which the first middle frame 10, the second middle frame 20, and the third middle frame 30 are stacked in sequence. In this state, the display device 100 is stacked in a three-dimensional direction, reducing the size on a two-dimensional plane (e.g., a plane parallel to the first sub-screen M1), thereby facilitating portability.

[0099] It is understandable that the display device 100 can also include other states, for example, there is a roughly obtuse angle between the first sub-screen M1 and the second sub-screen M2, or only the second middle frame 20 and the third middle frame 30 are folded, etc. The aforementioned unfolded state and folded state of this application do not limit the application state of the display device 100.

[0100] FIG7 is a side view of the display device 100 provided in an embodiment of the present application in a folded state.

[0101] 7 , when the display device 100 is in a folded state, the first middle frame 10 , the second middle frame 20 and the third middle frame 30 are stacked in sequence along a first direction X.

[0102] The first direction X is the thickness direction of the first middle frame 10 , the second middle frame 20 and the third middle frame 30 .

[0103] Referring to Figure 7, when the display device 100 is in a folded state, the orthographic projection Q1 of the boundary of the first middle frame 10 away from the first rotation axis H1 on the reference plane P is farther away from the orthographic projection of the first rotation axis H1 on the reference plane N than the orthographic projection Q2 of the boundary of the fifth sub-screen M5 away from the first rotation axis H1 on the reference plane P. The orthographic projection Q3 of the boundary of the third middle frame 30 away from the second rotation axis H2 on the reference plane P is closer to the orthographic projection of the second rotation axis H2 on the reference plane P than the orthographic projection Q4 of the boundary of the first rotation axis H1 away from the second rotation axis H2 on the reference plane P.

[0104] That is, when the display device 100 is in a folded state, the boundary of the first middle frame 10 away from the first rotation axis H1 protrudes beyond the boundary of the fifth sub-screen M5 away from the first rotation axis H1 in a direction away from the first rotation axis H1, and the boundary of the third middle frame 30 away from the second rotation axis H2 retracts inward in a direction close to the second rotation axis H2 relative to the boundary of the first rotation axis H1 away from the second rotation axis H2.

[0105] For example, referring to Figures 3 to 6 , when the display device 100 is in a flattened state, or referring to Figure 7 , when the display device 100 is in a folded state, a distance d1 between the side of the first middle frame 10 away from the first rotation axis H1 and the centerline L1 of the first rotation axis H1 is set to be greater than a distance d2 between the centerline L1 of the first rotation axis H1 and the centerline L2 of the second rotation axis H2, and a distance d3 between the side of the third middle frame 30 away from the second rotation axis H2 and the centerline L2 of the second rotation axis H2 is set to be less than a distance d2 between the centerlines L1 of the first rotation axis H1 and the centerlines L2 of the second rotation axis H2. That is, referring to Figure 3 , d1>d2>d3. Thereby, the boundary of the first middle frame 10 away from the first rotation axis H1 protrudes from the boundary of the fifth sub-screen M5 away from the first rotation axis H1 in the direction away from the first rotation axis H1, and the boundary of the third middle frame 30 away from the second rotation axis H2 is retracted in the direction close to the second rotation axis H2 relative to the boundary of the first rotation axis H1 away from the second rotation axis H2.

[0106] It should be noted that the aforementioned "centerline L1 of the first rotation axis H1" is used to indicate the centerline between the first middle frame 10 and the second middle frame 20. For example, the centerline L1 of the first rotation axis H1 can be the centerline of the two adjacent sides of the first middle frame 10 and the second middle frame 20. Or, for example, if the first rotation axis H1 is roughly rectangular, the centerline L1 of the first rotation axis H1 can be the centerline of the side of the rectangular, and the direction of extension of the centerline is the same as the direction of extension of the two adjacent sides of the first middle frame 10 and the second middle frame 20. Or, for example, if the first rotation axis H1 is roughly cylindrical, the centerline L1 of the first rotation axis H1 can be the axis of the cylinder. Similarly, the aforementioned "centerline L2 of the second rotation axis H2" is used to indicate the centerline between the third middle frame 30 and the second middle frame 20.

[0107] For example, when the sizes of the first rotation axis H1 and the second rotation axis H2 are approximately the same, referring to Figures 4 and 7, by setting d1>d2>d3, in the second direction Y, the size of the first middle frame 10 is larger than the size of the second middle frame 20, and the size of the third middle frame 30 is smaller than the size of the second middle frame 20.

[0108] The second direction Y is parallel to the surface of the display screen M and perpendicular to the first rotation axis H1 and the second rotation axis H2. That is, when the display device 100 is in the unfolded state, the second direction Y is the direction from the first middle frame 10 to the second middle frame 20. For example, referring to Figures 3 to 5, the second direction Y is the width direction of the first middle frame 10, the second middle frame 20, and the third middle frame 30. That is, in this embodiment, the width of the first middle frame 10 is greater than the width of the second middle frame 20, and the width of the third middle frame 30 is less than the width of the second middle frame 20.

[0109] In the display device 100 provided in the embodiment of the present application, when the first middle frame 10 and the second middle frame 20 are folded (see Figure 7, the display surface of the first sub-screen M1 faces the display surface of the second sub-screen M2), the side of the first middle frame 10 away from the first rotation axis H1 protrudes in the direction away from the first rotation axis H1 beyond the side of the fifth sub-screen M5 away from the first rotation axis H1 along the direction perpendicular to the first rotation axis H1 and parallel to the surface of the display screen M (i.e., the second direction Y), and when the second middle frame 20 and the third middle frame 30 are folded (see Figure 7, the third sub-screen M3 is located on the side of the third middle frame 30 away from the second middle frame 20), the side of the third middle frame 30 away from the second rotation axis H2 is retracted inward relative to the first rotation axis H1 toward the direction close to the second rotation axis H2.

[0110] That is, referring to Figure 7, when the first middle frame 10, the second middle frame 20 and the third middle frame 30 are folded (that is, the display device 100 is in a folded state, the first sub-screen M1 and the second sub-screen M2 are folded on the inside, and the third sub-screen M3 is located on the outside), the side boundary of the left side of the first middle frame 10 (according to the orientation in Figure 7) protrudes from the side boundary of the left side of the fifth sub-screen M5 (the left side in the folded state shown in Figure 7), and the side boundary of the right side of the third middle frame 30 (according to the orientation in Figure 7) is retracted relative to the side boundary on the right side of the first rotation axis H1 (the right side in the folded state shown in Figure 7).

[0111] Through the above-mentioned arrangement, the display screen M can be effectively prevented from being damaged in accidents such as the display device 100 falling. For example, referring to Figure 7, when the first middle frame 10, the second middle frame 20 and the third middle frame 30 are folded (that is, when the display screen M is folded), the fifth sub-screen M5 is exposed on the left side (according to the orientation in Figure 7) of the display device 100. By setting the left side edge of the first middle frame 10 to protrude from the left side edge of the fifth sub-screen M5, when the display device 100 falls and the left side edge of the display device 100 in the folded state is subjected to force, the probability of the exposed fifth sub-screen M5 contacting the external structure (such as the ground) can be effectively reduced, thereby preventing the fifth sub-screen M5 from being damaged. Similarly, referring to Figure 7, the right side of the third middle frame 30 is set to be retracted relative to the right side of the first rotation axis H1. This can reduce the probability of the right side of the third middle frame 30 with lower stability and hardness contacting the external structure when the display device 100 falls, resulting in force on the right side of the display device 100 in the folded state. The force position is transferred to the connection position between the first middle frame 10 and the second middle frame 20 (that is, the first rotation axis H1, which has higher hardness), thereby avoiding damage and cracking of the display screen M corresponding to the third middle frame 30 (that is, the third sub-screen M3) from the right side, effectively improving the reliability of the display device 100 and extending the service life of the display device 100.

[0112] It can be understood that, in addition to achieving the purpose of the left and right sides of the first component 101 protruding from the second component 102 and the third component 103 in the folded state by setting the width of the first middle frame 10, the second middle frame 20 and the third middle frame 30 as in the aforementioned embodiment, it can also be achieved in other ways. For example, the aforementioned purpose can also be achieved by setting the width of the first sub-shell N1, the second sub-shell N2 and the third sub-shell N3. It can be understood that any other arbitrary implementation methods that can make the boundary of the first component 101 away from the first connecting part 104 protrude from the boundary of the second connecting part 105 away from the first connecting part 104 in the direction away from the first connecting part 104, so that the boundary of the third component 103 away from the second connecting part 105 is retracted in the direction close to the second connecting part 105 relative to the boundary of the first connecting part 104 away from the second connecting part 105 are all within the scope of protection of this application, and this application does not impose any restrictions on this.

[0113] FIG8 is a schematic structural diagram of the first component 101 provided in an embodiment of the present application.

[0114] In some embodiments, as shown in FIG8 , the display device 100 may further include a mainboard 40 and a battery 50 . Referring to FIG8 , the mainboard 40 and the battery 50 are disposed in the first component 101 .

[0115] Exemplarily, the mainboard 40 and the battery 50 may be disposed in a receiving cavity surrounded by the first sub-shell N1, the first middle frame 10, and the first sub-screen M1.

[0116] It can be understood that in the embodiments of the present application and the structure shown in Figure 8, only the structure of the first component 101 is illustrated as an example. The first component 101 may include more or fewer structures than shown in Figure 8, or the layout of the structure in the first component 101 may be different from that shown in Figure 8. The embodiments of the present application do not limit this.

[0117] By arranging the main board 40 and the battery 50 in the first component 101, the hardness and weight of the first component 101 can be enhanced, thereby improving the drop reliability of the display device 100 in the folded state. For example, the probability of the first component 101 with higher hardness falling below (such as the ground) after falling is increased, thereby forming protection for the second component 102 and the third component 103 that are easily broken or damaged, and optimizing the anti-drop and anti-screen performance of the display device 100.

[0118] In some embodiments, as shown in FIG. 7 , the thickness d4 of the first component 101 is greater than the thickness d5 of the second component 102 , and greater than the thickness d6 of the third component 103 .

[0119] For example, the thickness d5 of the second component 102 and the thickness d6 of the third component 103 may be substantially the same.

[0120] By setting the thickness d4 of the first component 101 to be greater than the thickness d5 of the second component 102 and the thickness d6 of the third component 103, when the first component 101 is subjected to force during a fall (for example, the first component 101 falls to the ground), the path for the external force to be transmitted from the first sub-shell N1 to the first sub-screen M1 can be increased, thereby reducing the risk of the external force being transmitted from the first sub-shell N1 to the first sub-screen M1, causing the first sub-screen M1 to be broken, and improving the protection capability of the first sub-screen M1. That is, when the force position is transferred to the first component 101 (that is, the left and right boundaries of the aforementioned first component 101 are relatively prominent), the thicker first component 101 has higher anti-fall and anti-screen shattering capabilities.

[0121] In some embodiments, the weight of the first component 101 is greater than the weight of the second component 102 , and greater than the weight of the third component 103 .

[0122] By setting the weight of the first component 101 to be heavier, the probability of the first component 101 falling downward (for example, on the ground) can be increased after the display device 100 in the folded state falls, thereby further transferring the force position to the first component 101, improving the protection capability of the fragile screen and the easily damaged second component 102 and third component 103, further improving the reliability of the display device 100, and extending its service life.

[0123] In some embodiments, the hardness of the first component 101 is greater than the hardness of the second component 102 , and greater than the hardness of the third component 103 .

[0124] By setting the hardness of the first component 101 to be higher and improving the protective capability of the first component 101, it is possible to prevent the first component 101, which has a more protruding side and a higher probability of landing, from being damaged after the display device 100 in the folded state falls, thereby further improving the protection capability of the fragile screen and the easily damaged second component 102 and third component 103, further improving the reliability of the display device 100 and extending its service life.

[0125] In some embodiments, as shown in FIG8 , the display device 100 further includes a communication component 60 . Referring to FIG8 , the communication component 60 is disposed in the first component 101 and at an end of the first component 101 away from the first connecting portion 104 .

[0126] Exemplarily, the communication component 60 can be disposed in a receiving cavity surrounded by the first sub-shell N1, the first middle frame 10 and the first sub-screen M1.

[0127] Exemplarily, the communication component 60 may include an antenna, or may include a radio frequency component or other structure required to communicate with the outside world.

[0128] It can be understood that the aforementioned “end portion of the first component 101 away from the first connecting portion 104 ” refers to the portion of the first component 101 at the position where the side edge away from the first connecting portion 104 is located.

[0129] For example, referring to FIG. 7 , the communication component 60 may be disposed in a portion of the first component portion 101 that exceeds the second connection portion 105 (when the display device 100 is in the folded state).

[0130] By arranging the communication component 60 in the first component 101 and at the end of the first component 101 away from the first connecting portion 104, when the display device 100 is in the folded state, the portion of the first component 101 where the communication component 60 is arranged protrudes from the second component 102 and the third component 103, thereby avoiding the second component 102 and the third component 103 from blocking the signal transmission path of the communication component 60, and similarly avoiding the second sub-screen M2 and the third sub-screen M3 corresponding to the second component 102 and the third component 103 from blocking the signal transmission path of the communication component 60, thereby effectively improving the signal transmission effect of the communication component 60.

[0131] For example, referring to Figure 7, when the display device 100 is in a folded state and the first component 101 and the second component 102 are folded inward (that is, the first sub-screen M1 and the second sub-screen M2 are arranged in contact with each other), the fifth sub-screen M5 is arranged to avoid the communication component 60, that is, the part of the first component 101 where the communication component 60 is arranged protrudes from the side of the fifth sub-screen M5 away from the first connecting portion 104 in a direction away from the first connecting portion 104, thereby avoiding the fifth sub-screen M5 blocking the signal transmission path of the communication component 60.

[0132] FIG9 is another side view of the display device 100 provided in an embodiment of the present application in a folded state.

[0133] In some embodiments, as shown in FIG. 9 , the display device 100 provided in the embodiment of the present application may further include at least one third connection portion H3 , in which two third connection portions H3 (including H31 and H32 ) are used as an example.

[0134] 9 , the display device 100 may include a plurality of second components 102 , and the display screen M includes a plurality of second sub-screens M2 , with one side of each second component 102 correspondingly provided with a second sub-screen M2 .

[0135] Exemplarily, referring to FIG. 9 , the sides of the plurality of second components 102 are sequentially connected and coupled in the second direction Y. As shown in FIG.

[0136] Referring to Figure 9, two adjacent second components 102 are rotatably connected via the third connection portion H3. That is, the two adjacent second components 102 can move toward or away from each other via the third connection portion H3, thereby allowing the two second sub-screens M2 corresponding to the two second components 102 to be unfolded or folded.

[0137] 9 , the first component 101 is connected to the second component 102 closest to the first component 101 via a first connection portion 104 , and the third component 103 is connected to the second component 102 closest to the third component 103 via a second connection portion 105 .

[0138] By providing a plurality of second component parts 102, multi-screen folding of the display device 100 can be achieved (only five-screen folding is used as an example in FIG9 ), thereby further increasing the display size of the display device 100 in full-screen display, or further reducing the size of the display device 100 after folding, thereby improving portability.

[0139] For example, referring to FIG. 9 , the number of the plurality of second components 102 is odd.

[0140] In this embodiment, for example, referring to FIG. 9 , when the display screen M is folded, the two second sub-screens M2 corresponding to the two second components 102 closest to the first component 101, among the multiple second components 102, are arranged away from each other, while the two second sub-screens M2 corresponding to the two second components 102 closest to the third component 103 are arranged close to each other. That is, when the display device 100 is in the folded state, the odd number of second components 102 allows the third sub-screen M1 to be located on the outer surface of the display device 100, thereby facilitating the display device 100 to display a small-sized screen in the folded state.

[0141] Exemplarily, the number of the plurality of second component parts 102 can also be an even number (not shown in the figure), so that after the display device 100 is folded, the third sub-screen M3 can also be folded on the inside (that is, not located on the outer surface), and the third component part 103 can be unfolded to expose the third sub-screen M3 when display is needed, thereby further improving the anti-fall and anti-shattering capabilities of the display device 100 in the folded state.

[0142] For example, in other embodiments, referring to FIG9 , when the display device 100 is in the folded state, the orthographic projection Q2 of the boundary of the third connection portion H3 located on the same side as the second connection portion 102 away from the first connection portion 104 on the reference plane P (refer to FIG9 , located at the same position as Q2 in the aforementioned embodiment) is closer to the orthographic projection of the first connection portion 104 on the reference plane P relative to the orthographic projection Q1 of the boundary of the first component 101 away from the first connection portion 104 on the reference plane P (refer to FIG9 , located at the same position as Q1 in the aforementioned embodiment), and the orthographic projection Q3 of the boundary of the third connection portion H3 located on the same side as the first connection portion 104 away from the second connection portion 105 on the reference plane P (refer to FIG9 , located at the same position as Q3 in the aforementioned embodiment) is closer to the orthographic projection of the second connection portion 105 on the reference plane P relative to the orthographic projection Q4 of the boundary of the first connection portion 104 away from the second connection portion 105 on the reference plane P (refer to FIG9 , located at the same position as Q4 in the aforementioned embodiment).

[0143] That is, the connection position of the two adjacent second component parts 102 (i.e., the third connection part H3) is also retracted relative to the side of the first component part 101, thereby forming a protection for the thinner second component part 102, avoiding damage to the second component part 102 or avoiding the part of the display screen M corresponding to the second component part 102 (i.e., the second sub-screen M2), as well as the part of the display screen M corresponding to the third connection part H3 from being broken.

[0144] It can be understood that when the display device 100 includes multiple second components 102, similar to the aforementioned embodiment, the left and right sides of the first component 101 can be made to protrude from the second component 102 and the third component 103 by setting the relative sizes of the first middle frame 10, the second middle frame 20 and the third middle frame 30. For details, please refer to the aforementioned embodiment and will not be repeated here.

[0145] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
