Description

Technical Field

[0001] This application relates to the field of foldable display technology, and in particular to a foldable screen support mechanism and display device. Background Technology

[0002] As electronic display devices become thinner, lighter, and more flexible, foldable flexible displays are increasingly being used in various terminal devices. Currently, most mainstream flexible foldable display devices on the market use traditional hinge mechanisms to achieve the folding and unfolding functions of the flexible display, which can meet the basic functional requirements of folding and unfolding display devices.

[0003] However, traditional hinge mechanisms have significant technical defects in practical applications. When a flexible display unfolds from a folded state to a flat state, due to the limitations of the hinge's mechanical structure, the bending position of the flexible display usually exhibits obvious unevenness. This leads to problems such as distorted display images and reduced touch operation accuracy, negatively impacting the user experience. Summary of the Invention

[0004] The main purpose of this application is to propose a folding screen support mechanism, which aims to solve the technical problems that the current folding and unfolding operation of flexible displays relies on hinge mechanisms, and the bending position of flexible displays usually shows obvious unevenness, resulting in screen distortion and reduced touch operation accuracy.

[0005] To achieve the above objectives, the foldable screen support mechanism proposed in this application includes: The base is used to embed the flexible display screen inside; A support member is movably connected to the base; A sensing and control unit is mounted on the base; An actuation component is provided, which is connected to the support member and electrically connected to the sensing control unit. When the sensing control unit detects that the flexible display screen in the folded state has been unfolded, the sensing control unit sends an unfolding signal to the actuation component. Upon receiving the unfolding signal, the actuation component drives the support member from the retracted state to the unfolded state, so as to support the unfolded flexible display screen through the support member.

[0006] In one embodiment, the support member is configured as a support arm, which is rotatably connected to the base; the actuation component includes an elastic member and a magnetic member, one end of the elastic member is connected to the base, the other end of the elastic member is connected to the support arm, and the magnetic member is disposed on the support arm; the base is provided with an electromagnetic attraction member, which is electrically connected to the sensing control unit. When the flexible display screen is in a folded state, the electromagnetic attractor and the magnetic component are attracted together, and the elastic component is in a compressed state. After receiving the unfolding signal, the electromagnetic attractor loses its magnetism, causing the elastic component to release its elastic potential energy and drive the support arm to rotate to the unfolded state.

[0007] In one embodiment, a first end of the support arm is rotatably connected to the base, and the magnetic element is disposed at a second end of the support arm; When the support arm is rotated to the unfolded state, the magnetic element of one of the support arms is used to attract the magnetic element of the other support arm.

[0008] In one embodiment, the base is provided with a limiting part; when the support arm rotates in the first direction to the unfolded state, the limiting part abuts against the support arm to prevent the support arm from continuing to rotate in the first direction and to keep the elastic member in a compressed state.

[0009] In one embodiment, the base has a protruding structure, and a first inclined portion and a second inclined portion are formed on opposite sides of the protruding structure, respectively; the support arm includes at least a first arm body and a second arm body, both the first arm body and the second arm body are provided with the magnetic element, and the first end of the first arm body and the first end of the second arm body are rotatably connected to the end of the protruding structure; When the electromagnetic attracting component and the magnetic component are attracted, the second end of the first arm body is attached to the first inclined portion, and the second end of the second arm body is attached to the second inclined portion.

[0010] In one embodiment, the folding screen support mechanism further includes a pressure sensing device, which is electrically connected to the sensing control unit and is used to detect the compressive force exerted on the support arm in the unfolded state. When the compressive force exceeds a preset pressure threshold, the sensing and control unit is used to alternately send a storage signal and an unfolding signal to the electromagnetic attractor; after receiving the storage signal, the electromagnetic attractor is energized, causing the electromagnetic attractor to attract the magnetic component, thereby driving the support arm to overcome the elastic force of the elastic component and rotate to the storage state.

[0011] In one embodiment, the sensing control unit includes a tag recognition module and a main control module. The tag recognition module has a recognition area, and the tag recognition module is electrically connected to the main control module. The main control module is electrically connected to the actuation component. The flexible display screen includes a tag instruction layer; during the unfolding process of the flexible display screen, the coverage area of ​​the tag instruction layer in the recognition area gradually increases; the tag recognition module is used to send a recognition completion signal to the main control module when the coverage area reaches a preset recognition condition; the main control module is used to send the unfolding signal to the actuation component after receiving the recognition completion signal.

[0012] This application also proposes a display device, which includes a flexible display screen and a folding screen support mechanism as described above.

[0013] In one embodiment, the flexible display screen includes a flexible screen body, a first elastic layer, a second elastic layer, and at least two electronic component layers; the at least two electronic component layers are sandwiched between the first elastic layer and the second elastic layer, and the gap between the at least two electronic component layers forms a folding space; the flexible screen body is disposed on the side of the first elastic layer facing away from the second elastic layer. The display device includes at least two folding screen support mechanisms, which are arranged at intervals in the folding space; the support member of each folding screen support mechanism is used to support the first elastic layer and / or the second elastic layer in the unfolded state.

[0014] In one embodiment, the support member is configured as a support arm, the first end of the support arm is rotatably connected to the base of the folding screen support mechanism, and the second end of the support arm is provided with a magnetic element; When the support arm of each of the folding screen support mechanisms is rotated to the unfolded state, the magnetic element of each of the folding screen support mechanisms is used to attract the magnetic element of the adjacent folding screen support mechanism.

[0015] The foldable screen support mechanism proposed in this application can replace the traditional hinge mechanism to realize the folding and unfolding operation of the flexible display screen. When the flexible display screen is in the folded state, the support member is in a retracted state relative to the base and does not contact the functional film layer in the flexible display screen, so as to avoid interfering with the unfolding action of the flexible display screen. When the flexible display screen is unfolded, the sensing control unit continuously detects the unfolding state of the flexible display screen. When the sensing control unit determines that the flexible display screen has been fully unfolded through the corresponding detection data, the sensing control unit will send an unfolding signal to the actuation component to trigger the actuation component to drive each support member in the retracted state to unfold relative to the base. When all the support members are moved to the unfolded state relative to the base under the drive of the actuation component, the support members will fit with the suspended part of the corresponding functional film layer. At this time, the support members can provide additional support for the folded position of the flexible display screen and can apply appropriate external force to the suspended part of the functional film layer. This can reduce the unevenness caused by wrinkles and collapses at the folded position, ensure the flatness of the folded position, thereby reducing problems such as display screen distortion and decreased touch operation accuracy, and improving the user experience.

[0023] As electronic display devices become thinner, lighter, and more flexible, foldable flexible displays are increasingly being used in various terminal devices. Currently, most mainstream flexible foldable display devices on the market use traditional hinge mechanisms to achieve the folding and unfolding functions of the flexible display, which can meet the basic functional requirements of folding and unfolding display devices.

[0024] However, traditional hinge mechanisms have significant technical defects in practical applications. When a flexible display unfolds from a folded state to a flat state, due to the limitations of the hinge's mechanical structure, the bending position of the flexible display usually exhibits obvious unevenness. This leads to problems such as distorted display images and reduced touch operation accuracy, negatively impacting the user experience.

[0025] To address the aforementioned issues, this application proposes a folding screen support mechanism that can replace the traditional hinge mechanism to achieve the folding and unfolding of the flexible display screen. When the flexible display screen is unfolded, the support component of the folding screen support mechanism unfolds accordingly and provides support for the flexible display screen, making the bending position of the flexible display screen flatter. This reduces problems such as screen distortion and decreased touch operation accuracy, thereby improving the user experience.

[0026] Please see Figures 1 to 3 and for reference Figures 4 to 6 An embodiment of this application provides a foldable screen support mechanism 1000, comprising: Base 1, used for embedding inside the flexible display screen 2000; Support member 2 is movably connected to base 1; The sensing and control unit 3 is mounted on the base 1; Actuation component 4 is connected to support member 2 and electrically connected to sensing control unit 3. When sensing control unit 3 detects that the flexible display screen 2000 in the folded state is unfolded, sensing control unit 3 sends an unfolding signal to actuation component 4. Actuation component 4 drives support member 2 from the folded state to the unfolded state after receiving the unfolding signal, so as to support the unfolded flexible display screen 2000 through support member 2.

[0027] In this embodiment, the flexible display screen 2000 may include multiple stacked functional film layers with flexible folding capabilities, such as a display layer, a component layer, and a structural layer for separation. The outermost layer is the display layer, which displays images and screens. Appropriate empty areas may be reserved between the functional film layers; these empty areas are called folding spaces 2600. The folding space 2600 is located at the folding position 2100 of the flexible display screen 2000, and the folding screen support mechanism 1000 may be correspondingly disposed within the folding space 2600. The base 1 of the folding screen support mechanism 1000 is a fixed part, which is used to fit against the suspended portions of the functional film layers in the folding space 2600 to form a basic support function. This prevents the folding space 2600 from collapsing without affecting the folding and unfolding operation of the flexible display screen 2000 at this position.

[0028] Multiple support members 2 can be configured and connected to the base 1 in any movable manner to move relative to the base 1 according to a preset motion trajectory. For example, the support member 2 can slide along a straight path on the base 1, or the support member 2 can be hinged to the base 1 around an axis, which is not limited here. When the support member 2 is in the retracted state relative to the base 1, the support member 2 can be attached to the surface of the base 1 and does not contact the functional film layer in the flexible display screen 2000, so as to avoid interference with the folding and unfolding operation of the flexible display screen 2000. When the support member 2 moves to the unfolded state relative to the base 1, the support member 2 will be attached to the suspended part of the functional film layer in the folding space 2600. In this way, it can provide additional support for the folding position 2100 of the flexible display screen 2000 when the flexible display screen 2000 is unfolded, and can apply appropriate external force to the suspended part of the functional film layer. This can reduce the unevenness of the folding position 2100 caused by wrinkles and collapses, and ensure the flatness of the folding position 2100.

[0029] The sensing control unit 3 can be housed inside the base 1. The sensing control unit 3 may include sensors and a controller. Since the shape, distance, pressure, and other parameters of the corresponding parts of the flexible display screen 2000 differ between the folded and unfolded states, the sensors can identify and detect the movement state of the flexible display screen 2000 based on these differences through image recognition, distance detection, pressure detection, and other means, to automatically determine whether the flexible display screen 2000 is unfolded. The controller can be a control chip with basic functions such as data storage, signal input / output, numerical comparison, and logical judgment, such as an MCU (Microcontroller Unit). When the detection data acquired by the sensor meets the preset parameter conditions stored in the controller, the controller determines that the flexible display screen 2000 is in the unfolded state. At this time, the controller can send an unfolding signal to the actuation component 4 in the form of an electrical signal to trigger the actuation component 4 to perform the corresponding operation.

[0030] The actuation component 4 can be any device or combination thereof with a driving function, such as a motor, cylinder, spring, magnet, etc., to drive the support member 2. No limitation is made here. Upon receiving an unfolding signal from the sensing control unit 3, the actuation component 4 can automatically drive the support member 2 from its retracted state to its unfolded state, thereby providing additional support to the folding position 2100 of the unfolded flexible display screen 2000.

[0031] In this embodiment, the sensor control unit 3, actuation component 4, and other functional modules that require energy to drive can all be powered by the power supply component 7 built into the base 1 to ensure their stable operation.

[0032] Based on the above settings, the complete working process of the folding screen support mechanism 1000 during the unfolding of the flexible display screen 2000 is as follows: like Figure 1 and Figure 5 As shown, the flexible display screen 2000 is in a folded state, at which time the support member 2 is also in a retracted state relative to the base 1. The support member 2 can fit against the surface of the base 1 without contacting the functional film layer in the flexible display screen 2000, so as to avoid interfering with the unfolding action of the flexible display screen 2000. When the flexible display screen 2000 unfolds, the sensing control unit 3 continuously detects the unfolding state of the flexible display screen 2000. When the sensing control unit 3 determines through the corresponding detection data that the flexible display screen 2000 has been fully unfolded to the desired position... Figure 4 and Figure 6 In the state shown, the sensing control unit 3 will send an unfolding signal to the actuation component 4 to trigger the actuation component 4 to drive each support member 2 in the retracted state to unfold relative to the base 1 as shown. Figure 2 The state shown; such as Figure 3As shown, when all the support members 2 are moved to the unfolded state relative to the base 1 under the drive of the actuation component 4, the support members 2 will fit against the suspended part of the corresponding functional film layer. At this time, the support members 2 can provide additional support for the folded position 2100 of the flexible display screen 2000 and apply appropriate external force to the suspended part of the functional film layer. This can reduce the unevenness caused by wrinkles and collapses at the folded position 2100, ensure the flatness of the folded position 2100, thereby reducing problems such as screen distortion and decreased touch operation accuracy, and improving the user experience.

[0033] In one embodiment, refer to Figures 1 to 3 The support member 2 is configured as a support arm 21, which is rotatably connected to the base 1; the actuation component 4 includes an elastic member 41 and a magnetic member 42, one end of the elastic member 41 is connected to the base 1, the other end of the elastic member 41 is connected to the support arm 21, and the magnetic member 42 is disposed on the support arm 21; the base 1 is provided with an electromagnetic attraction member 5, which is electrically connected to the sensing control unit 3. When the flexible display screen 2000 is in the folded state, the electromagnetic attractor 5 and the magnetic component 42 are attracted together, and the elastic component 41 is in the compressed state. After receiving the unfolding signal, the electromagnetic attractor 5 loses its magnetism, causing the elastic component 41 to release its elastic potential energy and drive the support arm 21 to rotate to the unfolded state.

[0034] In this embodiment, one end of the support arm 21 can be rotatably connected to the base 1 via a pivot 6 in a hinged or other manner.

[0035] The elastic element 41 can be a spring, elastic colloid, etc. One end of the elastic element 41 is connected to the base 1, and the other end of the elastic element 41 is connected to the side of the support arm 21 facing the base 1.

[0036] The magnetic component 42 can be a magnet with a fixing and adsorption function, and the magnetic component 42 is located on the side of the support arm 21 facing the base 1. The electromagnetic attraction component 5 can be an electromagnet; when the electromagnetic attraction component 5 is energized, it is in an excited state, and at this time, the electromagnetic attraction component 5 can generate a magnetic attraction effect on the magnetic component 42; when the electromagnetic attraction component 5 is de-energized, it is in a demagnetized state, and at this time, the electromagnetic attraction component 5 cannot generate a magnetic attraction effect on the magnetic component 42.

[0037] like Figure 1 and Figure 5As shown, when the flexible display screen 2000 is in a folded state, the electromagnetic attractor 5 is continuously energized and in an excited state. The electromagnetic attractor 5 will generate a magnetic attraction to the magnetic component 42. This magnetic attraction force is greater than the elastic force applied to the support arm 21 by the elastic component 41, which can ensure that the electromagnetic attractor 5 and the magnetic component 42 are stably attracted, so that the support arm 21 is attached to the base 1 and in a retracted state. The elastic component 41 between the support arm 21 and the base 1 is squeezed and in a compressed state. Figure 2 , Figure 3 and Figure 6 As shown, during the unfolding process of the flexible display screen 2000, when the sensing control unit 3 detects that the flexible display screen 2000 has been fully unfolded, the sensing control unit 3 sends an unfolding signal to the electromagnetic attractor 5. This unfolding signal can trigger the corresponding switching element to demagnetize the electromagnetic attractor 5. At this time, the elastic element 41 in the compressed state will release its elastic potential energy, driving the support arm 21 to rotate in the direction away from the base 1 to the unfolded state. Thus, the unfolded support arm 21 can provide support for the folded position 2100 of the flexible display screen 2000. Subsequently, when the flexible display screen 2000 is folded again, the electromagnetic attractor 5 can be energized and re-enter the energized state. The magnetic attraction force between the electromagnetic attractor 5 and the magnetic element 42 will drive the support arm 21 to overcome the elastic force of the elastic element 41 and rotate back to the retracted state.

[0038] When multiple support arms 21 are provided, an elastic element 41, a magnetic element 42 and an electromagnetic attraction element 5 can be provided for each support arm 21 respectively, so that through the coordinated cooperation between each set of elastic elements 41, magnetic elements 42 and electromagnetic attraction elements 5, each support arm 21 can be driven to unfold relative to the base 1 when the flexible display screen 2000 is unfolded.

[0039] Based on the form of the actuation component 4 in this embodiment, the support arm 21 can be driven in a simple, low-cost, and low-energy-consumption manner without setting up too many power sources, ensuring the stability of the movement of the support arm 21 along the preset path, and maintaining the rationality of the overall structural layout of the folding screen support mechanism 1000.

[0040] Preferably, refer to Figures 1 to 3 A first magnet 8 can be installed on the support arm 21 near the rotating shaft 6, and a second magnet 9 can be installed on the base 1 corresponding to the first magnet 8. The first magnet 8 and the second magnet 9 can be magnetically attracted. The magnetic attraction between the first magnet 8 and the second magnet 9 can be used to assist and compensate for the magnetic attraction between the electromagnetic attractor 5 and the magnetic component 42, so that when the electromagnetic attractor 5 is re-energized and the support arm 21 rotates in the direction close to the base 1, the support arm 21 can overcome the gradually increasing elastic force and stably adhere to the base 1.

[0041] In one embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The first end of the support arm 21 is rotatably connected to the base 1, and the magnetic element 42 is disposed at the second end of the support arm 21. When the support arm 21 is rotated to the unfolded state, the magnetic element 42 of one support arm 21 is used to attract the magnetic element 42 of the other support arm 21.

[0042] In this embodiment, taking two folding screen support mechanisms 1000 as an example, the two folding screen support mechanisms 1000 are arranged side by side in the folding space 2600 at the folding position 2100 of the flexible display screen 2000. When the flexible display screen 2000 is fully unfolded, the support arms 21 of the two folding screen support mechanisms 1000 rotate to the unfolded state and provide support for the folding position 2100. At this time, the second end of the support arm 21 of one folding screen support mechanism 1000 contacts the second end of the support arm 21 of the other folding screen support mechanism 1000, and the two magnetic components 42 provided on the two support arms 21 magnetically attract each other. In this way, the two support arms 21 are connected by magnetic attraction to form a stable support structure. This support structure can provide stable support for the folding position 2100 over a long span, which can reduce the unstable swing of the end of the support arm 21, thereby further improving the support stability of the support arm 21 and the flatness of the flexible display screen 2000 after unfolding.

[0043] When the number of foldable screen support mechanisms 1000 is set to two or more, multiple foldable screen support mechanisms 1000 can be configured as follows: Figures 5 to 7 As shown, the magnetic elements 42 on the support arm 21 of each folding screen support mechanism 1000 are arranged at intervals within the folding space 2600 at the folding position 2100 of the flexible display screen 2000. Each magnetic element 42 can be magnetically attracted to the magnetic element 42 on the support arm 21 of an adjacent folding screen support mechanism 1000, thereby connecting multiple support arms 21 to form a structure as shown. Figure 7 The continuous support structure shown provides continuous support for the folding position 2100 with a large span, ensuring the flatness of the folding position 2100.

[0044] Based on the scheme of this embodiment, the magnetic component 42 can be used to maintain the storage state of the support arm 21 and can also be used to connect adjacent support arms 21 without the need to set up a separate connection structure on the support arm 21. This maximizes the utilization of the corresponding functional components in the folding screen support mechanism 1000 while ensuring the simplicity of the overall structure.

[0045] In one embodiment, refer to Figures 1 to 3The base 1 is provided with a limiting part 11; when the support arm 21 rotates to the unfolded state in the first direction, the limiting part 11 abuts against the support arm 21 to prevent the support arm 21 from continuing to rotate in the first direction and to keep the elastic member 41 in a compressed state.

[0046] Specifically, the limiting part 11 can be directly disposed on the base 1, or it can be indirectly disposed on other components fixed to the base 1. For example, as shown in the figure... Figures 1 to 3 As shown, a rotating shaft 6 is provided on the base 1, and the first end of the support arm 21 is rotatably engaged with the rotating shaft 6. The limiting part 11 can be provided on the cylindrical surface of the rotating shaft 6 in the form of a boss, and the first end of the support arm 21 can also be provided with a corresponding boss or other engaging part 211. After the flexible display screen 2000 is unfolded, when the support arm 21 rotates to a preset angle in the direction away from the base 1 (i.e., the first direction), the engaging part 211 on the support arm 21 abuts against the limiting part 11 on the rotating shaft 6, and the limiting part 11 will prevent the support arm 21 from continuing to rotate in the first direction. At this time, the elastic element 41 is still not fully reset and is in a compressed state. Under the elastic force applied by the elastic element 41, the support arm 21 will remain tightly attached to the limiting part 11. Compared with the form where the elastic element 41 is fully reset, this solution can retain an appropriate elastic force through the limiting action, thereby ensuring the positional stability of the support arm 21, and thus further improving the support stability of the support arm 21 on the subsequent folding position 2100.

[0047] In one embodiment, refer to Figures 1 to 3 The base 1 has a protruding structure 12, and a first inclined portion 121 and a second inclined portion 122 are formed on opposite sides of the protruding structure 12, respectively; the support arm 21 includes at least a first arm body 21a and a second arm body 21b, both of which are provided with magnetic elements 42, and the first end of the first arm body 21a and the first end of the second arm body 21b are rotatably connected to the end of the protruding structure 12; When the electromagnetic attractor 5 and the magnetic component 42 are attracted, the second end of the first arm 21a is attached to the first inclined portion 121, and the second end of the second arm 21b is attached to the second inclined portion 122.

[0048] Specifically, with Figures 1 to 3 Taking the orientation shown as an example, both the upper and lower sides of the base 1 are provided with protruding structures 12. For the upper protruding structure 12, its left side slopes downwards to form a first inclined portion 121, and its right side slopes downwards to form a second inclined portion 122; the right end of the first arm 21a and the left end of the second arm 21b are rotatably connected to the highest point of the protruding structure 12 around the same pivot 6; the first arm 21a is correspondingly provided with an elastic element 41, a magnetic element 42, and an electromagnetic attraction element 5, and the second arm 21b is also correspondingly provided with an elastic element 41, a magnetic element 42, and an electromagnetic attraction element 5; as shown... Figure 1 As shown, when the first arm 21a and the second arm 21b are in the retracted state, the electromagnetic attracting component 5 and the magnetic component 42 are magnetically attracted. At this time, the first arm 21a is attached to the first inclined portion 121, and the second arm 21b is attached to the second inclined portion 122. The right end of the first arm 21a and the left end of the second arm 21b abut against the functional membrane layer above to form a basic support function; Figure 2 and Figure 3 As shown, when the first arm 21a and the second arm 21b extend upwards to a horizontal state under the action of the elastic member 41, the upper parts of the first arm 21a and the upper parts of the second arm 21b fully adhere to the functional film layer above, providing support for that part of the functional film layer. Similarly, for the lower protrusion structure 12, its left side slopes upwards to form a first inclined part 121, and its right side slopes upwards to form a second inclined part 122; the right end of the first arm 21a and the left end of the second arm 21b are rotatably connected to the lowest position of the protrusion structure 12 around the same pivot 6; the first arm 21a is correspondingly provided with an elastic member 41, a magnetic member 42, and an electromagnetic attraction member 5, and the second arm 21b is also correspondingly provided with an elastic member 41, a magnetic member 42, and an electromagnetic attraction member 5; as Figure 1 As shown, when the first arm 21a and the second arm 21b are in the retracted state, the electromagnetic attracting component 5 and the magnetic component 42 are magnetically attracted. At this time, the first arm 21a is attached to the first inclined portion 121, and the second arm 21b is attached to the second inclined portion 122. The right end of the first arm 21a and the left end of the second arm 21b abut against the functional membrane layer below to form a basic support function; Figure 2 and Figure 3 As shown, when the first arm 21a and the second arm 21b are extended downward to a horizontal state under the action of the elastic member 41, the lower part of the first arm 21a and the lower part of the second arm 21b are fully attached to the functional membrane layer below, which can provide support for this part of the functional membrane layer.

[0049] Based on the above configuration, two first arm bodies 21a and two second arm bodies 21b can be simultaneously mounted on a base 1, and the first arm bodies 21a and second arm bodies 21b can simultaneously support the functional membrane layers on the upper and lower sides of the base 1. Furthermore, when multiple folding screen support mechanisms 1000 are configured, as shown... Figure 6 and Figure 7When arranged at intervals along the left and right direction, for any two adjacent folding screen support mechanisms 1000, with both the first arm 21a and the second arm 21b unfolded, the magnetic element 42 on the second arm 21b of the folding screen support mechanism 1000 on the left can magnetically attract the magnetic element 42 on the first arm 21a of the folding screen support mechanism 1000 on the right, thereby realizing the connection between the support arms 21 of the two adjacent folding screen support mechanisms 1000 and forming a continuous support effect on the flexible display screen 2000.

[0050] In one embodiment, refer to Figures 1 to 3 The folding screen support mechanism 1000 also includes a pressure sensing device (not shown in the figure), which is electrically connected to the sensing control unit 3. The pressure sensing device is used to detect the compressive force on the support arm 21 in the unfolded state. When the pressing force exceeds the preset pressure threshold, the sensing control unit 3 is used to alternately send a storage signal and an unfolding signal to the electromagnetic attractor 5; after receiving the storage signal, the electromagnetic attractor 5 is energized, causing the electromagnetic attractor 5 to attract the magnetic component 42, thereby driving the support arm 21 to overcome the elastic force of the elastic component 41 and rotate to the storage state.

[0051] Specifically, a pressure sensing device can be installed on the support arm 21, and a preset pressure threshold can be stored in the controller of the sensing control unit 3. When the support arm 21 is extended, if the sensing control unit 3 determines that the compressive force obtained by the pressure sensing device exceeds the preset pressure threshold, it indicates that the reaction force exerted by the flexible display screen 2000 on the support arm 21 is too large, and the support arm 21 and the flexible display screen 2000 are not in a good contact state. From this, it can be inferred that the flexible display screen 2000 may have unevenness such as arching, wrinkling, or curling. In this case, the sensing control unit 3 will be triggered to alternately send retraction and extension signals to the electromagnetic attraction component 5, causing the electromagnetic attraction component 5 to repeatedly switch between energized and de-energized states, thereby driving the support arm 21 to swing back and forth. During the swinging process, the support arm 21 can intermittently apply pressure to the parts of the flexible display screen 2000 with unevenness. The combined force, that is, the slapping and pushing action on the uneven parts of the flexible display screen 2000; during the repeated swinging operation of the support arm 21, the pressing force applied by the support arm 21 can gradually flatten the uneven parts of the flexible display screen 2000, and at this time the reaction force of the flexible display screen 2000 on the support arm 21 will also gradually decrease; when the pressing force obtained by the pressure sensing device is lower than the preset pressure threshold, it can be considered that the folded position 2100 of the flexible display screen 2000 has reached a flat state. At this time, the electromagnetic attraction 5 will remain in a demagnetized state, and the support arm 21 will stably press against the flexible display screen 2000 to maintain the current flat state of the unfolded flexible display screen 2000 through the support action.

[0052] Based on the above settings, pressure detection can be used to determine whether the flexible display screen 2000 is still uneven after unfolding, and the unevenness can be automatically eliminated by the reciprocating swing of the support arm 21, ensuring that the support arm 21 and the flexible display screen 2000 are in a moderate pressure contact state, thereby improving the flatness of the flexible display screen 2000 after unfolding.

[0053] In one embodiment, refer to Figures 1 to 3 and for reference Figures 5 to 7 The sensing control unit 3 includes a tag recognition module 31 and a main control module 32. The tag recognition module 31 has a recognition area. The tag recognition module 31 is electrically connected to the main control module 32, and the main control module 32 is electrically connected to the actuation component 4. The flexible display screen 2000 includes a tag instruction layer 2900; during the unfolding process of the flexible display screen 2000, the coverage area of ​​the tag instruction layer 2900 in the recognition area gradually increases; the tag recognition module 31 is used to send a recognition completion signal to the main control module 32 when the coverage area reaches the preset recognition conditions; the main control module 32 is used to send an unfolding signal to the actuation component 4 after receiving the recognition completion signal.

[0054] Specifically, the main control module 32 can be a control chip with basic functions such as data storage, signal input and output, numerical comparison, and logical judgment, such as an MCU (Microcontroller Unit).

[0055] The tag recognition module 31 can use magnetic sensors, capacitive sensors, etc. The recognition area refers to the effective sensing range of the tag recognition module 31. The tag instruction layer 2900 can be set as a thin film layer with recognizable physical characteristics, such as magnetic coating, patterned conductive layer, etc., so as to form a non-contact detection interaction with the tag recognition module 31.

[0056] The label recognition module 31 can be disposed inside the base 1; the label instruction layer 2900 can be sandwiched between other functional film layers of the flexible display screen 2000 and disposed at the folding position 2100 of the flexible display screen 2000; when the flexible display screen 2000 is in a folded state, the label instruction layer 2900 is bent into an arc-shaped structure. At this time, the label instruction layer 2900 is not fully displayed in the recognition area of ​​the label recognition module 31, that is, the coverage area of ​​the label instruction layer 2900 in the recognition area is small; as the flexible display screen 2000 gradually unfolds, the label instruction layer 2900 gradually unfolds from an arc-shaped structure into a planar structure. The coverage area of ​​the label instruction layer 2900 in the recognition area gradually increases; when the label instruction layer 2900 is fully unfolded, the label instruction layer 2900 will be fully displayed in the recognition area, that is, at this time the coverage area of ​​the label instruction layer 2900 in the recognition area has reached the preset recognition conditions of the label recognition module 31, and the label recognition module 31 can complete the reading of the label instruction layer 2900; after the reading is completed, the label recognition module 31 will send the recognition completion signal to the main control module 32 to trigger the main control module 32 to send the unfolding signal to the actuator 4 in the form of an electrical signal, thereby triggering the actuator 4 to drive the support member 2 to move to the unfolded state to support the flexible display screen 2000.

[0057] This embodiment achieves detection interaction between the tag instruction layer 2900 and the tag recognition module 31 through geometric changes in the tag instruction layer 2900. It can accurately identify and detect the unfolding state of the flexible display screen 2000 without contact, ensuring that the support component 2 is activated in time after the flexible display screen 2000 is fully unfolded. This non-contact detection method can avoid the interference and wear problems of traditional mechanical detection, and further simplify the structure, reduce costs, and is more conducive to mass production.

[0058] This application also provides a display device; please refer to [link / reference]. Figures 1 to 7 The display device includes a flexible display screen 2000 and a folding screen support mechanism 1000 in any of the above embodiments.

[0059] In this embodiment, the display device may include foldable terminal devices with display functions such as mobile phones and tablet computers. The flexible display screen 2000 is the core display component of the display device, and it together with the folding screen support mechanism 1000 constitutes the main body of the display device. The flexible display screen 2000 may include multiple stacked functional film layers with flexible folding function, such as display layer, component layer, and structural layer for separation; the outermost layer is the display layer, which is used to display images and screens; appropriate empty areas may be reserved between each functional film layer, which is called folding space 2600. The folding space 2600 is located at the folding position 2100 of the flexible display screen 2000, and the folding screen support mechanism 1000 may be correspondingly arranged within the folding space 2600.

[0060] For the specific structure of the folding screen support mechanism 1000, please refer to the description of the above embodiments. Since the display device in this embodiment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments. That is, the folding screen support mechanism 1000 can replace the traditional hinge mechanism to realize the folding and unfolding operation of the flexible display screen 2000; when the flexible display screen 2000 is in the folded state, the support member 2 is in a retracted state relative to the base 1 and does not contact the functional film layer in the flexible display screen 2000, so as to avoid interfering with the unfolding action of the flexible display screen 2000; when the flexible display screen 2000 is unfolded, the sensing control unit 3 continuously detects the unfolding state of the flexible display screen 2000; when the sensing control unit 3 determines through the corresponding detection data that the flexible display screen 2000 has unfolded... When fully unfolded, the sensing control unit 3 sends an unfolding signal to the actuation component 4 to trigger the actuation component 4 to drive each support member 2 in the retracted state to unfold relative to the base 1. When all the support members 2 are moved to the unfolded state relative to the base 1 under the drive of the actuation component 4, the support members 2 will fit against the suspended part of the corresponding functional film layer. At this time, the support members 2 can provide additional support for the folding position 2100 of the flexible display screen 2000 and can apply appropriate external force to the suspended part of the functional film layer. This can reduce the unevenness of the folding position 2100 caused by wrinkles and collapses, ensure the flatness of the folding position 2100, thereby reducing problems such as display screen distortion and decreased touch operation accuracy, and improving the user experience.

[0061] In one embodiment, refer to Figures 5 to 7The flexible display screen 2000 includes a flexible screen body 2200, a first elastic layer 2300, a second elastic layer 2400, and at least two electronic component layers 2500; the at least two electronic component layers 2500 are sandwiched between the first elastic layer 2300 and the second elastic layer 2400, and the gap between the at least two electronic component layers 2500 forms a folding space 2600; the flexible screen body 2200 is disposed on the side of the first elastic layer 2300 facing away from the second elastic layer 2400. The display device includes at least two folding screen support mechanisms 1000, which are arranged at intervals in the folding space 2600; the support member 2 of each folding screen support mechanism 1000 is used to support the first elastic layer 2300 and / or the second elastic layer 2400 in the unfolded state.

[0062] In this embodiment, the flexible display screen 2000 adopts a multi-layer composite stacked structure. Specifically, the flexible display screen 2000 includes a flexible screen body 2200, a first elastic layer 2300, a second elastic layer 2400, and at least two electronic component layers 2500. The first elastic layer 2300 and the second elastic layer 2400 can be made of elastic materials such as polyimide and silicone. The first elastic layer 2300 and the second elastic layer 2400 serve as the upper and lower substrates of the flexible display screen 2000, respectively. At least two electronic component layers 2500 are sandwiched between the first elastic layer 2300 and the second elastic layer 2400. The electronic component layers 2500 may include a driving circuit layer, a touch sensing layer, etc. The first elastic layer 2300 and the second elastic layer 2400 serve as protective carriers for the electronic component layers 2500. They can use their own elastic deformation capabilities to buffer the mechanical stress generated during folding and unfolding, avoiding problems such as breakage and poor contact of the corresponding components and modules in the electronic component layers 2500 due to bending.

[0063] The intervals between the electronic component layers 2500 are configured as folding spaces 2600, which provide an installation and movement area for the folding screen support mechanism 1000. The size of the folding space 2600 matches the shape of the folding screen support mechanism 1000, satisfying the deformation requirements of the flexible display screen 2000 when folded, and providing ample space for the folding screen support mechanism 1000 to be stored and unfolded. The flexible screen body 2200 is located on the side of the first elastic layer 2300 facing away from the second elastic layer 2400, serving as a visual display interface.

[0064] At least two folding screen support mechanisms 1000 are arranged at intervals in the aforementioned folding space 2600. The base 1 of each folding screen support mechanism 1000 is fixed to the inner wall of the folding space 2600 (i.e., the inner sidewall of the first elastic layer 2300 and the inner sidewall of the second elastic layer 2400). When the flexible display screen 2000 is in the folded state, the support member 2 is housed on the base 1, and the support member 2 remains in a non-contact state with the first elastic layer 2300 and the second elastic layer 2400 to avoid interference. When the flexible display screen 2000 is unfolded, the sensing control unit 3 triggers the actuation component 4, which drives the support member 2 to unfold, so that the end of the support member 2 fits against the inner sidewall of the first elastic layer 2300 and the inner sidewall of the second elastic layer 2400 to form rigid support for the first elastic layer 2300 and the second elastic layer 2400.

[0065] Based on the above configuration, the folding space 2600 formed between each electronic component layer 2500 is used as the installation area of ​​the folding screen support mechanism 1000. This avoids interference between the folding screen support mechanism 1000 and the electronic component layer 2500 and ensures a compact internal layout of the flexible display screen 2000. In addition, the multiple folding screen support mechanisms 1000 arranged at intervals can achieve an orderly layout within the folding space 2600, forming uniform multi-point rigid support when the flexible display screen 2000 is unfolded, ensuring the flatness of the flexible display screen 2000 after unfolding.

[0066] Preferably, refer to Figures 5 to 7 The flexible display screen 2000 also includes a sealing layer 2700, which is disposed between the folding space 2600 and the electronic component layer 2500. The sealing layer 2700 can enclose the folding space 2600, which can prevent external factors from adversely affecting the normal operation of the folding screen support mechanism 1000 in the folding space 2600, and can also prevent the folding screen support mechanism 1000 from interfering with the electronic component layer 2500.

[0067] Preferably, refer to Figures 5 to 7 The flexible display screen 2000 also includes a camera module 2800. The camera module 2800 is disposed on the side of the second elastic layer 2400 facing away from the first elastic layer 2300. The camera module 2800 can be electrically connected to the main control module 32 to convert the acquired optical image signal into an electrical signal and store it in the main control module 32 for subsequent use.

[0068] In one embodiment, refer to Figures 5 to 7 and for reference Figures 1 to 3 The support member 2 is configured as a support arm 21. The first end of the support arm 21 is rotatably connected to the base 1 of the folding screen support mechanism 1000, and the second end of the support arm 21 is provided with a magnetic element 42. When the support arm 21 of each folding screen support mechanism 1000 is rotated to the unfolded state, the magnetic element 42 of each folding screen support mechanism 1000 is used to attract with the magnetic element 42 of the adjacent folding screen support mechanism 1000.

[0069] In this embodiment, one end of the support arm 21 is rotatably connected to the base 1 via a hinge or other means through a pivot 6. The elastic element 41 can be a spring, elastic colloid, etc., with one end connected to the base 1 and the other end connected to the side of the support arm 21 facing the base 1. The magnetic element 42 can be a magnet with a fixing and adsorption function, and is disposed on the side of the support arm 21 facing the base 1. The electromagnetic attracting element 5 can be an electromagnet; when the electromagnetic attracting element 5 is energized, it is in an excited state, and at this time, it can magnetically attract the magnetic element 42; when the electromagnetic attracting element 5 is de-energized, it is in a demagnetized state, and at this time, it cannot magnetically attract the magnetic element 42.

[0070] like Figure 1 and Figure 5 As shown, when the flexible display screen 2000 is in a folded state, the electromagnetic attractor 5 is continuously energized and in an excited state. The electromagnetic attractor 5 will generate a magnetic attraction to the magnetic component 42. This magnetic attraction force is greater than the elastic force applied to the support arm 21 by the elastic component 41, which can ensure that the electromagnetic attractor 5 and the magnetic component 42 are stably attracted, so that the support arm 21 is attached to the base 1 and in a retracted state. The elastic component 41 between the support arm 21 and the base 1 is squeezed and in a compressed state. Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, during the unfolding process of the flexible display screen 2000, when the sensing control unit 3 detects that the flexible display screen 2000 has been fully unfolded, the sensing control unit 3 sends an unfolding signal to the electromagnetic attractor 5. This unfolding signal can trigger the corresponding switching element to demagnetize the electromagnetic attractor 5. At this time, the elastic element 41 in the compressed state will release its elastic potential energy, driving the support arm 21 to rotate in the direction away from the base 1 to the unfolded state. Thus, the unfolded support arm 21 can provide support for the folded position 2100 of the flexible display screen 2000. Subsequently, when the flexible display screen 2000 is folded again, the electromagnetic attractor 5 can be energized and re-enter the energized state. The magnetic attraction force between the electromagnetic attractor 5 and the magnetic element 42 will drive the support arm 21 to overcome the elastic force of the elastic element 41 and rotate back to the retracted state.

[0071] When multiple support arms 21 are provided, an elastic element 41, a magnetic element 42 and an electromagnetic attraction element 5 can be provided for each support arm 21 respectively, so that through the coordinated cooperation between each set of elastic elements 41, magnetic elements 42 and electromagnetic attraction elements 5, each support arm 21 can be driven to unfold relative to the base 1 when the flexible display screen 2000 is unfolded.

[0072] Furthermore, taking two folding screen support mechanisms 1000 as an example, the two folding screen support mechanisms 1000 are arranged side by side in the folding space 2600 at the folding position 2100 of the flexible display screen 2000. When the flexible display screen 2000 is fully unfolded, the support arms 21 of the two folding screen support mechanisms 1000 rotate to the unfolded state and provide support for the folding position 2100. At this time, the second end of the support arm 21 of one folding screen support mechanism 1000 contacts the second end of the support arm 21 of the other folding screen support mechanism 1000, and the two magnetic components 42 set on the two support arms 21 magnetically attract each other. In this way, the two support arms 21 can be connected by magnetic attraction to form a stable support structure. This support structure can provide stable support for the folding position 2100 over a long span, which can reduce the unstable swing of the end of the support arm 21, thereby further improving the support stability of the support arm 21 and the flatness of the flexible display screen 2000 after unfolding.

[0073] When the number of foldable screen support mechanisms 1000 is set to two or more, multiple foldable screen support mechanisms 1000 can be configured as follows: Figures 5 to 7 As shown, the magnetic elements 42 on the support arm 21 of each folding screen support mechanism 1000 are arranged at intervals within the folding space 2600 of the flexible display screen 2000. They can be magnetically attracted to the magnetic elements 42 on the support arm 21 of the adjacent folding screen support mechanism 1000 to connect multiple support arms 21 to form a continuous support structure. This provides continuous support for the folding position 2100 with a large span, ensuring the flatness of the folding position 2100.

[0074] Based on the scheme of this embodiment, the magnetic component 42 can be used to maintain the storage state of the support arm 21 and can also be used to connect adjacent support arms 21 without the need to set up a separate connection structure on the support arm 21. This maximizes the utilization of the corresponding functional components in the folding screen support mechanism 1000 while ensuring the simplicity of the overall structure.

[0075] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
