With the development of display technology, foldable display devices are available in the market, and can be roughly divided into two folds (including inward fold and outward fold), three folds (dual inward fold, dual outward fold, inward and outward fold), and the like according to the folding form. The display device with the folding function can switch the screen size in a folding mode. The screen is unfolded in the using state to obtain a larger display size so as to improve experience feeling, and the screen is folded in the non-using state to reduce the size of the screen so as to be convenient to carry.

Among them, the triple-folding type display device has the most remarkable change in the plane size of the screen in the folded and unfolded states, but has a problem of a large thickness in the folded state.

To solve the above problem, an embodiment of the first aspect of the present application provides a display module, which aims to solve the problem of the large thickness of the display device on the premise that the plane size of the screen can be significantly changed.

As shown in fig. 1 to 4, the display module 10 in the first embodiment of the present application includes a flexible screen 100, a first support member 200, a second support member 300, and a sliding roller 400. Specifically, the flexible screen 100 includes a first display portion 101 and a second display portion 102, the first display portion 101 is disposed on the first support member 200, the second display portion 102 is disposed on the second support member 300, and the first support member 200 is hinged to the second support member 300. At least part of the second display portion 102 is wound around the sliding scroll 400. Wherein the second display portion 102 has a deployed state and a stowed state, the slider roller 400 is configured to be movable in a first direction relative to the hinge of the first and second support members 200, 300 to switch the second display portion 102 between the deployed state and the stowed state.

It will be appreciated that second display portion 102 has an extended state and a stowed state, wherein the stowed state includes both a state in which the entire second display portion 102 is rolled up and a state in which the second display portion 102 is partially stowed. In addition, the first direction may be understood as a direction in which the second display portion is expanded or contracted, that is, the first direction is parallel to the surface of the second display portion 102 in the expanded state. When the sliding scroll 400 moves away from the hinge of the first support member 200 and the second support member 300, the flexible display screen 100 can be unfolded, and when the sliding scroll 400 moves close to the hinge of the first support member 200 and the second support member 300, the flexible display screen can be folded.

In the display module 10 of the embodiment of the present application, the first support member 200 and the second support member 300 are hinged, so that the first display portion 101 and the second display portion 102 can be unfolded or stored in a folding manner. Meanwhile, the display module 10 is further provided with a sliding scroll 400, at least a part of the second display part 102 is wound on the sliding scroll 400, and the second display part 102 of the flexible screen 100 can be switched between the unfolded state and the folded state through the movement of the sliding scroll 400. Therefore, in the display module 10 of the present embodiment, the flexible screen 100 is unfolded and stored in a combination of folding and sliding. Specifically, the flexible screen 100 is unfolded by first unfolding the first support member 200 relative to the second support member 300, thereby driving the first display portion 101 of the flexible screen 100 to be unfolded relative to the second display portion 102, and then moving the sliding roller 400 away from the hinge of the first support member 200 and the second support member 300 along the first direction until the second display portion 102 is converted into the unfolded state. At this time, the flexible screen 100 is completely unfolded, the display plane size of the flexible screen 100 is maximized, and the user can obtain the best screen use experience. The flexible screen 100 is stored in the following process: the sliding roller 400 is moved close to the hinge of the first support member 200 and the second support member 300 along the first direction until the second display portion 102 is converted into the retracted state (the second display portion 102 may be fully retracted or partially retracted), and then the first support member 200 is rotated relative to the second support member 300 to fold the first display portion 101 of the flexible screen 100 relative to the second display portion 102. At this time, the flexible screen 100 is completely accommodated, and the planar size of the flexible screen 100 is minimized.

Through the above process, no matter the process of unfolding or the process of accommodating the flexible screen 100, the plane size of the flexible screen 100 is changed twice, so that the display module 10 in the embodiment of the present application can significantly change the plane size of the flexible screen 100, and the display device has better screen use experience and better portability. In addition, the flexible screen 100 in the embodiment of the present application is unfolded and stored in a combination manner of folding and sliding rolling, in the sliding rolling manner, the stored portion of the flexible screen 100 is stored on the back surface of the second supporting member 300, and there is no need to additionally provide one supporting member, and if the three-folding unfolding and storing manner is adopted, at least three supporting members need to be provided, so that the display module 10 in the embodiment of the present application can have a thinner thickness compared with the three-folding manner. Therefore, the display module 10 in the embodiment of the present application can not only significantly change the planar size of the flexible screen 100, but also have a relatively thin thickness.

In addition, in the related art, the three-folding display device has two bendable regions on the flexible screen, and when one of the bendable regions is subjected to a shape change, a certain push-pull force is generated on the flexible screen, and the push-pull force acts on the other bendable region, so that the other bendable region is also subjected to a relatively obvious crease when being unfolded. In the display module in the embodiment of the application, the flexible screen 100 is unfolded and stored in a combination manner of folding and sliding rolling, and only one bendable part is arranged on the flexible screen 100, so that the problem of obvious crease caused by the influence of push-pull force among the plurality of bendable parts is solved.

In some embodiments, the second support member 300 is a retractable member, and the second display portion 102 switches between the deployed state and the stowed state as the second support member 300 is extended and retracted. That is, while the spool 400 moves in the first direction, the second support member 300 is simultaneously extended or retracted. Specifically, when the spool 400 moves away from the hinge of the first and second support members 200 and 300, the second support member 300 is extended; when the sliding reel 400 moves near the hinge of the first and second support members 200 and 300, the second support member 300 contracts. Thereby, it is possible to make the unfolded region of the second display part 102 supported by the second support member 300, thereby ensuring good rigidity of the unfolded region of the second display part 102.

In some embodiments, the second support member 300 includes a first mounting body 310, a second mounting body 320, and a first telescopic support 330. The first supporting member 200 is hinged to the first mounting body 310, the first telescopic support 330 is used for supporting the second display portion 102, and the first mounting body 310 and the second mounting body 320 are disposed on a side of the first telescopic support 330 away from the second display portion 102. Wherein the second mounting body 320 is configured to be interlocked with the sliding roller 400 to move in a first direction with respect to the first mounting body 310.

In this embodiment, the first telescopic support 330 is a structural member directly contacting the second display part 102 of the flexible screen 100 and providing a supporting force to the second display part 102, and the first and second mounting bodies 310 and 320 are used to support the first telescopic support 330, so as to enhance the structural strength and the structural rigidity of the first telescopic support 330. In addition, in the process that the sliding roller 400 moves away from the first installation body 310, the second display part 102 is gradually unfolded from the folded state, and the second installation body 320 is configured to be interlocked with the sliding roller 400, that is, the second installation body 320 moves along the first direction relative to the first installation body 310 along with the sliding roller 400, and the first telescopic support 330 is gradually extended along with the movement of the second installation body 320, so that the first telescopic support 330 can always support the unfolded region of the second display part 102, and the unfolded region of the second display part 102 has good rigidity.

Illustratively, the sliding roller 400 is connected with an end of the second mounting body 320 far from the first mounting body 310 so as to make the second mounting body 320 and the sliding roller 400 be linked.

In some embodiments, the flexible screen 100 includes a display panel 110 and a metal support layer 120 disposed on a backlight side of the display panel 110 (see fig. 5). As shown in fig. 3, the first telescopic support 330 includes a first section 331 and a second section 332 that are slidable relative to each other, the first section 331 is connected to the first mounting body 310, and the second section 332 is connected to the second mounting body 320. The first section 331 is bonded to the metal support layer 120, and the second section 332 is provided with a magnetic area for being matched with the metal support layer 120 for adsorption and fixation.

In this embodiment, as shown in fig. 6, the first telescopic support 330 includes a first section 331 and a second section 332 which are slidable relative to each other, and the telescopic function of the first telescopic support 330 in the first direction is achieved by arranging the first section 331 and the second section 332 to be slidable relative to each other. The first section 331 is connected to the first mounting body 310, and the second section 332 is connected to the second mounting body 320, so that the first telescopic support 330 can be extended and shortened by pushing and pulling the first mounting body 310 and the second mounting body 320. In addition, the first section 331 is bonded to the metal support layer 120 of the flexible screen 100, so that the first section 331 always keeps close contact with the metal support layer 120, which is beneficial to improving the flatness of the portion of the flexible screen 100 supported by the first section 331. The second section 332 is attracted to the metal support layer 120 through magnetism, so that, in the process that the second display portion 102 is gradually unfolded from the folded state, a part of the second display portion 102 supported by the second section 332 is tightly attached to the second section 332 under the action of an attraction force, so that the flatness can be improved, and meanwhile, the movement of the second display portion 102 is not hindered in the process of unfolding and folding.

In some embodiments, the magnetic region comprises a magnet embedded on the second section 332 or is a magnetic coating disposed on the surface of the second section 332.

In some embodiments, as shown in fig. 7, the second supporting member 300 further includes a second telescopic support 340, the first mounting body 310 and the second mounting body 320 are connected by the second telescopic support 340, and the second telescopic support 340 is located on a side of the first telescopic support 330 facing away from the second display part 102. Since the first mounting body 310 and the second mounting body 320 are connected not only by the first telescopic support 330 but also by the second telescopic support 340, the motion stability of the second mounting body 320 with respect to the first mounting body 310 can be improved to ensure that the second mounting body 320 can move strictly in the first direction without direction deviation.

In some embodiments, the second telescopic support 340 includes a third section 341 and a fourth section 342 that are slidable relative to each other, the third section 341 being connected with the first mounting body 310, and the fourth section 342 being connected with the second mounting body 320. The telescopic function of the second telescopic support 340 in the first direction is achieved by the way that the third section 341 and the fourth section 342 slide relatively. The third section 341 is connected to the first mounting body 310, and the fourth section 342 is connected to the second mounting body 320, so that the second telescopic supporting member 340 can be extended and shortened by pushing and pulling the first mounting body 310 and the second mounting body 320.

In some embodiments, when the second display portion 102 is in the retracted state, a portion of the second display portion 102 is wound around the sliding roller 400 and extends to the back of the display surface of the second display portion 102. The display module 10 further comprises a pulling assembly 500, wherein the pulling assembly 500 is connected with the retracted part of the second display part 102 to provide a pulling force F for tensioning the flexible screen 100. The display surface is a surface that generates a visible area when the display device is in a lit state.

In this embodiment, the pulling assembly 500 provides a pulling force F to the flexible screen 100, and under the pulling force F, the flexible screen 100 is beneficial to maintain the flatness of the flexible screen 100 no matter the flexible screen 100 is converted from the retracted state to the extended state or from the extended state to the retracted state, and the flexible screen 100 is prevented from being wrinkled and creased.

In some embodiments, the pulling assembly 500 may include a motor and a transmission member connected to the motor, the transmission member being connected to the second display part 102, and a stable pulling force may be provided to the flexible screen 100 through the motor and the transmission member, so that the flexible screen 100 maintains flatness. In addition, when the sliding roller 400 moves towards the direction close to the hinge joint of the first supporting member 200 and the second supporting member 300, the pulling force provided by the motor and the transmission component to the second display part 102 is matched, so that the second display part 102 can be conveniently retracted.

In other embodiments, the pulling assembly 500 includes at least one spring connected to the second display portion 102, so that the flexible screen 100 can be pulled with a lower cost spring, which is beneficial to reduce the manufacturing cost of the whole display module 10.

In some embodiments, the stowed portion of the second display 102 is fully wound on the spool 400 when the second display 102 is in the stowed state. In this embodiment, when in the retracted state, the retracted portion of the second display portion 102 is completely wound on the sliding roller 400, and the pulling assembly 500 connected to the second display portion 102 is not required to be disposed, so that the structure of the display module 10 is simpler, the space occupied by the display module 10 in the display device is saved, and the size of the display device is further reduced.

In some embodiments, the display module 10 further comprises a driving assembly (not shown) for driving the sliding roller 400 to move along the first direction relative to the hinge of the first support member 200 and the second support member 300. In this embodiment, the driving assembly is used to drive the sliding roller 400 to move in a first direction, so that the second display part 102 is switched between the unfolded state and the folded state by the movement of the sliding roller 400.

It will be appreciated that other structures may be required to accommodate the retraction or deployment of the second display portion 102 during movement of the slider axle 400 in the first direction.

For example, in the case where the pulling assembly 500 is provided, the second display portion 102 may be gradually unfolded as the sliding reel 400 moves away from the hinge of the first and second support members 200 and 300 in the first direction, and the pulling assembly 500 provides a pulling force to the first end of the second display portion 102 as the sliding reel 400 moves closer to the hinge of the first and second support members 200 and 300 in the first direction, whereby the second display portion 102 is gradually retracted as the sliding reel 400 moves.

As another example, the pulling member may not be provided when the stowed portion of the second display unit 102 is completely wound around the spool 400 in the stowed state. When the sliding scroll 400 moves away from the hinge of the first support member 200 and the second support member 300 in the first direction, the sliding scroll 400 rotates while moving, so that the portion of the second display portion 102 wound on the sliding scroll 400 is gradually released and unwound; when the sliding reel 400 moves in the first direction to approach the hinge between the first support member 200 and the second support member 300, the sliding reel 400 moves and rotates in the opposite direction, so that the second display part 102 is wound around the sliding reel 400 one turn, thereby collecting the second display part 102.

In some embodiments, as shown in fig. 8, the pulley shaft 400 includes an inner shaft 410 and an outer shaft 420 disposed on the inner shaft 410, the outer shaft 420 is configured to rotate relative to the inner shaft 410, the driving assembly is coupled to the inner shaft 410, and the second display portion 102 is supported on the outer shaft 420. In this embodiment, a drive assembly is coupled to the inner shaft 410 to drive the inner shaft 410 in a first direction to effect movement of the spool 400 in the first direction. In addition, the outer shaft 420 is sleeved on the inner shaft 410 and can rotate relative to the inner shaft 410, so that the outer shaft 420 can rotate along with the movement of the second display part 102 in the process of the form conversion of the second display part 102.

In some embodiments, as shown in fig. 1 and fig. 2, the flexible screen 100 further includes a bendable part 103, and the first display part 101 and the second display part 102 are connected by the bendable part 103. The first support member 200 and the second support member 300 may be connected by a hinge mechanism 600, thereby enabling articulation between the first support member 200 and the second support member 300.

An embodiment of the first aspect of the present application provides a display device, which includes the display module 10 in any of the above embodiments. The display device may be, for example, a product or a component having a display function, such as a display, a television, a digital camera, a mobile phone, a tablet computer, and a navigator.

In the display device in this embodiment of the application, by using the display module 10, the first supporting member 200 and the second supporting member 300 of the display module 10 are hinged, so that the first supporting member 200 and the second supporting member 300 can rotate relatively, and the first display portion 101 and the second display portion 102 of the flexible screen 100 can be driven to unfold or store in a folding manner. Meanwhile, the display module 10 is further provided with a sliding scroll 400, at least a part of the second display portion 102 is wound on the sliding scroll 400, and the second display portion 102 of the flexible screen 100 can be switched between the unfolded state and the folded state through the movement of the sliding scroll 400. Therefore, for the display module 10, the flexible screen 100 is unfolded and stored in a combination of folding and sliding. Specifically, the flexible screen 100 is unfolded by first unfolding the first support member 200 relative to the second support member 300, thereby driving the first display portion 101 of the flexible screen 100 to be unfolded relative to the second display portion 102, and then moving the sliding roller 400 away from the hinge of the first support member 200 and the second support member 300 along the first direction until the second display portion 102 is converted into the unfolded state. At this time, the flexible screen 100 is completely unfolded, the display plane size of the flexible screen 100 is maximized, and the user can obtain the best screen use experience. The flexible screen 100 is stored in the following process: the sliding roller 400 is moved close to the hinge of the first supporting member 200 and the second supporting member 300 along the first direction until the second display portion 102 is converted into the retracted state (the second display portion 102 may be fully retracted or partially retracted), and then the first supporting member 200 is rotated relative to the second supporting member 300 to fold the first display portion 101 of the flexible screen 100 relative to the second display portion 102. At this time, the flexible screen 100 is completely accommodated, and the planar size of the flexible screen 100 is minimized.

Through the above process, no matter the process of unfolding or the process of accommodating the flexible screen 100, the plane size of the flexible screen 100 is changed twice, so that the display module 10 in the embodiment of the present application can significantly change the plane size of the flexible screen 100, and the display device has better screen use experience and better portability. In addition, the flexible screen 100 in the embodiment of the present application is unfolded and stored in a manner of combining folding and sliding, and compared to the unfolding and storing manner of three-folding, in the sliding and rolling manner, the stored portion of the flexible screen 100 is stored at the back of the second supporting member 300, and there is no need to additionally provide a supporting member, and if the unfolding and storing manner of three-folding is adopted, at least three supporting members need to be provided, so compared to the three-folding manner, the display module 10 in the embodiment of the present application can have a thinner thickness. Therefore, the display module 10 in the embodiment of the present application can not only significantly change the planar size of the flexible screen 100, but also have a relatively thin thickness. Accordingly, the display device also has a thin thickness.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent application shall be subject to the appended claims.
