Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

It should be noted that the electronic device in the embodiment of the present application is mainly directed to an electronic device having a flexible screen structure, where the flexible screen is folded or unfolded in the electronic device in a telescopic manner. It can be understood that the electronic device in the present application may include a mobile phone, a tablet computer, a notebook computer, a wearable device, and other electronic devices having a flexible screen structure.

The flexible screen becomes the trend of the future whole machine design scheme, and the flexible screen mainly brings the advantage of improving the screen occupation ratio of the whole machine. By utilizing the characteristic that the flexible screen can be bent at will, the display panel can be designed into various shapes according to requirements, such as a display panel structure which can be curled or folded.

Based on this, the applicant found in research that the flexible screen has a limited area to be reduced by adopting the folding display panel structure, and the area of the flexible screen can be reduced by half by adopting the folding display panel structure. In addition, in the process of folding and unfolding, the folding position of the display panel can be folded for multiple times, which easily causes the failure of the display panel.

In order to solve the above problems, the technical solution of the embodiment of the present application is that by providing the flexible display device, the screen can have a smaller display area and occupy a smaller space when being folded, and can have a larger display area when being unfolded.

Referring to fig. 1 and fig. 2 in combination, fig. 1 is a partial structural schematic view of a flexible screen of an electronic device 1000 in some embodiments of the present application when folded, and fig. 2 is a partial structural schematic view of the flexible screen of the electronic device 1000 in some embodiments of the present application when unfolded. The electronic apparatus 1000 may generally include a flexible display device 100 and a housing 200. It is to be understood that the figures are merely exemplary to illustrate portions of the housing 200.

Specifically, the housing 200 has an accommodating space 201, and the flexible display device 100 is at least partially disposed in the accommodating space 201. As shown in fig. 1, when the flexible display device 100 is folded, the flexible display device 100 can be substantially accommodated in the accommodating space 201 of the housing 200, and the electronic apparatus has a small overall volume and is very portable. As shown in fig. 2, when the flexible display device 100 is unfolded, the flexible display device 100 can achieve a large-screen display effect to improve the user experience.

Referring to fig. 3 and 4 in combination, fig. 3 is a partial structural schematic view of the flexible display device 100 in some embodiments of the present disclosure when it is folded, fig. 4 is a partial structural schematic view of the flexible display device 100 in some embodiments of the present disclosure when it is unfolded, and the flexible display device 100 may generally include a flexible screen 10, a winding drum 20, and a driving mechanism 30. The housing 200 is connected to the driving mechanism 30 of the flexible display device, that is, the driving mechanism 30 is fixed to the housing 200, so that a stable driving force can be provided to the roll 20 of the flexible display device. The flexible screen 10 is driven by the driving mechanism 30 to be folded or unfolded by the winding drum 20.

Specifically, the winding drum 20 and the driving mechanism 30 are disposed on the same side of the flexible screen 10, i.e., the non-display surface of the flexible screen 10, and the flexible screen 10 may be wound around the outer sidewall of the winding drum 20. During the folding process of the flexible screen 10, a part of the flexible screen 10 and the winding drum 20 form a fixed connection structure, so that when the flexible screen 10 is folded, a part of the flexible screen 10 is wound on the outer side wall of the winding drum 20.

It is understood that the driving mechanism 30 may be a motor or a driver, and the embodiment of the present application is not particularly limited to the type of the driving mechanism 30. Specifically, the drive mechanism 30 according to the embodiment of the present application will be described by taking the stepping motor 30 as an example, and the stepping motor 30 is provided with a rotating shaft or a gear. The stepping motor 30 can drive the winding drum 20 to rotate through a rotating shaft, or can also be in meshed connection with the winding drum 20 through a gear to drive the winding drum 20 to rotate. Of course, in other embodiments, the drum 20 may be rotated by a belt drive. In the embodiment of the present application, the example that the stepping motor 30 drives the winding drum 20 to rotate through the engagement of the gear and the winding drum 20 is taken as an example.

Referring to fig. 5, fig. 5 is a schematic structural diagram of the flexible screen 10 in some embodiments of the present application when the flexible screen 10 is fully unfolded, and the flexible screen 10 may generally include a first display portion 11, a second display portion 12, and a third display portion 13. The first display portions 11 are substantially symmetrically disposed along a center line L of the flexible screen 10, that is, the first display portions 11 are substantially located in the middle of the flexible screen 10, wherein the center line L is a center line parallel to a relatively shorter side of the flexible screen 10. Specifically, when the flexible screen 10 is completely unfolded, the second display portions 12 are symmetrically disposed along the first display portion 11, that is, the second display portions 12 are symmetrically disposed along the central line L and distributed on two sides of the first display portion 11; the third display portions 13 are symmetrically disposed along the first display portion 11, that is, the third display portions 13 are symmetrically disposed along the central line L and distributed on two sides of the first display portion 11.

Further, the second display portion 12 is located between the first display portion 11 and the third display portion 13, that is, the second display portion 12 is close to the first display portion 11, and the third display portion 13 is far from the first display portion 11. In other words, the second display portion 12 is adjacent to the first display portion 11 on two opposite sides parallel to the center line L, and the third display portion 13 is not in contact with the first display portion 11; the second display unit 12 is provided between the first display unit 11 and the third display unit 13. In the folding process of the flexible screen 10, the first display portion 11 is preferentially bent to sink, then the second display portion 12 is bent to sink and is wound on the outer side wall of the winding drum 20 by the rotation of the winding drum 20, and finally the third display portion 13 is partially bent to sink and is wound on the outer side wall of the winding drum 200. After the flexible screen 10 is completely folded, a display area of the flexible screen 10 is formed by the third display part 13. It can be understood that, the unfolding process of the flexible screen 10 is opposite to the folding process, first, the third display portions 13 symmetrically arranged are far away from each other, then the second display portions 12 symmetrically arranged are far away from each other, and finally, the first display portions 11 symmetrically arranged are far away from each other, so as to realize the unfolding of the flexible screen 10.

The applicant finds in research that the flexible screen 10 can be folded and unfolded bidirectionally by starting to sink and bend from the middle part of the flexible screen 10, namely the first display area 11, so that the folding or unfolding time of the flexible screen 10 is saved, and the use experience of a user is improved. Therefore, in order to facilitate the flexible screen 10 to be capable of better sinking and bending in the furled initial state, the first suction attachment is disposed on the non-display surface of the first display portion 11 of the flexible screen 10.

Specifically, referring to fig. 6, fig. 6 is an enlarged schematic view of a portion of the structure in the area a in fig. 5, in which the flexible screen 10 includes a first display portion 11 disposed in the middle of the flexible screen, and a first suction attachment 111 is disposed on a non-display surface of the first display portion 11. During the folding process of the flexible screen 10, the first suction device 111 may be used to suck with the winding drum 20 to fix the first display portion 11 of the flexible screen 10, so that the second display portion 12 and a portion of the third display portion 13 of the flexible screen 10 are wound around the outer sidewall of the winding drum 20. It is understood that the non-display surface of the first display portion 11 may be a surface facing away from the display surface of the flexible screen, and may also be a side surface of the flexible screen, which is not specifically limited in this embodiment of the present application.

Further, the extending direction of the first suction attachment 111 is substantially parallel to the center line L, i.e., the first suction attachment 111 may have a bar shape. Specifically, the first suction device 111 may be formed by arranging a plurality of spaced apart strip-shaped suction members, and the arrangement direction of the strip-shaped suction members is substantially perpendicular to the center line L. The first suction fittings 111 are arranged at intervals, so that when the first suction fittings 111 are fixed with the winding drum 20, the phenomenon that the flexible screen at the position of the first display part 11 is folded and dead can be avoided.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

Referring to fig. 7, fig. 7 is a schematic structural view of the drum 20 according to some embodiments of the present disclosure, and the drum 20 generally includes a side wall 21 and a drum gear 22 disposed at an end of the side wall 21. Wherein the spool gear 22 is adapted to cooperate with a gear of the driving mechanism 30 to rotate the spool 20 under the driving of the driving mechanism 30. It is understood that the drum gear 22 may be disposed at one end of the side wall 21, and the drum gears 22 may also be disposed at both ends of the side wall 21, which is not particularly limited in the embodiments of the present application.

Further, the winding drum 20 may be a substantially hollow cylindrical structure, that is, the winding drum 20 has a receiving cavity 23, the side wall 21 is enclosed to form the receiving cavity 23, and the receiving cavity 23 receives the first display portion 11 of the flexible screen 10 during the folding process of the flexible screen 10. The sidewall of the winding drum 20 is provided with a second suction member 211, and the second suction member 211 is used for sucking the first suction member 111 to fix the first display part 11 of the flexible screen 10 to the sidewall of the winding drum 20 when the winding drum rotates.

The inner side wall of the winding drum 20 is provided with a second adsorption part 211, i.e. one side of the side wall 21 close to the accommodating cavity 23 is provided with the second adsorption part 211. It can be understood that the second suction member 211 is used for sucking the first suction member 111, that is, the second suction member 211 and the first suction member 111 form a suction connection relationship to fix the first display portion 11 of the flexible screen 10 to the inner side wall of the winding drum 20 when the winding drum 20 rotates. The remaining portion of the flexible screen 10 may then be wound around the outer sidewall of the roll 20 as the drive mechanism 30 drives the roll 20 to rotate.

It should be noted that the terms "first", "second" and "third" in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Specifically, the second suction member 211 is disposed corresponding to the first suction member 111, that is, the extending direction of the second suction member 211 is substantially parallel to the center line L. The second adsorption member 211 may have a strip shape. Further, the second absorption member 211 may be formed by arranging a plurality of strip absorption members at intervals, and the arrangement direction of the strip absorption members is substantially perpendicular to the central line L. Set up a plurality of interval distribution's second absorption piece 211, can form comparatively stable fixed connection structure with first absorption piece 111, avoid the flexible screen of first display part 11 position to appear dying the phenomenon and damage the flexible screen when drawing in.

In the embodiment of the present application, the winding drum 20 has an opening 212, and the opening 212 communicates with the accommodating cavity 23. In other words, the side wall 21 is provided with an opening 212 to communicate with the accommodating cavity 23, and the opening 212 enables the end portion of the side wall 21 to be disconnected, so that the flexible screen 10 can be partially accommodated in the accommodating cavity 23 when folded.

Specifically, when the flexible screen 10 is completely unfolded, the opening 212 faces the first suction member 111, so that the first display portion 11 of the flexible screen 10 is accommodated in the roll 20 when the first suction member 111 is suction-connected to the second suction member 211. Further, the second suction member 211 is disposed away from the opening 212 and faces the first suction member 111, i.e., the second suction member 211 is disposed on the inner sidewall of the winding drum 20 at the farthest position from the first suction member 111. When the second suction member 211 faces the first suction member 111, the second suction member 211 can provide a uniform suction force to the first display portion 11, so that the first display portion 11 can be smoothly accommodated in the accommodating cavity 23 of the winding drum 20.

Further, the first suction member 111 may be made of a ferromagnetic material, such as a substance having ferromagnetism (e.g., metal such as iron, nickel, cobalt, etc.), a metal alloy magnet (e.g., neodymium iron boron magnet, samarium cobalt magnet, alnico magnet, iron chromium cobalt magnet, etc.), a ferrite permanent magnet material, and the like. The second adsorption member 211 may employ an electromagnet to adsorb the first adsorption member 111 when being energized. It will be appreciated that the electromagnet, when energized, produces magnetism to magnetically attract the first attraction 111.

In the embodiment of the present application, the first absorbing member 111 may be an electromagnet, the second absorbing member 211 may be made of a ferromagnetic material, or both the first absorbing member 111 and the second absorbing member 211 may be electromagnets. Because the second adsorption part 211 is fixedly arranged on the inner side wall of the winding drum 20, when magnetic adsorption is performed, the first adsorption part 111 moves towards the second adsorption part 211 and forms a magnetic adsorption connection structure.

Of course, in other embodiments, the second suction member may be disposed on an outer sidewall of the winding drum 20, that is, the second suction member 211 is disposed on an outer sidewall of the winding drum 20. In other words, the side of the side wall 21 away from the accommodating cavity 23 is provided with the second adsorption member 211, and the second adsorption member 211 is connected with the first adsorption member 111 in an adsorption manner. It can be understood that the second suction member 211 is used for sucking the first suction member 111, that is, the second suction member 211 and the first suction member 111 form a suction connection relationship to fix the first display portion 11 of the flexible screen 10 to the outer side wall of the winding drum 20 when the winding drum 20 rotates. The remaining portion of the flexible screen 10 may then be wound around the outer sidewall of the roll 20 as the drive mechanism 30 drives the roll 20 to rotate.

Further, in the embodiment of the present application, both the first suction member 111 and the second suction member 211 may be made of a ferromagnetic material, so that the first suction member 111 and the second suction member 211 always maintain a suction connection relationship.

The embodiment of the application provides a flexible display device, it rotates to drive the reel through actuating mechanism, and the second adsorbs the piece and constitutes with first absorption spare and adsorb the relation of connection when the reel rotates, fix the first display part of flexible screen, thereby twine the lateral wall of reel with flexible screen when the reel rotates, reduce the space that the flexible screen took when drawing in and can realize the large-size screen display effect when the flexible screen expandes. In addition, through setting up the first display part that is located flexible screen middle part region to and first absorption spare and second absorb the piece and constitute and adsorb the connection, can realize that the flexible screen is two-way to be drawn in and two-way expansion, reach the purpose of practicing thrift the time that the flexible screen draws in or expand, and then promote the user and use experience.

Further, please refer to fig. 8 and 9 in combination, where fig. 8 is a partial structural diagram of another viewing angle when the flexible screen 10 of the electronic device 1000 in some embodiments of the present application is folded, and fig. 9 is a partial structural diagram of another viewing angle when the flexible screen 10 of the electronic device 1000 in some embodiments of the present application is unfolded. As described above, when the flexible screen 10 is unfolded, the flexible screen 10 includes the first display part 11, the second display part 12, and the third display part 13 located on the same plane to provide a large screen display effect. When the flexible screen 10 is folded, the first display part 11 is accommodated in the accommodating cavity 23 of the winding drum 20, the second display part 12 is wound on the outer side wall of the winding drum 20, and the third display part 13 is partially wound on the outer side wall of the winding drum 20, and the other part is used for normal display, namely, a small screen display effect is provided.

In the embodiment of the present application, the third display portion 13 may generally include a furled display portion 131 and a furled winding portion 132. The furled winding portion 132 is disposed adjacent to the second display portion 12, and the furled display portion 131 is disposed away from the second display portion 12. In other words, the furling winding portions 132 are symmetrically disposed along the central line L and distributed on two sides of the second display portion 12; the furled display parts 131 are symmetrically disposed along the central line L and are distributed on two sides of the furled winding part 132 away from the second display part 12.

Further, when the flexible screen 10 is folded, the folded display part 131 of the third display part 13 is located at the position of the second display part 12 to replace the second display part 12 for displaying, and the flexible screen 10 is folded on the winding drum 20 except for the folded display part 131. Specifically, the area of the folded display portion 131 is substantially the same as the area of the second display portion 12, so as to avoid affecting the display effect of the flexible screen 10 when folded. In order to realize the display effect of the ultra-large screen when the flexible screen 10 is unfolded, the influence factor is mainly the furled winding part 132 of the third display part 13.

For example, when the area of the furled wrapping part 132 is the same as the area of the furled display part 131, that is, the area of the second display part 12 is 1/2 of the area of the third display part, the display area of the flexible screen 10 when being unfolded is about 3 times the display area of the flexible screen 10 when being furled.

When the area of the furled winding part 132 is smaller than the area of the furled display part 131, that is, the area of the second display part 12 is larger than 1/2 of the area of the third display part, the display area of the flexible screen 10 when being unfolded is approximately 3 times smaller than the display area of the flexible screen 10 when being furled. Taking the area of the furled winding part 132 as half of the area of the furled display part 131 as an example, the area of the second display part 12 is about 2/3 of the area of the third display part 13, and at this time, the display area of the flexible screen 10 when being unfolded is about 2.5 times of the display area of the flexible screen when being furled.

When the area of the furled winding portion 132 is larger than the area of the furled display portion 131, that is, the area of the second display portion 12 is smaller than 1/2 of the area of the third display portion, the display area of the flexible screen 10 when being unfolded is approximately 3 times larger than the display area of the flexible screen 10 when being furled. Taking the area of the furled wrapping portion 132 twice the area of the furled display portion 131 as an example, the area of the second display portion 12 is about 1/3 of the area of the third display portion 13, and at this time, the display area of the flexible screen 10 when being unfolded is about 4 times the display area of the flexible screen 10 when being furled.

Based on this, in the embodiment of the present application, in order to make the display area of the flexible screen 10 not less than 3 times as large as the display area of the flexible screen 10 when the flexible screen 10 is folded, so as to achieve the super-large screen display effect, the area of the second display screen 12 is generally not more than 1/2 of the area of the third display portion 13. It can be understood that, when the area of the flexible screen 10 when being unfolded is about 3 times of the display area of the flexible screen 10 when being folded, the occupied space of the electronic device 1000 when being carried by the electronic device can be greatly reduced when the flexible screen 10 is folded, thereby providing great portability and improving the user experience.

In some embodiments of the present application, please refer to fig. 10, fig. 10 is a partial structural schematic diagram of a flexible display device 100 in some embodiments of the present application, and the flexible display device 100 may further include a supporting assembly 40. The support assembly 40 is disposed on the non-display surface of the flexible screen 10 to support the flexible screen 10.

Specifically, the end of the support member 40 parallel to the telescopic direction of the flexible screen 10 is fixedly connected to the housing 200. Wherein, when the flexible screen 10 is completely unfolded, the supporting component 40 is supported on the second display part 12; when the flexible screen 10 is wound on the winding drum 20, that is, when the flexible screen 10 is folded, the support member 40 is supported on a portion of the third display portion 13. In combination with the above, when the flexible screen 10 is folded, the supporting assembly 40 is supported by the folded display portion 131 of the third display portion 13.

Further, the support assembly 40 includes a first support 41 and a second support 42, and the first support 41 and the second support 42 are symmetrically disposed along the first display portion 11 of the flexible screen 10, that is, the first support 41 and the second support 42 are symmetrically disposed along the center line L. The end portions of the first and second supporting

members

41 and 42 adjacent to each other have a first gap 43, and the first gap 43 serves as an inlet and an outlet of the flexible screen 10 when the flexible screen 10 is extended and contracted.

When the flexible screen 10 is completely unfolded, the first gap 43 is disposed opposite to the opening 212 of the winding drum 20 to provide an avoidance space for the first display part 11 of the flexible screen 10 to sink, i.e., the first gap 43 is disposed corresponding to the first display part 11 and avoids the first suction attachment 111. In the present embodiment, the width of the first gap 43 is approximately 1-3cm, for example, the width of the first gap 43 may be 1cm, 2cm, 3cm, etc. It can be understood that the first gap 43 not only provides an access way for the flexible screen 10 to stretch, but also avoids the first suction attachment 111 of the first display part 11 when the flexible screen 10 is fully unfolded for displaying, so that the surface of the flexible screen 10 is relatively flat.

In some embodiments of the present application, please refer to fig. 11 and 12, fig. 11 is a partial structural schematic view of a flexible display device 100 in some embodiments of the present application, and fig. 12 is a sectional structural schematic view taken along the direction B-B in fig. 11, where the flexible display device 100 may further include a position-limiting assembly 50, and the position-limiting assembly 50 is disposed on a side of the support assembly 40 close to the winding drum 20. Further, the limiting assembly 50 avoids the first suction fitting 111 during the movement of the flexible screen 10, and the limiting assembly 50 is used for supporting the portion of the flexible screen 10 corresponding to the first gap 43.

Specifically, the limiting assembly 50 may include a first limiting member 51 and a second limiting member 52, where the first limiting member 51 and the second limiting member 52 are symmetrically disposed along the first display portion 11 of the flexible screen 10, that is, the first limiting member 51 and the second limiting member 52 are symmetrically disposed along the central line L. The end portions of the first stopper 51 and the second stopper 52 close to each other have second gaps (53, 54) corresponding to the first gap 43. The second gaps (53, 54) communicate with the first gap 43 to serve as an inlet and outlet of the flexible panel 10 when the flexible panel 10 is expanded and contracted, that is, the flexible panel 10 passes through the first gap 43 and the second gaps (53, 54) in order when the flexible panel 10 is expanded and contracted. Further, when the flexible screen 10 performs the telescopic motion, the first limiting member 51 and the second limiting member 52 are away from each other to avoid the first suction attachment 111 and the flexible screen 10, so as to avoid the flexible screen 10 in the contact motion from affecting the telescopic stability of the flexible screen 10. When the flexible screen 10 is in a still display state, the first limiting member 51 and the second limiting member 52 are close to each other for supporting a portion of the flexible screen 10, so as to avoid that the display effect is significantly affected by too much sinking of the flexible screen 10 at the first gap 43.

Based on this, when the first stopper 51 and the second stopper 52 are close to each other to support the flexible screen 10, the width of the second gap 53 when the flexible screen 10 is at rest is 0.5 to 5 mm. In the present embodiment, the width of the second gap 53 when the flexible screen 10 is at rest may be 0.5mm, 1.0mm, 1.5mm, 2.0mm, etc. The width of the second gap 54 during movement of the flexible screen is not less than the width of the first gap 43 when the first and second retaining

members

51 and 52 are moved away from each other to avoid the flexible screen 10 and the first suction fitting 111.

Further, the limiting assembly 50 is further provided with a power member 55, and the power member 55 is used for driving the first limiting member 51 and the second limiting member 52 to move away from or close to each other. It is understood that the power member 55 may be a motor driving mechanism, a cylinder driving mechanism, a magnetic driving mechanism, etc. which can drive the first limiting member 51 and the second limiting member 52 to move. For example, taking the power member 55 as a motor driving mechanism as an example, the motor rotates forward or backward to drive the first limiting member 51 and the second limiting member 52 to approach or separate from each other.

Specifically, during the telescopic movement of the flexible screen 10, the power member 55 drives the first limiting member 51 and the second limiting member 52 to move away from each other along the X direction shown in fig. 12, and when the power member 55 stops driving, the first limiting member 51 and the second limiting member 52 form a second gap 54 to avoid the flexible screen 10. When the flexible screen 10 is in a static state after moving, the power member 55 drives the first limiting member 51 and the second limiting member 52 to approach each other along the X direction shown in fig. 12, and when the power member 55 stops driving, the first limiting member 51 and the second limiting member 52 form a second gap 53 to support the flexible screen 10.

It can be understood that when the flexible screen is folded, the flexible screen located at the first gap is roughly in a herringbone shape, and at the moment, splicing optimization can be performed according to the display requirements of the flexible screen, so that the flexible screen has a complete display effect.

In some embodiments of the present application, please refer to fig. 11 to fig. 13 in combination, fig. 13 is a partial structural schematic diagram of a flexible display device 100 in some embodiments of the present application, and the flexible display device 100 may further include a telescopic assembly 60, and the telescopic assembly 60 may be telescopic along a moving direction of the flexible screen 10. The telescopic assembly 60 supports the third display part 13 of the flexible screen 10 when the flexible screen 10 is completely unfolded, and the telescopic assembly 60 is retracted to a side of the flexible screen 10 close to the winding drum 20 when the flexible screen 10 is wound on the winding drum 20, that is, when the flexible screen 10 is folded.

Specifically, the support member 50 is disposed between the flexible screen 10 and the telescopic member 60 in a display direction parallel to the flexible screen 10. In other words, when the flexible screen 10 is fully unfolded, the telescopic assembly 60 extends from the side of the support assembly 50 remote from the flexible screen 10; when flexible screen 10 is collapsed, telescoping assembly 60 is retracted to the side of support assembly 50 away from flexible screen 10. As shown in fig. 11, when the flexible screen 10 is folded, the telescopic assembly 60 is folded at a side of the support assembly 50 close to the winding drum 20 and is arranged to be set to be away from the end of the winding drum 20. As shown in fig. 13, when the flexible screen 10 is unfolded, the telescopic assembly 60 is extended out of the housing and extended in the unfolding direction of the flexible screen 10, so that the telescopic assembly 60 can fully support the third display part 13 of the flexible screen 10.

Further, referring to fig. 14, fig. 14 is an enlarged partial structure view of a region C in fig. 13, and the telescopic assembly 60 may generally include a frame 61, a sliding member 62 and a sliding slot 63. The sliding member 62 is disposed at an end of the frame 61 and is slidably connected to the sliding groove 63. The sliding member 62 cooperates with the sliding groove to drive the frame 61 to extend and retract, so that the frame 61 can support the third display portion 13 of the flexible screen 10 when the flexible screen 10 is completely unfolded. It can be understood that the telescopic assemblies 60 are distributed on both sides of the winding drum 20 or the housing 200, that is, the telescopic assemblies 60 may be two sets of telescopic assemblies, so as to provide a bidirectional telescopic structure when the flexible screen 10 is telescopic, thereby improving the unfolding or folding efficiency of the flexible screen 10. Wherein, the two groups of telescopic components have the same structure, so that the telescopic components are not distinguished.

In order to allow the frame 61 to escape the drum 20 when retracted, the frame 61 is of a generally letter-shaped configuration. That is, the frame 61 is generally surrounded by three sides to form a frame structure with one side open, and the opening direction of the frame structure faces the winding drum 20, so that the frame 61 can be retracted from the winding drum 20 and the limiting assembly 50, and the frame 61 can be completely accommodated in the housing 200. It can be appreciated that when the telescoping assembly 60 contracts, the two sets of telescoping assemblies can also be arranged to avoid each other to reduce the space inside the housing that the telescoping assembly 60 occupies when contracting.

Further, the frame 61 may include a first side frame 611, a second side frame 612, and a connection frame 613 connecting the first side frame 611 and the second side frame 612, which are oppositely disposed. When the frame 61 is accommodated in the housing 200, the first side frame 611 and the second side frame 612 are respectively disposed at an interval with two end portions of the winding drum 20, that is, the winding drum 20 is substantially sandwiched between the first side frame 611 and the second side frame 612, and at this time, the connection frame 613 corresponds to an outer peripheral edge of the housing 200 to support an edge of the flexible screen 10. When the frame 61 is extended out of the housing 200, that is, supported on the third display portion 13 of the flexible screen 10, the connection frame 63 is supported on an end portion of the flexible screen 10 away from the center line L or away from the roll 20.

Further, the sliding member 62 is disposed at an end of the frame 61 close to the winding drum, that is, an end of the first side frame 611 and the second side frame 612 far from the connection frame 613. It is understood that 1 or 2 sliding members 62 may be provided, and when 1 sliding member 62 is provided, it is provided at an end of the first side frame 611 or the second side frame 612 far from the connecting frame 613; when there are 2 sliding frames 62, they are respectively disposed at the ends of the first side frame 611 and the second side frame 612 far from the connecting frame 613. The sliding member 62 is disposed on one side of the frame 61 close to the housing 200, and the sliding groove 63 is disposed on an inner side wall of the housing 200, so that when the sliding member 62 and the sliding groove 63 slide in a matching manner, the frame 61 can be stably supported to stretch.

In some embodiments of the present application, the telescopic assembly 60 may further include a gear 64 and a rack 65, the gear 64 is disposed near the sliding member 62, the gear 64 is disposed on a side of the frame 61 facing away from the flexible screen 10 and extends along a moving direction of the flexible screen 10, wherein the gear 64 and the rack 65 cooperate to move the frame 61.

Specifically, the gear 64 is fixedly connected with the housing 200 and can rotate along a gear shaft, the gear 64 is arranged inside the outer periphery of the housing 200, and when the flexible screen 10 is completely unfolded, the gear 64 is positioned at the end of the first side frame 611 and/or the second side frame 612 far away from the connecting frame 613; when the flexible screen 10 is completely folded, the gear 64 is located at the end of the first side frame 611 and/or the second side frame 612 near the connecting frame 613. The rack 65 is arranged on the side of the first side frame 611 and/or the second side frame 612 facing away from the flexible screen 10, and is in meshed connection with the gear 64. The sliding phenomenon of the frame 61 when the electronic device is used can be avoided by the gear 64 and the rack 65 cooperating to drive the frame 61 to move.

Further, the end of the flexible screen 10 away from the winding drum 20 is fixedly connected with the end of the frame 61 away from the winding drum 20, that is, the end of the third display part 13 of the flexible screen 10 away from the first display part 11 is fixedly connected with the connection frame 613, so that the frame 61 can move synchronously with the third display part 13 of the flexible screen 10.

Specifically, referring to fig. 15 and 16 in combination, fig. 15 is a schematic view of a partial cross-sectional structure along the direction D-D in fig. 13, and fig. 16 is an enlarged schematic view of a portion of the structure in the region E in fig. 15. Due to the fact that the support assembly 40 is arranged at least at intervals between the frame 61 and the flexible screen 10, a distance exists between the frame 61 and the flexible screen 10. In other words, the end of the flexible screen 10 away from the roll 20 and the end of the frame 61 away from the roll 20 have the third gap 66 in the direction perpendicular to the flexible screen 10, that is, in the Z direction shown in fig. 15, the connection frame 613 of the frame 61 and the end of the third display part 13 of the flexible screen 10 away from the first display part 11 have the third gap 66. The width of the third gap 66 is approximately 0.2-0.5mm, subject to the thickness of the support member 40. It will be appreciated that the width of the third gap 66 may vary for support members 40 of different thicknesses, and that as the overall configuration of the electronic device varies, the width of the third gap 66 may vary accordingly. It should be appreciated that the width of third gap 66 should not be less than the thickness of support assembly 40.

Because there is the third gap 66 between the frame 61 and the flexible screen 10, which is not beneficial to maintaining the flatness of the flexible screen 10, in the embodiment of the present application, the filling member 67 is filled in the third gap 66, so that the flexible screen 10 has uniform flatness when being stretched and displayed. In other words, the filler 67 serves to fixedly connect the flexible screen 10 with the frame 61, and to support the flexible screen 10. The filling rib 67 is arranged between the connection frame 613 of the frame 61 and the flexible screen 10, so that the connection and fixation function is achieved on one hand, and the buffer function can also be achieved on the other hand. It will be appreciated that the thickness of the filler 67 substantially corresponds to the width of the third gap 66 to ensure flatness of the flexible member 10.

In some embodiments of the present application, the filling member 67 may be made of colloid or foam, and may play a role of buffering while fixedly connecting the flexible screen 10 and the frame 61. Of course, in other embodiments, the filling member 67 may be made of a material with certain elasticity, such as foam, rubber, etc.; or may be made of one or more colloids such as double-sided adhesive, OCA optical adhesive (OCA), Optically Clear Resin (OCR), Pressure Sensitive Adhesive (PSA).

Of course, in other embodiments, the frame and the flexible screen may be fixedly connected by means of a snap, that is, a snap device corresponding to an end of the flexible screen 10 is provided on the connection frame 613 of the frame 61 to cooperate with the connection frame 613 to fix the flexible screen 10. It will be appreciated that the ends of the flexible screen 10 may be secured to the connection frame 613 by snap-fit means such as a snap-fit, a nut snap, a snap, etc.

At the same time, the roll 20 is opened toward the first display unit 11, the first suction member 111 and the second suction member 211 are in an off state, and the gear of the drive mechanism 30 is in a stationary state. At this time, the flexible screen 10 may present a large screen display effect, for example, a better use experience for watching videos, game entertainment, and the like.

When the electronic device does not need to be used or carried, that is, the flexible screen 10 needs to be folded, a certain external force can be applied to the telescopic assembly 60 to enable the frame 61 to move to a certain displacement in the direction of the winding drum 20, at this time, the movement of the frame 61 can be sensed through the position sensor, the first absorbing part or the second absorbing part is powered on to generate magnetic attraction, so that the first absorbing part and the second absorbing part form an absorbing connection relationship to fix the first absorbing part on the winding drum 20. Meanwhile, the driving mechanism 30 is further triggered to move to drive the gear of the driving mechanism 30 to rotate, so as to drive the winding drum 20 to rotate, and the flexible screen 10 is furled when the winding drum 20 rotates, so that the flexible screen 10 can be wound on the outer side wall of the winding drum 20. During the folding process of the flexible screen 10, the first limiting member 51 and the second limiting member 52 move away from each other under the action of the power member 55 to avoid the first suction attachment 111 and the flexible screen 10. When the flexible screen 10 is completely folded, the first retaining member 51 and the second retaining member 52 approach each other under the action of the power member 55 to support a portion of the flexible screen 10. In this case, the display area of the flexible screen 10 is approximately 1/3 of the display area, which is convenient for carrying.

It is understood that when the flexible screen 10 is completely folded, the first display portion 11 of the flexible screen 10 is substantially located inside the winding drum 20, and the second display portion 12 and a part of the third display portion 13 are wound around the outer side wall of the winding drum 20.

At the same time, the driving mechanism 30 is further triggered to move to drive the gears of the driving mechanism 30 to rotate, so as to drive the winding drum 20 to rotate, and the flexible screen 10 is gradually released when the winding drum 20 rotates. During the releasing process of the flexible screen 10, the first limiting member 51 and the second limiting member 52 move away from each other under the action of the power member 55 to avoid the first suction device 111 and the flexible screen 10. When the flexible screen 10 is completely folded, the first retaining member 51 and the second retaining member 52 approach each other under the action of the power member 55 to support a portion of the flexible screen 10. At this time, under the external force, the frame 61 is gradually and completely unfolded to support the flexible screen 10, so that the flexible screen 10 exhibits an ultra-large area display effect.

It will be appreciated that the movement of the frame 61 of the telescopic assembly 60 is effected by an external force, although a drive (e.g. a motor) may be provided to drive the gear 64 to rotate and thus the frame 61 to move.
