DETAILED DESCRIPTION



[0020] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with aspects related to the disclosure as recited in the appended claims.

[0021] A flexible display screen can be a foldable screen. When a user wants to use a larger display screen, the user can expand the screen manually; and when the user wants to use the normal display screen, the user can fold the expanded screen back manually.

[0022] However, user's manual operations are required in the expansion and folding of the display screen, resulting in poor user experience.

[0023] In contrast, various embodiments of the present disclosure can have one or more of the following advantages.

[0024] For example, the driving assemblies are controlled to drive the telescopic components to push or pull the side housings by arranging the driving assemblies and the telescopic components inside the mobile terminal, such that the flexible display screen expands or contracts about the corresponding reel, thereby enabling automatic expansion or contraction of the flexible display screen, without manual operations by a user, thereby leading to improved user experience.

[0025] FIG. 1 and FIG. 2 exemplarily show a schematic structural diagram of a mobile terminal respectively. In FIG. 1, a display screen of the mobile terminal is in a contracted state. In FIG. 2, the display screen of the mobile terminal is in an expanded state. The mobile terminal 100 includes a display screen 110, a support frame 120, a first side housing 130, a first reel 140 and a first driving assembly 150.

[0026] The display screen 110 is arranged on the support frame 120, and a first side portion of the display screen 110 is made of a flexible material.

[0027] The display screen 110 is used to display images and colors. Optionally, the display screen 110 is a touch display screen. In addition to a display function, the touch display screen has a function of receiving a touch operation (such as clicking, sliding, pressing, etc.) of a user. Optionally, the display screen 110 can be an OLED (Organic Light-Emitting Diode) screen.

[0028] Exemplarily, the display screen 110 includes a first side portion and other portions. The first side portion can be made of a flexible material, and the other portions can be made of a flexible material or a rigid material. When the other portions are made of a flexible material, the display screen 110 functions as a complete flexible display screen. The flexible display screen refers to a display screen that can be bent and is flexible. The flexible display screen can change a screen form by bending, folding, and the like.

[0029] The support frame 120 is a main frame of the mobile terminal 100 and can also be referred to as a body. The support frame 120 is generally in a shape of a hexahedron, and a part of edges or corners of the hexahedron can be formed with a curved chamfer. The front surface of the support frame 120 is generally in a shape of a rounded rectangle or a rectangular rectangle. In this embodiment of the present disclosure, the support frame 120 can be used to support the display screen 110. A main chip and other main components can be accommodated inside the support frame 120 as well.

[0030] The first reel 140 is arranged in a cavity in the first side housing 130, and the first side portion of the display screen 110 circumferentially surrounds about the first reel 140.

[0031] An outer contour of the first side housing 130 can be U-shaped. A cavity is formed inside the first side housing 130 to accommodate the first reel 140. An opening is further formed in a position of the first side housing where the cavity is formed. The first side portion of the display screen 110 circumferentially surrounds about the first reel 140 via the opening.

[0032] Optionally, the end of the first side portion of the display screen 110 is fixed to the first reel 140. For example, the end of the first side portion of the display screen 110 can be fixed to the first reel 140 by gluing, or in a manner of plate-to-plate flattening. The manner of fixing the end of the first side portion of the display screen 110 to the first reel 140 will not be limited in embodiments of the present disclosure.

[0033] In order to prevent the surface of the display screen 110 from being damaged by the rubbing between the first side portion of the display screen 110 during the telescoping process and the sidewall of the cavity, a safety gap is reserved between the first side portion of the display screen 110 and the sidewall of the cavity to prevent the first side portion of the display screen 110 from rubbing with the sidewall of the cavity.

[0034] The first driving assembly 150 is connected to the first side housing 130 through a first telescopic component 160.

[0035] In an embodiment of the present disclosure, the first driving assembly 150 can convert electrical energy into mechanical energy, such that the first telescopic component 160 can push or pull the first side housing 130 to move. Optionally, the first driving assembly 150 is a motor.

[0036] The first telescopic component 160 refers to a telescopic component. Exemplarily, the first telescopic component 160 can be a connecting rod or other component having flexibility. The type of the first telescopic component will not be limited in embodiments of the present disclosure.

[0037] During the expansion process, the first driving component 150 drives the first telescopic component 160 to push the first side housing 130 outwards, and the first side portion of the display screen 110 expands about the first reel 140. The mobile terminal 100 changes from a state shown in FIG. 1 to a state shown in FIG. 2.

[0038] During the contraction process, the first driving component 150 drives the first telescopic component 160 to pull the first side housing 130 inwards, the first side portion of the display screen 110 contracts about the first reel 140. The mobile terminal 100 changes from a state shown in FIG. 2 to a state shown in FIG. 1.

[0039] By circumferentially surrounding the first side portion of the display screen 110 about the first reel 140, the first side portion of the display screen 110 has a self-contracting force. As such, the retraction of the first side portion can be aided by the self-contracting force.

[0040] During the expansion of the display screen 110, the first driving assembly 150 drives the first telescopic component 160 to push the first side housing 130 outwards, so that the first side housing 130 moves away from the support frame 120. When the first side housing 130 moves, the first reel 140 will be driven to rotate. In this case, the first side portion of the display screen 110 overcomes the self-contracting force to affect the expansion of the first side portion of the display screen 110. When the first side portion of the display screen 110 is in an expanded state, a display area of the mobile terminal 100 increases. According to the technical solution provided by this embodiment of the present disclosure, the screen display area of the mobile terminal 100 increases in the case where the mobile terminal 100 is convenient to carry.

[0041] During the contraction process of the display screen 110, the first driving assembly 150 drives the first telescopic component 160 to pull the first side housing 130 inwards, so that the first side housing 130 moves close to the support frame 120. When the first side housing 130 moves, the first reel 140 will be driven to rotate. In this case, the first side portion of the display screen 110 contracts by means of the self-contracting force.

[0042] Optionally, as shown in FIG. 3 and FIG. 4, a first comb plate 121 is arranged on a side, connected to the first side housing 130, of the support frame 120. A second comb plate 131 which is adaptive to the first comb plate 121 is arranged on a side, connected to the support frame 120, of the first side housing 130. The first comb plate 121 and the second comb plate 131 are both attached to the back surface of the display screen 110.

[0043] The first comb plate 121 and the second comb plate 131 refer to a device having a comb tooth structure respectively. The first comb plate 121 and the second comb plate 131 each include a plurality of teeth. Optionally, the first comb plate 121 is the same as the second comb plate 131 in terms of any or all of the number of the teeth, the width of each tooth and the depth of each tooth groove.

[0044] When the first side portion of the display screen 110 is in the contracted state, a schematic diagram showing a state of the first comb plate 121 and the second comb plate 131 is as shown in FIG. 3. In this case, the teeth of the first comb plate 121 are completely meshed with the teeth of the second comb plate 131, and no tooth is exposed. When the first side portion of the display screen 110 is in the expanded state, a schematic diagram showing a state of the first comb plate 121 and the second comb plate 131 is as shown in FIG. 4. In this case, the teeth of the first comb plate 121 and the teeth of the second comb plate 131 are exposed. The first comb plate 121 and the second comb plate 131 can play a good supporting role for the display screen 110, thereby avoiding a phenomenon of an unlevel screen caused by disengagement of the support frame 120 from the first side housing 130.

[0045] Optionally, as shown in FIG. 1 and FIG. 2, a recess portion 132 is formed at the bottom of the first side housing 130. A boss portion 122 which is adaptive to the recess portion 132 is formed at the bottom of a side, connected to the first side housing 130, of the support frame 120.

[0046] In an exemplary embodiment, a camera is arranged at the recess portion 132. In the case of photographing, the first side housing 130 is pushed outwards, and the camera is exposed from the mobile terminal 100 to meet the user's photographing needs. By arranging the camera at the recess portion 132 at the bottom of the first side housing 130, the camera is not exposed at ordinary times and can thus be protected.

[0047] Optionally, the mobile terminal 100 further includes a limiting mechanism. The limiting mechanism is configured to limit a maximum displacement of the first side housing 130 during the expansion of the first side portion of the display screen 110 about the first reel 140. By means of the above manner, the screen is prevented from being stretched too much to cause damage caused by the excessive displacement of the first side housing 130.

[0048] The limiting mechanism can be a positioning pin, a positioning screw, a Hall assembly, etc., which will not be limited in this embodiment of the present disclosure.

[0049] In some exemplary embodiments, when the limiting mechanism is a positioning pin, a positioning screw or the like, the limiting mechanism can be arranged on the boss portion 122 of the support frame 120. Because the limiting mechanism functions to limit the first side housing 130, when the first side housing 130 moves to a position where the limiting mechanism is located, the first side housing 130 cannot continue to move away from the support frame 120. Further, the first side portion of the display screen 110 will stop expanding.

[0050] In other exemplary embodiments, the limiting mechanism can include magnetic elements and a Hall sensor. The magnetic elements can include a permanent magnet element and a soft magnetic element. The Hall sensor is a magnetic field sensor fabricated according to the Hall effect. In an embodiment of the present disclosure, the Hall sensor can indirectly measure a displacement between the respective magnetic element and the Hall sensor, that is, a displacement between the support frame 120 and the first side housing 130. Optionally, the magnetic elements are arranged on the support frame 120, and the Hall sensor is arranged on the first side housing 130; or the magnetic elements are arranged on the first side housing 130, and the Hall sensor is arranged on the support frame 120. When the displacement between the support frame 120 and the first side frame housing 130 is greater than a preset threshold, the mobile terminal controls the first driving assembly150 to stop working, thereby causing the first side housing 130 to stop moving, and further causing the first side portion of the display screen 110 to stop expanding.

[0051] By arranging the limiting mechanism in the mobile terminal 100, the display screen 110 can be well protected from the damage caused by the excessive expansion of the display screen 110.

[0052] Of course, by setting the telescopic length of the first telescopic component 160, the limiting function of the limiting mechanism can also be achieved.

[0053] In summary, in the technical solution provided by this embodiment of the present disclosure, the driving assemblies are controlled to drive the telescopic components to push or pull the side housings by arranging the driving assemblies and the telescopic components inside the mobile terminal, such that the flexible display screen expands or contracts about the corresponding reel, thereby enabling automatic expansion or contraction of the flexible display screen, without manual operations by a user, and the convenience is high.

[0054] In addition, a comb tooth structure is arranged on a side, connected to the corresponding side housing, of the support frame to support the flexible display screen better, thereby protecting the flexible display screen.

[0055] Moreover, by arranging the camera at the recess portion at the bottom of the first side housing, the camera is not exposed at ordinary times and can thus be protected.

[0056] In some embodiments, the camera is hidden when the first side portion is retracted, and becomes exposed and ready for image capturing when the first side portion is in the expanded state.

[0057] FIG. 5 is a schematic structural diagram of a mobile terminal shown according to another exemplary embodiment. The mobile terminal 100 includes a display screen 110, a support frame 120, a first side housing 130, a first reel 140, a first driving assembly 150, a second side housing 170, a second reel 180, and a second driving assembly 190.

[0058] An introduction to the display screen 110, the support frame 120, the first side housing 130, the first reel 140, and the first driving assembly 150 can refer to the above embodiments, and will not be described herein again.

[0059] A second side portion of the display screen 110 opposite the first side portion is made of a flexible material, i.e., the second side portion of the display screen 110 is a flexible display screen.

[0060] Exemplarily, the display screen 110 includes a first side portion, a second side portion, and an intermediate portion. The first side portion and the second side portion are made of a flexible material. The intermediate portion can be made of a flexible material or a rigid material. When the intermediate portion is made of a flexible material, the display screen 110 is a complete flexible display screen.

[0061] The second reel 180 is arranged in a cavity inside the second side housing 170, and the second side portion of the display screen 110 circumferentially surrounds about the second reel 180.

[0062] An outer contour of the second side housing 170 can be U-shaped. A cavity is formed inside the second side housing 170 to accommodate the second reel 180. An opening is further formed in a position of the second side housing 170 where the cavity is formed. The second side portion of the display screen 110 circumferentially surrounds about the second reel 180 via the opening.

[0063] Optionally, the end of the second side portion of the display screen 110 is fixed to the second reel 180. For example, the end of the second side portion of the display screen 110 can be fixed to the second reel 180 by gluing, or in a manner of plate-to-plate flattening. The manner of fixing the end of the second side portion of the display screen 110 to the second reel 180 will not be limited in this embodiment of the present disclosure.

[0064] In order to prevent the surface of the display screen 110 from being damaged by the rubbing between the second side portion of the display screen 110 during the telescoping process and the sidewall of the cavity, a safety gap is reserved between the second side portion of the display screen 110 and the sidewall of the cavity to prevent the second side portion of the display screen 110 from rubbing with the sidewall of the cavity.

[0065] The second driving assembly 190 is connected to the second side housing 170 through a second telescopic component 200.

[0066] In an embodiment of the present disclosure, the second driving assembly 190 can convert electrical energy into mechanical energy, such that the second telescopic component 200 can push or pull the second side housing 170 to move. Optionally, the second driving assembly 190 is a motor.

[0067] The second telescopic component 200 refers to a telescopic component. Exemplarily, the second telescopic component 200 can be a connecting rod or other component having flexibility. The type of the second telescopic component 200 will not be limited in this embodiment of the present disclosure.

[0068] During the expansion process, the second driving assembly 190 drives the second telescopic component 200 to push the second side housing 170 outwards, and the second side portion of the display screen 110 expands about the second reel 180.

[0069] During the contraction process, the second driving assembly 190 drives the second telescopic component 200 to pull the second side housing 170 inwards, and the second side portion of the display screen 110 contracts about the second reel 180.

[0070] An introduction to the expansion process and the contraction process of the second side portion of the display screen 110 can refer to an introduction to the expansion process and the contraction process of the first side portion of the display screen 110, and will not be described herein.

[0071] Optionally, a third comb plate is arranged on a side, connected to the second side housing 170, of the support frame 120. A fourth comb plate which is adaptive to the third comb plate is arranged on a side, connected to the support frame 120, of the second side housing 170. The third comb plate and the fourth comb plate are both attached to the back surface of the display screen 110.

[0072] An introduction to the third comb plate and the fourth comb plate can refer to the introduction to the first comb plate and the second comb plate, and will not be described herein again.

[0073] The first side portion and the second side portion of the display screen 110 can be simultaneously expanded, and a display area is maximum at this time. Of course, the first side portion of the display screen 110 can be expanded, and the second side portion can be contracted; or the first side portion of the display screen 110 can be contracted, and the second side portion can be expanded. The expansion or contraction of the display screen 110 is determined by user's display requirements. When the user wants the largest display area, the first side portion and the second side can be simultaneously expanded. In the technical solutions provided by this embodiment of the present disclosure, the display forms are diversified.

[0074] In summary, in the technical solution provided by this embodiment of the present disclosure, by arranging the driving assemblies on both sides and the telescopic components, the display area increases, and the display forms are diversified, such that the user's display requirements can be satisfied better.

[0075] FIG. 6 is a flowchart of a screen control method shown according to an exemplary embodiment, which is applied to the mobile terminal as described above. An executive body of the method can be the mobile terminal as described above. The method includes the following steps (steps 601-602).

[0076] In step 601, a screen expansion instruction is received.

[0077] The screen expansion instruction is an operation instruction for expanding the display screen. The screen expansion instruction can be triggered by a system interaction button in the display screen, or by a physical or touch key provided on the mobile terminal. Of course, in other possible implementations, the screen expansion instruction can also be triggered by user's voice and gesture. The triggering manner of the screen expansion instruction will not be limited in this embodiment of the present disclosure.

[0078] In step 602, the first driving assembly is controlled according to the screen expansion instruction to drive the first telescopic component to push the first side housing outwards, so that the first side portion of the display screen expands about the first reel.

[0079] The first driving assembly drives the first telescopic component to push the first side housing outwards, such that the first side housing moves away from the support frame. When the first side housing moves, the first reel is driven to rotate. In this case, the first side portion of the display screen overcomes the self-contracting force to effect the expansion of the first side portion of the display screen.

[0080] Exemplarily, when a user wants to view a video using a larger display area, he/she can click on a system button on the display screen to trigger a screen expansion instruction. After the mobile terminal receives the screen expansion instruction, the first side portion of the display screen is expanded, and the mobile terminal provides a larger display area for the user to view the video.

[0081] Optionally, as shown in FIG. 7, the method further includes the following steps (steps 603-604).

[0082] In step 603., a screen contraction instruction is received.

[0083] The screen contraction instruction is an operation instruction for contracting the display screen. The screen contraction instruction can be triggered by a system interaction button in the display screen, or by a physical or touch key provided on the mobile terminal. Of course, in other possible implementations, the screen contraction instruction can also be triggered by user's voice and gesture. The triggering manner of the screen contraction instruction will not be limited in this embodiment of the present disclosure.

[0084] In step 604, the first driving assembly is controlled according to the screen contraction instruction to drive the first telescopic component to pull the first side housing inwards, so that the first side portion of the display screen contracts about the first reel.

[0085] The first driving assembly drives the first telescopic component to pull the first side housing inwards, such that the first side housing moves close to the support frame. When the first side housing moves, the first reel is driven to rotate. In this case, the first side portion of the display screen contracts by means of the self-contracting force.

[0086] Exemplarily, after the user finishes viewing the video, the user does not need a larger display area, and he/she will click a system button on the display screen again to trigger the screen contraction instruction. After the mobile terminal receives the screen contraction instruction, the first side portion of the display screen contracts, and the display area of the mobile terminal returns to normal.
