Description

electronic devices Technical Field

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

[0002] With the continuous development of display technology, foldable terminals (such as foldable phones) are becoming a trend in future mobile electronic products. When unfolded, foldable terminals can provide a larger display area, improving visual effects, while when folded, they are compact and easy to carry. As a result, they are becoming more and more popular among users.

[0003] However, the display screen of a foldable terminal moves relative to the frame during folding and unfolding. Typically, a fixed structure is installed around the display screen to secure it, which results in a black border around the display screen. With the current trend towards full-screen displays, reducing the width of the visible black border around the display screen of foldable terminals is an urgent issue.

[0004] Summary of the Invention

[0005] In order to solve the above technical problems, the present application provides an electronic device that can reduce the width of the visible black border of the display screen of the electronic device (such as a foldable terminal), which is conducive to realizing a full-screen design of the electronic device.

[0006] The present application provides an electronic device, which includes: a body; a display screen fixed to the body, the display screen including a display area and a non-display area; a screen decoration located on a side of the display screen facing away from the body, the screen decoration including: a decoration segment extending along a first direction; the decoration segment including a fixing portion and a shielding portion extending along the first direction and arranged along a second direction; the fixing portion is fixedly connected to the body, the shielding portion covers at least part of the non-display area of ​​the display screen and at least part of the gap between the display screen and the body; along a third direction, the shielding portion and the fixing portion both include an outer surface and an inner surface, the inner surface of the shielding portion is a curved surface, and the thickness of the inner surface of the shielding portion gradually decreases along the direction away from the fixed portion; at least part of the non-display area of ​​the display screen covered (e.g., vertically covered along the third direction) by the shielding portion is curved and has the same shape as the curved surface of the shielding portion; the first direction, the second direction, and the third direction are perpendicular to each other.

[0007] By setting the inner surface of the shielding portion of the screen decorative member to a curved surface, the corresponding non-display area of ​​the display screen corresponding to the shielding portion is also curved. In this way, without changing the size of the shielding portion in the second direction and the distance from the edge of the display screen to the screen decorative member, the shielding portion covers the non-display area of ​​the display screen more widely, and the width of the non-display area exposed to the outside is reduced, which is conducive to achieving a full-screen design for electronic devices. In addition, the screen decorative member and appearance member provided in this application can be assembled vertically (assembled along the third direction), which is suitable for ultra-thin foldable terminals.

[0008] Exemplarily, the first direction, the second direction, and the third direction are perpendicular to each other, that is, the first direction is perpendicular to the second direction, the first direction is perpendicular to the third direction, and the second direction is perpendicular to the third direction.

[0009] Exemplarily, the first direction may be the Y-axis direction, that is, when the electronic device is a foldable terminal, the length direction of the foldable terminal after it is unfolded.

[0010] Exemplarily, the second direction may be an X-axis direction, that is, when the electronic device is a foldable terminal, a width direction of the foldable terminal after it is unfolded.

[0011] Exemplarily, the third direction may be the Z-axis direction, that is, when the electronic device is a foldable terminal, the thickness direction of the foldable terminal after it is unfolded.

[0012] For example, when the electronic device is a foldable terminal, the above-mentioned display screen is a foldable flexible display screen, and when the electronic device is a bar-type terminal, the display screen is a non-foldable non-flexible display screen; of course, it can also be a foldable flexible display screen, but since the electronic device is a bar-type terminal, the display screen is always in a flat state.

[0013] Exemplarily, the outer surface and inner surface included in both the shielding portion and the fixing portion are the inner surface and outer surface of the screen decoration component.

[0014] In a possible implementation of the present application, along the second direction and along the direction in which the fixed portion points to the shielding portion, the vertical distance from the inner surface of the end of the shielding portion away from the fixed portion to the area in the display screen corresponding to the end of the shielding portion gradually increases.

[0015] This arrangement can prevent the edge of the screen decoration component (ie the end of the shielding portion away from the fixing portion) from pressing against the display screen and generating light and shadow.

[0016] For example, since the inner surface of the shielding portion is an arc surface, any point on its inner surface has a corresponding tangent; at least part of the non-display area of ​​the display screen corresponding to the shielding portion is also arc-shaped, and any point on it also has a corresponding tangent. Therefore, the vertical distance from the inner surface of the end of the shielding portion away from the fixed portion to the area of ​​the display screen corresponding to the end of the shielding portion can be understood as: the distance between two points parallel to the tangent (one point is located on the inner surface of the end of the shielding portion away from the fixed portion, and the other point is located in at least part of the non-display area of ​​the display screen corresponding to the shielding portion).

[0017] Illustratively, the vertical distance from the inner surface of the end of the shielding portion away from the fixed portion to the area of ​​the display screen corresponding to the end of the shielding portion can also be understood as: the distance between two points coinciding on the plane formed by the first direction and the second direction (one point is located on the inner surface of the end of the shielding portion away from the fixed portion, and the other point is located in at least a portion of the non-display area of ​​the display screen corresponding to the shielding portion).

[0018] It should be noted that the dimension of the end portion of the shielding portion away from the fixing portion in the second direction can be set by those skilled in the art according to actual conditions.

[0019] In a possible implementation of the present application, the curvature R of the projection of the inner surface of the shielding portion on the plane formed by the first direction and the second direction satisfies: R is less than or equal to 0.5 mm -1 , and greater than or equal to 0.1mm -1 .

[0020] Correspondingly, the curvature r of the projection of the arc-shaped portion of the display screen on the plane formed by the first direction and the second direction also satisfies: r is less than or equal to 0.5 mm -1 , and greater than or equal to 0.1mm -1 In this way, there is no risk of flattening due to excessive curvature of the curved portion of the display screen, nor is there a risk of the visible black border of the obstructed display screen being too narrow due to too small a curvature of the inner surface of the obstructing portion.

[0021] In a possible implementation of the present application, along the second direction, a plurality of spaced-apart clips are provided on the side wall of the fixing portion facing away from the shielding portion (the side wall connecting the inner surface and the outer surface of the fixing portion); the body includes an appearance part, the appearance part includes a blocking portion and a bearing portion extending along the first direction and arranged in the second direction, the fixing portion is fixed on the bearing portion, and along the third direction, the height of the blocking portion is higher than the height of the bearing portion; the portion of the blocking portion that is higher than the bearing portion includes an outer side wall and an inner side wall that are arranged opposite to each other along the second direction, the outer side wall is located on the side of the inner side wall facing away from the bearing portion, and the inner side wall is partially recessed to form a plurality of clips; the plurality of clips are respectively located in the plurality of clips.

[0022] The snap-fitting arrangement of the clips and the slots can fix the screen decoration to the fuselage, preventing the screen decoration from being separated from the fuselage due to a thrust generated on the shielding part of the display screen when the film layer of the display screen is flattened, and the thrust being greater than the adhesive force of the glue between the fixed part of the screen decoration and the fuselage.

[0023] Exemplarily, the side wall of the fixing portion connects the outer surface and the inner surface of the fixing portion.

[0024] In one possible implementation of the present application, the enclosure further includes an upper wall connecting the inner wall and the outer wall, and the connection between the upper wall and the inner wall is configured as an arc. This configuration facilitates the snap-fitting into the slot when the screen decoration is vertically (along the third direction) mounted on the body.

[0025] In a possible implementation of the present application, the fuselage includes an appearance part, the appearance part includes an enclosure part and a load-bearing part extending along a first direction and arranged along a second direction, and the fixing part is fixed on the load-bearing part; along the second direction, a plurality of spaced support ribs are provided on the upper surface of the load-bearing part away from one end of the enclosure part.

[0026] The setting of the supporting ribs can support the screen decoration and prevent the screen decoration from falling to one side due to the center of gravity of the screen decoration moving toward the shielding part during the gluing and pressing process when the fixing part is fixed to the body by gluing.

[0027] In one possible implementation of the present application, the screen decorative member is provided with multiple receiving slots at positions corresponding to the support ribs, and the multiple support ribs are respectively located in the multiple receiving slots. The receiving slots accommodate the support ribs, which facilitates the lightweight design of the electronic device and further prevents the screen decorative member from tilting to one side.

[0028] Illustratively, the receiving groove may be located at the junction of the inner surface of the fixing portion and the inner surface of the shielding portion.

[0029] Exemplarily, a junction between the inner surface of the fixing portion and the inner surface of the shielding portion is partially recessed to form a plurality of accommodating grooves.

[0030] In one possible implementation of the present application, when the fuselage includes an exterior member, the exterior member includes a retaining portion and a load-bearing portion arranged along the second direction, the fixing portion is fixed to the load-bearing portion, and the height of the retaining portion is higher than the height of the load-bearing portion along the third direction; the portion of the retaining portion that is higher than the load-bearing portion includes an outer wall and an inner wall arranged opposite to each other along the second direction, the outer wall is located on the side of the inner wall facing away from the load-bearing portion, and the inner wall is partially recessed to form a plurality of slots, the support ribs and the slots are staggered. This arrangement facilitates the formation of the slots during the process of forming the slots.

[0031] In a possible implementation of the present application, along the first direction, the length of the support rib is greater than or equal to 5 mm.

[0032] In this way, the supporting ribs will not be too short to play a supporting role, nor will the supporting ribs be too long to occupy too much area of ​​the bearing portion, which is not conducive to the fixation of the fixing portion.

[0033] Exemplarily, the length of the support rib is 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc.

[0034] In a possible implementation of the present application, the number of support ribs is greater than or equal to 5.

[0035] This arrangement can better prevent the screen decoration from tilting due to the center of gravity of the screen decoration moving toward the shielding part during the process of gluing and pressing when the fixing part is fixed to the body by gluing.

[0036] Exemplarily, the number of support ribs is 5, 7, or 9, etc.

[0037] In a possible implementation of the present application, a plurality of support ribs are evenly distributed on the upper surface of the end of the bearing portion away from the enclosing portion.

[0038] This arrangement can better support the screen decoration parts and make the force on the screen decoration parts more uniform.

[0039] In one possible implementation of the present application, a support platform is provided on the inner surface of the fixing portion near one end of the shielding portion. The support platform can be formed by a protrusion on the inner surface of the fixing portion near one end of the shielding portion. The provision of the support platform can also support the screen decorative component, preventing the screen decorative component from tilting due to the center of gravity of the screen decorative component shifting toward the shielding portion during the glue dispensing and pressing process when the fixing portion is fixed to the body.

[0040] In one possible implementation of the present application, the screen decorative member further includes an overlapping portion, which is located on a side of the fixing portion facing away from the shielding portion along the second direction. The body includes an exterior member, which includes an enclosure portion and a support portion arranged along the second direction. Along the third direction, the enclosure portion is higher than the support portion. The fixing portion is fixed to the support portion, and the overlapping portion overlaps the enclosure portion. This covers the upper wall of the enclosure portion, thereby enhancing the aesthetics of the electronic device.

[0041] In a possible implementation of the present application, the electronic device includes a foldable terminal. Of course, the electronic device is not limited to a foldable terminal.

[0042] In a possible implementation of the present application, a foldable terminal includes a first body and a second body, and corresponding first and second screen decorations; the foldable terminal also includes a hinge structure; the display screen is a flexible display screen; one end of the hinge structure is connected to the first body, and the other end is connected to the second body; the flexible display screen is located on one side of the hinge structure, the first body, and the second body; the flexible display screen includes a bent display segment and a first and second flat display segments located on both sides of the bent display segment; the screen decoration is located on a side of the flexible display screen away from the first and second bodies; the shielding portion of the first screen decoration covers at least part of the non-display area of ​​the first flat display segment and at least part of the gap between the first flat display segment and the first body; and the shielding portion of the second screen decoration covers at least part of the non-display area of ​​the second flat display segment and at least part of the gap between the second flat display segment and the second body; at least part of the non-display area of ​​the first flat display segment covered by the shielding portion of the first screen decoration is arc-shaped, and / or at least part of the non-display area of ​​the second flat display segment covered by the shielding portion of the second screen decoration is arc-shaped.

[0043] For example, at least part of the non-display area of ​​the first flat display segment covered by the blocking portion of the first screen decorative member may be arc-shaped, or at least part of the non-display area of ​​the second flat display segment covered by the blocking portion of the second screen decorative member may be arc-shaped, or at least part of the non-display area of ​​the first flat display segment covered by the blocking portion of the first screen decorative member may be arc-shaped, and at least part of the non-display area of ​​the second flat display segment covered by the blocking portion of the second screen decorative member may be arc-shaped.

[0060] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0061] The term "and / or" in this article is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0062] In the description and claims of the embodiments of this application, the terms "first" and "second" are used to distinguish different objects, rather than to describe a specific order of objects. For example, the terms "first target object" and "second target object" are used to distinguish different objects, rather than to describe a specific order of objects.

[0063] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0064] In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more. For example, "multiple processing units" means two or more processing units; "multiple systems" means two or more systems.

[0065] In the description of the embodiments of this application, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a rotating connection, a sliding connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to specific circumstances.

[0066] The embodiments of the present application provide an electronic device, which can be a foldable terminal or a bar terminal. The electronic device provided in the embodiments of the present application can be a mobile phone, a tablet computer, a personal digital assistant (PDA), an in-car computer, a television, a smart wearable device, a smart home device, etc. The embodiments of the present application do not specifically limit the specific form of the above electronic devices. For the convenience of explanation, the following description is based on the example of an electronic device being a mobile phone, and the mobile phone being a foldable mobile phone.

[0067] 1 and 2 , FIG1 is a schematic structural diagram of a foldable terminal provided in an embodiment of the present application, and FIG2 is an exploded view of the foldable terminal shown in FIG1 . As shown in FIG1 and FIG2 , a foldable mobile phone 100 includes a flexible display (also referred to as a foldable screen or flexible screen) 10 .

[0068] The flexible display screen 10 may include an organic light emitting diode (OLED) display screen. OLED displays do not require a backlight module, and the base substrate in the OLED display screen may be made of a flexible resin material, such as polyethylene terephthalate (PET), so that the OLED display screen has a bendable property. Of course, the types of flexible display screens 10 include but are not limited to OLED displays. As long as the display screen can be bent, it is within the scope of protection of this application. For example, it may also be a liquid crystal display (LCD) screen, an LED display screen (which may include a Micro-LED display screen, a Mini-LED display screen), etc.

[0069] It should be noted that, to facilitate a clear description of the subsequent structural features and their positional relationships, the positional relationships of the various structures within the foldable phone 100 are defined using the X-axis, Y-axis, and Z-axis directions. The X-axis direction represents the width of the unfolded foldable phone 100, the Y-axis direction represents the length of the unfolded foldable phone 100, and the Z-axis direction represents the thickness of the unfolded foldable phone 100.

[0070] Continuing with Figures 1 and 2 , the foldable phone 100 further includes a first body 20, a second body 30, and a hinge structure 40. Along the X-axis, the first body 20 and the second body 30 are located on either side of the hinge structure 40, and the hinge structure 40 is connected to the first body 20 and the second body 30, respectively. The first body 20, the hinge structure 40, and the second body 30 can be used to support the flexible display 10. The first body 20 and the second body 30 can each rotate about the axis S0 of the hinge structure 40, thereby driving the flexible display 10 to fold or unfold, thereby achieving folding or unfolding of the foldable phone 100. In some embodiments, the first body 20 and the second body 30 are symmetrically arranged about the axis S0.

[0071] The flexible display 10 can be divided into different sections. When folded, the portion of the flexible display 10 that bends is the curved display segment 12. Along the X-axis, the sections of the flexible display 10 located on either side of the curved display segment 12 are the first flat display segment 11 and the second flat display segment 13. As the foldable phone 100 moves from the unfolded state to the folded state, the angle between the plane containing the first flat display segment 11 and the plane containing the second flat display segment 13 changes as the curved display segment 12 bends, for example, from 180° to 0°.

[0072] It should be noted that the foldable mobile phone 100 of the embodiment of the present application is an inward-folding foldable mobile phone, that is, when folded, the first body 20 and the second body 30 are folded toward the light emitting direction of the flexible display screen 10.

[0073] It should also be noted that the foldable phone 100 can fold at multiple positions. Accordingly, the foldable phone 100 may include multiple hinge structures 40 and multiple bodies. For example, it may include two hinge structures 40 and three bodies, with adjacent bodies connected by a hinge structure 40. In this way, the foldable phone 100 has two folded positions. As can be seen, the foldable phone 100 includes at least one hinge structure 40 and at least two bodies, with adjacent bodies connected by a hinge structure 40. For ease of explanation, the embodiments of this application are described using the example of a foldable phone 100 including one hinge structure 40 and two bodies (i.e., a first body 20 and a second body 30).

[0074] It should also be noted that the drawings related to the hinge structure 40 of the embodiment of the present application are simplified schematic diagrams. The embodiment of the present application does not limit the specific structure of the hinge structure 40, as long as it can achieve the rotation of the first body 20 and the second body 30, thereby achieving the folding or unfolding state of the foldable mobile phone 100. For example, the hinge structure 40 includes a shaft cover, a synchronization mechanism, a door panel, a damping mechanism, and other structures known to those skilled in the art. The specific structure and corresponding relationships can be referred to in the prior art and will not be repeated here.

[0075] It should also be noted that Figures 1 and 2 illustrate the foldable phone 100 as folded longitudinally (i.e., in the Y-axis direction), i.e., forming two left and right screens when folded, but this does not constitute a limitation of the present application. In other optional embodiments of the present application, the foldable phone 100 can also be folded transversely (i.e., in the X-axis direction), i.e., forming two upper and lower screens when folded. The following description uses the foldable phone 100 folded longitudinally as an example.

[0076] 3 , which is a cross-sectional view of the foldable terminal shown in FIG1 at line AA′. As shown in FIG2 and FIG3 , the first body 20 includes a first housing 21 and a first middle frame 22. The second body 30 includes a second housing 31 and a second middle frame 32.

[0077] The first housing 21 can be the back cover (also called the battery cover) of the foldable phone 100, or a display screen (such as an LCD, OLED, or LED display), which is not limited in this embodiment. The second housing 31 can be the back cover (also called the battery cover) of the foldable phone, or a display screen, which is not limited in this embodiment.

[0078] The first middle frame 22 includes a first appearance member (the exposed structure of the first middle frame 22) 221 and a first support member 222 located between the first flat display segment 11 and the first outer shell 21. The first appearance member 221 is fixedly connected to the first support member 222. The first appearance member 221 and the first support member 222 can be integrally formed or separately formed and then secured together by welding or bonding. The second middle frame 32 includes a second appearance member (the exposed structure of the second middle frame 32) 321 and a second support member 322 located between the second flat display segment 13 and the second outer shell 31. The second appearance member 321 and the second support member 322 are fixedly connected. The second appearance member 321 and the second support member 322 can be integrally formed or separately formed and then secured together by welding or bonding. In addition, along the Z-axis direction, the first appearance member 221 includes a first upper sidewall 221 a and a first lower sidewall 221 b opposite to each other, and the second appearance member 321 includes a second upper sidewall 321 a and a second lower sidewall 321 b opposite to each other.

[0079] The first flat display segment 11 of the flexible display 10, the first exterior member 221, and the first housing 21 form a first housing cavity 23. The second flat display segment 13 of the flexible display 10, the second exterior member 321, and the second housing 31 form a second housing cavity 33. The first and second housing cavities 23 and 33 contain structures such as a printed circuit board, a flexible circuit board, functional components, and a battery (not shown). These functional components include, for example, a processing module and a voltage conversion module. The flexible display 10 and certain structures within the housing cavities are supported by the first support member 222 of the first middle frame 22 and the second support member 322 of the second middle frame 32. For example, see Figure 4, which is a partial enlarged view of the WW region in Figure 3. As shown in Figure 4, the flexible display 10 can be bonded to the first support member 222 of the first middle frame 22 and the second support member 322 of the second middle frame 32 (not shown in Figure 4) using adhesive 60, thereby supporting the flexible display 10 via the first support member 222 and the second support member 322. In some embodiments, along the Z-axis, the flexible display 10 may include a polarizer 11, a display unit 12, and a supporting backing film 13. The display unit 12 is located between the polarizer 11 and the supporting backing film 13, and is also located on the side of the supporting backing film 13 facing away from the first support member 222 and the second support member 322. Of course, the flexible display 10 may also include only the display unit 12; or, the flexible display 10 may include both the display unit 12 and the supporting backing film 13, which is not limited in this embodiment of the present application. The supporting backing film 13 is used to support the display unit 12 and prevent damage during transfer and transportation. The provision of the polarizer 11 can improve the contrast of the flexible display 10. In some embodiments, the flexible display 10 also includes a cover plate 14. Along the Z-axis, the cover plate 14 is located on the side of the polarizer 11 facing away from the display unit 12. The cover plate 14 can protect the display 10 and improve its scratch resistance and impact resistance. In some embodiments, the flexible display 10 further includes a protective film 15. Along the Z-axis, the protective film 15 is located on the side of the cover plate 14 facing away from the polarizer 11. The protective film 15 can protect the cover plate 14. In some embodiments, the flexible display 10 further includes a heat dissipation film 16 located on the side of the supporting backing film 13 facing away from the display unit 12. The heat dissipation film 16 is bonded to the first support member 222 and the second support member 322 via an adhesive 60.

[0080] Continuing to refer to Figures 2 to 4, the foldable mobile phone 100 also includes a screen decoration 50. Along the Z-axis direction, the screen decoration 50 is located on the side of the flexible display screen 10 facing away from the body, and is used to cover the gap between the flexible display screen 10 and the appearance parts, that is, to cover the gap between the first appearance part 221 and the edge of the first flat display segment 11, and to cover the gap between the second appearance part 321 and the edge of the second flat display segment 13.

[0081] Referring to Figure 5 , which is a schematic diagram of the front structure of a screen decoration member provided in an embodiment of the present application, as shown in Figure 5 , the screen decoration member 50 can be a non-enclosed annular structure. For example, the shape of the screen decoration member 50 is, for example, a "C" shape, i.e., the projection of the screen decoration member 50 on the plane formed by the X-axis and the Y-axis when the flexible display screen 10 is in the unfolded state is a "C" shape.

[0082] Exemplarily, the screen decorative member 50 includes a first decorative segment 50a and two second decorative segments 50b. The two second decorative segments 50b extend in the same direction, for example, both extend in the X-axis direction. The extension direction of the first decorative segment 50a is different from the extension direction of the second decorative segment 50b. For example, the extension direction of the first decorative segment 50a is the Y-axis direction. The two second decorative segments 50b are arranged opposite each other along the Y-axis direction, with the first decorative segment 50a located between the two second decorative segments 50b. The screen decorative member 50 also includes two curved segments 50d, namely a first curved segment 50d1 and a second curved segment 50d2. The first curved segment 50d1 is used to connect one end of the first decorative segment 50a and one end of one of the second decorative segments 50b, so that the first decorative segment 50a and the second decorative segment 50b are smoothly connected. The second curved segment 50d2 is used to connect the other end of the first decorative segment 50a and one end of the other second decorative segment 50b, so that the first decorative segment 50a and the second decorative segment 50b are smoothly connected.

[0083] For example, referring again to Figures 2 and 3 , there are two screen decorative members 50, namely a first screen decorative member 53 and a second screen decorative member 54. Along the Z-axis, the first screen decorative member 53 is located on the side of the first upper sidewall 221a facing away from the first lower sidewall 221b, and is used to block the gap between the first appearance member 221 and the edge of the first flat display segment 11 of the flexible display screen 10. Along the Z-axis, the second screen decorative member 54 is located on the side of the second upper sidewall 321a facing away from the second lower sidewall 221b, and is used to block the gap between the second appearance member 321 and the edge of the second flat display segment 13 of the flexible display screen 10. In some embodiments, the first screen decorative member 53 and the second screen decorative member 54 are symmetrically distributed about the axis S0.

[0084] For example, referring to Figures 4 and 5 , the first screen decorative member 53 and the second screen decorative member 54 each include a fixing portion 51 and a shielding portion 52. The shielding portion 52 and the fixing portion 51 are both non-enclosed annular structures, and the fixing portion 51 is arranged around the shielding portion 52. For example, the shielding portion 52 and the fixing portion 51 are both shaped like a "C". The shielding portion 52 and the fixing portion 51 can be integrally formed and fixedly connected. Of course, the shielding portion 52 and the fixing portion 51 can also be formed separately and fixed together by welding or bonding. The fixing portion 51 of the first screen decoration 53 is used to fix the first screen decoration 53 on the first appearance part 221, so that the covering portion 52 of the first screen decoration 53 covers the gap between the first appearance part 221 and the edge of the first flat display segment 11. The fixing portion 51 of the second screen decoration 54 is used to fix the second screen decoration 54 on the second appearance part 321, so that the covering portion 52 of the second screen decoration 54 covers the gap between the second appearance part 321 and the edge of the second flat display segment 13.

[0085] Along the Z-axis direction, the first screen decoration 53 and the second screen decoration 54 both include relative outer surfaces 50f and inner surfaces 50g. The outer surface 50f of the first screen decoration 53 is located on the side of the inner surface 50g away from the first upper side wall 221a of the first appearance part 221, and the outer surface 50f of the second screen decoration 54 is located on the side of the inner surface 50g away from the second upper side wall 321a of the second appearance part 321.

[0086] For example, see FIG6 , which is a schematic diagram of the back structure of a screen decoration member provided in an embodiment of the present application. As shown in FIG4 and FIG6 , the inner surface 50g of the screen decoration member 50 is partially recessed along the Z-axis near the edge of the flexible display screen 10, forming a non-enclosed annular notch 50h. The portion of the screen decoration member 50 corresponding to the annular notch 50h is a shielding portion 52. That is, along the Z-axis, the orthographic projection of the annular notch 50h on the plane formed by the X-axis and the Y-axis coincides with the orthographic projection of the shielding portion 52 on the plane formed by the X-axis and the Y-axis. The remaining portion of the screen decoration member 50, excluding the shielding portion 52, is a fixing portion 51.

[0087] The annular notch 50h is arranged so that the thickness of the shielding portion 52 is less than the thickness of the fixing portion 51 along the Z-axis direction. In this way, the edge of the flexible display screen 10 can extend into the annular notch 50h, so that the shielding portion 52 can block the gap between the edge of the flexible display screen 10 and the appearance component, and protect the edge of the flexible display screen 10. Specifically, as shown in Figure 4, the flexible display screen 10 includes a display area AA and a non-display area NAA arranged around the display area AA. The display area AA is provided with a plurality of pixels arranged in an array, and the non-display area NAA is provided with a driving circuit for driving the plurality of pixels in the display area AA to display. The non-display area NAA includes a first non-display area (also called a visible black border) NAA1 and a second non-display area (also called a blocking black border) NAA2. The first non-display area NAA1 is provided around the display area AA, and the second non-display area NAA2 is provided around the first non-display area NAA1. The second non-display area NAA2 of the flexible display screen 10 can extend into the annular gap 50h (the gap 50h extending into the annular gap is generally other film layers of the flexible display screen 10 except the protective film 15) so as to shield the second non-display area NAA2 of the flexible display screen 10 and the gap between the flexible display screen 10 and the appearance part through the shielding part 52, and protect the edge of the flexible display screen 10.

[0088] Continuing to refer to Figures 3 and 5, in some embodiments, the inner surface 50g of the fixing portion 51 is partially raised along the Z-axis direction to form at least one raised portion 511. Correspondingly, the upper side wall of the appearance part is partially recessed to form a recessed portion that matches the raised portion 511. The raised portion 511 is embedded in the recessed portion so that the fixing portion 51 of the screen decorative part 50 is fixed to the appearance part. Exemplarily, the first upper side wall 221b of the first appearance part 221 is partially recessed to form a recessed portion that is compatible with the raised portion 511 corresponding to the fixing portion 51 of the first screen decorative part 53, and the raised portion 511 is embedded in the recessed portion so that the fixing portion 51 of the first screen decorative part 53 is fixed to the first appearance part 221. For example, the fixing portion 51 can be fixed to the first appearance part 221 by an interference fit between the raised portion 511 and the recessed portion, or the fixing portion 51 of the first screen decorative part 53 can be fixed to the first appearance part 221 by bonding (glue or other sticky materials). Similarly, the second upper side wall 321b of the second appearance part 321 is partially recessed to form a recessed portion that is compatible with the raised portion 511 corresponding to the fixing portion 51 of the second screen decoration part 54. The raised portion 511 is embedded in the recessed portion so that the fixing portion 51 of the second screen decoration part 54 is fixed to the second appearance part 321. For example, the fixing portion 51 can be fixed to the second appearance part 321 by means of an interference fit between the raised portion 511 and the recessed portion, or the fixing portion 51 of the second screen decoration part 54 can be fixed to the second appearance part 321 by means of bonding (glue or other sticky materials).

[0089] It should be noted that the number of the above-mentioned raised portion 511 can be one, and the raised portion 511 can be a semi-enclosed annular raised portion 511. Of course, the number of raised portions 511 can be multiple, and the multiple raised portions 511 can be evenly distributed on the inner surface 50g, so that the fixing portion 51 of the screen decorative member 50 is more stably fixed to the appearance member.

[0090] As can be seen from the foregoing, the obstruction 52 only blocks the second non-display area NAA2 of the flexible display screen 10, leaving the first non-display area NAA1 exposed. This means that the obstruction 52 only partially blocks the non-display area NAA of the flexible display screen 10, hindering the full-screen design of the foldable phone 100. To reduce the width of the first non-display area NAA1 without reducing the overall width of the non-display area NAA, the screen decorative member 50 must be used to shield the first non-display area NAA1 of the flexible display screen 10. The larger the shielding width, the better. Increasing the shielding width of the screen decorative member 50 can include: 1. increasing the width of the obstruction 52 of the screen decorative member 50; 2. Maintaining the width of the obstruction 52 of the screen decorative member 50, while moving the first non-display area NAA1 below the obstruction 52, so that the obstruction 52 not only blocks the second non-display area NAA2 but also at least a portion of the first non-display area NAA1. However, since the shielding portion 52 of the screen decoration member 50 is a relatively thin cantilever, increasing the width of the shielding portion 52 of the screen decoration member 50 will result in a loss of strength and processing yield. If the width of the blocking portion 52 of the screen decoration 50 remains unchanged, at least part of the first non-display area NAA1 in Figure 4 moves to the bottom of the blocking portion 52, and the distance H0 from the edge of the flexible display screen 10 to the fixing portion 51 of the screen decoration 50 becomes smaller. When folded, the edge of the flexible display screen 10 will move toward the fixing portion 51, and the flexible display screen 10 may interfere with the screen decoration 50, especially the four corners of the flexible display screen 10 (such as the EE area in Figure 1) interfere with the fixing portion 51 at the first curved section 50d1 and the second curved section 50d2 of the first screen decoration 53 and the fixing portion 51 at the first curved section 50d1 and the second curved section 50d2 of the second screen decoration 54, respectively, causing damage to the flexible display screen 10; and the distance H1 from the protective film 15 of the flexible display screen 10 to the blocking portion 52 becomes smaller. When folded, the edge of the protective film 15 will move toward the blocking portion 52, interfering with the screen decoration 50, causing the protective film 15 to warp.

[0091] Based on this, the embodiment of the present application further improves the screen decorative member 50 and the first and second middle frames 22 and 32. While maintaining the distance H0 between the edge of the flexible display 10 and the fixing portion 51 of the screen decorative member 50, the width of the first non-display area NAA1 exposed to the outside is reduced, facilitating the full-screen design of the foldable phone 100. The improved screen decorative member and middle frame are described below. It should be noted that the improvement of the screen decoration 50 includes improving only the first decoration segment 50a of the screen decoration 50, and accordingly, it is necessary to improve the position of the first middle frame 22 corresponding to the first decoration segment 50a of the first screen decoration 53, and the position of the second middle frame 32 corresponding to the first decoration segment 50a of the second screen decoration 54; it is also possible to improve only the second decoration segment 50b of the screen decoration 50, and accordingly, it is necessary to improve the position of the first middle frame 22 corresponding to the second decoration segment 50b of the first screen decoration 53, and the position of the second middle frame 32 corresponding to the second decoration segment 50b of the second screen decoration 54; it is also possible to improve the screen Both the first decorative segment 50a and the second decorative segment 50b of the curtain decoration 50 are improved. Accordingly, it is necessary to improve the positions in the first middle frame 22 corresponding to the first decorative segment 50a and the second decorative segment 50b of the first screen decoration 53, as well as the positions in the second middle frame 32 corresponding to the first decorative segment 50a and the second decorative segment 50b of the second screen decoration 54. The following content is explained by taking the improvement of the first decorative segment 50a of the screen decoration 50, as well as the improvement of the position in the first middle frame 22 corresponding to the first decorative segment 50a of the first screen decoration 53, as well as the improvement of the position in the second middle frame 32 corresponding to the first decorative segment 50a of the second screen decoration 54 as an example.

[0092] Referring to Figures 7 and 8, Figure 7 is a partial structural schematic diagram of a foldable terminal provided in an embodiment of the present application, and Figure 8 is a partial enlarged view of the UU area in Figure 7. The foldable mobile phone 100 in Figure 7 only shows the flexible display screen 10 and the first body 20, and does not show the second body 30, but the improvements of the second body 30 are the same as those of the first body 20. The following content is explained by taking the improvement of the first decorative segment 50a of the first screen decoration 53 and the improvement of the position corresponding to the first decorative segment 50a of the first screen decoration 53 in the first middle frame 22 as an example. The improvement of the first decorative segment 50a of the second screen decoration 54 is the same as the improvement of the first decorative segment 50a of the first screen decoration 53, and the improvement of the position corresponding to the first decorative segment 50a of the second screen decoration 54 in the second middle frame 32 is the same as the improvement of the position corresponding to the first decorative segment 50a of the first screen decoration 53 in the first middle frame 22. The following content will not be repeated. As shown in Figures 7 and 8, the first exterior member 221 includes a blocking portion 223 and a supporting portion 224. Along the X-axis, the blocking portion 223 is located on the side of the supporting portion 224 facing away from the rotating shaft structure 40. Along the Z-axis, the height of the blocking portion 223 is higher than the height of the supporting portion 224 to block the supporting portion 224.

[0093] Referring to FIG9 , FIG9 is a schematic diagram of the back structure of the screen decoration provided in an embodiment of the present application at an angle, FIG10 is a partial enlarged view of the VV area of ​​the screen decoration shown in FIG9 , and FIG11 is a cross-sectional view of the foldable terminal shown in FIG1 at position BB'. As shown in FIG9-11 , the screen decoration 50 still includes a fixing portion 51 and a shielding portion 52, but the fixing portion 51 and the shielding portion 52 of the first decorative segment 50a of the screen decoration 50 in this example have different structures from the fixing portion 51 and the shielding portion 52 in the above content (such as the fixing portion 51 and the shielding portion 52 shown in FIG3-6 ). Specifically, referring to FIG7-11 , along the X-axis direction, the fixing portion 51 is located on the side of the shielding portion 52 away from the rotating shaft structure 40. The fixing portion 51 is fixed to the bearing portion 224 to fix the first screen decoration 53 to the first appearance member 221. For example, the fixing portion 51 can be fixed to the supporting portion 224 by dispensing glue, and the fixing portion 51 can be enclosed by the enclosing portion 223 located outside the fixing portion 51 to prevent the fixing portion 51 and the glue that fixes the fixing portion 51 to the supporting portion 224 from being exposed and affecting the appearance of the foldable mobile phone 100. The inner surface 50g of the shielding portion 52 is configured as a curved surface, and the thickness of the shielding portion 52 gradually decreases along the X-axis and away from the fixing portion 51. Correspondingly, the flexible display 10 extending below the shielding portion 52 is also curved, where extending below the shielding portion 52 refers to the position of the flexible display 10 relative to the shielding portion 52 when the foldable mobile phone 100 is placed flat and the flexible display 10 is facing upward (towards the user). For example, the surface of the first support member 222 that contacts the flexible display 10 and is proximate to the first exterior member 221 is also curved. Accordingly, the predetermined area of ​​the flexible display 10 is also curved. The predetermined area of ​​the flexible display 10 includes at least the non-display area NAA extending along the Y-axis of the flexible display 10 (i.e., the non-display area located in the first flat display segment 11 and the non-display area located in the second flat display segment 13). It is understood that, due to the inherent flexibility of the flexible display 10, no special design is required for the flexible display 10. Simply positioning the predetermined area of ​​the flexible display 10 in the curved area on the first support member 222 can achieve a curved shape in the predetermined area of ​​the flexible display 10. Furthermore, the shape of the film layer corresponding to the curved surface of the shielding portion 52 in the predetermined area of ​​the flexible display 10 is identical to the shape of the curved surface of the shielding portion 52, and their trends are consistent. The film layer corresponding to the curved surface of the shielding portion 52 is the curved surface of the shielding portion 52 on the plane formed by the X-axis and the Y-axis. The consistent trends are defined as follows: The film layer covered by the projection on the flexible display screen 10.The inner surface 50g of the shielding portion 52 is set to be a curved surface, and accordingly, the non-display area NAA in the flexible display screen 10 is also curved. In this way, without changing the size of the shielding portion 52 in the X-axis direction, and without changing the distance H0 from the edge of the flexible display screen 10 to the first screen decorative member 53, the width of the shielding portion 52 blocking the non-display area NAA of the first flat display segment 11 is increased, that is, the width of the second non-display area NAA2 (in the X-axis direction) is increased, and the width of the first non-display area NAA1 (in the X-axis direction) is reduced, that is, the width of the first non-display area NAA1 exposed to the outside is reduced, which is conducive to realizing the full-screen design of the foldable mobile phone 100.

[0094] That is to say, the shielding portion 52 of the first screen decoration member 53 can not only cover the gap between the first appearance member 221 and the edge of the first flat display segment 11 , but also facilitate the full-screen design of the foldable mobile phone 100 .

[0095] In some embodiments, the curvature R of the projection of the inner surface of the shielding portion 52 on the plane formed by the X-axis direction and the Y-axis direction satisfies: R is less than or equal to 0.5 mm -1 , and greater than or equal to 0.1mm -1 Correspondingly, the curvature r of the projection of the arc-shaped portion of the flexible display screen 10 on the plane formed by the X-axis direction and the Y-axis direction also satisfies: r is less than or equal to 0.5 mm -1 , and greater than or equal to 0.1mm -1 The curvature of the inner surface of the shielding portion 52 is used to indicate the degree of curvature of the inner surface of the shielding portion 52 , and the curvature of the curved portion of the flexible display screen 10 is used to indicate the degree of curvature of the curved portion of the flexible display screen 10 .

[0096] For example, the curvature R of the projection of the inner surface of the shielding portion 52 on the plane formed by the X-axis direction and the Y-axis direction is 0.1 mm. -1 , 0.2mm -1 , 0.3mm -1 , 0.4mm -1 or 0.5mm -1 The curvature r of the projection of the curved portion of the flexible display 10 on the plane formed by the X-axis direction and the Y-axis direction is 0.1 mm -1 , 0.2mm -1 , 0.3mm -1 , 0.4mm -1 or 0.5mm -1 .

[0097] The curvature R of the projection of the inner surface of the shielding portion 52 on the plane formed by the X-axis direction and the Y-axis direction is 0.1 mm. -1 ~0.5mm -1The curvature r of the projection of the arc-shaped portion of the flexible display screen 10 on the plane formed by the X-axis direction and the Y-axis direction is 0.1 mm. -1 ~0.5mm -1 In this case, there is no risk of flattening due to excessive curvature of the curved portion of the flexible display screen 10 , nor is there a risk of the visible black border of the screen being blocked being too narrow due to excessive curvature of the inner surface of the blocking portion 52 .

[0098] In some embodiments, referring again to Figures 7-11 , the first screen decoration member 53 further includes an overlapping portion 55. Along the X-axis, the overlapping portion 55 is located on the side of the fixing portion 51 facing away from the shielding portion 52. The portion of the enclosure portion 223 that is higher than the bearing portion 224 includes an outer sidewall 2231 and an inner sidewall 2232 that are disposed opposite each other along the X-axis. The enclosure portion 223 further includes an upper wall 2233 connecting the outer sidewall 2231 and the inner sidewall 2232. The overlapping portion 55 overlaps the upper wall 2233 of the enclosure portion 223, covering the upper wall 2233 of the enclosure portion 223, thereby enhancing the aesthetic appearance of the foldable phone 100.

[0099] In some embodiments, referring to FIG12 , which is a partial enlarged view of the RR region in FIG11 , as shown in FIG12 , the gap between the inner surface 50 g of the end of the shielding portion 52 away from the fixing portion 51 and the region of the flexible display 10 corresponding to the curved surface of the shielding portion 52 is shaped like a bell mouth. That is, along the X-axis and in a direction away from the fixing portion 51, the vertical distance H2 from the inner surface 50 g of the end of the shielding portion 52 away from the fixing portion 51 to the region of the flexible display 10 corresponding to the end of the shielding portion 52 gradually increases. In other words, the gap between the inner surface 50 g of the end of the shielding portion 52 and the region of the flexible display 10 corresponding to the end of the shielding portion 52 is relatively large.

[0100] This arrangement can prevent the edge of the screen decoration member 50 (ie, the end of the shielding portion 52 away from the fixing portion 51) from pressing against the flexible display screen 10 and generating light and shadow.

[0101] Based on the foregoing, the shapes of the film layers (e.g., polarizer 11, display unit 12, supporting backing film 13, cover plate 14, and heat dissipation film 16) in the predetermined region of flexible display 10 corresponding to the curved surface of shielding portion 52 are identical to the curved surface of shielding portion 52, i.e., all are arc-shaped. When this region of flexible display 10 is arc-shaped, it experiences a flattening stress. Although the first flat display segment 11 of the flexible display screen 10 has been fixed to the first support member 222 by the back glue 60, since the flexible display screen 10 has more film layers, the film layers that are positioned upward (along the Z axis and away from the first support member 222) are easier to flatten. When the film layers of the flexible display screen 10 are flattened, a thrust will be generated on the shielding portion 52 thereon. This thrust may cause the screen decorative member 53 to separate from the first appearance member 221, that is, the thrust is greater than the adhesive force of the glue between the fixing portion 51 of the first screen decorative member 53 and the bearing portion 224 of the first appearance member 221, causing the first screen decorative member 53 to separate from the first appearance member 221.

[0102] Therefore, in some embodiments, referring to Figures 13 and 14, Figure 13 is a schematic diagram of the back structure of the screen decoration provided by the embodiment of the present application at another angle, and Figure 14 is a partial enlarged view of the SS area in the screen decoration shown in Figure 13. As shown in Figures 13 and 14, along the X-axis direction, a plurality of clips 56 are provided on the side wall of the fixing portion 51 away from the shielding portion 52, and the plurality of clips 56 are arranged at intervals, such as the plurality of clips 56 are evenly distributed on the side wall of the shielding portion 52. The clips 56 and the fixing portion 51 can be integrally formed (e.g., the side wall of the fixing portion 51 away from the shielding portion 52 is partially raised to form a plurality of clips 56) and fixedly connected. Of course, the clips 56 and the fixing portion 51 can also be formed separately and fixed together by welding or bonding.

[0103] Continuing with Figure 8 , the inner sidewall 2232 of the enclosure 223 is partially recessed to form multiple latching slots 226. In conjunction with Figure 15 , which shows a cross-sectional view of the foldable terminal shown in Figure 1 at position CC', multiple latches 56 are positioned within the latching slots 226. The restraint provided by the latches 56 in the latching slots 226 further secures the first screen decorative member 53 to the first exterior member 221, preventing the first screen decorative member 53 from becoming detached from the first exterior member 221.

[0104] It is understood that the screen decorative member 50 can generally be made of a plastic material such as polycarbonate (PC), which has high hardness and strength while still having a certain degree of elasticity and deformability. Therefore, during installation, the first screen decorative member 53 only needs to be placed perpendicularly on the first exterior member 221 along the Z-axis. The buckle 56 is then deformed and placed in the slot 226 to restore its original shape.

[0105] On this basis, referring to Figure 16, which is a schematic diagram of the inner side wall and upper wall of the enclosure provided in an embodiment of the present application, as shown in Figure 16, in order to facilitate the buckle 56 to be set in the slot 226, the connection between the inner side wall 2232 and the upper wall 2233 is set to be arc-shaped.

[0106] In some embodiments, referring again to Figures 7 and 8 , a plurality of support ribs 225 are disposed on the upper surface of the support portion 224 at one end thereof distal from the enclosing portion 223 along the X-axis. The plurality of support ribs 225 are spaced apart, such as being evenly distributed across the upper surface of the support portion 224. For example, the number of support ribs 225 can be greater than or equal to five, such as five support ribs 225 evenly distributed across the upper surface of the support portion 224; seven support ribs 225 evenly distributed across the upper surface of the support portion 224; or nine support ribs 225 evenly distributed across the upper surface of the support portion 224. The support ribs 225 and the support portion 224 can be integrally formed and fixedly connected. Alternatively, the support ribs 225 and the support portion 224 can be formed separately and secured together by welding or bonding.

[0107] 9-11 , a plurality of accommodating grooves 57 are provided at positions of the screen decorative member 50 corresponding to the support ribs 225 , that is, the projections of the plurality of accommodating grooves 57 on the bearing portion 224 respectively cover the plurality of support ribs 225 , and the plurality of support ribs 225 are respectively located in the plurality of accommodating grooves 57 .

[0108] The setting of the support rib 225 can support the screen decoration part 50 and prevent the screen decoration part 50 from falling to one side due to the center of gravity of the screen decoration part 50 moving toward the shielding part 52 during the glue-dispensing and pressing process when the fixing part 51 is fixed to the bearing part 224 by glue-dispensing.

[0109] In some embodiments, referring again to FIG8 , the length H3 of the support rib 225 along the Y-axis is greater than or equal to 5 mm. This ensures that the support rib 225 is neither too short to provide support nor too long to occupy too much area of ​​the support portion 224 and hinder the fixing of the fixing portion 51.

[0110] In some embodiments, referring to Figure 8 , the support ribs 225 and the slots 226 are staggered, that is, the projection of each support rib 225 on the plane formed by the Y-axis and the Z-axis is located between the projections of the two adjacent slots 226 on the plane formed by the Y-axis and the Z-axis. Except for the first slot 226 and the last slot 226 (the slots 226 at both ends of the multiple slots 226 arranged along the Y-axis direction), the projection of each of the remaining slots 226 on the plane formed by the Y-axis and the Z-axis is located between the projections of the two adjacent support ribs 225 on the plane formed by the Y-axis and the Z-axis, so as to facilitate the formation of the slots 226.

[0111] In some embodiments, referring to Figure 10, a support platform 58 is provided on the inner surface 50g of the fixing portion 51 near the shielding portion 52. The support platform 58 can be formed by a protrusion on the inner surface 50g of the fixing portion 51 near the shielding portion 52. The setting of the support platform 58 can also support the screen decoration 50 to prevent the fixing portion 51 from being fixed to the bearing portion 224 by gluing. During the gluing and pressing process, the center of gravity of the screen decoration 50 moves toward the shielding portion 52, causing the screen decoration 50 to fall to one side.

[0112] It can be understood that the provision of the plurality of receiving grooves 57 enables the support platform 58 to be divided into a plurality of support units 581 .

[0113] In summary, by setting the inner surface 50g of the shielding portion 52 as a curved surface, the non-display area NAA of the flexible display screen 10 is also curved. In this way, without changing the width of the shielding portion 52 and the distance between the flexible display screen 10 and the screen decoration 50, the width of the non-display area NAA of the flexible display screen 10 blocked by the shielding portion 52 is increased, and the width of the non-display area exposed to the outside is reduced, which is conducive to achieving a full-screen design for the foldable mobile phone 100. In addition, the screen decoration 50 and the appearance part provided in the embodiment of the present application can be assembled in a vertical assembly manner, which is suitable for ultra-thin foldable terminals.

[0114] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
