Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic devices, and more particularly to a display component and an electronic device. Background Art

[0002] With the development of flexible display technology, flexible screens have the characteristic of being bendable and flexible compared to traditional rigid screens, and displaying through flexible screens has become the development trend of future display devices. Due to the flexibility of flexible screens, flexible screens can be applied to a variety of scenarios during use. For example, when a flexible screen is applied to a full display scenario, the edge of the flexible screen will bend, and the curved surface of the support supporting the flexible screen will fit the curved edge of the flexible screen and support the edge of the flexible screen. However, when the flexible screen is bent, due to the elastic deformation of the flexible screen, outward tension will be generated inside it, which may cause the curved edge of the flexible screen to separate from the fitting of the curved surface. Therefore, the current simple dispensing and adhesive bonding technology cannot fix the curved edge of the flexible screen to the curved surface of the support well.

[0003] In order to solve the above problems, one solution is to cover the surface of the flexible screen with a rigid cover plate to fix the curved edge of the flexible screen and the curved surface of the support, so that the screen of the display device with the flexible screen is equivalent to a rigid screen. Another solution is to directly use a flat flexible cover plate. If the flexible screen is in a flat display state, the flexible cover plate and the flexible screen are fixed in a flat manner, and the flexible screen is in a flat unfolded state without internal stress. However, this design has a relatively small screen-to-body ratio. Summary of the invention

[0004] The embodiments of the present application provide a display component and an electronic device, which realize arc surface fixation of a flexible cover plate and a flexible screen, thereby improving the screen-to-body ratio.

[0005] In a first aspect, an embodiment of the present application provides a display assembly, including a screen assembly, a rigid cover plate, and a support member;

[0006] The screen assembly includes a flexible screen and a flexible cover plate, wherein the flexible cover plate covers the flexible screen;

[0007] The support member is used to support the flexible screen;

[0008] The edge of the flexible screen has a first extension portion, and the outer surface of the first extension portion is an arc-shaped surface;

[0009] The edge of the flexible cover plate has a second extension portion, the inner surface of the second extension portion is an arc-shaped surface, the arc-shaped surface of the outer surface of the first extension portion matches at least a part of the arc-shaped surface of the inner surface of the second extension portion, and the second extension portion covers the first extension portion;

[0010] The edge of the support member has a first side surface in the form of an arc-shaped surface, the arc-shaped surface of the first side surface matches the arc-shaped surface of the inner surface of the first extension portion, and the first extension portion covers the first side surface; the rigid cover plate covers at least part of the second extension portion and at least part of the support member. The first extension portion is pressed by the second extension portion, the rigid cover plate covers at least part of the edge of the support member, the rigid cover plate covers at least part of the second extension portion, and the rigid cover plate presses the second extension portion. In this way, when the electronic device is in a folded or bent state, the reverse elastic force generated by the first extension portion of the flexible screen will be offset by the rigid cover plate through the second extension portion, preventing the screen assembly from being detached from the support portion due to the tension of the flexible screen. When the first extension portion of the flexible screen is attached to the first side surface in a bent state, the first extension portion of the flexible screen is protected to prevent the flexible screen from being arched due to bending or folding. The first extension portion can perform an arc display, increasing the screen-to-body ratio.

[0011] In a possible implementation of the first aspect, the edge of the support member further has a second side surface, the second side surface matches at least a portion of the inner surface of the second extension portion, and the second extension portion covers the second side surface. In this way, the distance that the second extension portion extends outward from the flexible cover plate is greater than the distance that the first extension portion extends outward from the flexible screen, so that the second extension portion can effectively press the first extension portion.

[0012] In a possible implementation of the first aspect, the second side surface is an arc-shaped surface, so that the second side surface can be closely fitted with the arc-shaped surface of the outer surface of the second extension portion, so that the second extension portion can effectively press the first extension portion.

[0013] In a possible implementation of the first aspect, a dimension of the first extension portion projected on the support member in the Z-axis direction is a first dimension, a dimension of the second extension portion projected on the support member in the Z-axis direction is a second dimension, and the first dimension is greater than the second dimension. In this way, the second extension portion can effectively press the first extension portion.

[0014] In a possible implementation of the first aspect, the projection of the first extension portion on the second extension portion abuts against the projection of the rigid cover plate on the second extension portion. At this time, the rigid cover plate does not block the first extension portion of the flexible screen, and the rigid cover plate presses the flexible cover plate, and the flexible cover plate presses the flexible screen, thereby preventing the first extension portion of the flexible screen from arching or detaching from the support portion. The portion of the first extension portion of the flexible screen exposed to the outside through the flexible cover plate is a complete curved display screen, which improves the user experience.

[0015] In a possible implementation of the first aspect, the projection of the first extension on the second extension at least partially overlaps with the projection of the rigid cover on the second extension. When the second extension overlaps with the rigid cover, the pressing effect of the rigid cover can directly act on the flexible screen through the flexible cover, thereby enhancing the pressing effect of the rigid cover on the second extension of the flexible screen. At the same time, when the first extension of the flexible screen displays an arc through the flexible cover, the user cannot see the boundary of the flexible screen, which increases the aesthetics of the electronic device and improves the user experience.

[0016] In a possible implementation manner of the first aspect, a projection of the first extension portion on the second extension portion and a projection of the rigid cover plate on the second extension portion are spaced apart. In this case, the rigid cover plate does not block the first extension portion of the flexible screen, and the rigid cover plate presses the flexible cover plate, and the flexible cover plate presses the flexible screen, thereby preventing the first extension portion of the flexible screen from arching or detaching from the support portion.

[0017] In a possible implementation of the first aspect, the contact surface between the rigid cover plate and the support member is an arc-shaped surface, so that the contact area between the rigid cover plate and the support member is increased, and the connection between the rigid cover plate and the support member is stable.

[0018] In a possible implementation manner of the first aspect, at least a portion of the inner surface of the rigid cover plate is an arc-shaped surface, the edge of the support member further has a third side surface that is an arc-shaped surface, the arc-shaped surface of at least a portion of the third side surface matches the arc-shaped surface of at least a portion of the inner surface of the rigid cover plate, and the rigid cover plate covers at least a portion of the third side surface;

[0019] The outer surface of the second extension portion is an arc-shaped surface, and the arc-shaped surface of at least part of the outer surface of the second extension portion matches the arc-shaped surface of at least part of the inner surface of the rigid cover plate, and the rigid cover plate covers at least part of the second extension portion.

[0020] In a possible implementation manner of the first aspect, the rigid cover plate is relatively fixed to the second extension portion and the third side surface.

[0021] In a possible implementation manner of the first aspect, the support member further has a first step surface, and the first step surface connects the first side surface and the second side surface.

[0022] In a possible implementation of the first aspect, the width of the first step surface matches the thickness of the first extension portion. Thus, when the first extension portion covers the first side surface, the outer surface of the first extension portion is smoothly connected to the second side surface.

[0023] In a possible implementation manner of the first aspect, the first step surface matches an end surface of the first extending portion.

[0024] In a possible implementation manner of the first aspect, the support member further has a second step surface, and the second step surface connects the second side surface and the third side surface.

[0025] In a possible implementation of the first aspect, the width of the second step surface matches the thickness of the second extension portion, that is, when the second extension portion covers the second side surface, the outer surface of the second extension portion and the third side surface are located on the same circumference, so that the second extension portion and the third side surface have good consistency.

[0026] In a possible implementation manner of the first aspect, the second step surface matches an end surface of the second extending portion.

[0027] In a possible implementation manner of the first aspect, an angle between the second step surface and the first step surface is greater than 0 degree.

[0028] In a possible implementation of the first aspect, the support member has a first step surface, at least part of the first step surface matches the end surface of the first extension, at least part of the first step surface matches the end surface of the second extension, and the width of the first step surface is equal to the sum of the thickness of the first extension and the thickness of the second extension. In this way, when the first extension covers the first side surface, the end surface of the first extension abuts against at least part of the first step surface, and when the second extension covers the first extension, the end surface of the second extension abuts against at least part of the first step surface, the outer surface of the second extension and the third side surface are located on the same circumference, and the outer surface of the second extension is smoothly connected to the third side surface, so that the second extension and the third side surface have good consistency.

[0029] In a possible implementation of the first aspect, a first clamping portion is provided on the inner surface of the rigid cover plate, a second clamping portion matching the first clamping portion is provided on the support member, and the first clamping portion is matched and connected with the second clamping portion. In this way, the fixing reliability of the rigid cover plate can be enhanced, and the rigid cover plate can effectively press the flexible cover plate.

[0030] In a possible implementation manner of the first aspect, the second extending portion and / or the first extending portion has an avoidance groove, and the avoidance groove is used to avoid the first clamping portion or the second clamping portion.

[0031] In a possible implementation of the first aspect, the rigid cover plate is connected to the support member through a fastener, the rigid cover plate is provided with a first connecting hole, and the support member is provided with a second connecting hole. When the rigid cover plate covers at least a portion of the support member, the second connecting hole is opposite to the first connecting hole, and the fastener passes through the first connecting hole and the second connecting hole in sequence to connect the rigid cover plate and the support member.

[0032] In a possible implementation of the first aspect, the rigid cover plate includes at least a first section cover plate and a second section cover plate, the first section cover plate covers at least a portion of the second extension, the second section cover plate covers at least a portion of the support member, and the thickness of the first section cover plate is less than the thickness of the second section cover plate. The thickness of the rigid cover plate gradually becomes thinner until the rigid cover plate transitions to the curved surface of the flexible cover plate at the end portion facing the flexible cover plate, and on the basis of ensuring that the first extension portion of the flexible screen exposed to the outside through the flexible cover plate is a curved screen, the smoothness of the appearance of the electronic device and the good grip feel of the electronic device can be ensured.

[0033] In a second aspect, an embodiment of the present application provides an electronic device, comprising the above-mentioned display component.

[0034] The embodiments of the present application provide a display assembly and an electronic device, wherein the display assembly presses the first extension portion through the second extension portion, the rigid cover plate covers at least a portion of the edge of the support member, the rigid cover plate covers at least a portion of the second extension portion, and the rigid cover plate presses the second extension portion. In this way, when the electronic device is in a folded or bent state, the reverse elastic force generated by the first extension portion of the flexible screen will be offset by the rigid cover plate through the second extension portion, thereby preventing the screen assembly from being detached from the support portion due to the tension of the flexible screen. When the first extension portion of the flexible screen is attached to the first side surface in a bent state, the first extension portion of the flexible screen is protected to prevent the flexible screen from arching due to bending or folding. The first extension portion can perform an arc display, thereby increasing the screen-to-body ratio. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] An embodiment of the present application provides a display component, which includes at least a flexible screen. The display component may be a part of an electronic device, and the electronic device may be displayed through the flexible screen. The flexible screen has a bendable and flexible characteristic. Thus, the electronic device may have one or more usage states, and the usage state may be a folded state, an unfolded state, a bent state, and the like. For example, the electronic device has an unfolded state, or the electronic device has a bent state, or the electronic device has a bent state and an unfolded state, or the electronic device has a folded state and an unfolded state. Among them, when the electronic device is in a folded state, the electronic device has a smaller size, and the flexible screen is in a folded state. When the electronic device is in an unfolded state, the flexible screen is in a flat unfolded state. When the electronic device is in a bent state, the flexible screen is in a bent state.

[0065] The electronic device may be a smart phone, a laptop, a tablet computer, a smart watch, an e-book, a virtual reality (VR) device, an augmented reality (AR) device, a mixed reality (MR) device, etc. The electronic device supports the installation of various types of desktop applications, and the flexible screen can display various desktop applications in full screen or split screen. Desktop applications include but are not limited to photo applications, browser applications, instant messaging applications, game applications, video player applications, office automation applications, etc.

[0066] A flexible cover plate can be provided on the flexible screen, which can realize the folding, unfolding, bending and other states of the electronic device. If a flexible cover plate is used, the side edge of the flexible screen will generate reverse elastic force during the bending process, and the side edge of the flexible screen and the arc-shaped support part cannot be effectively bonded, resulting in the separation of the flexible screen and the support part. Therefore, it is necessary to improve the installation and fixing method of the flexible screen to achieve effective fixation of the flexible screen and the arc-shaped support part, increase the screen-to-body ratio, and improve the grip feel of the electronic device. In order to achieve the above technical effects, the embodiment of the present application adds a rigid cover plate on the basis of the flexible cover plate, and the side edge of the flexible screen is fixed by the rigid cover plate to avoid the separation of the flexible screen and the support part.

[0067] The display component provided in the present application is described in detail using specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar contents will not be repeated in different embodiments.

[0068] For the convenience of description, in the following embodiments, the electronic device is taken as a smart phone, and the display component is applied to the smart phone and described in detail as a part of the smart phone. The implementation method of applying the display component to other devices is similar and will not be repeated in this embodiment.

[0069] The implementation of the display component provided in the present application is described in detail below in conjunction with the embodiments.

[0070] Figure 1 A schematic diagram of the structure of a display assembly provided in an embodiment of the present application, Figure 2 An exploded schematic diagram of a display assembly provided in one embodiment of the present application; Figure 3 A schematic diagram of the structure of a first screen assembly in a display assembly provided in an embodiment of the present application; Figure 4 A front view of a display assembly provided in one embodiment of the present application; Figure 5 for Figure 4 It should be noted that the drawings of the embodiments of the present application are only exemplary, and the display assembly of the present application is not limited to application in electronic devices. Figures 1 to 5 As shown, the display assembly provided in this embodiment includes: a screen assembly 50 , a rigid cover plate 40 and a support member 10 , the screen assembly 50 is located on the support member 10 , and the rigid cover plate 40 connects the screen assembly 50 and the support member 10 .

[0071] See also Figure 3As shown, the screen assembly 50 can provide a flat display area 51 and a curved display area 52. The flat display area 51 is the main display area of ​​the electronic device, and the curved display area 52 is located at the edge of the flat display area 51, which can provide a curved display, which can also be understood as a curved display. The curved display area 52 increases the display area of ​​the electronic device, so that the electronic device can also display a curved surface on the basis of a flat display, thereby increasing the screen-to-body ratio. Among them, the screen-to-body ratio refers to the relative ratio of the screen and the front panel area of ​​the mobile phone projected in the front direction.

[0072] See also Figure 2 and Figure 5 As shown, the screen assembly 50 includes a flexible screen 20 and a flexible cover plate 30 covering the flexible screen 20. The flexible screen 20 may be, for example, a flexible organic light-emitting diode (OLED) screen. At least part of the edge of the flexible screen 20 has a first extension portion 21 extending outward from the flexible screen 20. The first extension portion 21 is in an arc shape. The first extension portion 21 also has the same display function as the flexible screen 20. The first extension portion 21 can provide an arc display, that is, the flexible screen 20 should be in the above Figure 3 The plane display area 51 in the first extension portion 21 corresponds to the above Figure 3 The curved display area 52 in the embodiment of the present invention.

[0073] The number and position of the first extension portion 21 of the flexible screen 20 can be determined according to the display requirements of the electronic device. For example, when one side of the electronic device is a curved display, the flexible screen 20 has a first extension portion 21. Figure 1 As shown, or when the two opposite curved surfaces of the electronic device are displayed, there is a first extension portion 21 on the edges of the two opposite sides of the support member 10. This embodiment does not specifically limit the number and position of the first extension portions 21 of the flexible screen 20.

[0074] The flexible cover plate 30 covers the flexible screen 20 . The flexible cover plate 30 is a flexible, bendable and transparent cover plate. The flexible cover plate 30 may be made of a material with high surface hardness and high light transmittance, such as polyethylene terephthalate, polyimide, etc.

[0075] The flexible cover 30 has multiple functions. For example, it can protect the flexible screen 20 and prevent the flexible screen 20 from being damaged by external forces. At the same time, it can bend with the flexible screen 20 so that the electronic device can be in different states such as folding and bending.

[0076] When the flexible cover plate 30 covers the flexible screen 20, the flexible cover plate 30 is connected to the flexible screen 20 to fix the flexible cover plate 30 on the flexible screen 20 so that the flexible cover plate 30 can be bent together with the flexible screen 20. For example, the lower surface of the flexible cover plate 30 covers the upper surface of the flexible screen 20, and the lower surface of the flexible cover plate 30 can be adhered to the upper surface of the flexible screen 20 by gluing. This embodiment does not impose any special restrictions on the bonding method of the flexible cover plate 30 and the flexible screen 20.

[0077] Since at least part of the edge of the flexible screen 20 has a first extension portion 21 extending outward, in order to enable the flexible cover plate 30 to fix the first extension portion 21 of the flexible screen 20, at least part of the edge of the flexible cover plate 30 has a second extension portion 31 extending outward, the second extension portion 31 is in an arc shape, the second extension portion 31 covers the first extension portion 21, and the first extension portion 21 is fixed by the second extension portion 31. Optionally, the lower surface of the second extension portion 31 covers the upper surface of the first extension portion 21, and the lower surface of the second extension portion 31 can be adhered to the upper surface of the first extension portion 21 by gluing. This embodiment does not particularly limit the bonding method of the second extension portion 31 and the first extension portion 21.

[0078] The number and position of the second extension portions 31 may be determined accordingly according to the number and position of the first extension portions 21 . The determination of the number and position of the first extension portions 21 has been described above and will not be repeated here.

[0079] See also Figure 2 , Figure 3 and Figure 5 As shown, the support member 10 may be a frame constituting the electronic device, and the screen assembly 50 and the back cover of the electronic device may be connected to two opposite sides of the support member 10, respectively. The support member 10 may also be a middle frame, a frame body, etc. The edge of the support member 10 is at least partially a connecting edge 11 in the shape of an arc surface, and the connecting edge 11 includes a first side surface 111, and the first side surface 111 is a part of the connecting edge 11, so the first side surface 111 is also in the shape of an arc surface, wherein the position of the first side surface 111 corresponds to the position of the first extension portion 21, the inner surface of the first extension portion 21 matches the arc surface of the first side surface 111, and the first extension portion 21 covers the first side surface 111, so that the support member 10 supports the flexible screen 20.

[0080] See also Figure 2 and Figure 5 As shown, the rigid cover plate 40 is used to fix the flexible cover plate 30. The rigid cover plate 40 covers at least part of the edge of the support member 10, and the rigid cover plate 40 also covers at least part of the second extension portion 31, so that the flexible cover plate 30 is connected to the support member 10 through the rigid cover plate 40.

[0081] The rigid cover plate 40 can be used as a part of the appearance of the electronic device and directly exposed to the outside, or a shell can be covered on the outside of the rigid cover plate 40 to hide the rigid cover plate 40, so as to make the appearance of the electronic device more beautiful.

[0082] The rigid cover plate 40 can be made of one of the materials selected from plastic, ceramic, glass or metal, or a composite of at least two of them. The material used for the rigid cover plate 40 is not particularly limited in this embodiment.

[0083] The rigid cover plate 40 may be a transparent cover plate or an opaque cover plate, which may be determined according to the requirements of the electronic device and the selected material.

[0084] The display assembly provided in this embodiment covers the first extension part 21 through the second extension part 31, that is, the second extension part 31 can press the first extension part 21, and the rigid cover plate 40 covers at least part of the edge of the support member 10, and the rigid cover plate 40 covers at least part of the second extension part 31, that is, the rigid cover plate 40 is connected to the support member 10, and the rigid cover plate 40 can press the second extension part 31. In this way, when the electronic device is in a folded or bent state, the reverse elastic force generated by the first extension part 21 of the flexible screen 20 will be offset by the rigid cover plate 40 through the second extension part 31, preventing the screen assembly 50 from being detached from the support part due to the tension of the flexible screen 20. When the first extension part 21 of the flexible screen 20 is attached to the first side surface 111 in a bent state, the first extension part 21 of the flexible screen 20 is protected to prevent the flexible screen 20 from being arched due to bending or folding.

[0085] Please continue to see Figure 5 As shown, in this embodiment, since the connecting edge 11 is an arc-shaped edge, the first extension portion 21 of the flexible screen 20 is in a bent state to cover the first side surface 111 of the connecting edge 11 .

[0086] In order to enable the second extending portion 31 to effectively press the first extending portion 21 , the first extending portion 21 and the second extending portion 31 may have the following positional arrangements.

[0087] See also Figure 5As shown, the connecting edge 11 also includes a second side surface 112, and the second side surface 112 can be a plane or an arc-shaped surface. The arc-shaped surface of the second side surface 112 matches at least a part of the arc-shaped surface of the inner surface of the second extension portion 31, that is, the distance that the second extension portion 31 extends to the outside of the flexible cover plate 30 is greater than the distance that the first extension portion 21 extends to the outside of the flexible screen 20. The first extension portion 21 covers the first side surface 111 of the connecting edge 11, and the second extension portion 31 covers the second side surface 112 of the connecting edge 11. The second extension portion 31 covers the first extension portion 21. The dimension of the second extension portion 31 projected on the support member 10 in the Z-axis direction is a first dimension, and the dimension of the first extension portion 21 projected on the support member 10 in the Z-axis direction is a second dimension. The first dimension is greater than the second dimension, and the Z-axis direction is a direction perpendicular to the plane of the flexible cover plate 30. The position of the connecting edge 11 covered by the first extension portion 21 is different from the position of the connecting edge 11 covered by the second extension portion 31.

[0088] Optionally, the difference between the first size and the second size may be between 2-5 mm. In this way, while the second extension portion 31 can effectively press the first extension portion 21, the material of the flexible screen 20 can also be saved, thereby reducing costs.

[0089] Figure 6 for Figure 4 The second AA profile in . Figure 6 As shown, the extension distance of the second extension portion 31 is equal to the extension distance of the first extension portion 21, that is, only the first extension portion 21 covers the first side surface 111 of the connecting edge 11, and the second extension portion 31 covers the first extension portion 21. In this way, the second extension portion 31 can cover the first extension portion 21, and the second extension portion 31 presses the first extension portion 21.

Figure 5 and Figure 7As shown, in this embodiment, at least part of the inner surface of the rigid cover plate 40 is an arc-shaped surface, and the connecting edge 11 further includes a third side surface 113, and the third side surface 113 is an arc-shaped surface. A part of the inner surface of the rigid cover plate 40 matches the third side surface 113 of the connecting edge 11, and another part of the inner surface of the rigid cover plate 40 matches the outer surface of the second extension 31. In this way, it is convenient to process the support member 10 and the rigid cover plate 40, and when the third side surface 113 of the connecting edge 11 and the second extension 31 are connected to the rigid cover plate 40, a part of the inner surface of the rigid cover plate 40 overlaps with the third side surface 113 of the connecting edge 11, and another part of the inner surface of the rigid cover plate 40 overlaps with the outer surface of the second extension 31, thereby increasing the contact area between the third side surface 113 and the rigid cover plate 40, and the contact area between the second extension 31 and the rigid cover plate 40, so that the rigid cover plate 40 can be more stably connected to the third side surface 113 and the second extension 31.

[0091] See also Figure 7 As shown, the inner surface of the first extension part 21 of the flexible screen 20 and the outer surface of the first extension part 21 of the flexible screen 20 are arc-shaped surfaces; the inner surface of the second extension part 31 of the flexible cover plate 30 is an arc-shaped surface; the matching area between the second extension part 31 and the rigid cover plate 40 can be a plane or an arc-shaped surface; the matching area between the rigid cover plate 40 and the support part 10 can be a plane or an arc-shaped surface. In order to facilitate the understanding of the scheme, the drawings of this embodiment are all illustrated with arc-shaped surfaces.

[0092] Please continue to see Figure 5 and Figure 7 As shown, in this embodiment, the support member 10 further has a first step 13, the first step 13 has a first step side wall 131 and a first step surface 132, the first step surface 132 of the first step 13 connects the first side surface 111 and the second side surface 112, and the first step side wall 131 is the first side surface 111. The first step side wall 131 of the first step 13 is an arc shape matching the inner surface of the first extension portion 21, so that the contact area between the first extension portion 21 and the first side surface 111 is increased, so that the first extension portion 21 and the first side surface 111 can be more firmly connected.

[0093] The width of the first step surface 132 of the first step 13 matches the thickness of the first extension portion 21. When the first extension portion 21 covers the first side surface 111, the outer surface of the first extension portion 21 and the second side surface 112 are located on the same circumference, and the outer surface of the first extension portion 21 is smoothly connected to the second side surface 112. Optionally, when the first extension portion 21 covers the first side surface 111, the first step surface 132 of the first step 13 abuts against the end surface of the first extension portion 21, and the first step surface 132 of the first step 13 matches the end surface of the first extension portion 21.

The second step side wall 121 of the second step 12 is an arc shape that matches the inner surface of the second extension portion 31, so that the second extension portion 31 covers the second step side wall 121, and the second step side wall 121 overlaps with the inner surface of the second extension portion 31, thereby increasing the contact area between the second extension portion 31 and the second side surface 112, so that the second extension portion 31 and the second side surface 112 can be more firmly connected.

[0095] The width of the second step surface 122 of the second step 12 matches the thickness of the second extension portion 31. That is, when the second extension portion 31 covers the second side surface 112, the outer surface of the second extension portion 31 and the third side surface 113 are located on the same circumference, and the outer surface of the second extension portion 31 is smoothly connected to the third side surface 113, so that the second extension portion 31 and the third side surface 113 have good consistency. Accordingly, the inner surface of the rigid cover plate 40 matching the outer surface of the second extension portion 31 is a continuous arc surface, which is convenient for processing the rigid cover plate 40.

[0096] Optionally, when the second extension portion 31 covers the second side surface 112, the second step surface 122 of the second step 12 abuts against the end surface of the second extension portion 31, and the second step surface 122 of the second step 12 matches the end surface of the second extension portion 31.

The angle between the first step surface 132 and the second step surface 122 is greater than 0°. The angle between the first step surface 132 and the second step surface 122 is determined according to the end surface of the second extension portion 31 and the end surface of the first extension portion 21, and this embodiment is not limited here.

[0098] Above Figure 5 and Figure 7 In the illustrated embodiment, two steps, namely the second step 12 and the first step 13 , are provided on the connecting edge 11 of the support member 10 . Alternatively, one step may be provided on the connecting edge 11 of the support member 10 .

[0099] Figure 8 for Figure 6 Schematic diagram of the partial structure of the middle support. Figure 6 and Figure 8 As shown, in this embodiment, the support member 10 further has a first step 13, the first step 13 has a first step side wall 131 and a first step surface 132, the first step surface 132 connects the first side surface 111 and the third side surface 113, the first step side wall 131 is an arc shape matching the inner surface of the first extension portion 21, and the width of the first step surface 132 is equal to the sum of the thickness of the first extension portion 21 and the thickness of the second extension portion 31. When the first extension portion 21 covers the first side surface 111, the end surface of the first extension portion 21 abuts against at least part of the first step surface 132, and when the second extension portion 31 covers the first extension portion 21, the end surface of the second extension portion 31 abuts against at least part of the first step surface 132, the outer surface of the second extension portion 31 and the third side surface 113 are located on the same circumference, and the outer surface of the second extension portion 31 is smoothly connected to the third side surface 113, so that the second extension portion 31 and the third side surface 113 have good consistency.

[0100] Optionally, the end surface of the first extension portion 21 matches a portion of at least a portion of the first step surface 132, and the end surface of the second extension portion 31 matches another portion of at least a portion of the first step surface 132. At least a portion of the first step surface 132 may be a plane, at least a portion of the first step surface 132 may be a curved surface, or at least a portion of the first step surface 132 may be an irregular surface, which is not limited in this embodiment.

[0101] Please continue to see Figure 5As shown, the rigid cover plate 40 can be a transparent cover plate or an opaque cover plate. For example, when the rigid cover plate 40 is an opaque cover plate, the rigid cover plate 40 covers part of the second extension portion 31, thereby ensuring that the first extension portion 21 of the flexible screen 20 can be displayed in an arc through the second extension portion 31 not covered by the rigid cover plate 40, and when the rigid cover plate 40 is a transparent cover plate, the rigid cover plate 40 can cover at least part of the second extension portion 31, both of which can ensure that the first extension portion 21 of the flexible screen 20 can be displayed in an arc.

[0102] Optionally, when the rigid cover plate 40 covers part of the second extension portion 31 , the positions of the first extension portion 21 of the flexible screen 20 and the rigid cover plate 40 also have multiple implementation methods, which are described in detail with reference to the drawings.

[0103] Fig. 9 for Figure 5 The first partial enlarged view of B in the figure. Fig. 9 As shown, the projection of the end of the first extension 21 on the second extension 31 abuts against the projection of the end of the rigid cover plate 40 on the second extension 31. In this implementation, the rigid cover plate 40 does not block the first extension 21 of the flexible screen 20. The rigid cover plate 40 presses the flexible cover plate 30, and the flexible cover plate 30 presses the flexible screen 20, thereby preventing the first extension 21 of the flexible screen 20 from arching or detaching from the support portion. At this time, the portion of the first extension 21 of the flexible screen 20 exposed to the outside through the flexible cover plate 30 is a complete curved display screen, which improves the user experience.

[0104] Fig.10 for Figure 5 The second partial enlarged view of B in the figure. Fig.10 As shown, there is a distance between the projection of the end of the first extension portion 21 on the second extension portion 31 and the projection of the end of the rigid cover plate 40 on the second extension portion 31. Optionally, the distance may be between 0 and 2 mm. Fig. 9 The same principle as in the embodiment, the rigid cover plate 40 does not block the first extension portion 21 of the flexible screen 20, and the rigid cover plate 40 presses the flexible cover plate 30, and the flexible cover plate 30 presses the flexible screen 20, thereby preventing the first extension portion 21 of the flexible screen 20 from arching or detaching from the support portion. At this time, when the first extension portion 21 of the flexible screen 20 is displayed through the flexible cover plate 30 for curved display, the user can see the boundary of the flexible screen 20.

[0105] Optionally, an opaque frame is provided at the position corresponding to the above-mentioned spacing on the flexible cover plate 30 to block the boundary of the flexible screen 20 , so that the user cannot see the boundary of the flexible screen 20 , thereby ensuring the aesthetic appearance of the electronic device and improving the user experience.

[0106] Fig.11 for Figure 5 The third partial enlarged view of B in the middle. Fig.11 As shown, the area of ​​the projection of the first extension 21 on the second extension 31 is smaller than the area of ​​the projection of the rigid cover plate 40 on the second extension 31, that is, the projection of the first extension 21 on the second extension 31 partially overlaps with the projection of the rigid cover plate 40 on the second extension 31. Optionally, the length of the overlapping area can be between 1-3 mm, that is, the distance between the edge of the projection of the first extension 21 on the second extension 31 and the edge of the projection of the rigid cover plate 40 on the second extension 31 is between 1-3 mm. When the second extension 31 and the rigid cover plate 40 have an overlapping portion, the pressing effect of the rigid cover plate 40 can directly act on the flexible screen 20 through the flexible cover plate 30, thereby enhancing the pressing effect of the rigid cover plate 40 on the second extension 31 of the flexible screen 20. At the same time, when the first extension 21 of the flexible screen 20 is displayed through the flexible cover plate 30 for curved display, the user cannot see the boundary of the flexible screen 20, which increases the aesthetics of the electronic device and improves the user experience.

[0107] Fig.12 for Figure 6 A partial enlarged view of point E in the middle. Fig.12 As shown, the area of ​​the projection of the first extension 21 on the second extension 31 is equal to the area of ​​the projection of the rigid cover plate 40 on the second extension 31, that is, the projection of the first extension 21 on the second extension 31 overlaps with the projection of the rigid cover plate 40 on the second extension 31. When the second extension 31 overlaps with the rigid cover plate 40, the pressing effect of the rigid cover plate 40 can directly act on the flexible screen 20 through the flexible cover plate 30, thereby enhancing the pressing effect of the rigid cover plate 40 on the second extension 31 of the flexible screen 20. Please continue to refer to Figure 5 As shown, the assembly process of the display assembly provided in the above embodiment is described below. The assembly process of the display assembly mainly includes three steps: step 1, the flexible cover plate 30 and the flexible screen 20 are bonded to obtain the screen assembly 50; step 2, the screen assembly 50 is fixed to the support member 10; step 3, the rigid cover plate 40 is fixed to the support member 10. The above three steps are described in detail below.

[0108] Step 1: The flexible cover plate 30 and the flexible screen 20 are bonded together to obtain a screen assembly 50.

[0109] Please continue to see Figure 5 As shown, the flexible cover plate 30 and the flexible screen 20 can be bonded together, and the second extension portion 31 covers the first extension portion 21, so as to obtain an integrated screen assembly 50. That is, the inner surface of the flexible cover plate 30 and the outer surface of the flexible screen 20 are bonded together, and the inner surface of the second extension portion 31 covers the outer surface of the first extension portion 21.

[0110] The flexible cover plate 30 and the flexible screen 20 can be glued together by roller type, vacuum type or other bonding methods, and the adhesive used can be, for example, an optically clear adhesive (OCA). The OAC has the characteristics of being colorless and transparent, and can ensure that the flexible screen 20 can be displayed through the flexible cover plate 30, and the display effect is guaranteed.

[0111] Step 2: Fixing the screen assembly 50 and the support member 10.

[0112] The first extension part 21, or part of the first extension part 21 and part of the second extension part 31 in the screen assembly 50 can be respectively bonded to the first side surface 111 and the second side surface 112 of the support member 10 by dispensing glue or back glue. During the installation process, for example, the positioning can be completed by a positioning method based on a charge-coupled device (CCD), that is, to ensure that the screen assembly 50 is installed on the support member 10. This embodiment does not specifically limit the positioning method of the screen assembly 50 and the support member 10.

[0113] Step 3: Fixing the rigid cover plate 40 to the support member 10 .

[0114] The rigid cover plate 40 can be fixed to the support member 10 in a variety of ways, such as bonding, snap fastening, bolts, etc., which will be described in detail below with reference to the drawings.

[0115] Fig.13 for Figure 5 The fourth partial enlarged view of B in the middle. Fig.13 As shown, the rigid cover plate 40 is bonded to the support member 10 by gluing. For example, it can be bonded by dispensing glue or back glue. When the rigid cover plate 40 is fixed by gluing, the rigid cover plate 40 is not only bonded to the support member 10, but also bonded to the flexible cover plate 30, forming a bond as shown in FIG. Fig.13 Adhesive layer 60 is shown.

[0116] When the rigid cover plate 40 and the support member 10 are fixed by gluing, the material of the rigid cover plate 40 may be metal material, plastic material, glass material or ceramic material, etc. The strength of the adhesive or adhesive can be increased by increasing the surface roughness of the inner surface of the rigid cover plate 40 and selecting adhesive or adhesive material with strong viscosity. The inner surface of the rigid cover plate 40 may be sandblasted or roughened to increase the surface roughness of the inner surface of the rigid cover plate 40.

[0117] In some implementations, the rigid cover plate 40 and the support member 10 may also be fixed by physical mechanical connection. For example, a first connection portion is provided on the rigid cover plate 40, and a second connection portion matching the first connection portion is provided on the support member 10, and the rigid cover plate 40 and the support member 10 are fixed by matching and connecting the first connection portion and the second connection portion. The physical mechanical connection may be a fixed connection or a detachable connection, and the present embodiment does not impose any particular restrictions on the implementation of the connection.

[0118] In order to ensure that the rigid cover plate 40 is subjected to uniform force and to ensure the fixing effect of the rigid cover plate 40 , two or more first connecting parts may be evenly arranged in the extension direction of the rigid cover plate 40 , and correspondingly, two or more second connecting parts may be evenly arranged at relative positions on the support member 10 .

[0119] In the specific implementation process, the first connecting part and the second connecting part can be connected by gluing, or by a physical mechanical connection, or by adding a physical mechanical connection on the basis of gluing. By adding the physical mechanical connection, the fixing reliability of the rigid cover plate 40 can be enhanced, and the rigid cover plate 40 can ensure an effective pressing effect on the flexible cover plate 30.

[0120] Fig.14 for Figure 4 The third cross-section of the middle AA; Fig.15 for Fig.14 A partial enlarged view of point C in the middle; Fig.16 An exploded view of a second screen assembly in a display assembly provided in an embodiment of the present application; Fig.17 This is an exploded view of the third screen assembly in the display assembly provided in one embodiment of the present application. Figures 14 to 17 As shown, the rigid cover plate 40 can be fixed to the support member 10 by snapping. Specifically, the first connection structure can be a first snap-fitting portion 41 provided on the inner surface of the rigid cover plate 40, and the second connection structure can be a second snap-fitting portion 15 provided on the support member 10, and the first snap-fitting portion 41 snaps with the second snap-fitting portion 15, so that the rigid cover plate 40 and the support member 10 are fixed by snapping.

[0121] The first engaging portion 41 can be a structure for engaging that protrudes from the inner surface of the rigid cover plate 40, such as a hook, a card, a column, a buckle, etc. The second engaging portion 15 is a structure for engaging with the first engaging portion 41, such as a slot, a snap ring, a lock, etc.

[0122] Fig.14 and Fig.15In the schematic structure shown, the first engaging portion 41 is a hook, and the second engaging portion 15 is a slot, and the hook engages with the slot. The slot has a guide slope 151, which is inclined toward the inside of the slot. When the hook is pushed into the slot, the guide slope 151 provides guidance for the hook, so that the hook can be easily inserted into the slot. The end of the hook away from the rigid cover plate 40 is provided with a chamfer 411, which has a guiding function, so that the hook can be easily inserted into the slot.

[0123] See also Fig.16 As shown, when the second extension portion 31 of the flexible cover plate 30 blocks the second clamping portion 15 and the first extension portion 21 of the flexible screen 20 does not block the second clamping portion 15, an avoidance groove 16 is provided on the second extension portion 31 of the flexible cover plate 30 to prevent the second extension portion 31 of the flexible cover plate 30 from interfering with the second clamping portion 15 or the first clamping portion 41.

[0124] See also Fig.17 As shown, the screen assembly 50 includes a flexible screen 20 and a flexible cover plate 30 covering the flexible screen 20. When the second extension portion 31 of the flexible cover plate 30 and the first extension portion 21 of the flexible screen 20 both block the second clamping portion 15, avoidance grooves 16 are provided at relative positions of the second extension portion 31 of the flexible cover plate 30 and the first extension portion 21 of the flexible screen 20 to prevent the screen assembly 50 from interfering with the second clamping portion 15 or the first clamping portion 41.

[0125] When the rigid cover plate 40 is provided with the first engaging portion 41, the rigid cover plate 40 can be made of plastic material, and the first engaging portion 41 and the rigid cover plate 40 are integrally injection molded to reduce costs. The rigid cover plate 40 can also be made of metal material, which has higher strength, a metallic luster on the surface, and better hand feel and appearance.

[0126] In this embodiment, a first snap-fitting portion 41 is provided on the rigid cover 40, and a second snap-fitting portion 15 matching the first snap-fitting portion 41 is provided on the support 10. The first snap-fitting portion 41 and the second snap-fitting portion 15 cooperate to fix the rigid cover 40 on the support 10. The rigid cover 40 presses the first extension portion 21 of the flexible screen 20 onto the connecting edge 11 of the support 10 through the second extension portion 31 of the flexible cover 30, thereby ensuring the flatness and fixing strength of the flexible screen 20 in the curved surface area. At the same time, the snap-fitting method is used for fixing, which is easy to disassemble and can be reused, making it convenient to repair electronic equipment.

[0127] Fig.18 for Figure 4 The fourth cross-section of the middle AA; Fig.19 for Fig.18 A partial enlarged view of point D in the middle. Fig.18 and Fig.19As shown, the rigid cover plate 40 can be connected to the support member 10 by screw connection.

[0128] Specifically, the first connection structure mentioned above can be a first connection hole 42 set on the rigid cover plate 40, and the second connection structure mentioned above can be a second connection hole 14 set on the support member 10. The first connection hole 42 and the second connection hole 14 are opposite to each other and are connected by screws.

[0129] Optionally, the first connecting hole 42 is a countersunk hole (also called a stepped hole), and the first connecting hole 42 is a cylindrical countersunk hole or a conical countersunk hole, and the head of the screw is sunk into the stepped hole of the part, thereby ensuring the aesthetic appearance of the electronic device.

[0130] The rigid cover plate 40 can be formed by plastic injection molding, or metal can be formed by CNC process. The CNC process is computer digital controlled precision machining, which is convenient for machining the first connection hole 42 and the second connection hole 14, and has high machining accuracy. In addition, the rigid cover plate 40 is made of brittle materials such as glass and ceramics, which are difficult to use in the clamping structure, and can also be used in the screw structure.

[0131] The rigid cover plate 40 is fixed to the support member 10 by screws, and the fixing strength is higher, and the rigid cover plate 40 is not easy to loosen and fall off. At the same time, the tightening force of the screws can also control the pressing force of the rigid cover plate 40 on the flexible screen 20 to ensure that the flexible screen 20 is pressed and flattened.

[0132] Please continue to see Fig.18 and Fig.19 As shown, the thickness of the rigid cover plate 40 can be gradually thinner, and the thickness of the end of the rigid cover plate 40 facing the flexible cover plate 30 is the thinnest. The end of the rigid cover plate 40 facing the flexible cover plate 30 transitions with the curved surface of the flexible cover plate 30. On the basis of ensuring that the first extension portion 21 of the flexible screen 20 is exposed to the outside through the flexible cover plate 30 as a curved screen, the smoothness of the appearance of the electronic device and the good grip feel of the electronic device can be ensured. Among them, the rigid cover plate 40 at least includes a first section cover plate 43 and a second section cover plate 44, the first section cover plate 43 covers at least a portion of the second extension portion 31, the second section cover plate 44 covers at least a portion of the support member 10, and the thickness of the first section cover plate 43 is less than the thickness of the second section cover plate 44.

[0133] Fig. 20 A schematic diagram of a structure of an electronic device in one state provided by an embodiment of the present application; Fig.21 This is a schematic diagram of another state of an electronic device provided by an embodiment of the present application. Fig. 20 and Fig.21 As shown, the electronic device includes the display component provided by the above embodiment.

[0134] The specific structure, function and working principle of the display component have been described in detail in the above embodiments and will not be repeated here.

[0135] The electronic device may be a smart phone, a laptop computer, a tablet computer, a smart watch, an e-book, a virtual reality (VR) device, an augmented reality (AR) device, or a mixed reality (MR) device, which will not be described in detail in this embodiment.

[0136] In addition, the electronic device may also include structures such as a circuit board and a power switch.

[0137] Please continue to see Fig. 20 and Fig.21 As shown, the display assembly includes a support 10, a screen assembly 50 disposed on the support 10, a rigid cover plate 40, and a hinge 70. The screen assembly 50 includes a flexible screen 20 and a flexible cover plate 30 covering the flexible screen 20, and the flexible screen 20 is located on the support 10.

[0138] Since the screen assembly 50 includes the flexible screen 20 and the flexible cover 30, and both the flexible screen 20 and the flexible cover 30 are flexible and bendable, the electronic device can be folded during the rotation of the shaft 70. Fig.21 As shown, under the action of the rotating shaft 70, the electronic device is in a folded state. At this time, the middle part of the screen assembly 50 is in a bent state, and the size of the electronic device becomes smaller, making it easier for users to carry.

[0139] It should be noted that Fig. 20 and Fig.21 This is only an example, and the electronic device of the present application is not limited to a foldable electronic device.

[0140] The present embodiment does not impose any particular limitation on the structure of the rotating shaft 70 , as long as the rotating shaft 70 can enable the electronic device to be folded.

[0141] Please continue to see Figure 3 , Figure 5 and Fig. 20As shown, in this embodiment, the second extension portion 31 covers the first extension portion 21, that is, the second extension portion 31 can press the first extension portion 21, the rigid cover plate 40 covers the first side surface 111 of the support member 10, and the rigid cover plate 40 covers at least part of the second extension portion 31, that is, the rigid cover plate is connected to the support member 10, and the rigid cover plate 40 can press the second extension portion 31. In this way, when the electronic device is in a folded or bent state, the reverse elastic force generated by the first extension portion 21 of the flexible screen 20 will be offset by the rigid cover plate 40 through the second extension portion 31, preventing the screen assembly 50 from being detached from the support portion due to the tension of the flexible screen 20. When the first extension portion 21 of the flexible screen 20 is attached to the curved connection edge 11, the first extension portion 21 of the flexible screen 20 is protected to prevent the flexible screen 20 from being arched due to bending or folding.
