[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0049] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0050] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0051] In order to obtain a larger screen-to-body ratio and provide customers with a good visual experience, narrowing the border has become a trend in display devices, but narrow borders also bring the risk of low reliability. Figure 1 As shown, the filling part 4 is directly bonded to the middle frame 1, which reduces the frame of the display panel 21. However, the bonding method easily causes the filling part 4 to peel off from the middle frame 1, and the middle frame 1 still occupies the frame of the display device, resulting in the frame of the display device being still relatively wide. Therefore, the display device has the problem of a wide frame and low reliability.

[0052] Based on this, the present disclosure provides a display device. Figures 1 to 15As shown, the display device includes a middle frame 1, a display module 2, a cover plate 3 and a filling portion 4, the middle frame 1 has an installation notch 11, and the installation notch 11 includes a supporting surface 111 and a blocking surface 112 connected to each other; the display module 2 is arranged in the installation notch 11, the side of the display module 2 is opposite to the blocking surface 112, and the non-display surface of the display module 2 is opposite to the supporting surface 111; the cover plate 3 is arranged on the display surface of the display panel 21, the edge of the cover plate 3 is flush with the edge of the middle frame 1, and the edge of the orthographic projection of the display module 2 on the cover plate 3 is retracted relative to the edge of the cover plate 3; the filling portion 4 is arranged in an area surrounded by the supporting surface 111, the blocking surface 112, the cover plate 3, the non-display area of ​​the display surface of the display module 2, the side of the display module 2, and the non-display surface of the display module 2; the middle frame 1 is provided with a first clamping portion, and the filling portion 4 is provided with a second clamping portion, and the second clamping portion is clamped together with the first clamping portion.

[0053] The filling portion 4 is arranged in an area surrounded by the supporting surface 111 of the middle frame 1, the blocking surface 112 of the middle frame 1, the cover plate 3, the non-display area of ​​the display surface of the display module 2, the side of the display module 2, and the non-display surface of the display module 2. The middle frame 1 is provided with a first clamping portion, and the filling portion 4 is provided with a second clamping portion. The second clamping portion is clamped together with the first clamping portion, thereby realizing the assembly of the display device, with high fixing strength and higher assembly accuracy than adhesive bonding. At the same time, it also realizes that the edge of the cover plate 3 is flush with the edge of the middle frame 1, eliminating the increase in the frame caused by the middle frame 1 and significantly reducing the frame of the display device.

[0054] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig. 9 As shown, the embodiment of the present disclosure provides a display component, which may include a display module. The display module 2 includes a display panel 21, and the display panel 21 includes a display portion 211 and a non-display portion 212. The display portion 211 is provided in the display area of ​​the display panel 21, and the non-display portion 212 is provided in the non-display area of ​​the display panel 21. The non-display portion 212 includes a bending portion 2121 and a binding portion 2122. The bending portion 2121 is connected to the display portion 211, and the binding portion 2122 is adjacent to the side of the bending portion 2121 away from the display portion 211, and is attached to the non-display side of the display panel 21 through the bending portion 2121. The display portion 211 can perform the display function of the display module 2, and the display portion 211 has a display device. The binding portion 2122 is provided with a circuit board, and the circuit board is connected with metal traces. The metal traces extend to the display portion 211 through the bending portion 2121, and are connected to the display device to achieve the binding of the binding portion 2122.

[0055] A support layer group 22 is provided between the display portion 211 and the binding portion 2122 of the display panel 21. In order to closely fit the display panel 21 and the support layer group 22 and obtain a good display effect, one end of the display panel 21 after profiling is bonded to the front side of the support layer group 22, and is bent along the side of the support layer group to the back side of the support layer group 22, and the other end of the display panel 21 is bonded to the back side of the support layer group 22. The display portion 211 and the end of the bending portion 2121 connected to the display portion 211 are bonded to the front side of the support layer group 22, and the binding portion 2122 and the end of the bending portion 2121 connected to the binding portion 2122 are bonded to the back side of the support layer group 22.

[0056] The support layer group 22 includes a first back film 221, a heat dissipation film 222, an adhesive layer 223, and a second back film 224 arranged in sequence. The heat dissipation film 222 is arranged on one side of the first back film 221, the adhesive layer 223 is arranged on the side of the heat dissipation film 222 away from the first back film 221, and the second back film 224 is arranged on the side of the adhesive layer 223 away from the first back film 221. The non-display portion 212 is connected to the first back film 221 on the display side of the display panel 21, and the non-display portion 212 is connected to the second back film 224 on the non-display side of the display panel 21. A protective glue 23 is provided on the side of the non-display portion 212 away from the support layer group 22, which can buffer part of the bending stress during the bending process of the display panel 21, and form protection for the bending portion 2121 of the non-display portion 212.

[0057] It should be noted that the display module requires the display panel 21 to be bent, so an OLED display panel 21 can be used.

[0058] The display assembly may further include a cover plate 3, which is disposed on the display surface of the display panel 21. The cover plate 3 may be a glass cover plate 3, the side of the cover plate 3 close to the display module 2 is a flat surface, and the side of the cover plate 3 away from the display module 2 is a convex surface, that is, the thickness of the cover plate 3 gradually decreases in the direction away from the center. The edge of the orthographic projection of the display module 2 on the cover plate 3 is retracted relative to the edge of the cover plate 3. It can be understood that the position of the bending portion 2121 farthest from the support layer group 22 is at a certain distance from the edge of the cover plate 3.

[0059] The display assembly may further include a filling portion 4, which fills the gap between the non-display portion 212 and the side of the support layer group 22 inside the display module 2, and can enhance the strength of the display module 2. The filling portion 4 wraps the non-display area of ​​the display surface of the display module 2, the side of the display module 2, and the non-display surface of the display module 2, and the edge of the filling portion 4 can be flush with the edge of the cover plate 3.

[0060] The filling portion 4 includes a second flat surface 42 and a second inclined surface 41. The second flat surface 42 is located on the non-display side of the display panel 21. The second flat surface 42 is arranged along the second direction, the second direction is perpendicular to the first direction, and the angle between the second inclined surface 41 and the first direction can be 30 to 90 degrees. The side of the filling portion 4 also includes a third flat surface 43, and the third flat surface 43 and the side of the edge of the cover plate 3 and the side of the edge of the middle frame 1 are located in the same plane. The filling portion 4 is usually made of a flexible material, and when the cover plate 3 is subjected to external force (impact or extrusion), it can play a certain protective role on the edge of the cover plate 3. A second clamping portion is provided on the second inclined surface 41 for connecting with the first clamping portion on the middle frame. It should be noted that the first direction is the thickness direction of the display module 2.

[0061] A shading layer 6 is provided at the edge of the display panel 21, and the shading layer 6 is located between the filling part 4 and the cover plate 3 in the first direction. The orthographic projection of the shading layer 6 on the cover plate 3 overlaps with the orthographic projection of the non-display part 212 on the cover plate 3, and the orthographic projection of the shading layer 6 on the cover plate 3 covers the orthographic projection of the bending part 2121 on the cover plate 3.

[0062] like Figures 1 to 10 As shown, an embodiment of the present disclosure provides a display device, which includes the display component mentioned above. The structure of this part is the same as that of the above display component. The display device can refer to the display component mentioned above and will not be described in detail here.

[0063] The display device further includes a middle frame 1, the edge of the cover plate 3 is flush with the edge of the middle frame 1, the middle frame 1 has an installation notch 11, the display module 2 is arranged in the installation notch 11, the installation notch 11 includes a supporting surface 111 and a blocking surface 112 connected to each other, the blocking surface 112 is the end surface of the installation notch 11, the supporting surface 111 is the side surface of the installation notch 11, the side surface of the display module 2 is opposite to the blocking surface 112, and the non-display surface of the display module 2 is opposite to the supporting surface 111. The middle frame 1 and the cover plate 3 are flush, the increase in the frame of the display device caused by the middle frame 1 is eliminated, and the frame of the display device is significantly reduced.

[0064] In this embodiment, the blocking surface 112 includes a first inclined surface, and the angle between the first inclined surface and the first direction can be 30 degrees to 90 degrees. The supporting surface 111 extends along a second direction, and the second direction is perpendicular to the first direction. It can be understood that the angle between the first inclined surface and the supporting surface 111 is usually 0 degrees to 30 degrees.

[0065] The display device also includes a filling portion 4. Inside the display module 2, the filling portion 4 fills the gap formed between the non-display portion 212 and the side of the support layer group 22, which can enhance the strength of the display module 2. Between the display module 2 and the middle frame 1 and the cover plate 3, the filling portion 4 is filled in the area surrounded by the support surface 111, the blocking surface 112, the cover plate 3, the non-display area of ​​the display surface of the display module 2, the side of the display module 2, and the non-display surface of the display module 2. The middle frame 1 is provided with a first clamping portion, and the filling portion 4 is provided with a second clamping portion, and the second clamping portion is clamped together with the first clamping portion. There is no need to apply glue to the filling portion 4 and the middle frame 1, which eliminates the glue application and bonding process, and the interference fit has good sealing, high fixing strength, and higher assembly accuracy than adhesive bonding.

[0066] The surface of the filling part 4 opposite to the blocking surface 112 includes a second inclined surface 41. The angle between the second inclined surface 41 and the first direction is the same as the angle between the first inclined surface and the first direction. A first clamping portion is provided on the first inclined surface, and a second clamping portion is provided on the second inclined surface 41. The second clamping portion is clamped together with the first clamping portion.

[0067] The filling part 4 is filled between the cover plate 3 and the middle frame 1, and the side of the filling part 4 also includes a third flat surface 43, and the third flat surface 43 and the side of the edge of the cover plate 3 and the side of the edge of the middle frame 1 are located in the same plane. The filling part 4 is usually made of a flexible material, so it can play a certain buffering role between the cover plate 3 and the middle frame 1, and can play a certain protective role on the edge of the cover plate 3 when the cover plate 3 is subjected to external force (impact or extrusion).

[0068] A shading layer 6 is provided at the edge of the display panel 21, and the shading layer 6 is located between the filling part 4 and the cover plate 3 in the first direction. The orthographic projection of the shading layer 6 on the cover plate 3 overlaps with the orthographic projection of the non-display part 212 on the cover plate 3, and the orthographic projection of the shading layer 6 on the cover plate 3 covers the orthographic projection of the bending part 2121 on the cover plate 3.

[0069] like Figures 1 to 6 As shown, the first clamping portion is a first groove 71 provided on the middle frame 1 , and the second clamping portion is a first lug 74 provided on the filling portion 4 . The first lug 74 is adapted to the shape of the first groove 71 , and the first lug 74 can be interference fit in the first groove 71 .

[0070] In the direction away from the second inclined surface 41, the width of the first lug 74 gradually increases and then gradually decreases. The size of the filling portion 4 along the first direction can be 1.3-1.5 mm, the size of the filling portion 4 along the second direction can be 1.3-2 mm, the radius R of the first lug 74 can be set to 0.2 mm-0.4 mm, and the radius of the first groove 71 is 0.02 mm-0.05 mm smaller than the radius of the first lug 74.

[0071] like Figure 1 and Figure 2 As shown, the first lug 74 includes a first protruding portion 741 and a second protruding portion 742 sequentially arranged in a direction away from the second inclined surface 41, the width of the first protruding portion 741 gradually increases in the direction away from the first inclined surface, and the width of the second protruding portion 742 gradually decreases in the direction away from the first inclined surface. The increase in the width of the first protruding portion 741 is less than the decrease in the width of the second protruding portion 742.

[0072] In order to facilitate the first lug 74 to enter the first groove 71, the end of the second protrusion 742 away from the second inclined surface 41 is usually as small as possible, that is, the width of the end of the second protrusion 742 away from the second inclined surface 41 can be infinitely close to zero. In order to ensure the setting strength of the first lug 74, the width of the first protrusion 741 close to the second inclined surface should not be too small, otherwise the first protrusion 741 is easy to separate from the filling part 4.

[0073] like Figure 3 and Figure 4 As shown, the shape of the first lug 74 is an arc, the increase range of the width of the first protrusion 741 gradually decreases in the direction away from the first inclined surface, and the decrease range of the width of the second protrusion 742 gradually increases in the direction away from the first inclined surface. The structure of the first lug 74 is relatively smooth as a whole, and when the filling part 4 is connected to the middle frame 1, it is convenient for the first lug 74 to enter the first groove 71.

[0074] like Figure 5 and Figure 6 As shown, the first lug 74 includes a first protrusion 741 and a second protrusion 742 sequentially arranged in a direction away from the second inclined surface 41, and the first lug 74 includes a first protrusion 741 and a second protrusion 742 sequentially arranged in a direction away from the first inclined surface, and the width of the second protrusion 742 is always greater than the width of the first protrusion 741. It can be understood that the width of the first lug 74 changes in a step-like manner, and this structure can enhance the clamping degree of the first protrusion 741 and the second protrusion 742, and better prevent the first protrusion 741 from separating from the second protrusion 742. In this embodiment, both sides of the second protrusion 742 are set as convex arc surfaces, so that the first lug 74 can enter the first groove 71.

[0075] You can also Figures 7 to 10 As shown, the first clamping portion is a first lug 74 provided on the middle frame 1 , and the second clamping portion is a first groove 71 provided on the filling portion 4 . The first lug 74 is adapted to the shape of the first groove 71 , and the first lug 74 is interference fit in the first groove 71 .

[0076] like Figure 7 and Figure 8As shown, the first lug 74 includes a first protruding portion 741 and a second protruding portion 742 sequentially arranged in a direction away from the second inclined surface 41, and the width of the second protruding portion 742 is greater than the width of the first protruding portion 741. Because the middle frame 1 is usually made of metal or plastic, its deformation capacity is smaller than that of the filling portion 4. In order to facilitate the first lug 74 to be inserted into the first groove 71, the first lug 74 is provided with a cavity 711, and the cavity 711 passes through the first protruding portion 741 and at least part of the second protruding portion 742 in a direction perpendicular to the second inclined surface 41. When the second clamping portion is clamped with the first clamping portion, the first lug 74 is pressed toward the middle of the cavity 711, and the first lug 74 is released after entering the first groove 71, so that the first protruding portion 741 and the second protruding portion 742 can be clamped.

[0077] Fig. 9 , Fig.10 and Figure 1 , Figure 2 The embodiments are basically the same, except that the first clamping portion is set as the first lug 74 and the second clamping portion is set as the first groove 71 , which will not be described in detail here.

[0078] like Fig.11 As shown, the support surface 111 includes a first flat surface, and the surface of the filling part 4 opposite to the first flat surface includes a second flat surface 42. The first flat surface and the second flat surface 42 are both arranged along the second direction, and the second direction is perpendicular to the first direction. A third clamping portion can be arranged on the first flat surface, and a fourth clamping portion can be arranged on the second flat surface 42. The fourth clamping portion and the third clamping portion are clamped together, which can further enhance the reliability of the connection between the filling part 4 and the middle frame 1. The third clamping portion can be a second lug 75 arranged on the first flat surface, and the fourth clamping portion can be a second groove 72 arranged on the second flat surface 42. The second lug 75 is interference-fitted in the second groove 72.

[0079] In order to further enhance the connection reliability between the filling part 4 and the middle frame 1, the number of first clamping parts can be increased along the extension direction of the first inclined surface, and the corresponding number of second clamping parts can be increased on the second inclined surface 41. The number of third clamping parts can also be increased along the first straight surface, and the number of fourth clamping parts can be increased on the second straight surface 42.

[0080] like Fig.12As shown, the support layer group 22 is provided with a fifth clamping portion, the filling portion 4 has a sixth clamping portion, and the fifth clamping portion and the sixth clamping portion are clamped together. The connection strength between the filling portion 4 and the display module 2 can be enhanced, the filling portion 4 and the display module 2 can be prevented from being separated, and the reliability of the connection between the display module 2 and the middle frame 1 is enhanced. The edge of the adhesive layer 223 is away from the bending area of ​​the non-display portion 212 relative to the edge of the heat dissipation film 222. The fifth clamping portion is provided on the heat dissipation film 222 and is located between the edge of the adhesive layer 223 and the edge of the heat dissipation film 222. The fifth clamping portion can be a third groove 73 provided on the heat dissipation film 222, and the sixth clamping portion can be a third lug 76 provided on the filling portion 4, and the third lug 76 is interference fit in the third groove 73.

[0081] The filling part 4 can be formed by injection molding, which is to flow liquid material into the gap formed between the non-display part 212 and the side of the support layer group 22, and wrap the non-display area of ​​the display surface of the outer surface of the display panel 21, the side of the display module 2, and the non-display surface of the display module 2, and solidify the liquid material flowing into the mold. It can be understood that the parts of the filling part located on both sides of the display panel 21 are made of the same material.

[0082] The parts of the filling part 4 located on both sides of the display panel 21 are the first sub-filling part 401 and the second sub-filling part 402, respectively. The first sub-filling part 401 and the second sub-filling part 402 can be formed by different processes, for example: the first sub-filling part 401 can be formed on the inner surface of the display panel 21 by an injection molding process, or the pre-formed first sub-filling part 401 can be installed on the side of the support layer group 22, and then the display panel is bound. Other processes can also be used, which are not listed here one by one. In this embodiment, the second sub-filling part 402 on the outer surface of the display panel 21 is formed by a 3D printing process, that is, the second sub-filling part 402 is a 3D printed component. It can be understood that since the manufacturing processes of the first sub-filling part 401 and the second sub-filling part 402 are different, different materials can be used.

[0083] The second sub-filling portion 402 needs to be formed with a second clamping portion, and even a fourth clamping portion and a sixth clamping portion, so the structure of the second sub-filling portion 402 is relatively complex. Even if the second sub-filling portion 402 is a complex special-shaped structure, the 3D printing component can be easily realized. Compared with the second sub-filling portion 402 formed by the injection molding process, the 3D printing component can form a more complex special-shaped structure, and there is no need to make a corresponding molding mold, so the cost is low.

[0084] like Fig.13 As shown, the blocking surface 112 may also be configured as a vertical surface, and the vertical surface extends along the first direction.

[0085] A concave arc-shaped notch 1121 is provided on the blocking surface 112, the width of the arc-shaped notch 1121 is greater than the thickness of the display module 2, the display module 2 is at least partially located in the arc-shaped notch 1121, the filling portion 4 is located between the bending portion 2121 of the display module 2 and the arc-shaped notch 1121, the first clamping portion is located in the arc-shaped notch 1121, and the second clamping portion is located on the arc surface opposite to the filling portion 4 and the arc-shaped notch 1121. In this way, the frame of the display device can be further reduced. Because the arc-shaped notch 1121 can play a certain limiting role, the size of the first clamping portion and the second clamping portion can be appropriately reduced, which can further reduce the frame of the display device.

[0086] like Fig.14 As shown, the display device further includes a stopper 5, and the stopper 5 is made of a material with good strength and can be processed into an ultra-thin structural member, for example, the stopper 5 is made of stainless steel. The stopper 5 can be arranged at the edge of the display device, and the stopper 5 has a first stopper section 51, a second stopper section 52 and a third stopper section 53. The first stopper section 51 extends along the first direction, the second stopper section 52 is arranged at one end of the first stopper section 51 close to the cover plate 3, and is perpendicular to the first stopper section 51, and the third stopper section 53 is arranged at one end of the first stopper section 51 close to the middle frame 1. The first stopper section 51 is bonded to the filling portion 4, and an installation groove is arranged at the edge of the cover plate 3, and part of the first stopper section 51 and the second stopper section 52 are inserted into the installation groove, and the third stopper section 53 is inserted into the filling portion 4.

[0087] The mounting groove may include a first notch, the first notch extending in the thickness direction of the cover plate 3, the first limiting section 51 is partially disposed in the first notch, and the first limiting section 51 is attached to the side of the first notch. In order to prevent the connection between the first limiting section 51 and the first notch from loosening when the display device is subjected to frequent vibrations, causing the limiting member 5 and the cover plate 3 to fall off. A second notch is also provided on the side of the first notch, and the second notch extends perpendicularly to the thickness direction of the cover plate 3. The second limiting section 52 is snapped into the second notch. By cooperating with the second limiting section 52 and the second notch, the movement of the cover plate 3 in its thickness direction can be limited.

[0088] However, the hardness and wear resistance of the cover plate 3 are usually lower than those of the support member. In order to prevent the support member from directly contacting the cover plate 3 and affecting the strength of the cover plate 3, the cross-sectional shape of the second notch can be set to a circular arc, and the cross-sectional shape of the third supporting segment is set to a circular arc that matches the shape and size of the second notch. When the display device is vibrated, the contact area between the first segment and the second notch can be increased, so that the cover plate 3 is not easily damaged.

[0089] like Fig.15As shown, a flexible buffer layer 54 may be provided between the third support segment and the second notch. The flexible buffer layer 54 is generally made of an elastic material that deforms when subjected to force and returns to its original state when the force disappears, and may specifically be foam. It is to be understood that foam is merely an exemplary description of the flexible buffer layer 54 and does not constitute a limitation on the flexible buffer layer 54.

[0090] It should be noted that, in addition to the middle frame 1 and the display panel 21, the display device also includes other necessary components and components, such as a housing, a circuit board, a power cord, etc. Those skilled in the art can make corresponding supplements according to the specific use requirements of the display device, which will not be repeated here.

[0091] The display device can be a traditional electronic device, such as a mobile phone, a watch, a computer, a television, and a camcorder, or it can be an emerging wearable device, such as VR glasses, which are not listed here one by one.
