DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] With the continuous advancement of technology, users' demand for a higher screen-to-body ratio of electronic devices is increasing. Currently, the edge of the screen module of an electronic device needs to have a certain safety distance from the middle frame to prevent the edge of the screen module from being damaged by collision, extrusion, etc.

[0046] For example, Figure 1 As shown, the screen module 1 adopts a flexible display screen. According to the soft and bendable performance of the flexible display screen, the part of the flexible display screen near the lower edge is bent backward to form a bending area 112, thereby reducing the frame width. The screen module 1 is usually bonded to the middle frame 2 through the cover plate 13, so that the screen module 1 is fixed to the middle frame 2. At this time, the frame width L is composed of three parts. The first part (such as Figure 1 A) shown in the figure is the width of at least part of the bending area 112 of the screen module 1, and the second part (such as Figure 1 B) shown in the figure is to leave a certain safety distance for the bending area 112, that is, the width of the avoidance gap, which can prevent the bending area 112 from being damaged by impact, extrusion, collision, etc. during the assembly process, thereby affecting the reliability of the screen module 1. The third part (such as Figure 1 C) shown in the figure is a fixed width for connecting and fixing the screen module 1 to the middle frame 2. It can be understood that the frame width refers to the distance from the edge of the display area of ​​the display screen to the middle frame of the electronic device.

[0047] In order to solve the above technical problems, the present disclosure provides a screen module in which a protective structure is provided. The protective structure extends along at least one side of the display panel. The protective structure covers the edge area of ​​the display panel on the side where the protective structure is provided, effectively preventing the edge area of ​​the display panel from being damaged by impact, extrusion, etc., thereby improving the reliability of the display panel. At the same time, there is no need to leave a safe distance for the edge area of ​​the display panel, and the width of the frame can be reduced on the side where the protective structure is provided, thereby improving the screen-to-body ratio of the electronic device.

[0048] An exemplary embodiment of the present disclosure provides a screen module, such as Figure 5As shown, the screen module 1 includes a display panel 11 and a protective structure 12. The protective structure 12 extends along at least one side of the display panel 11. Exemplarily, the display panel 11 is rectangular and has four sides. The protective structure 12 can be arranged on one of the sides and extend along the length direction of the side. It can also be arranged on four sides. The protective structure 12 on each side extends along the length direction of its corresponding side. The protective structure 12 covers the edge area of ​​the display panel 11 on that side to avoid damage to the edge area of ​​the display panel 11 due to impact, extrusion, etc., thereby effectively improving the reliability of the display panel 11. It can be understood that the protective structure 12 covers the edge area of ​​the display panel 11 on that side, which means that the protective structure 12 wraps the edge area of ​​the display panel 11 and covers the surface of the edge area.

[0049] In this embodiment, the edge area of ​​the display panel 11 is protected by setting a protective structure 12. There is no need to set a safety distance for the edge area of ​​the display panel 11. The border width can be reduced on the side where the protective structure is set, thereby increasing the screen-to-body ratio of the electronic device.

[0050] In one embodiment, if Figure 2 As shown, the display panel 11 includes a body 111, and a bending area 112 is provided on at least one side of the body 111. Exemplarily, the display panel 11 is a flexible display panel with bendability, and the bending area 112 is provided on at least one side of the body 111. For example, the bending area 112 is provided on one side of the body 111, or the bending area 112 can be provided on each side of the body 111. By providing the bending area 112, the frame width on the side where the bending area 112 is located can be further reduced, thereby increasing the screen-to-body ratio of the electronic device.

[0051] like Figure 5 As shown, the protective structure 12 at least covers the bending area 112. For example, the protective structure 12 only covers the bending area 112, and can also cover at least part of the body 111 near the bending area 112 while covering the bending area 112. With such a design, while protecting the bending area 112, there is no need to set an avoidance gap for the bending area 112, so that the frame width on the side where the bending area 112 is located can be further reduced, thereby increasing the screen-to-body ratio of the electronic device.

[0052] In one embodiment, the width of the bending area 112 is smaller than the width of the body 111. For example, Fig.14 As shown, the display panel 11 includes a body 111 and a fan-out area 113 connected to the body 111. The fan-out area 113 is used to bend to form a bending area 112. The width L1 of the fan-out area 113 is smaller than the width L2 of the body 111, that is, the width of the bending area 112 is smaller than the width of the body 111. Figure 5As shown, the protective structure 12 extends from the bending area 112 to both sides to cover the edge areas of the body 111 located on both sides of the bending area 112. Exemplarily, a bending area 112 is set on one side of the body 111, and the bending area 112 is located in the middle area of ​​the side. Along the length direction of the side, the protective structure 12 extends from the bending area 112 to both sides of the body 111, thereby covering the edge areas of the body 111 located on both sides of the bending area 112. Such a design can improve the comprehensiveness of the protection of the side where the protective structure 12 is located, and further improve the reliability of the screen module 1.

[0053] Continue to refer Figure 5 In one embodiment, the thickness of the protective structure 12 in the bending area 112 is greater than the thickness of the protective structure 12 in the main body 111. With such a setting, the protective effect of the bending area 112 is improved while reducing the use of materials of the protective structure 12, which can not only reduce production costs but also is conducive to the lightweight design of electronic equipment.

[0054] Continue to refer Figure 5 In one embodiment, the display panel includes a first surface 114 and a second surface 115 opposite to each other, the body 111 of the display panel 11 includes a first side edge, and the bending area 112 is connected to the first side edge. The protective structure 12 includes a first protective portion 121 and a second protective portion 122 connected to each other, the first protective portion 121 covers the edge area of ​​the first surface 114 on the side where the first side edge is located, and the second protective portion 122 covers the first surface located at the bending area 112. With such a design, the edge area on the side where the bending area 112 is located can be protected, thereby improving the reliability of the screen module 1.

[0055] Continue to refer Figure 5 In one embodiment, the display panel 11 further includes an extension area 116 connected to the bending area 112, and the extension area 116 is used to connect to, for example, a mainboard of an electronic device, so as to control the display of the display panel 11. The protective structure 12 further includes a filling portion 123 and a third protective portion 124, the third protective portion 124 is connected to the second protective portion 122 and covers at least a portion of the first surface 114 located in the extension area 116, and the filling portion 123 fills the space enclosed by part of the body 111, the bending area 112 and part of the second surface 115 of the extension area 116. Such a design effectively improves the comprehensiveness of the protection of the bending area 112 and the edge area on the side where the bending area 112 is located, and can further improve the reliability of the screen module 1. Exemplarily, the first protective part 121, the second protective part 122, the third protective part 124 and the filling part 123 are an integrally formed structure, for example, by pouring liquid glue, and the liquid glue is cured to form an integral structure of the protective structure 12. Such a setting form facilitates the processing and manufacturing of the protective structure 12.

[0056] In one embodiment, if Figure 8 As shown, the body 111 also includes a second side, and the protective structure 12 also includes a fourth protective portion 125, a fifth protective portion 126, and a first connecting portion 127 connecting the fourth protective portion 125 and the fifth protective portion 126. The fourth protective portion 125 covers the edge area of ​​the first surface 114 on the side where the second side is located, and the fifth protective portion 126 covers the edge area of ​​the second surface 115 on the side where the second side is located. At this time, the first connecting portion 127 covers the side surface between the first surface 114 and the second surface 115. With such a design, the edge area of ​​the other sides of the display panel 11 where the bending area 112 is not provided is protected, thereby improving the comprehensiveness and protection effect of the edge area of ​​the display panel 11, and further improving the reliability of the screen module 1.

[0057] In one embodiment, if Figure 2 As shown, the screen module 1 also includes a cover plate 13, which may be, for example, a glass cover plate. The cover plate 13 is provided to protect the display panel 11. The display panel 11 is provided on the back side of the cover plate 13. Along the thickness direction of the electronic device, the projection of the display panel 11 on the cover plate 13 is located inside the cover plate 13. It can be understood that the projection of the display panel 11 on the cover plate 13 is a positive projection. In this way, the protective effect of the cover plate 13 on the display panel 11 can be improved. In addition, the edge of the cover plate 13 has a preset distance from the edge of the display panel 11, and the preset distance can be used to connect with the middle frame 2 of the electronic device to facilitate the fixation of the screen module 1. As shown Figure 5 As shown, the protective structure 12 contacts the back of the cover plate 13 while covering the edge area of ​​the screen module 1. Such a setting can fix the protective structure 12 and prevent the protective structure 12 from shifting or falling off, thereby effectively improving the reliability of the screen module 1.

[0058] In one embodiment, if Figure 5As shown, the protective structure 12 can be a colloid structure formed by curing glue, and the glue can be, for example, UV (Ultraviolet Rays) glue, epoxy resin glue, PUR (Polyurethane Reactive) glue, etc. For example, the colloid structure can be formed by injecting glue into the edge area of ​​the screen module 1, and the glue is cured. It can also be that a containing space is set in the edge area of ​​the colloid structure corresponding to the screen module 1, and the edge area of ​​the screen module 1 is embedded in the containing space. Such a design, on the one hand, is convenient for processing and manufacturing the protective structure 12, and reduces the processing cost. On the other hand, the colloid structure has a certain elasticity, which can improve the protective effect and avoid the protective structure 12 itself from causing damage to the screen module 1. At the same time, the weight of the colloid structure is relatively light, which is conducive to the lightweight design of electronic equipment. In another embodiment, the protective structure 12 can also be a polymer material piece, and the polymer material can be, for example, rubber, adhesive, etc. The protective structure 12 can also be a foaming structure.

[0059] In one embodiment, if Fig. 9 As shown, the back of the display panel 11 partially covered by the protective structure 12 has a step structure 14. Exemplarily, the display panel 11 includes a multi-layer structure, such as a touch layer, a display layer, etc. The areas of each layer are different, so that the edge area of ​​the two adjacent layers forms a step structure 14. The step structure 14 includes at least two step surfaces, and at least two step surfaces are arranged along the extension direction of the side of the display panel 11 where the step structure 14 is located. There is a gap between adjacent layers. When the protective structure 12 is formed by glue injection, the glue can easily enter the screen module 1 through the gap, thereby affecting not only the neatness of the screen module 1, but also the normal use of the screen module 1. It can be understood that the extension direction of the side refers to the length direction of the side.

[0060] Based on this, Fig.12 As shown, in this embodiment, the screen module 1 further includes a blocking structure 15, which covers the step structure 14 in the extension direction. With such a design, on the one hand, the gap generated at the step structure 14 is sealed by the blocking structure 15 to prevent glue from entering the screen module 1 from the gap, thereby effectively improving the reliability of the screen module 1. On the other hand, the blocking structure 15 is located on the back of the display panel 11, and the blocking structure 15 can also protect the back of the screen module 1 to a certain extent, preventing the back of the screen module 1 from being damaged due to extrusion or impact.

[0061] Exemplarily, the blocking structure 15 may also be a rubber block.

[0062] An exemplary embodiment of the present disclosure provides an electronic device, which may be, for example, a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., and may also be a non-mobile device such as a personal computer (PC), a television (TV), a teller machine, or a self-service machine.

[0063] like Figure 5 As shown, the electronic device includes a middle frame 2 and the screen module 1 as described above, and the screen module 1 is fixed to the middle frame 2. The screen module 1 includes a display panel 11 and a protective structure 12, the protective structure 12 extends along at least one side of the display panel 11, and the protective structure 12 covers the edge area of ​​the display panel 11 on the side to prevent the edge area of ​​the display panel 11 from being damaged due to impact, extrusion, etc., thereby effectively improving the reliability of the display panel 11. By setting the protective structure 12 to protect the edge area of ​​the display panel 11, there is no need to set a safety distance for the edge area of ​​the display panel 11, and the width of the frame 22 can be reduced on the side where the protective structure 12 is set, thereby improving the screen-to-body ratio of the electronic device.

[0064] In one embodiment, if Figure 6 As shown, the middle frame 2 includes a middle frame body 21 and a frame 22 surrounding the edge of the middle frame body 21. Each frame 22 and the middle frame body 21 together define a housing cavity. The screen module 1 is fixed to the middle frame 2, and the display panel 11 of the screen module 1 is located in the housing cavity. The inner side of the frame 22 is protrudingly provided with a second connection portion 221. The second connection portion 221 is arranged opposite to the back edge area of ​​the cover plate 13 of the screen module 1. When the screen module 1 is assembled on the middle frame 2, the back edge area of ​​the cover plate 13 is placed on the second connection portion 221. On the one hand, the second connection portion 221 can support the screen module 1 to prevent the back of the screen module 1 from impacting the middle frame body 21 and thus causing damage to the screen module 1. On the other hand, the setting of the second connection portion 221 facilitates the connection and fixation between the screen module 1 and the middle frame 2, so that the back edge area of ​​the cover plate 13 and the second connection portion 221 can be bonded by glue, thereby improving the assembly convenience and assembly efficiency of the electronic device.

[0065] In another embodiment, if Figure 7As shown, the middle frame 2 includes a middle frame body 21 and a frame 22 surrounding the edge of the middle frame body 21. Each frame 22 and the middle frame body 21 together define a containing cavity. The screen module 1 is fixed to the middle frame 2, and the display panel 11 of the screen module 1 is located in the containing cavity. The side of the protective structure 12 facing away from the cover plate 13 is bonded to the middle frame body 21, thereby achieving fixation between the screen module 1 and the middle frame 2. With such a design, there is no need to provide a second connecting portion 221 protruding from the inner side surface of the frame 22 for fixing the screen module 1, thereby further reducing the distance between the edge of the display area of ​​the display panel 11 and the corresponding frame 22, thereby further improving the screen-to-body ratio of the electronic device. Furthermore, in this embodiment, as Figure 7 As shown, the inner side surface of the frame 22 can be a flat surface or a smooth curved surface, which can further reduce the width of the frame.

[0066] An exemplary embodiment of the present disclosure provides a mold (such as Figure 3 The first mold 3 shown in the figure is used to form a protective structure 12 on the screen module 1. For the convenience of description, the mold is referred to as the first mold 3 below. Figure 3 The first mold 3 includes a first matching portion 31 for abutting against the edge of the cover plate 13 of the screen module 1, a second matching portion 32 abutting against the back of the display panel 11 of the screen module 1, and a third connecting portion 33 connecting the first matching portion 31 and the second matching portion 32. The first mold 3 is used to cooperate with the screen module 1 to form a first mold cavity 34 for accommodating at least part of the side edge of the display panel 11. Exemplarily, the first matching portion 31 is a frame structure adapted to the cover plate 13, so that the cover plate 13 is embedded in the frame structure, the edge of the cover plate 13 abuts against the inner side of the frame structure, and each edge of the frame extends in a direction away from the cover plate 13 to exceed the height of the display panel 11. It can be understood that the height of the display panel 11 is also the thickness of the display panel 11. One end of the second matching portion 32 abuts against the back of the display panel 11, and the other end of the second matching portion 32 is connected to the first matching portion 31 through the third connecting portion 33, and then the first matching portion 31, the third connecting portion 33 and the second matching portion 32 can be enclosed together to form a first mold cavity 34, and the first mold cavity 34 and the screen module 1 form a sealed cavity. The bending area 112 of at least one side of the display panel 11 and at least part of the body 111 are located in the first mold cavity 34. Exemplarily, the first mold 3 can be provided with a second matching portion 32 and a third connecting portion 33 corresponding to one side of the display panel 11, so as to form a first mold cavity 34 on the side. The first mold 3 can also form a first mold cavity 34 corresponding to each side of the display panel 11.

[0067] The first mold 3 is provided with a pouring port 35 connected to the first mold cavity 34, and glue (such as Figure 4The first glue 36 shown in the figure is used to fill the first mold cavity 34 with the glue. Figure 5 As shown, when the glue is cured, the protective structure 12 is formed. In this embodiment, the number of the injection port 35 can be one, and one injection port 35 can be located on the first matching portion 31, the second matching portion 32 or the third connecting portion 33. The number of the injection port 35 can also be multiple, for example, the first matching portion 31, the second matching portion 32 and the third connecting portion 33 are all provided with the injection port 35.

[0068] In this embodiment, the side of the screen module 1 where the protective structure 12 is required is first sealed by the first mold 3, and then the protective structure 12 is formed by glue filling. Such a design, on the one hand, can effectively prevent the glue from flowing into the inside of the screen module 1 or even the inside of the electronic device, thereby improving the reliability of the electronic device. On the other hand, the method of forming the protective structure 12 as described above is simple and easy to operate, which effectively solves the problem that it is difficult to set the protective structure 12 due to the complex structure of the edge area of ​​the screen module 1, thereby effectively improving the efficiency and convenience of processing the protective structure 12.

[0069] In one embodiment, if Figure 3 As shown, when the back of the display panel 1 of the screen module 1 has a step structure 14, the screen module 1 is also provided with a blocking structure 15, and the blocking structure 15 covers the step structure 14 in the extension direction. Based on this, a partial area of ​​the second matching portion 32 is provided with a matching groove, and the matching groove is used to match with the blocking structure 15 of the screen module 1. Exemplarily, after the first mold 3 is assembled to the screen module 1, the blocking structure 15 is embedded in the matching groove. With such a setting form, on the one hand, the sealing performance when the second matching portion 32 is connected to the back of the screen module 1 is improved, and the leakage of glue is avoided. On the other hand, the second matching portion 32 is pressed against the blocking structure 15, which can also protect the back of the screen module 1, preventing the second matching portion 32 from directly pressing against the screen module 1 and causing damage to the screen module 1, thereby improving the reliability of the screen module 1.

[0070] In one embodiment, the first mold 3 is made of an elastic material, such as a silicone material, so that the first mold 3 is easily assembled with the screen module 1 and effectively prevents the first mold 3 from causing damage to the screen module 1, thereby ensuring the reliability of the screen module 1.

[0071] An exemplary embodiment of the present disclosure provides a mold (such as Fig.10 The second mold 4 shown in the figure is used to form a blocking structure 15 on the screen module 1. For the convenience of description, the mold is referred to as the second mold 4 below. Fig. 9As shown, the back of the display panel 11 of the screen module 1 has a step structure 14.

[0073] First, pour glue (such as Fig.11 Before the glue is completely cured, the second mold 4 is assembled on the screen module 1 so that the glue in the second mold cavity covers the step structure 14 and the glue in the second mold cavity forms a shape that matches the step structure 14. Fig.12 As shown, when the glue is completely cured, a barrier structure 15 is formed.

[0074] Compared with directly injecting glue into the step structure 14 to form the blocking structure 15 , such a setting can effectively prevent glue from entering the screen module 1 through the gap of the step structure 14 , thereby improving the reliability of the screen module 1 .

[0075] The blocking structure 15 is provided to seal the gap generated at the step structure 14, so as to prevent the glue from entering the screen module 1 from the gap when the protective structure 12 is formed, thereby effectively improving the reliability of the screen module 1. At the same time, the blocking structure 15 is located on the back of the display panel 11, and the blocking structure 15 can also protect the back of the screen module 1 to a certain extent, and prevent the back of the screen module 1 from being damaged due to extrusion or impact.

[0086] In this embodiment, the first mold 3 is used to seal the side of the initial screen module where the protective structure 12 is required, and then the protective structure 12 is formed by glue injection. Such a design, on the one hand, can effectively prevent the first glue 36 from flowing into the initial screen module or even into the electronic device, thereby improving the reliability of the electronic device. On the other hand, the screen module processing method in this embodiment is simple and easy to operate in processing the protective structure 12, which effectively solves the problem that it is difficult to set the protective structure 12 due to the complex structure of the edge area of ​​the screen module 1, thereby effectively improving the efficiency and convenience of processing the protective structure 12.

[0087] In addition, by providing the protection structure 12 to protect the edge area of ​​the display panel 11, there is no need to set a safety distance for the edge area of ​​the display panel 11, which can further reduce the width of the frame 22, thereby further improving the screen-to-body ratio of the electronic device.

[0100] In this step, after the second glue 44 is completely cured, the second mold 4 is removed to facilitate the subsequent formation of the protective structure 12 .

[0101] In this embodiment, compared with directly injecting glue into the step structure 14 to form the blocking structure 15 , the glue is effectively prevented from entering the initial screen module through the gap of the step structure 14 , thereby improving the reliability of the screen module 1 .
