Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of display, and in particular, to an electronic device. BACKGROUND

[0002] In the preparation and packaging process of the display screen, the edge of the display screen inevitably forms a black border. The black border of the display screen does not have display function, and the excessively wide black border will affect the visual experience of the user.

[0003] Due to the limitation of the minimum trace width at the rounded corner of the display screen, it is more difficult to reduce the black border width at the rounded corner. In addition, if the black border width at the straight edge of the display screen is set to be small and the black border width at the rounded corner is set to be large, the black border width around the display screen will be uneven and uncoordinated, affecting the user experience. SUMMARY

[0004] The present application provides an electronic device, which can reduce the black border width at the rounded corner of the display screen and ensure the sealing of the electronic device.

[0005] In a first aspect, an electronic device is provided, comprising a middle plate, a side frame, a display screen, a first glue, a second glue and a third glue,

[0007] The first glue filling hole is a through hole provided on the middle plate along the first direction, the first glue filling hole and the second surface respectively overlap along the normal projection of the first direction, and the distance between the center of the first glue filling hole and the connecting plane of the first rounded corner frame and the non-rounded corner frame is less than the radius of the first glue filling hole, and the first direction is perpendicular to the bottom surface of the display screen;

[0008] The display screen comprises a cover plate and a display panel, the cover plate covers the display panel, and the cover plate and the display panel are connected, the display panel is located between the cover plate and the middle plate, the display panel comprises a bending portion, the bending portion is bent on the bottom surface of the display panel, and the bending portion is arranged to avoid the first glue filling hole,

[0009] The first glue is used to connect the non-rounded corner frame and the display screen;

[0010] The second glue is used to connect the first bevel frame and the display screen or used to connect the middle plate and the display screen.

[0011] The third glue connects the first glue and the second glue through the first glue filling hole.

[0012] The application provides an electronic device. In one aspect, the first bevel frame and the non-bevel frame do not meet at the bevel, that is, there is no two different structures at the bevel, which is conducive to reducing the black border width at the bevel of the display screen, and further, can make the black border width of the periphery of the display screen uniform. In another aspect, since the first glue filling hole and the second surface of the non-bevel frame respectively overlap along the first direction, and the distance between the center of the first glue filling hole and the connecting plane of the first bevel frame and the non-bevel frame is less than the radius of the first glue filling hole, the third glue can effectively connect the first glue and the second glue through the first glue filling hole, thereby ensuring the sealing of the electronic device.

[0013] In combination with the first aspect, in a possible implementation manner, the first bevel frame comprises a bevel edge portion and a straight edge portion connected to the bevel edge portion, the straight edge portion of the first bevel frame and a side away from the bevel edge portion are connected to the non-bevel frame,

[0014] The first glue filling hole is located at the meeting place of the straight edge portion of the first bevel frame and the non-bevel frame along the first direction.

[0015] That is, the first glue filling hole is completely located at the straight edge of the side frame and not at the bevel of the side frame, which is conducive to reducing the black border width at the bevel and ensuring the sealing of the electronic device.

[0016] In combination with the first aspect, in a possible implementation manner, the first bevel frame comprises an inner side and a step portion protruding from the inner side, the step portion comprises a step top surface and a step side surface, and the step top surface is connected to the inner side; the cover plate comprises a bottom surface and a side surface, and the display panel comprises a bottom surface and a side surface;

[0017] The second glue comprises a first portion, a second portion, a third portion and a fourth portion, the first portion is connected to the second portion, the second portion is connected to the third portion, and the third portion is connected to the fourth portion.

[0018] The first portion of the second glue is arranged between the inner side and the side surface of the cover plate, the second portion of the second glue is arranged between the step top surface and the bottom surface of the cover plate, the third portion of the second glue is arranged between the side surface of the display panel and the step side surface, and the fourth portion of the second glue is arranged between the bottom surface of the display panel and the middle plate.

[0019] Since the second glue can be in contact with the side surface and the bottom surface of the display panel, the length of the glue dispensing path is increased, the sealing of the electronic device is ensured, and thus the width of the step part protruding from the inner side surface can be reduced, thereby reducing the black border width at the first rounded corner frame.

[0020] In a possible implementation manner of the first aspect, the first glue dispensing hole overlaps the projection of the step part along the first direction.

[0021] That is, the projection of the first glue dispensing hole along the first direction overlaps the projection of the second surface of the non-rounded corner frame along the first direction, and the projection of the first glue dispensing hole along the first direction overlaps the projection of the step part of the first rounded corner frame along the first direction. The projection overlap can be partial overlap or complete overlap. In this way, the third glue can effectively connect the first glue and the second glue through the first glue dispensing hole, and the sealing of the electronic device is ensured.

[0022] In a possible implementation manner of the first aspect, the first rounded corner frame includes an inner side surface, the cover plate includes a bottom surface and a side surface, and the display panel includes a bottom surface and a side surface.

[0023] The second glue includes a first part, a second part and a third part, the first part is connected with the second part, and the second part is connected with the third part.

[0024] The first part of the second glue is arranged between the side surface of the cover plate and the inner side surface, the second part of the second glue is arranged between the side surface of the display panel and the inner side surface, and the third part of the second glue is arranged between the bottom surface of the display panel and the middle plate.

[0025] Since the second glue can be in contact with the side surface and the bottom surface of the display panel, the length of the glue dispensing path is increased, the sealing of the electronic device is ensured, and thus the step part of the first rounded corner frame can be cancelled, thereby reducing the black border width at the rounded corner.

[0027] Since the second glue can be directly attached between the bottom surface of the display panel and the middle plate, a glue dispensing platform is not needed, and thus the black border at the rounded corner can be reduced.

[0028] In a possible implementation manner of the first aspect, the second glue is waterproof adhesive.

[0029] With reference to the first aspect, in a possible implementation manner, the side frame further includes a second round-corner frame and a second glue-filling hole, the second round-corner frame and the first round-corner frame are of the same structure, one end of the first round-corner frame is connected with the non-round-corner frame, the other end of the second round-corner frame is connected with the non-round-corner frame,

[0030] The second glue-filling hole is a through hole provided on the middle plate along the first direction, the second glue-filling hole and the second face respectively overlap in the orthogonal projection along the first direction, and the distance between the center of the second glue-filling hole and the connection plane of the second round-corner frame and the non-round-corner frame is less than the radius of the second glue-filling hole, and the first part of the bending part is located between the first glue-filling hole and the second glue-filling hole.

[0031] Since the bending part is relatively fragile, the first part of the bending part is located between the two glue-filling holes, so that the third glue body can be prevented from contacting the bending part through the glue-filling hole and damaging the bending part.

[0032] With reference to the first aspect, in a possible implementation manner, the first part of the bending part is connected with the display area of the display panel, the length of the first part in the X direction is less than the distance between the two glue-filling holes, and the length of the first part in the Y direction is greater than the diameter of the glue-filling hole.

[0033] With reference to the first aspect, in a possible implementation manner, the first part of the bending part is connected with the display area of the display panel, the length of the first part in the X direction is less than the distance between the two glue-filling holes, and the length of the first part in the Y direction is greater than the diameter of the glue-filling hole.

[0034] With reference to the first aspect, in a possible implementation manner, the cover plate includes an inclined side surface and a bottom surface.

[0035] The first glue body includes a first part and a second part connected to the first part.

[0036] The first part of the first glue body is arranged between the second face and the bottom surface of the cover plate, and the second part of the first glue body is arranged between the second face and the inclined side surface of the cover plate.

[0054] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0055] Figure 1 This is a schematic diagram of the structure of an electronic device provided by an embodiment of the present application, including mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (UMPCs), handheld computers, netbooks, personal digital assistants (PDAs), wearable devices, virtual reality devices, etc. Figure 1 The illustrated embodiment is described by taking a mobile phone as an example of the electronic device.

[0056] The electronic device 100 may include a display screen 110 and side frames 120. The display screen 110 may display information input by a user or information provided to a user, as well as various menus of the electronic device 100, and may also accept user input. The display screen 110 may include a display panel 111 and a cover plate 112, wherein the cover plate 112 covers the display panel 111.

[0057] The display panel 111 can integrate display and touch functions. The cover plate 112 can be light-transmissive and have functions such as impact resistance, scratch resistance, oil resistance, anti-fingerprint, and enhanced light transmittance. By way of example and not limitation, the cover plate 112 can be ultra-thin flat glass, curved glass, or ultra-thin flexible glass, or it can be transparent polyimide, a transparent resin material, or a transparent plastic. In other words, any material that can transmit light can be used as the cover glass.

[0058] The side frame 120 surrounds the outer periphery of the display screen 110. The side frame 120 can be a metal shell, such as a magnesium alloy, aluminum alloy, or stainless steel, or an alloy shell, such as a magnesium-aluminum alloy, or a plastic shell, a glass shell, a ceramic shell, etc., but is not limited thereto.

[0059] In some embodiments, the electronic device 100 may further include a back cover ( Figure 1 The display screen 110 and the back cover are arranged parallel to each other and spaced apart. The display screen 110 and the back cover are respectively mounted on both sides of the side frame 120. The side frame 120 and the back cover can be an integrally formed structure or can be assembled (e.g., by snap connection, bonding, etc.) to form an integral structure.

[0060] The side frame 120 surrounds the periphery of the display screen 110 and the periphery of the back cover. The cavity formed between the display screen 110, the side frame 120 and the back cover can be used to place components such as power supplies, electronic devices, and circuit boards.

[0061] Figure 2 Yes Figure 1An exploded view of the electronic device 100 is shown. As shown Figure 2 The display screen 110 includes a cover plate 112 and a display panel 111 fixed to the cover plate 112. The cover plate 112 covers the display panel 111, and the display panel 111 is located on the side of the cover plate 112 facing the middle plate 130.

[0062] The electronic device 100 can also include a middle plate 130. The middle plate 130 can be provided with one or more positioning structures such as positioning posts and positioning holes, which are used to fix the components of the electronic device 100 that are installed in the internal cavity of the whole machine. The middle plate 130 is fixed to the inner side of the side frame 120, and the middle plate 130 and the side frame 120 together form the middle frame of the electronic device 100. The middle plate 130 and the side frame 120 can be integrally formed.

[0063] The electronic device 100 can also include a gel assembly 140, which is roughly frame-shaped and slightly smaller than the side frame 120. In one example, the gel assembly 140 can be arranged between the side of the display screen 110 and the inner side of the side frame 120, and can be used to bond the display screen 110 and the side frame 120. In another example, the gel assembly 140 can be arranged on the end surface of the middle plate 130 facing the display screen 110, and can be attached to the end surface of the display screen 110 facing the middle plate 130. That is, in this example, the gel assembly 140 is used to bond the display screen 110 and the middle plate 130.

[0064] By arranging the gel assembly 140 between the side frame 120 and the display screen 110, the electronic device 100 can form a relatively sealed cavity to resist the entry of external pollutants into the cavity.

[0065] It should be noted that, Figure 2 The structure of the gel assembly 140 shown is only illustrative, and should not constitute any limitation on the gel assembly 140.

[0066] Generally, the display screen 110 can be bonded together with the middle frame (including the side frame 120 and the middle plate 130). For ease of understanding, the conventional bonding method of the display screen 110 and the middle frame is briefly introduced below.

[0067] The display screen 110 and the middle frame are bonded together by a dispensing process. Taking a conventional dispensing process as an example, the bonding of the display screen 110 and the middle frame is roughly divided into a pretreatment process and a dispensing process. The pretreatment process includes reserving a dispensing platform on the middle frame through structural design; cleaning the surface of the dispensing platform and the bonding surface of the cover plate 112 of the display screen 110 to reduce contaminants, such as chemical cleaning and polishing of the bonding surface. The dispensing process includes preheating the glue in the dispensing machine; controlling the appropriate dispensing path and dispensing amount by an automatic dispensing machine to achieve dispensing. Finally, the display screen 110 and the middle frame are pressed and pressure-maintained to complete the bonding of the two.

[0068] Figure 3 is a front view of an electronic device provided by an embodiment of the present application, as shown in the state where the display screen 110 of the electronic device 100 is lit up, the display screen 110 can be divided into a display area 113 and a black border 114. The black border 114 is located at the edge of the display screen 110 and surrounds the outer periphery of the display area 113. Figure 3

[0069] Generally, the smaller the width of the black border, the larger the area of the region where the electronic device can display content, and the higher the screen-to-body ratio. If the width of the black border is too large, or the width of the black border around the display screen is not uniform, it will affect the appearance of the electronic device, affect the user's experience, and reduce the competitiveness of the electronic product.

[0070] The width of the black border 114 refers to the width between the outer edge of the display area 113 and the outer edge of the cover plate 112, which is mainly composed of the width of the trace area of the display panel 111, the gap between the display panel 111 and the side frame 120, and the width of the dispensing. Some electronic devices reduce the width of the black border by reducing the width of the dispensing, but this will also reduce the contact area between the glue and the display screen 110, which may affect the sealing of the electronic device 100.

[0071] In view of this, the present application provides an electronic device 100 with a narrow black border and good sealing.

[0072] For ease of understanding, an exemplary, Figure 4 a schematic diagram of the structure of a display panel provided by an embodiment of the present application is shown. Among them, Figure 4 (a) of FIG. 1 is a front view of the display panel 111, Figure 4 (b) of FIG. 1 is a front view of the bottom surface of the display panel 111.

[0073] ​In the embodiment of the present application, the front surface of the electronic device 100 or the front surface of the display screen 110 refers to the side facing the user, and the bottom surface of the display screen 110 refers to the side opposite the front surface of the display screen 110. The front surface of the display panel 111 is fixedly connected to the side of the cover plate 112 facing the middle plate 130, and the bottom surface of the display panel 111 is the side of the display panel 111 facing the middle plate 130.

[0074] like Figure 4 As shown in (a) and (b), the display panel 111 may include a display area 1111 and a bending portion 1112. The display area 1111 is the area of ​​the display panel used to display information such as images, text or videos. The bending portion 1112 is connected to the lower short side of the display panel 111 and is the area where the driver integrated circuit chip and the wiring of the display panel 111 are located. Figure 4 (not shown) is located at the edge of the display panel 111, and circuit lines, frame glue, etc. of the display panel 111 can be laid out.

[0075] like Figure 4 As shown in (b), to reduce the width of the black border, the bent portion 1112 can be bent toward the bottom surface of the display panel 111, thereby reducing the width of the black border on the lower short side of the display screen 110. However, compared to the other three sides of the display screen 110, the width of the black border on the lower short side of the display screen 110 is still relatively wide. In addition, due to the minimum trace width limit of the display panel 111 at the rounded corners, the width of the black border at the rounded corners of the display screen 110 is also relatively wide.

[0076] observe Figure 2 The XY cross section of the electronic device 100 can be obtained. Figure 5 FIG. 1 is a schematic diagram of the structure of an electronic device 100 .

[0077] In this embodiment, by designing the structure of the side frame 120 and optimizing the bonding solution between the middle frame and the display screen 110 , the width of the black border around the display screen 110 is reduced and the sealing of the electronic device 100 is ensured.

[0078] The side frame 120 includes a plurality of frames with different structures. Figure 5 The side frame 120 may include a first rounded frame 121 and a non-rounded frame 122 connected to the first rounded frame 121. The first rounded frame 121 and the non-rounded frame 122 have different structures.

[0079] The first rounded-corner frame 121 is a frame including the rounded corners of the side frame 120 , and the non-rounded-corner frame 122 is a frame excluding the rounded corners of the side frame 120 .

[0080] In one example, the side frame 120 can further include a second rounded corner frame 123, wherein one end of the first rounded corner frame 121 and the non-rounded corner frame 122 are connected, and the other end of the non-rounded corner frame 122 and the second rounded corner frame 123 are connected. The first rounded corner frame 121 and the second rounded corner frame 123 have the same structure.

[0081] In some embodiments, the side frame 120 can further include a third rounded corner frame 126, a fourth rounded corner frame 128, a first straight frame 125, a second straight frame 127, and a third straight frame 129. The first straight frame 125 is connected to the second rounded corner frame 123, the third rounded corner frame 126 is connected to the first straight frame 125, the second straight frame 127 is connected to the third rounded corner frame 127, the fourth rounded corner frame 128 is connected to the second straight frame 127, and the third straight frame 129 is connected to the fourth rounded corner frame 128. The third rounded corner frame 126, the fourth rounded corner frame 128, the first straight frame 125, the second straight frame 127, and the third straight frame 129 have the same structure as the first rounded corner frame 121 or the second rounded corner frame 123.

[0082] In some embodiments, the third rounded corner frame 126, the fourth rounded corner frame 128, the first rounded corner frame 121, and the second rounded corner frame 123 have the same structure.

[0083] In the embodiments of the present application, the non-rounded corner frame 122 is located at the lower short side of the side frame 120, the first straight frame 125 and the third straight frame 129 are located at the long side of the side frame 120, and the second straight frame 127 is located at the upper short side of the side frame 120. The structure of the non-rounded corner frame 122 is different from that of the other frames.

[0084] In the embodiments of the present application, the first rounded corner frame 121, the second rounded corner frame 123, the third rounded corner frame 126, and the fourth rounded corner frame 128 can be referred to as the rounded corner frames of the side frame 120.

[0085] Taking the connection of the first rounded corner frame 121 and one end of the non-rounded corner frame 122 as an example, the junction of the first rounded corner frame 121 and the non-rounded corner frame 122 can be located at the tangent position of the rounded corner and the straight side of the side frame 120, or can be located at the straight side of the side frame 120. That is, the plane 124 connecting the first rounded corner frame 121 and the non-rounded corner frame 122 can be located at the tangent position of the rounded corner and the straight side of the side frame 120, or can be located at the straight side of the side frame 120, and the embodiments of the present application do not limit this.

[0086] In one example, the first rounded corner frame 121 can include a rounded corner portion and a straight portion connected to the rounded corner portion, wherein the side of the straight portion of the first rounded corner frame 121 away from the rounded corner portion is connected to the non-rounded corner frame 122.

[0087] In the embodiments of the present application, the side frames 120 adopt different structures, which is beneficial to reduce the width of the black border of the display screen 110 and make the width of the black border of the display screen 110 uniform. For example, in the traditional scheme, the same structure is adopted for the side frames, but the black border of the lower short side of the display panel is wider, and the width of the black border of the other three sides is smaller, so the width of the black border is not uniform. In the present application, different structure designs are adopted at the side frames corresponding to the parts of the display screen with wider black border, so that the width of the black border of the lower short side of the display screen is reduced more, thereby making the width of the black border of the display screen uniform.

[0088] In another aspect, the side frames 120 adopt two different structures, and if the junction of the two structures of the side frames 120 is located at the rounded corners of the side frames 120, the width of the dispensing platform at the rounded corners will be increased, which is not conducive to reducing the width of the black border at the rounded corners of the display screen 110. In the present application, the first rounded corner frame 121 and the non-rounded corner frame 122 are defined, the structure of the non-rounded corner frame 122 is located only at the straight side of the side frame 120, and the junction of the first rounded corner frame 121 and the non-rounded corner frame 122 is located at the straight side of the side frame 120, which is beneficial to reduce the width of the black border at the rounded corners.

[0089] Figure 6 A schematic diagram of the bonding structure at the non-rounded corner frame 122 is shown. Figure 7 is a schematic diagram of a structure of a cover plate provided by an embodiment of the present application.

[0090] As shown in Figure 6 , the non-rounded corner frame 122 can include a first face 1221 facing the display screen 110 and a second face 1222 connected to the first face 1221, the second face 1222 is parallel to the bottom face (i.e. the X-Y face) of the display screen 110, and the angle between the first face 1221 and the second face 1222 is an acute angle. In one example, the angle between the first face 1221 and the second face 1222 is 60 degrees.

[0091] It should be noted that the display screen 110 in the present embodiment can also be a curved screen, that is, the cover plate 112 and the display panel 111 can be curved, and the front face or the bottom face parallel to the front face or the bottom face of the display screen 110 means parallel to the planar part of the front face or the bottom face of the display screen 110.

[0092] Figure 7 is a schematic diagram of a structure of a cover plate provided by an embodiment of the present application. In combination with Figure 6 and Figure 7 , the cover plate 112 can include an inclined side face 1121 and a bottom face 1122. The angle between the inclined side face 1121 and the bottom face 1122 is an acute angle. In one example, the angle between the inclined side face 1121 and the bottom face 1122 is 60 degrees.

[0093] The angle between the first surface 1221 and the second surface 1222 is a first angle, and the angle between the inclined side surface 1121 and the bottom surface 1122 is a second angle. The first angle and the second angle can be equal or not equal, which is not limited in the present application.

[0094] Optionally, the first angle ranges from 30 to 90 degrees, and the second angle ranges from 30 to 90 degrees.

[0095] As shown in Figure 7 , the inclined side surface 1121 of the cover plate 112 can be located at the lower short side of the cover plate 112. The inclined side surface 1121 can be a structure protruding from the main body of the cover plate 112. In one example, the length of the inclined side surface 1121 along the X direction is equal to the length of the non-round corner frame 122 along the X direction.

[0096] The inclined side surface 1121 of the cover plate 112 is attached to the first surface 1221, and the bottom surface 1122 of the cover plate 112 is overlapped with the second surface 1222. The first adhesive 141 covers the first surface 1221 and the second surface 1222, and is in contact with the inclined side surface 1121 and the bottom surface 1122 of the cover plate.

[0097] The first adhesive 141 includes a first part 1411 and a second part 1412. The first part 1411 of the first adhesive 141 is located between the first surface 1221 and the inclined side surface 1121 of the cover plate 112, and the second part 1412 of the first adhesive 141 is located between the second surface 1222 and the bottom surface 1122 of the cover plate 112.

[0098] In the present embodiment, the non-round corner frame 122 actually includes a concave stepped portion, and the second surface 1222 corresponds to the stepped top surface of the concave stepped portion. Since the cover plate 112 includes the inclined side surface 1121, it can cooperate with the concave stepped portion of the non-round corner frame 122, thereby ensuring the glue dispensing width between the cover plate 112 and the non-round corner frame 122, and further ensuring the sealing of the electronic device.

[0099] Please refer to Figure 4 , Figure 5 and Figure 6 . As shown in Figure 6 , the display panel 111 includes a bending portion 1112, and the bending portion 1112 is bent to the bottom surface 1113 of the display panel 111. Among them, the bending portion 1112 has a part attached to the bottom surface 1113 of the display panel 111.

[0100] In one example, the bending portion 1112 and the display panel 111 are two independent structures, and the bending portion 1112 can be connected with the display panel 111.

[0101] Figure 5The position of the bending part 1112 in the electronic device 100 is also shown. Among them, the bending part 1112 is arranged to avoid the first glue filling hole 131 and the second glue filling hole 132.

[0102] The arrangement of the bending part 1112 to avoid the first glue filling hole 131 and the second glue filling hole 132 can be that the orthographic projection of the bending part 1112 along the first direction and the orthographic projection of the first glue filling hole 131 along the first direction do not overlap, and the orthographic projection of the second glue filling hole 132 along the first direction do not overlap.

[0103] Reference Figure 5 The bending part 1112 includes a first part 11121 and a second part 11122. Among them, the first part 11121 is connected with the display area 1111 of the display panel 111, or the first part 11121 can be connected with the wiring area of the edge of the display area 1111. The first part 11121 is located between the first glue filling hole 131 and the second glue filling hole 132.

[0104] In one example, the length of the first part 11121 in the X direction is less than the distance between the two glue filling holes, and the length of the first part 11121 in the Y direction is greater than or equal to the diameter of the glue filling hole.

[0105] In another example, the first part 11121 includes a first inner edge 111211 and a second inner edge 111212, and the second part 11122 includes a first outer edge 111221 and a second outer edge 111222. Among them, the first inner edge 111211, the second inner edge 111212, the first outer edge 111221 and the second outer edge 111222 are perpendicular to the side of the first part 11121 connected with the display panel 111. The distance between the first inner edge 111211 and the second inner edge 111212 is less than the distance between the first glue filling hole 131 and the second glue filling hole 132, and the distance between the first outer edge 111221 and the second outer edge 111222 is greater than the distance between the first glue filling hole 131 and the second glue filling hole 132.

[0106] In some embodiments, the non-round-corner frame 122 corresponds to the first part 11121 of the bending part 1112, and the length of the non-round-corner frame 122 in the X direction is slightly greater than the length of the first part 11121 of the bending part 1112 in the X direction.

[0107] Taking the bonding structure at the first round-corner frame 121 as an example, Figure 8 A schematic diagram of the bonding structure at the first round-corner frame 121 is shown. Please refer to Figure 5 and Figure 8The first rounded frame 121 can include an inner side surface 1211, a stepped portion 1212 protruding from the inner side surface 1211, the stepped portion 1212 including a stepped top surface 12121 and a stepped side surface 12122, the inner side surface 1211 being connected to the stepped top surface 12121, and the stepped side surface 12122 being connected to an edge of the stepped top surface 12121 away from the inner side surface 1211.

[0108] The side surface 1123 of the cover plate 112 is attached to the inner side surface 1211, the bottom surface 1122 of the cover plate 112 is overlapped on the stepped top surface 12121, and the side surface 1114 of the display panel 111 is attached to the stepped side surface 12122. The second adhesive 142 is attached between the rounded frame 122 and the display screen 110, and can be used to connect the rounded frame 122.

[0109] In one example, the second adhesive 142 includes a first portion 1421, a second portion 1422, a third portion 1423, and a fourth portion 1424. The first portion 1421 is connected to the second portion 1422, the second portion 1422 is connected to the third portion 1423, and the third portion 1423 is connected to the fourth portion 1424.

[0110] The first portion 1421 of the second adhesive 142 is arranged between the inner side surface 1211 and the side surface 1123 of the cover plate 112, the second portion 1422 of the second adhesive 142 is arranged between the stepped top surface 12121 and the bottom surface 1122 of the cover plate 112, the third portion 1423 of the second adhesive 142 is arranged between the side surface 1114 of the display panel 111 and the stepped side surface 12122, and the fourth portion 1424 of the second adhesive 142 is arranged between the bottom surface 1113 of the display panel 111 and the middle plate 130.

[0111] In one example, the second adhesive 142 includes a first portion 1421, a second portion 1422, and a third portion 1423. The first portion 1421 is connected to the second portion 1422, and the second portion 1422 is connected to the third portion 1423.

[0112] The first portion 1421 of the second adhesive 142 is arranged between the inner side surface 1211 and the side surface 1123 of the cover plate 112, the second portion 1422 of the second adhesive 142 is arranged between the stepped top surface 12121 and the bottom surface 1122 of the cover plate 112, and the third portion 1423 of the second adhesive 142 is arranged between the side surface 1114 of the display panel 111 and the stepped side surface 12122.

[0113] In another example, the second adhesive 142 includes a first portion 1421 and a second portion 1422. The first portion 1421 is connected to the second portion 1422.

[0114] The first part 1421 of the second glue 142 is arranged between the inner side surface 1211 and the side surface 1123 of the cover plate 112, and the second part 1422 of the second glue 142 is arranged between the step top surface 12121 and the bottom surface 1122 of the cover plate 112.

[0115] In the embodiment, the second glue 142 can be in contact with the side surface 1114 and the bottom surface 1113 of the display panel 111, so that the glue injection path is extended, and the sealing performance of the electronic device 100 is better. In this case, the width of the step 1212 can be reduced, or the step 1212 can be cancelled, so as to leave more space for accommodating the display panel 111, thereby facilitating reduction of the width of the black border of the display screen.

[0116] In the embodiment, the structures of the first rounded frame 121, the second rounded frame 123, the first straight frame 125, the third rounded frame 126, the second straight frame 127, the fourth rounded frame 128, and the third straight frame 129 can be the same, for example, can each include a step portion 1212 protruding from the inner side surface 1211, and the same structure also means the same bonding structure with the display screen 110.

[0117] The second glue 142 can be used to bond any one of the first rounded frame 121, the second rounded frame 123, the first straight frame 125, the third rounded frame 126, the second straight frame 127, the fourth rounded frame 128, and the third straight frame 129 and the display screen 110. The bonding structure at the first rounded frame 121, the second rounded frame 123, the first straight frame 125, the third rounded frame 126, the second straight frame 127, the fourth rounded frame 128, and the third straight frame 129 can refer to the related description of the bonding structure at the first rounded frame 121, and will not be described here.

[0118] Please refer to Figure 5 The first glue injection hole 131 and the second glue injection hole 132 are through holes provided on the middle plate 130 along the first direction. The orthogonal projection of the first glue injection hole 131 and the second glue injection hole 132 along the first direction overlaps the orthogonal projection of the second surface 1222 of the rounded frame 122 along the first direction. The first direction can be a direction along the Z axis, or the first direction can be a direction perpendicular to the bottom surface of the display screen 110, or can also be a direction perpendicular to the bottom surface 1113 of the display panel 111.

[0119] Taking the first glue injection hole 131 as an example, the first glue injection hole 131 is adjacent to the connection between the first rounded frame 121 and the non-rounded frame 122.

[0120] In one example, the orthographic projections of the first glue hole 131 and the step portion 1212 of the first rounded frame 121 along the first direction overlap, wherein the orthographic projection overlap may be that the orthographic projection of the first glue hole 131 and the orthographic projection of the step portion 1212 are connected.

[0121] In another example, the distance between the center of the first glue hole 131 and the connecting plane 124 of the first rounded frame 121 and the non-rounded frame 122 is less than a preset value. The preset value may be the radius of the first glue hole 131. In other words, the first glue hole 131 and the connecting plane 124 should at least be tangent, or the first glue hole 131 and the connecting plane 124 should intersect. It should be understood that the center of the first glue hole 131 is the center of the orthographic projection of the first glue hole 131 on the side of the middle plate 130 facing the display screen 110 (i.e., the XY plane).

[0122] In the embodiment of the present application, the first glue filling hole 131 is located near the connection between the first rounded frame 121 and the non-rounded frame 122, and the third glue 143 can connect the first glue 141 and the second glue 142 through the first glue filling hole 131, thereby ensuring the sealing of the electronic device 100.

[0123] In the embodiment of the present application, the first glue hole 131 and the second glue hole 132 have the same structure. The third glue 143 can also connect the first glue 141 and the second glue 142 through the second glue hole 132, thereby ensuring the sealing of the electronic device 100. In one example, the second glue hole 132 has the same structure as the first glue hole 131 and can also be symmetrically located along the line connecting the centers of the lower short side and the upper short side of the side frame 120.

[0124] Figure 9 FIG. 1 is a schematic diagram of the structure of a colloid assembly 140 provided in an embodiment of the present application. The colloid assembly 140 includes a first colloid 141 , a second colloid 142 , and a third colloid 143 .

[0125] like Figure 9 As shown, the first colloid 141 and the second colloid 142 can be connected end to end or adjacent end to end to roughly form a frame structure. Due to the structural differences between the first rounded frame 121 and the non-rounded frame 122, one end of the first colloid 141 and the end of the second colloid 142 adjacent to the first colloid 141 may be staggered in the Y direction; alternatively, one end of the first colloid 141 and the end of the second colloid 142 adjacent to the first colloid 141 may also partially contact each other. By providing the first and second colloid injection holes 131 and 132 in the Z direction on the middle plate 130 to inject the third colloid 143, the first colloid 141 and the second colloid 142 can be connected to ensure the sealing of the electronic device 100.

[0126] The third glue 143 can be connected between the first glue 141 and the second glue 142. The material of the third glue 143 can be the same as or different from the first glue 141 or the second glue 142. In one example, the viscosity of the third glue 143 can be greater than the viscosity of the first glue 141 or the second glue 142 under a pressurized condition or a temperature-increased condition. The viscosity can be referred to as the viscosity, which can refer to the resistance exhibited by an object to flow.

[0127] One end of the first glue 141 is adjacent to or connected with one end of the second glue 142. The third glue 143 can cover the two ends of the first glue 141 and the second glue 142 adjacent to each other.

[0128] In one example, the first glue 141, the second glue 142, and the third glue 143 use the same glue material, and the glues of the first glue 141, the second glue 142, and the third glue 143 can be fused into one body.

[0129] In another example, the first glue 141, the second glue 142, and the third glue 143 use different glue materials. The third glue 143 has a strong adhesion relationship with the first glue 141 or the second glue 142.

[0130] The shape of the third glue 143 filled through the glue filling hole is not fixed, Figure 9 The projection of the third glue 143 in the Z direction is circular, which is only an example and should not be construed as any limitation.

[0131] In one example, while the third glue 143 connects the first glue 141 and the second glue 142, the third glue 143 is in contact with the cover plate 112, the middle plate 130, and the side frame 120 (including the first rounded corner frame 121 and the non-rounded corner frame 122). In this way, the sealing of the electronic device 100 can be ensured.

[0132] Figure 10 A schematic diagram of an adhesive structure at a glue filling hole is shown. As Figure 10 shown, the first glue filling hole 131 is a through hole provided on the middle plate 130 along a first direction (Z axis) and located at the connection between the first rounded corner frame 121 and the non-rounded corner frame 122. The first direction is perpendicular to the side of the middle plate 130 facing the display screen 110.

[0133] As Figure 10 shown in (a), the orthogonal projection of the first glue filling hole 131 along the first direction is adjacent to or connected with the orthogonal projection of the stepped portion 1212 of the first rounded corner frame 121 along the first direction, and the orthogonal projection of the first glue filling hole 131 along the first direction is adjacent to or connected with the orthogonal projection of the second face 1222 of the non-rounded corner frame 122 along the first direction.

[0134] In some embodiments, the first rounded bezel 121 does not include the step portion 1212. The first glue hole 131 has a projection along the first direction that is adjacent to or connected with a projection along the first direction of the second surface 1222 of the non-rounded bezel 122, and a distance between a center of the first glue hole 131 and a connection plane 124 between the first rounded bezel 121 and the non-rounded bezel 122 is less than a preset value, which can be a radius of the first glue hole 131.

[0135] The connection plane 124 can be understood as an extension plane of an intersection between the first rounded bezel 121 and the non-rounded bezel 122. The connection plane 124 is bounded by the first rounded bezel 121 on one side and the non-rounded bezel 122 on the other side, and the first rounded bezel 121 and the non-rounded bezel 122 have different structures.

[0136] In an example, the first rounded bezel 121 can include a rounded edge portion and a straight edge portion connected to the rounded edge portion, wherein a side of the straight edge portion of the first rounded bezel 121 away from the rounded edge portion is connected to the non-rounded bezel 122.

[0137] The projection along the first direction of the first glue hole 131 is located at an intersection between the straight edge portion of the first rounded bezel 121 and the non-rounded bezel 122. In an example, the projection along the first direction of the first glue hole 131 is connected to the intersection between the straight edge portion of the first rounded bezel 121 and the non-rounded bezel 122.

[0138] From the perspective of the A-A cross section in (a) of Figure 10 the schematic diagram of the bonding structure shown in (b) of Figure 10 .

[0139] As shown in (b) of Figure 10 , the third glue 143 can be in contact with the first glue 141 through the first glue hole 131, and the third glue 143 can be in contact with the cover plate 112, the middle plate 130, and the non-rounded bezel 122.

[0140] In combination with Figure 8 , Figure 9 and Figure 10 , it is not difficult to conclude that the third glue 143 can also be in contact with the second glue 142 through the first glue hole 131.

[0141] In an example, the third glue 143 can be in contact with the first portion 1421, the second portion 1422, the third portion 1423, and the fourth portion 1424 of the second glue 142.

[0142] In some embodiments, Figure 11A schematic view of the bonding structure at the first rounded frame 121 is shown. The first rounded frame 121 can include an inner side surface 1213. The side surface 1123 of the cover plate 112 and the side surface 1114 of the display panel can be located on the same plane or different planes.

[0143] In one example, the second adhesive 142 can include a first portion 1425, a second portion 1426, and a third portion 1427. The first portion 1425 and the second portion 1426 are connected, and the second portion 1426 and the third portion 1427 are connected.

[0144] The first portion 1425 of the second adhesive 142 can be disposed between the inner side surface 1213 and the side surface 1123 of the cover plate 112, the second portion 1426 of the second adhesive 142 can be disposed between the inner side surface 1213 and the side surface 1114 of the display panel 111, and the third portion 1427 of the second adhesive 142 can be disposed between the bottom surface 1113 of the display panel 111 and the middle plate 130.

[0145] In one example, the second adhesive 142 can include a first portion 1425 and a second portion 1426. The first portion 1425 and the second portion 1426 are connected.

[0146] The first portion 1425 of the second adhesive 142 can be disposed between the inner side surface 1213 and the side surface 1123 of the cover plate 112, and the second portion 1426 of the second adhesive 142 can be disposed between the inner side surface 1213 and the side surface 1114 of the display panel 111.

[0147] In one example, the second adhesive 142 can include a first portion 1425, a second portion 1426, and a third portion 1427. The first portion 1425 of the second adhesive 142 can be disposed between the inner side surface 1213 and the side surface 1123 of the cover plate 112, the second portion 1426 of the second adhesive 142 can be disposed between the inner side surface 1213 and the side surface 1114 of the display panel 111, and the third portion 1427 of the second adhesive 142 can be disposed between the edge of the bottom surface 1113 of the display panel 111 and the middle plate 130, and the third portion 1427 of the second adhesive 142 is disposed away from the bending portion 1112.

[0148] In other embodiments, Figure 12 A schematic view of the bonding structure at the first rounded frame 121 is shown. As Figure 12 shown, the side surface 1123 of the cover plate 112 is fitted with the inner side surface 1214 of the first rounded frame 121. Optionally, there is a gap between the side surface 1123 of the cover plate 112 and the inner side surface 1214 of the first rounded frame 121.

[0149] In this embodiment, the display panel 111 may be subjected to a separate waterproofing treatment.

[0150] There is a gap between the side surface 1114 of the display panel 111 and the inner side surface 1214 of the first rounded frame 121 . The second colloid 142 is disposed between the bottom surface 1113 of the display panel 111 and the middle plate 130 .

[0151] The second colloid 142 may be a waterproof adhesive, and is adhered between the bottom surface of the display panel 111 and the middle plate 130 .

[0152] In an example, the second colloid 142 is adhered between the edge of the bottom surface of the display panel 111 and the middle plate 130 , and is disposed away from the bent portion 1112 .

[0153] In the embodiment of the present application, the orthographic projections of the first colloid 141 , the second colloid 142 , and the third colloid 143 along the first direction do not overlap with the orthographic projection of the bent portion 1112 along the first direction.

[0154] For example, Figure 13 FIG2 is a schematic diagram showing the structure of a terminal device 200 provided in an embodiment of the present application. The terminal device 200 may include the structure of the electronic device 100 in the above embodiment.

The processor 210 can be coupled with the audio module 270 through the I2S buses to enable communication between the processor 210 and the audio module 270. The PCM interface can also be used for audio communication, which samples, quantizes, and encodes analog signals. In some embodiments, the audio module 270 and the wireless communication module 260 can be coupled through a PCM bus interface. The UART interface is a general-purpose serial data bus used for asynchronous communication. The bus can be a bidirectional communication bus. It converts data to be transmitted between serial and parallel communication. In some embodiments, the UART interface is commonly used to connect the processor 210 and the wireless communication module 260. The MIPI interface can be used to connect the processor 210 and peripheral devices such as the display 294 and the camera 293. The GPIO interface can be configured by software. The GPIO interface can be configured as a control signal or as a data signal. In some embodiments, the GPIO interface can be used to connect the processor 210 and the camera 293, the display 294, the wireless communication module 260, the audio module 270, the sensor module 280, etc. The USB interface 230 is a USB standard compliant interface, which can be a Mini USB interface, a Micro USB interface, a USB Type C interface, etc. The USB interface 230 can be used to connect a charger to charge the terminal device 200, or to transmit data between the terminal device 200 and a peripheral device.

[0161] It can be understood that the interface connection relationship between the modules shown in the embodiments of the present application is only illustrative and does not constitute a limitation on the structure of the terminal device 200. In some other embodiments of the present application, the terminal device 200 can also use different interface connection modes or a combination of multiple interface connection modes in the above embodiments.
