Display components and electronic devices

Abstract

This disclosure provides a display assembly and an electronic device. The display assembly includes a display screen and a protective adhesive. The display screen includes a display layer, a buffer pad, and a metal foil. The buffer pad connects the back of the display layer and the metal foil, and the edge of the metal foil has a first through-hole. The protective adhesive includes a first part and a second part connected together. The first part wraps around the edges of the display layer, the buffer pad, and the metal foil, and the second part is located within the first through-hole and is fixedly connected to the buffer pad. In this disclosure, since the second part does not come into contact with the silicone-based protective film on the surface of the metal foil, even if the surface of the metal foil is not cleaned before injection molding, a certain degree of adhesion between the injection molding adhesive and the metal foil can be ensured, thereby reducing the molding difficulty of the protective adhesive.

Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display component and electronic device. Background Technology

[0002] In electronic devices such as mobile phones and tablets, a protective adhesive is often formed by low-temperature injection molding at the edge of the display screen. This adhesive then wraps around the display layer to protect it.

[0003] In related technologies, a buffer pad and metal foil are often placed on the back of the display screen to reinforce the display layer. To prevent oxidation of the metal foil surface, a silicone-based protective film is often applied to the outer surface of the metal foil.

[0004] Because the surface of the silicone protective film contains silicone oil, which reduces the adhesion of the injection molding compound, the metal foil needs to be cleaned before the injection molding process to reduce the silicone oil content on the surface of the metal foil, which makes the molding process of the protective compound more complicated. Utility Model Content

[0005] This disclosure provides a display screen assembly and an electronic device, which can solve the aforementioned technical problems existing in the related art. The technical solution is as follows:

[0006] In a first aspect, a display assembly is provided, the display assembly including a display screen and a protective adhesive; the display screen includes a display layer, a buffer pad and a metal foil, the buffer pad connecting the back of the display layer and the metal foil, the edge of the metal foil having a first through hole; the protective adhesive includes a first part and a second part connected together, the first part wrapping the edges of the display layer, the buffer pad and the metal foil, the second part being located in the first through hole and fixedly connected to the buffer pad.

[0007] Thus, during the injection molding process, the injection molding compound enters the first through-hole and solidifies to form the second part of the injection molding compound. The second part passes through the first through-hole and is fixedly connected to the buffer pad, thereby improving the adhesive strength of the protective adhesive. Since the second part does not come into contact with the silicone protective film on the surface of the metal foil, even if the surface of the metal foil is not cleaned before injection molding, the injection molding compound can still have a certain degree of adhesion, thereby reducing the molding difficulty of the protective adhesive.

[0008] In some possible implementations, the buffer pad has a second through hole that communicates with the first through hole; the second part is also located within the second through hole and is fixedly connected to the back of the display layer.

[0009] In this way, the size of the second part can be increased during the injection molding process, thereby increasing the bonding area of ​​the second part and enabling the second part to be fixedly connected to the back of the display layer 12, thereby improving the bonding strength of the second part.

[0010] In some possible implementations, the cushioning pad has countersunk holes that communicate with the first through hole. In this case, the second part is also located within the countersunk holes.

[0011] In this way, the size of the second part can be increased during the injection molding process, thereby increasing the bonding area between the second part and the cushioning pad, and thus improving the bonding strength of the second part.

[0012] In some possible implementations, the cushioning pad has a liquid channel that communicates with the first through-hole; the protective adhesive also includes a third portion located within the liquid channel and connected to the second portion.

[0013] Thus, the third and second parts act like "hooks," hooking the entire protective adhesive onto the surface of the metal foil near the cushioning pad, thereby greatly improving the bonding strength between the protective adhesive and the metal foil. Even without cleaning the surface of the metal foil before injection molding, the injection molding adhesive and the metal foil can still have sufficient adhesion, ensuring the protective effect of the adhesive.

[0014] In some possible implementations, the liquid flow channel extends to the edge of the buffer pad, and the third part is connected to the first part.

[0015] In this way, the final formed third part can be connected to the first and second parts respectively, so that the protective adhesive and the metal foil can form an integrated structure that wraps around each other, thereby ensuring the adhesion between the protective adhesive and the metal foil.

[0016] In some possible implementations, the liquid flow channel extends to the edge of the buffer pad near the first through-hole.

[0017] This avoids excessive length of the liquid flow channel, which could lead to excessive damage to the buffer pad, thus ensuring that the buffer pad has sufficient cushioning effect.

[0018] In some possible implementations, the liquid channel is trough-shaped, and the third part is connected to the back of the metal foil and the display layer, respectively.

[0019] This reduces the difficulty of molding the liquid flow channel and, by connecting the third part to the metal foil and the display layer, improves the bonding strength of the third part.

[0020] In some possible implementations, the axis of the liquid flow channel is a straight line.

[0021] In this way, the third part can fill the entire liquid channel as much as possible, thereby ensuring the adhesive force of the third part and thus ensuring the adhesive effect of the third part.

[0022] In some possible implementations, the cross-section of the liquid flow channel is rectangular.

[0023] Thus, during the partial removal of the buffer pad, the liquid flow channel can be obtained by using a tool to carve grooves in the buffer pad, thereby improving the convenience of liquid flow channel forming.

[0024] In some possible implementations, the cross-sectional area of ​​the liquid flow channel gradually decreases along the direction away from the first through-hole.

[0025] Thus, during the injection molding process, the fluid pressure in the liquid channel gradually increases along the direction away from the first through hole. Even in the part away from the first through hole, the injection molding compound can fill the liquid channel under pressure, thereby ensuring that the molded third part can fill the entire liquid channel, and thus ensuring the adhesion of the third part, so as to ensure the adhesion effect of the third part.

[0026] In some possible implementations, the edge portion of the metal foil has a plurality of first through holes, which are spaced apart circumferentially along the metal foil.

[0027] Thus, by setting multiple first through holes on the metal foil, multiple second parts can be formed to give the liquid adhesive multiple second parts, thereby further improving the adhesive strength of the protective adhesive and ensuring that the injection molding adhesive and the metal foil have a certain adhesive force.

[0028] In a second aspect, an electronic device is provided, which includes a display screen assembly provided in the first aspect and its possible implementations.

[0029] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] This disclosure provides a display screen assembly, such as... Figure 1 As shown, the display assembly includes a display screen 1 and protective adhesive 2. Figure 2 As shown, the display screen 1 includes a display layer 12, a buffer pad 13, and a metal foil 14. The buffer pad 13 connects the back of the display layer 12 and the metal foil 14. The edge of the metal foil 14 has a first through-hole 141. Figure 1 , Figure 2 As shown, the protective adhesive 2 includes a first part 21 and a second part 22 connected together. The first part 21 wraps around the edges of the display layer 12, the buffer pad 13 and the metal foil 14. The second part 22 is located in the first through hole 141 and is fixedly connected to the buffer pad 13.

[0042] Using the display assembly provided in this embodiment, during the injection molding process, the injection molding compound enters the first through-hole 141 and solidifies to form a second portion 22 of the injection molding compound. The second portion 22 passes through the first through-hole 141 and is fixedly connected to the buffer pad 13, thereby improving the adhesive strength of the protective adhesive 2. Since the second portion 22 does not come into contact with the silicone-based protective film on the surface of the metal foil 14, even without cleaning the surface of the metal foil 14 before injection molding, the injection molding compound can still maintain a certain level of adhesion, thus reducing the molding difficulty of the protective adhesive 2.

[0043] like Figure 2As shown, the display screen 1 also includes a cover plate 11, which is fixedly connected to the front of the display layer 12 to protect the display layer 12.

[0044] Optionally, the cover plate 11 is made of transparent glass and is bonded to the front of the display layer 12 by optically transparent adhesive to ensure that the display effect of the display screen 1 is not obstructed.

[0045] Optionally, the buffer pad 13 is a buffer foam, which is mainly used to buffer the display screen 1 when it is subjected to external pressure, so as to reduce the possibility of the display screen 1 being crushed and broken.

[0046] Optionally, the metal foil 14 is copper foil, which is mainly used to support the cushioning foam.

[0047] Optionally, the metal foil 14 is adhered to the back of the cushioning pad 13, which is attached to the back of the display layer 12 with mesh adhesive.

[0048] Combination Figure 1 , Figure 2 As shown, in some possible implementations, the buffer pad 13 has a second through hole 131 that communicates with the first through hole 141. The second portion 22 is also located within the second through hole 131 and is fixedly connected to the back surface of the display layer 12.

[0049] Thus, during the injection molding process, the injection molding compound enters the first through hole 141 and the second through hole 131 in sequence, and solidifies to form the second part 22 of the injection molding compound. The second part 22 is fixedly connected to the inner wall of the first through hole 141, the inner wall of the second through hole 131 and the back of the display layer 12, thereby increasing the size of the second part 22 and thus increasing the bonding area of ​​the second part 22, thereby improving the bonding strength of the second part 22.

[0050] like Figure 5 As shown, in some possible implementations, the buffer pad 13 has a countersunk hole 133, which is understood to be connected to the first through hole 141; the second part 22 is also located inside the countersunk hole.

[0051] In this way, the size of the second part 22 can be increased during the injection molding process, thereby increasing the bonding area between the second part 22 and the buffer pad 13, and improving the bonding strength of the second part 22.

[0052] Figure 3 This is a partial structural diagram of a display screen 1 provided in an embodiment of this disclosure. Figure 4 This is a schematic diagram of part A of the display screen 1.

[0053] Combination Figure 3 , Figure 4As shown, in some possible implementations, the cushioning pad 13 has a liquid channel 132 that communicates with the first through hole 141. The protective adhesive 2 also includes a third portion 23 located within the liquid channel 132 and connected to the second portion 22.

[0054] Thus, during the injection molding process, the injection molding compound enters the first through hole 141 and the liquid flow channel 132 in sequence, and forms a third part 23 in the liquid flow channel 132. The third part 23 can be embedded with the metal foil 14, so that there is sufficient adhesion between the third part 23 and the metal foil 14.

[0055] Furthermore, the third part 23 and the second part 22 can act like "hooks," allowing the entire protective adhesive 2 to hook onto the surface of the metal foil 14 near the buffer pad 13, thereby greatly improving the bonding strength between the protective adhesive 2 and the metal foil 14. Thus, even without cleaning the surface of the metal foil 14 before injection molding, the injection molding compound and the metal foil 14 can be guaranteed to have sufficiently strong adhesion.

[0056] In some possible implementations, the liquid flow channel 132 extends to the edge of the buffer pad 13, and the third part 23 is connected to the first part 21.

[0057] Thus, during the injection molding process, the injection molding compound can flow into the liquid channel 132 from the first through hole 141 and flow from the liquid channel 132 to the edge of the buffer pad 13. The final formed third part 23 can be connected to the first part 21 and the second part 22 respectively, thereby enabling the protective adhesive 2 and the metal foil 14 to form an integrated structure that wraps around each other, which can further improve the adhesion between the protective adhesive 2 and the metal foil 14.

[0058] like Figure 4 As shown, in some possible implementations, the liquid flow channel 132 extends to the edge of the buffer pad 13 near the first through hole 141.

[0059] In this way, the length of the liquid flow channel 132 can be avoided from being too large, which would cause more damage to the buffer pad 13, thus ensuring that the adhesive strength of the protective adhesive 2 is guaranteed while ensuring that the buffer pad 13 has sufficient cushioning effect.

[0060] In some possible implementations, the liquid channel 132 is trough-shaped, and the third part 23 is connected to the back of the metal foil 14 and the display layer 12, respectively.

[0061] Thus, before assembling the buffer 13 and the display layer 12, the liquid flow channel 132 can be directly cut out on the buffer pad 13, thereby reducing the molding difficulty of the liquid flow channel 132. Furthermore, by connecting the third part 23 to the metal foil 14 and the display layer 12, the bonding strength of the third part can be improved.

[0062] like Figure 4 As shown, in some possible implementations, the axis of the liquid flow channel 132 is a straight line.

[0063] In this way, the third part 23 can fill the entire liquid flow channel 132 as much as possible, thereby ensuring that the third part 23 has a sufficiently large adhesive force, and thus ensuring the adhesive effect of the third part 23.

[0064] Optionally, the liquid flow channel 132 has a planar symmetrical structure, and the axis of the liquid flow channel 132 is located on the plane of symmetry.

[0065] like Figure 4 As shown, in some possible implementations, the cross-section of the liquid flow channel 132 is rectangular.

[0066] Thus, during the partial removal of the buffer pad 13, the liquid flow channel 132 can be obtained by using a tool to carve grooves in the buffer pad 13, thereby improving the convenience of forming the liquid flow channel 132.

[0067] In some possible implementations, the cross-sectional area of ​​the liquid flow channel 132 gradually decreases along the direction away from the first through hole 141.

[0068] Thus, during the injection molding process, the fluid pressure in the liquid flow channel 132 gradually increases along the direction away from the first through hole 141. Even in the part away from the first through hole 141, the injection molding compound can fill the liquid flow channel 132 under pressure, thereby ensuring that the molded third part 23 can fill the entire liquid flow channel 132, and thus ensuring the adhesion of the third part 23, so as to ensure the adhesion effect of the third part 23.

[0069] like Figure 3 As shown, in some possible implementations, the edge portion of the metal foil 14 has a plurality of first through holes 141, which are distributed at intervals along the circumference of the metal foil 14.

[0070] Thus, by providing multiple first through holes 141 on the metal foil 14, multiple second parts 22 can be formed in the liquid adhesive, thereby further improving the bonding strength of the protective adhesive 2 through the multiple second parts 22, so as to ensure that the injection molding adhesive and the metal foil 14 have a certain bonding force.

[0071] In the case where the metal foil 14 has multiple first through holes 141 at its edge, if the buffer pad 13 has second through holes 131 but no countersunk holes 133, then the buffer pad 13 has multiple second through holes 131, and each of the multiple second through holes 131 corresponds one-to-one with the multiple first through holes 141. If the buffer pad 13 has countersunk holes 133 but no second through holes 131, then the buffer pad 13 has multiple countersunk holes 133, and each of the multiple countersunk holes 133 corresponds one-to-one with the multiple first through holes 141. If the buffer pad 13 has both multiple countersunk holes 133 and multiple second through holes 131, then the total number of countersunk holes 133 and second through holes 131 corresponds to the total number of first through holes 141.

[0072] Furthermore, if the buffer pad 13 has a liquid flow channel 132, then the buffer pad 13 has multiple liquid flow channels 132, and the multiple liquid flow channels 132 correspond one-to-one with multiple first through holes 141.

[0073] Based on the same concept, this disclosure also provides an electronic device, which includes the display screen assembly provided above.

[0074] Alternatively, the electronic device may be, for example, but not limited to, a smartphone or tablet.
