[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] The embodiment of the present application provides a display device, which can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, etc. Here, in the case where the display device is a mobile phone, the mobile phone can be a foldable mobile phone or a non-foldable mobile phone. The embodiment of the present application does not limit this.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a three-dimensional structure of a display device provided in an embodiment of the present application, Figure 2 yes Figure 1 The display device 000 may include: a housing 100 , a support plate 200 , a display panel 300 , a first adhesive layer 400 , a second adhesive layer 500 , and a third adhesive layer 600 .

[0040] The shell 100 in the display device 000 may include: a supporting portion 101 and a frame portion 102, and the shell 100 in the display device 000 may have a glue injection hole K1 distributed between the frame portion 102 and the supporting portion 101. The frame portion 102 in the shell 100 refers to a portion of the shell 100 close to the edge. For example, the frame portion 102 may be a portion distributed at the outer edge of the shell 100. For this purpose, the frame portion 102 may generally be annular. The supporting portion 101 in the shell 100 refers to a portion enclosed in an area surrounded by the frame portion 102. Here, the supporting portion 101 and the frame portion 102 in the shell 100 may be fixedly connected, and the supporting portion 101 and the frame portion 102 in the shell 100 are an integral part, and the two may be formed simultaneously by the same process.

[0041] The support plate 200 in the display device 000 may be located on the support portion 101 in the housing 100 , and the support plate 200 in the display device 000 and the support portion 101 in the housing 100 may be bonded together via a first adhesive layer 400 .

[0042] The display panel 300 in the display device 000 is distributed on the side of the support plate 200 facing away from the shell 100, and the display panel 300 in the display device 000 can be bonded to the side of the support plate 200 facing away from the supporting part 101 of the shell 100 through the second adhesive layer 500, and the display panel 300 in the display device 000 is also bonded to the frame part 102 of the shell 100 through the third adhesive layer 600.

[0043] For examples, please refer to Figure 3 , Figure 3 3 is a partial cross-sectional schematic diagram of a display device provided in an embodiment of the present application. The display panel 300 may include: a flat portion 301 and a bent portion 302, and one side of the flat portion 301 is connected to one end of the bent portion 302. In this case, the side of the bent portion 302 of the display panel 300 that is away from the flat portion 301 may be connected to the support plate 200 through the second adhesive layer 500, and the other side of the flat portion 301 of the display panel 300 that is not connected to the bent portion 302 may be bonded to the frame portion 102 through the third adhesive layer 600.

[0044] It should be noted that the first adhesive layer 400, the second adhesive layer 500 and the third adhesive layer 600 in the display device 000 refer to colloids that have a bonding and sealing function, and may be foam glue or colloids obtained by curing glue. This embodiment of the application does not limit this.

[0045] In a possible implementation, the frame portion 102 in the housing 100 may include: two first frames arranged opposite to each other and two second frames arranged opposite to each other. The support portion 101 in the housing 100 may be fixedly connected to one of the two second frames. In this case, the display panel 300 needs to be fixedly connected to the two first frames in the frame portion 102 and the other of the two second frames through the third adhesive layer 600.

[0046] For example, assuming that the two first frames are the left and right frames, the two second frames are the upper and lower frames, and the support portion 101 needs to be fixedly connected to the lower frame, then the lower side of the display panel 300 can be fixed to the support plate 200 bonded to the support portion 101 through the second adhesive layer 500, and the left side, upper side and right side of the display panel 300 can be fixed to the left frame, upper frame and right frame respectively through the third adhesive layer 500.

[0047] It should be noted that, since the lower side of the display panel 300 needs to be first fixed to the support plate 200 through the second adhesive layer 500, and then the support plate 200 is fixed to the support portion 101 in the housing 100 through the first adhesive layer 400, and the other side of the display panel 300 can be directly fixed to the frame portion 102 in the housing 100 through the third adhesive layer 600. Therefore, there is usually an area that cannot be covered by the colloid between the end of the left frame facing the lower frame and the support portion 101, and between the end of the right frame facing the lower frame and the support portion 101. For this reason, the adhesive colloid between the display panel 300 and the housing 100 cannot play a sealing role for the display device.

[0048] In this case, two glue holes K1 need to be set on the shell 100, one of which can be distributed between the end of the left frame facing the lower frame and the supporting part 101, and the other glue hole K1 can be distributed between the end of the right frame facing the lower frame and the supporting part 101.

[0049] For example, please refer to Figure 4 , Figure 4 1 is a schematic top view of an adhesive layer between a display panel and a housing provided in an embodiment of the present application. The glue injection hole K1 provided on the housing 100 is used to inject the sealant A1 so that the sealant A1 is respectively bonded to the first adhesive layer 400, the second adhesive layer 500 and the third adhesive layer 600 in the display device 000. It should be noted that when two glue injection holes K1 are provided on the housing 100, the sealant A1 can be injected into each glue injection hole K1.

[0050] In the embodiment of the present application, the sealant A1 refers to a sealant that can be reliably bonded to the first adhesive layer 400, the second adhesive layer 500 and the third adhesive layer 600 in the display device 000, and the sealant A1 can be connected to the first adhesive layer 400, the second adhesive layer 500 and the third adhesive layer 600 as a whole after curing. In this way, by injecting the sealant A1 into the glue injection hole K1 set on the shell 100, and after the sealant A1 is respectively bonded to the first adhesive layer 400, the second adhesive layer 500 and the third adhesive layer 600, it can be ensured that a complete annular sealant can be formed between the display panel 300 and the shell 100, and this annular sealant can not only achieve the bonding between the display panel 300 and the shell 100, but also achieve the sealing of the display device 000, thereby effectively reducing the probability of water vapor and dust in the external environment entering the interior of the display device 000, so that the display device has good sealing and reliability.

[0051] For example, during the assembly process of the display device 000, first, the support plate 200 in the display device 000 is fixed to the support portion 101 of the shell 100 through the first adhesive layer 400 (for example, the support plate can be bonded to the support portion of the shell by glue, or by foam glue). Then, the display panel 300 is connected to the shell 100 to which the support plate 200 is fixed (for example, the display panel can be bonded to the support portion of the shell by glue, or by foam glue). That is, the support plate 200 in the shell 100 is connected to the display panel 300 through the second adhesive layer 500, and the portion of the display panel 300 not covered by the support plate 200 is connected to the frame portion 102 in the shell 100 through the third adhesive layer 600. Finally, the sealant A1 is injected through the injection hole K1 in the housing 100 to bond the first adhesive layer 400 , the second adhesive layer 500 and the third adhesive layer 600 , thereby forming an annular sealant between the display panel 300 of the display device 000 and the housing 100 .

[0052] In summary, the embodiment of the present application provides a display device, which may include: a housing, a support plate, a display panel, a first adhesive layer, a second adhesive layer, and a third adhesive layer. By injecting sealant into the glue injection hole set on the housing, and after the sealant is respectively bonded to the first adhesive layer, the second adhesive layer, and the third adhesive layer, it can be ensured that a complete annular sealing colloid can be formed between the display panel and the housing. This annular sealing colloid can not only achieve bonding between the display panel and the housing, but also achieve sealing of the display device, thereby effectively reducing the probability of water vapor and dust in the external environment entering the interior of the display device, so that the display device has good sealing and reliability.

[0053] In the examples of this application, please refer to Figure 5 , Figure 5 yes Figure 2 Schematic diagram of the three-dimensional structure of the housing in the display device 000. The support portion 101 of the housing 100 in the display device 000 may have a first groove 101a for accommodating the first adhesive layer 400 of the display device 000 on the side facing the display panel 300 in the display device 000. The frame portion 102 of the housing 100 may have a second groove 102a for accommodating the third adhesive layer 600 on the side facing the display panel 300 in the display device 000.

[0054] Here, when glue is applied to the supporting part 101 of the shell 100 in the display device 000, the liquid glue can gather in the first groove 101a of the supporting part 101 and form a certain thickness. After it is solidified, a first adhesive layer 400 with good sealing and bonding ability can be obtained, so that the supporting plate 200 and the supporting part 101 of the shell 100 can be stably bonded, and it can be ensured that water vapor in the external environment is not easy to invade the interior of the display device 000 from between the supporting plate 200 and the supporting part 101. Similarly, when glue is applied to the frame portion 102 of the shell 100 in the display device 000, the liquid glue can gather in the second groove 102a of the frame portion 102 and form a certain thickness. After it is solidified, a third adhesive layer 600 with good sealing and bonding ability can be obtained, so that the support plate 200 and the frame portion 102 of the shell 100 can be stably bonded, and it can be ensured that water vapor in the external environment is not easy to invade the interior of the display device 000 from between the support plate 200 and the frame portion 102.

[0055] It should be noted that, since the side of the support plate 200 away from the support portion 101 needs to be bonded to the bending portion 302 in the display panel 300 through the second adhesive layer 500, and the bending portion 302 usually needs to be bound with a driver chip for driving the display panel 300 to display a picture. Therefore, in order to ensure that the stability of the bending portion 302 is high, a second adhesive layer 500 with a buffering property can be used. For example, the second adhesive layer 500 can be a foam glue, and the sealing property of the foam glue is also good. For this reason, water vapor in the external environment is not easy to invade the interior of the display device 000 from between the support plate 200 and the display panel 300.

[0056] In the present application, the glue injection holes K1 provided on the housing 100 are distributed between the first groove 101a on the support part 101 of the housing 100 and the second groove 102a on the frame part 102. Since there is a portion of the support plate 200 between the display panel 300 and the housing 100 in the display device 000, the display panel 300 is connected to the housing 100 through the support plate 200, and there is no portion of the support plate 200 between the display panel 300 and the housing 100, and the display panel 300 is directly connected to the housing 100. Therefore, there is a height difference between the first groove 101a and the second groove 102a on the same housing 100, which results in a height difference between the first adhesive layer 400 and the second adhesive layer 500 in the display device 000. The glue injection hole K1 is set between the first groove body 101a and the second groove body 102a, and the sealant A1 is injected through the glue injection hole K1, so that the first adhesive layer 400 and the second adhesive layer 500 in the display device 000 can be reliably connected to form an annular sealant between the display panel 300 and the housing 100.

[0057] Optional, please refer to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of a first adhesive layer and a housing of a display device provided in an embodiment of the present application, Figure 7 yes Figure 6 A partial enlarged view of point C in the middle. The first adhesive layer 400 in the display device 000 may have a first hollow gap K2 on the side facing the glue filling hole K1. The display device 000 may also include: a glue dispensing portion A2 located in the first hollow gap K2 of the first adhesive layer 400. Among them, the glue dispensing portion A2 can be bonded to the first adhesive layer 400 in the first hollow gap K2, and can be bonded to the side wall of the first groove body 101a of the supporting part 101 in the shell 100, and the glue dispensing portion A2 can also be bonded to the sealant A1. That is, the sealant A1 injected from the glue filling hole K1 can be bonded to the first adhesive layer 400 through the glue dispensing portion A2 set at the first hollow gap K2.

[0058] In this case, even if the first adhesive layer 400 located in the first tank body 101a cannot be fully bonded to the inner wall of the first tank body 101a, resulting in a gap between the first adhesive layer 400 and the inner wall of the first tank body 101a that allows water vapor to penetrate, a first hollow notch K2 can be provided on the side of the first adhesive layer 400 facing the glue injection hole K1, and a glue spot A2 is additionally provided in the first hollow notch K2 to bond to the first adhesive layer 400 and the inner wall of the first tank body 101a, so that the glue spot A2 can block the water vapor that penetrates from the gap between the first adhesive layer 400 and the inner wall of the first tank body 101a. In this way, the probability of water vapor in the external environment penetrating into the interior of the display device 000 from between the support plate 200 and the support portion 101 can be further reduced.

[0059] In the embodiment of the present application, after the first adhesive layer 400 is formed in the first groove 101a of the support part 101, it is usually necessary to firstly arrange the support plate 200 on the support part 101 to complete the assembly between the support plate 200 and the support part 101. Afterwards, the glue dispensing part A2 is formed in the first hollow notch K2 of the first adhesive layer 400 by a glue dispensing process.

[0060] Here, in order not to affect the normal formation of the glue dispensing portion A2 in the first hollow gap K2, please refer to Figure 8 , Figure 8is a schematic diagram of a support plate and a shell of a display device provided in an embodiment of the present application. It is necessary to set a second hollow notch K3 connected to the first hollow notch K2 in the support plate 200 in the display device 000. Here, the orthographic projection of the first hollow notch K2 on the display surface of the display panel 300 is located within the orthographic projection of the second hollow notch K3 on the display surface of the display panel 300. In this way, it can be ensured that the opening area of ​​the second hollow notch K3 set on the support plate 200 is at least larger than the opening area of ​​the first hollow notch K2, so as to ensure that the support plate 200 will not block the first hollow notch K2 of the first adhesive layer 200. To this end, after the assembly between the support plate 200 and the support part 101 is realized by the first adhesive layer 200, the glue dispensing part A2 can be formed in the first hollow notch K2 of the first adhesive layer 400 by the glue dispensing process, and it can be ensured that the formed glue dispensing part A2 can be respectively bonded to the first adhesive layer 200 and the side wall of the first trough body 101a.

[0061] Optional, please refer to Fig. 9 , Fig. 9 Schematic diagram of a second adhesive layer and a housing of a display device provided in an embodiment of the present application. The second adhesive layer 500 in the display device 000 has a third hollow notch K4 connected to the second hollow notch K3 on the support plate 200, and the orthographic projection of the second hollow notch K3 of the support plate 200 on the display surface of the display panel 300 can be located within the orthographic projection of the third hollow notch K4 on the display surface of the display panel 100.

[0062] In this case, since the glue spot A2 formed in the first hollow notch K2 has a certain thickness, the glue spot A2 may protrude from the side of the support plate 200 away from the support portion 101 of the housing 100. Therefore, after the third hollow notch K4 connected to the second hollow notch K3 is provided on the second adhesive layer 500, even if the glue spot A2 protrudes from the side of the support plate 200 away from the support portion 101 of the housing 100, it can be ensured that the part of the glue spot A2 protruding from the support plate 200 is located in the third hollow notch K4, so as to ensure that the part of the glue spot A2 protruding from the support plate 200 does not squeeze the second adhesive layer 200, so as to ensure that the second adhesive layer 200 can better buffer the bent portion 302 in the display panel 300.

[0063] In the embodiment of the present application, the distance between the side of the second adhesive layer 500 in the display device 000 that faces away from the support plate 200 and the bottom surface of the first groove body 101a of the support portion 101 may be greater than or equal to the thickness of the glue-dispensing portion A2 in the direction perpendicular to the display surface of the display panel 300. In this case, it can be ensured that the glue-dispensing portion A2 will not protrude from the second adhesive layer 500 as a whole in the direction perpendicular to the display surface of the display panel 300, so as to ensure that the glue-dispensing portion A2 only contacts the bent portion 302 in the display panel 300 at most, and will not apply a force to the bent portion 302, thereby ensuring that the stability of the bent portion 302 in the display panel 300 is high.

[0064] Optionally, the sealant A1 injected through the injection hole K1 can be bonded to the second adhesive layer 500 in the third hollow opening K4 of the second adhesive layer 500. In this case, the sealant A1 enters the third hollow opening K4 and can be in good contact with the second adhesive layer 500, thereby improving the sealing performance of the display device 000.

[0065] In this application, please refer to Fig.10 , Fig.10 1 is a schematic diagram of a three-dimensional structure of a housing of a display device provided in an embodiment of the present application. The supporting portion 101 of the housing 100 in the display device 000 may have a hollow groove 101b.

[0066] Please refer to Fig.11 , Fig.11 2 is a schematic diagram of a three-dimensional structure of a support plate and a housing of a display device provided in an embodiment of the present application. The support plate 200 in the display device 000 can cover the hollow groove 101b to form a battery compartment with the hollow groove 101b; and, please refer to Fig.12 , Fig.12 yes Figure 2 The first adhesive layer 400 of the display device 000 may include: a ring-shaped portion 401 ( Fig.11 In this case, the support plate 200 in the display device 000 is connected to the support portion 101 of the housing 100 through the annular portion of the first adhesive layer 400, and the support plate 200 in the display device 000 and the hollow groove 101b of the support portion 101 can form a well-sealed battery compartment, thereby ensuring that moisture and dust do not enter the battery compartment.

[0067] In the examples of this application, please refer to Fig.12, the first adhesive layer 400 in the display device 000 may further include: a strip portion 402 connected to the annular portion 401 on the first adhesive layer 400, and the end of the strip portion 402 away from the annular portion 401 is bonded to the sealant A1. In this case, the strip portion 402 on the first adhesive layer 400 can be used to connect the support plate 200 with the support portion 101 of the housing 100, and the strip portion 402 on the first adhesive layer 400 is bonded to the sealant A1 to improve the sealing performance of the display device 000.

[0068] In the embodiment of the present application, the sealant A1 can be a solid colloid formed by a glue dispensing process. The glue dispensing process is also called glue application, glue coating, glue pouring, glue dripping, etc., which refers to applying, pouring or dripping glue onto the product to allow the product to play the role of bonding, potting, fixing, etc. In this way, when the sealant A1 is injected through the glue pouring hole K1, since the sealant A1 is in liquid state during use, it can fill the gap between the first adhesive layer 400, the second adhesive layer 500 and the third adhesive layer 600 in the display device 000, and after curing, it can be reliably bonded to the first adhesive layer 400, the second adhesive layer 500 and the third adhesive layer 600 in the display device 000 to form a whole.

[0069] In summary, the embodiment of the present application provides a display device, which may include: a housing, a support plate, a display panel, a first adhesive layer, a second adhesive layer, and a third adhesive layer. By injecting sealant into the glue injection hole set on the housing, and after the sealant is respectively bonded to the first adhesive layer, the second adhesive layer, and the third adhesive layer, it can be ensured that a complete annular sealing colloid can be formed between the display panel and the housing. This annular sealing colloid can not only achieve bonding between the display panel and the housing, but also achieve sealing of the display device, thereby effectively reducing the probability of water vapor and dust in the external environment entering the interior of the display device, so that the display device has good sealing and reliability.
