Detailed implementation manners

[0040] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings.

[0041] An embodiment of the present application provides a display screen assembly, which can be applied to various terminals with display functions, such as mobile phones, tablet computers, televisions, monitors, laptop computers, etc.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a three-dimensional structure schematic diagram of a terminal provided by an embodiment of the present application, Figure 2 is Figure 1 an exploded view of the display screen assembly in the provided terminal, Figure 3 is Figure 1 a schematic diagram of a cross-sectional structure of a provided terminal ( Figure 3 can be Figure 1 a schematic diagram of the cross-sectional structure of the provided terminal at B1-B1), and the display screen assembly 10 includes: a display module 11, a screen bracket 12, a first sealing layer 13, and a second sealing layer 14.

[0043] The display module 11 has a display surface F1 and a back surface F2 opposite to the display surface F1. Here, the display module 11 is used to display images and texts. Exemplarily, the display module 11 provided in the embodiments of the present application may be an Organic Light Emitting Diode (OLED) display module. The OLED display module has flexibility and a finer display effect, and can be widely applied to various electronic products.

[0044] The screen support 12 is located on the back surface F2 of the display module 11, and the screen support 12 has a first connection hole A1. Here, the screen support 12 is used to support the display module 11, and it is easier to set the first connection hole A1 on the screen support 2, so that the disassembly function can be facilitated.

[0045] The first sealing layer 13 is located between the display module 11 and the screen support 12, and the first sealing layer 13 is respectively connected to the back surface F2 of the display module 11 and the screen support 12. Here, the first sealing layer 13 can be annular, and the first sealing layer 13 can be connected to the edge area of the back surface F2 of the display module 11, so that the first sealing layer 13 can achieve a sealing effect between the back surface F2 of the display module 11 and the screen support 12, thereby effectively reducing the probability of moisture and dust in the external environment entering from the edge area. The first sealing layer 13 can also include a material with adhesiveness to achieve an adhesive effect, so that the structural stability between the display module 11 and the screen support 12 is better.

[0046] The second sealing layer 14 is connected to the side of the screen support 12 facing away from the display module 11, and the first connection hole A1 is located within the area surrounded by the second sealing layer 14. The second sealing layer 14 is used to abut against the housing 21 so that the first connection hole A1 communicates with the second connection hole A2 of the housing 21.

[0047] Here, the second sealing layer 14 can be annular, and the second sealing layer 14 can be connected to the edge area of the screen support 12. During the assembly process of the display screen assembly 10 and the housing 21, the second sealing layer 14 is fixedly connected to the screen support 12, and the second sealing layer 14 abuts against the housing 21. Thus, the second sealing layer 14 can achieve a sealing effect, and the first connection hole A1 and the second connection hole A2 can be connected by a connecting member 23, which can further ensure the sealing effect of the second sealing layer 14. During the disassembly process of the display screen assembly 10 and the housing 21, the second sealing layer 14 is not fixedly connected to the housing 21, and the connecting member 23 can be taken out from the first connection hole A1 and the second connection hole A2, so that the display screen assembly 10 can be integrally disassembled from the housing 21. Therefore, the display screen assembly 10 provided in the embodiments of the present application can achieve the function of convenient disassembly on the basis of ensuring the waterproof effect.

[0048] In summary, an embodiment of the present application provides a display screen assembly. Among them, a screen bracket is provided on the back of the display module, and the display module and the screen bracket are connected by a first sealing layer, so that the display module and the screen bracket can achieve a sealing and waterproof effect. A second sealing layer is provided on the side of the screen bracket away from the display module and connected to the screen bracket. Therefore, when the display screen assembly is assembled with the shell, the second sealing layer can abut against the shell to achieve a sealing and waterproof effect. In addition, the first connecting hole of the screen bracket is connected to the second connecting hole of the shell, so that the connected first connecting hole and the second connecting hole can be connected by a connecting member, thereby improving the simplicity of assembly and disassembly of the display screen assembly and the shell, and will not damage the waterproofness of the terminal during disassembly.

[0049] In the embodiment of the present application, the first sealing layer is used to achieve sealing between the display module and the screen bracket. The structure of the first sealing layer is described below:

[0050] Please refer to Figure 4 , Figure 4 It is an exploded view of another display screen assembly provided in an embodiment of the present application. The first sealing layer 13 includes: a first adhesive layer 131, a second adhesive layer 132 and a sealant 133. The first adhesive layer 131, the second adhesive layer 132 and the sealant 133 can be a colloid that plays a sealing and bonding role, and the colloid can include at least one of a foam glue and a waterproof glue. Exemplarily, the first adhesive layer 131 can be a foam glue, and the foam glue has good energy absorption, shock absorption and buffering properties. Therefore, the first adhesive layer 131 uses foam glue and can also play a buffering role in the bonding process. The second adhesive layer 132 and the sealant 133 can be waterproof glue, and the waterproof glue refers to a colloid obtained after the liquid waterproof glue is cured.

[0051] The screen bracket 12 has: two first frames D1 and two second frames D2 arranged opposite to each other. The display module 11 is bonded to the two first frames D1 and one of the two second frames D2 through a first adhesive layer 131, and the display module 11 is bonded to the other of the two second frames D2 through a second adhesive layer 132. The sealant 133 is bonded to the first adhesive layer 131 and the second adhesive layer 132 respectively.

[0052] Exemplarily, the two first side frames D1 can be the left and right side frames respectively, and the two second side frames D2 can be the upper and lower side frames respectively. In this way, the upper edge, left edge, and right edge of the display module 11 can be fixed to the upper side frame and the left and right side frames of the screen support 12 through the first adhesive layer 131 respectively. The lower edge of the display module 11 can be fixed to the lower side frame of the screen support 12 through the second adhesive layer 132. Since there may be a gap between the first adhesive layer 131 and the second adhesive layer 132, the sealant 133 can be used to fill this gap and bond the first adhesive layer 131 and the second adhesive layer 132 together to form an annular first sealing layer 13. In this way, the sealing performance of the first sealing layer 13 can be ensured, and thus the effect of sealing and waterproofing can be achieved between the display module 11 and the screen support 12.

[0053] In the embodiment of the present application, the second sealing layer is used to achieve the seal between the screen support and the housing. The structure of the second sealing layer will be described below:

[0054] Please refer to Figure 5 , Figure 5 is Figure 1 another schematic cross-sectional structure diagram of the terminal provided by Figure 5 which can be Figure 1 the schematic cross-sectional structure diagram of the terminal provided by

[0055] In the present application, the first sealing layer can include various structures. For an exemplary embodiment, please refer to Figure 5 and Figure 6 , Figure 6 is Figure 5 the schematic structure diagram of part of the structures in the display screen assembly provided by

[0056] Among them, the sealing layer body 141 can enhance the connection strength between the screen bracket 12 and the first sealing layer 13. The second sealing layer 14 can be a sealing silica gel ring, that is, the second sealing layer 14 has elasticity. During the assembly process of the display screen assembly 10 and the housing 21, the convex structure 142 abuts against the housing 21, and the convex structure 142 can be compressed and deformed, so as to improve the sealing performance between the display screen assembly 10 and the housing 21.

[0057] Optionally, the convex structure 142 is annular. In the first direction X, the convex structure 142 has a first side surface S1 and a second side surface S2 which are oppositely arranged. The first side surface S1 is closer to the outer edge of the screen bracket 12 than the second side surface S2. The first direction X is parallel to the display surface F1 and perpendicular to the extending direction of the convex structure 132.

[0058] Among them, the included angle α1 between the first side surface S1 and the surface of the sealing layer body 141 facing away from the screen bracket 12 is an acute angle. In this way, during the assembly process of the display screen assembly 10 and the housing 21, after the convex structure 142 is compressed and deformed, the first side surface S1 still biases towards the outer edge of the screen bracket 12. On the one hand, it can prevent a gap from existing between the convex structure 142 and the housing 21 after deformation, so as to effectively block water vapor and dust in the external environment. On the other hand, it can reduce the force of the convex structure 142 on the main housing 21, so as to improve the connection strength between the assembled display screen assembly 10 and the housing 21.

[0059] Optionally, the included angle α2 between the second side surface S2 and the surface of the sealing layer body 141 facing away from the screen bracket 12 is an obtuse angle. In this way, the convex structure 142 of this shape is more easily compressed and deformed, so as to facilitate the abutment of the convex structure 142 against the housing 21 to ensure the waterproof effect. In addition, the included angle α2 can also be a right angle or an acute angle.

[0060] In addition, both the sealing layer body 141 and the corresponding groove 121 are annular, so that water vapor and dust in the external environment can be blocked outside the second sealing layer 14, thereby improving the waterproof performance.

[0061] The second sealing layer provided by the embodiment of the present application can also be reused as a light guide column at the light sensing hole. Please refer to Figure 7 and Figure 8 , Figure 7 which Figure 1 is a schematic enlarged structure diagram of a terminal provided by Figure 7 which may be Figure 1 a schematic enlarged structure diagram of the Q1 area of the terminal provided by Figure 8 which Figure 7 is a schematic cross-sectional structure diagram of a display screen assembly provided by Figure 8 which may be Figure 7Schematic cross-sectional structure diagram of the provided display screen component at B2-B2). The edge area of the display module 11 has a light sensing hole H.

[0062] The light transmittance at the light sensing hole H is relatively high, so that the ambient light from the outside can pass through the light sensing hole H. In addition, a light guide column and a sensor are equipped in the terminal, so that the light passing through the light sensing hole H can be further guided by the light guide column and transmitted to the sensor. The light sensing hole H may include a receiving hole H1 and a transmitting hole H2. The light sensor may be correspondingly arranged with the receiving hole H1, so that the light sensor can sense the brightness of the ambient light, thereby automatically adjusting the brightness of the display module 11. The distance sensor may be correspondingly arranged with the transmitting hole H2, so that the distance sensor can sense the operating distance of the user by emitting and receiving light, thereby automatically turning off the screen. In addition, the receiving hole H1 and the transmitting hole H2 may also be integrated into one hole, and the embodiments of the present application do not limit this.

[0063] The screen support 12 has a first opening 122 communicating with the groove 121. The opening surface of the first opening 122 facing away from the groove 121 faces the display module 11, and the orthographic projection of the first opening 122 on the display module 11 covers the light sensing hole H. That is, in the direction perpendicular to the display module 11, the groove 121 and the first opening 122 can penetrate the screen support 12.

[0064] The second sealing layer 14 further includes: a filling portion 143 connected to the side of the sealing layer body 141 facing away from the convex structure 142. The filling portion 143 has light transmittance, and at least part of the filling portion 143 is located in the first opening 122. That is, the orthographic projection of the filling portion 143 on the display module 11 also covers the light sensing hole H.

[0065] It should be noted that the second sealing layer 14 is an integral structure, that is, the sealing layer body 141, the convex structure 142, and the filling portion 143 all have light transmittance. Exemplarily, the second sealing layer 14 may include a transparent silicone material. In this way, the ambient light from the outside can further pass through the second sealing layer 14 after passing through the light sensing hole H, so that the second sealing layer 14 can achieve a light guiding effect, thereby eliminating the need to separately provide a light guide column and achieving the effect of simplifying the structure.

[0066] Optionally, the display module 11 includes: a cover plate 111 and a display panel 112. The cover plate 111 is connected to the light-emitting side of the display panel 112, and the portion of the cover plate 111 protruding relative to the display panel 112 has a light sensing hole H. The display panel is used to implement the display function. Exemplarily, the display panel may be an OLED display panel. The cover plate 111 is used to protect the display panel 112 on the light-emitting side. Exemplarily, the cover plate 111 may be a glass cover plate. The light sensing hole H can be obtained by coating ink with a relatively high light transmittance at a specified position on the cover plate 111 by screen printing.

[0067] A part of the filling portion 143 is located within the first opening 122, and another part of the filling portion 143 extends outside the first opening 122 and abuts against the cover plate 111 at the position where the light sensing hole H is located. In this way, the other part of the filling portion 143 can further ensure the waterproof effect at the light sensing hole H.

[0068] In summary, the embodiment of the present application provides a display screen assembly. Among them, a screen support is provided on the back of the display module, and the display module and the screen support are connected through a first sealing layer, so that the sealing and waterproof effect can be ensured between the display module and the screen support. A second sealing layer is provided and connected to the screen support on the side of the screen support facing away from the display module. Therefore, when the display screen assembly is assembled with the housing, the second sealing layer can abut against the housing to achieve the sealing and waterproof effect. And, the first connection hole of the screen support communicates with the second connection hole of the housing, so that the connected first connection hole and second connection hole can be connected through a connecting piece, thereby improving the simplicity of the assembly and disassembly of the display screen assembly and the housing, and the waterproof property of the terminal will not be damaged during disassembly.

[0069] On the other hand, the embodiment of the present application provides a terminal, please refer to Figure 1 and Figure 5 , the terminal 20 includes: a housing 21, a connecting piece 23, and a display screen assembly 10, and the display screen assembly 10 is the display screen assembly 10 of any of the above embodiments.

[0070] Among them, the housing 21 has a second connection hole A2, the second connection hole A2 communicates with the first connection hole A1 in the display screen assembly 10, and the connecting piece 23 is connected to the connected first connection hole A1 and second connection hole A2, so that the assembly of the display screen assembly 10 and the housing 21 can be realized. During the disassembly process, the user can disassemble the display screen assembly 10 by disassembling the connecting piece 23 without disassembling other components inside the terminal 20, such as components like the battery, main board, flexible circuit board, etc., thereby achieving the effect of quickly disassembling and repairing the display screen assembly 10. Exemplarily, the connecting piece 23 can be a screw.

[0071] Optionally, please refer to Figure 4 and Figure 5 , the terminal 20 further includes: a receiver assembly (not shown in the figure) assembled in the housing 21. The receiver assembly is used to receive an audio electrical signal and convert it into a sound signal to achieve audio playback. The receiver assembly provided in the embodiment of the present application can also be a waterproof device, so that the terminal 12 as a whole can achieve a waterproof effect.

[0072] At the edge position of the screen support 12, there is a first avoidance groove C1 that cooperates with the receiver assembly, and a part of the receiver assembly is located within the first avoidance groove C1. In this way, the first avoidance groove C1 can be used to avoid the receiver assembly, thereby preventing the screen support 12 from affecting the sound effect of the receiver assembly.

[0073] The second sealing layer 14 includes: a first sealing section L1 and a second sealing section L2. The two ends of the first sealing section L1 are fixedly connected to the two ends of the second sealing section L2 respectively. The first sealing section L1 is connected to the outer edge of the screen support 12. The second sealing section L2 can extend into the area surrounded by the first sealing section L1, and the second sealing section L2 is distributed around the first avoidance groove C1. In this way, the second sealing section L2 is only distributed around the left and right edges and the lower edge of the receiver assembly, so that the receiver assembly can normally emit sound from above, thereby avoiding the second sealing layer 14 from affecting the sound effect of the receiver assembly.

[0074] The screen assembly 12 may also have multiple avoidance grooves other than the first avoidance groove C1. For example, a second avoidance groove C2 for cooperating with the power supply assembly, a third avoidance groove C3 for cooperating with the camera assembly, and a fourth avoidance groove C4 for cooperating with the circuit board, so as to avoid the screen assembly 12 from affecting the normal operation of these components.

[0075] In addition, the terminal 20 may further include a battery cover 22, but the battery cover 22 may also be an integral structure with the housing 21, and the embodiments of the present application do not limit this.

[0076] In summary, the embodiments of the present application provide a terminal. Among them, a screen support is provided on the back of the display module, and the display module and the screen support are connected through a first sealing layer, so as to ensure the sealing and waterproof effect between the display module and the screen support. A second sealing layer is provided on the side of the screen support facing away from the display module and is connected to the screen support. Therefore, when assembling the display screen assembly and the housing, the second sealing layer can abut against the housing to achieve the sealing and waterproof effect. And, the first connection hole of the screen support communicates with the second connection hole of the housing, so that the connected first connection hole and second connection hole can be connected through a connecting member, thereby improving the simplicity of assembling and disassembling the display screen assembly and the housing, and the waterproofness of the terminal will not be damaged during disassembly.
