Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a display screen assembly and an electronic device. Background Technology

[0002] With the development of electronic devices, long battery life has become a strong demand. In order to meet the demand for long battery life, the battery capacity needs to be increased, and the thickness of electronic devices also increases accordingly, which contradicts the demand for thinner and lighter electronic devices.

[0003] Currently, due to the influence of material manufacturing processes, it is extremely difficult to further thin out the various materials in flexible display modules. This creates a contradiction between consumer demand and actual conditions, making it difficult for electronic devices to become thinner and lighter. Summary of the Invention

[0004] This application aims to provide a display assembly and an electronic device that at least solves the problem of the difficulty in making electronic devices thinner and lighter.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a display screen assembly, comprising:

[0007] Translucent cover plate;

[0008] A metal support plate is connected to a light-transmitting cover plate, and an installation cavity is formed between the metal support plate and the light-transmitting cover plate;

[0009] The display module is located inside the mounting cavity, and the light-transmitting cover plate and the metal support plate hold the display module.

[0010] Secondly, embodiments of this application provide an electronic device, including:

[0011] Such as the display component in the first aspect.

[0012] In the embodiments of this application, when the metal support plate and the light-transmitting cover plate are connected, the metal support plate and the light-transmitting cover plate can clamp the display module, making it less prone to shifting and thus less likely to detach from the mounting position. In this case, it is not necessary to bond the metal support plate and / or the light-transmitting cover plate to the display module with optical tape. By reducing the use of optical tape, the thickness of the display assembly can be reduced.

[0013] The metal support plate of the display module provides support, preventing deformation and ensuring the stability of the displayed image. The metal support plate also has good thermal conductivity, allowing heat from the display module to be quickly dissipated when in contact with it. Furthermore, the metal support plate is electrically conductive, enabling grounding of the display module. Therefore, the metal support plate integrates support, heat dissipation, and grounding functions. In related technologies, achieving these three functions requires multiple layers. This embodiment integrates these functions with a single metal support plate, saving on multiple functional layers and reducing the thickness of the display module. This allows for a thinner and lighter electronic device when this display module is installed.

[0014] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] The following is combined Figures 1-7 This application describes a display assembly and an electronic device according to embodiments thereof.

[0029] Combination Figure 1 and Figure 4As shown, according to some embodiments of this application, the display assembly includes a light-transmitting cover plate 100, a metal support plate 200, and a display module 300. The metal support plate 200 is connected to the light-transmitting cover plate 100, and a mounting cavity 110 is formed between the metal support plate 200 and the light-transmitting cover plate 100. The display module 300 is located within the mounting cavity 110, and the light-transmitting cover plate 100 and the metal support plate 200 clamp the display module 300.

[0030] The light-transmitting cover plate 100 is light-transmitting, and light can pass through the light-transmitting cover plate 100. The metal support plate 200 is connected to the light-transmitting cover plate 100, and the metal support plate 200 and the light-transmitting cover plate 100 enclose and form an installation cavity 110, which is used to accommodate the display module 300.

[0031] When the metal support plate 200 and the light-transmitting cover plate 100 are connected, the metal support plate 200 and the light-transmitting cover plate 100 can clamp the display module 300. At this time, the display module 300 is not prone to shifting and therefore is not easy to fall out of the installation position. In this case, it is not necessary to bond the metal support plate 200 and / or the light-transmitting cover plate 100 to the display module 300 with optical tape. By reducing the use of optical tape, the thickness of the display assembly can be reduced.

[0032] The metal support plate 200 supports the display module 300, preventing deformation and ensuring the stability of the displayed image. The metal support plate 200 has good thermal conductivity, allowing heat from the display module 300 to be quickly dissipated when in contact with it. The metal support plate 200 is also conductive, enabling grounding of the display module 300. Therefore, the metal support plate 200 integrates support, heat dissipation, and grounding functions. In related technologies, achieving these three functions requires multiple layers. This embodiment integrates these functions with a single metal support plate 200, saving on multiple functional layers and reducing the thickness of the display module. This allows for a thinner and lighter electronic device when this display module is installed.

[0033] For example, the light-transmitting cover 100 can be a glass cover.

[0034] In one possible application, the metal support plate 200 can be a composite metal material (aluminum alloy / stainless steel / copper alloy, etc.).

[0035] In one possible application, the display assembly in this embodiment is a flexible display.

[0036] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, optionally, the display module 300 includes: a polarizer 310, a display panel 320, and a support and reinforcement layer 330. The polarizer 310 is attached to the light-transmitting cover plate 100, the display panel 320 is attached to the polarizer 310, and the support and reinforcement layer 330 is attached to the display panel 320. The polarizer 310, the display panel 320, and the support and reinforcement layer 330 are stacked sequentially. The light-transmitting cover plate 100 and the metal support plate 200 clamp the polarizer 310, the display panel 320, and the support and reinforcement layer 330 to limit the relative movement of adjacent layers among the polarizer 310, the display panel 320, and the support and reinforcement layer 330.

[0037] The polarizer 310, the display panel 320 and the support and reinforcement layer 330 are located in the mounting cavity 110. The support and reinforcement layer 330 supports the display panel 320. For example, the support and reinforcement layer 330 can be made of materials such as polyimide or polyethylene terephthalate.

[0038] The light-transmitting cover plate 100 and the metal support plate 200 clamp the polarizer 310, the display panel 320, and the support reinforcement layer 330, fixing them in their installation positions. Through the clamping action of the light-transmitting cover plate 100 and the metal support plate 200, the polarizer 310, the display panel 320, and the support reinforcement layer 330 do not need to be bonded together using OCA (Optically Clear Adhesive), thus saving the thickness occupied by OCA. This further reduces the thickness of the display assembly. When this display assembly is used in electronic devices, the electronic devices can be made thinner and lighter, with the display assembly thickness reduced by approximately 0.22mm or more.

[0039] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, optionally, the display module 300 further includes: a shim 340 and a display component 350. A first side of the shim 340 is attached to the support reinforcement layer 330. A portion of the display panel 320 is bent and attached to a second side of the shim 340. The bent portion of the display panel 320 is located between the shim 340 and the display component 350. The display component 350 is electrically connected to the display panel 320. The metal support plate 200 includes a first support portion 210 and a second support portion 220. The first support portion 210 and the second support portion 220 are connected. The first support portion 210 is attached to the support reinforcement layer 330. The second support portion 220 is farther from the support reinforcement layer 330 than the first support portion 210. The shim 340 and the display component 350 are located between the support reinforcement layer 330 and the second support portion 220.

[0040] A shim 340 is provided on the side of the support and reinforcement layer 330 away from the display panel 320. The display component 350 is mounted on the shim 340. The shim 340 is used to raise the display component 350 above the support and reinforcement layer 330.

[0041] Display component 350 is an electronic component in the display assembly, used to connect the circuit board 400 and the display panel 320. Therefore, display component 350 needs to be electrically connected to the display panel 320. In this embodiment, a portion of the display panel 320 is bent and connected to the display component 350. The display component 350 is raised using the shim 340, allowing the display panel 320 to bend smoothly and preventing damage from partial folding.

[0042] In the metal support plate 200, the first support portion 210 is attached to the support reinforcement layer 330, and the second support portion 220 is used to avoid the display screen component 350. Specifically, the first support portion 210 is used to clamp the display module 300 with the light-transmitting cover plate 100, and the second support portion 220 is farther away from the support reinforcement layer 330 than the first support portion 210. Since the display screen component 350 protrudes from the support reinforcement layer 330, by avoiding the display screen component 350 by the second support portion 220, it is not necessary to set the avoidance pad 340 and the structure of the display screen component 350 on the support reinforcement layer 330, thereby ensuring that the support reinforcement layer 330 can stably support the display panel 320.

[0043] In the area of ​​display component 350, a protrusion is designed to mimic the height of display component 350.

[0044] Combination Figure 3 and Figure 5 As shown, in some implementations, the display assembly may optionally include: a circuit board 400 and a sealant 500, a metal support plate 200 having mounting holes 230, a portion of the circuit board 400 passing through the mounting holes 230 and being electrically connected to the display component 350, and the sealant 500 being used to seal the gap between the circuit board 400 and the metal support plate 200.

[0045] Mounting holes 230 are provided on the metal support plate 200. A portion of the circuit board 400 can pass through the mounting holes 230, thereby connecting the circuit board 400 to the display component 350. When the circuit board 400 and the display component 350 are connected, sealant 500 is used to seal the gap between the circuit board 400 and the metal support plate 200, thereby preventing gaps between the circuit board 400 and the metal support plate 200 and preventing moisture from entering the mounting cavity 110 through the gaps between the circuit board 400 and the metal support plate 200, improving the waterproof rating of the display component and preventing corrosion of the display module 300.

[0046] like Figure 2 As shown, in some embodiments, optionally, the light-transmitting cover 100 is provided with a receiving groove 150, and at least a portion of the display module 300 is located in the receiving groove 150.

[0047] An installation cavity 110 is formed between the light-transmitting cover plate 100 and the metal support plate 200. Therefore, it is necessary to open a groove in the light-transmitting cover plate 100 and / or the metal support plate 200 so that a cavity structure can be formed between the two.

[0048] In this embodiment, a receiving groove 150 is provided on the light-transmitting cover plate 100, and the display module 300 is received in the receiving groove 150. Then, the metal support plate 200 is fastened to the groove opening of the receiving groove 150, so that the metal support plate 200 and the light-transmitting cover plate 100 enclose and form an installation cavity 110.

[0049] The thickness of the light-transmitting cover plate 100 is usually large, which makes it easy to set the receiving groove 150 on the light-transmitting cover plate 100. However, the metal support plate 200 needs to play a role in heat dissipation, so the thickness of the metal support plate 200 should not be too large, which makes it difficult to set the groove structure for accommodating the display module 300 on the metal support plate 200.

[0050] The polarizer 310, display panel 320, and support reinforcement layer 330 are first assembled together, and then placed into the receiving groove 150 as a whole. The thickness of the metal support plate 200 is approximately 0.1t.

[0051] like Figure 2 As shown, in some implementations, optionally, the side of the display module 300 is fitted against the inner wall of the receiving groove 150.

[0052] When the display module 300 is housed in the receiving groove 150, the side of the display module 300 is in contact with the inner wall of the receiving groove 150. The inner wall of the receiving groove 150 limits the display module 300, preventing the display module 300 from shaking in the receiving groove 150, which helps to improve the installation stability of the display module 300.

[0053] In one possible application, the sides of the polarizer 310, the display panel 320, and the support reinforcement layer 330 are all attached to the inner wall of the receiving groove 150. Alternatively, one or both of the polarizer 310, the display panel 320, and the support reinforcement layer 330 may be attached to the inner wall of the receiving groove 150.

[0054] like Figure 4 As shown, in some embodiments, optionally, the receiving groove 150 includes: a bottom wall 120, a first side wall 130, and a second side wall 140. The first side wall 130 and its first end are connected to the bottom wall 120, and the distance between the second end of the first side wall 130 and the bottom wall 120 is L1. A first support portion 210 is connected to the first side wall 130. The first end of the second side wall 140 is connected to the bottom wall 120, and the distance between the second end of the second side wall 140 and the bottom wall 120 is L2. A second support portion 220 is connected to the second side wall 140, wherein L2 > L1.

[0055] The first sidewall 130 and the second sidewall 140 are two opposite sidewalls in the receiving groove 150, and the length of the second sidewall 140 is greater than the length of the first sidewall 130.

[0056] The first sidewall 130 is connected to the first support portion 210, and the second sidewall 140 is connected to the second support portion 220. Since the second support portion 220 is farther away from the support reinforcement layer 330 than the first support portion 210, the distance between the second support portion 220 and the bottom wall 120 of the trench is greater than the distance between the first support portion 210 and the bottom wall 120 of the trench. The second sidewall 140 is longer, so the second sidewall 140 can be adapted to the second support portion 220. That is, the second support portion 220 does not need to be bent to connect the second sidewall 140 and the second support portion 220, which can improve the connection convenience between the second sidewall 140 and the second support portion 220.

[0057] In some implementations, the metal support plate 200 and the light-transmitting cover plate 100 may optionally be circumferentially sealed to seal the mounting cavity 110.

[0058] The metal support plate 200 can be bonded to the light-transmitting cover plate 100 with structural adhesive, thereby sealing the metal support plate 200 and the light-transmitting cover plate 100. In the display assembly, except for the circuit board 400, the rest is completely wrapped in the mounting cavity 110 formed by the light-transmitting cover plate 100 and the metal support plate 200, which solves the problem of screen distortion caused by line corrosion or silver migration short circuit after long-term use of the display assembly.

[0059] In the above embodiments, a display assembly is provided to improve the waterproof rating and reduce the thickness and weight of the display assembly, thereby further enhancing the reliability of the display assembly.

[0060] Firstly, a new type of composite metal material (aluminum alloy / stainless steel / copper alloy, etc.) is used to replace the integrated support layer assembly in related technologies. The integrated support layer assembly is used for heat dissipation, grounding, and supporting the display panel. The composite metal material is relatively large in size compared to the display panel 320. Then, by designing a recess (accommodating groove 150) on the light-transmitting cover plate 100, the functional film layers, which were originally bonded by OCA adhesive, are now freely stacked in the receiving groove 150. The X and Y directions are limited by the thin side walls of the receiving groove 150, while the Z direction is limited by the metal support plate 200 bonded to the thin side walls of the light-transmitting cover plate 100. This design allows the display assembly to eliminate the OCA adhesive stacking and integrated support layer assembly, achieving a reduction in thickness and further weight reduction.

[0061] By using composite structural adhesive, a sealed space is formed between the metal support plate 200 and the side wall of the light-transmitting cover plate 100. The installation position of the circuit board 400 is also sealed with composite structural adhesive, so that the display module 300 is completely wrapped in the sealed space formed by the metal support plate 200 and the light-transmitting cover plate 100. The waterproof rating and durability of the display module will be further improved, which will greatly reduce the water vapor corrosion of the display module 300 caused by long-term use by users, thereby avoiding display abnormality problems.

[0062] The metal support plate 200 replaces the integrated support layer, providing better impact protection for the display module 300, and further improving heat dissipation and grounding performance.

[0063] The side wall of the light-transmitting cover 100 can be designed to match the shape of the original decorative ring, thus replacing the function of the original decorative ring, enhancing the appearance and further narrowing the frame of the device, thereby improving product competitiveness.

[0064] In the embodiments of this application, an electronic device is proposed, including the display screen assembly of any of the above embodiments. The electronic device in this embodiment can achieve the technical effects of the display screen assembly of any of the above embodiments, which will not be repeated here.

[0065] Combination Figure 4 and Figure 6 As shown, in some embodiments, the electronic device may optionally include: a frame 600, a first side of a metal support plate 200 connected to a light-transmitting cover 100, and a second side of the metal support plate 200 connected to the frame 600.

[0066] In the relevant technology, the glass panel is connected to the frame 600, and there is a large contact area between the glass cover and the frame 600. The part where the glass cover and the frame 600 are connected will form a "black edge".

[0067] In this embodiment, the metal support plate 200 is connected to the frame 600, eliminating the need for the light-transmitting cover plate 100 to be connected to the frame 600. This reduces the width of the "black border". Furthermore, the second side of the metal support plate 200 can be attached to the frame 600, which further improves the connection stability between the display assembly and the frame 600.

[0068] In one possible application, the circumferential edge of the metal support plate 200 is connected to the frame 600.

[0069] Combination Figure 4 and Figure 6 As shown, in some embodiments, optionally, the frame 600 is provided with a mounting groove 610, the display assembly is located in the mounting groove 610, and the second side of the metal support plate 200 is connected to the bottom wall of the mounting groove 610.

[0070] The display assembly can be placed entirely into the mounting slot 610 of the frame 600, so that the display assembly can be flush with the frame 600, improving the flatness of the electronic device.

[0071] In this embodiment, the frame 600 does not need to be designed with the boss structure in the related technology, that is, the boss structure on the frame 600 does not need to be connected to the display screen assembly, and the display screen assembly is bonded to the bottom surface of the mounting groove 610 by structural adhesive.

[0072] Combination Figure 4 and Figure 7 As shown, in some embodiments, optionally, the light-transmitting cover 100 includes a cover portion 160 and an arc-shaped portion 170, the arc-shaped portion 170 being connected to the cover portion 160, the cover portion 160 clamping the display module 300 with the metal support plate 200, the arc-shaped portion 170 being connected to the metal support plate 200, and a portion of the metal support plate 200 being located between the circumferential outer edge of the frame 600 and the arc-shaped portion 170.

[0073] The curved portion 170 is located at the circumferential edge of the cover portion 160, which is used to clamp the display module 300 with the metal support plate 200. The curved portion 170 is bent relative to the cover portion 160 and connected to the frame 600. Since the curved portion 170 is directly opposite the circumferential outer edge of the frame 600, the electronic device has a narrower "black border".

[0074] When the light-transmitting cover 100 is designed with curved sides, the shape of the light-transmitting cover 100 replaces the decorative ring of the frame 600. That is, the plastic decorative ring of the whole machine is eliminated, the overall shape of the machine is more rounded, and the display bezel is narrower.

[0075] In one possible application, electronic devices include mobile phones, computers, personal game consoles, etc.

[0076] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0077] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
