Description

Technical Field

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

[0002] With the development of screen technology, especially the development of Active Matrix Organic Light Emitting Diode (AMOLED) displays, foldable screens have begun to be widely used, and more and more users are choosing foldable screen electronic products. However, during the use of foldable screen electronic products, because these products are constantly unfolded or folded, peeling can easily occur between the functional film layers at the bending points, such as the peeling of optical adhesive layers. This can also easily form obvious creases on the foldable screen, affecting the user experience. Summary of the Invention

[0003] This application aims to provide a screen assembly and electronic device that can solve the problem of film peeling in foldable screen electronic products in the related art.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application propose a screen assembly, including: a support structure, a first cover plate, and a flexible screen. The support structure includes a support plate and a folded edge structure disposed on the support plate. The first cover plate overlaps with the folded edge structure, and the support plate, the folded edge structure, and the first cover plate form a receiving space.

[0006] The flexible screen includes multiple functional layers stacked together, the multiple functional layers are disposed within the receiving space, and there is a gap between the multiple functional layers and the sidewall of the receiving space;

[0007] In this configuration, any two adjacent functional layers are directly bonded and connected.

[0008] Secondly, embodiments of this application provide an electronic device including the screen assembly described in the first aspect.

[0009] In the embodiments of this application, a receiving space is formed by the support plate, the folded edge structure and the first cover plate, so that multiple functional layers can be directly stacked in the receiving space. Due to the sealing effect of the first cover plate, the flexible screen including multiple functional layers can be placed on the support plate without the need to set an adhesive layer between the multiple functional layers, and the multiple functional layers will not detach from the support plate.

[0010] Furthermore, by setting gaps between multiple functional layers and the receiving space, the multiple functional layers of the screen can move within the receiving space when the screen is folded. In other words, the setting of gaps can provide space for the multiple functional layers of the screen to move within the receiving space, thereby reducing the crease phenomenon of the flexible screen.

[0011] Furthermore, since there is no need to fix adjacent functional layers by setting adhesive layers, each functional layer can deform freely, reducing the peeling problem caused by setting adhesive layers, and also reducing the crease phenomenon of flexible screens.

[0012] 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

[0021] 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.

[0022] like Figure 1 As shown, this application embodiment provides an electronic device, including a frame screen assembly 10 and a frame 20. The screen assembly 10 is a bendable or foldable screen, and the frame 20 can be understood as a structural component of the electronic device for carrying or supporting the screen assembly 10.

[0023] like Figure 2 As shown, the screen assembly 10 includes: a support structure 11, a first cover plate 12 and a flexible screen 13. The support structure 11 includes a support plate 111 and a folded edge structure 112 disposed on the support plate 111. The first cover plate 12 overlaps with the folded edge structure 112, and the support plate 111, the folded edge structure 112 and the first cover plate 12 surround to form a receiving space 14.

[0024] The flexible screen 13 includes multiple functional layers stacked together, which are disposed within the receiving space 14, and there is a gap between the multiple functional layers and the sidewall of the receiving space 14.

[0025] In this system, any two adjacent functional layers are directly connected.

[0026] The aforementioned support structure 11 can be understood as a support structure used to support the flexible screen 13, and the support plate 111 can be a hierarchical structure with good stiffness or rigidity so as to provide good support for the flexible screen 13.

[0027] The first cover plate 12 can be a bending cover plate, that is, when the user operates the screen component 10 to bend or fold, the first cover plate 12 can bend or fold together with the flexible screen 13 to protect the flexible screen 13.

[0028] Furthermore, in order to allow the content displayed on the flexible screen 13 to be shown to the user through the first cover plate 12, the first cover plate 12 can also be a light-transmitting cover plate.

[0029] In some embodiments, the first cover plate 12 can be a cover plate structure made of polyethylene terephthalate (PET) material, that is, the first cover plate 12 can be a PET cover plate with light transmission properties.

[0030] The support plate 111 can be understood as the bottom wall of the receiving space 14, the first cover plate 12 can be understood as the top wall of the receiving space 14, and the folded structure 112 can be understood as the side wall of the receiving space 14.

[0031] Optionally, the support structure 11 can be understood as a support structure with a groove, the bottom wall of which can be understood as a support plate 111, and the side wall of which can be understood as a folded edge structure 112.

[0032] For example, a plate-like structure can be stamped and folded to form a groove structure. The bottom wall of the groove structure can be understood as a support plate 111, and the side wall of the groove structure can be understood as a folded edge structure 112.

[0033] In some embodiments, the support structure 11 may be a metal structure so that the support plate 111 can have good stiffness or rigidity.

[0034] In this embodiment, a receiving space 14 is formed by the support plate 111, the folded edge structure 112 and the first cover plate 12, so that multiple functional layers can be directly stacked in the receiving space 14. Due to the sealing effect of the first cover plate 12, multiple functional layers can be placed on the support plate 111 without the need for adhesive layers, and the multiple functional layers will not detach from the support plate 111.

[0035] Furthermore, by setting gaps between multiple functional layers and the receiving space 14, multiple functional layers of the flexible screen 13 can move within the receiving space 14 when the flexible screen 13 is folded. In other words, the setting of gaps can provide space for the movement of multiple functional layers of the flexible screen 13 within the receiving space 14, thereby reducing the crease phenomenon of the flexible screen 13.

[0036] Furthermore, since there is no need to fix adjacent functional layers by setting an adhesive layer, each functional layer can deform freely, reducing the peeling problem caused by setting an adhesive layer, and also reducing the crease phenomenon of the flexible screen 13.

[0037] In addition, since there is no need to fix adjacent functional layers by setting an adhesive layer, compared with the flexible screen structure with an adhesive layer, by directly stacking each functional layer in the housing space 14, the thickness and weight of the flexible screen 13 can be reduced, which meets the development trend of the flexible screen 13 becoming thinner and lighter.

[0038] Optionally, the folded edge structure 112 includes a first folded edge 1121 and a second folded edge 1122. The first folded edge 1121 is a folded edge structure formed by extending from the edge of the support plate 111 toward a first direction. The second folded edge 1122 is a folded edge structure formed by extending from the end of the first folded edge 1121 away from the support plate 111 toward a second direction. The first cover plate 12 overlaps with the second folded edge 1122.

[0039] The sidewall of the receiving space 14 includes a first folded edge 1121, and the gap is located between the multiple functional layers and the first folded edge 1121. The first direction is the direction from the support plate 111 to the first cover plate 12, and the second direction is the direction of the first folded edge 1121 away from the support plate 111 and parallel to the support plate 111.

[0040] In this embodiment, the folded edge structure 112 can be understood as a secondary folded edge structure, including a first folded edge 1121 and a second folded edge 1122. The first folded edge 1121 can be understood as the side wall of the receiving space 14, and the second folded edge 1122 is used to overlap with the first cover plate 12 so that the support plate 111, the folded edge structure 112 and the first cover plate 12 can surround and form the receiving space 14, thereby allowing multiple functional layers of the flexible screen 13 to be stacked in the receiving space 14, and enabling the flexible screen 13 including multiple functional layers to be placed on the support plate 111 without the need for adhesive layers, so that the multiple functional layers will not detach from the support plate 111.

[0041] Moreover, by configuring the folded edge structure 112 to include a first folded edge 1121 and a second folded edge 1122, it can not only be used to enclose and form the receiving space 14, but also increase the support strength of the first folded edge 1121 to the first cover plate 12, thereby improving the structural strength of the screen assembly 10.

[0042] The first folded edge 1121 can also serve as the side wall of the receiving space 14, and there is a gap between the multiple functional layers and the first folded edge 1121. This gap is used to provide space for the movement of the multiple functional layers of the flexible screen 13 in the receiving space 14, so as to reduce the crease phenomenon of the flexible screen 13.

[0043] Alternatively, the first fold 1121 is a flange structure perpendicular to the support plate 111.

[0044] In this embodiment, by setting the first folded edge 1121 perpendicular to the support plate 111, not only can the support strength of the first folded edge 1121 on the first cover plate 12 be further improved, but the distance between the flexible screen 13 and the edge of the second folded edge 1122 can also be reduced, thereby reducing the width of the black border of the screen assembly 10.

[0045] Optionally, the screen assembly 10 further includes a first adhesive layer 15, through which the first cover plate 12 can be connected to the second folded edge 1122, so as to improve the connection strength between the first cover plate 12 and the support structure 11 and improve the structural stability of the screen assembly 10.

[0046] The first adhesive layer 15 may be an adhesive layer formed of pressure-sensitive adhesive to improve the connection strength between the first cover plate 12 and the support structure 11.

[0047] Optionally, the multiple functional layers include a light-shielding cover plate 131, a support film 132, a display panel 133, a polarizer 134, and a second cover plate 135 stacked in sequence, and the second cover plate 135 is a light-transmitting cover plate.

[0048] The light-shielding cover 131 is located between the support plate 111 and the support film 132.

[0049] The aforementioned second cover plate 135 is a light-transmitting cover plate, such as a glass cover plate.

[0050] In some implementations, the second cover plate 135 may be ultra-thin glass (UTG).

[0051] In this embodiment, since there is no need to fix adjacent functional layers by setting an adhesive layer, the light-shielding cover 131, support film 132, display panel 133, polarizer 134 and second cover 135 can be directly stacked in the receiving space 14. In this way, when a certain functional layer needs to be maintained, it is not necessary to replace the entire flexible screen 13. Only the first cover 12 needs to be removed from the support structure 11, and then the functional layer that needs to be maintained can be removed from the multiple functional layers. Moreover, when removing the functional layer that needs to be maintained, since there is no adhesive layer to fix adjacent functional layers, other functional layers will not be damaged, which effectively reduces the maintenance cost of the flexible screen 13.

[0052] For example, if the second cover plate 135 is cracked, you only need to remove the first cover plate 12 from the support structure 11 and then replace the second cover plate 135, which greatly reduces the screen replacement cost.

[0053] like Figures 4a to 4eAs shown, during the manufacturing process of the screen assembly 10, the support structure 11 can be made by stamping and folding. Then, the light-shielding cover 131, the support film 132, the display panel 133, the polarizer 134, and the second cover 135 are stacked in sequence in the receiving groove of the support structure 11. Since there is no need to set an adhesive layer between adjacent functional layers, the complex process of bonding the adhesive layer can be saved, the production process cost is optimized, and the yield of the flexible screen 13 can be improved.

[0054] Among them, a safety gap can be reserved between the edges of multiple functional layers and the first folded edge 1121 to improve the free deformation of each functional layer during the bending or folding process of the flexible screen 13.

[0055] The stacked thickness of the light-shielding cover 131, support film 132, display panel 133, polarizer 134, and second cover 135 is adapted to the height of the receiving space 14. This arrangement allows for the spacing between adjacent functional layers, thus maintaining the structural stability of the flexible screen 13 during bending or folding.

[0056] The height of the aforementioned receiving space 14 can be understood as the distance between the parallel second folded edge 1122 and the support plate 111, that is, the depth of the groove formed by the support structure 11. This groove can be understood as the receiving groove structure formed by the support plate 111 and the folded edge structure 112. When the first cover plate 12 overlaps with the second folded edge 1122, that is, when the first cover plate 12 seals the groove, it can seal the groove to form the aforementioned receiving space 14.

[0057] It should be noted that the implementation of the screen component embodiment described above is also applicable to the embodiment of the above electronic device and can achieve the same technical effect, so it will not be described again here.

[0058] like Figures 1 to 3 As shown, the electronic device also includes a frame 20, on which a receiving groove 21 is provided. The receiving groove 21 includes a first bearing surface 211 and a second bearing surface 212. The first bearing surface 211 is the bottom surface of the receiving groove 21, and the first bearing surface 211 and the second bearing surface 212 are arranged in a stepped structure.

[0059] The screen assembly 10 is disposed in the receiving groove 21, and the support plate 111 is connected to the first bearing surface 211, and the folded edge structure 112 is connected to the second bearing surface 212.

[0060] Specifically, the folded edge structure 112 includes a first folded edge 1121 and a second folded edge 1122, and the second folded edge 1122 is connected to the second bearing surface 212.

[0061] Optionally, the electronic device further includes a second adhesive layer 30 and a third adhesive layer 40, wherein the support plate 111 is connected to the first bearing surface 211 through the second adhesive layer 30, and the second folded edge 1122 is connected to the second bearing surface 212 through the third adhesive layer 40.

[0062] In this embodiment, the screen assembly 10 and the frame 20 can be fixedly connected by the second adhesive layer 30 and the third adhesive layer 40, so that the screen assembly 10 can be fixedly assembled on the frame 20.

[0063] Both the second adhesive layer 30 and the third adhesive layer 40 mentioned above can be adhesive layers formed of pressure-sensitive adhesive to improve the stability of the connection between the screen assembly 10 and the frame 20.

[0064] like Figure 5 As shown, in some embodiments, the second folded edge 1122 can also be directly overlapped on the side edge of the frame 20.

[0065] Among them, electronic devices can be mobile phones, tablets, laptops, handheld computers, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc.
