DETAILED DESCRIPTION

[0039] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art based on the present application are within the scope of protection of the present application.

[0040] The first aspect of the embodiments of the present application provides a display module, as shown in Figure 1 、 Figure 2 and Figure 3 , the display module comprises a cover plate 1, a display panel 2 and a support 3, the cover plate 1 has an extension area 11 corresponding to one side of a bending area 22 of the display panel 2, the inner boundary of the extension area 11 exceeds the outer edge of the bending area 22, as shown in Figure 2 , the area below one of the dashed lines below is the extension area 11, as shown in Figure 3 , the part outside the dashed line is the extension area 11. The display panel 2 has a display area 21, a bending area 22 and a binding area 23, the binding area 23 is oppositely arranged with the display area 21 through the bending area 22, and is located on the non-display side 2b of the display area 21, the side of the binding area 23 away from the non-display side 2b is used for binding, and comprises a first area 231 and a second area 232 arranged in turn in the direction away from the bending area 22, as shown in Figure 2 , the part between the two dashed lines is the first area 231, and the part above the upper dashed line is the second area 232, the first area 231 is used for binding electrical connection with at least one device 2312, the first area 231 comprises a first blank area 2311, the second area 232 is used for binding electrical connection with at least one adapter 2321, and the second area 232 comprises a second blank area 2322. As shown in Figure 3 、 Figure 4 , the support 3 is arranged on the side of the binding area 23 away from the non-display side 2b, and comprises a plurality of spaced apart bonding segments 31 and deformable segments 32 connecting adjacent bonding segments 31, the bonding segment 31 comprises a body part 311 extending in a first direction X and at least two support parts 312 arranged on both sides of the body part 311 in a second direction Y, the first direction X and the second direction Y are coplanar and perpendicular. The body part 311 covers at least part of the first area 231 and the second area 232, the body part 311 does not contact the device 2312 and the adapter 2321, and the body part 311 is arranged in contact with the first blank area 2311 and the second blank area 2322; the support part 312 is respectively supported on the side of the extension area 11 facing the display panel 2 and the second blank area 2322.

[0041] In this embodiment, the display side 2a refers to the side of the display panel 2 used for display, and the non-display side 2b refers to the side of the display panel 2 not used for display. In a direct understanding, the display side 2a is the front of the display panel 2, and the non-display side is the back of the display panel 2. The first area 231 can also be referred to as a device 2312 setting area. The first area 231 is used for electrical connection with at least one device 2312, and the first area 231 includes a first blank area 2311. As shown in Figure 3 The first area 231 binds a plurality of devices 2312, and includes a plurality of first blank areas 2311. The device 2312 is, for example, an IC chip electrically connected to the display panel 2. The first blank area 2311 can be understood as the spacing area between the devices 2312. Figure 3 The plurality of devices 2312 shown in the figure are spaced apart along the second direction Y. Of course, the plurality of devices 2312 can also be spaced apart along the first direction X, or the plurality of devices 2312 can be spaced apart along the first direction X and the second direction Y. The second area 232 is farther away from the bending area 22 than the first area 231, that is, the second area 232 is located at the end of the binding area 23. The second area 232 is used for electrical connection with at least one adapter 2321. The blank area without the adapter 2321 is referred to as a second blank area 2322. In an embodiment, the adapter 2321 can be, but is not limited to, a chip on film (COF) bound to the display panel 2. The display panel 2 is bound to a circuit board 4 through the chip on film. The circuit board 4 can be, but is not limited to, a flexible circuit board (FPC) or a rigid printed circuit board (PCB). In another embodiment, the adapter 2321 can also be a flexible circuit board (FPC) directly bound to the display panel 2. The body part 311 can be attached between the first blank area 2311 and the second blank area 2322 by foam or the like. In this way, the support area of the support part 3 can be increased. The support part 3 is arranged on the side of the binding area 23 away from the non-display side 2b. When the back of the display panel 2 is pressed, the support part 3 is first contacted, and thus the pressure is consumed by the support part 3. Therefore, the support part 3 can protect the bending area 22 and the devices 2312 and adapters 2321 below the bending area 22. Moreover, the support part 3 is composed of a plurality of attached segments 31 and deformable segments 32 located between adjacent attached segments 31, that is, the support part 3 is arranged in segments. The attachment stress can be absorbed by the deformable segments 32, so that the stress received by the support part 3 at different positions, such as edge positions and center positions, is more uniform. There is no large deformation stress at the edge position, thereby solving the problem of easy warping of the support part 3 at the edge, and making the attachment of the support part 3 more flat and firm.

[0042] In some embodiments of the present application, as shown in Figure 5 The thickness of the deformable segment 32 is smaller than the thickness of the attached segment 31. The smaller thickness of the deformable segment 32 can improve the flexibility of the deformable segment 32, so that the deformable segment 32 has the ability to deform.

[0043] Optionally, the thickness of the deformable section 32 is 0.4-0.6 times the thickness of the fitting section 31, for example, it can be 0.4 times, 0.45 times, 0.5 times, 0.55 times, 0.6 times, etc.

[0044] The thickness of the deformable section 32 is 0.4-0.6 times the thickness of the fitting section 31, so that the deformable section 32 can have certain deformability and also have sufficient connection strength.

[0045] In some embodiments of the present application, as shown in Figure 1 , Figure 4 and Figures 5 to 7 , the deformable section 32 is integrally formed with the fitting section 31, and at least one surface of the deformable section 32 in the thickness direction is recessed relative to the corresponding surface of the fitting section 31.

[0046] The deformable section 32 is integrally formed with the fitting section 31, which is conducive to improving the connection strength between the deformable section 32 and the fitting section 31, thereby improving the overall strength of the support 3. The deformable section 32 and the fitting section 31 can be integrally formed by injection molding. Alternatively, a support 3 mother piece with uniform thickness can be formed first, and then the mother piece is thinned from one side or both sides to obtain the support 3.

[0047] The deformable section 32 is integrally formed with the fitting section 31, which is conducive to improving the connection strength between the deformable section 32 and the fitting section 31, thereby improving the overall strength of the support 3. The deformable section 32 and the fitting section 31 can be integrally formed by injection molding. Alternatively, a support 3 mother piece with uniform thickness can be formed first, and then the mother piece is thinned from one side or both sides to obtain the support 3.

[0048] In some embodiments of the present application, as shown in Figure 5 , Figure 6 , the deformable section 32 is in a wave shape or the deformable section 32 is provided with a plurality of through holes 321 or blind holes.

[0049] The wave-shaped structure is like a small spring and is easy to deform. When subjected to external force, the wave-shaped deformable section 32 can disperse stress to each curved portion, avoiding stress concentration at a certain point and causing damage. Therefore, making the deformable section 32 into a wave shape can quickly absorb stress generated from the fitting sections 31 on both sides, avoiding stress concentration in the fitting sections 31 and warping phenomenon.

[0050] A plurality of through holes 321 or blind holes are arranged in the deformable section 32, which further weaken the mechanical strength of the deformable section 32, so that the deformable section 32 is easier to deform, more energy can be absorbed by deformation, so that the stress of the two side bonding sections 31 can be better released, and the warping phenomenon is not easy to occur. Among them, the through holes 321 or blind holes can be arranged in an array, so as to reduce the risk of local strength being too low and breaking.

[0051] In some embodiments of the present application, as shown in Figure 7 The deformable section 32 includes a first part 322 integrally formed with the bonding section 31 and a second part 323 arranged on one side of the first part 322, and the second part 323 is made of an elastic material.

[0052] The second part 323 and the first part 322 jointly constitute the deformable section 32, and the second part 323 is made of an elastic material such as a PET film (Polyethylene Terephthalate Film), a PE (Polyethylene) film, silica gel or foam, etc. It can improve the deformation ability of the deformable section 32 and effectively absorb the deformation generated by the two side bonding sections 31.

[0053] In addition, the deformable section 32 composed of the first part 322 and the second part 323, compared with the deformable section 32 integrally formed with the bonding section 31, the thickness of the first part 322 made of a conventional material such as a conventional metal material can be smaller, so the flexibility of the first part 322 will be better, combined with the second part 323 made of an elastic material, so that the deformable section 32 has both sufficient connection strength and good deformability.

[0054] It should be noted that the first part 322 and the second part 323 can be integrated by bonding, for example, a back adhesive can be coated on the first part 322 or the second part 323, or glue or hot melt adhesive can be coated on the first part 322 or the second part 323.

[0055] In some embodiments of the present application, as shown in Figure 8 The deformable section 32 and the bonding section 31 are arranged independently, and the deformable section 32 is arranged on the side of the bonding section 31 away from the bonding surface.

[0056] The bonding section 31 consists of multiple independent segments connected into a single unit by the deformable section 32. The deformable section 32 is located on the side of the bonding section 31 furthest from the bonding surface, increasing the bonding area between the deformable section 32 and the bonding section 31 and ensuring a good bond. Furthermore, stress generated by the bonding section 31 can be released at the points where the bonding section 31 breaks, with only a small portion being transferred to the deformable section 32 and absorbed thereafter. This reduces the risk of warping at both ends of the support member 3 and causing incomplete bonding. The deformable section 32 can be made of elastic materials such as PET film, PE film, silicone, or foam, or it can be made of conventional materials and have multiple through holes 321 or blind holes.

[0057] To ensure a proper fit between the support component 3 and the binding area 23, such as Figures 9 to 12 As shown, the main body 311 has three support portions 312 on both sides along the second direction Y, that is, in the width direction of the main body 311. The line connecting the center points of the three support portions 312 forms a triangle. In this way, the three support portions 312 form a stable triangular support to ensure that when the support member 3 is attached to the binding area 23, it can be stably supported above the binding area 23, thus better protecting the device 2312 and the adapter 2321.

[0058] Optionally, the lines connecting the center points of the support portions 312 form an acute triangle, meaning that no two support portions 312 located on either side of the main body portion 311 are arranged opposite each other. This makes the positions of the three support portions 312 on the mating section 31 more dispersed, and since all three angles are acute, the three sides of the triangle can better maintain stability when pulled together.

[0059] Optionally, such as Figures 9 to 12 As shown, there is one support portion 312 supporting the outer extension region 11, referred to as the first support portion 3121, and two support portions 312 supporting the second blank area 2322, referred to as the second support portion 3122. The second support portion 3122 is located between the two first support portions 3121, and the length of the first support portion 3121 is greater than that of the second support portion 3122.

[0060] In this embodiment, the available space in the extension area 11 is relatively large, so a long continuous first support portion 3121 is provided to improve the support effect on the main body portion 311. In the second blank area 2322, since the adapter 2321 needs to be avoided, the length of the support portion 312 is limited by space, and its size is difficult to increase. Therefore, two support portions 312 are provided to ensure the support effect on the main body portion 311.

[0061] like Figures 9 to 12As shown, the first support part 3121 is folded from the body part 311 towards the display panel 2, and the second support part 3122 is folded from the body part 311 towards the display panel 2 in an L shape. The first support part 3121 is directly folded from the body part 311 once, and the support area of the support part 312 is equal to the thickness of the body part 311 multiplied by the extension length of the first support part 3121. Compared with the L-shaped second support part 3122, the first support part 3121 is narrower, and it is beneficial to reduce the frame when it is arranged in the outer extension area 11. While the L-shaped second support part 3122 is relatively wide, which is beneficial to increase the bonding area between the second support part 3122 and the second blank area 2322, thereby improving the bonding effect of the support piece 3.

[0062] In order to further improve the warping problem of the two ends of the support piece 3, as shown in FIG. 6, the support part 312 is provided with a non-void bonding structure 3123. Figures 9 to 12 As shown, the support part 312 is provided with a non-void bonding structure 3123, which adjusts the position of the bonding surface of the support part 312 and the outer extension area 11 and the second blank area 2322. Due to the slight difference in the flatness of the bonding surface of the binding area 23, and the slight deformation of the support piece 3 during bonding, the absolutely flat support part 312 is easy to cause void bonding. By providing the non-void bonding structure 3123 on the support part 312, the bonding surface of the support part 312 changes the bonding position through the non-void bonding structure 3123 to adapt to the changes and reduce the risk of void bonding of the support part 312.

[0063] Further, considering that the area with the largest deformation is the position of the two ends of the support piece 3, the non-void bonding structure 3123 can be provided on the support part 312 of the bonding section 31 at the two ends of the support piece 3.

[0064] Of course, in order to ensure the non-void bonding effect of the support piece 3, the non-void bonding structure 3123 can be provided on the support part 312 of each bonding section 31.

[0065] In some embodiments of the present application, as shown in FIG. 6, the non-void bonding structure 3123 is a bonding surface with a concave-convex texture structure; or, as shown in FIG. 7, the non-void bonding structure 3123 is a bonding surface arranged in an inclined manner. Figure 9 Figure 10

[0066] The concave-convex texture structure makes the height position of the bonding surface of the support part 312 always in a changing state, which can better adapt to the slight difference in the flatness of the surface of the binding area 23 or the slight deformation of itself, thereby ensuring that the outer extension area 11 and the second blank area 2322 can be closely matched, and the non-void bonding phenomenon is not easy to occur.

[0067] ​​The anti-virtual pasting structure 3123 is an inclined pasting surface, that is, the support surface of the support part 312 is a non-planar structure design, so that when the support part 312 of the support piece 3 is pasted with the module, even if there is slight deformation, it can still be well pasted with the module.

[0068] The inclination angle of the anti-virtual pasting structure 3123 should not be too large, otherwise it will also cause partial virtual pasting or film printing, which cannot be covered even if pasted with foam or foam glue. The inclination angle can be controlled within 1°-5°.

[0069] In some embodiments of the present application, as shown in Figure 11 The anti-virtual pasting structure 3123 is at least a first pasting surface 31231 and a second pasting surface 31232 arranged horizontally and having a height difference; or as shown in Figure 12 The anti-virtual pasting structure 3123 is at least a first pasting surface 31231 and a second pasting surface 31232 arranged obliquely and having different inclination angles.

[0070] The first pasting surface 31231 and the second pasting surface 31232 having a height difference can make the support piece 3 adapt to the different step surfaces of the module, avoiding the risk of complete virtual pasting of a certain support part 312. The height difference between the first pasting surface 31231 and the second pasting surface 31232 can be designed to be 0.05mm-0.15mm, such as 0.05mm, 0.1mm, 0.15mm, etc. As shown in Figure 11 The first pasting surface 31231 is a surface with a higher support height, the second pasting surface 31232 is a surface with a lower support height, and the third pasting surface 31233 has the same support height as the first pasting surface 31231.

[0071] The pasting surface of a single support part 312 having a height difference is not limited to the first pasting surface 31231 and the second pasting surface 31232, but can also include a third pasting surface 31233 or even more. The heights of the first pasting surface 31231, the second pasting surface 31232 and the third pasting surface 31233 are different, or the heights of two non-adjacent pasting surfaces are the same.

[0072] In addition, 0.1mm-0.15mm thick pasting glue is pasted on the anti-virtual pasting structure 3123, or 0.1mm-0.15mm thick pasting glue + foam + glue structure is pasted, which can make the anti-virtual pasting structure 3123 transition uniformly at the step position, avoiding film printing at the step position.

[0073] As shown in Figure 12As shown, the anti-lagging structure 3123 can also be a first bonding surface and a second bonding surface 31232 with different tilt angles, that is, the bonding surface of the anti-lagging structure 3123 is set as a double-sloped surface, so as to better fit and adapt to the module. Of course, the anti-lagging structure 3123 is not limited to double-sloped surfaces, but can also be triple-sloped, quadruple-sloped, etc. The tilt angle of each bonding surface can be controlled within the range of 1°-5°.

[0074] In some embodiments of this application, such as Figure 13 As shown, the main body 311 has an opening 3111 at the position corresponding to the device 2312. The shape of the opening 3111 is not limited to... Figure 13 The shape shown can be modeled after device 2312, or it can be a simple parallelogram structure.

[0075] By providing an opening 3111 at the position corresponding to the device 2312 in the main body 311, the opening 3111 is used to avoid the device 2312 below, so that when the support member 3 is placed above the binding area 23, the main body 311 does not contact the surface of the device 2312, and there is no need to set the support height of the support member 3 to be greater than the height of the device 2312 itself. That is to say, the height of the support member 3 can be approximately the same as the height of the device 2312. This can improve the support strength of the support member 3 and reduce the space occupied by the support member 3 in the internal space of the display module, which is beneficial to reducing the thickness of the display module.

[0076] The second aspect of this application provides a terminal device, which can be, but is not limited to, an in-vehicle computer, a laptop computer, a mobile phone, a wearable device, etc., and includes the display module described above. The display module of the terminal device includes a support member 3, which is composed of multiple bonding segments 31 and deformable segments 32 located between adjacent bonding segments 31. That is, the support member 3 is segmented, and the bonding stress can be absorbed by the deformable segments 32, so that the stress on the support member 3 at different positions, such as the edge position and the center position, is more uniform, and there is no large deformation stress at the edge position. This solves the problem that the support member 3 is prone to warping at the edge, and makes the bonding of the support member 3 more flat and firm. Moreover, the support member 3 can protect the device 2312 and the adapter 2321 below. That is, when the terminal device is under pressure, the pressure is first absorbed by the support member 3, and is not transmitted to the device 2312 and the adapter 2321 below, so as not to damage them.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
