[0039] In LCD products, since the display module includes a double-layer glass substrate and is fixed with an iron frame and a plastic frame for the backlight on the back, it generally does not bend and the module structure is relatively stable. However, the current OLED module has a substrate of PI film, which is a flexible material, and the back is mostly made of foam, metal foil and other materials, making the entire module soft. This results in the flexible circuit board (FPC) and circuit board (PCB) areas being very easy to bend in the laminated structure. Whether it is the wiring on the display substrate, the bonding area of ​​the FPC, or the FPC itself, they are all relatively fragile. When the product is frequently bent, these locations are prone to tearing (crack), warping or peeling, causing product failure. In particular, for products where the FPC is not bent to fit and fix on the back of the display product, such products are particularly prone to loosening or tearing of the FPC binding position.

[0040] Specifically, taking notebook products as an example, due to the high requirements for screen thickness, notebook products generally use FPC without bending, such as Figure 1 As shown in the stacking diagram, in the display module of the related art, the display area AA of the module uses optical adhesive (OCA) 10 to fix the touch substrate 7 and the display substrate 1 and other structures on the cover plate 6, while in the flexible circuit board and circuit board area BB, due to the presence of components such as IC 9, FPC 200, and inductor components 500, the flatness is poor, and it is difficult to fix this part to the cover plate 6 with adhesive materials such as OCA and PSA. In addition, due to the narrow frame of the terminal product, this part is often outside the cover plate 6, and then hidden under the keyboard of the notebook in the subsequent process. When this module design is shipped, the FPC 200 and PCB 400 are both in an active state. As a result, it is easy to cause the loosening of the FPC binding position or the tearing of the FPC during the turnover of the module product and the assembly of the whole machine.

[0041] In view of the above research findings of the inventors, the present application provides a design solution for a display substrate to solve the problem that the FPC binding position of OLED display products is easily loosened or torn.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] It should be understood that the terms used to describe the embodiments of the present invention are not intended to limit and / or define the scope of the present invention. For example, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by a person of ordinary skill in the art. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Unless the context clearly indicates otherwise, the singular form "one", "one" or "the" and other similar words do not indicate a quantitative limitation, but rather indicate the presence of at least one. In addition, it is understood that the 'edge' described in the present application refers to a portion defining the outer contour of the structure, which may include the edge and / or boundary of the structure; for example, the edge of the display substrate refers to the edge of the display substrate; in the support plate, one side of the first part is connected to the second part, and the other side of the first part forms the edge of the support plate, and further, the edge of the first part includes both the edge and the boundary distinguishing it from the second part.

[0044] like Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present application provides a display module, which includes:

[0045] The display substrate 1 has a first side 11;

[0046] The circuit board 2 is arranged at the first side 11 of the display substrate 1 and is electrically connected to the display substrate 1;

[0047] The support plate 3 is arranged on the non-display side of the display substrate 1; the support plate 3 is bendable and includes a first part 31 and a second part 32, wherein the second part 32 is provided with a hollow opening; the display substrate 1 is located in the first part 31 and is fixedly connected to the first part 31; the circuit board 2 is located in the second part 32 and is fixedly connected to the second part 32.

[0048] The display module provided in the embodiment of the present application is provided with a bendable support plate 3 on the back side (non-display area side) of the display substrate 1, and the support plate 3 includes a first part 31 and a second part 32, and the display substrate 1 and the circuit board 2 are respectively arranged on the first part 31 and the second part 32. Specifically, the first part 31 can fix and support the display substrate 1, and the second part 32 can fix and support the circuit board 2. Therefore, when the display module is flattened for shipment, the display substrate 1 and the circuit board 2 are relatively stable, and the mechanical firmness is strong, and the problem of loosening or tearing of the binding position of the circuit board 2 is not easy to occur. In addition, the second part 32 of the support plate 3 is provided with a hollow opening, which has a strong bending performance and can be bent with the circuit board 2 according to the needs, especially when the circuit board 2 is arranged around the rotating shaft of a folding display product (such as a notebook), the second part 32 of the support plate 3 can be repeatedly bent around the rotating shaft, thereby meeting the needs of repeated folding of the display product.

[0049] In summary, the display module provided in the embodiment of the present application is not prone to loosening or tearing of the binding position of the circuit board 2, and can solve the mechanical reliability problem of the display module during transportation and processing.

[0050] In a specific embodiment, in the embodiment of the present application, the support plate is an integrated structure.

[0051] Exemplarily, the support plate may be a stainless steel plate (SUS).

[0052] Specifically, the SUS material can achieve a small radius bending of 2mm-5mm and can meet the requirement of 200,000 repeated bendings. Furthermore, the display terminal can meet the requirement of arranging the circuit board 2 and the second part of the support plate around the rotation axis.

[0053] In addition, the support plate is made of stainless steel and is located on the back of the display substrate, which can be used as a heat dissipation structure of the display module; furthermore, the display module provided in the embodiment of the present application can omit the heat dissipation module (SCF) in conventional display products (refer to Figure 1 (SCF 101 in ).

[0054] Exemplarily, in the embodiment of the present application, the thickness of the support plate may be 50 μm-200 μm.

[0055] In a specific embodiment, Figure 2 and Figure 4 As shown, the circuit board 2 includes a soft part 20 and a hard part 4. The hard part 4 is located on a side of the soft part 20 away from the display substrate 1. The soft part 20 is bendable.

[0056] Exemplarily, the soft part and the hard part may be an integrated structure (such as a flexible circuit board FPC), wherein the electrical components are disposed on the hard part.

[0057] Or, if Figure 2 and Figure 4 As shown, the soft part 20 and the hard part 4 may also be separate structures, the soft part 20 may be a chip on film (COF), the hard part 4 may be a circuit board (PCB), and the soft part 20 and the hard part 4 are bound and connected.

[0058] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, the second part 32 of the support plate 3 includes a connecting part 321 and a fixing part 322, and the connecting part 321 is provided with a hollow opening; the fixing part 322 is located on the side of the connecting part 321 away from the first part 31; the soft part 20 of the circuit board 2 is located at the connecting part 321, and the hard part 4 of the circuit board 2 is located at the fixing part 322 and fixedly connected to the fixing part 322.

[0059] Specifically, the connection portion 321 of the support plate 3 and the soft portion 20 of the circuit board 2 can be bent according to actual product requirements, for example, Figure 6 As shown, the connection portion 321 of the support plate 3 and the soft portion 20 of the circuit board can be arranged around the hinge assembly 100 of the foldable display product (such as a notebook). At this time, the connection portion 321 of the support plate 3 and the soft portion 20 of the circuit board can be repeatedly bent around the hinge assembly 100, thereby meeting the requirement of repeated folding of the display product. In the embodiment of the present application, a hollow opening is provided at the connection portion 321 of the support plate 3, which can further improve the bending performance at the connection portion 321, thereby enabling the support plate 3 to better meet the bending requirements of the display product.

[0060] Specifically, Figure 2 As shown, the support plate 3 includes a first portion 31, a connecting portion 321 and a fixing portion 322 which are connected in sequence, the connecting portion 321 is located between the first portion 31 and the fixing portion 322, the hard portions 4 of the display substrate 1 and the circuit board 2 are respectively located at the first portion 31 and the fixing portion 322, and are respectively fixedly connected to the first portion 31 and the fixing portion 322, that is, the hard portions 4 of the display substrate 1 and the circuit board 2 are respectively fixed on the support plate 3, so that the display substrate 1 and the circuit board 2 can be relatively fixed, the mechanical firmness of the entire module is enhanced, and the mechanical reliability of the display module during transportation and processing can be effectively improved.

[0061] In a specific embodiment, Figure 2 and Figure 3 As shown, the projection of the hard part 4 on the plane where the support plate 3 is located roughly coincides with the fixing portion 322; in other words, the projection of the edge of the hard part 4 on the plane where the support plate 3 is located is close to the edge of the fixing portion 322 of the support plate 3 and has roughly the same extension trend.

[0062] Exemplarily, the spacing between the projection of the edge of the hard part 4 on the plane where the support plate 3 is located and the edge of the closest fixing part 322 is 0-0.5mm, that is, the spacing between the projection of each edge of the hard part 4 on the plane where the support plate 3 is located and the corresponding edges in the fixing part 322 is less than or equal to 0.5mm.

[0063] For example, Figure 2 and Figure 3 As shown, the hard part 4 of the circuit board 2 and the fixing part 322 of the support board 3 are both rectangular, and the sides of the two rectangles are correspondingly arranged, and the two correspondingly arranged sides are parallel and the projection spacing is within the range of 0-0.5mm.

[0064] In a specific embodiment, Figure 2 As shown, the hard portion 4 includes a second edge 41 , and the second edge 41 is close to the first edge 11 of the display substrate 1 .

[0065] For example, Figure 2 and Figure 3 As shown, the projections of the other edges of the hard part 4 except the second edge 41 on the plane where the support plate 3 is located do not overlap with the fixed portion 322 of the support plate 3. In other words, the projections of the other edges of the hard part 4 except the second edge 41 surround the corresponding edges of the fixed portion 322, or most of the edges of the fixed portion 322 of the support plate 3 are retracted relative to the edges of the hard part 4. In this way, the required space between the hard part 4 and the fixed portion 322 can be reduced as much as possible, and the volume of the whole machine can be reduced.

[0066] For example, the projections of the other edges in the hard part 4 except the second edge 41 exceed the corresponding nearest edges in the fixed part 322, and the excess size can be 0.5mm, or 0.4mm, 0.3mm, 0.2mm, or 0.1mm; the second edge 41 of the hard part 4 is aligned with the parallel and nearest edge in the fixed part 322, which is equivalent to the projection of the second edge 41 on the plane where the support plate 3 is located and the distance between the edge of the closest fixed part 322 is 0.

[0067] For example, Figure 2 and Figure 3 As shown, the connection portion 321 of the support plate 3 is rectangular and has two pairs of opposite sides, wherein the first pair of sides are respectively connected to the first portion 31 and the fixing portion 322, and the second pair of sides exceeds the two side edges of the soft portion 20 of the circuit board 2. For example, the soft portion 20 includes at least two flexible connectors 200 arranged along the first side 11 of the display substrate 1, and the second pair of sides of the connection portion 321 exceeds the outer sides of the two flexible connectors 200 at both ends.

[0068] In a specific embodiment, Figure 2 and Figure 3As shown, the projection of the display substrate 1 on the plane where the support plate 3 is located roughly coincides with the first portion 31; in other words, the projection of the edge of the display substrate 1 on the plane where the support plate 3 is located is close to the edge of the first portion 31 of the support plate 3 and has roughly the same extension trend.

[0069] Exemplarily, the spacing between the projection of the edge of the display substrate 1 on the plane where the support plate 3 is located and the edge of the closest first part 31 is 0-0.5mm, that is, the spacing between the projection of each edge of the display substrate 1 on the plane where the support plate 3 is located and the corresponding edges in the first part 31 is less than or equal to 0.5mm.

[0070] For example, Figure 2 and Figure 3 As shown, the display substrate 1 and the first portion 31 of the support plate 3 are both rectangular, and the sides of the two rectangles are correspondingly arranged, and the two correspondingly arranged sides are parallel and the projection interval is within the range of 0-0.5mm.

[0071] In a specific embodiment, Figure 4 As shown, the display module provided in the embodiment of the present application may further include a cover plate 6 located on a side of the display substrate 1 away from the support plate 3 .

[0072] Exemplarily, the cover plate may be made of a flexible material, such as a PI material. Figure 2 and Figure 3 As shown, the projections of the other edges of the first part 31 of the support plate 3, except the edge close to the second part 32, on the plane where the display substrate 1 is located do not overlap with the display substrate 1. In other words, most of the edges of the first part 31 of the support plate 3 surround the edges of the display substrate 1. In this way, the first part 31 of the support plate 3 can achieve better support and protection for the entire display substrate 1, so as to make up for the problem of insufficient support capacity of the flexible cover plate, thereby effectively improving the strength of the display substrate 1.

[0073] For example, the projections of the edges of the first part 31 of the support plate 3 except the edges close to the second part 32 on the plane where the display substrate 1 is located exceed the corresponding nearest edges in the display substrate 1, and the excess size can be 0.5mm, or 0.4mm, 0.3mm, 0.2mm, or 0.1mm; the projections of the edges of the first part 31 of the support plate 3 close to the second part 32 on the plane where the display substrate 1 is located are retracted relative to the corresponding nearest edges in the display substrate 1 that extend in the same direction, and the retracted size can be 0.5mm, or 0.4mm, 0.3mm, 0.2mm, or 0.1mm.

[0074] Of course, the cover plate of the display module can also be a rigid material, such as glass. In this case, the projections of the other edges of the display substrate 1 except the first edge 11 on the plane where the support plate 3 is located can have no overlap with the first portion 31. That is, most of the edges of the first portion 31 of the support plate 3 are retracted relative to the edges of the display substrate 1. In this way, the required space between the display substrate 1 and the first portion 31 of the support plate 3 can be reduced as much as possible, the volume of the whole machine can be reduced, and it is conducive to the narrow frame design of the display product.

[0075] In a specific embodiment, Figure 2 and Figure 3 As shown, along the extension direction of the first side 11 of the display substrate 1 , the widths of the connecting portion 321 and the fixing portion 322 of the support plate 3 are both smaller than the width of the first portion 31 .

[0076] For example, Figure 2 and Figure 3 As shown, along the extension direction of the first side 11 of the display substrate 1 , the widths of the connecting portion 321 and the fixing portion 322 of the support plate 3 may be the same.

[0077] The above-mentioned dimension design can ensure the strength and supporting performance of the support plate on the one hand, and help improve the bending performance of the connecting portion of the support plate on the other hand. In addition, it can also reduce the area of ​​the support plate as much as possible, which is beneficial to the assembly of the display module.

[0078] In a specific embodiment, Figure 4 As shown, the hard parts 4 of the display substrate 1 and the circuit board 2 are respectively attached to and fixed on the support plate 3 .

[0079] For example, Figure 4 As shown, the display substrate 1 includes a display panel 12 and a back film 13 located between the display panel 12 and the support plate 3. The display module includes a first adhesive layer 51, which is located between the back film 13 and the first part of the support plate 3, and the back film 13 and the first part of the support plate 3 are fixedly connected through the first adhesive layer 51.

[0080] For example, Figure 4 As shown, the display module further includes a second adhesive layer 52 , which is located between the hard portion 4 of the circuit board 2 and the fixed portion of the support plate 3 , and the hard portion 4 of the circuit board 2 and the fixed portion of the support plate 3 are fixedly connected via the second adhesive layer 52 .

[0081] Exemplarily, the first adhesive layer and the second adhesive layer may be optical adhesive (OCA) or pressure sensitive adhesive (PSA).

[0082] Specifically, in the actual assembly process, such as Figure 4As shown, the first adhesive layer 51 can be provided on the support plate 3 , and the second adhesive layer 52 can be provided on the support plate 3 or on the hard part (eg circuit board) 4 of the circuit board 2 .

[0083] In a specific embodiment, Figure 2 and Figure 3 As shown, the hard part 4 of the circuit board 2 is provided with a first positioning hole 40; the fixing portion 322 of the support plate 3 is provided with a second positioning hole 30 corresponding to the first positioning hole 40, and the projection of the first positioning hole 40 on the plane where the support plate 3 is located overlaps with the second positioning hole 30.

[0084] For example, Figure 2 As shown, the hard part 4 is a strip-shaped plate extending along the first side 11 of the display substrate 1 ; the hard part 4 is provided with two first positioning holes 40 , and the two first positioning holes 40 are respectively located at two ends of the hard part 4 .

[0085] Specifically, the alignment of the first positioning hole 40 and the second positioning hole 30 can facilitate the mutual positioning of the hard portion 4 of the circuit board 2 and the support plate 3 .

[0086] For example, Figure 2 As shown, the display module provided in the embodiment of the present application may further include a connector (not shown in the figure), which is configured to penetrate the first positioning hole 40 and the second positioning hole 30 to fix the hard part 4 of the circuit board 2 to the fixing part 322 of the support plate 3.

[0087] Exemplarily, the connection member may include a screw.

[0088] In a specific embodiment, Figure 5 As shown, the connection portion 321 of the support plate is provided with a hollow opening, and the hollow opening includes at least two rows of through holes 320, each row of through holes 320 is arranged along the extension direction of the first side of the display substrate, and the through holes 320 in the odd-numbered rows are at least partially staggered with the through holes 320 in the even-numbered rows. In this way, while ensuring the supporting strength of the connection portion 321, the bending performance of the connection portion 321 can be effectively improved, so that the connection portion 321 can be bent with a small radius and can be bent repeatedly.

[0089] Exemplarily, the through hole may be a strip-shaped hole extending along the extending direction of the first side of the display substrate.

[0090] Specifically, Figure 2As shown, the connection portion 321 of the support plate 3 is bent along with the soft portion 20 of the circuit board 2, and its bending axis is the same as the extension direction of the first side 11 of the display substrate 1. The through hole on the connection portion 321 is set to be a strip hole with the same extension direction as the first side 11, that is, the extension direction of the through hole is the same as the extension direction of the bending axis, which is beneficial to improving the bending performance of the connection portion 321.

[0091] In a specific embodiment, in the display module provided in the embodiment of the present application, the display substrate is an OLED flexible substrate.

[0092] In a specific embodiment, the display module provided in the embodiment of the present application may also include other structures, for example, Figure 4 As shown, it may also include a touch substrate 7, a touch flexible circuit board 8, an integrated circuit (IC) 9, an optical glue 10 for bonding the cover plate 6, and the like.

[0093] In addition, an embodiment of the present application further provides a display device, which includes a display module as described above.

[0094] In a specific embodiment, the display device provided in the embodiment of the present application may be a notebook product.

[0095] For example, Figure 6 As shown, the display device provided in the embodiment of the present application further includes a keyboard assembly 300 and a hinge assembly 100; the hinge assembly 100 is located at the first side of the display substrate 1, and the keyboard assembly 300 is connected to the display substrate 1 through the hinge assembly 100. Specifically, the keyboard assembly 300 and the display substrate 1 are pivotally connected through the hinge assembly 100.

[0096] Further, such as Figure 6 As shown, the second portion 32 of the circuit board and the support plate 3 crosses the hinge assembly 100 and extends into the keyboard assembly 300 ; and the second portion 32 of the circuit board and the support plate 3 can be bent around the hinge assembly 100 .

[0097] Exemplarily, the soft part 20 of the circuit board and the connecting part 321 of the support plate 3 are arranged around the hinge assembly 100 and can be bent around the hinge assembly 100; the hard part 4 of the circuit board and the fixing part 322 of the support plate 3 extend into the keyboard assembly 300.

[0098] For example, the keyboard assembly includes a shell and a keyboard disposed on the upper portion of the shell, and the hard portion of the circuit board and the fixing portion of the support plate extend into the shell and are hidden under the keyboard.

[0099] Of course, the display device provided in the embodiment of the present application is not limited to notebooks, but can also be applied to mobile phones, tablet computers or other display products. In addition, the display device is particularly suitable for products with narrow bezels, FPC exposed outside the cover, or flexible displays, such as multi-sided curved display products.

[0100] Specifically, the display device provided in the embodiment of the present application adopts a design of setting a support plate on the back of the display substrate and the circuit board, which solves the problem that the binding position of the circuit board is prone to loosening or tearing, and improves the mechanical reliability of the display module during transportation and processing.
