Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display module. Background Technology

[0002] In existing display modules, after the display panel and backlight module are bonded together, the flexible circuit board and printed circuit board are wrapped along the edge of the product with edge-sealing tape to prevent light leakage from the side of the product and to strengthen the bond between the display panel and the backlight module.

[0003] Currently, adhesive tape is typically used to secure the edge binding tape to the flexible circuit board and printed circuit board (PCB) to prevent the PCB from colliding with other components and causing noise. The adhesive underneath the edge binding tape is usually a single strip that runs through both the PCB and the PCB. When removing the edge binding tape for rework of the display module, because the tape and PCB are secured by adhesive, the PCB, already bonded to the display panel and PCB, can easily be torn off during the tape removal process. This can worsen damage to the display module or even render it unusable, leading to a lower rework yield.

[0004] Therefore, it is necessary to provide a display module to improve this deficiency. Utility Model Content

[0005] This application provides a display module that can improve the rework yield.

[0006] To achieve the above objectives, according to a first aspect of this application, a display module is provided, having a front side and a back side disposed opposite to each other in the thickness direction of the display module, and comprising:

[0007] Display panel, including the mounting section;

[0008] A flexible circuit board is electrically connected to the bonding portion;

[0009] A printed circuit board, electrically connected to the flexible circuit board;

[0010] An edge-sealing component extends from the front side to the back side and covers the flexible circuit board and the printed circuit board;

[0011] The display module further includes a first adhesive portion and a second adhesive portion. The edge-binding component is bonded to the flexible circuit board through the first adhesive portion, and the edge of the first adhesive portion is recessed inward relative to the edge of the flexible circuit board. The edge-binding component is bonded to the printed circuit board through the second adhesive portion, and the first adhesive portion and the second adhesive portion are separate from each other.

[0012] Optionally, the indentation distance between the side edge of the first adhesive portion near the bonding portion and the corresponding side edge of the flexible circuit board is greater than or equal to the indentation distance between the other side edge of the first adhesive portion and the corresponding side edge of the flexible circuit board.

[0013] Optionally, the difference between the recessed distance between the side edge of the first adhesive portion near the binding portion and the corresponding side edge of the flexible circuit board and the recessed distance between the other side edge of the first adhesive portion and the corresponding side edge of the flexible circuit board is greater than or equal to 0.5 mm and less than or equal to 1 mm.

[0014] Optionally, the indentation distance between the edge of the first adhesive portion and the corresponding side edge of the flexible circuit board is greater than or equal to 0.8 mm and less than or equal to 2 mm.

[0015] Optionally, the orthographic projection of the first adhesive portion on the reference plane is located within the orthographic projection of the flexible circuit board on the reference plane, and the reference plane is parallel to the light-emitting surface of the display panel.

[0016] Optionally, the edge of the second adhesive portion is recessed inward relative to the edge of the printed circuit board.

[0017] Optionally, the second adhesive portion is spaced apart from the flexible circuit board.

[0018] Optionally, the distance between the second adhesive portion and the flexible circuit board is greater than or equal to 0.6 mm and less than or equal to 15 mm.

[0019] Optionally, the display module includes at least two second adhesive portions, which are respectively disposed on opposite sides of the flexible circuit board.

[0020] Optionally, the distance between one of the at least two second adhesive portions and the flexible circuit board is greater than or equal to the distance between the other of the at least two second adhesive portions and the flexible circuit board.

[0021] In the display module of this application embodiment, the edge banding is bonded to the flexible circuit board by a first adhesive part, and the edge banding is bonded to the printed circuit board by a second adhesive part. Since the first adhesive part and the second adhesive part are separated from each other, the edge of the first adhesive part is recessed inward relative to the edge of the flexible circuit board. When the edge banding tape is removed, the force on the flexible circuit board can be prevented from starting from the edge, and stress concentration can be prevented at the edge of the flexible circuit board. Therefore, it can be avoided that the flexible circuit board is torn off along with the edge banding and damages the display panel, thereby improving the rework yield of the display module.

[0022] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0030] Embodiments of this application provide a display module having a front side and a back side disposed opposite to each other in the thickness direction of the display module, and including a display panel, a flexible circuit board, a printed circuit board, and an edge-binding member. The display panel includes a bonding portion, the flexible circuit board is electrically connected to the bonding portion, and the printed circuit board is electrically connected to the flexible circuit board. The edge-binding member extends from the front side to the back side of the display module and covers the flexible circuit board and the printed circuit board. The display module also includes a first adhesive portion and a second adhesive portion. The edge-binding member is bonded to the flexible circuit board through the first adhesive portion, and the edge of the first adhesive portion is recessed inward relative to the edge of the flexible circuit board. The edge-binding member is bonded to the printed circuit board through the second adhesive portion, and the first adhesive portion and the second adhesive portion are separate from each other.

[0031] In the embodiments of this application, the edge banding is bonded to the flexible circuit board using a first adhesive portion, and the edge banding is bonded to the printed circuit board using a second adhesive portion. Since the first adhesive portion and the second adhesive portion are separated from each other, and the edge of the first adhesive portion is recessed inward relative to the edge of the flexible circuit board, when the edge banding tape is removed, the force on the flexible circuit board can be prevented from starting from the edge, thus preventing stress concentration on the flexible circuit board at the edge. Therefore, it can be avoided that the flexible circuit board is torn off along with the edge banding and damages the display panel, thereby improving the rework yield of the display module.

[0032] Combination Figure 1 and Figure 2 As shown, Figure 1 A top view of the display module provided in an embodiment of this application. Figure 2 The display module provided for the embodiments of this application is along Figure 1 The cross-sectional view along the A-A' direction shown indicates that the display module 100 has a front side and a back side that are disposed opposite to each other in the thickness direction of the display module. The front side of the display module refers to the light-emitting surface of the display module, and the back side of the display module refers to the side surface disposed opposite to the light-emitting surface.

[0033] The display module 100 includes a display panel 1, a flexible circuit board 2, a printed circuit board 3, and an edge-binding member 4. The display panel 1 includes a bonding portion 111. The flexible circuit board 2 is electrically connected to the bonding portion 111, and the printed circuit board 3 is electrically connected to the flexible circuit board 2. The edge-binding member 4 extends from the front to the back of the display module and covers the flexible circuit board 2 and the printed circuit board 3. The display module 100 also includes a first adhesive portion 5 and a second adhesive portion 6. The edge-binding member 4 is bonded to the flexible circuit board 2 through the first adhesive portion 5, and the edge of the first adhesive portion 5 is recessed inward relative to the edge of the flexible circuit board 2. The edge-binding member 4 is bonded to the printed circuit board 3 through the second adhesive portion 6, and the first adhesive portion 5 and the second adhesive portion 6 are separate from each other.

[0034] In this embodiment, the edge banding 4 is bonded to the flexible circuit board 2 using the first adhesive part 5, and the edge banding 4 is bonded to the printed circuit board 3 using the second adhesive part 6. Since the first adhesive part 5 and the second adhesive part 6 are separated from each other, and the edge of the first adhesive part 5 is recessed inward relative to the edge of the flexible circuit board 2, when the edge banding tape is removed, the force on the flexible circuit board 2 can be prevented from starting from the edge, thus preventing stress concentration at the edge of the flexible circuit board 2. Therefore, it can be avoided that the flexible circuit board 2 is torn off along with the edge banding 4, which would damage the display panel. This can improve the rework yield of the display module and reduce the production cost of the display module.

[0035] In some embodiments, combined with Figure 1 and Figure 2As shown, the display panel 1 is a liquid crystal display panel. The display panel 1 includes an array substrate 11, an opposing substrate 12, a liquid crystal layer (not shown in the figure), an upper polarizer 13, and a lower polarizer (not shown in the figure). The array substrate 11 and the opposing substrate 12 are disposed opposite to each other. The liquid crystal layer is disposed between the array substrate 11 and the opposing substrate 12. The upper polarizer 13 is disposed on the side of the opposing substrate 12 away from the array substrate 11, and the lower polarizer is disposed on the side of the array substrate 11 away from the opposing substrate 12.

[0036] In some embodiments, combined with Figure 1 and Figure 2 As shown, the array substrate 11 comprises a glass substrate and a driving circuit layer formed on the glass substrate. The array substrate 11 may include an array substrate main body 112 corresponding to the opposing substrate 12 and a bonding portion 111 extending beyond one end of the opposing substrate 12. The bonding portion 111 and the array substrate main body 112 are integrally formed. The bonding portion 111 is provided with multiple terminals, and the flexible circuit board 2 is bonded to the terminals of the bonding portion 111.

[0037] In some embodiments, such as Figure 2 As shown, the display module 100 also includes a backlight module 7, an optical film 8, a fixing member 10, and a conductive connector 101. The backlight module 7 is disposed on the light-incident side of the display panel 1, the optical film 8 is disposed between the backlight module 7 and the display panel 1, the display panel 1 is bonded to the backlight module 7 by the fixing member 10, and the backlight module 7 is electrically connected to the printed circuit board 3 by the conductive connector 101.

[0038] In some embodiments, the fastener 10 is an adhesive with stickiness on both sides, such as double-sided tape or foam adhesive.

[0039] In some embodiments, the conductive connector 101 is a flexible printed circuit board.

[0040] In some embodiments, such as Figure 2 As shown, the front side of the bonding portion 111 refers to the side surface of the bonding portion 111 closest to the light-emitting surface of the display panel, and the back side of the bonding portion 111 refers to the side surface of the bonding portion 111 closest to the backlight module 7. The edge-sealing member 4 extends from the front side of the bonding portion 111, bypassing the bonding portion 111, to the side surface of the backlight module 7 furthest from the display panel 1. The edge-sealing member 4 covers the bonding portion 111, the flexible circuit board 2, the printed circuit board 3, and the end of the backlight module 7 closest to the bonding portion 111, thus preventing light leakage from the display module.

[0041] In some embodiments, combined with Figures 1 to 3 As shown, Figure 3This is a partial schematic diagram of the flexible circuit board and printed circuit board in the display module provided in the embodiments of this application. The edge of the first adhesive part 5 is recessed inward relative to the edge of the flexible circuit board 2. There is a certain distance between the edge of the first adhesive part 5 and the edge of the flexible circuit board 2. The orthographic projection of the first adhesive part 5 on the reference plane is located within the orthographic projection of the flexible circuit board 2 on the reference plane. The reference plane is parallel to the light-emitting surface of the display panel.

[0042] In this embodiment, the edges of the first adhesive portion 5 are recessed inward by a certain distance relative to the edges of the flexible circuit board 2, so that the orthographic projection of the first adhesive portion 5 on the reference plane is located within the orthographic projection of the flexible circuit board 2 on the reference plane. This avoids the stress on the flexible circuit board 2 starting from the edges and prevents stress concentration at the edges of the flexible circuit board 2. Therefore, it can prevent the flexible circuit board 2 from being torn off along with the edge banding 4, which would damage the display panel. This can improve the rework yield of the display module and reduce the production cost of the display module.

[0043] In some embodiments, combined with Figure 2 and Figure 3 As shown, the flexible circuit board 2 includes a main body sub-part 21, a first connecting sub-part 22 located on the side of the main body sub-part 21 near the bonding part 111, and a second connecting sub-part 23 located on the side of the main body sub-part 21 away from the first connecting sub-part 22. The main body sub-part 21, the first connecting sub-part 22, and the second connecting sub-part 23 are integral structures and belong to different parts of the same flexible circuit board 2. Both the first connecting sub-part 22 and the second connecting sub-part 23 have multiple gold fingers. The first connecting sub-part 22 is partially disposed on the bonding part 111 and is bonded to the terminals of the bonding part 111 through the gold fingers. The second connecting sub-part 23 is disposed on the printed circuit board 3 and is bonded to the terminals on the printed circuit board 3 through the gold fingers.

[0044] The display module 100 also includes a third adhesive portion 9, which covers the bonding portion 111 and the first connecting portion 22. The third adhesive portion 9 is cured with ultraviolet light-curing adhesive, which can bond the first connecting portion 22 to the bonding portion 111 and prevent the first connecting portion 22 from falling off the bonding portion 111, thereby improving the stability of the connection between the first connecting portion 22 and the bonding portion 111.

[0045] In some embodiments, the inward distance between the side edge of the first adhesive portion 5 near the binding portion 111 and the corresponding side edge of the flexible circuit board 2 is equal to the inward distance between the other side edge of the first adhesive portion 5 and the corresponding side edge of the flexible circuit board 2.

[0046] Combination Figure 2 and Figure 3As shown, the second connecting sub-part 23 has multiple gold fingers, and the second connecting sub-part 23 is bonded to the terminals on the printed circuit board 3 through the gold fingers. The inward distance between the side edge of the first adhesive part 5 near the adhesive part 111 and the corresponding side edge of the flexible circuit board 2 is the first distance; the inward distance between the side edge of the first adhesive part 5 away from the adhesive part 111 and the corresponding side edge of the flexible circuit board 2 is the second distance d2; the inward distance between the edge of the first adhesive part 5 near one of the second adhesive parts 6 and the corresponding side edge of the flexible circuit board 2 is the third distance d3; and the inward distance between the edge of the first adhesive part 5 near the other of the second adhesive parts 6 and the corresponding side edge of the flexible circuit board 2 is the fourth distance d4. The first distance d1 is equal to the second distance d2, the third distance d3, and the fourth distance d4. When the first distance d1 is sufficiently large compared to the second distance d2, the third distance d3, and the fourth distance d4, the stability of the connection between the first connecting sub-part 22 and the adhesive part 111 can be improved.

[0047] In some embodiments, the distance between the edge of the first adhesive portion 5 and the edge of the flexible circuit board 2 is greater than or equal to 0.8 mm and less than or equal to 2 mm. For example, the distance between the edge of the first adhesive portion 5 and the corresponding side edge of the flexible circuit board 2 can be 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2 mm, etc. A distance between 0.8 and 2 mm is sufficient to improve the rework yield of the display module while simultaneously enhancing the stability of the connection between the first connecting sub-part 22 and the bonding portion 111.

[0048] In some embodiments, the inward distance between the side edge of the first adhesive portion 5 near the binding portion 111 and the corresponding side edge of the flexible circuit board 2 is greater than the inward distance between the other side edge of the first adhesive portion 5 and the corresponding side edge of the flexible circuit board 2.

[0049] Combination Figure 2 and Figure 3As shown, the inward distance between the edge of the first adhesive portion 5 near the bonding portion 111 and the corresponding edge of the flexible circuit board 2 is the first distance d1; the inward distance between the edge of the first adhesive portion 5 away from the bonding portion 111 and the corresponding edge of the flexible circuit board 2 is the second distance d2; the inward distance between the edge of the first adhesive portion 5 near one of the second adhesive portions 6 and the corresponding edge of the flexible circuit board 2 is the third distance d3; and the inward distance between the edge of the first adhesive portion 5 near the other of the second adhesive portions 6 and the corresponding edge of the flexible circuit board 2 is the fourth distance d4. The first distance d1 is greater than the second distance d2, the first distance d1 is greater than the third distance d3, and the first distance d1 is greater than the fourth distance d4. By increasing the inward distance between the edge of the first adhesive portion 5 near the bonding portion 111 and the corresponding edge of the flexible circuit board 2, sufficient space can be reserved on the first connecting sub-part 22 for applying the UV-curable adhesive required to form the third adhesive portion 9, thereby further improving the stability of the connection between the first connecting sub-part 22 and the bonding portion 111.

[0050] In some embodiments, the difference between the recessed distance between the side edge of the first adhesive portion 5 near the bonding portion 111 and the corresponding side edge of the flexible circuit board 2, and the recessed distance between the other side edge of the first adhesive portion 5 and the corresponding side edge of the flexible circuit board 2, is greater than or equal to 0.5 mm and less than or equal to 1 mm. Taking the first distance d1 and the second distance d2 as examples, the difference between the first distance d1 and the second distance d2 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm, etc. This can improve the rework yield of the display module while further improving the stability of the connection between the first connecting sub-part 22 and the bonding portion 111.

[0051] In some embodiments, such as Figure 3 As shown, the edge of the second adhesive part 6 is recessed inward relative to the edge of the printed circuit board 3, and the orthographic projection of the second adhesive part 6 on the reference plane is located within the orthographic projection of the printed circuit board 3 on the reference plane. This can prevent the edge of the second adhesive part 6 from exceeding the edge of the printed circuit board 3 due to manufacturing errors or assembly errors, thereby improving the production efficiency and yield of the display module.

[0052] In some embodiments, such as Figure 3 As shown, the second adhesive part 6 is spaced apart from the flexible circuit board 2, and there is a certain gap between the edge of the second adhesive part 6 and the edge of the flexible circuit board 2. This can prevent the second adhesive part 6 from being attached to the flexible circuit board 2 due to manufacturing errors or assembly errors.

[0053] In some embodiments, such as Figure 3As shown, the distance between the second adhesive part 6 and the flexible circuit board 2 is greater than or equal to 0.6 mm and less than or equal to 15 mm. For example, the distance between the second adhesive part 6 and the flexible circuit board 2 can be 0.6 mm, 0.8 mm, 1 mm, 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, 14 mm, or 15 mm, etc. It should be noted that, due to the limited area of ​​the printed circuit board 3, if the distance between the second adhesive part 6 and the flexible circuit board 2 is too large, it will compress the area of ​​the second adhesive part 6, reducing the adhesion between the edge banding 4 and the printed circuit board 3. This will cause the printed circuit board 3 and the flexible circuit board 2 to wobble and collide with other components, producing abnormal noise. If the distance between the second adhesive part 6 and the flexible circuit board 2 is too small, it will increase the probability that the second adhesive part 6 will adhere to the flexible circuit board 2 due to manufacturing or assembly errors.

[0054] This embodiment limits the distance between the second adhesive part 6 and the flexible circuit board 2 to between 0.6 mm and 15 mm. This ensures the stability of the connection between the edge banding 4 and the flexible circuit board 2 and the printed circuit board 3, prevents the printed circuit board 3 and the flexible circuit board 2 from shaking and colliding with other components, thus preventing abnormal noise. It also prevents the second adhesive part 6 from sticking to the flexible circuit board 2 due to manufacturing or assembly errors.

[0055] In some embodiments, the display module 100 includes at least two second adhesive portions 6, which are respectively disposed on opposite sides of the flexible circuit board 2. By designing the second adhesive portions 6 as a segmented structure and distributing the two second adhesive portions 6 on opposite sides of the flexible circuit board 2, it is possible to prevent the flexible circuit board from being torn off along with the edge banding and causing damage to the display panel, and to ensure the adhesion between the edge banding 4 and the printed circuit board 3, so as to prevent the printed circuit board 3 and the flexible circuit board 2 from shaking and colliding with other components, thus preventing abnormal noise.

[0056] In some embodiments, combined with Figure 1 and Figure 3 As shown, the display module 100 includes two flexible circuit boards 2 and one printed circuit board 3. The two flexible circuit boards 2 are spaced apart along the length of the printed circuit board 3. The display module 100 includes three second adhesive portions 6, which are disposed on one side of the flexible circuit board 2 or between two adjacent flexible circuit boards 2.

[0057] In some embodiments, the distance between one of the at least two second adhesive portions 6 and the flexible circuit board 2 is greater than or equal to the distance between the other of the at least two second adhesive portions 6 and the flexible circuit board 2.

[0058] Combination Figure 1 and Figure 3As shown, taking one of the flexible circuit boards 2 as an example, a second adhesive part 6 is provided on each side of the flexible circuit board 2. One of the second adhesive parts 6 has a fifth distance s1 with the flexible circuit board 2, and the other second adhesive part 6 has a sixth distance s2 with the flexible circuit board 2. The fifth distance s1 and the sixth distance s2 are equal.

[0059] In some other embodiments, the fifth distance s1 can be greater than the sixth distance s2; or the sixth distance s2 can be greater than the fifth distance s1. In this way, the stability of the connection between the edge banding 4 and the flexible circuit board 2 and the printed circuit board 3 can be ensured, and the printed circuit board 3 and the flexible circuit board 2 can be prevented from shaking and colliding with other components to produce abnormal noise. At the same time, it can also prevent the second adhesive part 6 from being attached to the flexible circuit board 2 due to manufacturing errors or assembly errors.

Please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a schematic diagram of a display device provided in an embodiment of this application.

The display module 100 can be any of the display modules provided in the above embodiments. The display device provided in the embodiments of this application can achieve the same technical effects as the display modules provided in any of the above embodiments, and will not be described in detail here.

[0061] The beneficial effects of the embodiments of this application are as follows: The embodiments of this application provide a display module and a display device. The display module includes a display panel, a flexible circuit board, a printed circuit board, an edge banding, a first adhesive part, and a second adhesive part. The display panel includes a bonding part, the flexible circuit board is electrically connected to the bonding part, and the printed circuit board is electrically connected to the flexible circuit board. The edge banding extends from the front side of the display module to the back side of the display module and covers the flexible circuit board and the printed circuit board. The edge banding is bonded to the flexible circuit board using the first adhesive part, and to the printed circuit board using the second adhesive part. Since the first adhesive part and the second adhesive part are separated from each other, the edge of the first adhesive part is recessed inward relative to the edge of the flexible circuit board. When the edge banding tape is removed, the force on the flexible circuit board can be prevented from starting from the edge, and stress concentration can be prevented at the edge of the flexible circuit board. Therefore, it can be avoided that the flexible circuit board is torn off along with the edge banding and damages the display panel, thereby improving the rework yield of the display module.
