Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display module and a display device. Background Art

[0002] Static electricity is an objective natural phenomenon that is generated in many ways, such as contact, friction, and induction between electrical appliances. Static electricity has the characteristics of long-term accumulation, high voltage, low power, small current, and short action time. The human body's own movements or contact, separation, friction, or induction with other objects can generate thousands or even tens of thousands of volts of static electricity. Triboelectric charging and human body static electricity are two major hazards in the electronics industry, often causing unstable operation or even damage to electronic and electrical products.

[0003] At present, electrostatic foam is usually set on the grounded conductive tape in the display module, and the middle frame is grounded through the electrostatic foam and the conductive tape to release the accumulated charge on the middle frame. Since the conductive tape is usually a double-sided tape structure, conductive glue is set on both sides of the conductive fabric of the conductive tape, and the conductive foam itself has a layer of conductive glue. When the conductive glue of the conductive tape and the conductive glue of the conductive foam are poorly bonded, the impedance between the conductive tape and the conductive glue is too high, so that the charge on the middle frame cannot be released, resulting in electrostatic damage to the display module, causing the yield and quality of the display module to decrease.

[0004] Therefore, it is necessary to provide a display module and a display device to improve this defect. Summary of the invention

[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0055] An embodiment of the present application provides a display module, which includes a display panel, a middle frame, a conductive buffer and a conductive tape. The display panel is arranged on the middle frame, the conductive buffer is in contact with the middle frame, the surface of the conductive buffer away from the middle frame is sticky, and the conductive tape includes a first sticky layer and a non-sticky layer, both of which are conductive, the first sticky layer is bonded to the display panel, the non-sticky layer is bonded to the surface of the conductive buffer away from the middle frame, and the conductive tape is grounded.

[0056] In an embodiment of the present application, the first adhesive layer of the conductive tape is bonded to the display panel, and the non-adhesive layer of the conductive tape is directly bonded to the sticky surface of the conductive buffer component away from the middle frame, without the need for additional conductive adhesive to bond the conductive tape to the conductive buffer component. This can reduce the risk of poor bonding between the conductive tape and the conductive buffer component, and reduce the impedance between the conductive tape and the conductive buffer component, ensuring that the charge on the middle frame can be released through the conductive buffer component and the grounding of the conductive tape, thereby reducing the risk of electrostatic damage to the display module, thereby improving the yield and quality of the display module.

[0057] See also Figure 1 and Figure 2 , Figure 1 A bottom view of the first display module provided in the embodiment of the present application, Figure 2This is a partial enlarged schematic diagram of the first display module provided in the embodiment of the present application. The display module 100 includes a display panel 1. The display panel 1 includes a main body 11 and a binding portion 12. The binding portion 12 is connected to one end of the main body 11. In the final product structure, the binding portion 12 is configured to be bent to the back of the main body 11. The front of the main body 11 is the display surface of the display panel 1, and the back of the main body 11 is the side opposite to the front of the main body 11.

[0058] In some embodiments, see Figure 3 , Figure 3 The cross-sectional view of the first display module along the AA′ direction provided in the embodiment of the present application, the display panel 1 further includes a bending portion 13 , the bending portion 13 is connected between the main body portion 11 and the binding portion 12 , and the bending portion 13 is configured in a bending shape.

[0059] In some embodiments, see Figure 3 The outer surface of the bending portion 13 is covered with a protective layer 9, and the protective layer 9 is used to maintain the shape of the bending portion 13 and prevent the bending portion 13 from being damaged.

[0060] See also Figures 1 to 3 The display module 100 further includes a middle frame 2, a conductive buffer 3 and a conductive tape 4. The display panel 1 is disposed on the middle frame 2. The conductive buffer 3 is in contact with the middle frame 2. The surface of the conductive buffer 3 away from the middle frame 2 is sticky. The conductive tape 4 includes a first sticky layer 401 and a non-sticky layer 402. The non-sticky layer 402 is disposed on the first sticky layer 401. The first sticky layer 401 and the non-sticky layer 402 are both conductive. The first sticky layer 401 is bonded to the display panel 1. The non-sticky layer 402 is bonded to the surface of the conductive buffer 3 away from the middle frame 2. The conductive tape 4 is grounded. The middle frame 2 is electrically connected to the conductive tape 4 through the conductive buffer 3. Since the conductive tape 4 is grounded, the charges accumulated on the middle frame 2 can be released through the conductive tape 4.

[0061] In this embodiment, the surface of the conductive buffer 3 away from the middle frame 2 is sticky, and the non-sticky layer 402 of the conductive tape 4 is directly bonded to the sticky surface of the conductive buffer 3 away from the middle frame 2, so as to achieve the fixation and electrical connection between the conductive buffer 3 and the conductive tape 4. Therefore, there is no need to set a conductive adhesive on the surface of the non-sticky layer 402 close to the conductive buffer 3, which can reduce the risk of poor bonding between the conductive buffer 3 and the conductive tape 4, and reduce the impedance between the conductive buffer 3 and the conductive tape 4, ensuring that the charge on the middle frame 2 can be released through the conductive buffer 3 and the conductive tape 4 to the ground, reducing the risk of electrostatic damage to the display module, thereby improving the yield and quality of the display module.

[0062] In some embodiments, see Figure 3The material of the first adhesive layer 401 is conductive adhesive, which includes adhesive material and conductive particles (not shown in the figure) distributed in the adhesive material. The non-adhesive layer 402 is conductive fabric. Both the first adhesive layer 401 and the non-adhesive layer 402 are conductive.

[0063] In some embodiments, see Figure 3 The conductive buffer 3 includes a conductive main body 301 and a conductive adhesive part 302. The conductive main body 301 is disposed on the conductive adhesive part 302. The surface of the conductive main body 301 away from the conductive adhesive part 302 is in contact with the middle frame 2. The surface of the conductive adhesive part 302 away from the conductive main body 301 is directly bonded to the non-adhesive layer 402 of the conductive tape 4. The conductive main body 301 has a certain elastic deformation ability. The middle frame 2 is directly pressed on the surface of the conductive main body 301 away from the conductive adhesive part 302, thereby achieving the fixing of the conductive buffer 3.

[0064] In some embodiments, the conductive body portion 301 is made of conductive foam, and the conductive adhesive portion 302 is made of conductive glue.

[0065] In some embodiments, the combination and Figure 2 and Figure 4 As shown, Figure 4 The first display module provided in the embodiment of the present application is a partially enlarged schematic diagram after the packaging tape is removed. The display module 100 also includes an integrated circuit chip 5 and a packaging tape 6. The integrated circuit chip 5 is arranged on the binding portion 12. The packaging tape 6 is at least bonded to the non-adhesive layer 402. In the film thickness direction of the packaging tape 6, the packaging tape 6 covers the integrated circuit chip 5.

[0066] In some embodiments, see Figures 1 to 4 The side where the packaging tape 6 is bonded to the non-adhesive layer 402 is conductive, the conductive adhesive portion 302 of the conductive buffer 3 is bonded to the non-adhesive layer 402, the conductive buffer 3 is electrically connected to the packaging tape 6 through the non-adhesive layer 402 of the conductive tape 4, and the packaging tape 6 is grounded, that is, the middle frame 2 is grounded through the conductive buffer 3, the conductive tape 4 and the packaging tape 6.

[0067] In some embodiments, see Figure 2 The display module 100 further includes a flexible circuit board 7 and a heat dissipation support layer 8. The heat dissipation support layer 8 is disposed on the back of the main body 11. The flexible circuit board 7 is bound and connected to the binding portion 12. The flexible circuit board 7 is in contact with the heat dissipation support layer 8. The packaging tape 6 is bonded to the flexible circuit board 7. The packaging tape 6 is in contact with the metal pattern exposed on the surface of the flexible circuit board 7. The heat dissipation support layer 8 is made of metal. The heat dissipation support layer 8 can not only provide support and heat dissipation, but also provide grounding, so that the middle frame 2 can be grounded through the conductive buffer 3, the conductive tape 4, the packaging tape 6, the flexible circuit board 7 and the heat dissipation support layer 8.

[0068] In some embodiments, see Figure 4 and Figure 5 , Figure 5 A schematic diagram of the structure of a conductive tape in a first display module provided in an embodiment of the present application, wherein the conductive buffer 3 includes a first sub-conductive buffer 31 and a second sub-conductive buffer 32, wherein the first sub-conductive buffer 31 and the second sub-conductive buffer 32 are spaced apart from each other, and the first sub-conductive buffer 31 and the second sub-conductive buffer 32 are respectively disposed at opposite ends of a binding portion 12, and the first sub-conductive buffer 31 and the second sub-conductive buffer 32 have the same structure, and are both composed of a conductive main body portion 301 and a conductive adhesive portion 302.

[0069] See also Figure 4 and Figure 5 The conductive tape 4 includes a first sub-conductive tape 41 and a second sub-conductive tape 42. The first sub-conductive tape 41 and the second sub-conductive tape 42 are arranged at intervals. The first sub-conductive tape 41 is arranged corresponding to the first sub-conductive buffer 31, and the second sub-conductive tape 42 is arranged corresponding to the second sub-conductive buffer 32. The first sub-conductive tape 41 and the second sub-conductive tape 42 have the same structure, and are both composed of a first adhesive layer 401 and a non-adhesive layer 402.

[0070] See also Figure 4 and Figure 5 The non-adhesive layer 402 of the first sub-conductive tape 41 is bonded to the conductive adhesive portion 302 of the first sub-conductive buffer 31 , and the non-adhesive layer 402 of the first sub-conductive tape 41 is also bonded to the packaging tape 6 . The non-adhesive layer 402 of the second sub-conductive tape 42 is bonded to the conductive adhesive portion 302 of the second sub-conductive buffer 32. The non-adhesive layer 402 of the second sub-conductive tape 42 is also bonded to the packaging tape 6. The side of the packaging tape 6 bonded to the non-adhesive layer 402 is conductive. The first sub-conductive buffer 31 and the second sub-conductive buffer 32 can be connected through the first sub-conductive tape 41, the packaging tape 6 and the second sub-conductive tape 42. Since the conductive tape 4 only has the first adhesive layer 401 and the non-adhesive layer 402, the non-adhesive layer 402 is directly bonded to the conductive adhesive portion 302 of the conductive buffer 3 without an additional layer of conductive adhesive. Therefore, the impedance between the first sub-conductive buffer 31 and the second sub-conductive buffer 32 can be reduced, ensuring that the charge on the middle frame can be released through the conductive buffer and the conductive tape grounding, reducing the risk of electrostatic damage to the display module, thereby improving the yield and quality of the display module.

[0071] In some embodiments, see Figures 2 to 5The packaging tape 6 includes a second adhesive layer 601, a conductive layer 602 and an insulating layer 603 which are stacked. The conductive layer 602 is arranged on the surface of the second adhesive layer 601 away from the conductive tape 4. The insulating layer 603 is arranged on the surface of the conductive layer 602 away from the second adhesive layer 601. Part of the second adhesive layer 601 is bonded to the non-adhesive layer 402, and the other part is bonded to the binding part 12 and the integrated circuit chip 5. The second adhesive layer 601 is conductive.

[0072] See also Figures 2 to 5 The non-adhesive layer 402 of the first sub-conductive tape 41 and the non-adhesive layer 402 of the second sub-conductive tape 42 are both bonded to the same second adhesive layer 601, the first sub-conductive tape 41 and the second sub-conductive tape 42 are connected through the second adhesive layer 601 and the conductive layer 602, and the first sub-conductive buffer 31 and the second sub-conductive buffer 32 can be connected through the first sub-conductive tape 41, the packaging tape 6 and the second sub-conductive tape 42, so that the middle frame 2 can be grounded through the conductive buffer 3, the conductive tape 4, the packaging tape 6, the flexible circuit board 7 and the heat dissipation support layer 8. The integrated circuit chip 5 can also be grounded through the packaging tape 6 and the flexible circuit board 7, thereby reducing the risk of electrostatic damage to the integrated circuit chip 5.

[0073] In some embodiments, the material of the second adhesive layer 601 is conductive adhesive.

[0074] In some embodiments, see Figure 3 The display module 100 also includes a first back plate 101, a second back plate 102 and a composite support layer 103. The first back plate 101 is arranged on the back side of the main body 11, the heat dissipation support layer 8 is arranged on the side of the first back plate 101 away from the main body 11, the second back plate 102 is arranged on the back side of the binding part 12, and the composite support layer 103 is arranged between the second back plate 102 and the heat dissipation support layer 8.

[0075] In some embodiments, see Figures 6 to 8 , Figure 6 A partial enlarged schematic diagram of the second display module provided in an embodiment of the present application after the packaging tape is removed, Figure 7 A cross-sectional view of a second display module provided by an embodiment of the present application along the BB' direction, Figure 8 This is a schematic diagram of the structure of the conductive tape in the second display module provided in an embodiment of the present application. The structure of the display module provided in this embodiment is substantially the same as the structure of the first display module provided in the above embodiment, with the difference that: the first sub-conductive buffer 31 and the second sub-conductive buffer 32 are bonded to the same non-adhesive layer 402, and the side where the packaging tape 6 is bonded to the non-adhesive layer 402 is insulated.

[0076] See also Figures 6 to 8The conductive tape 4 is an integrated structure and is arranged on the entire surface. The first sub-conductive buffer 31 and the second sub-conductive buffer 32 are both adhered to the non-adhesive layer 402 of the same conductive tape 4. The first sub-conductive buffer 31 and the second sub-conductive buffer 32 are directly connected through the non-adhesive layer 402 of the conductive tape 4. In this way, the impedance between the first sub-conductive buffer 31 and the second sub-conductive buffer 32 can be further reduced, thereby further reducing the risk of electrostatic damage to the display module, thereby improving the yield and quality of the display module.

[0077] See also Figure 8 The packaging tape 6 includes a second adhesive layer 601 and an insulating layer 603. The second adhesive layer 601 is bonded to the non-adhesive layer 402, and the second adhesive layer 601 is insulated. The insulating layer 603 is arranged on the surface of the second adhesive layer 601 away from the conductive tape 4. The orthographic projection of the packaging tape 6 on the conductive tape 4 is located inside the conductive tape 4. The size of the packaging tape 6 can be the same as that of the conductive tape 4, or smaller than that of the conductive tape 4.

[0078] In this embodiment, the packaging tape 6 is not conductive but only insulating. By covering the packaging tape 6 on the surface of the conductive tape 4 away from the display panel 1, on the one hand, the conductive tape 4 can be isolated from other components in the display module to prevent other components from contacting the conductive tape 4 and causing a short circuit. On the other hand, the static electricity protection capability of the display module can be improved.

[0079] In some embodiments, see Figure 8 The packaging tape 6 has an opening 61, and the opening 61 penetrates the second adhesive layer 601 and the insulating layer 603. The conductive buffer 3 is arranged in the opening 61, and the conductive buffer 3 is arranged at a distance from the inner wall of the opening 61. By arranging the opening 61 on the packaging tape 6, the conductive main body 301 of the conductive buffer 3 is exposed by the opening 61, so that the conductive main body 301 of the conductive buffer 3 is convenient to contact with the middle frame 2, so as to ensure that the middle frame 2 can be grounded through the conductive buffer 3, thereby reducing the risk of electrostatic damage to the display module, thereby improving the yield and quality of the display module.

[0080] In some embodiments, the distance d1 between the conductive buffer 3 and the inner wall of the opening 61 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm. Due to the precision of the assembly process, if the size of the opening 61 is too small, when attaching the packaging tape 6, if the offset of the packaging tape 6 is too large, the packaging tape 6 will cover the conductive buffer 3, resulting in the middle frame 2 being unable to contact the conductive buffer 3, causing the middle frame 2 to be unable to be grounded through the conductive buffer 3, resulting in an increased risk of electrostatic damage to the display module. By making the distance d1 between the conductive buffer 3 and the inner wall of the opening 61 greater than or equal to 0.3 mm and less than or equal to 0.5 mm, it can be ensured that the conductive buffer 3 can be assembled into the opening 61, thereby ensuring that the middle frame 2 can be grounded through the conductive buffer 3, thereby reducing the risk of electrostatic damage to the display module, thereby improving the yield and quality of the display module.

[0081] In some embodiments, see Figures 6 to 8 In the film thickness direction of the conductive tape 4, the conductive tape 4 covers the integrated circuit chip 5 and partially covers the flexible circuit board 7. The first adhesive layer 401 is partially bonded to the flexible circuit board 7. The first adhesive layer 401 contacts the exposed metal pattern on the surface of the flexible circuit board 7. The middle frame 2 can be grounded through the conductive buffer 3, the conductive tape 4, the flexible circuit board 7 and the supporting layer 8.

[0082] Beneficial effects of the embodiments of the present application: In the display module of the present embodiment, by bonding the first adhesive layer to the display panel and directly bonding the non-adhesive layer to the sticky surface of the conductive buffer away from the middle frame, there is no need to add additional conductive adhesive to bond the conductive tape to the conductive buffer. This can reduce the risk of poor bonding between the conductive tape and the conductive buffer, and reduce the impedance between the conductive tape and the conductive buffer, ensuring that the charge on the middle frame can be released through the conductive buffer and the conductive tape to the ground, thereby reducing the risk of electrostatic damage to the display module, thereby improving the yield and quality of the display module.
