[0051] In one embodiment, this embodiment provides a display module 1, which includes a packaging structure 30, a display panel 10 and a composite support layer 20, wherein the packaging structure 30 is located on the light emitting side of the display panel 10, and the display panel 10 includes but is not limited to an organic light emitting diode display panel 10.

[0054] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ;in, Figure 3 A first partial top view schematic diagram of a display module provided in an embodiment of the present application; Figure 4 A schematic diagram of the first structure of the protective member provided in the embodiment of the present application; Figure 5 The embodiments of the present application provide Figure 4 The enlarged schematic diagram of point A in the middle;

[0055] Figure 6 An exploded schematic diagram of a protective member provided in an embodiment of the present application; Figure 7 It is a schematic diagram of the partial structure of the protective member in the related art; it should be noted that, Figure 3 The provided top view schematic diagram shows the structural layout of the display panel at the binding portion and depicts the specific structure of the protective member in detail.

[0056] In one embodiment, the display module 1 also includes a driving chip 100 and a protective member 110. The driving chip 100 is disposed on a side of the binding portion 12 away from the planar portion 11. The driving chip 100 is connected to the binding portion 12. The protective member 110 is disposed on a side of the binding portion 12 away from the planar portion 11. The protective member 110 includes a protective tape 1101 and a grounding portion 1102.

[0057] The grounding portion 1102 is disposed on at least one side of the driving chip 100 along the width direction of the display panel 10. The width direction of the display panel 10 may be Figure 1 and Figure 3 In the X direction, the length direction of the display panel 10 may be Figure 1 and Figure 3 In the Y direction, the grounding portion 1102 can be arranged on both sides of the driver chip 100 along the width direction of the display panel 10, and the grounding portion 1102 is used to realize the grounding function; the protective tape 1101 extends from the end of the binding portion 12 close to the bending portion 13 to the end of the binding portion 12 away from the bending portion 13 to cover the driver chip 100, thereby providing mechanical protection and environmental isolation for the driver chip 100, which can effectively prevent dust and moisture from intruding into the driver chip 100 and avoid external mechanical damage, thereby improving the reliability and service life of the driver chip 100.

[0058] The protective tape 1101 can adopt a single-sided insulating conductive film structure design; wherein, the side of the protective tape 1101 away from the binding part 12 is an insulating film, and the side of the protective tape 1101 close to the binding part 12 is a conductive film, so that the protective tape 1101 can be used as an electromagnetic shielding film to cover the side of the driver chip 100 away from the binding part 12, providing electromagnetic shielding protection for the driver chip 100, which can effectively suppress the influence of external electromagnetic interference on the driver chip 100, and can also prevent the display panel 10 from abnormal display due to interference, thereby ensuring the stability and reliability of the display module 1.

[0059] Furthermore, the edge of the protective tape 1101 is arranged along the outer closed loop of the grounding portion 1102, so that the protective tape 1101 can form a closed loop structure around the grounding portion 1102, thereby ensuring that the protective tape 1101 achieves a more stable and uniform fitting effect around the grounding portion 1102.

[0060] Please continue to combine Figures 1 to 7In one embodiment, the protective tape 1101 includes a tape body 11012 and a connecting section 11013, and the tape body 11012 is arranged around a portion of the periphery of the grounding portion 1102; the connecting section 11013 is arranged on one side of the grounding portion 1102 along the width direction of the display panel 10, and the connecting section 11013 extends along the length direction of the display panel 10, and the connecting section 11013 and the tape body 11012 are connected to each other; wherein, the material of the tape body 11012 is the same as that of the connecting section 11013, and the tape body 11012 and the connecting section 11013 are arranged in a closed loop along the periphery of the grounding portion 1102, and the connecting section 11013 and the tape body 11012 can be integrally formed.

[0061] like Figure 7 As shown, in the related art, the edge of the protective tape 111 usually fails to form a closed loop along the periphery of the grounding portion 112, but is only arranged around the periphery of a portion of the grounding portion 112 to form a relatively small connecting portion 1110 on the periphery of the grounding portion 112. Due to the small area of ​​the connecting portion 1110, the protective tape 111 may lack sufficient adhesion in local areas, making it difficult to achieve stable fitting; in addition, when external stress (such as bending, stretching or temperature changes) acts on the protective tape 111, the connecting portion 1110 is prone to produce a large stress concentration, resulting in problems such as warping and wrinkling of the protective tape 111 at the connecting portion.

[0062] It can be understood that in this embodiment, the edge of the protective tape 1101 is arranged as a closed loop structure along the periphery of the grounding portion 1102. Specifically, the tape body 11012 and the connecting section 11013 are arranged in a closed loop along the periphery of the grounding portion 1102, thereby effectively increasing the bonding area of ​​the protective tape 1101 and improving its bonding stability. Compared with the protective tape 111 in the related art, which may have problems such as wrinkles and warping due to insufficient bonding area or external force during the bonding process with the driver chip 100, the closed loop design of the protective tape 1101 in this embodiment can avoid these defects.

[0063] Please continue to combine Figures 1 to 7In one embodiment, the protective member 110 also includes an electrical connector 1103, which is disposed between the binding portion 12 and the protective tape 1101, wherein one end of the electrical connector 1103 is connected to the first grounding terminal of the binding portion 12, and the other end of the electrical connector 1103 is connected to the grounding portion 1102, wherein the protective tape 1101 covers at least a portion of the electrical connector 1103, so that the protective tape 1101 can connect the driver chip 100 and the electrical connector 1103, and then form a reliable grounding path through the electrical connector 1103 and the grounding portion 1102, thereby ensuring that the electrical signal can be transmitted stably; wherein the grounding portion 1102 can be connected to the housing or middle frame of the display device to achieve grounding.

[0064] At the same time, by covering at least a portion of the electrical connector 1103 with the protective tape 1101, the electrical connector 1103 can be effectively prevented from being exposed to the external environment and from being interfered with by external forces or mechanical damage. In addition, the side of the electrical connector 1103 close to the protective tape 1101 is a uniform and flat surface, and the protective tape 1101 is adhered to this surface, thereby increasing the adhesion stability of the protective tape 1101 on the surface of the binding portion 12, thereby reducing the probability of wrinkles and warping, and further enhancing the overall performance of the display module 1 and the reliability of long-term use.

[0065] Please continue Figures 1 to 7 In one embodiment, the grounding portion 1102 is arranged corresponding to the electrical connector 1103, and the orthographic projection of the grounding portion 1102 on the binding portion 12 is located within the orthographic projection of the electrical connector 1103 on the binding portion 12, thereby ensuring that the relative position relationship between the grounding portion 1102 and the electrical connector 1103 is more stable and accurate, avoiding poor grounding and signal interference problems caused by the offset of the grounding portion 1102.

[0066] The protective tape 1101 is provided with a first opening 1100 corresponding to the grounding portion 1102, and the inner wall of the first opening 1100 is spaced apart from the grounding portion 1102. The first opening 1100 provides additional space for the setting of the grounding portion 1102. The spacing setting can avoid contact between the protective tape 1101 and the grounding portion 1102, thereby reducing electrical interference between the protective tape 1101 and the grounding portion 1102, ensuring that the function of the grounding portion 1102 is not affected by the protective tape 1101; at the same time, the risk of wrinkling and warping of the protective tape 1101 during the bonding process is reduced.

[0067] It is understandable that if the distance between the inner wall of the first opening 1100 and the grounding portion 1102 is too small, the protective tape 1101 may be in direct contact with the grounding portion 1102, thereby affecting the normal function of the grounding portion 1102 and causing the problem of unstable electrical signal conduction. If the distance is too large, the protective tape 1101 may be unstable when attached to the display panel 10, resulting in warping or wrinkling. The spacing between 1102 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm, which can ensure that the protective tape 1101 is more firmly attached to the binding portion 12 of the display panel 10, reducing defects caused by poor fitting; in addition, the appropriate spacing can also enhance the mechanical and electrical isolation between the protective tape 1101 and the grounding portion 1102, improve the stability and durability between the protective tape 1101 and the grounding portion 1102, and reduce damage or failure caused by external forces or environmental changes.

[0068] Further, the electrical connector 1103 includes a first connector 11031 and a second connector 11032 that are connected to each other, and the first connector 11031 is located inside the first opening 1100, and the second connector 11032 is located outside the first opening 1100; wherein, the first connector 11031 is arranged corresponding to the grounding portion 1102, and the orthographic projection of the grounding portion 1102 on the binding portion 12 is located within the orthographic projection of the first connector 11031 on the binding portion 12.

[0069] The orthographic projection of the second connecting sub-component 11032 on the binding portion 12 is located within the orthographic projection of the protective tape 1101 on the binding portion 12, and the edge shape of the second sub-part away from the first opening 1100 matches the edge shape of the protective tape 1101 away from the first opening 1100, thereby ensuring a good fit between the electrical connector 1103 and the protective tape 1101; at the same time, the connection stability between the grounding portion 1102 and the electrical connector 1103 is enhanced.

[0070] It should be noted that in the related art, before the protective member is bonded to the display panel, a release film is usually affixed to its sticky side to prevent the protective member from sticking or being contaminated when not in use; however, since the edge of the protective tape usually fails to form a closed loop along the periphery of the grounding portion, a portion of the electrical connector is not covered by the protective tape; when the release film is torn off, these uncovered areas are easily lifted up, causing the electrical connector to be torn, wrinkled or deflected.

[0071] It can be understood that, in this embodiment, by setting the edge of the protective tape 1101 as a closed-loop structure along the periphery of the grounding portion 1102, the orthographic projection of the second connecting sub-component 11032 on the binding portion 12 is located within the orthographic projection of the protective tape 1101 on the binding portion 12, thereby effectively increasing the fitting area between the protective tape 1101 and the electrical connector 1103, thereby ensuring the close fit between the electrical connector 1103 and the protective tape 1101 and improving the overall stability and protection effect.

[0072] Please continue to combine Figures 1 to 7 In one embodiment, the display module 1 further comprises a supporting insulating portion 1104 disposed on a side of the protective tape 1101 away from the binding portion 12, and the supporting insulating portion 1104 is located between the driver chip 100 and the bending portion 13; wherein one end of the supporting insulating portion 1104 is spaced apart from the driver chip 100, and the other end of the supporting insulating portion 1104 is spaced apart from the bending portion 13, thereby providing physical support through the supporting insulating portion 1104, thereby reducing the impact of mechanical shock on the driver chip 100.

[0073] In the related art, a middle frame is usually used to fix the display module, and the middle frame includes a bottom frame and a side frame arranged around the bottom frame, the bottom frame is arranged on the side of the binding portion away from the planar portion, and the side frame is arranged on one side of the bending portion, thereby effectively avoiding deformation or damage of the display panel caused by external force; however, due to the lack of support in the area between the driving chip and the bottom frame, the area may be locally dented or compressed and deformed when subjected to external force, thereby affecting the reliability and stability of the display module.

[0074] It can be understood that in this embodiment, a supporting insulating portion 1104 is provided on the side of the protective tape 1101 away from the binding portion 12. The supporting insulating portion 1104 can be attached to the bottom frame of the display device through an adhesive layer, thereby enhancing the connection stability between the display module 1 and the middle frame, dispersing the mechanical stress acting on the protective tape 1101, thereby buffering the protective tape 1101, reducing the direct impact of mechanical shock on the driver chip 100, and further improving the stability of the display module 1.

[0075] Furthermore, the supporting insulating portion 1104 may be insulating foam, which has excellent flexibility, light weight and good buffering performance. When the display module 1 is subjected to external force, the insulating foam material can effectively absorb the impact energy and reduce the external force on the driver chip 100 and its surrounding areas, thereby avoiding damage to the driver chip 100 due to the force; the grounding portion 1102 may be conductive foam, which can not only conduct away static electricity but also play a buffering and protective role. The grounding portion 1102 can be attached to the electrical connector 1103 through an adhesive layer; in other embodiments, the grounding portion 1102 and the supporting insulating portion 1104 may also be other conductive materials, which are not limited here.

[0076] In the width direction of the display panel 10, the edge of the supporting insulating part 1104 is flush with the inner wall of the first opening 1100 close to the edge of the binding part 12, thereby ensuring the stable fit between the supporting insulating part 1104 and the protective tape 1101 while preventing the supporting insulating part 1104 from excessively extending to the grounding part 1102 and affecting the electrical connection performance of the grounding part 1102, thereby improving the reliability of the display module 1.

[0077] Please continue to combine Figures 1 to 7 In one embodiment, the display module 1 also includes a circuit board 120 disposed at an end of the binding portion 12 away from the bending portion 13, the circuit board 120 includes a circuit board body 1201 and an extension portion 1202, the circuit board body 1201 is electrically connected to the binding portion 12, the extension portion 1202 is connected to the circuit board body 1201, the extension portion 1202 extends in a direction away from the circuit board body 1201, and the extension direction of the extension portion 1202 is parallel to the width direction of the display panel 10, so that the circuit board 120 realizes a special-shaped structural design, which can adapt to the limited space layout in the display module 1, avoids the circuit board 120 from occupying too much space or interfering with the arrangement of other components during installation, and further improves the lightness and reliability of the book search display module 1.

[0078] The protective tape 1101 covers at least a portion of the circuit board body 1201; wherein, the edge of the circuit board body 1201 has a second grounding terminal, and the second grounding terminal can be located on a side of the circuit board body 1201 close to the driving chip 100, the protective tape 1101 covers the second grounding terminal, and the grounding portion 1102 is arranged non-overlappingly with the second grounding terminal, so that the protective tape 1101 can be connected to the second grounding terminal, the first grounding terminal and the driving chip 100, and then a reliable grounding path is formed with the grounding portion 1102 through the electrical connector 1103, thereby ensuring that the electrical signal can be transmitted stably, further improving the electrical performance and reliability of the display module 1; in addition, the grounding portion 1102 can be grounded by being connected to the shell or middle frame of the display device, thereby enhancing the electromagnetic compatibility of the entire display module 1 and reducing the risk of interference.

[0079] The protective tape 1101 and the extension portion 1202 are arranged non-overlappingly; it is understandable that when the area of ​​the extension portion 1202 is small, the fitting area of ​​the protective tape 1101 and the extension portion 1202 is small, and during the fitting process, the protective tape 1101 may not be firmly adhered to the extension portion 1202, thereby causing wrinkles, warping, etc. to appear in the fitting portion of the protective tape 1101 and the extension portion 1202; this embodiment can improve the fitting stability and reliability of the protective tape 1101 by arranging the protective tape 1101 and the extension portion 1202 non-overlappingly; at the same time, it can also simplify the cutting and fitting process of the protective tape 1101, which helps to improve the assembly efficiency of the display module 1 and reduce production complexity and manufacturing costs.

[0081] In one embodiment, the protective tape 1101 has an extension section 11011, which covers at least a portion of the extension portion 1202 and contacts the side of the composite supporting layer 20 away from the first backplane 40, thereby ensuring a firm fit between the protective tape 1101 and the extension portion 1202, avoiding the problem of poor fit between the protective tape 1101 and the extension portion 1202 due to a small fitting area, thereby preventing the occurrence of wrinkles, warping, etc. in the fitting portion between the protective tape 1101 and the extension portion 1202.

[0082] Specifically, by setting the protective tape 1101 to have an extension section 11011, the extension section 11011 can extend from one side of the protective tape 1101 to the side close to the composite supporting layer 20, and contact the side of the composite supporting layer 20 away from the first back panel 40, thereby effectively increasing the bonding area of ​​the protective tape 1101, improving the bonding stability of the protective tape 1101, and ensuring the reliability and durability of the protective tape 1101 in the display module 1.

[0083] Furthermore, the extension segment 11011 includes a first sub-segment 110111 and a second sub-segment 110112 connected to each other, the first sub-segment 110111 extends along the first direction, the second sub-segment 110112 extends along the second direction, and there is a preset angle between the first direction and the second direction, and the preset angle can be 90 degrees. The first direction can be the width direction of the display panel 10, that is, the X direction; the second direction can be the length direction of the display panel 10, that is, the Y direction.

[0084] The orthographic projection of the first sub-segment 110111 on the supporting portion is located within the orthographic projection of the extension portion 1202 on the supporting portion, thereby ensuring that the first sub-segment 110111 and the extension portion 1202 fit together, providing mechanical protection and environmental isolation for the extension portion 1202, and effectively preventing dust and moisture from intruding into the extension portion 1202 while avoiding external mechanical damage, thereby improving the reliability and service life of the circuit board 120.

[0085] At least part of the orthographic projection of the second sub-segment 110112 on the support portion does not overlap with the orthographic projection of the extension portion 1202 on the support portion, and at least part of the second sub-segment 110112 is connected to the support portion, thereby enhancing the fitting stability of the extension segment 11011 and avoiding the problem of poor fitting between the first sub-segment 110111 and the extension portion 1202 due to the smaller fitting area between the first sub-segment 110111 and the extension portion 1202.

[0086] It can be understood that, in this embodiment, by configuring the extension segment 11011 to include a first sub-segment 110111 and a second sub-segment 110112 that are connected, the layout and structure of the protective tape 1101 are optimized, thereby improving its reliability in the display module 1.

[0087] Furthermore, the display module 1 also includes a functional film layer 80 arranged on the light-emitting side of the display panel 10 and a protective layer 130 located on one side of the bending portion 13, the functional film layer 80 is located between the packaging structure 30 and the display panel 10, the functional film layer 80 includes but is not limited to a polarizer 81 located on the light-emitting side of the display panel 10, and the functional film layer 80 covers the planar portion 11 in a direction perpendicular to the display panel 10; the protective layer 130 can extend from above the flat portion 11 to a side of the binding portion 12 away from the flat portion 11, the protective layer 730 can be arranged on the same layer as the polarizer 81, and the protective layer 130 can include a photocurable resin.

[0088] The shape of the packaging structure 30 matches the shape of the functional film layer 80, and can be attached to the side of the functional film layer 80 away from the display panel 10 through the adhesive layer 90; the packaging structure 30 includes but is not limited to a flexible substrate (not shown in the figure) and a flexible cover plate 31 that are sequentially away from the display panel 10, and the flexible substrate is located between the functional film layer 80 and the flexible cover plate 31, wherein the material of the flexible substrate includes but is not limited to one of cover glass (Coverwindow, CW) and ultra-thin glass (Ultra-Thin Glass, UTG), and the flexible cover plate 31 includes but is not limited to a combination of a cover material protective film (protect window, PW) and an optically clear adhesive (Optically Clear Adhesive, OCA); further, the material of the cover material protective film includes but is not limited to one of polyethylene glycol terephthalate (PET) and transparent polyimide (Colorless Polyimide, CPI).
