[0083] To make the objectives, technical solutions, and advantages of this disclosure clearer, embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Note that the implementation methods can be carried out in many different forms. Those skilled in the art will readily understand that the methods and content can be varied in various forms without departing from the spirit and scope of this disclosure. Therefore, this disclosure should not be construed as limited to the content described in the following embodiments. Without conflict, the embodiments and features in the embodiments of this disclosure can be arbitrarily combined with each other.

[0084] The ordinal numbers “first,” “second,” and “third” used in this specification are used to avoid confusion among the constituent elements, not to limit their quantity.

[0085] In this specification, for convenience, terms such as "middle," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer" are used to indicate orientation or positional relationships in conjunction with the accompanying drawings. This is solely for the purpose of facilitating the description and simplification, and does not imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this disclosure. The positional relationships of the constituent elements may be appropriately varied depending on the orientation of each constituent element being described. Therefore, the use of terms not limited to those described in the specification may be appropriately replaced as needed.

[0086] In this specification, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection, an indirect connection via an intermediate component, or a connection within two components. Those skilled in the art will understand the specific meaning of these terms in this disclosure based on the specific circumstances.

[0087] In this specification, "electrical connection" includes the situation where components are connected together by elements that have a certain electrical function. There are no particular limitations on what constitutes an "electrical function," as long as it allows for the transmission and reception of electrical signals between the connected components. Examples of "electrical functions" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements with various functions.

[0088] In this specification, "parallel" refers to two straight lines forming an angle of -10° or more and less than 10°, and therefore also includes angles of -5° or more and less than 5°. Similarly, "perpendicular" refers to two straight lines forming an angle of 80° or more and less than 100°, and therefore also includes angles of 85° or more and less than 95°.

[0089] In this specification, triangles, rectangles, trapezoids, pentagons, or hexagons are not strictly defined; they can be approximate triangles, rectangles, trapezoids, pentagons, or hexagons. Small deformations due to tolerances are possible, as are chamfers, curved edges, and other variations.

[0090] In the embodiments of this disclosure, "about" means a value that is not strictly limited and is within the range of process and measurement errors.

[0091] Furthermore, in describing representative embodiments, the specification may have presented methods and / or processes as a specific sequence of steps. However, the method or process should not be limited to the specific order of steps described herein, to the extent that it does not depend on such a specific order. As will be understood by those skilled in the art, other sequences of steps are also possible. Therefore, the specific order of steps set forth in the specification should not be construed as a limitation of the claims. Moreover, the claims concerning the method and / or process should not be limited to the steps performed in the written order, and those skilled in the art will readily understand that these orders can be varied and still remain within the spirit and scope of the embodiments of this application.

[0092] To protect the display panel, protective brackets are attached to the back of the display modules. Currently, these brackets are made of two materials: plastic and polyethylene terephthalate (PET). While plastic brackets offer high structural strength, their weight makes them prone to mold marks at the point where the display module adheres to the bracket. Furthermore, removing the bracket can damage the display panel. Additionally, plastic brackets are expensive to manufacture and require longer molding times. Therefore, PET brackets are currently the most commonly used material. However, the applicant has found that current PET brackets offer poor protection and are difficult to design to avoid obstacles, especially when there are multiple devices such as QR code modules on the side requiring large-area avoidance; in such cases, existing PET bracket designs are not feasible.

[0093] Figure 1 This is a schematic diagram of a display module according to an exemplary embodiment of the present disclosure. Figure 2 for Figure 1 Schematic diagram of section AA in the diagram. Figure 4 for Figure 1 A schematic diagram of the BB cross-section in the figure, the display module of the embodiment of this disclosure, such as Figure 1 , Figure 2 and Figure 4As shown, the display module includes a display panel 3 and a support structure 8. The display panel 3 may include a display section 9, a bending section 10, and a bonding section 11 connected in sequence. The support structure 8 may include a protective film 12 and a connecting component 13. For the display panel 3, the bending section 10 may be configured to fold towards the backlight side 19 of the display section 9. One end of the bonding section 11 in a first direction may be connected to the bending section 10. The bonding section 11 may have a circuit bonding area C1 on the side away from the display section 9, and the circuit bonding area C1 may have a first control device 7. For the support structure 8, the support structure 8 may be configured to avoid the first control device 7. The protective film 12 may be located on the side of the bonding section 11 away from the display section 9, and the protective film 12 may cover the bonding section 11. The connecting component 13 may be disposed on the surface of the protective film 12 facing the display panel 3. The connecting component 13 may include a first connector 16 and / or a second connector 15. The first connector 16 is located on the side of the first control device 7 near the bend 10 in the first direction, and the second connector 15 is located on at least one side of the first control device 7 in the second direction. Both the first and second directions are parallel to the display part 9 and are angled together. Thus, the display module of this example, by arranging the protective film 12 and the connecting component 13, effectively protects the bonding part 11 and avoids the device (first control device 7) on the ground side. The bracket structure 8 also has the advantages of easy application, low cost, and wide range of applications.

[0094] Figure 3 for Figure 1 The schematic diagram of the display panel in the figure, in some exemplary embodiments, such as Figure 2 and Figure 3As shown, the display module also includes a cover plate 1 and a composite layer 5 on the display panel 3. The display panel 3 may include a display part 9, a bending part 10, and a bonding part 11 connected in sequence. The display part 9, the bending part 10, and the bonding part 11 may be an integral piece. The display part 9 may have a light-emitting side 18 and a backlight side 19. When the display part 9 is lit, the light-emitting side 18 emits light to display text or images. One end of the display part 9 in a first direction may be connected to the bending part 10. The bending part 10 is folded to the backlight side 19 of the display part 9. The bonding part 11 is located on the backlight side 19 of the display part 9. The side of the display module with the bending part 10 in the first direction may be called the ground side, and the opposite side may be called the top side. The bending portion 10 can be made of a flexible material and can be bent. The bending portion 10 has metal traces, etc. During the production of the bending portion 10, it can be laid flat on the production equipment. During installation, the bending portion 10 can be folded to the backlight side 19 of the display portion 9, so that the bending portion 10 is in a bent state and remains in a bent state. The bonding portion 11 is parallel to the display portion 9. The bonding portion 11 has a circuit bonding area C1 and an empty area C2. The circuit bonding area C1 can be divided into a chip on panel (COP) area and a driver integrated circuit (D-IC) area. The first control device 7 is bonded to the bonding portion 11 corresponding to the driver integrated circuit area or the chip on panel area to form an electrical connection. The first control device 7 can be a QR code module, a connector module, etc. The empty area C2 is located on the side of the circuit bonding area C1 closer to the bending portion 10. No device is placed in the empty area C2. The composite layer 5 can be a multi-layered structure, such as a filling layer of silicone gel and a heat dissipation film of copper foil.

[0095] In some exemplary embodiments, such as Figure 2As shown, the display module may also include a bottom film (BF) 4, a bending spacer 6, and a light-transmitting layer 2. The bottom film 4 can be disposed on the display panel 3, located on the backlight side 19 surface of the display section 9 and on the bonding section 11. When the bending section 10 is in a bent state, the bottom film 4 covers the surface of the bonding section 11 facing the display section 9. The bottom film 4 can be prepared onto the display panel 3 during production. At this time, the bending section 10 is laid flat on the production equipment, and the bottom film 4 is positioned in one go. Additionally, the display module may also include a metal coating layer (MCL), which covers at least one side of the bending section 10 and protects the components it covers. The spacer 6 can be sandwiched between the second bottom film layer 16 and the composite layer 5. The spacer 6 can be double-sided acrylic adhesive made of PET (Polyethylene terephthalate) substrate. The spacer 6 is insulating and has a relatively high actual impedance. The light-transmitting layer 2 may include a curable optical adhesive (not shown in the figure), a polarizer (not shown in the figure), and an encapsulation layer (not shown in the figure). The encapsulation layer, polarizer, curable optical adhesive, and cover plate 1 are stacked sequentially in the direction away from the display unit 9. The encapsulation layer, polarizer, curable optical adhesive, and cover plate 1 can all transmit the light emitted from the display unit 9. The encapsulation layer and cover plate can protect the display unit 9. The polarizer 3 can reduce the impact of external light emission on the image display of the display unit 9.

[0096] In some exemplary embodiments, such as Figure 2 As shown, the protective film 12 can be made of polyethylene terephthalate (PET). PET protective film 12 is lightweight and soft, and will not damage other components of the display module after installation. It will also not cause damage to other components of the display module when pasting or removing the protective film 12. The unit cost of PET protective film 12 is relatively low. Compared to plastic supports, the protective film 12 in this example is manufactured using a die-cutting process, where the protective film 12 is cut from a single PET film using a cutter. The cost of the cutting mold is also low, and the mold opening time is very short.

[0097] Figure 5 for Figure 1 A schematic diagram of the support structure. Figure 6 for Figure 5 A schematic diagram of the support structure projected onto the first plane, as shown in some exemplary embodiments, such as... Figure 1 , Figure 5 and Figure 6As shown, the protective film 12 is a thin film structure with openings and uniform thickness. The thickness d1 of the protective film 12 can be from 0.2 mm to 0.5 mm. In this example, the thickness d1 of the protective film 12 can be 0.3 mm, but it is not limited to this. For example, the thickness d1 of the protective film 12 can be 0.4 mm, 0.2 mm, or 0.5 mm. The protective film 12 can be a rectangular film, but it is not limited to this. For example, the outer contour of the protective film 12 can be trapezoidal, parallelogram, or other regular / irregular shapes. A first through hole 17 can be opened on the protective film 12. The first through hole 17 is a rectangular hole and is centrally arranged on the protective film 12, so that the protective film 12 forms a rectangular ring shape, but it is not limited to this. For example, the first through hole 17 can be a trapezoidal hole, a parallelogram hole, a fan-shaped hole, or other regular / irregular shapes. For example... Figure 1 , Figure 2 and Figure 4 As shown, the protective film 12 is parallel to the display portion 9 and close to the bonding portion 11 in the first direction. The protective film 12 is arranged in the second direction, and in the second direction, both ends of the protective film 12 protrude from the display panel 3 at both ends, so that the protective film 12 spans the display panel 3. One end of the protective film 12 in the first direction extends beyond the edge of the display panel 3 with the bend portion 10, and the other end extends across the bonding portion 11 and the first control device 7. In addition, the first through hole 17 corresponds to the first control device 7, so that the taller first control device 7 can extend into the first through hole 17, forming a protective film 12 that avoids the first control device 7. The orthographic projection of the first control device 7 on the first plane can be located within the orthographic projection range of the first through hole 12 on the first plane. The orthographic projection of the first control device 7 on the first plane and the orthographic projection of the first through hole 12 on the first plane form a matching rectangle, and the orthographic projection of the first control device 7 on the first plane is slightly smaller than the orthographic projection of the first through hole 12 on the first plane. The first plane is a reference plane parallel to the display portion 9. Meanwhile, no devices are arranged in the empty area C2 of the bonding area 11. The empty area C2 and the protective film 12 are spaced apart. The empty area C2 is covered by the protective film 12, so that the protective film 12 can protect the empty area C2 of the bonding area 11.

[0098] In some exemplary embodiments, such as Figure 1 , Figure 5 and Figure 6As shown, the connecting assembly 13 includes a first connector 16, a second connector 15, and a third connector 14. All three connectors are bonded to the protective film 12 and are distributed around the outer periphery of the first through hole 17. The first connector 16 and the third connector 14 are located on opposite sides of the first through hole 17 in a first direction, and the second connectors are located on opposite sides of the first through hole 17 in a second direction. Therefore, the orthographic projections of the first connector 16, the second connector 15, and the third connector 14 onto the first plane 20 fall within the orthographic projection C3 of the protective film 12 onto the first plane. The orthographic projection of the first through hole 17 onto the first plane 20 lies between the orthographic projections of the first connector 16 and the third connector 14 onto the first plane 20. The orthographic projections of the first through hole 17 onto the first plane 20 also lie between the orthographic projections of the two second connectors 15 onto the first plane 20. In addition, the first connector 16 can be bonded to the display panel 3, while the second connector 15 and the third connector 14 can both be fitted with the display panel 3 with clearance.

[0099] Figure 7 for Figure 2 A partially enlarged schematic diagram at point F in the diagram, as shown in some exemplary embodiments, such as Figure 2 , Figure 5 and Figure 7As shown, the third connector 14 can be a rectangular strip arranged along the second direction. The third connector 14 is centered relative to the protective film 12 in the second direction, but is not limited to this. For example, the third connector 14 can be a curved strip, or its shape can be elliptical, trapezoidal, or other regular / irregular shapes. Alternatively, the third connector 14 may not be centered on the protective film 12. The third connector 14 includes a first adhesive layer 21, a first foam 22, and a second adhesive layer 23 sequentially stacked in a direction away from the protective film 12. The first foam 22 is made of foam material and has good cushioning properties. The first adhesive layer 21 and the second adhesive layer 23 can be double-sided adhesive. The thickness d3 of the first foam 22 can be from 0.2mm to 0.5mm. In this example, the thickness d3 of the first foam 22 can be 0.5mm, but is not limited to this. For example, the thickness d3 of the first foam 22 can be 0.3mm, 0.4mm, or 0.2mm. The thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can be the same, both ranging from 0.05 mm to 0.1 mm. In this example, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can both be 0.06 mm, but this is not a limitation. For example, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can both be 0.05 mm, 0.08 mm, or 0.09 mm. Alternatively, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can be different, but both are within the range of 0.05 mm to 0.1 mm. In some exemplary embodiments, such as... Figure 1 and Figure 6 As shown, the total projected area of ​​the third connector 14 on the first plane 20 is set to S mm. 2 The diagonal length of the display unit 9 is set to L mm, where S = L. For example, for a 3-inch display panel, the diagonal of the display unit 9 is approximately 3 inches (approximately 70 mm). The corresponding total projected area of ​​the third connector 14 on the first plane 20 is set to 70 mm². 2 For example, in an 8-inch mobile phone, the diagonal of the display unit 9 is approximately 8 inches (about 200mm), so that the total projected area of ​​the corresponding third connector 14 on the first plane 20 is set to 200mm². 2 The 20-inch in-vehicle display device has a diagonal of approximately 20 inches (about 500mm) for the display unit 9, resulting in a total projected area of ​​the corresponding third connector 14 on the first plane 20 of 500mm². The orthographic projection of the third connector 14 on the first plane 20 is set as a first projection C4, which is a rectangle. The second direction is aligned with the length direction of the outer contour of the first projection C4, and the length of the first projection C4 in the second direction can be amm. The first direction is aligned with the width direction of the outer contour of the first projection C4, and the length of the first projection C4 in the first direction can be bmm.

[0104] Figure 9 for Figure 2 A partially enlarged schematic diagram at point E in the middle, as shown in some exemplary embodiments, such as... Figure 2 , Figure 5 and Figure 9 As shown, the first connector 16 can be a rectangular strip arranged along the second direction. The first connector 16 is centered relative to the protective film 12 in the second direction, but is not limited to this. For example, the first connector 16 can be a curved strip, or its shape can be elliptical, trapezoidal, or other regular / irregular shapes. Alternatively, the first connector 16 may not be centered on the protective film 12. The first connector 16 includes a third adhesive layer 24 and a second foam 25 sequentially stacked in a direction away from the protective film 12. The second foam 25 is made of foam material, providing good cushioning. The third adhesive layer 24 can be double-sided adhesive. The thickness d6 of the second foam 25 can be from 0.2mm to 0.5mm. In this example, the thickness d6 of the second foam 25 can be 0.2mm, but is not limited to this. For example, the thickness d6 of the second foam 25 can be 0.3mm, 0.4mm, or 0.5mm. The thickness d5 of the third adhesive layer 24 can be from 0.05 mm to 0.1 mm. In this example, the thickness d5 of the third adhesive layer 24 can always be 0.05 mm, but it is not limited to this. For example, the thickness d5 of the third adhesive layer 24 can always be 0.06 mm, 0.07 mm, or 0.08 mm. For example... Figure 6 As shown, the orthographic projection C6 of the first connector 16 on the first plane 20 is within the range of the orthographic projection C3 of the protective film 12 on the first plane 20.

[0105] In some exemplary embodiments, such as Figure 2 , Figure 7 and Figure 9As shown, the first connector 16 is located on the side of the first control device 7 away from the bend 10 in the first direction, and the third connector 14 is located on the side of the first control device 7 away from the first connector 16 in the first direction, such that the first control device 7 is positioned between the first connector 16 and the third connector 14 in the first direction. Simultaneously, the first connector 16 and the binding part 11 are clearance-fitted, wherein the second foam 25 is bonded to the protective film 12 via the third adhesive layer 24. The second foam 25 and the binding part 11 are spaced apart or rest against the empty area C2 of the binding part 11. In this example, the second foam 25 and the binding part 11 are spaced apart with a spacing d7 not greater than 0.3 mm. The third connector 14 is bonded to the protective film 12 and the composite layer 5 respectively, wherein the first foam 22 is bonded to the protective film 12 via the first adhesive layer 21 and to the side of the composite layer 5 away from the display part 9 via the second adhesive layer 23.

[0106] Figure 8 for Figure 4 A partially enlarged schematic diagram at point G in the middle, as shown in some exemplary embodiments, such as... Figure 2 , Figure 5 and Figure 8 As shown, there are two second connectors 15. Both second connectors 15 can be rectangular strips arranged along the first direction. The second connectors 15 are centered relative to the protective film 12 in the first direction, but are not limited to this. The number of second connectors 15 can be three or more. For example, the second connectors 15 can be curved strips. For example, the second connectors 15 can not extend along the first direction. For example, the shape of the second connectors 15 can be elliptical, trapezoidal, or other regular / irregular shapes. For example, the second connectors 15 are not centered on the protective film 12. The second connectors 15 include a third adhesive layer 24 and a second foam 25 stacked sequentially in the direction away from the protective film 12. The second foam 25 is made of foam material and has good cushioning properties. The third adhesive layer 24 can be double-sided adhesive. The thickness d6 of the second foam 25 can be from 0.2 mm to 0.5 mm. In this example, the thickness d6 of the second foam 25 can be 0.2 mm, but it is not limited to this. For example, the thickness d6 of the second foam 25 can be 0.3 mm, 0.4 mm, or 0.5 mm. The thickness d5 of the third adhesive layer 24 can be from 0.05 mm to 0.1 mm. In this example, the thickness d5 of the third adhesive layer 24 can always be 0.05 mm, but it is not limited to this. For example, the thickness d5 of the third adhesive layer 24 can always be 0.06 mm, 0.07 mm, or 0.08 mm. For example... Figure 6As shown, the orthographic projection C5 of the two second connectors 15 on the first plane 20 is within the range of the orthographic projection C3 of the protective film 12 on the first plane 20. The two second connectors 15 are located on both sides of the first control device 7 in the second direction and are spaced apart from the first control device 7, such that the first control device 7 is located between the two second connectors 15 in the second direction. At the same time, the two second connectors 15 and the composite layer 5 are in clearance fit, wherein the second foam 25 is bonded to the protective film 12 through the third adhesive layer 24, and the second foam 25 and the composite layer 5 are spaced apart or abut against the composite layer 5. In this example, the second foam 25 and the composite layer 5 are spaced apart and the distance d7 is not greater than 0.3mm.

[0107] In some exemplary embodiments, such as Figure 2 and Figure 4 As shown, the third connector 14 is bonded to the composite layer 5, which serves as a connection for the protective film 12. The second connector 15 and the first connector 16 both serve as auxiliary supports, so that the protective film 12 parallel to the display part 9 is effectively supported, the bracket structure is not easily deformed, and the disadvantage of the relatively soft PET material protective film 12 is compensated for. This improves the overall strength of the bracket structure and allows it to avoid the first control device 7.

[0108] Figure 10 for Figure 2 A schematic diagram of the protective film fabrication process is provided. In some exemplary embodiments, such as... Figure 10 As shown, during the die-cutting process of the protective film 12, a first through hole 17 needs to be die-cut. At the same time, a second bracket 26 can be cut out at the position where the first through hole 17 is die-cut. The second bracket 26 can be used on other equipment. This reduces waste in the die-cutting process, improves material utilization, reduces production costs, and increases production efficiency.

[0109] Figure 11 This is a schematic diagram of a support structure for this exemplary embodiment. In some exemplary embodiments, such as... Figure 11 As shown, the number of third connectors 14 can be two, and the two third connectors 14 are arranged at intervals in the second direction, but it is not limited to this. For example, the number of third connectors 14 can be three or more, and the three or more third connectors 14 are also arranged at intervals in the second direction; or the number of third connectors 14 can be two, and the two third connectors 14 are arranged at intervals in the first direction; or the number of third connectors 14 can be three or more, and the three or more third connectors 14 are arranged at intervals in the first and second directions.

[0110] Figure 12 This is a schematic diagram of another support structure for this exemplary embodiment. In some exemplary embodiments, such as Figure 12As shown, the number of first connectors 16 can be two, and the two first connectors 16 are arranged at intervals in the second direction, but it is not limited to this. For example, the number of first connectors 16 can be three or more, and the three or more first connectors 16 are also arranged at intervals in the second direction; for another example, the number of first connectors 16 can be two, and the two first connectors 16 are arranged at intervals in the first direction; for yet another example, the number of first connectors 16 can be three or more, and the three or more first connectors 16 are arranged at intervals in the first direction and the second direction.

[0111] Figure 13 This is a schematic diagram of another support structure in this exemplary embodiment. In some exemplary embodiments, such as Figure 13 As shown, the number of second connectors 15 can be four. The first through hole 17 has two second connectors 15 on both sides of the second direction. The two second connectors 15 are arranged at intervals in the first direction, but it is not limited to this. For example, the number of second connectors 15 can be six or more. The first through hole 17 has three or more second connectors 15 on both sides of the second direction. The three or more second connectors 15 are also arranged at intervals in the second direction. For another example, the number of second connectors 15 on both sides of the first through hole 17 in the second direction can be different. For another example, the first through hole 17 has multiple second connectors 15 on at least one side of the second direction. The multiple second connectors 15 are arranged at intervals in the second direction or are arranged at intervals inclined to the first direction and the second direction.

[0112] Figure 14 This is a schematic diagram of a protective film according to an exemplary embodiment. Figure 15 This is a schematic diagram of another support structure for this exemplary embodiment. In some exemplary embodiments, such as Figure 14 and Figure 15As shown, the protective film 12 includes two separate first protective members 27, which are joined together to form the protective film 12. The two first protective members 27 are symmetrical, both U-shaped, and each has a first groove 28. When joined, the two first protective members 27 are coplanar and their first grooves 28 are opposite, forming a rectangular ring. The two first grooves 28 constitute a first through hole 17. Simultaneously, each first protective member 27 is provided with a first connector 16, a second connector 15, and a third connector 14, and these connectors on the two first protective members 27 are also symmetrical. However, this is not limited to the above. For example, the protective film 12 may include at least two or more separate first protective members 27. For example, the separate first protective members 27 may no longer be symmetrical. For example, the first connector 16, the second connector 15, and the third connector 14 on the first protective member 27 may no longer be symmetrical. For example, some first protective members 27 may have the first connector 16, the second connector 15, and the third connector 14, while other first protective members 27 may not have one or two of the first connector 16, the second connector 15, and the third connector 14.

[0113] Figure 16 This is a schematic diagram of another display module according to this exemplary embodiment. Figure 17 for Figure 16 A schematic diagram of the HH-direction cross-section, in some exemplary embodiments, such as Figure 16 and Figure 17 As shown, both the first control device 7 and the bonding part 11 are covered by the protective film 12, which can protect both the first control device 7 and the bonding part 11 simultaneously. The protective film 12 is located on the side of the first control device 7 away from the bonding part 11 and is spaced apart from the first control device 7, thus avoiding contact with the first control device 7. The orthographic projections of the first control device 7 and the bonding part 11 on the first plane are both located within the orthographic projection of the protective film 12 on the first plane. Both the cover plate 1 and the protective film 12 are parallel to the first plane. The connecting assembly only has two second connectors 15, located on opposite sides of the first control device 7 in the second direction. The orthographic projections of the second connectors 15 on the first plane do not overlap with the orthographic projections of the display panel 3 on the first plane. The second connectors 15 are respectively bonded to the cover plate 1 and the protective film 12.

[0114] like Figure 19 for Figure 16 A schematic diagram of the connection between the protective bracket and the cover plate. Figure 20 for Figure 19 A partially enlarged schematic diagram at point O in the diagram, as shown in some exemplary embodiments, such as Figure 19 and Figure 20As shown, the cover plate 1 has protruding extensions 29 on both edges in the second direction. The extensions 29 are rectangular and located at the end of the cover plate 1 in the first direction near the binding part 11, making the cover plate 1 convex in shape.

[0115] Figure 18 for Figure 17 A partially enlarged schematic diagram at point J in the diagram, as shown in some exemplary embodiments, such as Figure 17 and Figure 18 As shown, there are two second connectors 15. Both second connectors 15 can be rectangular strips arranged along the first direction, but are not limited thereto. The number of second connectors 15 can be three or more. For example, the second connectors 15 can be curved strips, or they can not extend along the first direction. For example, the shape of the second connectors 15 can be elliptical, trapezoidal, or other regular / irregular shapes. The second connector 15 includes a first adhesive layer 21, a first foam 22, and a second adhesive layer 23 stacked sequentially in the direction away from the protective film 12. The first foam 22 is made of foam material and has good cushioning properties. The first adhesive layer 21 and the second adhesive layer 23 can be double-sided adhesive. The thickness d3 of the first foam 22 can be from 0.2 mm to 0.8 mm. In this example, the thickness d3 of the first foam 22 can be 0.5 mm, but is not limited thereto. For example, the thickness d3 of the first foam 22 can be 0.3 mm, 0.4 mm, or 0.2 mm. The thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can be the same, both ranging from 0.05mm to 0.1mm. In this example, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can both be 0.06mm, but this is not a limitation. For example, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can both be 0.05mm, 0.08mm, or 0.09mm. Alternatively, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can be different, but both should be within the range of 0.05mm to 0.1mm. The dimension of the second connector 15 in the second direction is set to be no less than 4mm. If it is too narrow, the second connector 15 is prone to deformation and loses its fitting and supporting effect.

[0116] In some exemplary embodiments, such as Figure 16 , Figure 19 and Figure 20As shown, the extension 29 is provided in a one-to-one correspondence with the second connector 15 in the direction perpendicular to the display part 9. The orthographic projections of the protective film 12 and the second connector 15 on the first plane are both located within the orthographic projection of the cover plate 1 on the first plane. The orthographic projection of the second connector 15 on the first plane is set to be located within the orthographic projection of the extension 29 on the first plane, and the orthographic projection of the second connector 15 on the first plane is set to be located within the orthographic projection of the protective film 12 in the first direction. One end of the protective film 12 in the first direction is close to the edge of the cover plate 1, and the other end extends upward.

[0117] In some exemplary embodiments, such as Figure 17 and Figure 18 As shown, the second connector 15 can be bonded to the protective film 12 and the extension 29 respectively. The first foam 22 is bonded to the protective film 12 through the first adhesive layer 21 and to the side of the cover plate 1 facing the display part 9 through the second adhesive layer 23. The two second connectors 15 support the first space 31 between the protective film 12 and the cover plate 1, so that the protective film 12, the second connectors 14 and the cover plate 1 form a wrap-around structure relative to the display panel 3 and the first control device 7, which has a good protective effect and can avoid the devices on the module side. At the same time, the side attachment or tearing off of the bracket structure can avoid the adverse risks such as bumps and scratches caused to the display module by the process operation. For example, Figure 20 As shown, the distance between the orthographic projection of the second connector 15 on the protective film 12 and one edge of the protective film 12 in the first direction is d10, the distance between the orthographic projection of the second connector 15 on the protective film 12 and another edge of the protective film 12 in the first direction is d12, and the distance between the orthographic projection of the second connector 15 on the protective film 12 and one edge of the protective film 12 in the second direction is d11. The values ​​of d10, d11, and d12 are all set to be no greater than 2mm, so that the minimum distance between the orthographic projection of the second connector 15 on the protective film 12 and the edge of the protective film 12 is no greater than 2mm. In this example, d10 = d12 = 1mm and d11 = 0.5mm, but it is not limited to this. For example, the values ​​of d10, d11, and d12 are the same and all are zero, or the values ​​of d10, d11, and d12 are the same and none are greater than 2mm.

[0118] In some exemplary embodiments, such as Figure 16 As shown, the display module also includes a second control device 30, which is located on the side of the first control device 7 away from the bonding portion 11 in a first direction. The orthographic projection of the protective film 12 on the first plane is configured not to overlap with the orthographic projection of the second control device 30 on the first plane. The first plane is parallel to the cover plate 1 and the protective film 12. In the first direction, the distance d8 between the protective film 12 and the second control device 30 is set to be greater than or equal to 1 mm, so that the protective film 12 avoids the second control device 30, which has a higher height. In some exemplary embodiments, such as... Figure 16 As shown, the binding part 11 includes a first end portion 39, which is connected to the bending part. The orthographic projection of the first end portion 39 on the first plane is set to be located within the orthographic projection of the protective film 12 on the first plane. Moreover, the distance between the first end portion 39 and the protective film 12 in the first direction can be set to be greater than or equal to 3 mm to protect the binding part 11 from finger injuries of the operator. In this example, the value of the distance d9 between the first end portion 39 and the protective film 12 in the first direction is 3 mm, but it is not limited to this. For example, the value of d9 can be 5 mm, 4 mm or 6 mm.

[0119] Figure 21 This is a schematic diagram of another display module according to this exemplary embodiment. Figure 22 for Figure 21 A schematic diagram of the QQ-directed cross-section, in some exemplary embodiments, such as Figure 21 and Figure 22 As shown, the first control device 7 and the bonding portion 11 are at least partially covered by the protective film 12, which can simultaneously protect the first control device 7 and the bonding portion 11. The protective film 12 is located on the side of the first control device 7 away from the bonding portion 11 and is spaced apart from the first control device 7, thus avoiding contact with the first control device 7. The orthographic projections of the first control device 7 and the bonding portion 11 on the first plane are at least partially located within the orthographic projections of the protective film 12 on the first plane. Both the cover plate 1 and the protective film 12 are parallel to the first plane. The connecting assembly has only one first connector 16, which is located on one side of the first control device 7 in the first direction. The orthographic projection of the first connector 16 on the first plane does not overlap with the orthographic projection of the display panel 3 on the first plane. The first connector 16 is configured to be bonded to both the cover plate 1 and the protective film 12.

[0120] Figure 23 for Figure 22 A partially enlarged schematic diagram at point P in the diagram, as shown in some exemplary embodiments, such as Figure 22 and Figure 23As shown, there is one first connector 16. Each first connector 16 can be a rectangular strip arranged along the second direction. The first connector 16 is centered relative to the protective film in the second direction, but is not limited to this. The number of first connectors 16 can be two or more. For example, the first connector 16 can be a curved strip, or it can not extend along the second direction, or its shape can be elliptical, trapezoidal, or other regular / irregular shapes. The first connector 16 includes a first adhesive layer 21, a first foam 22, and a second adhesive layer 23 sequentially stacked in the direction away from the protective film 12. The first foam 22 is made of foam material and has good cushioning properties. The first adhesive layer 21 and the second adhesive layer 23 can be double-sided adhesive. The thickness d3 of the first foam 22 can be from 0.2 mm to 0.8 mm. In this example, the thickness d3 of the first foam 22 can be 0.5 mm, but it is not limited to this. For example, the thickness d3 of the first foam 22 can be 0.3 mm, 0.4 mm, or 0.2 mm. The thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can be the same, and both can be from 0.05 mm to 0.1 mm. In this example, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can both be 0.06 mm, but it is not limited to this. For example, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can both be 0.05 mm, 0.08 mm, or 0.09 mm. Alternatively, the thickness d2 of the first adhesive layer 21 and the thickness d4 of the second adhesive layer 23 can be different, but both are within the range of 0.05 mm to 0.1 mm.

[0121] In some exemplary embodiments, such as Figure 21 , Figure 22 and Figure 23As shown, the orthographic projections of the protective film 12 and the first connector 16 on the first plane are both located within the orthographic projection of the cover plate 1 on the first plane. The orthographic projection of the first connector 16 on the first plane is set to be located within the orthographic projection of the protective film 12 in the first direction. One end of the protective film 12 in the first direction is close to the edge of the cover plate 1, and the other end extends upward. The first connector 16 can be bonded to the protective film 12 and the cover plate 1 respectively. The first foam 22 is bonded to the protective film 12 through the first adhesive layer 21 and to the side of the cover plate 1 facing the display part 9 through the second adhesive layer 23. The first connector 16 supports the first space 31 between the protective film 12 and the cover plate 1, forming a ground-side bonding of the bracket structure, which can effectively reduce the width of the protective film 12 (i.e., the dimension in the first direction) and reduce the cost of the bracket structure. At the same time, the first connector 16 is close to the bonding area 11, which provides better protection for the bonding area 11. The first control device 7 includes a first plate segment 33 connected to the binding part 11. The protective film 12 extends to the side of the first plate segment 33 away from the binding part 11 and is spaced apart from the first plate segment 33 so that the protective film 12 avoids the first control device 7. Under the cover of the protective film 12, the other structures of the first control device 7, except for the part of the first plate segment 33, are not covered by the protective film 12. Figure 24 for Figure 21 The diagram shows the connection between the third connector and the cover plate. In some exemplary embodiments, such as... Figure 24 As shown, the first connector 16 is arranged along the second direction, the length of the binding part 11 in the second direction is set to L1, and the length of the first connector 16 in the second direction is set to L2, wherein 0.8×L1≤L2≤1.2×L1. In this example, L2=0.95×L1, but it is not limited to this. For example, L2=L1, or L2=0.8×L1, or L2=1.1×L1.

[0122] Figure 25 This is a schematic diagram of a first connector in an exemplary embodiment of the present invention. Figure 26 for Figure 25 The enlarged schematic diagram at point W shows that in some exemplary embodiments, the first connector 16 includes three separate adhesive strips 38, each extending along a second direction and spaced apart. The gap between two adjacent adhesive strips 38 in the second direction is set to be no greater than 30 mm to prevent deformation of the protective film at the gap. The size of the gap between two adjacent adhesive strips 38 is d13, and the size of the other gap is d14, where d13 = d14, and neither d13 nor d14 is greater than 30 mm. In this example, d13 = d14 = 20 mm, but it is not limited to this; for example, d13 = d14 = 10 mm, d13 = d14 = 30 mm, d13 = d14 = 15 mm, or d13 is not equal to d14, but neither is greater than 30 mm.

[0123] In some exemplary embodiments, such as Figure 25 and Figure 26 As shown, the three adhesive strips 38 include a first adhesive strip 35, a second adhesive strip 36, and a third adhesive strip 37 arranged sequentially along the second direction. All three strips are arranged along the second direction. The cover plate 1 has protruding extensions 34 at the edges of the corresponding adhesive strips 38, and the first, second, and third adhesive strips 35 and 36 are all bonded to these extensions 34. The dimensions of the first and third adhesive strips 35 and 37 in the first direction are the same, while the dimension of the second adhesive strip 36 in the first direction is larger than the former two. The end of the second adhesive strip 36 facing the first control device 7 protrudes in a first direction from the end faces of the first adhesive strip 35 and the third adhesive strip 37 facing the first control device 7. The first adhesive strip 35, the second adhesive strip 36, and the third adhesive strip 37 are flush with each other on the end faces away from the first control device 7, and the first adhesive strip 35 and the third adhesive strip 37 are flush with each other on the end faces facing the first control device 7, so that the first adhesive strip 35, the second adhesive strip 36, and the third adhesive strip 37 form an approximately "convex" shape. In this way, the three adhesive strips 38 can prevent the protective film from collapsing in the middle due to a concave shape, which is beneficial to improving the impact and pressure resistance of the support structure. The distance D between the end face of the second adhesive strip 36 facing the first control device 7 and the end face of the first adhesive strip 35 facing the first control device 7 is set, where 0.3mm ≤ D ≤ 0.5mm. In this example, D = 0.4mm, but it is not limited to this. For example, D = 0.3mm, D = 0.5mm, or D = 0.35mm. The distance d15 between the end face of the second adhesive strip 36 facing the first control device 7 and the end face of the third adhesive strip 35 facing the first control device 7 is set, where 0.3mm ≤ d15 ≤ 0.5mm. In this example, d15 = D = 0.4mm, but it is not limited to this. For example, d15 = 0.3mm, d15 = 0.5mm, or d15 = 0.35mm.

[0124] In some exemplary embodiments, such as Figure 23 As shown, the second adhesive layer 23 can be made of strong or weak adhesive or a weak adhesive film to facilitate the separation of the support structure and the cover plate.

[0125] In some exemplary embodiments, a display device is provided, which includes the display module described above, and the display device may be an OLED display device. The display device provided in the embodiments of this disclosure can be applied to electronic devices, such as mobile phones, tablets, televisions, monitors, laptops, digital photo frames, navigators, in-vehicle displays, and any product or component with display function, such as wearable devices, smartwatches, smart bracelets, smart glasses, smart headphones, smart clothing, head-mounted displays, etc.

[0126] In conjunction with the above embodiments, the display module of this example, by arranging the protective film 12 and connecting components 13, effectively protects the bonding part 11 and avoids ground-side devices (first control device 7). The bracket structure 8 also has the advantages of easy application, low cost, and wide application range. The bracket structure with a rectangular ring-shaped protective film is bonded by the third connector 14. The first and second connectors provide auxiliary support, which can avoid ground-side devices and effectively protect the bonding area. During the die-cutting process, the rectangular ring-shaped protective film 12 needs to be die-cut to form a first through hole 17. At the position where the first through hole 17 is die-cut, a second bracket 26 can be cut simultaneously. The second bracket 26 can be used on other equipment, thereby reducing waste during the die-cutting process, improving material utilization, reducing production costs, and improving production efficiency and die-cutting layout utilization. The rectangular ring-shaped protective film 12 can be a split structure, which can be convenient for factory bonding. The connecting assembly may only have a second connector 15, which can be bonded to the protective film 12 and the extension 29 respectively. The two second connectors 15 support the first space 31 between the protective film 12 and the cover plate 1, so that the protective film 12, the second connector 14 and the cover plate 1 form a wrap-around structure relative to the display panel 3 and the first control device 7, which provides good protection and avoids the devices on the ground side of the module. At the same time, the side bonding or peeling off of the bracket structure can avoid the adverse risks such as bumps and scratches caused to the display module by the process operation. The connecting assembly may only have a first connector 16, which forms the ground side bonding of the bracket structure, which can effectively reduce the width of the bracket structure (i.e., the dimension in the first direction) and reduce the cost of the bracket structure. At the same time, the first connector 16 is close to the bonding area 11, which provides better protection for the bonding area 11.
