[0006] In some embodiments, the bonding portion is provided with a first adhesive layer, a bonding buffer layer, a second adhesive layer and a release protective film on the side adjacent to the display panel in sequence.

[0007] In some embodiments, the adhesive strength of the first adhesive layer is 1000 gf / inch to 1200 gf / inch, and the adhesive strength of the second adhesive layer is 100 gf / inch to 600 gf / inch.

[0008] In some embodiments, the auxiliary support surface is provided with an auxiliary buffer layer for cushioning.

[0009] In some embodiments, the auxiliary support extends toward the tearing direction and is an arc-shaped surface, an involute surface, or a plane that gradually moves away from the back of the display panel.

[0010] In some embodiments, the positioning support is provided with a support buffer layer for cushioning.

[0011] In some embodiments, the bonding buffer layer, the auxiliary buffer layer, and the supporting buffer layer are foam layers.

[0012] In some embodiments, the display panel protective bracket further includes a side shielding portion disposed on the shielding portion and extending toward the display panel, the side shielding portion shielding the bonding area located at the end of the display panel.

[0013] In some embodiments, the support portion is located on the side opposite to the tearing direction of the tearing aid portion.

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application.

In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0036] This application is described below with reference to the accompanying drawings and specific embodiments:

[0037] This application provides a display panel protective bracket, such as Figures 5 to 11As shown, the display panel protective bracket includes a shielding part 100, a connecting part 200, a fitting part 300, a supporting part 400, and a tear-off auxiliary part 500. The shielding portion 100, when projected onto the back of the display panel 1000, at least covers the bonding area 1100 and the integrated circuit chip 1200 on the back of the display panel 1000. The connecting portion 200 is disposed on the shielding portion 100. The bonding portion 300 is connected to the shielding portion 100 via the connecting portion 200 and is used to bond with the display panel 1000. The supporting portion 400 is disposed on the shielding portion 100 and has a positioning support surface 410 that abuts against the back of the display panel 1000. The tear-off auxiliary portion 500 is disposed at any one or more of the connecting portion 200, the bonding portion 300, and the shielding portion 100. The tear-off auxiliary portion 500 has an auxiliary support surface 510 that abuts against the back of the display panel 1000, and the extending direction of the auxiliary support surface 510 relative to the bonding portion 300 is the same as the tear-off direction of the display panel protective bracket.

[0038] The display panel protective bracket provided in this application is attached to the back of the display panel 1000 via the fitting part 300, thereby achieving the purpose of connecting the display panel protective bracket to the back of the display panel 1000. At the same time, it is supported on the back of the display panel 1000 by the support part 400, so that the shielding part 100 is suspended on the back of the display panel 1000 and covers the bonding area 1100 and integrated circuit chip 1200 on the back of the display panel 1000. Thus, the shielding part 100 can shield and protect the bonding area 1100 and integrated circuit chip 1200 on the display panel 1000, which are easily damaged. When the display panel protective bracket is peeled off from the back of the display panel 1000, the adhesive part 300 is gradually separated from the back of the display panel 1000 by the auxiliary support surface 510 of the peeling aid 500 in the peeling direction. During the peeling process, the auxiliary support surface 510 achieves "surface contact" between the display panel protective bracket and the back of the display panel 1000, which can reduce or eliminate the pressure of the display panel protective bracket on the back of the display panel 1000, so as to avoid the generation of mold marks.

[0039] It should be noted that, in the embodiments of this application, as... Figure 4 and Figure 8 As shown, the tearing direction is the direction from the part that leaves the display panel 1000 first to the part that leaves the display panel 1000 last during the separation process of the display panel protective bracket from the display panel 1000.

[0040] The display panel 1000 is a major component of electronic devices such as mobile phones, tablets, and watches. During the production of these electronic devices, the display panel 1000 often needs to be handled, packaged, and shipped. However, because the bonding area 1100 and integrated circuit chip 1200 of the display panel 1000 are relatively fragile and easily damaged, protective brackets are required for protection.

[0041] like Figures 1 to 4 As shown, traditional protective brackets 2000 are generally injection molded from polycarbonate (PC) material. These traditional protective brackets 2000 are characterized by their rigidity and heavy weight, providing good support and protection. For example... Figure 3 As shown, the bonding head 2100 of the conventional protective bracket 2000 is provided with a foam buffer layer 2220. The foam buffer layer 2220 is recessed by 0.3mm to 1.0mm relative to the bonding head 2100. For example, the foam buffer layer 2220 can be recessed by 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.0mm, etc., relative to the bonding head 2100. The foam buffer layer 2220, the first double-sided adhesive 2210, the second double-sided adhesive 2230, and the release film 2240 are flush in the tear-off direction. The foam buffer layer 2220 is attached to the bonding head 2100 by the first double-sided adhesive 2210. At the same time, a second double-sided adhesive 2230 is provided on the other side of the foam buffer layer 2220. The second double-sided adhesive 2230 is protected by the release film 2240. After removing the release film 2240, it can be attached to the back of the display panel 1000 by the second double-sided adhesive 2230. Because the traditional protective bracket 2000 has an inwardly recessed foam buffer layer 2220, the foam buffer layer 2220 can only provide protection in the direction perpendicular to the plane of the display panel 1000. It provides no protection in the direction parallel to the plane of the display panel 1000. When the traditional protective bracket 2000 is removed from the back of the display panel 1000, as... Figure 4 As shown in the diagram, the tearing direction is indicated by the arrow. Because the traditional protective bracket 2000's bonding head 2100 lacks the cushioning protection of the side foam buffer layer 2220, the side of the bonding head 2100 directly presses against the back of the display panel 1000, generating significant pressure locally on the back of the display panel 1000. Therefore, the traditional protective bracket 2000 is prone to leaving mold marks 3000 on the display panel 1000. Figure 4As shown, when the end customer peels off the traditional protective bracket 2000, the side of the bonding head 2100 of the traditional protective bracket 2000 makes rigid contact with the display panel 1000 in a direction parallel to the plane where the display panel 1000 is located, and presents a "line contact" manner. This generates a large pressure on the heat dissipation film (SCF) on the back of the display panel 1000, which can easily damage the heat dissipation film on the back of the display panel 1000. At the same time, an irreversible outward bulge occurs on the front of the display panel 1000, forming a mold mark 3000 on the front of the display panel 1000.

[0042] like Figure 4 As shown, the process of the traditional protective bracket 2000 being peeled off from the back of the display panel 1000 can be abstracted as the process of the traditional protective bracket 2000 separating from the side of the bonding head 2100. The contact between the side of the bonding head 2100 and the display panel 1000 is a "line contact", and the molded 3000 is caused by the side of the bonding head 2100 damaging the display panel 1000.

[0043] Based on the above findings, this application, by providing a tear-off assist 500, replaces the "line contact" between the side of the bonding head 2100 and the back of the display panel 1000 when the display panel protective bracket is torn off from the back of the display panel 1000 with a "surface contact" between the tear-off assist 500 and the back of the display panel 1000. In other words, the process of tearing the display panel protective bracket off the back of the display panel 1000 can be abstracted as the process of the display panel protective bracket separating around the auxiliary support surface 510 of the tear-off assist 500. The "surface contact" increases the contact area, thereby reducing the excessive pressure exerted on the back of the display panel 1000 during tear-off, thus preventing the formation of mold marks on the display panel 1000.

[0044] In the embodiments of this application, such as Figures 5 to 11 As shown, the shielding part 100 is used to shield the easily damaged bonding area 1100 and integrated circuit chip 1200 on the back of the display panel 1000, protecting the bonding area 1100 and integrated circuit chip 1200 from damage caused by collisions, etc. Optionally, the shielding part 100 can be flat, and its size can be adaptively adjusted according to the size and position of the bonding area 1100 and integrated circuit chip 1200 on the back of the display panel 1000; the area of ​​the shielding part 100 can also be appropriately increased to improve the adaptability of the display panel protective bracket, so that the display panel protective bracket can be used for display panels 1000 of different specifications.

[0045] In the embodiments of this application, such as Figures 5 to 11As shown, the connecting portion 200 connects between the shielding portion 100 and the bonding portion 300, allowing the bonding portion 300 to extend to a position where it can be bonded to the back of the display panel 1000; the supporting portion 400 connects to the shielding portion 100 and can be supported on the display panel 1000. That is, the shielding portion 100, supported by the connecting portion 200, the bonding portion 300, and the supporting portion 400, is suspended on the back of the display panel 1000 to shield the bonding area 1100 and the integrated circuit chip 1200 on the back of the display panel 1000. Simultaneously, by bonding the bonding portion 300 to the display panel 1000, the display panel protective bracket can be fixedly attached to the back of the display panel 1000, facilitating the handling and shipping of the display panel protective bracket and the display panel 1000 together.

[0046] In the embodiments of this application, it should be noted that, in order to avoid the bonding part 300 and the support part 400 damaging the bonding area 1100 and the integrated circuit chip 1200, the placement position of the bonding part 300 and the support part 400 needs to avoid the bonding area 1100 and the integrated circuit chip 1200 on the back of the display panel 1000.

[0047] In the embodiments of this application, such as Figures 5 to 11 As shown, the location of the tear-off auxiliary part 500 can be determined from the perspectives of spatial location conditions, the size of the display panel protective bracket, manufacturing cost, and ease of tearing. The tear-off auxiliary part 500 can be placed at any one or several of the connecting part 200, the fitting part 300, and the shielding part 100, and the size and location of the auxiliary support surface 510 can be adjusted adaptively.

[0048] In this embodiment, as Figures 5 to 10 As shown, by making the extension direction of the auxiliary support surface 510 relative to the bonding portion 300 the same as the tear-off direction of the display panel protective bracket, it can be ensured that when the display panel protective bracket is torn off, the display panel protective bracket flips around the auxiliary support surface 510 and is supported on the back of the display panel 1000 by the auxiliary support surface 510.

[0049] In the embodiments of this application, the display panel protective bracket can be integrally molded using an injection molding process, and the tear-off auxiliary part 500 and other parts of the display panel protective bracket can be made of the same material. Alternatively, the display panel protective bracket can be manufactured using a two-color injection molding process, so that the tear-off auxiliary part 500 and other parts of the display panel protective bracket can be made of different materials. This allows the tear-off auxiliary part 500 to be made of a relatively soft material, reducing its hardness and eliminating the need for an auxiliary buffer layer 520 on the tear-off auxiliary part 500.

[0050] In other embodiments, the auxiliary tear-off part can also be prepared separately and then connected to the main body of the display panel protective bracket by means of adhesion, snap-fit ​​or other connection methods.

[0051] As an alternative implementation method, such as Figures 5 to 10 As shown, the bonding portion 300 is provided with a first adhesive layer 310, a bonding buffer layer 320, a second adhesive layer 330 and a release protective film 340 on the side adjacent to the display panel 1000.

[0052] In the embodiments of this application, such as Figures 5 to 10 As shown, one side of the bonding buffer layer 320 is bonded to the side of the bonding portion 300 adjacent to the display panel 1000 via the first adhesive layer 310, while the other side of the bonding buffer layer 320 can be bonded to the display panel 1000 via the second adhesive layer 330. When the display panel protective bracket is supplied, a release protective film 340 can also be provided on the second adhesive layer 330 to protect the second adhesive layer 330.

[0053] In an embodiment of this application, optionally, the release liner 340 has a tear handle protruding relative to the second adhesive layer 330, which allows the release liner 340 to be easily removed from the second adhesive layer 330.

[0054] In the display panel protective bracket of this application, the second adhesive layer 330 can be a medium-weak adhesive, and the adhesive strength of the second adhesive layer 330 can be 100gf / inch to 600gf / inch. For example, the adhesive strength of the second adhesive layer 330 can be 100gf / inch, 200gf / inch, 300gf / inch, 400gf / inch, 500gf / inch, 600gf / inch, etc. By making the second adhesive layer 330 a medium-weak adhesive with relatively low adhesive strength, the display panel protective bracket can be attached to the back of the display panel 1000 through the second adhesive layer, and the relatively low adhesive strength also makes it easy for the terminal to peel the display panel protective bracket from the back of the display panel 1000. The first adhesive layer 310 can be a strong adhesive, and the adhesive strength of the first adhesive layer 310 can be 1000gf / inch to 1200gf / inch. For example, the adhesive strength of the first adhesive layer 310 can be 1000 gf / inch, 1100 gf / inch, 1200 gf / inch, etc. By making the first adhesive layer 310 a strong adhesive with relatively high adhesive strength, a firm bond between the bonding buffer layer 320 and the bonding portion 300 can be ensured. The bonding buffer layer 320 can be made of cushioning materials such as foam. The bonding buffer layer 320 provides a cushioning effect for the bonding portion 300, preventing the bonding portion 300 from damaging the display panel 1000.

[0055] In the display panel protective bracket of this application, the first adhesive layer 310 and the second adhesive layer 330 can be double-sided adhesives with different adhesion strengths.

[0056] As an alternative implementation method, such as Figure 5 and Figure 7 As shown, an auxiliary buffer layer 520 for buffering is provided on the auxiliary support surface 510.

[0057] In the embodiments of this application, such as Figure 5 and Figure 7 As shown, the auxiliary buffer layer 520 can be made of cushioning materials such as foam. The auxiliary buffer layer 520 can be attached to the side of the auxiliary support surface 510 adjacent to the display panel 1000 via the auxiliary adhesive layer 530. The auxiliary buffer layer 520 can provide a cushioning effect for the auxiliary support surface 510, preventing the auxiliary support surface 510 from damaging the display panel 1000. The auxiliary adhesive layer 530 can be made of a strong adhesive with an adhesion strength of 1000 gf / inch to 1200 gf / inch, for example, 1000 gf / inch, 1100 gf / inch, 1200 gf / inch, etc. This relatively strong adhesive ensures that the auxiliary buffer layer 520 is firmly bonded to the auxiliary support surface 510, preventing the auxiliary buffer layer 520 from detaching.

[0058] In the display panel protective bracket of this application, the structure of the auxiliary buffer layer 520 is adaptively adjusted according to the structure of the auxiliary support surface 510. For example... Figure 5 As shown, the auxiliary support surface 510 is an arc-shaped surface, and the auxiliary buffer layer 520 is attached to the auxiliary support surface 510 in an arc shape through the auxiliary adhesive layer 530. Figure 7 As shown, the auxiliary support surface 510 is a plane, and the auxiliary buffer layer 520 is attached to the auxiliary support surface 510 in a planar manner through the auxiliary adhesive layer 530.

[0059] As an alternative implementation method, such as Figures 5 to 8 As shown, the auxiliary support surface 510 extends in the tearing direction and gradually moves away from the curved surface, involute surface or plane on the back of the display panel 1000.

[0060] In this application, extending the auxiliary support surface 510 in the tearing direction (as indicated by the arrow in the figure) and gradually moving away from the curved surface, involute surface, or plane on the back of the display panel 1000 ensures that during the process of tearing the display panel protective bracket from the display panel 1000, the display panel protective bracket rotates around the auxiliary support surface 510 and gradually separates from the display panel 1000. This ensures that the force on the back of the display panel 1000 is small and dispersed to a larger contact surface during the separation process, thereby avoiding excessive local pressure on the back of the display panel 1000 that could lead to molding.

[0061] In the embodiments of this application, using Figure 5 and Figure 6 For example, the process of the display panel protective bracket being torn apart from the display panel 1000 can be abstracted as the process of the display panel protective bracket separating around the auxiliary support surface 510 of the tearing aid 500. The tendency of the display panel protective bracket to rotate around the auxiliary support surface 510 is greater than the involute tendency to rotate around the display panel 1000. Assuming that the involute rotation around the display panel 1000 is understood as the boundary of stress-free separation, then in order to reduce the pressure of the display panel protective bracket on the display panel 1000 during the tearing process, the separation of the display panel protective bracket from the display panel 1000 needs to become faster and faster. To make the separation of the display panel protective bracket from the display panel 1000 faster and faster, the curvature of the display panel protective bracket rotating around the auxiliary support surface 510 can be made larger and the radius of curvature smaller and smaller. Figure 5 and Figure 6 As shown, the auxiliary support surface 510 is an arc-shaped surface that extends in the tearing direction and gradually moves away from the back of the display panel 1000. When the display panel protective bracket rotates around the arc-shaped surface that serves as the auxiliary support surface 510, the contact between the arc-shaped surface and the back of the display panel 100 is a "surface contact" and the contact position changes continuously. Therefore, the force exerted by the display panel protective bracket on the back of the display panel 1000 is dispersed by the arc-shaped surface and applied to different positions on the back of the display panel 1000. Thus, the pressure exerted by the display panel protective bracket on the back of the display panel 1000 during the tearing process can be reduced to a large extent, thereby effectively avoiding the occurrence of printing problems.

[0062] It should be noted that the display panel protective bracket is applied to the display panel 1000 by hand, whether it is flat or curved. The display panel protective bracket proposed in this application can meet the requirements of manual application, and the application operation is simple and convenient.

[0063] As an alternative implementation method, such as Figure 7 and Figure 9 As shown, a support buffer layer 420 is provided on the positioning support surface 410.

[0064] In the embodiments of this application, such as Figure 7 and Figure 9 As shown, the support buffer layer 420 can be made of cushioning materials such as foam, and can be attached to the positioning support surface 410 using adhesives such as double-sided tape. The support buffer layer 420 provides cushioning for the positioning support surface 410, preventing the positioning support surface 410 of the support part 400 from damaging the display panel 1000. The adhesive can be a strong adhesive with a strength of 1000 gf / inch to 1200 gf / inch, for example, 1000 gf / inch, 1100 gf / inch, 1200 gf / inch, etc. Choosing a strong adhesive with high tack ensures a firm bond between the support buffer layer 420 and the positioning support surface 410, preventing the support buffer layer 420 from detaching.

[0065] As an alternative implementation method, such as Figures 5 to 10 As shown, the display panel protective bracket also includes a side shield 600, which is disposed on the shield 100 and extends toward the display panel 1000. The side shield 600 shields the bonding area 1100 located at the end of the display panel 1000.

[0066] In the embodiments of this application, the bonding area 1100 of the display panel 1000 is the area where the flexible circuit board is flipped and bent from the front of the display panel 1000 to the back of the display panel 1000, so there is a portion of the bonding area 1100 at the end of the display panel 1000.

[0067] In the display panel protective bracket of this application, such as Figure 6 and Figure 8 As shown, a side shield 600 is provided on the shielding portion and extends towards the display panel 1000. The side shield 600 shields the bonding area 1100 located at the end of the display panel 1000, preventing the bonding area 1100 at the end of the display panel 1000 from being damaged by impact. Optionally, the side shield 600 extends to a position flush with or protruding from the horizontal plane of the front of the display panel 1000, thereby ensuring that the side shield 600 can completely shield the bonding area 1100 at the end of the display panel 1000, ensuring a good protective effect for the bonding area 1100 at the end of the display panel 1000.

[0068] As an alternative implementation method, such as Figures 5 to 8 As shown, the support part 400 is located on the side of the tearing auxiliary part 500 opposite to the tearing direction.

[0069] In a display panel protective bracket, if the support portion 400 is located on the side of the tear-off aid portion 500 that is in the same tear-off direction, for example in... Figure 6In the display panel protective bracket shown, the support part 400 is located to the right of the tear-off auxiliary part 500. When the display panel protective bracket is torn off the display panel 1000, the display panel protective bracket will be lifted off the display panel 1000 with the tear-off auxiliary part 500 and the support part 400 as supports in turn. The support part 400 will exert a large force on the display panel 1000, which may damage the display panel 1000.

[0070] In the embodiments of this application, such as Figures 5 to 8 As shown, the support part 400 is positioned on the side opposite to the tearing direction of the tearing aid part 500. When the display panel protective bracket is torn off from the display panel 1000, since the direction of the support part 400 relative to the tearing aid part 500 is opposite to the tearing direction, the support part 400 first leaves the display panel 1000 synchronously with one end of the display panel protective bracket. This can prevent the support part 400 from being damaged by force on the display panel 1000 during tearing.

[0071] As an alternative implementation method, such as Figure 5 and Figure 6 As shown, the tear-off auxiliary part 500 and the bonding part 300 are integral structures and extend from the bonding part 300 in the tear-off direction; the bonding buffer layer 320 and the auxiliary buffer layer 520 are integral structures.

[0072] In the embodiments of this application, such as Figure 5 and Figure 6 This design allows the peeling aid 500 and the bonding part 300 to be integrated into a single structure, as well as the bonding buffer layer 320 and the auxiliary buffer layer 520. This not only simplifies the overall structure of the display panel protective bracket but also allows for the simultaneous installation of the bonding buffer layer 320 and the auxiliary buffer layer 520, reducing operational steps. Furthermore, it makes the rotation process around the peeling aid 500 during peeling smoother and more efficient, avoiding excessive pressure on the display panel 1000 and thus preventing mold marks.

[0073] As an alternative implementation, the display panel protective bracket includes at least two tear-off aids 500.

[0074] In the embodiments of this application, two or more tear-off auxiliary parts 500 can be provided according to the fragility of the display panel 1000 and the structural requirements of the display panel 1000. The force applied to the display panel 1000 during tearing can be dispersed by multiple tear-off auxiliary parts 500, so as to avoid excessive local pressure on the back of the display panel 1000 and the resulting molding problem.

[0075] For example, a tear-off auxiliary part 500 can be provided in both the bonding part 300 and the connecting part 200. The structure of the two tear-off auxiliary parts 500 can be adaptively adjusted according to their different positions, so as to disperse the force generated on the back of the display panel 1000 when the display panel protective bracket is torn off.

[0076] As an alternative implementation method, such as Figures 9 to 11 As shown, the bonding buffer layer 320 protrudes at least a predetermined distance in the tearing direction relative to the bonding portion 300.

[0077] In the embodiments of this application, such as Figures 9 to 11 As shown, the bonding buffer layer 320 extends at least a predetermined distance in the tearing direction relative to the bonding portion 300, so that when the display panel protective bracket is torn off, the bonding buffer layer 320 can pad between the side of the bonding portion 300 in the tearing direction and the display panel 1000, avoiding direct contact between the side of the bonding portion 300 and the display panel 1000, which would cause damage to the display panel 1000 and mold marks.

[0078] In the display panel protective bracket of this application, the bonding buffer layer 320 is not limited to protruding outward relative to the bonding portion 300 only in the tear-off direction, but can also protrude outward relative to the bonding portion 300 on all sides, so that even if the bonding portion 300 is in a direction parallel to the plane where the display panel 1000 is located, the bonding buffer layer 320 can padded between the bonding portion 300 and the display panel 1000.

[0079] As a further optional implementation, such as Figures 9 to 11 As shown, the preset distance is 2 to 5 times the thickness of the 300mm bonding part.

[0080] In the embodiments of this application, in order to ensure that the bonding buffer layer 320 can be padded in the direction parallel to the plane of the bonding portion 300 and the display panel 1000, the preset distance is 2 to 5 times the thickness of the bonding portion 300. For example, the preset distance can be 2, 3, 4, or 5 times the thickness of the bonding portion 300, that is, the bonding buffer layer 320 is at least 2 to 5 times the thickness of the bonding portion 300. For example, if the thickness of the bonding portion 300 is 1.2 mm, then the bonding buffer layer 320 is expanded by 2 times, which is 2.4 mm; the bonding buffer layer 320 is expanded by 3 times, which is 3.6 mm; the bonding buffer layer 320 is expanded by 4 times, which is 4.8 mm; and the bonding buffer layer 320 is expanded by 5 times, which is 6.0 mm. It should be noted that the preset distance by which the bonding buffer layer 320 expands outward relative to the bonding portion 300 does not necessarily have to be an integer multiple of the thickness of the bonding portion 300. For example, the preset distance by which the bonding buffer layer 320 expands outward can be 3.0 mm.

[0081] In the embodiments of this application, such as Figures 9 to 11 As shown, the first adhesive layer 310 and the second adhesive layer 330 are designed to be recessed relative to the bonding portion 300, meaning that the first adhesive layer 310 and the second adhesive layer 330 can be recessed by 0.3mm to 1.0mm relative to the bonding portion 300. For example, the first adhesive layer 310 and the second adhesive layer 330 can be recessed by 0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.0mm, etc. The recessed first adhesive layer 310 can prevent it from being pasted in any location other than the bonding buffer layer 320, thus avoiding interference with the removal of the display panel protective bracket. Similarly, the recessed second adhesive layer 330 can reduce the area pasted with the display panel 1000, reducing the force required to peel the display panel protective bracket from the display panel 1000.

[0082] As a further optional implementation, such as Figure 9 and Figure 10 As shown, the bonding part 300 can adopt a rounded head structure in the tear-off direction, and the sides of the rounded head of the bonding part 300 are all arc-shaped, so as to avoid the bonding part 300 exerting too much pressure on the display panel 1000 and causing damage to the display panel 1000.

[0083] It should be noted that in the display panel protective bracket of the above embodiments of this application, in order to enable the bonding part 300, the support part 400 and the tear-off auxiliary part 500 of the display panel protective bracket to bond or abut against the display panel 1000 after various buffer layers are respectively provided, it is necessary to adaptively adjust the height of the bonding part 300, the support part 400 and the tear-off auxiliary part 500 relative to the shielding part 100 according to the thickness of various buffer layers, so that the height of the bonding part 300, the support part 400 and the tear-off auxiliary part 500 relative to the shielding part 100 is the same after various buffer layers are provided, so that the surfaces of the bonding part 300, the support part 400 and the tear-off auxiliary part 500 used to bond / abut against the display panel 1000 after various buffer layers are provided are in the same horizontal plane.

[0084] In the display panel protective bracket of the above embodiments of this application, the thickness of the first adhesive layer 310, the second adhesive layer 330 and the auxiliary adhesive layer 530 is relatively small compared with the thickness of various buffer layers. Therefore, the thickness of the first adhesive layer 310, the second adhesive layer 330 and the auxiliary adhesive layer 530 in the display panel protective bracket can be ignored.

[0085] It should be noted that in the display panel protective bracket of the above embodiments of this application, since the bonding part 300, the support part 400 and the auxiliary tear-off part need to contact the back of the display panel 1000, the positions of the bonding part 300, the support part 400 and the auxiliary tear-off part relative to the blocking part 100 need to be adaptively adjusted according to the positions of the bonding area 1100 and the integrated circuit chip 1200, so that the bonding part 300, the support part 400 and the auxiliary tear-off part avoid the bonding area 1100 and the integrated circuit chip 1200 of the display panel 1000, and avoid the bonding part 300, the support part 400 and the auxiliary tear-off part from putting pressure on the bonding area 1100 and the integrated circuit chip 1200, which would cause damage to the bonding area 1100 and the integrated circuit chip 1200.

[0086] It should be noted that in the display panel protective bracket of the above embodiments of this application, various buffer layers can be formed at corresponding positions of the bonding portion 300, the support portion 400, and the peel-off auxiliary portion 500 using a relatively soft material and a two-color injection molding process. That is, the various buffer layers are integrally molded at the corresponding positions of the bonding portion 300, the support portion 400, and the peel-off auxiliary portion 500 using a two-color injection molding process, avoiding the labor costs of re-attaching various buffer layers. In addition, by integrally molding various buffer layers at the corresponding positions of the bonding portion 300, the support portion 400, and the peel-off auxiliary portion 500 using a two-color injection molding process, the display panel protective bracket can be reused after being peeled off from the display panel 1000. When reused, only the second adhesive layer 330 and the release protective film 340 of the bonding portion 300 need to be reset, which can significantly reduce the usage cost of the display panel protective bracket.

[0087] Based on the same inventive concept, this application embodiment also provides a display panel 1000, which includes a display panel 1000 body and the aforementioned display panel protective bracket, wherein the fitting portion 300 of the display panel protective bracket is fitted to the back of the display panel 1000; the positioning support surface 410 of the support portion 400 abuts against the back of the display panel 1000; and the auxiliary support surface 510 abuts against the back of the display panel 1000.
