[0002] Display panels are widely used in electronic devices such as notebooks, mobile phones, display screens, etc. The substrate of a display panel is usually connected to a related circuit board. In related technologies, a tape with a release film is usually attached to the substrate, and then the release film is removed, and a related circuit board is attached to the side of the tape where the release film has been removed to achieve the connection between the substrate and the related circuit board.

[0003] However, before attaching the related circuit board, it is easy for an operator to collide with the release film, causing the release film to separate from the tape, resulting in the loss of adhesion or contamination of the area on the tape for attaching the related circuit board, thereby causing poor connection between the substrate and the related circuit board.

[0069] To make the above - mentioned objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application.

Therefore, it should not be construed as a limitation to the present application.

[0071] In addition, if there appear such terms as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there appears the term "plural", the meaning of "plural" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0075] Figure 1 The structural schematic diagram of the tape structure in an embodiment of the related art is shown; Figure 2 The schematic diagram when the tape structure in an embodiment of the related art is collided is shown; for the convenience of description, only the content related to the embodiment of the related art is shown.

[0076] In an embodiment of the related art, please refer to Figure 1 , the tape structure 10 includes a tape body 11 and a release film 12. The tape body 11 includes a main body portion 111 and a handle portion 112 connecting the main body portion 111. The release film 12 includes a connecting portion (since the connecting portion is blocked by the handle portion 112, so Figure 1 and Figure 2The handle 112 is provided on the adhesive surface of the handle 112. In the process of manufacturing the display panel, the operator needs to adhere the adhesive surface of the main body 111 of the tape body 11 to the edge of one side of the substrate of the display panel, and make the handle 112 outside the substrate so that the handle 112 can be connected to the relevant circuit board in the subsequent process. Since the handle 112 extends outside the substrate and the release film 12 is provided on the handle 112 of the tape body 11, it is easy for the operator to collide with the tearing portion 122 of the release film 12 during the process of manufacturing the display panel (the collision direction can be Figure 1 and Figure 2 The collision may cause the handle portion 112 to bend relatively greatly, and the deflection is transmitted to the connection portion, which may easily cause the connection portion to separate from the handle portion 112, and further cause the release film 12 to separate from the tape body 11, which may cause the adhesive surface of the tape body 11 to lose its stickiness or be contaminated, causing problems in the connection between the tape body 11 and the substrate and related circuit boards, thereby causing poor connection between the substrate of the display panel and the related circuit boards.

[0077] The inventor of this application has noted that please refer to Figure 2 In an embodiment of the related art, when the operator collides with the release film 12, the collision causes the tearing portion 122 of the release film 12 to be relatively greatly bent to form a fold line area A, and the fold line area A has a reverse fold line L, and the reverse fold line L is parallel to the reference direction X (such as Figure 1 and Figure 2 The fold line L corresponds to the stress transmitted to the connection end 1221 of the tear-off portion 122, and the larger the fold area A is, the longer the fold line L is, the greater the stress acting on the connection portion is, and the greater the reaction force of the connection portion on the operator is, which makes it easier to separate the connection portion and the handle portion 112. Figure 1 The handle portion 112 has a handle edge 1121 facing away from the main body portion 111 , and the reference direction is the extending direction of the handle edge 1121 .

[0078] Figure 3 A structural schematic diagram of the tape structure in an embodiment of the present application is shown; for ease of explanation, only the content related to the embodiment of the present application is shown.

[0079] For this purpose, see Figure 3 In some embodiments, the present application provides a tape structure 20, including a tape body 21 and a release film 22, the tape body 21 includes a main body 211 and a handle 212 connected to the main body 211, the release film 22 includes a connecting portion 221 and a tearing portion 222 connected to the connecting portion 221, the connecting portion 221 is provided on the adhesive surface a1 of the handle 212 (the adhesive surface a1 can be combined with the adhesive surface shown in the following reference) Figure 7and Figure 9 ). The tear-off portion 222 has a connection end 2221 connected to the connection portion 221; the tear-off portion 222 is provided with a stress dispersion structure 2222, and the stress dispersion structure 2222 can suppress the connection end 2221 of the tear-off portion 222 from bending.

[0080] Please refer to Figure 3 The main body 211 refers to the portion where the tape body 21 is bonded to the panel body 31 of the display panel 30 (the display panel 30 and the panel body 31 can be combined with the reference hereinafter schematically shown). Figure 7 and Figure 9 The panel body 31 is also the substrate mentioned in the background technology. The structure of the main body 211 can be set as needed. For example, the main body 211 can be constructed to be along the reference direction X (such as Figure 3 A rectangular structure extending in the X direction (as shown in FIG. 1 ).

[0081] The handle portion 212 refers to the portion of the tape body 21 connected to the main body 211, and the handle portion 212 is protruding and arranged on one side of the main body 211. The size of the handle portion 212 along the reference direction is smaller than the size of the main body 211 along the reference direction. The handle portion 212 is provided to bond the system-side circuit board 40 connected to the display panel 30 (the display panel 30 and the system-side circuit board 40 can be combined with the reference diagram shown later). Figure 9 ), that is, the handle portion 212 is a protruding structure arranged as needed.

[0082] The tearing portion 222 refers to a gripping portion provided for the convenience of an operator in tearing off the release film 22 . To facilitate tearing off the release film 22 , the release film 22 is extended in a direction perpendicular to the reference direction for easy gripping.

[0083] The stress dispersion structure 2222 refers to a structure capable of dispersing the stress generated by the tear-off portion 222 when it is hit. The shape and structure of the stress dispersion structure 2222 are not limited as long as the stress of the tear-off portion 222 can be dispersed. Suppression means that the stress dispersion structure 2222 can partially reduce the deflection generated by the tear-off portion 222, or partially block the transmission of the deflection generated by the tear-off portion 222, thereby reducing the stress of the tear-off portion 222, thereby reducing the deflection amplitude of the connection end 2221 of the tear-off portion 222.

[0084] In some embodiments, the Figure 7, the tape body 21 includes a protective film 21a and an adhesive layer 21b provided on one side of the protective film 21a, and the release film 22 is provided on the surface of the adhesive layer 21b facing away from the protective film 21a. It can be understood that, from the perspective of the connection relationship, the tape body 21 includes a main body portion 211 and a handle portion 212. From the perspective of the structural composition, the tape body 21 includes a protective film 21a and an adhesive layer 21b. That is, the protective film 21a and the adhesive layer 21b originally divided according to the lamination relationship are divided into a main body portion 211 and a handle portion 212 according to the connection relationship of the tape body 21.

[0085] It should be noted that, with reference to Figure 7 , the surface of the adhesive layer 21b facing away from the protective film 21a is the first surface B, and the first surface B is the adhesive surface a1.

[0086] In this way, the tape structure 20 of the present application at least includes a tape body 21 and a release film 22. By providing a stress dispersion structure 2222 on the tearing portion 222 of the release film 22, since the stress dispersion structure 2222 can inhibit the flexure of the connection end 2221 of the tearing portion 222, it is possible to reduce the flexure transmitted from the tearing portion 222 to the connection portion 221. In this way, the situation where the release film 22 is separated from the tape body 21 due to the collision of the operator can be improved, so as to minimize the occurrence of the tape body 21 losing its adhesiveness or being contaminated due to the loss of the protection of the release film 22, which is beneficial to the good connection between the substrate and the relevant circuit board.

[0087] Comparing the related art and the tape structure 20 in the present application, with reference to Figure 3 , if the stress dispersion structure 2222 is not provided on the tearing portion 222 of the tape structure 20 of the present application, when the operator collides with the tearing portion 222 of the release film 22, the collision will cause a relatively large flexure of the tearing portion 222, and this flexure is transmitted to the connection end 2221 of the tearing portion 222, which is likely to cause the connection portion 221 of the release film 22 to be separated from the handle portion 212 of the tape body 21, resulting in the loss of adhesiveness or contamination of the area on the tape for pasting the relevant circuit board, thus causing poor connection between the substrate and the relevant circuit board; after the stress dispersion structure 2222 is provided on the tearing portion 222 of the present application, the stress dispersion structure 2222 can reduce the stress on the tearing portion 222 to reduce the stress transmitted to the connection end 2221, which can improve the separation situation between the connection portion 221 and the handle portion 212 to a certain extent.

[0088] In some embodiments, please continue to refer to Figure 3, the stress dispersion structure 2222 is configured to enable the tearing portion 222 to form a weak segment 2223. The weak segment 2223 has a weak edge e1 arranged along the reference direction. The stress dispersion structure 2222 is located on the side of the weak segment 2223 where the weak edge e1 is provided. Among them, the handle portion 212 has a handle edge b1 facing away from the main body portion 211, and the reference direction is the extending direction of the handle edge b1.

[0089] It should be noted that, please continue to refer to Figure 3 , the weak segment 2223 refers to the part of the tearing portion 222 that can withstand less external force compared to other parts of the tearing portion 222. When the tearing portion 222 is subjected to an external force, the external force will be preferentially dispersed to the weak segment 2223. In the embodiment of the present application, the weak segment 2223 is formed by setting the stress dispersion structure 2222 on the tearing portion 222. The flexure on the weak segment 2223 caused by collision is smaller than the flexure of other parts of the tearing portion 222. In order to form the weak segment 2223, the stress dispersion structure 2222 can be any shape of holes, through slots and other structures, or can also be a cut incision. The weak segment 2223 has two side edges along the reference direction, and at least one of these two side edges is the weak edge e1. The weak edge e1 refers to the side edge of the weak segment 2223 along the reference direction between the weak segment 2223 and the stress dispersion structure 2222. If both side edges of the weak segment 2223 along the reference direction are located between the stress dispersion structure 2222 and the weak segment 2223, then both side edges are the weak edge e1.

[0090] In some embodiments, please continue to refer to Figure 3 , the weak edge e1 is arranged at an angle with the reference direction X.

[0091] It should be noted that, please continue to refer to Figure 3 , being arranged at an angle means that the extending direction of the weak edge e1 is not parallel to the reference direction X. That is, there is an included angle between the extending direction of the weak edge e1 and the reference direction X. Such a setting is to enable the tearing portion 222 to form a weak segment 2223, and the flexure on the weak segment 2223 caused by collision is smaller. That is, the stress on the weak segment 2223 is smaller, so that the stress transmitted from the weak segment 2223 to the connection end 2221 is smaller. In this way, it is more difficult for the connection portion 221 and the handle portion 212 to separate.

[0092] In other embodiments, please continue to refer to Figure 3, the minimum dimension of the weak segment 2223 along the reference direction X is smaller than the maximum dimension of the tearing portion 222 along the reference direction X. It can be understood that the smaller the dimension along the reference direction X, the smaller the fold line area caused by flexure (the fold line area and the reverse fold line are not shown in the drawings of the embodiments of the present application), and the shorter the reverse fold line, so that the stress transmitted to the connection end 2221 is smaller, which is beneficial to reducing the risk of separation between the connection portion 221 and the handle portion 212.

[0093] In this way, by providing the stress dispersion structure 2222 on the tearing portion 222, the tearing portion 222 forms a weak segment 2223 having a weak edge e1, and the weak edge e1 is arranged at an angle with the extending direction of the handle edge b1. The minimum dimension of the weak segment 2223 along the reference direction X is smaller than the maximum dimension of the tearing portion 222 along the reference direction X. When the tearing portion 222 is collided, the weak segment 2223 generates flexure first. Since the dimension of the weak segment 2223 is relatively small, the fold line area caused by the flexure of the weak segment 2223 is also small, and the stress is relatively reduced. This makes the stress dispersed from the weak segment 2223 to the connection end 2221 small, thereby improving the separation situation between the connection portion 221 and the handle portion 212.

[0094] In some embodiments, please continue to refer to Figure 3 , the stress dispersion structure 2222 is configured to make the tearing portion 222 a discontinuous structure; the tearing portion 222 includes a plurality of tearing sub-portions 2224, and one ends of all the tearing sub-portions 2224 connected to the connection portion 221 are independent of each other; the stress dispersion structure 2222 is formed between two adjacent tearing sub-portions 2224 along the reference direction X; the tearing sub-portions 2224 constitute the weak segment 2223.

[0095] It should be noted that, please continue to refer to Figure 3 , the discontinuous structure means that the tearing portion 222 is not a complete structure, and there is no connection relationship between at least some parts of the tearing portion 222, and they can be separated from each other or independent of each other. For example, the connection end 2221 of the tearing portion 222 can be arranged into at least two separated parts along the reference direction X. For another example, one end of the tearing portion 222 away from the connection end 2221 can be arranged into at least two separated parts along the reference direction X. For yet another example, the connection end 2221 of the tearing portion 222 can be arranged into at least two separated parts along the reference direction X, and one end of the tearing portion 222 away from the connection end 2221 can be arranged into at least two separated parts along the reference direction X. Independent of each other means that there is no connection relationship between one ends of all the tearing sub-portions 2224 connected to the connection portion 221, and they are in a separated state from each other.

[0096] Thus, by setting the tearing portion 222 into a plurality of tearing sub-portions 2224, and all the tearing sub-portions 2224 are connected to one end of the connecting portion 221 independently of each other, at least partially blocking the flexure generated by the collided tearing sub-portion 2224 from being transmitted to other tearing sub-portions 2224, thereby reducing the tearing sub-portions 2224 that undergo flexure, and thus being able to reduce the stress transmitted to the connection end 2221.

[0097] In some embodiments, please continue to refer to Figure 3 , all the tearing sub-portions 2224 are independent of each other. That is, the stress dispersion structure 2222 penetrates through the tearing portion 222 in a direction set at an angle to the reference direction X.

[0098] Thus, by setting all the tearing sub-portions 2224 to be independent of each other, further blocking the flexure generated by the collided tearing sub-portion 2224 from being transmitted to other tearing sub-portions 2224, thereby further reducing the tearing sub-portions 2224 that undergo flexure, so as to be able to further reduce the stress transmitted to the connection end 2221.

[0099] In some embodiments, please continue to refer to Figure 3 , the stress dispersion structure 2222 has a starting end c1 and a terminating end c2. The starting end c1 is located at the connection end 2221, and the stress dispersion structure 2222 extends linearly between the starting end c1 and the terminating end c2.

[0100] It should be noted that, please continue to refer to Figure 3 , the starting end c1 refers to the end of the stress dispersion structure 2222 close to the connection end 2221, and the terminating end c2 refers to the end of the stress dispersion structure 2222 away from the connection end 2221. Thus, by setting the stress dispersion structure 2222 to extend linearly between the starting end c1 and the terminating end c2, so as to form the tearing sub-portions 2224 on the tearing portion 222.

[0101] In some embodiments, please continue to refer to Figure 3 , the extending direction of the stress dispersion structure 2222 is perpendicular to the reference direction X.

[0102] Thus, by setting the extending direction of the stress dispersion structure 2222 to be perpendicular to the reference direction X, so that the dimension of the same tearing sub-portion 2224 in the reference direction X always remains the same, thereby being beneficial to better dispersing the stress generated by the tearing portion 222.

[0103] In some embodiments, please continue to refer to Figure 3, a plurality of stress dispersion structures 2222 are provided, and all the stress dispersion structures 2222 are arranged at intervals along the reference direction X. It can be understood that the number of stress dispersion structures 2222 can be set according to the size of the tearing portion 222 along the reference direction X. That is, the larger the size of the tearing portion 222 along the reference direction X, the more stress dispersion structures 2222 can be set, so as to form more tearing sub-portions 2224, thereby reducing the size of the tearing sub-portions 2224 along the reference direction X, so as to reduce the area of the folded line region caused by the flexure generated by the tearing sub-portions 2224, and further reducing the length of the reverse fold line, so that the stress transmitted to the connection end 2221 is also reduced.

[0104] In some embodiments, please continue to refer to Figure 3 , all the stress dispersion structures 2222 are arranged at equal intervals along the reference direction X. In this way, the sizes of all the tearing sub-portions 2224 along the reference direction X are the same, which is beneficial to better disperse the stress generated by the tearing portion 222 due to collision, thereby being beneficial to reducing the stress transmitted to the connection end 2221 to improve the separation situation between the connection portion 221 and the handle portion 212.

[0105] In some embodiments, please continue to refer to Figure 3 , the stress dispersion structure 2222 is a slit d1 provided on the tearing portion 222. For example, a slit d1 can be provided at the connection end 2221 of the tearing portion 222, and the slit d1 can be one or more. For another example, a slit d1 can be provided at the end of the tearing portion 222 facing away from the connection end 2221, and the slit d1 can be one or more. For yet another example, at least two slits d1 can be provided at intervals along the reference direction X on the tearing portion 222, where at least one slit d1 is provided at the connection end 2221, and at least another slit d1 is provided at the end of the tearing portion 222 facing away from the connection end 2221.

[0106] In some embodiments, please continue to refer to Figure 3 , the size of the stress dispersion structure 2222 along the reference direction X is 0.6 mm to 1 mm, and the size of the stress dispersion structure 2222 along the reference direction X is denoted as the first dimension D. It can be understood that the size of the stress dispersion structure 2222 along the reference direction X can also be set as required.

[0107] It should be noted that when the size of the stress dispersion structure 2222 along the reference direction X is between 0.6 mm and 1 mm, it is more beneficial to reduce the reaction force generated at the connection end 2221, thereby being able to improve the separation situation between the connection portion 221 and the handle portion 212.

[0108] Figure 4 shows a schematic structural diagram of a tape structure in another embodiment of the present application; Figure 5 shows a schematic structural diagram of a tape structure in yet another embodiment of the present application;Figure 6 The structural schematic diagram of the tape structure in another embodiment of the present application is shown; for ease of description, only the content related to the embodiments of the present application is shown.

[0109] In some embodiments, referring to Figures 4 to 6 , the tearing portion 222 includes a weak section 2223 and a flexure section 2225. The weak section 2223 is connected between the connecting portion 221 and the flexure section 2225. One end of the weak section 2223 connected to the connecting portion 221 is a connecting end 2221.

[0110] It should be noted that the flexure section 2225 refers to the part of the tearing portion 222 that an operator collides with.

[0111] In some embodiments, please continue to refer to Figure 4 , the stress dispersion structure 2222 is a through hole d2 provided in the weak section 2223. Optionally, the through hole d2 is configured as a rectangle, and the through hole d2 is provided on the handle side b1. It can be understood that the shape of the through hole d2 is not limited to a rectangle, and it can also be set to other shapes as long as the requirements are met.

[0112] In this way, by setting the stress dispersion structure 2222 as the through hole d2 provided in the weak section 2223 to reduce the size of the weak section 2223 along the reference direction X, when the tearing portion 222 is collided, the folded line area of the weak section 2223 can be reduced, which is beneficial to suppressing the flexure of the connecting end 2221.

[0113] In some embodiments, please continue to refer to Figure 5 , the weak edge e1 includes a first sub-edge e2 and a second sub-edge e3 that are oppositely arranged along the reference direction X; the stress dispersion structure 2222 is a notch d3 provided on at least one of the first sub-edge e2 and the second sub-edge e3. It can be understood that the stress dispersion structure 2222 can be provided on the first sub-edge e2 or the second sub-edge e3 alone, or the stress dispersion structure 2222 can be provided on both the first sub-edge e2 and the second sub-edge e3. The first sub-edge e2 and the second sub-edge e3 can be interchanged, and it is not necessarily the Figure 5 position shown in. In order to further reduce the area of the folded line area formed on the weak section 2223, the stress dispersion structure 2222 can be provided on both the first sub-edge e2 and the second sub-edge e3. For example, referring to Figure 5 , one notch d3 is provided on each of the first sub-edge e2 and the second sub-edge e3. Each notch d3 penetrates the tearing portion 222 along the reference direction X in a direction away from the other notch d3. The opposite two side edges of the notch d3 along the direction perpendicular to the reference direction X are symmetrically arranged and are both arranged at an angle to the reference direction X, so as to Figure 5 take the markings in as an example, along Figure 5In the second sub-edge e3, the direction pointing to the first sub-edge e2, the dimension of the notch d3 in the direction perpendicular to the reference direction X shows a decreasing trend, and shows a linear decreasing trend.

[0114] In this way, by setting the stress dispersion structure 2222 as the notch d3 provided on the weak edge e1 to reduce the dimension of the weak section 2223 in the reference direction X, when the tearing part 222 is collided, the broken line area of the weak section 2223 can be reduced, which is beneficial to suppressing the flexure of the connection end 2221.

[0115] In some embodiments, please continue to refer to Figures 3 to 5 , the tearing part 222 is arranged on the handle edge b1 of the handle part 212. That is, the handle part 212 is located between the main body part 211 and the tearing part 222.

[0116] In some embodiments, please continue to refer to Figure 6 , the handle part 212 has a first side b2 and a second side b3 oppositely arranged along the reference direction X, and the first side b2 and the second side b3 are respectively connected between the main body part 211 and the handle edge b1. It can be understood that the positions of the first side b2 and the second side b3 can be interchanged and are not necessarily the Figure 6 positions shown in. Among them, in some embodiments, the tearing part 222 is arranged on the first side b2 of the handle part 212 (the drawings corresponding to this embodiment are not shown in the present application); in other embodiments, the tearing part 222 is arranged on the second side b3 of the handle part 212 (reference can be made to Figure 6 ). That is, the tearing part 222 can be arranged alone on the first side b2 or the second side b3. In these embodiments, the connecting part 221 and the tearing part 222 are arranged along the reference direction X. For example, referring to Figure 6 , the notch d3 is arranged on the side of the tearing part 222 close to the tape body 21 along the reference direction X, and the shape of the notch d3 is the same as the Figure 5 shape of the notch d3 in, so it will not be elaborated here.

[0117] It can be understood that when the stress dispersion structure 2222 is the notch d3, the specific shape of the notch d3 is not limited to the Figure 5 and Figure 6 shapes shown, and can also be other shapes.
