The application is described below with reference to specific embodiments in conjunction with the following drawings:
the periphery of a Liquid Crystal Display (LCD) module needs to be adhered with an adhesive Tape (Cell Tape), which has the functions of reinforcing the LCD module, preventing electromagnetic interference or light leakage, etc. However, the adhesive tape generally includes an adhesive tape body 110 and a release film layer stacked on the adhesive surface of the adhesive tape body 110, the release film layer is removed for attachment when the adhesive tape 100 is attached, since the adhesive tape body 110 is soft, the attachment operation can only be performed by manual alignment, the adhesive tape 100 is easily attached to the upper side of the Polarizer 300(Polarizer, POL) or poor wrinkles are generated, and the subsequent processes have limited interception rates for such defects and poor interception, which leads to product quality problems and further leads to customer complaints.
To solve the problems of the above adhesive tape, as shown in fig. 1, an embodiment of the present invention provides an adhesive tape 100, where the adhesive tape 100 is used for being attached to a liquid crystal display module 200 having a polarizer 300, and the adhesive tape 100 includes:
the tape body 110, the adhesive surface of the tape body 110 is used for being attached to the liquid crystal display module 200, and the tape body 110 has a contact edge 111 connected with the polarizer 300;
a reinforcing layer 130 laminated on the non-adhesive surface of the tape body 110;
wherein the reinforcing layer 130 has a hardness greater than that of the tape body 110.
The adhesive tape 100 of the embodiment of the present application has a reinforcing layer 130 on the non-adhesive surface of the adhesive tape body 110,
in the adhesive tape 100 of the embodiment of the present application, the reinforcing layer 130 is additionally disposed on the non-adhesive surface of the adhesive tape body 110, and the hardness of the reinforcing layer 130 is greater than that of the adhesive tape body 110. The reinforcing layer 130 is additionally arranged to improve the overall hardness of the adhesive tape 100, so that the adhesive tape 100 has certain stiffness and smoothness, the adhesive tape 100 laminated with the reinforcing layer 130 is conveniently and integrally attached to the liquid crystal display module 200, wrinkles caused by factors such as softness of the adhesive tape 100 during attachment are avoided, the stiffness and smoothness of the adhesive tape 100 can also facilitate the positioning of the contact edge 111 of the adhesive tape 100 relative to the polarizer 300, and the phenomenon that the adhesive tape body 110 is attached to the upper side of the polarizer 300 due to inaccurate positioning caused by the fact that the adhesive tape 100 is too soft is avoided, the reject ratio of products is reduced, reworking is reduced, and the qualification rate of the products is improved; further, in the attaching process of the adhesive tape 100, the contact edge 111 contacts the polarizer and bonds the adhesive surface of the adhesive tape body 110 with the upper surface of the liquid crystal display module 200, the rest part of the adhesive tape 100 is bent to bond the adhesive surface of the adhesive tape body 110 with the side surface of the liquid crystal display module 200, because the hardness of the reinforcing layer 130 is greater than that of the adhesive tape body 110, the bent adhesive tape body 110 is bonded on the side surface of the liquid crystal display module 200 through the adhesive surface, and the reinforcing layer 130 has a certain force of recovering the original shape under the action of the hardness of the reinforcing layer 130, so that the reinforcing layer 130 is automatically separated from the adhesive tape body 110 at the bent part, the additionally arranged reinforcing layer 130 is conveniently removed from the adhesive-free surface of the adhesive tape body 110, and the difficulty of the attaching operation is effectively reduced.
As an alternative embodiment, as shown in fig. 1, the adhesive tape 100 further includes: a protective layer 120 laminated on the adhesive surface of the tape body 110.
The protective layer 120 mainly serves to protect the adhesive surface of the tape body 110, prevent the adhesive surface from being scratched or contaminated to affect the adhesive property of the adhesive surface, and is attached immediately after the protective layer 120 is removed when the tape 100 is attached. In this embodiment, the material of the protective layer 120 is not limited, and the hardness, strength, and the like of the protective layer are not specifically required, and the purpose of protecting the adhesive surface can be satisfied. For example, it may be a polyphenylene ether release film, a polytetrafluoroethylene release film, a polyethylene release film, a composite release film, or the like.
As an alternative embodiment, the strength of the reinforcing layer 130 is greater than the strength of the tape body 110. The reinforcing layer 130 mainly functions to improve the hardness of the tape body 110, further improve the strength of the tape body 110, prevent the tape body 100 from being easily curled to generate wrinkles when being attached, prevent the tape body from being easily positioned and attached to the upper side surface of the polarizer 300, and prevent the tape body 110 from being broken due to low strength when being attached, thereby effectively avoiding the problems of heavy industry, customer complaints, and the like.
Further, the market end prefers to a narrow frame model, which results in the effective attaching area of the front surface of the liquid crystal display module 200 becoming narrower and narrower, and the requirement for the attaching operation becoming higher and higher. In the above embodiment, the material of the reinforcement layer 130 preferably has a hardness and strength greater than those of the tape body 110, and the specific material thereof can be selected according to the requirement. For example, it may be a polyphenylene ether release film, a polytetrafluoroethylene release film, a polyethylene release film, a composite release film, or the like. Optionally, the hardness of the release film is selected according to specific application requirements, and when the adhesive tape is attached, the reinforcing layer 130 can be bent under the action of external force, and can also have a certain action force to enable the reinforcing layer to recover without the action of external force. As an optional implementation manner, in this embodiment, the shore D hardness of the release film selected for the reinforcing layer 130 is 50 to 32, and the tensile strength is 17.0Mpa or more, which can meet the requirements on the hardness and strength of the reinforcing layer.
As an alternative embodiment, in the above embodiment, the side edge of the reinforcing layer 130 is flush with the side edge of the tape body 110, so that the difficulty in taking the tape 100 caused by the mutually adhering reinforcing layers 130 can be effectively avoided. If the reinforcing layer 130 is too small relative to the tape body 110, it cannot perform a reinforcing function; if the reinforcing layer 130 is too large relative to the tape body 110, the positioning and taking of the tape 100 during attachment are affected, and the cost of the tape is greatly increased. In this embodiment, the side of the reinforcing layer 130 is flush with the side of the tape body 110, so as to avoid the above problem.
However, according to the present application, it is found that simply adding a release film or the like to the adhesive-free surface of the adhesive tape 100 as the reinforcing layer 130 can increase the strength and hardness of the adhesive tape body 110 to a certain extent, but when the adhesive tape 100 is actually attached, the unreasonable design of the reinforcing layer 130 does not only reduce the difficulty and time of attaching the adhesive tape 100, but also brings additional difficulty to the attaching operation.
For example, if the external dimension of the additional reinforcing layer 130 exceeds the tape body 110, the reinforcing layers 130 exceeding the tape body 110 are easily adhered to each other, so that the user cannot conveniently take the tape 100 for attaching, which increases the difficulty of attaching. For another example, if the additional reinforcing layer 130 is the same as the external dimension of the tape body 110, the additional reinforcing layer 130 cannot be torn off after the attachment, which increases the process and difficulty of the attachment operation. The adhesive tape 100 provided by the embodiment of the application ingeniously utilizes the hardness performance of the enhancement layer 130, the hardness of the enhancement layer 130 is higher than that of the adhesive tape body 100 when the side edge of the enhancement layer 130 is flush with the side edge of the adhesive tape body 110, namely, the enhancement layers 130 are prevented from being bonded together, the difficulty in taking the adhesive tape 100 is avoided, and the enhancement layer 130 of the bent part after the adhesive tape 100 is attached has certain action force for recovering the original shape under the action of the hardness of the enhancement layer 130, so that the adhesive tape body 110 of the bent part is automatically separated from the enhancement layer 130, the additional enhancement layer 130 is conveniently removed from the non-adhesive surface of the adhesive tape body 110, and the difficulty in attachment operation is effectively reduced.
As an alternative embodiment, the tolerance of the first side 131 of the reinforcing layer 130 corresponding to the contact edge 111 is 0.15mm to 0mm with respect to the contact edge. On one hand, because the tolerance of the first side 131 of the reinforcing layer 130 corresponding to the contact edge 111 is a positive tolerance with respect to the contact edge, light leakage caused by an excessively large gap between the contact edge 111 of the adhesive tape body 110 and the polarizer 300 can be avoided, and the yield of products is further improved, on the other hand, because the tolerance of the first side 131 of the reinforcing layer 130 corresponding to the contact edge 111 does not have a negative tolerance with respect to the contact edge, that is, there is no situation that the adhesive-free surface of the contact edge 111 is not covered by the reinforcing layer 130, the hardness and strength of the contact edge 111 can be ensured, and the adhesive tape 100 can be conveniently positioned by using the contact of the contact edge 111 and the polarizer 300.
As described above, the adhesive tape 100 of the present application does not need to increase additional processes and operation time, the attachment operation is simple and convenient, the difficulty of the attachment operation is reduced, the efficiency of the attachment operation and the quality of the attachment of the adhesive tape 100 are improved, the production cost and the product reject ratio are reduced, and the customer complaint of the client side is avoided. In addition, a new idea of optimizing the design scheme of the adhesive tape 100 by a liquid crystal display designer can be effectively opened.
As an alternative embodiment, the reinforcing layer 130 has a rectangular structure, and the reinforcing layer 130 includes a second side edge connected to the first side edge 131, where the length of the second side edge is L ═ m + h +0.5 mm; wherein L is the length of the second side, m is the distance between the side of the polarizer 300 contacting the contact edge 110 and the edge of the liquid crystal display module 200, and h is the thickness of the liquid crystal display module 200. In this embodiment, the length of the second side edge is set to L + h +0.5mm, which facilitates the automatic separation of the reinforcing layer 130 from the tape body 110 during the attachment operation.
As an alternative embodiment, as shown in FIG. 3, the sum T2 of the thicknesses of the reinforcing layer 130 and the tape body 110 is greater than the thickness T1 of the polarizer 300. The sum T2 of the thicknesses of the reinforcing layer 130 and the tape body 110 is greater than the thickness T1 of the polarizer 300, that is, the whole thickness of the tape 100 protrudes out of the polarizer 300 during attachment, so that the tape 100 can be conveniently aligned during attachment, and the tape body 110 can be prevented from being adhered to the upper side of the polarizer 300 during attachment. Further preferably, the thickness of the reinforcing layer 130 is greater than the thickness of the polarizer 300, so that the sum T2 of the thicknesses of the reinforcing layer 130 and the tape body 110 is greater than the thickness T1 of the polarizer 300, that is, when attaching is performed, whether the tape is attached to the upper side of the polarizer 300 and whether a gap or other defects exist between the tape and the polarizer can be determined according to the thickness of the reinforcing layer 130 relative to the polarizer 300, defects caused by attachment can be found in time and corrected in time, and complaints of clients caused by final products are avoided.
Further preferably, the thickness of the reinforcing layer 130 is 50 μm to 150 μm; the thickness of the tape body 110 is 50 μm to 150 μm. The sum T2 of the thicknesses of the reinforcing layer 130 and the tape body 110 is 20-50 μm thicker than the thickness T1 of the polarizer 300. The thickness of the reinforcing layer 130 is also related to the stiffness of the reinforcing layer, and generally the thicker the thickness of the reinforcing layer 130, the greater the stiffness of the reinforcing layer 130. In the present application, the thickness of the reinforcing layer 130 and the hardness of the material thereof can be determined according to the specific requirements of cost and elasticity, so that the reinforcing layer 130 can have a certain resilience after being bent, and can be separated from the adhesive-free surface of the adhesive tape body.
As an alternative embodiment, the peel strength of the non-adhesive surface of the reinforcing layer 130 and the tape body 110 is less than the peel strength of the adhesive surface of the tape body 110 relative to the surface of the liquid crystal display module 200. The reinforcing layer 130 has a lower peel strength relative to the non-adhesive surface of the tape body 110, so that the reinforcing layer 130 can be more conveniently separated from the tape body 110 under the action of the hardness thereof, and further, the adhesive surface of the tape body 110 has a higher peel strength relative to the surface of the liquid crystal display module 200, so that the reinforcing layer 300 can be automatically separated from the non-adhesive surface of the tape body 110 without adverse effect on the attachment of the tape 100.
As an alternative embodiment, the structure of the adhesive surface direction of the adhesive tape body 110 matches the structure of the liquid crystal display module 200. Generally, the area of the liquid crystal display module 200 to which the tape is attached has a flat surface, and the tape body 100 has a flat adhesive surface. However, in some cases, the surface of the liquid crystal display module 200 to which the tape is attached is not flat, for example, the side surface of the liquid crystal display module is often provided with some structures such as raised ribs, bumps, recessed grooves, and recessed points, and the structure of the adhesive surface direction of the tape body 110 is matched with the structures of the liquid crystal display module 200, so that the surface of the tape attached is flat and beautiful. Wherein, sticky tape body 110 includes range upon range of substrate layer and glued membrane layer, and the one side of the substrate layer that the glued membrane layer is located is the gluey face direction of sticky tape body 110, and the one side that the substrate layer kept away from the glued membrane layer is the no gluey face of sticky tape body 110. In this embodiment, the structure of the adhesive surface direction of the adhesive tape body 110 matches with the structure of the liquid crystal display module 200, that is, the structure of the adhesive film layer can also match with the structure of the liquid crystal display module 200, or the structures of the substrate layer and the adhesive film layer can also match with the structure of the liquid crystal display module 200.
