In order to make the objects, aspects and advantages of the present application more apparent, the present application will be described in further detail with reference to the following examples. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. In addition, the technical features mentioned in the different embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.
The flexible touch sensor is formed by laminating a plurality of layers and has certain deformation capacity. When the flexible touch sensor is applied to some electronic devices with narrow frames, the part of the flexible touch sensor extending outwards beyond the frames needs to be bent to meet the assembly requirements of the narrow frames.
In the bending process of the flexible touch sensor, an internal stress is generated on the portion, extending outwards, of the flexible touch sensor beyond the frame, and when the internal stress is larger than the adhesive force of the optical cement, the layering phenomenon of the bonding layer formed by the frame of the flexible touch sensor and the optical cement is easily caused.
The embodiment of the application provides a manufacturing method of a flexible touch sensor, and the flexible touch sensor obtained by applying the manufacturing method of the embodiment of the application can avoid optical cement delamination in a bending state.
Referring to fig. 1, fig. 1 is a schematic flow chart of a manufacturing method of a flexible touch sensor according to an embodiment of the present disclosure, as shown in fig. 1, the method includes the following steps:
and 11, arranging a protective layer film on the conductive film.
The conductive film is used for forming a touch unit and realizing response to touch operation generated by a user. According to the requirements of actual conditions, the function of the sensor can be realized by arranging a corresponding functional circuit on the base material. The functional circuit disposed on the conductive film has bending resistance and conductivity, and is formed by depositing a conductive material capable of transporting and transmitting current on a substrate, such as tin-doped indium oxide or graphene. The base material of the conductive film can be made of polyvinyl chloride resin, polybutylene terephthalate and other raw materials.
The protective layer film is arranged on the conductive film and used for protecting the conductive film so as to isolate the conductive film from water vapor and prevent the conductive film from being scratched. The protective layer film may be formed from a thermosetting resin and a resin composition. The thermosetting resin may be an epoxy resin, a phenol resin, an amino resin, an unsaturated polyester resin, a polyurethane resin, a thermosetting polyimide resin, or the like, and the resin composition may be a thermoplastic resin.
The protective layer film may be disposed on the conductive film by any suitable means, such as printing, coating, deposition, gluing, and the like. Preferably, the protective layer film may be bonded to the conductive film using an optical adhesive as an adhesive.
And step 12, covering the cover plate on the protective layer film.
The cover plate is a hard structure which is covered on the protective layer film and plays a role in protecting the whole flexible touch sensor. In this embodiment, as the protective layer on the surface of the flexible touch sensor, the cover plate may be a glass fiber reinforced plastic cover plate, a metal cover plate, a plastic cover plate, or the like, and preferably, the glass fiber reinforced plastic cover plate may be made of silicate glass. The rigid glass fiber reinforced plastic cover plate has better corrosion resistance and bearing capacity.
The cover plate may be applied to the conductive film by any suitable means, such as printing, coating, deposition, gluing, etc. Preferably, the cover plate may be bonded to the conductive film using an optical adhesive as an adhesive.
And step 13, forming at least one opening on the protective layer film.
The position of the opening corresponds to the position where the subsequent protective layer film needs to be bent, which is determined by the person skilled in the art according to the relative positions of the protective layer film and the cover plate. The opening can be obtained by punching, laser and the like to open a micro-groove on the protective layer film.
The number of the openings may be any suitable shape, and may be one or more, and preferably, when the number of the openings is 2 or more, in order to avoid that 2 or more of the openings are broken when the protective film is bent, in some embodiments, the distance between adjacent openings needs to be greater than a preset distance. The predetermined distance is an empirical value. It can be determined by a skilled person through a plurality of experiments and the like according to the actual conditions of the sensor (such as the size, the shape of the opening, the number of the openings, the material of the protective film layer and the like).
And 14, bending the conductive film and the protective layer film at the opening along a direction back to the cover plate, and sealing the bent opening.
In the process that the conductive thin film and the protective layer thin film are bent along the direction back to the cover plate, due to the change of material forms, inner side stress can be generated on the conductive thin film and the protective layer thin film at the opening. The protective layer film may be delaminated from the cover plate due to excessive internal stress, and the opening is used to disperse the internal stress of the protective layer film and the conductive film when the protective layer film and the conductive film are bent, so as to reduce the internal stress, and effectively prevent delamination between the cover plate and the protective layer film.
The opening can be obtained by punching, laser and the like to form a micro-groove on the protective layer film.
In some embodiments, the protective layer film and the cover plate are bonded by an optical adhesive to form an adhesive layer, and the opening is used to prevent the cover plate from being delaminated from the adhesive layer.
In addition, since the protective layer film has an opening, the protective effect on the conductive film is lost, and therefore, after the conductive film and the protective layer film are bent, the opening needs to be sealed to protect the conductive film.
According to the manufacturing method of the flexible touch sensor, when the conductive film and the protective layer film are bent along the direction back to the cover plate, the opening is formed in the protective layer film in advance, so that the internal stress of the protective layer film is dispersed when the conductive film is bent, and the delamination between the conductive film and the cover plate can be avoided.
To explain the technical solution of the present application in detail, the present application is further described below with reference to a specific embodiment. Referring to fig. 2, fig. 2 is a flowchart of a method for manufacturing a flexible touch sensor according to another embodiment of the present application, and as shown in fig. 2, the method includes the following steps:
and step 21, arranging a protective layer film on the conductive film.
Referring to fig. 3a, fig. 3a is a schematic diagram illustrating a structure after a protective layer film is disposed on a conductive film. As shown in fig. 3a, the conductive film 31 includes a connection portion 311 and a flexible protrusion 312 extending outward from the connection portion 311.
The conductive film 31 is divided into two parts, namely a connection part 311 and a flexible projection 312, and the flexible projection 312 can be bent along the connection part 311 and the flexible projection 312.
The protective film 32 is disposed on the conductive film 31 and is fixedly connected to the conductive film 31 through a first optical adhesive. The first optical glue may form a first adhesive layer 34 as shown in fig. 3 a.
The protective film 32 covers at least a portion of the connection portion 311 and the flexible protrusion portion 312 to cover the surface of the conductive film 31, so as to prevent the conductive film 31 from being directly exposed in the air and affecting the electrical performance thereof.
Specifically, the portion of the flexible protrusion 312 not covered by the protection film 32 may be a connection terminal for establishing electrical connection with other functional modules.
And step 22, covering the cover plate on the protective layer film.
Referring to fig. 3b, fig. 3b is a schematic view of the cover plate 33 covering the protective film 32. The cover sheet 33 is laminated on the protective film 32, and is fixed to the protective film 32 by a second optical adhesive. The second optical glue may form a second adhesive layer 35 as shown in fig. 3 b.
As shown in fig. 3b, the cover plate 33 is disposed at the uppermost portion of the flexible touch sensor, and plays a role of protecting the entire flexible touch sensor. The connecting part 311 of the conductive film 31 is positioned under the cover plate 33 and protected by the cover plate 33; the flexible protrusion 312 protrudes from the edge 331 of the cover 33 and extends outward, i.e. the edge 331 of the cover 33 is located at the connection point between the connection portion 311 and the flexible protrusion 312.
And step 23, forming at least one opening in the protective layer film along the edge of the cover plate.
Referring to fig. 3c, a plurality of openings 321 are formed in the protective layer film 32 along the edge 331 of the cover plate 33, and fig. 3c shows an enlarged structure of the openings 321 of the protective layer film 32 from another view angle.
And 24, bending the part of the protective layer film covering the flexible convex part and the flexible convex part along the direction back to the cover plate at the opening.
The position of the opening 321 corresponds to the position of the edge 331 of the cover plate 33, a bend is implemented at the opening 321, that is, the flexible protrusion 312 is correspondingly bent, and since the protective layer film 32 partially covers the connection portion 311, another portion of the protective layer film 32 covering the flexible protrusion 312 is bent together with the flexible protrusion 312. Referring to fig. 4, fig. 4 illustrates a structure in which a portion of the protective layer film 32 covering the flexible protrusion 312 and the flexible protrusion 312 are bent in a direction away from the cover plate 33.
For the convenience of understanding of those skilled in the art, the force applied when the protective layer film 32 is bent is illustrated in fig. 4.
As shown in fig. 4, during the process of bending the flexible projection 312 in the direction away from the cover plate 33, the protective film 32 is bonded to the conductive film 31 by the first optical adhesive, and may be partially bent along with the bending of the flexible projection 312. During the bending process of the flexible protrusion 312, the first optical adhesive and the protective layer film 32, due to the change of material form, an inner side stress F shown in fig. 4 may be generated at a position of the protective layer film 32 corresponding to the connection portion 311 and the flexible protrusion 3121。
The second optical adhesive is stressed by the inner side stress F1The tensile force F toward the bending direction of the protective film 32 is generated3When the second optical glue is adhered to the cover plate 33, the adhesive force F2Less than the pulling force F3In this case, the cover sheet 33 may be delaminated from the protective layer film 32 due to insufficient adhesion of the second optical paste.
In the embodiment of the present application, since the passivation film 32 has at least a plurality of openings 321 along the edge 331 of the cover plate 33, the openings 321 enable the inner side stress F1And decreases. Internal stress F1After lowering or reducing, the tensile force F is caused to3Is not easily greater than the adhesive force F provided by the second optical cement2Therefore, the pulling of the second optical cement during bending is slowed down, and the phenomenon of optical cement layering is avoided.
And 25, sealing the bent opening in a dispensing manner.
After the flexible protrusion 311 is bent, the openings 321 may be sealed by dispensing to finally obtain the flexible touch sensor. The glue penetrates into the opening 321, and due to the tension of the glue, the glue is more likely to gather to form a solidified state and is easy to package without overflowing.
The embodiment of the application also provides a flexible touch sensor, which is manufactured by the manufacturing method shown in fig. 1 or fig. 2. Referring back to fig. 4, specifically, the flexible touch sensor includes: a conductive film 31, a protective film 32, and a cover plate 33. The protective layer film 32 is disposed on the conductive film 31, the cover plate 33 is disposed on the protective layer film 32, and the conductive film 31 and the protective layer film 32 are bent in a direction away from the cover plate 33. The bending part of the protective film 32 corresponds to the edge 331 of the cover plate 33, at least one opening 321 is formed at the bending part of the protective film 32, and a sealing part with a suitable size is arranged at the at least one opening 321 to close the at least one opening 321. The sealing portion may be sealed with a sealing material such as an optical cement.
According to the flexible touch sensor provided by the embodiment of the application, before the conductive film 31 and the protective layer film 32 are bent in the direction back to the cover plate 33, the opening 321 is formed in the protective layer film 32 in advance, so that when the conductive film 31 is bent, the internal stress of the protective layer film 32 is dispersed, the conductive film 32 and the cover plate 33 can be prevented from being layered, after the conductive film 32 is bent, the opening 321 is sealed, a sealing part with a corresponding size is formed, and the phenomenon that the opening 321 of the conductive film 32 is exposed in the air to influence the electrical performance of the conductive film is avoided.
In some embodiments, the flexible touch sensor includes a first adhesive layer 34, the first adhesive layer 34 is disposed between the conductive film 31 and the protective film 32, and the first adhesive layer 34 adhesively fixes the conductive film 31 and the protective film 32.
In some embodiments, the flexible touch sensor includes a second adhesive layer 35, the second adhesive layer 35 is disposed between the protective layer film 32 and the cover plate 33, and the second adhesive layer 35 adhesively fixes the protective layer film 32 and the cover plate 33.
In some embodiments, the problem of easy delamination of the flexible touch sensor during bending can be solved by providing a corresponding support structure on the conductive film 31. Thus, the method further comprises: a substrate is placed on the surface of the conductive film 31 away from the protective film 32, and the substrate is connected to the connection portion 311.
Referring to fig. 5, fig. 5 provides a schematic structural diagram of a flexible touch sensor, which is different from the flexible touch sensor in the above embodiments in that the flexible touch sensor further includes a substrate 36.
The substrate base plate 36 is disposed at the bottommost portion of the flexible touch sensor and is used for providing support for the flexible touch sensor. In the present embodiment, the substrate base plate 36 is a hard base plate, which may be made of any suitable type of hard material, such as hard plastic. In order to avoid the substrate 36 affecting the flexible touch sensor, in some embodiments, the substrate 36 may be a transparent substrate meeting a predetermined light transmittance standard.
The connection portion 311 is stacked on the base substrate 36, and is fixedly connected to the base substrate 36.
The connection portion 311 may be fixed to the substrate base 36 by any suitable process or structure. In some embodiments, the connection portion 311 may be fixed to the substrate base 36 by a third optical adhesive, which may form a third adhesive layer 37 shown in fig. 5.
Referring to fig. 5, during the process of bending the flexible protrusion 312 in the direction away from the cover plate 33, the second optical adhesive is subjected to an inner side stress F1Will generate a tensile force F facing the bending direction of the substrate base plate 363When the second optical glue is adhered to the cover plate 33, the adhesive force F2Less than the pulling force F3Meanwhile, the flexible touch sensor may be delaminated from the cover plate 33, the protective layer film 32 and the conductive film 31 due to insufficient adhesion of the second optical adhesive.
Since the bottom layer of the conductive film 31 is provided with the substrate 36, the substrate 36 can generate the stress F with the inner side at the connection part 311 of the conductive film 31 and the flexible protrusion 3121The generated tensile force F3Opposite direction supporting force F shown in FIG. 54. Support force F provided by substrate base plate 364Can offset and reduce materialInternal stress F caused by form change1Thereby reducing the tensile force F to be generated by the second optical cement3. At a tensile force F3After being reduced or reduced, it is less likely to be greater than the adhesion force F provided by the second optical glue2Therefore, the pulling of the second optical cement during bending is slowed down, and the phenomenon of optical cement layering is avoided.
It should be appreciated that the provision of a backing substrate 36 at the very bottom of the flexible touch sensor is a new form of construction, which does not conflict with the above-described reduction of bending losses by providing corresponding openings in the protective film. Therefore, it can be understood by those skilled in the art that the flexible touch sensor provided in the embodiments of the present application is used in combination with the above-mentioned method of providing an opening on the protective layer film of the flexible touch sensor during the manufacturing process and sealing the bent opening, so as to obtain better technical effects. The specific order of execution of the steps is not limited herein.
In addition, in the above preparation steps, the first optical glue, the second optical glue and the third optical glue are respectively used to describe the first adhesive layer 34, the second adhesive layer 35 and the third adhesive layer 37 in fig. 4 and fig. 5, but it should be noted that the "first optical glue", "second optical glue" and "third optical glue" are only used to indicate the positions of the first optical glue, the second optical glue and the third optical glue in fig. 4 and fig. 5. One skilled in the art may select the same optical glue to be used as the first optical glue, the second optical glue, and the third optical glue, or select different optical glues to be used as the first optical glue, the second optical glue, and the third optical glue, respectively.
The optical adhesive is a special adhesive for cementing transparent devices and has certain light transmittance. Which can be determined by the skilled person through experiments and the like according to the needs of the actual situation. In other embodiments, a similar transparent fixing process may be further selected to fixedly connect the structural layers to form the flexible touch sensor.
