Description

Technical Field

[0001] The present invention relates to the field of touch control technology, and in particular to a touch control film and a manufacturing method thereof. Background Art

[0002] During the manufacturing process of a single-substrate touch film, if there is a light-shielding part on the substrate, the UV printing will fail because the UV light source cannot penetrate the substrate. For example, the first conductive layer is formed by printing and coating, and then the second conductive layer is formed by printing and coating. However, when printing the second layer, the denser lines of the first conductive layer will block the UV light source, resulting in incomplete curing of the printed glue, resulting in debonding, residual glue, decreased adhesion, etc. For example, in OFS products, black ink needs to be printed first to cover the lead area, which will encounter difficulties in making the conductive layer by UV printing.

[0026] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] First embodiment

[0028] Please refer to Figure 1 The touch film provided in the embodiment of the present invention comprises a substrate 1, a first light shielding layer 2, a second light shielding layer 10, a first UV curing adhesive layer 4, a second UV curing adhesive layer 8, a first conductive layer 5 and a second conductive layer 9. The first light shielding layer 2 directly covers a part of the substrate 1, and the first light shielding layer 2 is a semi-transparent light shielding layer; the first UV curing adhesive layer 4 covers the first light shielding layer 2 and the substrate 1, and the first UV curing adhesive layer 4 is provided with a first conductive layer pattern groove 41; the first conductive layer 5 is embedded in the first conductive layer pattern groove 41; the second UV curing adhesive layer 8 is arranged on the first conductive layer 5, and the second UV curing adhesive layer 8 is provided with a second conductive layer pattern groove 81; the second conductive layer 9 is embedded in the second conductive layer pattern groove 81; the second light shielding layer 10 covers a part of the second UV curing adhesive layer 8, and the second light shielding layer 10 corresponds to the first light shielding layer 2.

[0029] The substrate 1 plays a role of bearing and protection, and the light transmittance of the substrate 1 is relatively high. Specifically, the material of the substrate 1 is PET, PC or flexible glass.

[0030] The first light shielding layer 2 is arranged around the edge of the surface of the substrate 1, and the side of the first light shielding layer 2 is flush with the side of the substrate 1. The thickness of the first light shielding layer 2 is 3 to 20 um. Since the first light shielding layer 2 is translucent, UV light can pass through the first light shielding layer 2 to irradiate the first UV curing adhesive layer 4 and the second UV curing adhesive layer 8, thereby improving the curing effect of the first UV curing adhesive layer 4 and the second UV curing adhesive layer 8 during curing, so that the two are completely cured, thereby improving the firmness between the layers and preventing the occurrence of debonding and residual adhesive.

[0031] In other embodiments, since the edge of the touch film will be cut to a certain extent before use, the first light shielding layer 2 is at a certain distance from the edge of the substrate 1 to facilitate subsequent cutting.

[0032] The first UV curing adhesive layer 4 and the second UV curing adhesive layer 8 are both 5-25um; the first conductive layer pattern groove 41 and the second conductive layer pattern groove 81 are formed by embossing, and their widths are both 1-20um and their depths are both 1-15um.

[0033] The touch film includes a first filling layer 3, a second filling layer 7 and a protective layer 6. Since the pattern grooves are formed by embossing, the bottom thickness of each pattern groove is insufficient or there is a perforation at the bottom, which causes a short circuit between the first conductive layer 5 and the second conductive layer 9. Therefore, the first filling layer 3 and the second filling layer 7 are provided to effectively prevent the occurrence of this phenomenon, and at the same time, the firmness between the layers can be effectively increased, and the bottom of each UV curing layer can be made flat.

[0034] Specifically, the first filling layer 3 is arranged in the frame formed by the first light shielding layer 2, and the upper surface of the first filling layer 3 is flush with the upper surface of the first light shielding layer 2; the protective layer 6 is arranged around the edge of the first UV curing adhesive layer 4, and the second filling layer 7 is arranged in the frame formed by the protective layer 6, and the upper surface of the second filling layer 7 is flush with the upper surface of the protective layer 6. The thickness of the protective layer 6 is 10 to 40 um, and the thickness of the second filling layer 7 is 10 to 40 um.

[0035] In other embodiments, the first leveling layer 3 may also cover the surface of the first light shielding layer 2 and the substrate 1, and the surface of the first leveling layer 3 away from the substrate 1 is flat. Similarly, the second leveling layer 7 may also cover the surface of the protective layer 6 and the first UV curing adhesive layer 4, and the surface of the second leveling layer 7 away from the first UV curing adhesive layer 4 is flat.

[0036] The second light shielding layer 10 is printed with opaque ink on the surface of the second UV curing adhesive layer 8 away from the first conductive layer 5. The position of the first light shielding layer 2 corresponds to the position of the first light shielding layer 2 in the vertical direction, and the two are consistent in size and shape.

[0037] The touch film also includes an anti-glare fingerprint layer, which is arranged on the surface of the substrate 1 away from the first light shielding layer. The anti-glare fingerprint layer can effectively prevent the touch film from being attached to the backlight of the display screen to produce glare, thereby improving the visual effect.

[0038] The present invention also provides a method for manufacturing a touch film, which is used to manufacture the above touch film. The method comprises the following steps.

[0040] S2: preparing a translucent first light-shielding layer 2 on a substrate;

[0047] After step S2 and before step S4, the method further includes preparing a first filling layer 3 in step S3:

[0048] Specifically, a layer of UV curing glue is coated in the frame formed by the first light shielding layer 2, and after curing, a first filling layer 3 is formed. The thickness of the first filling layer 3 is the same as that of the first light shielding layer 2.

[0049] In other embodiments, the first filling layer 3 may also cover the surface of the first light shielding layer 2 and the substrate 1 .

[0050] In step S4, the specific steps of preparing the first UV curable adhesive layer 4 include:

[0051] S41: providing a mold having a first conductive layer pattern groove 41;

[0052] S42: coating a layer of UV curing adhesive on the surface of the first filling layer 3, the UV curing adhesive covering the first filling layer 3 and the first light shielding layer 2;

[0053] S43: Imprinting the mold on the UV curing adhesive to form a first conductive layer pattern groove 41 on the UV curing adhesive;

[0054] S44: The UV curing adhesive is cured to form a first UV curing adhesive layer 4;

[0055] S45: demoulding to obtain a first UV-curable adhesive layer 4 having a first conductive layer 5.

[0056] After step S5, step S6 of preparing a protective layer 6 is also included.

[0057] Specifically, the strippable adhesive is coated on the edges of the first UV curing adhesive layer 4, and the strippable adhesive covers part of the first conductive layer 5, and forms a protective layer 6 after curing, and the protective layer 6 forms a frame surrounding the surface of the first conductive layer.

[0058] After step S6 and before step S8, the method further includes preparing a second filling layer 7, step S7: applying a UV curing adhesive layer within the frame formed by the protective layer 6, and curing to form the second filling layer. The thickness of the second filling layer 7 is the same as that of the protective layer 6.

[0059] In other embodiments, the second filling layer 7 may also cover the surface of the protective layer 6 and the first UV curing adhesive layer 4 .

[0060] In step S8, the specific steps of preparing the second UV curing adhesive layer 8 include:

[0061] S81: providing a mold having a second conductive layer pattern groove 81;

[0062] S82: coating a layer of UV curing adhesive on the surface of the first filling layer 3, wherein the UV curing adhesive covers the first filling layer 3 and the first light shielding layer 2;

At this point, the touch film is manufactured.

[0068] In other embodiments, the step of preparing the anti-glare fingerprint layer may be performed after step S1 and before step S2.

[0069] According to the needs of actual operation, the protective layer 6 can be peeled off by cutting to expose a part of the first conductive layer 5, so as to facilitate the electrical connection between the first conductive layer 5 and the outside. When peeling off the protective layer 6, the part of the second UV curing adhesive layer 8 that is the same size as the protective layer 6 or the part of the second UV curing adhesive layer 8 and the part of the second conductive layer 9 that are covered on the protective layer 6 are also peeled off to expose a part of the first conductive layer 5.

The protective layer corresponds to the first light shielding layer 2 and the second light shielding layer 10 respectively, so the size of the first light shielding layer and the second light shielding layer is equal to the size of the lead area.

[0072] Therefore, the manufacturing method of the touch film provided in this embodiment is substantially the same as the manufacturing method of the touch film mentioned in the first embodiment, and the specific steps that differ therefrom are as follows.

[0075] In the step of preparing the protective layer 6: at least one first conductive layer 5 is preset on the first UV curing adhesive layer 4 to connect with the outside world, and the lead area corresponds to the first light shielding layer 2, and a strippable adhesive is applied to the lead area to form a protective layer 6 after curing.

[0076] In the step of preparing the second filling layer 7: a UV curing adhesive layer is coated on the surface of the first UV curing adhesive layer 4, and the second filling layer 7 is formed after curing; wherein the surface of the second filling layer 7 is flat, and the second filling layer 7 is flush with the protective layer 6 or the second filling layer 7 covers the protective layer 6.
