[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model is described clearly and completely, obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0029] This application provides a high-hardness, high-toughness polarizing composite film and a touch display module, which solves the problem of low hardness in existing polarizing composite film structures and improves the performance.

[0030] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0031] Existing polarizing composite films suffer from low hardness and poor practical performance.

[0032] Research has found that, for example Figs. 1-3 As shown, the polarizing composite film structure includes a high-hardness coating, a substrate layer, and a high-hardness coating in sequence. The high-hardness coating is fixed on both sides of the substrate layer by UV curing, which improves the overall hardness of the high-hardness and high-toughness polarizing composite film and enhances the performance of the polarizing composite film.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example:

[0035] like Fig. 1 As shown, a high-hardness and high-toughness polarizing composite film includes a polarizing composite film structure 1, an optical adhesive layer 4, and a polarizer structure 5, wherein the optical adhesive layer 4 is disposed between the polarizing composite film structure 1 and the polarizer structure 5.

[0036] The polarizing composite film structure 1 is bonded to the polarizing film structure 5 by a bonding process.

[0037] The polarizing composite film structure 1 comprises, in sequence, a high-hardness coating 2, a substrate layer 3, and a high-hardness coating 2;

[0038] Each layer of the high-hardness coating 2 is cured on the surface of the substrate layer 3 by a UV curing process.

[0039] The bonding process can be UV adhesive bonding or cold bonding, etc.

[0040] By setting the polarizing composite film structure 1 to include a high-hardness coating 2, a substrate layer 3 and a high-hardness coating 2 in sequence, the high-hardness coating 2 is fixed on both sides of the substrate layer 3 by UV curing, thereby improving the overall hardness of the high-hardness and high-toughness polarizing composite film and enhancing the performance of the polarizing composite film.

[0041] Specifically, the substrate layer 3 is made of polyethylene terephthalate, and the high-hardness coating 2 is made of UV resin.

[0042] Specifically, the thickness of each layer of the high-hardness coating 2 is 5–40 μm;

[0043] The thickness of the substrate layer 3 is 25-250 μm;

[0044] The thickness of the optical glue layer 4 is 1-20 μm.

[0045] Specifically, the high-hard coating layer 2 is prepared by mixing organic resin and nanoparticles, using organic / inorganic hybrid materials, increasing the crosslinking density of the resin, which can improve the hardness of the film, and at the same time, the composite film has high hardness and toughness.

[0046] In the experiment, when curing by UV curing process, it is found that using short-wavelength ultraviolet light can improve the surface curing degree, which is beneficial to improve the contact angle and surface properties, but the internal curing is insufficient, which will cause cracks; using long-wavelength ultraviolet light can improve the internal curing, which is beneficial to improve the crack phenomenon, but the surface curing is insufficient, which will reduce the contact angle properties; the combination of short-wavelength ultraviolet light and long-wavelength ultraviolet light can ensure that the film has high hardness while considering toughness.

[0047] Therefore, when curing by UV curing process, the combination of short-wavelength ultraviolet light and long-wavelength ultraviolet light is used to further improve the composite film to have high hardness while considering toughness.

[0048] As shown in the accompanying drawings, Figs. 2-3 A touch display module, comprising a high-hard high-toughness polarized composite film and a touch display module structure 6.

[0049] One end of the high-hard high-toughness polarized composite film with a polarized film structure 5 is attached to the touch display module structure 6.

[0050] By setting the high-hard high-toughness polarized composite film on the touch display module structure 6, the high-hard high-toughness polarized composite film is used to replace the cover glass 8, OCA glue layer 7 and polarized film structure 5 in the prior art, so as to facilitate the direct use of the touch display module, without adding the cover glass 8, only the high-hard high-toughness polarized composite film is combined with the touch display module structure 6, compared with the existing polarized film, the high-hard high-toughness polarized composite film can produce better effect in the touch display module (TLCM);

[0051] The comparison of the high-hard high-toughness polarized composite film with the existing polarized film and the effect in the application of the touch display module (TLCM) are shown in the following table:

[0052]

[0053]

[0054] Compared with the prior art, the following beneficial effects are achieved:

[0055] 1. By setting the polarizing composite film structure 1 comprising high-hard coating layer 2, substrate layer 3 and high-hard coating layer 2 in turn, the high-hard high-tough polarizing composite film is fixed on both sides of the substrate layer 3 by UV curing, which improves the hardness of the whole high-hard high-tough polarizing composite film and enhances the use effect of the polarizing composite film.

[0056] 2. At the same time, the use of organic / inorganic hybrid materials improves the crosslinking density of the resin, which can improve the hardness of the film, and at the same time, the composite film has high hardness and toughness.

[0057] 3. By setting the high-hard high-tough polarizing composite film on the touch display module structure 6, the high-hard high-tough polarizing composite film replaces the cover glass 8, OCA adhesive layer 7 and polarizing sheet structure 5 in the prior art, so as to facilitate the direct use of the touch display module, without adding the cover glass 8, only the high-hard high-tough polarizing composite film is combined with the touch display module structure 6, compared with the existing polarizing sheet, the high-hard high-tough polarizing composite film can produce better effect in the touch display module (TLCM).
