This application requires the priority of the Chinese patent application submitted to the China Patent Office on May 18, 2022, with the application number 202210542309.8 and the application name "Touch screen cover and manufacturing method thereof, display screen, and electronic equipment", all of which The contents are incorporated into this application by reference.

Background technique

During the use of the touch screen cover, there is usually a problem of accumulation of static electricity due to friction on the surface of the touch screen cover. When a sufficient amount of static electricity is generated on the surface of the touch screen cover, it will have a serious impact on the electrical characteristics of the thin film transistor (TFT) in the display panel, such as causing TFT threshold voltage drift, high on-state current, and increased leakage. problems, thus triggering market opinions such as splash screens, green screens, and gray spots.

At present, to solve the problem of static electricity accumulation on touch screen covers, the main method is to add an antistatic layer with metal oxide as the coating material in the touch screen cover to reduce the friction voltage on the surface of the touch screen cover, thereby reducing the friction voltage on the surface of the touch screen cover. Realize anti-static protection for display panels. However, since the thickness of the above-mentioned antistatic layer is 3nm to 5nm, the film thickness error generated during the antistatic layer material coating process will have a greater impact on the resistance of the antistatic layer, thereby affecting the resistance stability of the touch screen cover. sex. Specifically, when the thickness of the antistatic layer is too thin due to the film thickness error, the resistance of the antistatic layer is too high, making the resistance of the touch screen cover too high, making it impossible to effectively reduce the friction on the surface of the touch screen cover. Voltage; when the thickness of the antistatic layer is too thick due to the film thickness error, the resistance of the antistatic layer is low, making the resistance of the touch screen cover low, which in turn renders the touch function of the touch screen cover ineffective. Therefore, it is particularly important to reduce the impact of the above-mentioned film thickness error on the resistance stability of the touch screen cover.

Detailed ways

The touch screen cover, display screen and electronic equipment provided by this application are suitable for electronic equipment with display screens such as smartphones, tablet computers, desktop computers, TVs, printers, wearable devices, etc., and can be used in the fields of electronic equipment and automobiles and aerospace fields, etc.

The structure of the touch screen cover, display screen and electronic device provided by this application will be illustrated below with reference to FIGS. 1 to 7 .

Referring to Figure 1, Figure 1 is a schematic structural diagram of a touch screen cover provided by an embodiment of the present application. As shown in FIG. 1 , the touch screen cover 10 includes a base material layer 101 , a first antistatic layer 102 , a first transition layer 103 , a second antistatic layer 104 , a second transition layer 105 and an anti-fingerprint layer 106 .

Among them, the first antistatic layer 102 is located on the first surface (ie, the upper surface) of the base material layer 101 and is used to reduce frictional static electricity generated on the surface of the touch screen cover 10 to reduce friction on the surface of the touch screen cover 10 voltage; the first transition layer 103 is located on the surface of the first antistatic layer 102 away from the base material layer 101 to increase the resistance of the touch screen cover 10 and improve the resistance stability of the second antistatic layer 104 sex. Specifically, the first transition layer 103 is added to the touch screen cover 10 to increase the resistance of the touch screen cover 10 , thereby reducing the impact of film thickness errors on the touch screen due to the antistatic layer material coating process. The resistance value of the cover plate 10 is affected, thereby improving the resistance stability of the touch screen cover plate 10 . In addition, the first transition layer 103 separates the base material layer 101 from the second antistatic layer 104 to prevent impurity ions (such as sodium ions and potassium ions) in the base material layer from affecting the second antistatic layer under high temperature or high humidity environments. The influence of the conductivity of the electrostatic layer 104 thereby improves the resistance stability of the second antistatic layer 104; the second antistatic layer 104 is located on the surface of the first transition layer 103 away from the first antistatic layer 102 to reduce The frictional static electricity generated on the surface of the touch screen cover 10 is used to reduce the friction voltage on the surface of the touch screen cover 10; the second transition layer 105 is located on the surface of the second antistatic layer 104 away from the first transition layer 103. To enhance the adhesion of the anti-fingerprint layer 106; the anti-fingerprint layer 106 is located on the surface of the second transition layer 105 away from the second antistatic layer 104, and is used to improve the contact angle of the touch screen cover 10 to prevent the touch screen cover from Residues of fingerprints on the surface of board 10.

Specifically, the first antistatic layer 102 or the second antistatic layer 104 includes at least one metal oxide. Exemplarily, the first antistatic layer 102 or the second antistatic layer 104 can be any one of indium oxide, tin oxide, aluminum oxide, zinc oxide, or at least two metal oxides among the above four metal oxides. mixture. When the coating material of the first antistatic layer 102 or the second antistatic layer 104 is a metal oxide, the proportion of the metal oxide in the first antistatic layer 102 or the second antistatic layer 104 is usually 100%. . It should be noted that when the coating material of the antistatic layer is metal oxide, the touch screen cover 10 is a glass cover for straight plate machines.

Optionally, the first antistatic layer 102 or the second antistatic layer 104 includes composite conductive polymers (such as polyacetylene, polyphenylene, polyacene, polypyrrole (PPy), polythiophene, polyaniline (PANI) , polyphenylene sulfide, PEDOT:PSS, etc.), cage type sesqui Silicone POSS, silicone or bioactive silicone. Specifically, the first antistatic layer 102 or the second antistatic layer 104 includes at least one of composite conductive polymer, cage silsesquioxane POSS, silicone resin and bioactive silicone. The proportion of the composite conductive polymer, cage silsesquioxane POSS, silicone resin and bioactive silicone in the first antistatic layer 102 or the second antistatic layer 104 is 1% to 30%.

In addition, when the first antistatic layer 102 or the second antistatic layer 104 includes composite conductive polymer, POSS, silicone resin or bioactive silicone, the first antistatic layer 102 or the second antistatic layer 104 also Including polyester material, the polyester material is used to increase the hardness of the first antistatic layer 102 or the second antistatic layer 104, increase the elongation at break and improve the flexibility of the first antistatic layer 102 or the second antistatic layer 104. properties, thereby increasing the hardness of the touch screen cover 10, increasing the elongation at break and improving flexibility of the touch screen cover 10. The sum of the coating surface resistance of the first antistatic layer 102 and the coating surface resistance of the second antistatic layer 104 is between 1E8Ω and 1E12Ω, so that the coating surface resistance of the first antistatic layer 102 is equal to that of the second antistatic layer 104 . The sum of the coating surface resistances of the electrostatic layer 104 can not only meet the touch performance requirements of the touch screen cover 10 but also achieve anti-static protection for the display panel.

It can be understood that the touch screen cover 10 uses at least one of the four types of antistatic materials such as composite conductive polymer, POSS, silicone or bioactive silicone as the coating material of the antistatic layer. Reduce the friction voltage on the surface of the touch screen cover 10 to achieve anti-static protection of the display panel (located below the touch screen cover 10). It can also meet the hardness requirements of both the candy bar machine and the folding machine, making the touch screen cover 10 can be applied to both straight-plate machines and folding machines, with strong applicability. In addition, since the main conductive mechanism of cage silsesquioxane is that the Si-O-Si skeleton in the cage silsesquioxane structure is more conducive to the migration of electrons, and the hydroxyl groups in the cage silsesquioxane structure It can provide more hydrophilicity, thereby enhancing the antistatic properties of cage silsesquioxane; in addition, it can also introduce better conductive properties into the end group materials (such as R groups) of cage silsesquioxane. Optimal materials (such as ammonium groups, sulfonic acid groups, etc.) can be used to improve the conductive properties of cage silsesquioxane. In summary, the conductivity of cage silsesquioxane is determined by its own molecular structure and has a low correlation with the thickness of cage silsesquioxane. The conductivity of metal oxides is mainly determined by the electrons provided by the oxygen vacancies generated by the oxidation reaction of the metal oxide. As the thickness of the metal oxide increases, the number of oxygen atoms increases, and the oxygen vacancies increase accordingly. The electrons provided by the oxygen vacancies increase. As the number of electrons increases, the metal oxide becomes more conductive. Therefore, compared with the solution of using oxide as the coating material of the antistatic layer, when using cage silsesquioxane as the coating material of the antistatic layer, the film thickness of the antistatic layer is related to the thickness of the antistatic layer. The correlation between resistance values is smaller, which can further reduce the impact of film thickness fluctuations during the coating process of the antistatic layer material on the resistance of the touch screen cover 10 , thereby further improving the resistance stability of the touch screen cover 10 sex, and greater applicability.

It should be noted that the coating materials in the first antistatic layer 102 and the second antistatic layer 104 can be the same or different; the proportion of the same material in the first antistatic layer 102 and the second antistatic layer 104 is They may be the same or different, and this application does not limit this. In addition, the thickness of the first antistatic layer 102 and the thickness of the second antistatic layer 104 can be on the nanometer level (eg, 3 to 5 nanometers) or on the micrometer level (eg, 1 to 20 micrometers), which provides high flexibility.

The first transition layer 103 or the second transition layer 105 includes a silicon oxide SiO layer or a silicon oxynitride SiON layer. It can be understood that when the second transition layer 105 includes a SiO layer or a SiON layer, the Si-OH groups provided by the second transition layer 105 can react with the active groups of fluoride in the anti-fingerprint layer 106 to form chemical bonds, thereby improving the resistance to fingerprints. Adhesion of fingerprint layer 106. It should be noted that the coating materials in the first transition layer 103 and the second transition layer 105 may be the same or different, and this application does not limit this.

The base material layer 101 includes, but is not limited to, glass substrate, polyethylene terephthalate (PET), transparent polyimide (Colorless Polyimide, CPI), and thermoplastic polyurethanes (TPU). Or ultra-thin glass (UTG), and other materials used as cover substrates are also suitable for the substrate layer 101 in this application. Wherein, when the touch screen cover 10 is a cover glass (CG) for bar machines, the material of the base material layer 101 is a glass substrate; when the touch screen cover 10 is a flexible cover for folding machines. When the board is used, the material of the base material layer 101 is PET, CPI, TPU or UTG.

In the embodiment of the present application, the touch screen cover 10 adopts a laminated structure of two antistatic layers with a transition layer in the middle. Therefore, the friction voltage on the surface of the touch screen cover 10 can not only be reduced, but also the friction voltage on the surface of the touch screen cover 10 can be reduced. Reduce the impact of the friction voltage on the surface of the touch screen cover 10 on the display panel to achieve antistatic protection of the display panel. You can also increase the resistance of the touch screen cover 10 through the transition layer between the two antistatic layers. , thereby reducing the impact of film thickness errors during the antistatic layer material coating process on the resistance of the touch screen cover 10 , thereby improving the resistance stability of the touch screen cover 10 and having strong applicability.

Furthermore, in addition to adopting a single-layer structure, the first transition layer 103 or the second transition layer 105 in FIG. 1 may also adopt a stacked structure. For details, please refer to the description of the touch screen cover 10 shown in FIG. 2 to FIG. 4 .

Referring to Figure 2, Figure 2 is another structural schematic diagram of a touch screen cover provided by an embodiment of the present application. As shown in FIG. 2 , the first transition layer 103 includes a stacked first transition sub-layer 1031 and a second transition sub-layer 1032 . Wherein, the first transition sub-layer 1031 includes a silicon oxide SiO layer or a silicon nitride SiN layer, the second transition sub-layer 1032 includes a silicon oxide SiO layer or a silicon nitride SiN layer, and the material of the first transition sub-layer 1031 is different from that of the second transition sub-layer 1031 . The materials of sub-layer 1032 are different. Specifically, when the first transition sub-layer 1031 is a SiO layer, the second transition sub-layer 1032 is a SiN layer; when the first transition sub-layer 1031 is a SiN layer, the second transition sub-layer 1032 is a SiO layer.

Referring to Figure 5, Figure 5 is another structural schematic diagram of a touch screen cover provided by an embodiment of the present application. As shown in FIG. 5 , the touch screen cover 10 includes a base material layer 101 and an antistatic layer 107 . The antistatic layer 107 is located on the first surface (ie, the upper surface) of the base material layer 101 and is used to reduce frictional static electricity generated on the surface of the touch screen cover 10 to reduce the frictional voltage on the surface of the touch screen cover 10 . The antistatic layer 107 includes POSS, and a fluorine-containing F group is introduced into at least one R group of POSS, where the F-containing group is used to adjust the contact angle of the surface of the touch screen cover 10 to prevent the surface of the touch screen cover 10 from Residues of fingerprints. In order to facilitate understanding, the following describes the position of introducing F-containing groups in POSS based on the molecular structure of POSS. The molecular structure of POSS is as follows:

It can be seen from the molecular structure of POSS above that POSS has a total of 8 R groups, and an F-containing group can be introduced into at least one of the 8 R groups. The F-containing group here may have an F content of 20% to 100%. When the F content of the F-containing group is 100%, the F-containing group is an all-F group. It should be noted that, in addition to the above-mentioned octahedral cage structure, the POSS provided by this application can also be other polyhedral cage structures (such as ten-sided cage structure, twelve-sided cage structure, etc.), which has high flexibility.

In addition, the thickness of the antistatic layer 107 is 1 micron to 20 microns, which can effectively reduce the film thickness of the antistatic layer 107 material during the coating process compared to an antistatic layer with a thickness of nanometer level (such as 3 to 5 nanometers). The impact of fluctuations on the resistance of the antistatic layer 107 reduces the impact of film thickness fluctuations on the resistance of the touch screen cover 10 during the coating process of the antistatic layer 107 material, thereby improving the resistance stability of the touch screen cover 10 .

The POSS component in the antistatic layer 107 accounts for 1% to 30%. In addition to POSS, the antistatic layer 107 also includes polyester material.

The coating surface resistance of the antistatic layer 107 is between 1E8Ω and 1E12Ω, so that the coating surface resistance of the antistatic layer 107 can not only meet the touch performance requirements of the touch screen cover 10, but also realize the improvement of the display panel.

The correlation between the resistance values is smaller, which can reduce the impact of the film thickness error on the resistance of the touch screen cover 10 during the coating process of the antistatic layer 107 material, thereby improving the resistance stability of the touch screen cover 10 . In addition, the F-containing group introduced into at least one R group of POSS improves the contact angle of the touch screen cover 10 to prevent fingerprints, so that the antistatic layer 107 can not only play an antistatic role, but also It plays the role of anti-fingerprint, thereby replacing the anti-fingerprint layer, thereby effectively simplifying the structure of the touch screen cover 10, which is more conducive to cost saving and greater applicability.
