Description

Technical Field

[0001] This utility model relates to the field of glass cover technology, and in particular to a coated cover, a touch screen display, and an electronic device. Background Technology

[0002] With the rapid development of display technology, glass covers, as key components of electronic products, faceplates are facing increasingly higher performance requirements. Traditional glass covers have limitations in terms of high melting point, mechanical strength, thermal stability, electrical performance, and optical performance, making it difficult to meet the needs of current high-performance electronic products. Therefore, developing new coating technologies to form a coating layer with excellent performance on the front side of the glass cover has become a research hotspot in the industry.

[0003] For example, Chinese patent CN 203014915 U discloses a sapphire mobile phone patch, including a patch body, which is a transparent sapphire patch with a thickness of 0.08mm-0.9mm. This invention uses sapphire crystal as the mobile phone screen patch material. Sapphire has high hardness, second only to diamond in nature, with a Mohs hardness of 9. Through a special process, it is processed into a patch with a thickness of 0.08-0.9mm. After being applied to the mobile phone, it solves the problem of easily scratched mobile phone panels currently in use.

[0004] The aforementioned glass cover protection solution simply involves attaching a sapphire film to the surface of a conventional cover to achieve a protective effect. However, this solution not only has certain requirements on the thickness of the sapphire film (too thin and the application process becomes more difficult, too thick and it affects the light transmittance of the cover itself), thus increasing the overall thickness of the cover, but also results in a low degree of integration due to the adhesive method used to bond the sapphire film to the cover, which may affect its subsequent stability. Therefore, a coated cover, touch screen, and electronic device are proposed. Utility Model Content

[0005] Based on this, it is necessary to provide a coated cover plate, a touch screen, and an electronic device to address the above-mentioned technical problems. This involves sequentially coating the surface of a conventional cover plate with a lower coating layer, a middle coating layer, and an upper coating layer, which not only improves hardness and scratch resistance but also allows for a lower overall thickness of the coating layer through the coating design.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A coated cover plate includes a cover glass, on the top of which a coating layer is laid. The coating layer includes a lower coating layer, a middle coating layer, and an upper coating layer, wherein the upper coating layer, the middle coating layer, and the lower coating layer are laid sequentially from top to bottom to form the coating layer, and the lower coating layer is a silicon dioxide layer.

[0008] Furthermore, the middle coating layer is a scandium oxide layer, and the upper coating layer is a ruthenium oxide layer.

[0009] Furthermore, a non-visible area is provided at the edge of the coating layer, and a visible area is provided within the non-visible area.

[0010] Furthermore, the thickness of the silicon dioxide layer is between 100 nanometers and 180 nanometers.

[0011] Furthermore, the thickness of the scandium oxide layer is between fifty nanometers and one hundred nanometers.

[0012] Furthermore, the thickness of the ruthenium oxide layer is 10 nanometers to 30 nanometers.

[0013] A touch display screen includes a coated cover glass and a touch screen disposed at the bottom of the cover glass.

[0014] Furthermore, a display screen is also attached to the bottom of the touch screen;

[0015] The display screen includes an LCD module and a backlight module.

[0016] Furthermore, the LCD module includes an upper polarizer, an upper glass layer, a lower glass layer, and a lower polarizer;

[0017] The upper polarizer, upper glass, lower glass, and lower polarizer are sequentially bonded together from top to bottom to form the LCD module.

[0018] An electronic device includes a touch display screen and a housing for accommodating the touch display screen therein. Side frames extend inward from both sides of the top of the housing, and the side frames enclose a viewing window, which corresponds to a visible area within a coating layer.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The coated cover plate, touch screen and electronic device provided by this utility model adopt a layered coating technology. The upper and lower coating layers, the middle coating layer and the upper coating layer are sequentially coated on the front of the glass cover plate to form a layer film with independent functions. At the same time, because the multiple layer film components are coated sequentially, the adhesion between them and the cover plate is higher and the overall thickness is lower, which ensures good adhesion and long-term stability.

[0021] First, silica is used as the bottom layer, which provides basic mechanical protection and chemical stability to the cover glass due to its hardness, wear resistance, and good chemical stability. Second, scandium oxide is used as the middle layer, which enhances the thermal and chemical stability of the cover glass by utilizing its high melting point and good thermal stability. Finally, ruthenium oxide is used as the top layer, which provides conductivity and specific optical effects (such as anti-reflection and anti-reflection) to the cover glass by utilizing its excellent conductivity and controllable optical properties.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] As described in the background section, conventional cover plate protection solutions simply involve attaching a sapphire film to the surface of a standard cover plate to achieve a protective effect. However, this solution not only has certain requirements on the thickness of the sapphire film (too thin would make the application process more difficult, while too thick would affect the light transmittance of the cover plate itself), thus increasing the overall thickness of the cover plate, but also results in a lower degree of integration between the sapphire film and the cover plate due to the adhesive method, which can easily affect its subsequent stability.

[0037] To solve this technical problem, this utility model provides a coated cover plate, a touch screen display, and an electronic device, which are applied to glass cover plates.

[0038] For details, please refer to Figures 1-6 As shown, the coated cover plate, touch screen and electronic device include a cover glass 1, on which a coating layer 2 is laid. The coating layer 2 includes a lower coating layer 21, a middle coating layer 22 and an upper coating layer 23. The coating layer 23 is formed by the coating layer 22 and the lower coating layer 21 being laid from top to bottom. The lower coating layer 21 is a silicon dioxide layer.

[0039] The coated cover plate, touch screen and electronic device provided by this utility model adopts a layered coating technology. The upper and lower coating layers 21, the middle coating layer 22 and the upper coating layer 23 are sequentially coated on the front side of the cover glass 1 to form layers with independent functions. At the same time, because the multiple layer components are coated sequentially, the adhesion between them and the cover glass 1 is higher and the overall thickness is lower, ensuring good adhesion and long-term stability.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0043] Please refer to Figures 1-6 As shown, a coated cover plate includes a cover glass 1, on which a coating layer 2 is laid. The coating layer 2 includes a lower coating layer 21, a middle coating layer 22, and an upper coating layer 23. The upper coating layer 23, wherein the middle coating layer 22 and the lower coating layer 21 are laid sequentially from top to bottom to form the coating layer 2. The lower coating layer 21 is a silicon dioxide layer (SiO2), and the thickness of the silicon dioxide layer in the lower coating layer 21 is between 100 nanometers and 180 nanometers.

[0044] By applying a lower coating layer 21 to the surface of the cover glass 1, basic mechanical protection and chemical stability are achieved for the cover glass with silicon dioxide as the bottom layer (lower coating layer 21) due to its hardness, fragility, and insolubility. Since the three-dimensional network structure of silicon dioxide is composed of silicon-oxygen tetrahedra, it has high hardness and wear resistance. At the same time, compared with the conventional operation of adding sapphire patches to the cover glass, the silicon dioxide coating layer in this embodiment reduces the overall required thickness and improves the adhesion strength between the silicon dioxide coating layer and the cover glass 1.

[0045] As a further optimization of this embodiment: such as Figure 2 As shown, the intermediate coating layer 22 is a scandium oxide layer (Sc2O3), and the thickness of the scandium oxide layer is between 50 nanometers and 100 nanometers. In this embodiment, the scandium oxide layer is used as the intermediate layer (intermediate coating layer 22), which can enhance the thermal stability and chemical stability of the cover glass 1, because the high melting point and stability of scandium oxide enable it to maintain its performance in high temperature and harsh environment.

[0046] As a further optimization of this embodiment: such as Figure 3 As shown, the upper coating layer 23 is a ruthenium oxide layer (RuO2), and the thickness of the ruthenium oxide layer is 10 nanometers to 30 nanometers. As the top layer (upper coating layer 23), the ruthenium oxide layer provides excellent conductivity and optical properties. The conductivity of ruthenium oxide makes it an ideal choice for applications such as touch screens that require conductive functions.

[0047] The above-mentioned technical means for multi-layer coating in coating layer 2 is a mature and complete existing technology, therefore it is not further described in this embodiment;

[0048] The edge of the coating layer 2 is provided with a non-visible area 25, and a visible area 24 is provided within the non-visible area 25.

[0049] This utility model also proposes a touch screen, including the coated cover plate in Embodiment 1, the coated cover plate referring to the specific structure in Embodiment 1 above, and also including a touch screen 3, the touch screen 3 being disposed at the bottom of the cover glass 1;

[0050] The bottom of the touch screen 3 is also fitted with a display screen 4;

[0051] The display screen includes an LCD module 41 and a backlight module 42.

[0052] The LCD module 41 includes an upper polarizer 410, an upper glass 411, a lower glass 412, and a lower polarizer 413, wherein the upper polarizer 410, the upper glass 411, the lower glass 412, and the lower polarizer 413 are sequentially bonded together from top to bottom to form the LCD module 41.

[0053] Since the touch display screen in this embodiment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0054] This utility model also proposes an electronic device, including a touch screen display as described in Embodiment 2. The specific structure of the touch screen display is the same as that described in Embodiments 1 and 2. It also includes a housing 5, which is used to accommodate the installation of the touch screen display therein. The housing 5 has side frames 51 extending inward from both sides of the top of the housing 5. The side frames 51 enclose a viewing window 52, ​​which is correspondingly arranged with the viewing area 24 in the coating layer 2.

[0055] Since the viewing window 52 corresponds to the visible area 24 in the coating layer 2, the side frame 51 can block the non-visible area 25 of the coating layer 2 and form a rim, so that it can simultaneously form protection for the edge of the cover glass 1, avoiding bumps at the corner edge that could easily affect the tightness of the coating between multiple layers in the coating layer 2.

[0056] Since the electronic device in this embodiment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0057] The usage process of the coated cover plate, touch screen, and electronic device provided by this utility model is as follows: First, a lower coating layer (silicon dioxide) 21 is coated on the surface of the conventional cover glass 1. Then, after the lower coating layer 21 is coated, a middle coating layer (scandium oxide) 22 is coated on its surface. Finally, after the middle coating layer 22 is coated, an upper coating layer (ruthenium oxide) 23 is coated on its surface. By precisely controlling the thickness and composition of each layer, the cover glass 1 achieves excellent performance, as well as good adhesion and long-term stability between the coating layer 2 and the cover glass 1, ensuring its reliability and durability in practical applications.
