Technical Field

[0001] The utility model relates to the display field, in particular to a back anti-scratch cover plate and a smart watch. Background Art

[0002] AMOLED has bright display, high contrast and small screen, and is widely used in smart watch projects. Smart watches have more and more comprehensive functions, integrating touch, display, NFC payment and other functions, and integrating a series of functional components in the narrow space of smart watches, so the sealing requirements for smart watches are relatively high. Once water vapor enters the inside of the smart watch, the functional components inside will have a series of problems such as short circuit and corrosion, which will cause the smart watch to be scrapped.

[0003] Since smart watches have high requirements for sealing, the requirements for the fit between the protective cover and the watch case are also high. However, from the beginning of production, the protective cover has to go through a series of actions, including bonding with the AMOLED, assembly and electrical testing, transportation, customer electrical testing, and assembly. During these actions, the light-shielding ink on the back of the protective cover will inevitably come into contact with foreign objects. In serious cases, the light-shielding ink will be scratched by foreign objects, resulting in scratches, etc., which will cause the light-shielding ink to be uneven and reduce the sealing after bonding with the watch case.

[0030] Embodiment 1

[0031] like Figure 1 and 2 As shown, a back side anti-scratch cover plate comprises:

[0032] The cover body 1 includes a display area 101 and a fitting area 102, wherein the fitting area 102 surrounds the display area 101;

[0033] The light-shielding ink 11 is disposed on the back of the cover body 1 and corresponds to the laminating area 102;

[0034] The DLC film 12 is provided on the back side of the light shielding ink 11 .

[0035] The back anti-scratch cover of the utility model is coated with a layer of DLC film 12 on the light-shielding ink 11 by sputtering. In a series of actions such as production of the protective cover, lamination with the mobile phone dial, assembly and electrical testing, transportation, customer electrical testing, and watch assembly, the DLC film 12 can protect the light-shielding ink 11. Since the hardness of the DLC film 12 is greater than that of the light-shielding ink 11, the scratches caused by foreign objects acting on the DLC film 12 are less than those caused by direct action on the light-shielding ink 11, or even no scratches. Therefore, even if the DLC film 12 touches foreign objects, its surface can be guaranteed to be smooth, and the sealing after lamination with the watch case will not be affected.

[0036] Preferably, the distance between the DLC film 12 and the display area 101 is 0.3-0.5 mm, so as to reserve an assembly tolerance between the display area 101 and the watch dial 3 .

[0037] In this embodiment, the cover plate body 1 may be, but is not limited to, a glass cover plate, a plastic cover plate or a sapphire cover plate.

[0038] Embodiment 2

[0039] In this embodiment, the DLC film 12 is formed on the back side of the light-shielding ink 11 by ion sputtering.

[0040] It should be noted that DLC film, also known as diamond-like carbon film, is a type of amorphous carbon film with properties similar to diamond, high hardness, high resistivity, good optical properties, etc., and also has its own unique tribological properties; its main component is carbon atoms, compared with the carbon atoms in diamond, which are sp 3 The carbon atoms in graphite are bonded in the form of sp 2 The carbon atoms in diamond-like carbon are bonded in the form of sp 3 Key and sp 2 It is a metastable form of amorphous carbon and therefore has the excellent properties of both diamond and graphite.

[0041] Among them, carbon is usually used as a target material for preparing DLC ​​films, and ion sputtering technology is used in a vacuum environment. This technology introduces an ion source, such as an argon ion source, under a high vacuum state to bombard the surface of the carbon target with ions, causing carbon atoms or molecules to leave and deposit on the substrate surface, forming a film with a structure and properties similar to diamond. The DLC film prepared by ion sputtering technology has excellent properties such as high hardness, wear resistance, and chemical inertness, and is suitable for coatings, friction pairs and other fields. At the same time, by controlling the ion bombardment parameters and substrate surface treatment, the structure and properties of the film can be regulated to meet the needs of different applications.

[0044] The smart watch of the utility model improves the hardness of the cover body 1 in the bonding area 102 thereof by coating a layer of DLC film 12 on the light-shielding ink 11 of the cover body 1. In a series of actions such as production of the cover body 1, bonding with the mobile phone dial, assembly and electrical testing, transportation and customer electrical testing, and watch assembly, the DLC film 12 is less scratched or even free of scratches by foreign objects. Therefore, even if the DLC film 12 comes into contact with foreign objects, its surface can be kept smooth and will not affect its sealing after bonding with the watch case 2.

[0045] The watch dial 3 includes a display panel 31 , and the display panel 31 is arranged on the back side of the cover body 1 .

[0046] In this embodiment, the display panel 31 is an LCD panel or an OLED panel.
