Description

Technical Field

[0001] The utility model relates to the field of display, and in particular to a protective cover plate with a back side that is scratch-proof 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.

[0032] like Figure 1 and 2As shown, a back-side anti-scratch protective cover plate comprises:

[0033] The cover body 110 includes a display area 111 and a fitting area 112, wherein the fitting area 112 surrounds the display area 111;

[0034] The light-shielding ink 120 is disposed on the back surface of the cover body 110 and corresponds to the laminating area 112;

[0035] The hardening ink 130 is disposed on the back side of the light shielding ink 120 .

[0036] The protective cover of the utility model is coated with a layer of hardened ink 130 on the light-shielding ink 120. In a series of operations 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 hardened ink 130 can protect the light-shielding ink 120. Since the hardness of the hardened ink 130 is greater than that of the light-shielding ink 120, the scratches caused by foreign objects acting on the hardened ink 130 are less than those caused by direct action on the light-shielding ink 120, or even no scratches. Therefore, even if the hardened ink 130 touches foreign objects, its surface can be guaranteed to be smooth, and the sealing after lamination with the watch case will not be affected.

[0037] In this embodiment, the hardening ink 130 may be, but is not limited to, a two-component reactive quick-drying ink based on isocyanate hardener, a urethane resin two-component isocyanate reactive ink, a UV hardening ink, a modified acrylic resin ink, and the like.

[0038] Preferably, the distance between the hardened ink 130 and the display area 111 is 0.3-0.5 mm, so as to reserve an assembly tolerance between the display area 111 and the watch dial.

[0039] In this embodiment, the cover body 110 may be, but is not limited to, a glass cover, a plastic cover or a sapphire cover. Embodiment 2

[0040] like Figure 1 and 3 As shown, a back-side anti-scratch protective cover plate comprises:

[0041] The cover body 110 includes a display area 111 and a fitting area 112, wherein the fitting area 112 surrounds the display area 111;

[0042] The hardened light-shielding ink 140 is disposed on the back surface of the cover body 110 and corresponds to the laminating area 112 .

[0043] The protective cover of the utility model is coated with a layer of hardened shading ink 140 on the bonding area 112 of the cover body 110 to replace the conventional shading ink in the prior art. In a series of operations such as the production of the protective cover, bonding with the mobile phone dial, assembly and electrical testing, transportation and customer electrical testing, and watch assembly, since the hardness of the hardened shading ink 140 is greater than that of conventional shading ink, the scratches caused by foreign objects acting on the hardened shading ink 140 are less than those caused by directly acting on the conventional shading ink, or even no scratches. Therefore, even if the hardened shading ink 140 touches foreign objects, its surface can be guaranteed to be smooth, and its sealing after bonding with the watch case will not be affected.

[0044] The hardened light-shielding ink 140 is obtained by modifying the ink formula on the basis of conventional light-shielding ink. The ink formula is modified in two main aspects: one is to reduce the proportion of carbon compounds in conventional light-shielding ink, and the other is to add ink hardeners; the mass proportion of carbon compounds in the hardened light-shielding ink 140 is between 50% and 60%, and the ink hardener can be but is not limited to isocyanate hardeners, acrylic resins, modified acrylic resins, etc. The mass proportions of different ink hardeners in the hardened light-shielding ink 140 are different, generally between 2% and 5%.

[0045] Preferably, the distance between the hardened ink 130 and the display area 111 is 0.3-0.5 mm, so as to reserve an assembly tolerance between the display area 111 and the watch dial.

[0046] In this embodiment, the cover body 110 may be, but is not limited to, a glass cover, a plastic cover or a sapphire cover. Embodiment 3

[0048] The smart watch of the utility model improves the hardness of the protective cover 100 in the bonding area 112 thereof by coating a layer of hardened ink 130 on the shading ink 120 of the protective cover 100, or directly adopting the hardened shading ink 140 instead of the conventional shading ink. In a series of actions such as production of the protective cover 100, bonding with the mobile phone dial, assembly and electrical testing, transportation and customer electrical testing, and watch assembly, the scratches caused by foreign objects on the hardened ink 130 or the hardened shading ink 140 are few or even no scratches. Therefore, even if the hardened ink 130 or the hardened shading ink 140 touches foreign objects, its surface can be guaranteed to be smooth, and will not affect its sealing after bonding with the watch case 200.

[0049] The watch dial 300 includes a display panel, and the display panel is disposed on the back side of the protection cover 100 .

[0050] In this embodiment, the display panel is an LCD panel or an OLED panel.

[0051] The watch dial 300 further includes a touch function layer, which is disposed between the display panel and the protective cover 100 .

[0052] In this embodiment, the touch functional layer may be, but is not limited to, an OGS functional layer, a GG functional layer, a GF functional layer or a FF functional layer.

[0053] Preferably, the display panel is bonded to the surface of the touch functional layer on the side facing away from the protective cover plate 100 through OCA optical adhesive; if the touch functional layer is an OGS functional layer, the touch functional layer is directly made on the back side of the protective cover plate 100; if the touch functional layer is a GG functional layer, a GF functional layer or an FF functional layer, etc., the touch functional layer is bonded to the back side of the protective cover plate 100 through OCA optical adhesive.
