[0028] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] The utility model provides an AMOLED smart watch that is resistant to external static electricity breakdown, comprising a circular liquid crystal display and a cover plate, wherein the cover plate is arranged above the circular liquid crystal display, an antistatic rubber ring is sleeved on the outer side of the circular liquid crystal display, the lower surface of the cover plate is coated with adhesive glue, and the upper surface of the antistatic rubber ring is fixed to the lower surface of the cover plate by adhesive glue.

[0030] According to the specific situation of the customer's whole machine, since the customer's whole machine anti-static requirements are as high as 18KV to 20KV, it is difficult to meet the requirements of protecting the circular LCD screen by adding components such as TVS tubes from the FPC of the single-machine circular LCD screen. From the perspective of preventing electrostatic damage, one way is to guide static electricity. Starting from the static electricity location and the whole machine, it is currently difficult to achieve the effect required by customers by guiding static electricity. Another way is to block the introduction of static electricity and increase impedance. By setting an anti-static rubber ring on the outside of the circular LCD screen, and then pasting the anti-static rubber ring to the lower surface of the cover plate by gluing, the anti-static rubber ring is firmly set on the circular LCD screen, and the other parts of the anti-static rubber ring are in contact with the customer's host to play a role in blocking static electricity. After testing, it can meet the customer's anti-external static requirements of up to 18KV to 20KV.

[0031] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0032] Example 1

[0033] See also Figure 1, an AMOLED smart watch that prevents external static breakdown provided by the utility model, which includes a circular liquid crystal display screen 1 and a cover plate 2, the cover plate 2 is arranged above the circular liquid crystal display screen 1, and an antistatic rubber ring 3 is sleeved on the outer side of the circular liquid crystal display screen 1, and the lower surface of the cover plate 2 located in the non-visible area and at the outer edge is coated with adhesive glue, and the upper surface of the antistatic rubber ring 3 and the lower surface of the cover plate 2 are fixed by adhesive glue, and the lower surface and outer side of the antistatic rubber ring 3 are in contact with the customer's host. According to the specific situation of the customer's whole machine, since the customer's whole machine antistatic requirement is as high as 18KV to 20KV, it is difficult to meet the requirements of protecting the circular liquid crystal display screen 1 by adding components such as TVS tubes at the FPC of the single circular liquid crystal display screen 1. From the perspective of preventing electrostatic damage, one way is to divert static electricity. Starting from the static electricity position and the whole machine, it is currently difficult to achieve the effect required by customers by diverting static electricity. Another way is to block the introduction of static electricity and increase impedance. By sleeved an antistatic rubber ring 3 on the outside of the circular LCD screen 1, and then gluing the antistatic rubber ring 3 to the lower surface of the cover plate 2, the antistatic rubber ring 3 is firmly sleeved on the circular LCD screen 1, and the other part of the antistatic rubber ring 3 is in contact with the customer's host to block static electricity. After testing, it can meet the customer's anti-external static requirements of up to 18KV to 20KV.

[0034] Furthermore, the outer diameter of the antistatic rubber ring 3 is 45 mm, which corresponds to the outer diameter of the cover plate 2 .

[0035] Furthermore, the inner diameter of the antistatic rubber ring 3 is 41.6 mm, which corresponds to the outer diameter of the circular liquid crystal display screen 1 .

[0036] Furthermore, the thickness of the antistatic rubber ring 3 is 0.2 mm. In other embodiments, the thickness of the antistatic rubber ring 3 can also be selected according to actual needs.

[0037] Example 2

[0038] See also Figure 2As a further optimization scheme of Example 1, in this embodiment, the lower surface of the cover plate 2 located in the non-visible area is sequentially stacked with a first white ink layer 21, a second white ink layer 22, a third white ink layer 23 and a fourth black reverse cover ink layer 24 from top to bottom. The first white ink layer 21, the second white ink layer 22, the third white ink layer 23 and the fourth black reverse cover ink layer 24 can be formed by silk screen printing, and an ink step difference is formed after silk screen printing stacking. The lower surface of the cover plate 2 is silk-screened with a varnish layer 25, and the varnish layer 25 can have one or more layers. The varnish layer 25 completely covers the lower surface of the cover plate 2 located in the visible area, covers the lower surface of the fourth black reverse cover ink layer 24, and fills the ink step difference. Since a varnish layer 25 is provided on the lower surface of the cover plate 2, and the cost of the varnish layer 25 is much lower than that of OCA optical glue, the overall price of the product is reduced, thereby improving the competitiveness of the product. Moreover, since the cost of the varnish layer 25 is relatively low, it can be used in large quantities, so that the varnish layer 25 can cover the lower surface of the cover plate 2 located in the visible area, the lower surface of the fourth black reverse cover ink layer 24, and the ink step difference, that is, the varnish layer 25 can cover the last layer of the fourth black reverse cover ink layer 24, so that the varnish layer 25 is in the outermost layer, and the varnish layer 25 is used as the protection of the last layer of ink. The varnish layer 25 has the characteristics of being more wear-resistant, scratch-resistant, high-temperature-resistant and having good heat-sealing properties, and can well prevent the problem of ink falling off at the edge of the cover plate 2 caused by environmental influences, thereby improving the yield of the product, thereby meeting the company's growing quality requirements.

[0039] Example 3

[0040] See also Figures 2 to 4As a further optimization scheme of Example 1, in this embodiment, the traditional white ink cover plate 2 usually adopts a gradient design when screen-printing multiple layers of white ink, that is, the second white ink layer 22 expands a little more than the first white ink layer 21, and the third white ink layer 23 expands a little more than the second white ink layer 22, so that the height of the ink edge close to the viewing area has a gradual change, that is, the lower layer of ink does not completely cover the upper layer of ink, so that the closer the ink edge to the viewing area is, the thinner it is, and the easier it is for light to penetrate. Although the OCA optical glue or varnish layer 25 can also fill the ink step difference in the viewing area, the closer the white ink is to the viewing area, the thinner it is, and therefore the more transparent it is, thereby forming a light-transmitting aperture in the viewing area, which is not suitable for some high-end display products. In the utility model, two hollow alignment marks 26 are arranged at the corner alignment positions of the first white ink layer 21, and a voiding portion 27 corresponding to the hollow alignment mark 26 is arranged on the second white ink layer 22. The third white ink layer 23 is filled with the hollow alignment mark 26 and the voiding portion 27. According to the hollow alignment mark 26 formed on the first white ink layer 21, the second white ink layer 22 can be screen-printed by the CCD mark grabbing of the automatic screen printing machine. Since the accuracy of the CCD mark grabbing alignment is high, the closer this error value is to zero, the second white ink layer 22 only expands 0mm to 0.1mm more than the first white ink layer 21 in the viewing area. At the same time, the second white ink layer 22 also needs to avoid the two hollow alignment marks 26 of the first white ink layer 21 to facilitate the alignment of the third white ink layer 23. The voiding portion 27 is generally avoided by 0.2mm; then, the CCD mark grabbing of the automatic screen printing machine is used to align the second white ink layer 22. Continue to grab the hollow alignment mark 26 of the first white ink layer 21 and continue to screen-print the third white ink layer 23. Similarly, the third white ink layer 23 only expands 0mm-0.1mm more than the first white ink layer 21 in the viewing area, while the second white ink layer 22 and the third white ink layer 23 remain basically flush. At the same time, the third white ink layer 23 needs to cover the two hollow alignment marks 26 of the first white ink layer 21 and the avoidance part 27 covering the second white ink layer 22 during screen printing. After completing the screen printing of all white ink layers, the fourth black reverse cover ink layer 24 is screen-printed on the periphery of the glass of the jig card cover plate 2. The fourth black reverse cover ink layer 24 expands 0.2mm to 0.4mm more than the first white ink layer 21 in the viewing area. At this time, the three white ink layers basically overlap at one position in the viewing area, so that the thinner part of the white ink is reduced, avoiding the formation of a light-transmitting aperture in the viewing area.
