[0027] Embodiment 1

[0028] like Figure 1 As shown, a UV-proof AMOLED screen assembly includes a cover plate 1, including a display area and a non-display area;

[0029] AMOLED screen glass 2, the AMOLED screen glass 2 is arranged on the back of the cover plate 1, and the AMOLED screen glass 2 is bonded to the cover plate 1 through OCA glue 5;

[0030] Black foam glue 3, the black foam glue 3 is adhered to the back of the AMOLED screen glass 2, and a plurality of through holes 31 are provided on the surface of the black foam glue 3;

[0031] An anti-UV release film 4 for blocking UV rays is disposed on the back of the black foam adhesive 3 , and the anti-UV release film 4 covers and shields the plurality of through holes 31 .

[0032] The utility model arranges the anti-UV release film 4 on the black foam glue 3 on the back of the AMOLED screen component, which can avoid the display failure problem that the corresponding position of the AMOLED screen component is irradiated by UV light during the production process. The anti-UV release film 4 can effectively block the irradiation of the display screen in the hole area of ​​the UV light, effectively protect the display screen, thereby improving efficiency and low cost, and enhancing the company's competitiveness.

[0033] The anti-UV release film 4 can be formed by doping a UV absorber into a transparent release film or a blue release film, so as to facilitate the subsequent tearing of the UV release film 4 from the black foam glue 3, and then the AMOLED screen glass 2 can be adhered and fixed to other devices through the black foam glue 3.

[0034] Furthermore, the through hole 31 is correspondingly located in the display area of ​​the cover plate 1 .

[0035] Furthermore, a coating 16 is provided on the upper surface of the cover plate 1 .

[0036] The coating 16 may be one of an AG layer (anti-glare layer), an AR layer (anti-reflection and anti-transmittance layer), and an AF layer (anti-fingerprint layer), or a combination of two or more thereof. When used in combination, they may be stacked up and down, or they may be arranged in a frame structure.

[0037] Embodiment 2

[0038] like Figure 2 As shown, as a further optimization scheme of Example 1, in this embodiment, the back side of the cover plate 1 located in the non-visible area is sequentially stacked with a first white ink layer 11, a second white ink layer 12, a third white ink layer 13 and a fourth black reverse cover ink layer 14 from top to bottom, the first white ink layer 11, the second white ink layer 12, the third white ink layer 13 and the fourth black reverse cover ink layer 14 can be formed by silk screen printing, and an ink step difference is formed after the silk screen printing is stacked, and a varnish layer 15 is silk-screened on the back side of the cover plate 1, and the varnish layer 15 can have one or more layers. The varnish layer 15 completely covers the back side of the cover plate 1 located in the visible area, covers the back side of the fourth black reverse cover ink layer 14, and fills the ink step difference. Since a varnish layer 15 is provided on the back of the cover plate 1, and the cost of the varnish layer 15 is much lower than that of OCA optical glue, the overall price of the product is reduced, and the competitiveness of the product is improved. Since the cost of the varnish layer 15 is relatively low, it can be used in large quantities, so that the varnish layer 15 can cover the back of the cover plate 1 located in the visible area, the back of the fourth black reverse cover ink layer 14 and the ink step, that is, the varnish layer 15 can cover the last layer of the fourth black reverse cover ink layer 14, so that the varnish layer 15 is in the outermost layer, and the varnish layer 15 is used as the protection of the last layer of ink. The varnish layer 15 has the characteristics of being more wear-resistant, scratch-resistant, high-temperature resistant and having good heat-sealing performance, and can well prevent the edge ink shedding problem of the cover plate 1 caused by environmental influences, thereby improving the product yield, thereby meeting the company's growing quality requirements.

[0039] In another preferred implementation of the present embodiment, the inner edge of the second white ink layer 12 is located between the inner edge of the first white ink layer 11 and the edge of the cover plate 1. The inner edge of the third white ink layer 13 is located between the inner edge of the second white ink layer 12 and the edge of the cover plate 1; the distance between the inner edge of the second white ink layer 12 and the inner edge of the first white ink layer 11 is 0mm-0.1mm; the distance between the inner edge of the third white ink layer 13 and the inner edge of the second white ink layer 12 is 0mm-0.1mm; the distance between the inner edge of the fourth black reverse cover ink layer 14 and the inner edge of the first white ink layer 11 is 0.2mm-0.4mm; through the formation of the above ink step difference, the three white ink layers can be basically overlapped at one position in the viewing area, so that the thinner part of the white ink is reduced, and the formation of a light-transmitting aperture in the viewing area is avoided.

[0040] Embodiment 3

[0041] like Figure 3 As shown, an antistatic rubber ring 6 is provided on the back of the outer non-display area of ​​the cover plate 1 .

[0042] In this embodiment, the upper surface of the antistatic rubber ring 6 is fixed to the back of the cover plate 1 by gluing, and the back and outer side of the antistatic rubber ring 6 are in contact with the customer's host. By sleeved the antistatic rubber ring 6 on the outer side of the AMOLED screen glass 2, and then gluing the antistatic rubber ring 6 to the back of the cover plate 1 by gluing, the antistatic rubber ring 6 is firmly sleeved on the AMOLED screen glass 2, and the other part of the antistatic rubber ring 6 is 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 electricity requirements of up to 18KV to 20KV.

[0043] 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.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them.
