[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0029] The utility model embodiment provides a technical solution:
[0030] First, refer to Figure 1-5 The embodiment of the utility model provides a cover plate that is easy to vent, comprising: a cover plate substrate 100, and a first silk screen ink layer 200, a second silk screen ink layer 300 and a third silk screen ink layer 400 sequentially arranged on the back of the cover plate substrate;
[0031] The first silk-screen ink layer 200 is formed by silk-screen printing with a first ink, the second silk-screen ink layer 300 is formed by silk-screen printing with a second ink, and the third silk-screen ink layer 400 is formed by silk-screen printing with a third ink.
[0032] The third silk-screen ink layer 400 includes a plurality of air guide strips 410 , and the third ink is not disposed at the plurality of air guide strips 410 .
[0033] In the utility model, by setting a third silk-screen ink layer and an air guide strip, the third ink is not set at the air guide strip, so that the third silk-screen ink layer has a plurality of hollow concave air guide channels. When the foam double-sided adhesive is subsequently bonded, the air on the bonding surface can be discharged in time to avoid the bulging phenomenon of the foam double-sided adhesive, thereby improving the overall quality of the display module.
[0034] As a preferred improvement of the present invention, the width of the plurality of air guide strips 410 is 1-2 mm. The above arrangement can ensure the best air bubble removal effect.
[0035] As a preferred improvement of the present invention, the gap between two adjacent air guide strips 410 is 5 mm. The above arrangement can prevent the foam at the air guide strip from collapsing on both sides while ensuring the best bubble discharge effect.
[0036] As a preferred improvement of the present invention, the thickness of the third silk-screen ink layer 400 is 0.1 mm. Therefore, the concave depth of the air guide strip will also be 0.1 mm. The above arrangement can ensure the best air bubble removal effect.
[0037] As a preferred improvement of the utility model, the thickness of the first silk screen ink layer 200 and the second silk screen ink layer 300 are both between 5μm and 7μm. The above arrangement can ensure the silk screen effect of the non-display area, and prevent the double-sided adhesive of foam from being observed by the human eye through the first silk screen ink layer, the second silk screen ink layer and the third silk screen ink layer, which is beneficial to the appearance of the cover. Among them, the second silk screen ink layer is a reverse cover ink, and its function is to prevent the light transmission phenomenon caused by setting only the first silk screen ink layer too thin.
[0038] As a preferred improvement of the present invention, refer to Figure 2 , the cover substrate includes a display area 110 and a non-display area 120;
[0039] The first silk-printing ink layer 200 , the second silk-printing ink layer 300 and the third silk-printing ink layer 400 are all disposed in the non-display area 120 .
[0040] As a preferred improvement of the present invention, the cover substrate is a highly transparent tempered glass, so that the display effect of the display module using the cover in the embodiment of the present invention is better.
[0041] As a preferred improvement of the present invention, one or more of an AG film layer, an AR film layer or an AF film layer is coated on the front surface of the cover substrate. The above configuration enables the surface of the cover substrate to have anti-glare, anti-fingerprint or anti-reflection functions, thereby making the cover in the embodiment of the present invention and the display module using the cover in the embodiment of the present invention more integrated and more transparent.
[0042] As a preferred improvement of the utility model, the first ink, the second ink and the third ink are all ordinary ink or antistatic ink or a combination of the two. When antistatic ink is used, static electricity can be discharged in time to avoid accumulation of static charge on the cover plate surface, thereby reducing the problem of dirt adsorption caused by static adsorption.
[0043] In a second aspect, the embodiment of the utility model further provides a display module, including: a display screen, a foam double-sided adhesive, a housing, and a cover plate that is easy to exhaust as described in the embodiment of the utility model;
[0044] The display screen is arranged in the display area of the cover plate which is easy to exhaust;
[0045] The foam double-sided adhesive is arranged in the non-display area of the easy-to-vent cover plate, and is used to adhere the easy-to-vent cover plate attached to the display screen to the housing.
[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
