[0019] 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.

[0020] 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.

[0021] The utility model embodiment provides a technical solution:

[0022] First, reference Figure 1-2 The utility model discloses a foam double-sided adhesive tape that is easy to remove bubbles, comprising: a first double-sided adhesive layer 100, a foam layer 200, and a second double-sided adhesive layer 300 stacked in sequence from top to bottom, wherein the first double-sided adhesive layer 100 comprises a plurality of first double-sided adhesive units 110 arranged at intervals, and the second double-sided adhesive layer 300 comprises a plurality of second double-sided adhesive units 310 arranged at intervals.

[0023] In the utility model, a plurality of first double-sided adhesive units arranged at intervals, and a plurality of second double-sided adhesive units arranged at intervals, are equivalent to hollowing out the first double-sided adhesive and the second double-sided adhesive compared to the traditional foam double-sided adhesive with double-sided adhesive on the entire surface, so that some gas in the bonding surface of the foam double-sided adhesive after bonding can be discharged from the intervals, thereby avoiding the bulging phenomenon of the foam double-sided adhesive and further improving the quality of the display module.

[0024] Preferably, the interval between each pair of first double-sided adhesive units 110 is about 1 mm; the interval between each pair of second double-sided adhesive units 310 is about 1 mm, and the width of the first double-sided adhesive unit 110 and the second double-sided adhesive unit 310 is about 5 mm. This arrangement can prevent the two pairs from sticking to each other due to the gap being too narrow, thereby ensuring the best bubble removal effect, and will not cause collapse due to the spacing being too wide.

[0025] As a preferred improvement of the present invention, a first release film 400 is further disposed above the first double-sided adhesive layer 100 .

[0026] As a preferred improvement of the present invention, a second release film 500 is further disposed below the second double-sided adhesive layer 300 .

[0027] Among them, the bonding force between the first release film and the first double-sided adhesive layer is smaller than the bonding force between the first double-sided adhesive layer and the foam layer; the bonding force between the second release film and the second double-sided adhesive layer is smaller than the bonding force between the second double-sided adhesive layer and the foam layer. The above arrangement can ensure that the first release film and the second release film are easy to remove when the foam double-sided adhesive is in use, and it is not easy to tear off the first double-sided adhesive layer or the second double-sided adhesive layer.

[0028] As a preferred improvement of the present invention, refer to Figure 2 A first film tearing handle 410 is provided on any side of the first release film 400. The above arrangement makes it easy to tear off the first release film 400 by pulling the first film tearing handle 410 when using a foam double-sided adhesive.

[0029] As a preferred improvement of the present invention, refer to Figure 2 A second tearing handle 510 is provided on any side of the second release film 500. The above arrangement makes it easy to tear off the second release film 500 by pulling the second tearing handle 510 when using a foam double-sided adhesive.

[0030] As a preferred improvement of the present invention, refer to Figure 2 The foam layer 200 is a rectangular structure with a hollow middle. This structure allows the foam double-sided adhesive to be closer to the shape of the display screen and to the edge of the display screen, resulting in a better pasting effect.

[0031] As a preferred improvement of the present invention, the plurality of first double-sided adhesive units 110 and the plurality of second double-sided adhesive units 310 are all parallelogram structures. Figure 2 It can be seen that the parallelogram structure of the first double-sided adhesive unit 110 and the second double-sided adhesive unit 310 is equivalent to a traditional whole double-sided adhesive with an inclined surface hollowed out, which ensures the lateral bonding length of a single first double-sided adhesive unit 110 or the second double-sided adhesive unit 310, making the bonding more secure.

[0032] As a preferred improvement of the present invention, the arrangement range of the first double-sided adhesive units 110 and the second double-sided adhesive units 310 does not exceed the range of the foam layer, thereby preventing the first double-sided adhesive units and the second double-sided adhesive units from exceeding the curling edge and affecting the user experience.

[0033] As a preferred improvement of the present invention, the foam layer is made of foamed polyethylene.

[0034] In a second aspect, the embodiment of the utility model further provides a display module, comprising: a display screen, a housing, and a foam double-sided adhesive tape that is easy to remove bubbles as described in the embodiment of the utility model, wherein the foam double-sided adhesive tape is used to bond the display screen and the housing. In particular, for the foam double-sided adhesive tape with a first release film and a second release film, the first release film and the second release film need to be removed before bonding.

[0035] 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.
