Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the invention. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and processes are not shown in detail to avoid obscuring the description of the invention with unnecessary detail. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
As shown in fig. 1, the result of testing the top edges of sealant with different widths in the prior art is shown; fig. 2 shows the vertex angle test results of sealant with different widths in the prior art. Referring to fig. 1 and 2, in the sealant structure of the prior art, when the width of the sealant edge is equal to the width of the sealant corner, and if the width of the sealant edge is equal to the width of the sealant corner by 2.0mm, the adhesion force of the sealant vertex angle is 19N (newton), and the adhesion force of the sealant edge is about 67N (newton), which indicates that when the width of the sealant edge is equal to the width of the sealant corner, the adhesion force of the sealant corner is smaller than the adhesion force of the four sides of the sealant. This results in a lower adhesion of the frame in the display panel, which is likely to cause degumming, and thus affects the display effect of the display panel.
In order to solve the above problems, embodiments of the present invention provide a rubber frame structure, a display panel and a display module. The following are detailed below.
The embodiment of the invention provides a frame glue structure which comprises frame glue, wherein the frame glue further comprises a plurality of frame glue edges, and a plurality of frame glue corners formed by combining the plurality of frame glue edges in pairs. At least one frame glue corner in the plurality of frame glue corners has a width larger than that of a frame glue edge corresponding to and adjacent to the at least one frame glue corner.
According to the frame glue structure provided by the embodiment of the invention, the width of the target frame glue corner in the plurality of frame glue corners in the frame glue structure is set to be larger than the width of the frame glue edge adjacent to the target frame glue corner, so that the coating area of the frame glue at the frame glue corner is increased, the adhesive force of the frame glue corner is improved, and the problems of glue failure, degumming and the like are reduced.
specifically, since the frame glue structure in the prior art is easily degummed, which results in poor display of the display panel, the present invention provides a new frame glue structure, as shown in fig. 3, which is a schematic diagram of the frame glue structure provided by the present invention. In this embodiment, the sealant structure provided by the present invention includes the sealant 10, and the sealant 10 further includes a plurality of sealant edges and a plurality of sealant corners formed by combining the plurality of sealant edges.
Specifically, the sealant 10 includes a sealant edge 11, a sealant edge 12, a sealant edge 13, a sealant edge 14, and a first sealant corner 101 formed by combining the sealant edge 11 and the sealant edge 12; the frame glue edge 12 and the frame glue edge 13 are combined to form a second frame glue corner 102; a third frame glue corner 103 formed by combining the frame glue edge 13 and the frame glue edge 14; the sealant edge 14 and the sealant edge 11 are combined to form a fourth sealant corner 104. And the sides of the frame glue and the corners of the frame glue are combined to form a rectangular structure. Meanwhile, the frame adhesive edge 11 and the frame adhesive edge 13 are arranged oppositely, and the frame adhesive edge 12 and the frame adhesive edge 14 are arranged correspondingly.
Based on the above embodiment, the width of the target frame glue corner of the plurality of frame glue corners in the frame glue structure is greater than the width of the frame glue edge adjacent to the target frame glue corner.
Specifically, in an embodiment of the present invention, the width of the frame corner 101 is greater than the width of the frame side 11 or the frame side 12 adjacent to the frame corner 101. Specifically, the width of the frame sealant corner 101 may be greater than the width of the frame sealant edge 11; or the width of the frame glue corner 101 is larger than that of the frame glue edge 12; or the width of the frame sealant corner 101 is greater than the widths of the frame sealant edge 11 and the frame sealant edge 12, and the widths of the frame sealant edge 11 and the frame sealant edge 12 may be equal or different.
On the basis of the above embodiments, the frame sealant corners in the frame sealant structure may be larger than the width of the frame sealant edge adjacent to the target frame sealant corner. Specifically, the widths of the frame sealant corner 101, the frame sealant corner 102, the frame sealant 103 and the frame sealant 104 in the frame sealant 10 are all greater than the widths of two adjacent frame sealant sides.
Based on the above embodiments, the widths of the frame sealant corner 101, the frame sealant corner 102, the frame sealant 103 and the frame sealant 104 in the frame sealant 10 can be equal, and the widths of the frame sealant edge 11, the frame sealant edge 12, the frame sealant edge 13 and the frame sealant edge 14 in the frame sealant 10 are also equal, and the width of the frame sealant corner is greater than the widths of two adjacent frame sealant edges. That is, the frame sealant corners 101, 102, 103 and 104 are greater than the frame sealant edges 11, 12, 13 and 14.
In an embodiment of the present invention, taking a 32-inch frame coating width as an example, the width of the frame sealant edge is usually 1.1mm, and at this time, the width of any one of the frame sealant corners may be greater than 1.1 mm. Specifically, the width of the frame glue corner may be 1.2 mm. At the moment, the coating width of the frame glue corner is increased, so that the coating area of the frame glue corner is increased, the adhesive force of the frame glue corner is increased, the degumming phenomenon of the display panel is reduced, and the display effect of the display panel is enhanced.
Based on the above embodiment, the width of the frame sealant corner is greater than the width of the frame sealant edge, but the width of the frame sealant corner cannot be infinitely greater than the width of the frame sealant edge. The width of the frame glue angle is 1.1mm-1.5 mm. Specifically, the width of the frame adhesive edge may be 1.2mm, 1.3mm, or 1.5 mm.

When the widths of the frame sealant edges are all 0.56mm, the width of any frame sealant corner of the frame sealant corners 101, 102, 103, 104 is set to be larger than the width of the frame sealant edge, i.e. larger than 0.56 mm. At this time, the width of the frame glue corner is set to be larger than that of the frame glue edge, and the width of the frame glue edge is reduced, so that the total frame glue coating amount can be reduced, the cost is reduced, the adhesive force of the frame glue corner is improved, and the problems of glue failure, degumming and the like are reduced.
On the basis of the above embodiments, when the widths of the sides of the sealant are all 0.56mm, the widths of the sealant corners 101, 102, 103, 104 can be set to be greater than the width of the sides of the sealant, i.e., greater than 0.56 mm.

Specifically, the frame rubber corner may be shaped like a crescent moon, which is the shape of the moon at the beginning, and one side of the crescent moon is convex and the other side is concave.
Specifically, in the embodiment of the present invention, the width of a target frame glue corner of the plurality of frame glue corners may be greater than the width of the frame glue adjacent to the target frame glue corner by 0.05-0.3 mm. The frame glue corner embodiment provided by the embodiment of the invention has the advantages that the preparation process is simple, the realization is easy, the coating area of the frame glue corner is increased, the adhesion force of the frame glue corner is increased, and the degumming phenomenon of the display panel is avoided.
