[0031] The present utility model provides a display screen capable of preventing the offset of foam adhesive.
[0032] Referring to Figures 1 - 5 , the display screen capable of preventing the offset of foam adhesive provided by the embodiment of the present utility model includes: a back plate 1, one end of the back plate 1 is provided with a glue frame 2, a pasting area 201 is arranged on the end face of the glue frame 2 opposite to the back plate 1. The display screen capable of preventing the offset of foam adhesive further includes: an inner limiting plate 3, the inner limiting plate 3 is arranged on the end face of the glue frame 2 opposite to the back plate 1, the inner limiting plate 3 is located at the inner edge of the pasting area 201, the inner limiting plate 3 is arranged at the connection of two adjacent sides of the glue frame 2, and at the middle of each side of the glue frame 2; convex plates 4, a plurality of convex plates 4 are arranged in the pasting area 201 and connected to the glue frame 2, and the convex plates 4 are arranged along the length and width directions of the glue frame 2; a first foam adhesive 5, the first foam adhesive 5 is pasted in the pasting area 201, a through groove 501 is opened at the position corresponding to the convex plate 4 on the first foam adhesive 5, and the convex plate 4 extends into the through groove 501; a second foam adhesive 6, the second foam adhesive 6 is pasted and arranged on the end face of the first foam adhesive 5 opposite to the glue frame 2.
[0033] In the technical solution of this embodiment, the display screen that can prevent the offset of the foam adhesive is provided with a convex plate 4, and a through groove 501 is opened on the first foam adhesive 5. During installation, the first foam adhesive 5 is pasted in the pasting area 201, and the convex plate 4 is inserted into the through groove 501, which can limit the first foam adhesive 5 and prevent the first foam adhesive 5 from moving along its width direction into the display area. Since the through groove 501 has been opened on the first foam adhesive 5, the integrity of the first foam adhesive 5 at the position where the through groove 501 is opened is damaged, resulting in easy fracture at the position where the through groove 501 is opened on the first foam adhesive 5. Therefore, a second foam adhesive 6 is pasted on the first foam adhesive 5, and the second foam adhesive 6 is pasted at one end of the first foam adhesive 5, and the two form a whole. In this way, the strength of the first foam adhesive 5 at the position where the through groove 501 is opened can be improved, making it not easy to break. By setting the inner limiting plate 3, and by setting the inner limiting plate 3 on the end face of the glue frame 2 opposite to the back plate 1, the inner limiting plate 3 blocks the first foam adhesive 5 and the second foam adhesive 6, further preventing the foam adhesive from moving towards the display area, solving the problem in the prior art that the foam adhesive is relatively easy to fall off under the influence of vibration, resulting in the offset of the foam adhesive into the display area of the display screen.
[0034] Refer to Figure 4 , in an embodiment of the present invention, the height of the inner limiting plate 3 is greater than the thickness of the first foam adhesive 5.
[0035] In the technical solution of this embodiment, the height of the inner limiting plate 3 is greater than the thickness of the first foam adhesive 5, and the top end of the inner limiting plate 3 exceeds the top end of the first foam adhesive 5, and at the same time, it also exceeds the bottom end of the second foam adhesive 6, which can limit the first foam adhesive 5 and the second foam adhesive 6 to prevent them from offsetting into the display area.
[0036] Refer to 2 and Figure 4 , in an embodiment of the present invention, an outer limiting plate 7 is provided on the end face of the glue frame 2 where the inner limiting plate 3 is provided, and the pasting area 201 is located between the inner limiting plate 3 and the outer limiting plate 7.
[0037] In the technical solution of this embodiment, the existence of the outer limiting plate 7 can prevent the first foam adhesive 5 from offsetting to the outside of the glue frame, and at the same time, it can also prevent the second foam adhesive 6 from offsetting to the outside of the glue frame 2.
[0038] Refer to Figure 4 , in an embodiment of the present invention, the through groove 501 is provided at the central position of the first foam adhesive 5 along the width direction.
[0039] In the technical solution of this embodiment, the distances from the through groove 501 to the side of the first foam adhesive 5 are also equal. On the one hand, the widths from the through groove 501 to the first foam adhesive 5 are equal, and the tensile strengths of the first foam adhesive 5 on both sides in the length direction of the through groove 501 are the same. When stretching the first foam adhesive 5, the deformations of the first foam adhesive 5 on both sides of the through groove 501 are equal, and there will be no situation where the deformation of one side is longer than that of the other side, resulting in the deviation of the first foam adhesive 5.
[0040] Refer to Figure 4 , in an embodiment of the present utility model, the height of the convex plate 4 is less than or equal to the thickness of the first foam adhesive 5.
[0041] In the technical solution of this embodiment, when the second foam adhesive 6 is pasted on the first foam adhesive 5, the convex plate 4 will not hold up the second foam adhesive 6 to cause the second foam adhesive 6 to bulge, avoiding affecting the subsequent pasting process of the glass cover plate.
[0042] Refer to Figure 5 , in an embodiment of the present utility model, the length of the through groove 501 is greater than or equal to the length of the convex plate 4, and the width of the through groove 501 is greater than or equal to the width of the convex plate 4.
[0043] In the technical solution of this embodiment, during use, it is more convenient to align the convex plate 4 with the through groove 501, facilitating the insertion of the convex plate 4 into the through groove 501 and making the pasting of the first foam adhesive 5 more convenient.
[0044] Refer to Figure 5 , in an embodiment of the present utility model, the convex plates 4 are evenly distributed on the glue frame 2, and the convex plates 4 and the glue frame 2 are integrally formed.
[0045] In the technical solution of this embodiment, the convex plates 4 are evenly distributed on the glue frame 2, which can well limit the first foam adhesive 5 to prevent it from shifting into the display area. And being integrally formed with the glue frame 2 can improve its strength to a certain extent and prevent the connection with the glue frame 2 from breaking.
[0046] Refer to Figure 1 , in an embodiment of the present utility model, both the first foam adhesive 5 and the second foam adhesive 6 are double-sided acrylic foam adhesives.
[0047] In the technical solution of this embodiment, one end face of the first foam adhesive 5 is pasted on the pasting area 201 by its own viscosity. One end face of the first foam adhesive 5 and the second foam adhesive 6 that are opposite to each other is fixedly pasted through the viscosity of the first foam adhesive 5 and the second foam adhesive 6 itself. The end face of the second foam adhesive 6 that is opposite to the first foam adhesive 5 is pasted with the glass cover plate.
[0048] The technical principle of the present utility model has been described in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present utility model and cannot be construed as limiting the protection scope of the present utility model in any way. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present utility model without creative efforts, and these embodiments will fall within the protection scope of the present utility model.
