[0025] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0026] like Figure 1 and Figure 2 As shown, the display screen of the embodiment of the present disclosure includes a housing 1, a liquid crystal screen 2, a double-sided adhesive and a non-adhesive layer 4, the liquid crystal screen 2 includes a main body 21 and a corner part 22, the double-sided adhesive 3 includes a first part 31 and a second part 32, and the main body 21 is bonded to the housing 1 through the first part 31. The second part 32 overlaps the corner part 22, and the non-adhesive layer 4 is bonded to the second part 32. The non-adhesive layer 4 is arranged between the second part 32 and the corner part 22 to separate the second part 32 from the corner part 22, and / or the non-adhesive layer 4 is arranged between the second part 32 and the housing 1 to separate the second part 32 from the housing 1. The double-sided adhesive 3 can be a pull-type adhesive; the non-adhesive layer 4 is a non-adhesive layered structure.

[0027] The display screen of the embodiment of the present disclosure realizes the bonding between the main body 21 of the liquid crystal screen 2 and the housing 1 by the first part 31 of the double-sided adhesive tape 3, thereby realizing the connection between the liquid crystal screen 2 and the housing 1. By setting the non-adhesive layer 4 corresponding to the corner part 22 and bonding it to the second part 32 of the double-sided adhesive tape 3, the second part 32 of the double-sided adhesive tape 3 is separated from the housing 1 by the non-adhesive layer 4, or the second part 32 of the double-sided adhesive tape 3 is separated from the corner part 22 by the non-adhesive layer 4, so as to avoid the corner part 22 of the liquid crystal screen 2 from being bonded to the housing 1. In this way, the corner part 22 of the liquid crystal screen 2 can be prevented from being pulled by the double-sided adhesive tape 3, thereby reducing the risk of the liquid crystal in the corner part 22 being offset, thereby reducing the risk of light leakage problems in the display screen, and improving the user experience.

[0028] In addition, the second portion 32 overlaps the corner portion 22 , so that the second portion 32 supports the corner portion 22 , thereby preventing the liquid crystal screen 2 from being broken.

[0029] In some embodiments, Figure 2 As shown, the housing 1 includes a plate body 11 and a frame 12, the frame 12 is arranged on the side of the plate body 11 facing the liquid crystal screen 2, the plate body 11 and the frame 12 form a receiving cavity 13, and the liquid crystal screen 2 is arranged in the receiving cavity 13. Among them, the first part 31 is bonded to the plate body 11. The double-sided adhesive tape 3 includes an extension part 34, and the extension part 34 is arranged on the side of the second part 32 away from the first part 31. There is a gap between the edge of the liquid crystal screen 2 and the frame 12, and the extension part 34 is arranged between the edge of the liquid crystal screen 2 and the frame 12. Among them, the length of the extension part 34 can be adjusted according to the size of the gap between the edge of the liquid crystal screen 2 and the frame 12.

[0030] By providing the extension part 34 and arranging the extension part 34 between the edge of the liquid crystal screen 2 and the frame 12, when the liquid crystal screen 2 needs to be disassembled, the double-sided adhesive tape 3 can be separated from the housing 1 by pulling the extension part 34, so that the liquid crystal screen 2 can be disassembled from the housing 1. Thus, the disassembly of the liquid crystal screen 2 is facilitated.

[0031] Alternatively, if Figure 1 As shown, the display screen further includes a cover 5, which is annular and connected to the frame 12. The cover 5 blocks the edge of the liquid crystal screen 2 and the interval between the frame 12. The cover 5 and the frame 12 can be bonded.

[0032] For example, Figure 1 and Figure 2 As shown, the opening of the accommodating cavity 13 faces forward, and the cover 5 is arranged on the front side of the housing 1. The cover 5 blocks the edge of the liquid crystal screen 2 and the interval between the frame 12 at the front side. Figure 1 and Figure 2 shown.

[0033] By setting the cover body 5 and utilizing the cover body 5 to block the gap between the edge of the LCD screen 2 and the frame 12, on the one hand, dust can be prevented from entering the accommodating cavity 13 from the gap between the edge of the LCD screen 2 and the frame 12, thereby improving the display effect of the display screen; on the other hand, the extending portion 34 can be blocked, thereby improving the appearance of the display screen.

[0034] Optionally, the length of the second portion 32 is greater than or equal to 10 mm. The length of the second portion 32 can be understood as the size of the second portion 32 in the length direction of the double-sided adhesive tape 3 .

[0035] For example, Figure 2 As shown, the length of the second portion 32 is L1, and L1 is greater than or equal to 10 mm.

[0036] The length of the second portion 32 is greater than or equal to 10 mm, so that at least 10 mm of the corner portion 22 is not pulled by the double-sided tape 3, thereby further reducing the risk of liquid crystal displacement in the corner portion 22 and further reducing the risk of light leakage on the display screen.

[0037] Optionally, the non-adhesive layer 4 is a plastic layer.

[0038] For example, the non-adhesive layer 4 is a PET (Polyethylene terephthalate, polyethylene terephthalate plastic) layer.

[0039] The cost of plastic is relatively low, and by setting the non-adhesive layer 4 as a plastic layer, it is helpful to reduce the cost of the display screen.

[0040] Optionally, the dimension of the non-adhesive layer 4 in the thickness direction of the liquid crystal screen 2 is 0.03 mm to 0.07 mm.

[0041] For example, Figure 1 and Figure 2 As shown, the thickness direction of the liquid crystal screen 2 is consistent with the front-to-back direction, and the dimension of the non-adhesive layer 4 in the front-to-back direction is L2, and L2 is 0.03 mm to 0.07 mm.

[0042] By setting the size of the non-adhesive layer 4 in the thickness direction of the liquid crystal screen 2 to 0.03 mm to 0.07 mm, it is possible to ensure that the non-adhesive layer 4 has good structural strength and avoid damage to the non-adhesive layer 4, and also to avoid the non-adhesive layer 4 being too thick, which results in a high cost of the non-adhesive layer 4. Thus, while ensuring the reliability of the non-adhesive layer 4, it is beneficial to reduce the cost of the display screen.

[0043] Preferably, the dimension of the non-adhesive layer 4 in the thickness direction of the liquid crystal screen 2 is 0.5 mm.

[0044] In some embodiments, Figure 1 and Figure 2 As shown, the housing 1 is provided with a groove 111 with a notch facing the liquid crystal screen 2, and the second part 32 and / or the non-adhesive layer 4 are arranged in the groove 111. The second part 32 and / or the non-adhesive layer 4 are arranged in the groove 111, which can be understood as: one of the second part 32 and the non-adhesive layer 4 is arranged in the groove 111, and the other of the second part 32 and the non-adhesive layer 4 is arranged outside the groove 111; or, both the second part 32 and the non-adhesive layer 4 are arranged in the groove 111.

[0045] For example, Figure 2As shown, the non-adhesive layer 4 includes a first non-adhesive layer 41 and a second non-adhesive layer 42. The first non-adhesive layer 41 is disposed between the second portion 32 and the corner portion 22, and the second non-adhesive layer 42 is disposed between the second portion 32 and the housing 1. The second non-adhesive layer 42 and a portion of the second portion 32 are both disposed in the groove 111.

[0046] It is understandable that after the second part 32 is bonded to the non-adhesive layer 4, the thickness of the second part 32 and the non-adhesive layer 4 is greater than the thickness of the first part 31. At this time, the second part 32 and the non-adhesive layer 4 may interfere with the corner part 22, causing the liquid crystal in the corner part 22 to shift. By providing the groove 111 and arranging the second part 32 and / or the non-adhesive layer 4 in the groove 111, the groove 111 can be used to facilitate the second part 32 and the non-adhesive layer 4 to avoid the second part 32 and the non-adhesive layer 4 from interfering with the corner part 22. In this way, the liquid crystal in the corner part 22 is prevented from shifting, and the risk of light leakage on the display screen is further reduced.

[0047] Optionally, a dimension of the groove 111 in the thickness direction of the liquid crystal screen 2 is less than or equal to 0.2 mm.

[0048] For example, Figure 2 As shown, the dimension of the groove 111 in the front-to-back direction is L3, and L3 is less than or equal to 0.2 mm.

[0049] It is understandable that the provision of the groove 111 on the housing 1 will affect the structural strength of the housing 1. Therefore, the size of the groove 111 cannot be set too large, so as to avoid the structural strength of the housing 1 being too poor and affecting the structural strength of the display screen.

[0050] By setting the size of the groove 111 in the thickness direction of the liquid crystal screen 2 to be less than or equal to 0.2 mm, the influence of the groove 111 on the structural strength of the housing 1 can be reduced, thereby ensuring better structural strength of the housing 1 and thus ensuring better structural strength of the display screen.

[0051] Alternatively, if Figure 2 As shown, the surface of the first non-adhesive layer 41 facing the liquid crystal screen 2 is flush with the surface of the first portion 31 facing the liquid crystal screen 2 .

[0052] For example, Figure 2 As shown, the front surface of the first non-adhesive layer 41 is flush with the front surface of the first portion 31 .

[0053] By setting the surface of the first non-adhesive layer 41 facing the LCD screen 2 and the surface of the first part 31 facing the LCD screen 2 to be flush, the interference between the second part 32 and the non-adhesive layer 4 and the corner part 22 can be effectively avoided, further reducing the risk of light leakage on the display screen.

[0054] like Figure 2 As shown, the first non-adhesive layer 41 includes a first extension segment, the second non-adhesive layer 42 includes a second extension segment, and the extension portion 34 is disposed between the first extension segment and the second extension segment.

[0055] Thus, adhesion between the extension part 34 and the housing 1 as well as between the extension part 34 and the liquid crystal screen 2 is avoided, and it is easy to pull the extension part 34, thereby further facilitating the disassembly of the liquid crystal screen 2.

[0056] Alternatively, if Figure 2 As shown, the double-sided adhesive tape 3 also includes a transition portion 33 , both ends of which are respectively connected to the first portion 31 and the second portion 32 , a portion of the transition portion 33 is disposed in the groove 111 , and the transition portion 33 is bent and spaced apart from the liquid crystal screen 2 .

[0057] By setting the transition part 33 and bending the transition part 33, the transition connection between the first part 31 and the second part 32 is realized by using the transition part 33, so that the stress concentration problem at the connection between the first part 31 and the second part 32 can be avoided, which is beneficial to improving the reliability of the display screen.

[0058] The display screen of the disclosed embodiment adds a non-sticky layer 4 and provides a groove 111 on the shell 1 to prevent the corner portion 22 of the liquid crystal screen 2 from adhering to the shell 1, thereby not only preventing the corner portion 22 of the liquid crystal screen 2 from being pulled by the double-sided tape 3, but also allowing the double-sided tape 3 to support the corner portion 22, thereby preventing the liquid crystal screen 2 from being broken.
