Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display device. BACKGROUND

[0002] With the iterative update of display technology, UTG (ultra-thin glass) is arranged on the display panel of the folding display device as a glass cover plate to improve surface texture, reduce creases and improve mechanical properties. However, the ultra-thin glass of the display panel of the folding display device is prone to burst, which reduces the safety of the folding display device. In order to improve the burst problem of the glass cover plate of the display panel of the folding display device, a conventional scheme arranges a plastic protective layer on the ultra-thin glass of the glass cover plate of the display panel of the folding display device. Although the plastic protective layer can improve the burst problem of the display panel of the folding display device, it also reduces the glass touch of the glass cover plate of the display panel of the folding display device. In order to improve the use touch of the folding display device, the thickness of the ultra-thin glass is increased to improve the glass touch of the glass cover plate. However, the increase of the thickness of the ultra-thin glass also reduces the bending performance of the folding display device. CONTENT OF THE UTILITY MODEL

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0028] In addition, the terms "first", "second", and similar terms do not denote any order, quantity, or importance, but are used to distinguish different technical features. The term "multiple" and similar terms mean two or more, unless otherwise explicitly limited.

[0029] The first embodiment of the present application provides a first display device 10, referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 The display device 10 includes two non-bending display parts AA and a bending display part BB between the two non-bending display parts AA. The display device 10 further includes a display panel 100, a metal mesh support layer 200, and a glass cover plate 300.

[0030] Specifically, the metal mesh support layer 200 is arranged on the backlight side of the display panel 100; the glass cover plate 300 is arranged on the light-emitting side of the display panel 100, and the glass cover plate 300 includes two flat parts 310 and a bending part 320 between the two flat parts 310. The thickness d1 of the flat part 310 is greater than the thickness d3 of the metal mesh support layer 200, and the thickness d2 of the bending part 320 is less than the thickness d3 of the metal mesh support layer 200. In the top view of the display device 10, the flat part 310 overlaps the non-bending display part AA, and the bending part 320 overlaps the bending display part BB.

[0031] The conventional folding display device 10 is provided with a plastic layer protection layer on the ultra-thin glass of the glass cover plate 300 on the display panel 100, wherein the thickness of the ultra-thin glass is 30-50um. Although the plastic protection layer can improve the burst problem of the display panel 100 of the folding display device 10, it also leads to the reduction of the glass touch feeling of the glass cover plate 300 of the display panel 100 of the folding display device 10. In order to improve the use touch feeling of the folding display device 10, the thickness of the ultra-thin glass is increased to improve the glass touch feeling of the glass cover plate 300, but the increase of the thickness of the ultra-thin glass also leads to the reduction of the bending performance of the folding display device 10. Therefore, the technical solution of the present application is to set the glass cover plate 300 to include two flat parts 310 and a bending part 320 between the two flat parts 310. The thickness d1 of the flat part 310 is greater than the thickness d3 of the metal mesh support layer 200, and the thickness d2 of the bending part 320 is less than the thickness d3 of the metal mesh support layer 200. The bending part 320 corresponding to the bending display part BB of the glass cover plate 300 is thinned, so that the bending part 320 of the glass cover plate 300 is more easily bent, thereby ensuring the bending performance of the display device 10. And because the thickness d1 of the flat part 310 is greater than the thickness d3 of the metal mesh support layer 200, compared with the conventional scheme, the thickness d1 of the flat part 310 of the glass cover plate 300 is increased, thereby improving the glass touch feeling of the display device 10.

[0032] In this embodiment, the display device 10 is an inward folding device.

[0033] It should be noted that the inward folding device is a display device 10 that folds inward, that is, the display surface of the folded display device 10 faces inward.

[0034] In this embodiment, the metal mesh support layer 200 includes two first support portions 210 and a second support portion 220 located between the two first support portions 210. In the top view of the display device 10, the first support portion 210 overlaps with the non-bent display portion AA, and the second support portion 220 overlaps with the bent display portion BB. The second support portion 220 is mesh-like.

[0035] In this embodiment, reference Figure 4 , Figure 5 The thickness d1 of the planar portion 310 is 100um to 200um, the thickness d2 of the bent portion 320 is 30um to 50um, and the thickness d3 of the metal mesh support layer 200 is 80um to 150um. By setting the thickness d1 of the planar portion 310 to 100um to 200um, the thickness d2 of the bent portion 320 to 30um to 50um, and the thickness d3 of the metal mesh support layer 200 to 80um to 150um, compared with the conventional ultra-thin glass with a thickness of 30um to 50um, the thickness of the glass cover 300 is increased, thereby improving the glass feel of the display device 10. Furthermore, by reducing the thickness d2 of the bent portion 320 of the glass cover 300, the bent portion 320 of the glass cover 300 is made easier to bend, thereby ensuring the bending performance of the display device 10. Preferably, the thickness d1 of the planar portion 310 is 100um, 110um, 120um, 130um, 140um, 150um, 160um, 170um, 180um, 190um or 200um, the thickness d2 of the bent portion 320 is 30um, 32um, 34um, 36um, 38um, 40um, 42um, 44um, 46um, 48um or 50um, and the thickness d3 of the metal mesh support layer 200 is 80um, 85um, 90um, 95um, 100um, 105um, 110um, 115um, 120um, 125um, 130um, 135um, 140um, 145um or 150um.

[0036] In this embodiment, reference Figure 2The display device 10 further comprises a light shielding ink 400 arranged on a surface of the glass cover plate 300 facing the display panel 100. In the technical solution of the present application, the thickness of the glass cover plate 300 is increased to enhance the impact resistance of the glass cover plate, and the light shielding ink 400 is arranged on a surface of the glass cover plate 300 facing the display panel 100, i.e., the glass cover plate 300 is used outwardly, so as to ensure the impact resistance of the light-emitting side of the display device, and no other film layer except the organic layer 800 needs to be arranged on a side of the glass cover plate 300 away from the display panel 100, and the glass touch of the display device 10 can be further improved.

[0037] In the embodiment, reference is made to Figure 2 The display device 10 further comprises a metal support layer 500 arranged on a side of the metal mesh support layer 200 facing the display panel 100, and a back plate 600 arranged on a side of the metal mesh support layer 200 facing the display panel 100, and the back plate 600 is fixed with the display panel 100, wherein the entire surface of the metal support layer 500 is fixed with the back plate 600. By arranging the display device 10 to further comprise the metal support layer 500 arranged on a side of the metal mesh support layer 200 facing the display panel 100, and the back plate 600 arranged on a side of the metal mesh support layer 200 facing the display panel 100, and the back plate 600 is fixed with the display panel 100, wherein the entire surface of the metal support layer 500 is fixed with the back plate 600, the metal support layer 500 can cooperate with the metal mesh support layer 200 and the back plate 600 to improve the rigidity of the back light side of the display panel 100, thereby improving the impact resistance of the back light side of the display panel 100 of the display device.

[0038] In the embodiment, reference is made to Figure 2 The display device 10 further comprises a protection layer 700 fixed with the display panel 100 and the glass cover plate 300, wherein the thickness d4 of the metal support layer 500 is less than the thickness d5 of the protection layer 700. Since the display device 10 is an inner folding display device 10, when the thickness d4 of the metal support layer 500 is too large, the bending difficulty of the bending display part BB of the display device 10 is increased, and therefore, by arranging the thickness d4 of the metal support layer 500 to be less than the thickness d5 of the protection layer 700, the problem that the display device 10 is difficult to fold due to the too large thickness d4 of the metal support layer 500 can be avoided.

[0039] In the embodiment, the thickness d4 of the metal support layer 500 is 10-20um, and the thickness d5 of the protective layer 700 is 23-50um. By setting the thickness d4 of the metal support layer 500 to be 10-20um and the thickness d5 of the protective layer 700 to be 23-50um, on the one hand, the rigidity of the display panel 100 on the backlight side can be effectively improved without the thickness d4 of the metal support layer 500 being too small, and on the other hand, the problem that the bending part 320 of the glass cover plate 300 is difficult to bend can be avoided when the thickness d4 of the metal support layer 500 is too large. Preferably, the thickness d4 of the metal support layer 500 is 10um, 11um, 12um, 13um, 14um, 15um, 16um, 17um, 18um, 19um or 20um, and the thickness d5 of the protective layer 700 is 23um, 26um, 29um, 32um, 35um, 38um, 41um, 44um, 47um or 50um.

[0047] In the embodiment, the material of the metal mesh support layer 200 includes stainless steel.

[0048] In the embodiment, the material of the metal support layer 500 includes stainless steel and aluminum alloy.

[0049] ​In this embodiment, referring to Figure 4 , Figure 5 , the surface of the side of the glass cover plate 300 away from the display panel 100 is provided with a slot 330, and the display device 10 further comprises an organic layer 800, the organic layer 800 is arranged on the surface of the glass cover plate 300 away from the display panel 100, and part of the organic layer 800 fills the slot 330; in the top view of the display device 10, the slot 330 overlaps the bending display part BB. By arranging the slot 330 on the surface of the side of the glass cover plate 300 away from the display panel 100, and arranging the organic layer 800 on the surface of the glass cover plate 300 away from the display panel 100, and part of the organic layer 800 filling the slot 330, the organic layer 800 can play a role in protecting the glass cover plate 300, thereby improving the safety of the display device 10 after the glass cover plate 300 bursts; and the slot 330 of the glass cover plate 300 is away from the display panel 100 rather than facing the display panel 100, that is, the fifth adhesive layer 1300 bonded with the glass cover plate 300 is directly connected with the surface of the glass cover plate 300 facing the display panel 100 which is not provided with the slot 330, rather than being connected with the surface of the glass cover plate 300 away from the display panel 100 which is provided with the slot 330, which can reduce the risk of separation between the fifth adhesive layer 1300 and the glass cover plate 300.

[0050] In this embodiment, referring to Figure 4 , Figure 5 , the area S1 of the opening of the side of the slot 330 away from the display panel 100 is greater than the area S2 of the opening of the side of the slot 330 close to the display panel 100. By setting the area S1 of the opening of the side of the slot 330 away from the display panel 100 to be greater than the area S2 of the opening of the side of the slot 330 close to the display panel 100, compared with the scheme of setting the slot 330 as a rectangle, the edge visibility of the slot 330 can be reduced, and the visual effect of the display device 10 can be avoided from being reduced.

[0051] In this embodiment, the side wall of the slot 330 is a bevel.

[0052] In this embodiment, referring to Figure 5 , the side wall of the slot 330 is an arc-shaped concave surface, and the center of curvature m of the arc-shaped concave surface and the center n of the slot 330 are located on the same side. By setting the side wall of the slot 330 as an arc-shaped concave surface, and the center of curvature m of the arc-shaped concave surface and the center n of the slot 330 are located on the same side, the contact area between the organic layer 800 and the glass cover plate 300 can be increased, thereby reducing the risk of the organic layer 800 separating from the glass cover plate 300.

[0053] In the embodiment, the side wall of the slot 330 is an arc convex surface, and the curvature center of the arc convex surface and the center of the slot 330 are located on different sides. By setting the side wall of the slot 330 as an arc convex surface, and the curvature center of the arc convex surface and the center of the slot 330 are located on different sides, the contact area between the organic layer 800 and the glass cover plate 300 can be increased, thereby reducing the risk of separation between the organic layer 800 and the glass cover plate 300.

[0054] The second embodiment of the present application provides a second display device 10, referring to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 The display device 10 includes two non-bending display parts AA and a bending display part BB located between the two non-bending display parts AA, and the display device 10 further includes a display panel 100, a metal mesh support layer 200, and a glass cover plate 300; the metal mesh support layer 200 is arranged on the backlight side of the display panel 100; the glass cover plate 300 is arranged on the light-emitting side of the display panel 100, and the glass cover plate 300 includes two planar parts 310 and a bending part 320 located between the two planar parts 310, the thickness d1 of the planar part 310 is greater than the thickness d3 of the metal mesh support layer 200, and the thickness d2 of the bending part 320 is less than the thickness d3 of the metal mesh support layer 200; in the top view of the display device 10, the planar part 310 overlaps with the non-bending display part AA, and the bending part 320 overlaps with the bending display part BB.

[0055] The conventional scheme sets a layer of plastic protective layer on the ultra-thin glass of the glass cover plate 300 of the display panel 100 of the folding display device 10, wherein the thickness of the ultra-thin glass is 30-50 um, although the plastic protective layer can improve the burst problem of the display panel 100 of the folding display device 10, but also leads to the decrease of the glass touch of the glass cover plate 300 of the display panel 100 of the folding display device 10, so as to improve the use touch of the folding display device 10, further increase the thickness of the ultra-thin glass to improve the glass touch of the glass cover plate 300, but the increase of the thickness of the ultra-thin glass also leads to the decrease of the bending performance of the folding display device 10. Therefore, the technical scheme of the present application sets the glass cover plate 300 to include two plane parts 310 and a bending part 320 between the two plane parts 310, the thickness d1 of the plane part 310 is greater than the thickness d3 of the metal mesh support layer 200, and the thickness d2 of the bending part 320 is less than the thickness d3 of the metal mesh support layer 200; the bending part 320 corresponding to the bending display part BB of the glass cover plate 300 is thinned, so that the bending part 320 of the glass cover plate 300 is more easily bent, thereby ensuring the bending performance of the display device 10, and because the thickness d1 of the plane part 310 is greater than the thickness d3 of the metal mesh support layer 200, compared with the conventional scheme, the thickness d1 of the plane part 310 of the glass cover plate 300 is increased, thereby improving the glass touch of the display device 10.

[0056] In the embodiment, the display device 10 is an outer folding folding device.

[0057] It should be noted that the outer folding folding device is a display device 10 folded towards the outside, that is, the display surface of the display device 10 faces outward.

[0058] In the embodiment, the metal mesh support layer 200 includes two first support parts 210 and a second support part 220 between the two first support parts 210, in the top view of the display device 10, the first support part 210 overlaps the non-bending display part AA, and the second support part 220 overlaps the bending display part BB, wherein the second support part 220 is in a mesh shape.

[0059] In the embodiment, the thickness d1 of the flat portion 310 is 300-400 um, the thickness d2 of the bending portion 320 is 40-70 um, and the thickness d3 of the metal mesh support layer 200 is 80-150 um. By setting the thickness d1 of the flat portion 310 to be 300-400 um, the thickness d2 of the bending portion 320 to be 40-70 um, and the thickness d3 of the metal mesh support layer 200 to be 80-150 um, compared with the conventional scheme in which the thickness of the ultra-thin glass is 30-50 um, the thickness of the glass cover plate 300 is increased, thereby improving the glass touch of the display device 10, and since the thickness d2 of the bending portion 320 of the glass cover plate 300 is reduced, the bending portion 320 of the glass cover plate 300 is more easily bent, thereby ensuring the bending performance of the display device 10; at the same time, compared with the inner folding folding device, the outer folding folding device of the embodiment has higher requirements for impact resistance and a larger bending radius, and therefore a thicker glass cover plate 300 is set to ensure the impact resistance of the display device 10 and further improve the glass touch of the display device 10, and even if the thickness d1 of the flat portion 310 is increased, the risk of breakage of the glass cover plate 300 of the display device 10 when bent is not increased. Preferably, the thickness d1 of the flat portion 310 is 300 um, 310 um, 320 um, 330 um, 340 um, 350 um, 360 um, 370 um, 380 um, 390 um, or 400 um, the thickness d2 of the bending portion 320 is 40 um, 42 um, 44 um, 46 um, 48 um, 50 um, 52 um, 54 um, 56 um, 58 um, 60 um, 62 um, 64 um, 66 um, 68 um, or 70 um, and the thickness d3 of the metal mesh support layer 200 is 80 um, 85 um, 90 um, 95 um, 100 um, 105 um, 110 um, 115 um, 120 um, 125 um, 130 um, 135 um, 140 um, 145 um, or 150 um.

Figure 3 In the technical scheme of the present application, since the thickness of the glass cover plate 300 is increased, the impact resistance of the glass cover plate is enhanced, and therefore the light shielding ink 400 is arranged on a surface of the glass cover plate 300 facing the display panel 100, i.e., the glass cover plate 300 is used externally, thereby ensuring the impact resistance of the light-emitting side of the display device, and there is no need to arrange other film layers except the organic layer 800 on a side of the glass cover plate 300 away from the display panel 100, and the glass touch of the display device 10 can be further improved.

[0061] In the embodiment, the display device 10 further comprises a light shielding ink 400, which is arranged on a surface of the glass cover plate 300 facing the display panel 100.Figure 3 The display device 10 further comprises a metal support layer 500 and a back plate 600, the metal support layer 500 is arranged on the side of the metal mesh support layer 200 facing the display panel 100, the back plate 600 is arranged on the side of the metal mesh support layer 200 facing the display panel 100, and the back plate 600 is fixed with the display panel 100, wherein the whole surface of the metal support layer 500 is fixed with the back plate 600.
