Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0018] Please see Figure 1 and Figure 2 This application provides a display device 100, which includes a display panel 1. The display panel 1 can be any one of a liquid crystal display panel, an organic light-emitting diode display panel, a micro-light-emitting diode (Micro-LED) display panel, a sub-millimeter light-emitting diode (Mini-LED) display panel, and a quantum dot display panel. The following description uses an organic light-emitting diode display panel as an example, but it is not limited to this.

[0019] In some embodiments, the display panel 1 may include an array substrate (not shown in the figure), which includes a substrate and a driving circuit layer stacked sequentially. The substrate may include at least one of a glass substrate and a flexible substrate. The driving circuit layer includes a driving circuit. When the display panel 1 is any one of an organic light-emitting diode display panel, a micro-light-emitting diode (Mirco-LED) display panel, a sub-millimeter light-emitting diode (Mini-LED) display panel, and a quantum dot display panel, the array substrate further includes a light-emitting device layer, which is located on the driving circuit layer and includes a light-emitting device. The light-emitting device is connected to the driving circuit to drive the light-emitting device to emit light. When the display panel 1 is a liquid crystal display panel, the array substrate further includes a pixel electrode, which is connected to the driving circuit.

[0020] In some embodiments, when the display panel 1 includes a light-emitting device layer, the display panel 1 may further include an encapsulation layer located on the light-emitting device layer to encapsulate and protect the light-emitting device layer. The encapsulation layer may include either a thin-film encapsulation layer or an encapsulation cover plate 2.

[0021] In some embodiments, the display panel 1 may further include a touch layer (not shown in the figure), which may be integrated onto the display panel 1 or externally attached to the display panel 1 via an adhesive layer or the like.

[0022] like Figure 1 and Figure 2 As shown, the display panel 1 includes a light-emitting surface and a back surface disposed opposite to each other. The back surface can be the surface of the array substrate facing away from the driving circuit layer. The light-emitting surface can be the surface of the uppermost functional layer above the substrate, away from the substrate.

[0023] In some embodiments, please refer to Figure 1 and Figure 2 The display device 100 may further include a cover plate 2, which is located on the side of the light-emitting surface 11 of the display panel 1 opposite to the back surface 12. The cover plate 2 protects the display panel 1 and the like below it. The cover plate 2 may include at least one of a glass cover plate and an organic light-transmitting cover plate. The cover plate 2 can be fixed to the light-emitting surface of the display panel 1 by an adhesive layer.

[0024] In some embodiments, please refer to Figure 1 and Figure 2 The display device 100 may also include a circular polarizer 3, which may be located on the light-emitting side of the display panel 1 to reduce the reflection of ambient light by the display components. In one example, the circular polarizer 3 is located on the side of the cover plate 2 opposite to the display panel 1.

[0025] In some embodiments, please refer to Figure 1 and Figure 2The display device 100 may further include a housing structure 4. The housing structure 4 is provided with a receiving cavity 41 and an opening 42, with the opening 42 communicating with the receiving cavity 41. The opening 42 is located above the receiving cavity 41, and the bottom wall 45 of the housing structure 4 is located below the receiving cavity 41. The display panel 1, the cover plate 2, and the circular polarizer 3 are all located in the receiving cavity 41, with the light-emitting surface 11 of the display panel 1 facing the opening 42, so that the light emitted from the light-emitting surface 11 of the display panel 1 can be emitted to the outside through the opening 42.

[0026] In some embodiments, please refer to Figure 1 and Figure 2 The housing structure 4 may include a first housing 43 and a second housing 44. The first housing 43 is provided with a receiving cavity 41. The second housing 44 is fixed to the first housing 43 and is provided with an opening 42. The second housing 44 is frame-shaped, with the opening 42 in the middle of the frame.

[0027] In some embodiments, please refer to Figure 1 and Figure 2 The display device 100 may further include a support structure 5, which supports and protects the display panel 1. The support structure 5 is also located in the accommodating cavity 41. The support structure 5 is located on the side of the back surface 12 away from the light-emitting surface 11, and on the side of the display panel 1 away from the opening 42. A gap S1 exists between the support structure 5 and the bottom wall 45 of the housing structure 4 below the accommodating cavity 41, reducing the risk of collision between the support structure 5 and the bottom wall 45 of the housing structure 4, thereby damaging the support structure 5.

[0028] In some embodiments, please refer to Figure 1 and Figure 2 The support structure 5 may include one or more metal layers 51. Since the metal layers 51 have a certain strength, they can provide support for the display panel 1. The metal layers 51 may include at least one of a rigid metal layer and a thermally conductive metal layer. The rigid metal layer may include, but is not limited to, steel sheets, giving it sufficient strength and hardness. The thermally conductive metal layer may include at least one of an aluminum layer and a copper layer. While providing support for the display panel 1, the thermal conductivity of the thermally conductive metal layer reduces the risk of heat dissipation to the display panel 1 and affecting the display.

[0029] In some embodiments, please refer to Figure 1 and Figure 2The support structure 5 may further include a buffer layer 52, which provides support and cushioning for the display panel 1. The buffer layer 52 may be located between a metal layer 51 and the display panel 1. The buffer layer 52 may include at least one of foam and organic elastic materials such as rubber. In some embodiments, the buffer layer 52 may also be located on the side of the metal layer 51 facing away from the display panel 1. In one example, the buffer layer 52 may include rigid foam, so that the buffer layer 52 provides both support and cushioning properties.

[0030] In some embodiments, when the substrate of the display panel 1 is a flexible substrate, the support structure 5 may further include a back plate, which is located between the metal layer 51 or the buffer layer 52 and the display panel 1. The back plate may include organic materials, including but not limited to polyethylene terephthalate.

[0031] In one example, see Figure 1 and Figure 2 The support structure 5 may include a metal layer 51 and a buffer layer 52. The metal layer 51 includes an aluminum layer 511, and the buffer layer 52 includes a foam layer 521. The foam layer 521 is fixed to the back of the display panel 1. In this case, the aluminum layer 511 and the foam layer 521 constitute a support structure 5 with heat dissipation and support functions.

[0032] It should be noted that the support structure 5 may include only one of the rigid metal layer, the thermally conductive metal layer and the buffer layer 52, or the support structure may include the rigid metal layer, the thermally conductive metal layer and the buffer layer 52.

[0033] The support structure 5 includes a first surface 531 and a second surface 532 disposed opposite to each other, with the second surface 532 located on the side of the first surface 531 facing away from the back surface 12. Along the stacking direction of the support structure 5 and the display panel 1, the first surface 531 is the surface of the entire support structure 5 closest to the display panel 1, and the second surface 532 is the surface of the entire support structure 5 farthest from the display panel 1. When the support structure 5 is a single film layer, the first surface 531 and the second surface 532 can be two oppositely disposed surfaces of the same film layer along the stacking direction of the display panel 1 and the support structure 5. When the support structure 5 consists of two or more film layers, the first surface 531 and the second surface 532 can be surfaces of two different film layers. For example, when the support structure 5 includes a metal layer 51 and a buffer layer 52, the first surface 531 is the surface of the buffer layer 52 facing away from the metal layer 51, and the second surface 532 is the surface of the metal layer 51 facing away from the buffer layer 52.

[0034] The support structure 5 also includes multiple sides 533, one side 533 connecting the first side 531 and the second side 532. Two sides 533 are the two sides 533 of the support structure 5 along the first direction X of the display device 100, and the other two sides 533 are the two sides 533 of the support structure 5 along the second direction Y of the display device 100. The first direction X and the second direction Y intersect and are both parallel to the back surface. In one example, the first direction X can be the direction of the length of the display device 100, and the second direction Y can be the direction of the width of the display device 100, where the length of the display device 100 is greater than the width of the display device 100.

[0035] In some embodiments, please refer to Figure 1 and Figure 2 The support structure 5 is provided with one or more grooves 54, which are recessed from the second surface 532 toward the first surface 531, i.e., grooves 54 are provided at the bottom of the support structure 5. The display device 100 also includes one or more buffers 6, with one buffer 6 located in a corresponding groove 54. In this way, when the display device 100 is subjected to an external impact force, the buffer 6 in the groove 54 can release the stress generated by the impact force through deformation, thereby improving the impact resistance of the display device 100. In other words, the impact resistance of the display device 100 is improved by utilizing the cooperation between the groove 54 and the buffer 6. Furthermore, the buffer 6 being located in the groove 54 is beneficial because it does not cause an increase in the overall thickness of the display device 100. This is beneficial because it reduces the warpage of the module composed of the display panel 1 and the support structure 5 by increasing the thickness of the support structure 5 without increasing the thickness of the display device 100, thereby improving the module's compression resistance.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 One buffer 6 may be located in a recess 54. In other embodiments, multiple buffers 6 may be located at intervals in a recess 54.

[0037] In some embodiments, at least one buffer 6 has a gap S2 between it and the groove wall of a corresponding groove 54. This gap provides deformation space for the buffer 6, improving the impact resistance of the display assembly.

[0038] In some embodiments, please refer to Figure 1At least one groove 54 has a groove wall comprising a first arcuate surface 541; and / or at least one buffer 6 comprises a second arcuate surface 61. Because the first arcuate surface 541 can better disperse stress generated by external impact, the risk of at least one groove 54 undergoing permanent deformation under external impact is reduced. Similarly, because the second arcuate surface 61 can better disperse stress generated by external impact, the risk of at least one buffer 6 undergoing permanent deformation and losing its buffering performance under external impact is reduced. Furthermore, when the display assembly is subjected to external force, when the buffer 6 comprises the second arcuate surface 61 and the corresponding groove 54 comprises the first arcuate surface 541, the fit between the first arcuate surface 541 and the second arcuate surface 61 can be better.

[0039] In some embodiments, please refer to Figure 1 The first arc-shaped surface 541 surrounds the second arc-shaped surface 61, and there is a gap between the first arc-shaped surface 541 and the second arc-shaped surface 61.

[0040] In some embodiments, either the first arcuate surface 541 or the second arcuate surface 61 may include at least one of a partially circular arcuate surface and a partially elliptical arcuate surface. In one example, both the first arcuate surface 541 and the second arcuate surface 61 include partially elliptical surfaces.

[0041] In some embodiments, please refer to Figure 2 At least one groove 54 may have a groove wall comprising a groove bottom surface 544 and a plurality of groove side surfaces 545 connected to the groove bottom surface 544. Both the groove bottom surface 544 and the plurality of groove side surfaces 545 may be planar. This simplifies the formation of the groove 54. In some embodiments, when both the groove bottom surface 544 and the plurality of groove side surfaces 545 are planar, the included angle between the groove bottom surface 544 and the groove side surfaces 545 may be an obtuse angle. In other embodiments, when both the groove bottom surface 544 and the plurality of groove side surfaces 545 are planar, the included angle between the groove bottom surface 544 and the groove side surfaces 545 may be a right angle or an acute angle.

[0042] In some embodiments, the groove wall of at least one groove 54 may include a groove bottom surface 544 and a plurality of groove side surfaces 545, the plurality of groove side surfaces 545 being connected to the groove bottom surface 544. One of the groove bottom surface 544 and the groove side surfaces 545 may be an arcuate surface, and the other of the groove bottom surface 544 and the groove side surfaces 545 may be a plane. See one example. Figure 1 At least one groove 54 has a bottom surface 544 that can be a plane, and a groove side surface 545 of the groove 54 can be an arc surface.

[0043] In some embodiments, please refer to Figure 1 and Figure 2Multiple grooves 54 are provided in the metal layer 51. Since metal has a certain strength, the grooves 54 on the metal layer 51 are not easily deformed, and the grooves 54 play a stable limiting role for the buffer 6.

[0044] In some embodiments, when the support structure 5 includes a metal layer 51 and a buffer layer 52, and a plurality of grooves 54 are provided at least in the metal layer 51, the thickness Th1 of the metal layer 51 can be greater than or equal to the thickness Th2 of the buffer layer 52. In this way, by utilizing the space saved in the thickness direction of the display assembly by the buffer member 6 disposed in the groove 54, the thickness of the metal layer 51 is increased, improving the support performance of the metal layer 51 for the display panel 1, etc., and reducing the overall warpage of the module composed of the display panel 1, etc. In some embodiments, the thickness of the metal layer 51 can be greater than the thickness of the buffer layer 52.

[0045] It should be noted that the thickness of metal layer 51 can refer to the maximum thickness of metal layer 51, and the thickness of buffer layer 52 can also refer to the maximum thickness of buffer layer 52.

[0046] In other embodiments, at least one groove 54 may extend into the buffer layer 52 to increase the depth of the groove 54, so that the height of the buffer 6 can be greater and the buffer 6 can have more cushioning performance.

[0047] In some embodiments, please refer to Figure 3 Multiple grooves 54 are spaced apart along one direction, and each groove 54 is provided with at least one corresponding buffer 6. In this way, the multiple grooves 54 and the multiple buffers 6 cooperate to provide stronger support along the extension direction of the grooves 54 and to transmit the stress generated by external impact along the extension direction of the grooves 54. In one example, the grooves 54 extend along a second direction Y, and the multiple grooves 54 are spaced apart along a first direction X, that is, the multiple grooves 54 are arranged spaced apart along the length of the display device 100. In another example, the grooves 54 may also extend along the first direction X, and the multiple grooves 54 may be spaced apart along the second direction Y.

[0048] In some embodiments, please refer to Figure 4 Multiple grooves 54 are arranged along multiple intersecting directions, and each groove 54 is provided with at least one corresponding buffer 6. In this way, the cooperation between the multiple grooves 54 and the multiple buffers 6 can provide uniform support for the display panel 1 and transmit the stress generated by external impact forces in multiple directions, making the stress and deformation of the multiple buffers 6 more uniform and improving their impact resistance. In one example, the multiple grooves 54 are arranged alternately along a first direction X and a second direction Y.

[0049] In some embodiments, please refer to Figures 1 to 4The plurality of grooves 54 include a first groove 542 and a second groove 543. The first groove 542 is located between two opposite side surfaces 533. The second groove 543 is positioned relative to the first groove 542 and closer to the side surface 533. The plurality of buffers 6 include a first buffer 62 and a second buffer 63. The first buffer 62 is located in the first groove 542. The second buffer 63 is located in the second groove 543. In this way, the second groove 543, in conjunction with the second buffer 63, can improve the impact resistance of at least two edge portions of the module composed of the display panel 1, etc. (including the display panel 1, cover plate 2, circular polarizer 3, and support structure 5); the first groove 542, in conjunction with the first buffer 62, can improve the impact resistance of the middle area between at least two opposite edges of the module composed of the display panel 1, etc., thereby improving the impact resistance of different positions of the entire module.

[0050] In some embodiments, please refer to Figure 3 Each first groove 542 and second groove 543 extends along the second direction Y. The plurality of first grooves 542 can be located between two side surfaces 533 and two second grooves 543 along the first direction X. The two second grooves 543 are respectively adjacent to the two side surfaces 533 in the first direction X.

[0051] Please see Figure 4 Multiple first grooves 542 may be located between two side surfaces 533 along a first direction X, and between another two side surfaces 533 along a second direction Y. Multiple second grooves 543 may be arranged around multiple first grooves 542.

[0052] In some embodiments, please refer to Figure 1 and Figure 3 The second groove 543 is fixed to the groove wall of the second groove 543. Along at least one direction parallel to the back surface, the dimension d1 of the second groove 543 is larger than the dimension d2 of the first groove 542. Since the second buffer member 63 is fixed to the groove wall of the second groove 543, the entire support structure 5 can be fixed using the second buffer member 63, reducing the risk of significant displacement of the support structure 5 under impact. Based on the second buffer member 63 being fixed to the groove wall of the second groove 543, the dimension d1 of the second groove 543 being larger than the dimension d2 of the first groove 542 along at least one direction parallel to the back surface is beneficial for increasing the dimension of the second groove 543 along at least one direction parallel to the back surface, thereby increasing the contact area between the second buffer member 63 and the groove wall of the second groove 543, increasing the contact force between the second buffer member 63 and the groove wall of the second groove 543, and thus facilitating a more stable fixation of the support structure 5 to the shell structure 4 using the second buffer member 63.

[0053] In some embodiments, please refer to Figure 1The bottom surface of the second groove 543 can be flat to securely fix the second buffer member 63 to the bottom surface of the second groove 543; the side surface of the second groove 543 can be arc-shaped, so that there is a gap S2 between the second buffer member 63 and the side surface 545 of the second groove 543, providing deformation space for the deformation of the second buffer member 63. The side wall of the first groove 542 can be arc-shaped.

[0054] In some embodiments, one or more buffer members 6 are in contact with the bottom wall of the housing structure 4, and one buffer member 6 is fixed to at least one of the bottom wall of the housing structure 4 and the supporting structure 5. In this way, the buffer member 6 can be fixed, and the buffer member 6 will deform under the action of impact force without significant movement.

[0055] In some embodiments, the first buffer member 62 may contact the bottom surface of the first groove 542, but the first buffer member 62 is not fixed to the groove wall of the first groove 542, but is fixed to the bottom wall of the housing structure 4. In other embodiments, the first buffer member 62 may be fixed to both the groove wall of the first groove 542 and the bottom wall 44 of the housing structure 4. In other embodiments, the first buffer member 62 may contact the bottom wall of the housing structure 4, but is not fixed to the bottom wall of the housing structure 4, but is fixed to the groove wall of the first groove 542. In some embodiments, the first buffer member 62 may not contact the bottom surface of the first groove 542, but is fixed to the bottom wall of the housing structure 4.

[0056] In some embodiments, the second buffer 63 can be fixed simultaneously to the groove wall of the second groove 543 and the bottom wall of the shell structure 4 to ensure that the support structure 5 is fixed to the shell structure 4 and reduce the risk of the support structure 5 moving relative to the shell structure 4.

[0057] In some embodiments, the first buffer 62 and the second buffer 63 may both be adhesive and thus fixed to the groove wall of the first groove 542 and the bottom wall of the shell structure 4 by themselves, or they may be fixed to the groove wall of the first groove 542 and the bottom wall of the shell structure 4 by independent adhesive layers.

[0058] In some embodiments, the hardness of the buffer 6 may be less than that of the buffer layer 52, thereby giving the buffer 6 better deformation capability in the groove 54. In some embodiments, the buffer 6 may include foam adhesive, so that the buffer 6 has both cushioning performance and adhesiveness.

[0059] In some embodiments, a buffer 6 may be cylindrical, ellipsoidal, hemispherical, spherical, frustum-shaped, or truncated cone-shaped. See also [link to embodiments]. Figure 1 and Figure 3When the groove 54 extends in one direction, the buffer 6 can be cylindrical. See also: [link to embodiments]. Figure 1 and Figure 4 When multiple grooves 54 are arranged in an array, a buffer 6 can be ellipsoidal.

[0060] In summary, in the display device of this application embodiment, one or more grooves are provided on the support structure, with the grooves recessed from the second surface into the first surface, and a buffer member located in a corresponding groove. Thus, when the display device is subjected to external impact, the buffer member in the groove can release the stress generated by the impact through deformation, thereby improving the impact resistance of the display device. In other words, the impact resistance of the display device is improved by utilizing the cooperation between the groove and the buffer member.
