Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] In the field of display technology, the module structure within a display device is a crucial factor influencing the bezel width. As the display device market continues to develop, users are increasingly demanding narrower bezels in order to achieve a larger screen-to-body ratio and a better visual experience.

[0003] In display devices, the back panel and the frame are important components. They are mainly used to fix and support the display panel, and can also withstand impacts, so that the display panel can display images normally.

[0004] However, as the bezel width of display devices becomes smaller and smaller, there is no space in the bezel area to install a plastic frame barrier, especially on the bonding side of the display device. The array substrate is designed to protrude because it needs to bond the driver chip, which makes the single-layer glass more prone to cracking, affecting the stability and lifespan of the display device.

[0027] 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.

[0028] Please refer to Figure 1 In related technologies, a display device may include a panel body 1 and a backlight structure 2, and the backlight structure 2 may be disposed in a frame 3, while the panel body 1 is located on the light-emitting side of the backlight structure 2 and may be placed on the frame 3; as the demand for narrow bezels in display devices increases, the bezel space of display devices gradually decreases, resulting in no space in the bezel area of ​​the display device to set up a plastic frame barrier, and thus the display device is prone to breakage under the impact of external forces.

[0029] For example, the panel body 1 may include an array substrate 4 and a color filter substrate 5 arranged opposite to each other. On the bonding side of the display device, the array substrate 4 needs to bond the driver chip 6. Therefore, the array substrate 4 will bulge outward relative to the color filter substrate 5. As a result, the area where the driver chip 6 is bonded is only a single-layer glass substrate, which is more likely to break under impact, seriously affecting the stability and lifespan of the display device.

[0030] Please refer to Figure 2This application provides a display device, which includes a display area 101 and a binding area 102 located on at least one side of the display area 101; the display device includes a display panel 10, a support structure 20 and a back plate 40.

[0031] The display panel 10 includes a first substrate 11 and a second substrate 12 disposed opposite to each other. The second substrate 12 is located on the side of the first substrate 11 near the display surface 1011 of the display panel 10. The first substrate 11 includes a first surface 111 near the second substrate 12 and a first side surface 112 connected to the first surface 111. The first substrate 11 is located in the display area 101 and the bonding area 102, and the second substrate 12 is located outside the bonding area 102. A back plate 40 is disposed on the side of the first substrate 11 away from the second substrate 12. A support structure 20 is disposed at least on the first side surface 112 of the first substrate 11. The support structure 20 is located on the side of the bonding area 102 away from the display area 101 and is connected to the back plate 40.

[0032] The support structure 20 includes a top end 201 near the side of the display surface 1011, and the horizontal plane where the top end 201 is located is between the horizontal plane where the first surface 111 is located and the horizontal plane where the display surface 1011 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the display surface 1011 is located.

[0033] In the implementation process, this application embodiment adds a support structure 20 at the first side 112 of the first substrate 11, and the first substrate 11 includes a first surface 111 near the second substrate 12; the horizontal plane where the top end 201 of the support structure 20 is located is between the horizontal plane where the first surface 111 is located and the horizontal plane where the display surface 1011 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the display surface 1011 is located; that is, the top end 201 protrudes from the first surface 111, so the support structure 20 can at least protect and resist the impact of the first substrate 11, effectively reducing the probability of the first substrate 11 breaking; thus, this application can improve the impact resistance of the display device, reduce the probability of the display device breaking, and improve the stability and lifespan of the display device.

[0034] Specifically, please refer to Figure 1 The display device provided in this application includes a display panel 10, a back plate 40, and a backlight module 50. The backlight module 50 can be disposed in the back plate 40, and the display panel 10 is located on the light-emitting side of the backlight module 50. The display panel 10 can be placed on the back plate 40. The back plate 40 can be used to accommodate and fix the backlight module 50, and can be used to support the display panel 10.

[0035] In some embodiments, the display panel 10 may include a first substrate 11 and a second substrate 12 disposed opposite to each other, a first polarizer 13 located on the side of the first substrate 11 away from the second substrate 12, and a second polarizer 14 located on the side of the second substrate 12 away from the first substrate 11; wherein, a thin film transistor array layer is disposed on the side of the first substrate 11 near the second substrate 12, and a color filter layer may be disposed on the side of the second substrate 12 near the first substrate 11.

[0036] In some embodiments, the display panel 10 may further include a liquid crystal layer disposed between the thin-film transistor array layer and the color filter layer.

[0037] It is understood that the first substrate 11 can be an array substrate, and the second substrate 12 can be a color filter substrate; furthermore, the first substrate 11 is located between the backlight module 50 and the second substrate 12.

[0038] In some embodiments, the back plate 40 includes a bottom plate 41, a side plate 42 connected to the bottom plate 41 and extending toward the first substrate 11, and a support plate 43 connected to the side of the side plate 42 away from the bottom plate 41.

[0039] It should be noted that the direction along the thickness of the display panel 10 is defined as the first direction X, and the direction perpendicular to the thickness of the display panel 10 is defined as the second direction Y.

[0040] The side plate 42 is connected to the periphery of the base plate 41 and extends along the first direction X. The side plate 42 can enclose the base plate 41 on the side near the first substrate 11 to form a receiving cavity. The backlight module 50 can be disposed in the receiving cavity.

[0041] The support plate 43 is connected to the end of the side plate 42 away from the bottom plate 41, and the support plate 43 can extend along the second direction Y. The display panel 10 can be disposed on the side of the support plate 43 away from the side plate 42, so that the support plate 43 can provide support for the display panel 10. The first substrate 11 can be located on the side of the support plate 43 away from the side plate 42.

[0042] In some embodiments, the backlight module 50 includes a reflective sheet 53 disposed in a receiving cavity and may be disposed on a base plate 41, a light guide plate 54 disposed on the side of the reflective sheet 53 away from the base plate 41, and a plurality of optical films disposed on the side of the light guide plate 54 away from the reflective sheet 53. For example, the plurality of optical films may include a first optical film 55, a second optical film 56, and a third optical film 57, and the first optical film 55, the second optical film 56, and the third optical film 57 may each be independently selected from any one of a diffusion film, a prism sheet, and a brightness enhancement film.

[0043] In some embodiments, the backlight module 50 further includes a light-emitting component 51 and a backlight driving component 52. The light-emitting component 51 is disposed on the side of the light guide plate 54 and emits light toward the light guide plate 54. One end of the backlight driving component 52 is connected to the light-emitting component 51, and the other end extends outside the receiving cavity.

[0044] In some embodiments, the backlight driving assembly 52 includes a first circuit board 521, a second circuit board 522, and a fixing member 523. The first end of the first circuit board 521 is connected to the light-emitting assembly 51, the second end of the first circuit board 521 extends outside the receiving cavity, and the second circuit board 522 is connected to the second end. The first circuit board 521 and the second circuit board 522 are fixedly connected by the fixing member 523, which can improve the connection reliability between the first circuit board 521 and the second circuit board 522 and improve the phenomenon of abnormal noise caused by wrinkles in the first circuit board 521.

[0045] In some embodiments, the first circuit board 521 can be an FPC flexible circuit board, the second circuit board 522 can be a PCB circuit board, and the fastener 523 can be a threaded part.

[0046] In this embodiment, the second substrate 12 is located on the side of the first substrate 11 away from the backlight module 50. That is, the second substrate 12 is located on the side of the first substrate 11 close to the display surface 1011 of the display panel 10. The first substrate 11 includes a first surface 111 close to the side of the second substrate 12 and a first side surface 112 connected to the first surface 111. The second substrate 12 includes a second surface 121 away from the side of the first substrate 11.

[0047] It should be noted that the display surface 1011 of the display panel 10 is the outermost surface of the display panel 10. In other words, the display surface 1011 is the outermost surface of the display panel 10 on the side away from the backlight module 50.

[0048] It is understandable that the display surface 1011 can be the surface of the second polarizer 14 away from the second substrate 12.

[0049] The display device also includes a support structure 20, which is disposed at least on the first side surface 112 of the first substrate 11. The support structure 20 includes a top end 201 near the display surface 1011, and the horizontal plane of the top end 201 is located between the horizontal plane of the first surface 111 and the horizontal plane of the display surface 1011, or the horizontal plane of the top end 201 is coplanar with the horizontal plane of the display surface 1011. This application embodiment adds a support structure 20 to the first side 112 of the first substrate 11, and the first substrate 11 includes a first surface 111 near the second substrate 12; the horizontal plane where the top end 201 of the support structure 20 is located is between the horizontal plane where the first surface 111 is located and the horizontal plane where the display surface 1011 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the display surface 1011 is located; that is, the top end 201 protrudes from the first surface 111, so the support structure 20 can at least protect and resist the impact of the first substrate 11, effectively reducing the probability of the first substrate 11 breaking; thus, this application can improve the impact resistance of the display device, reduce the probability of the display device breaking, and improve the stability and lifespan of the display device.

[0050] In some embodiments, the horizontal plane where the top end 201 is located is between the horizontal plane where the first surface 111 is located and the horizontal plane where the second surface 121 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the second surface 121 is located.

[0051] It is understood that the top end 201 does not extend beyond the second surface 121 of the second substrate 12, and thus the support structure 20 will not interfere with other structures above the second substrate 12.

[0052] In one embodiment, the display device includes a display area 101 and a bonding area 102 located on at least one side of the display area 101. The display device also includes a display driving component 30 disposed in the bonding area 102, and a support structure 20 is located on the side of the bonding area 102 away from the display area 101.

[0053] In this embodiment, the first substrate 11 is located in the display area 101 and the bonding area 102. The second substrate 12 is located at least within the display area 101 and outside the bonding area 102. The display driving component 30 is disposed on the first surface 111 and has a third surface 31 on the side away from the first surface 111. The horizontal plane where the top end 201 is located is between the horizontal plane where the third surface 31 is located and the horizontal plane where the display surface 1011 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the third surface 31 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the display surface 1011 is located. That is to say, the top end 201 of the support structure 20 added in this application embodiment can be higher than or flush with the third surface 31 of the display driving component 30, so that while protecting and resisting impact on the first substrate 11, it can also protect and resist impact on the display driving component 30.

[0054] Furthermore, in some embodiments, the horizontal plane where the top end 201 is located is between the horizontal plane where the third surface 31 is located and the horizontal plane where the second surface 121 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the third surface 31 is located, or the horizontal plane where the top end 201 is located is coplanar with the horizontal plane where the second surface 121 is located.

[0055] It should be noted that since the display panel 10 has only one glass substrate, the first substrate 11, in the bonding area 102, its impact resistance is poor. Therefore, in this embodiment of the application, by adding a support structure 20 to the side of the bonding area 102 away from the display area 101, the probability of the first substrate 11 breaking can be effectively reduced. In addition, in other embodiments of this application, the support structure 20 can also be provided on other sides of the display panel, such as other non-bonding sides, or the support structure 20 can be provided on all sides of the display panel.

[0056] In some embodiments, the material of the support structure 20 includes a metal material, such as stainless steel. Compared with related technologies, metal materials have high rigidity and good support, which can provide better protection and impact resistance for the display panel 10. At the same time, the support structure 20 provided in this application embodiment is made of a metal material, which can reduce the thickness compared with the frame while ensuring a considerable impact resistance, thus making it more advantageous for the support structure 20 to be used in narrow bezel display devices.

[0057] It should be noted that the support structure 20 provided in this application embodiment can be used to protect and resist impact on the display panel 10 and the display driving component 30, and the support structure 20 can be fixedly connected to the back plate 40 to improve the stability of the support structure 20.

[0058] In one specific embodiment of this application, please refer to Figure 2 The support structure 20 includes a first support portion 21 extending along the first direction X. The first support portion 21 overlaps with the first side surface 112 along the second direction Y, and the first support portion 21 has a top end 201 near the display surface 1011. That is, the first support portion 21 is the part of the support structure 20 that is used to protect and resist impacts to the display panel 10 and the display driving assembly 30.

[0059] The first support portion 21 includes a first sub-portion 211 extending along the first direction X, a second sub-portion 212 extending along the first direction X, and a third sub-portion 213 connecting the first sub-portion 211 and the second sub-portion 212; further, the first sub-portion 211 overlaps with the first side surface 112 along the second direction Y, the second sub-portion 212 overlaps with the first side surface 112 along the second direction Y, and the top end 201 is located on the first sub-portion 211, the second sub-portion 212, or the third sub-portion 213.

[0060] It should be noted that the first support portion 21 can be in a double-fold shape, that is, the first support portion 21 can extend towards the display surface 1011, then bend 180° and extend away from the display surface 1011, such as... Figure 2 As shown, at this time, the top end 201 can be located on the third sub-part 213. Alternatively, the first support part 21 can be H-shaped, with the first sub-part 211 and the second sub-part 212 located on opposite sides, and the third sub-part 213 connected between the first sub-part 211 and the second sub-part 212, which is not shown in the figures provided in this application embodiment.

[0061] As mentioned above, the first support portion 21 provided in this application embodiment can adopt a double-fold shape or an H-shape, which can effectively improve the support strength and rigidity of the support structure 20, and further improve the protection and impact resistance of the support structure 20 for the display panel 10 and the display driving component 30.

[0062] In some embodiments, the first support portion 21 and the first side surface 112 are spaced apart, which can reserve a buffer space between the first support portion 21 and the first side surface 112. When the display device is impacted, the support structure 20 can be given space to buffer stress, so as to avoid squeezing and collision between the support structure 20 and the first substrate 11.

[0063] In some embodiments, the support structure 20 further includes a second support portion 22 connected to the first support portion 21. The second support portion 22 extends along the second direction Y and is located on the side of the first substrate 11 away from the second substrate 12.

[0064] The second support portion 22 is located between the first substrate 11 and the back plate 40. Furthermore, the second support portion 22 is located between the first substrate 11 and the support plate 43 to support the display panel 10.

[0065] In some embodiments, the display device includes an adhesive layer disposed between the second support portion 22 and the support plate 43, and the adhesive layer may be double-sided adhesive, so that the second support portion 22 may be attached to the support plate 43 to fix the support structure 20.

[0066] In addition, in some other embodiments, the second support 22 can also be connected to the support plate 43 by welding, which can increase the stability of the support structure 20 and also help meet the requirements of the display device to be thinner and lighter.

[0067] In some embodiments, the display device further includes a functional coating disposed on the side of the second support portion 22 near the first substrate 11, and the elastic modulus of the functional coating is less than the elastic modulus of the second support portion 22; that is, by providing a more flexible functional coating on the side of the second support portion 22 near the first substrate 11, the present application embodiment can not only support the first substrate 11, but also buffer stress, thereby further improving the protection and impact resistance of the support structure 20.

[0068] In some embodiments, the material of the functional coating includes a light-shielding material; further, the material of the functional coating may be black polyethylene terephthalate.

[0069] Furthermore, the support structure 20 also includes a third support portion 23 connected to the first support portion 21. The third support portion 23 extends along the first direction X and overlaps with the side plate 42 along the second direction Y. That is, the third support portion 23 is located on the side of the side plate 42 away from the backlight module 50. The third support portion 23 is in contact with the side plate 42. That is, the support structure 20 can also extend downward to the side of the side plate 42 away from the backlight module 50 and contact the side plate 42. Thus, when the display device is impacted, the third support portion 23 can abut against the side plate 42, and the side plate 42 provides further support to the support structure 20 to enhance the impact resistance of the support structure 20.

[0070] Continuing from the above, in this embodiment, the support structure 20 can be made of stainless steel, and one end of the support structure 20 is located on the side of the side plate 42 away from the backlight module 50, and the other end of the support structure 20 extends toward the display surface 1011, and is bent and rotated 180° at the side of the display panel 10, and then extends along the second direction Y at the support plate 43 to between the first substrate 11 and the support plate 43.

[0071] In another specific embodiment of this application, please refer to Figure 3 This embodiment and Figure 2 The difference in the embodiment shown is that the first support 21 is a single-layer structure and extends along the first direction X.

[0072] The support structure 20 includes a second support portion 22 connected to the first support portion 21 and extending along the second direction Y to the space between the first substrate 11 and the support plate 43. However, the support structure 20 in this embodiment does not have a third support portion 23, so that the support structure 20 is L-shaped as a whole.

[0073] Furthermore, in this embodiment, a first opening is provided on the side plate 42, one end of the backlight driving component 52 is connected to the light-emitting component 51, and the other end of the backlight driving component 52 passes through the first opening and is located outside the receiving cavity.

[0074] In some embodiments, the third support portion 23 has a second opening corresponding to the first opening, and the other end of the backlight driving assembly 52 also passes through the second opening, such as... Figure 2 As shown.

[0075] In other embodiments, if the distance by which the third support portion 23 extends in the direction away from the display surface 1011 does not reach the first opening, then the third support portion 23 will not affect the outward extension of the backlight driving component 52, and a second opening will not be provided in the third support portion 23.

[0076] Or, such as Figure 3 As shown, the support structure 20 does not have a third support part 23, so the support structure 20 will not affect the outward extension of the backlight driving component 52.

[0077] In some embodiments, such as Figure 7 As shown, the display device also includes a first housing 61 disposed on the side of the second substrate 12 away from the first substrate 11, and the first housing 61 is located on the side of the support structure 30 close to the display surface 1011; in addition, the display device may also include a second housing 62 disposed on the side of the backlight module 50 away from the display surface 1011.

[0078] In addition, comparative examples 1 and 2, as well as embodiments, are provided in this application to verify the protection and impact resistance of the support structure 20 provided in this application.

[0079] In Comparative Example 1, the following method is used: Figure 5 The structure shown includes a first housing 61 and a second housing 62 formed on opposite sides of the display device, and Figure 5 Display device and Figure 2 The difference in the display device shown is that it does not have a support structure 20.

[0080] In Comparative Example 2, the following method is used: Figure 6 The structure shown includes a first housing 61 and a second housing 62 formed on opposite sides of the display device, and relative to... Figure 5 The structure shown has a frame 63 added to the side of the back panel 40 away from the backlight module 50 for support.

[0081] In the embodiments, the following are employed: Figure 7 The structure shown, specifically in Figure 2 The display device shown has a first housing 61 and a second housing 62 formed on opposite sides.

[0082] Then, stress impact tests were performed on Comparative Example 1, Comparative Example 2, and the Example, and the results were as follows: Figure 8 , Figure 9 as well as Figure 10 The stress simulation diagram shown below and the data shown in Table 1 below, in which, Figure 8 The stress simulation diagram is shown for the structure in Comparative Example 1. Figure 9 The stress simulation diagram is shown for the structure in Comparative Example 2. Figure 10 The image shows a stress simulation diagram corresponding to the structure in the embodiment.

[0083] Table 1

[0084] In Table 1, the stress comparisons are the stress percentages obtained by comparing Comparative Example 2 and the Example with Comparative Example 1 as a reference.

[0085] Depend on Figures 8 to 10 As can be seen from Table 1, the stress experienced in Comparative Example 2 was reduced by 13.6% compared to Comparative Example 1, and the stress experienced in the embodiment was reduced by 21.5% compared to Comparative Example 1. Therefore, by adopting the support structure 20 in the embodiment of this application, the stress experienced by the first substrate 11 can be effectively reduced, the stress impact experienced by the display panel 10 can be reduced, and the impact resistance is better than that of the frame 63 in the related technology.

[0086] In summary, this application embodiment adds a support structure 20 to the first side 112 of the first substrate 11, and the first substrate 11 includes a first surface 111 near the second substrate 12, and the second substrate 12 includes a second surface 121 away from the first substrate 11; the horizontal plane of the top end 201 of the support structure 20 is located between the horizontal plane of the first surface 111 and the horizontal plane of the second surface 121, or the horizontal plane of the top end 201 is coplanar with the horizontal plane of the second surface 121; that is, the top end 201 protrudes from the first surface 111, and thus the support structure 20 can at least protect and resist the impact of the first substrate 11, effectively reducing the probability of the first substrate 11 breaking; therefore, this application can improve the impact resistance of the display device, reduce the probability of the display device breaking, and improve the stability and lifespan of the display device.
