[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0040] In the description of the embodiments of the present application, the term "and / or" refers to and covers any and all possible combinations of one or more of the associated listed items. The term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist.

[0041] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0043] In the related art, when the light source of the display device is irradiated onto the support member used to support the diffuser plate, due to reflection or refraction of the support member, the propagation path of the light emitted from the support member is different from the propagation path of the original light, resulting in uneven light distribution, thereby forming a shadow on the diffuser plate, thereby reducing the display quality of the display device.

[0044] See also Figure 1 , Figure 1 The cross section of the support member in the related art is formed into a circle, and when the light emitted by the light source passes through the support member, the direction of the emitted light has a tendency to converge, so that the light emitted from the support member is unevenly distributed.

[0045] In order to solve the above technical problems, an embodiment of the present application provides a display device.

[0046] See also Figure 2 and Figure 3 , Figure 2 A schematic diagram of a display device provided in some embodiments of the present application, Figure 3 The display device 100 is a cross-sectional view of a display device provided in some embodiments of the present application. The display device 100 may be a liquid crystal display device. The display device 100 may include a display panel 101 and a backlight module 102.

[0047] The display panel 101 may be used to display images, and the backlight module 102 may include a back plate 1. The back plate 1 may be arranged on a side away from the display surface of the display panel 101.

[0048] The display panel 101 is used to display image information such as text and images. The display panel 101 may include a display area and a circuit board located at one side of the display area, and the entire display panel 101 is driven and displayed through the circuit board.

[0049] The display panel 101 is a main component of the display device 100, which mainly includes a liquid crystal display panel, a color filter (CF) substrate of the liquid crystal display panel, a thin film transistor (TFT) substrate (also called an array substrate) and a liquid crystal (LC) layer, and the liquid crystal layer is located between the color filter substrate and the array substrate. Among them, the thin film transistor substrate is provided with data lines and scan lines, and the liquid crystal molecules are controlled to change direction by whether the data lines and the scan lines are powered on or not, so that the light of the light source 2 is emitted through the color filter substrate and a picture of a preset color is generated.

[0050] Since the liquid crystal display panel itself cannot emit light, in order to allow the display device 100 to display normally, the display device 100 may further include a backlight module 102, which may include a back plate 1 and a light source 2. The back plate 1 is arranged on a side away from the display surface of the display panel 101, and the back plate 1 has a supporting and bearing function. The light source 2 is used to generate light, and the light source 2 is configured to provide backlight to the display panel 101.

[0051] It can be understood that the backlight module 102 is used to provide sufficient brightness and evenly distributed backlight for the display panel 101 , and the display panel 101 can modulate the backlight as needed to display different images.

[0052] In some embodiments, the back plate 1 may be an aluminum plate, a printed circuit board (PCB), etc. The back plate 1 may be used to support the light source 2, and the back plate 1 may also heat the light source 2. The light source 2 may be a light emitting diode (LED), a sub-millimeter light emitting diode (Mini Light Emitting Diode, MiniLED) or a micron-level light emitting diode (Micro Light Emitting Diode, Micro LED).

[0053] There may be multiple light sources 2 , and the multiple light sources 2 may be disposed on a side of the back plate 1 facing the display panel 101 and spaced apart so that the light sources 2 can provide backlight for the display panel 101 .

[0054] The light source 2 may be a lamp bead or a light strip, etc., and a plurality of light sources 2 may be fixed on the back plate 1 by means of snap connection, thread connection, etc.

[0055] The backlight module 102 may further include a diffusion plate 3. The diffusion plate 3 may be arranged on a side of the light source 2 close to the display panel 101, and at a certain distance from the light source 2. That is, the diffusion plate 3 is arranged at intervals on a side of the light source 2 close to the display panel 101. The setting of this distance allows sufficient light mixing between the multiple light sources 2. Since the function of the diffusion plate 3 is to dissipate the heat of the incident light, the light passing through the diffusion plate 3 is made more uniform, thereby making the brightness of the display device 100 more uniform, which is conducive to reducing the phenomenon of uneven brightness.

[0056] The diffuser plate 3 may be provided with scattering particle materials. When light enters the scattering particle materials, it will be refracted and reflected continuously, thereby achieving the effect of scattering the light and realizing the effect of uniform light.

[0057] The diffuser plate 3 can be formed by an extrusion process.

[0058] Please continue reading Figure 3 , the backlight module 102 may further include a reflective sheet 7. The reflective sheet 7 may be disposed on a side of the back plate 1 close to the display panel 101. By providing the reflective sheet 7, the light emitted by the light source 2 may be reflected and guided to the surface of the display panel 101, which is beneficial to improving the brightness and contrast of the display device 100, and making the image displayed by the display device 100 clearer. At the same time, the reflective sheet 7 may also help control the direction of the light, thereby ensuring that the light can be evenly irradiated to the entire surface of the display panel 101, which is beneficial to improving the display effect of the display device 100.

[0059] Please continue reading Figure 3 The backlight module 102 may further include a transparent support member 4. One end of the transparent support member 4 abuts against the diffuser plate 3, and the other end is connected to the back plate 1. By providing the transparent support member 4, the light emitted by the light source 2 can pass through the transparent support member 4, and the diffuser plate 3 can be prevented from collapsing due to its own weight, thereby facilitating the diffusion effect of the diffuser plate 3 and the reliability of use.

[0060] It should be noted that the material of the transparent support member 4 may include one or more of epoxy resin, polystyrene, methyl methacrylate-styrene copolymer, polymethyl, methyl acrylate and the like.

[0061] See also Figure 3 and Figure 4 , Figure 4 A top view of a transparent support member provided in some embodiments of the present application. The outer contour of the cross section of the transparent support member 4 may be a hexagon. Specifically, the outer contour of the cross section of the transparent support member 4 may be a regular hexagon or an irregular hexagon.

[0062] The transparent support 4 may include six triangular prisms 41. The side surfaces of the six triangular prisms 41 are connected end to end in sequence, and there is a gap 42 between two adjacent triangular prisms 41. Specifically, the side surfaces of the six triangular prisms 41 are the outer surfaces of the transparent support 4, and the outer contour of the orthographic projection of the side surfaces of the six triangular prisms 41 on the back plate 1 is a hexagon, and there is a spacing between any two triangular prisms 41, that is, there is a spacing between the opposite sides of two adjacent triangular prisms 41.

[0063] When the light emitted by the light source 2 is directed toward the transparent support 4, the light may first be refracted in the first triangular prism 41, then directed toward the gap 42 between the adjacent first triangular prism 41 and the second triangular prism 41, and then directed toward the second triangular prism 41, thereby being refracted for the second time, and then directed toward the second triangular prism 41 for the third time, and finally directed toward the gap 42 between the adjacent second triangular prism 41 and the third triangular prism 41, and then directed toward the third triangular prism 41, thereby being refracted for the fourth time, and then directed toward the third triangular prism 41 for the fifth time before being emitted from the transparent support 4. Thus, the direction of the light emitted by the light source 2 into the transparent support 4 can be changed through multiple refractions, so that the direction of the light emitted by the light source 2 into the transparent support 4 can be parallel to the direction of the light emitted from the transparent support 4, thereby ensuring that the light emitted by the light source 2 can be evenly distributed through the thickness of the transparent support 4, so that the shadow phenomenon on the diffusion plate 3 can be improved, which is beneficial to improving the display quality of the display device 100.

[0064] Here, parallel means roughly parallel, and there can be a certain range of error.

[0065] According to the display device 100 of the embodiment of the present application, by making the outer contour of the cross section of the transparent support member 4 a hexagon, and making the side surfaces of the six triangular prisms 41 of the transparent support member 4 connected end to end in sequence, and making a gap 42 between two adjacent triangular prisms 41, the direction of the light emitted by the light source 2 into the transparent support member 4 can be made parallel to the direction of the light emitted from the transparent support member 4, thereby reducing the phenomenon that the light emitted from the transparent support member 4 forms a shadow on the diffuser 3, so that the light can evenly illuminate the surface of the entire display panel 101, which is beneficial to improving the display effect and display quality of the display device 100.

[0066] In some embodiments, the backlight module 102 may include a plurality of transparent support members 4. The plurality of transparent support members 4 are arranged at intervals on the back plate 1. Since the transparent support member 4 can change the direction of the light emitted by the transparent support member 4, the positions of the plurality of transparent support members 4 can be changed according to the rationality of supporting the diffusion plate 3 or according to the actual layout requirements of the display device 100, so that the structural design of the display device 100 can be better optimized.

[0067] Please continue reading Figure 3 and Figure 4 In some embodiments, the cross section of the triangular prism 41 may be an equilateral triangle. Thus, the transparent support 4 can be ensured to better change the direction of the light emitted from the light source 2 to the transparent support 4, thereby ensuring that the light emitted from the transparent support 4 can be evenly distributed, which is beneficial to ensuring the display quality of the display device 100 and improving the user experience.

[0068] It should be noted that the cross section of the triangular prism 41 may also be formed as an irregular triangle, and the present application does not impose any limitation on this.

[0069] Please continue reading Figure 3 and Figure 4 In some embodiments, the outer contour of the cross section of the transparent support 4 can be a regular hexagon. Thus, the direction of the light from the light source 2 entering the transparent support 4 from all angles can be parallel to the direction of the light emitted from the transparent support 4, thereby further ensuring that the light emitted from the transparent support 4 can be evenly distributed, which is more conducive to ensuring the display quality of the display device 100 and improving the user experience.

[0070] Please continue reading Figure 3 and Figure 4 In some embodiments, the transparent support member 4 may have a cavity 43. The side edges of the six triangular prisms 41 close to the cavity 43 are arranged at intervals around the circumference of the cavity 43. Specifically, the side edges of the six triangular prisms 41 close to the cavity 43 may be arranged at uniform intervals around the circumference of the cavity 43. The side edges of the six triangular prisms 41 close to the cavity 43 may also be arranged at uneven intervals around the circumference of the cavity 43. Such an arrangement can avoid the convergence of light emitted from the transparent support member 4, and can ensure that the light emitted from the transparent support member 4 can be evenly distributed, which is conducive to ensuring the display quality of the display device 100.

[0071] See also Figure 5 , Figure 5 The top view of the transparent support member provided in some other embodiments of the present application. Exemplarily, the side edges of the six triangular prisms 41 that are not adjacent to each other and close to the cavity 43 can be connected. Such an arrangement is conducive to ensuring the display quality of the display device 100.

[0072] See also Figure 6 , Figure 6A partial stereoscopic diagram of a display device provided for some embodiments of the present application. In some embodiments, the backlight module 102 may further include a substrate 5. The substrate 5 may be located on a side of the back plate 1 close to the display panel 101, and may be detachably connected to the back plate 1. The transparent support member 4 is disposed on a side of the substrate 5 close to the display panel 101. Specifically, the substrate 5 and the back plate 1 may be detachably connected by means of snap-fitting, fastener connection, or the like. By making the substrate 5 connected to the transparent support member 4 detachably connected to the back plate 1, it is convenient to replace and repair the substrate 5 and the transparent support member 4, which is beneficial to reducing the maintenance cost of the display device 100 and making the display device 100 more maintainable.

[0073] Exemplarily, the orthographic projection of the transparent support 4 on the back plate 1 may be located within the orthographic projection of the substrate 5 on the back plate 1. Thus, the transparent support 4 can increase the contact area with the back plate 1 through the substrate 5, so that the transparent support 4 can be better fixed on the back plate 1, and the possibility of the transparent support 4 breaking can be reduced.

[0074] For example, the transparent support member 4 and the substrate 5 may be an integrally formed member. This arrangement is beneficial to improving the assembly efficiency of the display device 100.

[0075] See also Figure 7 and Figure 8 , Figure 7 A partial top view of a display device provided in some embodiments of the present application, Figure 8 A partial cross-sectional view of a display device provided in some embodiments of the present application. In some embodiments, a first clamping hole 51 and a second clamping hole 52 may be formed on the substrate 5. The first clamping hole 51 and the second clamping hole 52 are connected, and the aperture of the first clamping hole 51 is larger than the aperture of the second clamping hole 52. A clamping portion 11 is formed on the back plate 1, and the clamping portion 11 is clamped and matched with the second clamping hole 52. Specifically, when the substrate 5 is connected to the back plate 1, the clamping portion 11 on the back plate 1 extends into the first clamping hole 51, and the clamping portion 11 extends into the second clamping hole 52 through the connection between the first clamping hole 51 and the second clamping hole 52, so that the second clamping hole 52 is clamped and matched with the clamping portion 11, thereby connecting the substrate 5 to the back plate 1.

[0076] Therefore, the base plate 5 and the back plate 1 can be detachably connected through the snap-fitting cooperation between the snap-fitting portion 11 and the second snap-fitting hole 52 . The connection method is simple and easy to assemble, which is beneficial to improving the assembly efficiency of the display device 100 .

[0077] It should be noted that the back plate 1 may be provided with a first clamping hole 51 and a second clamping hole 52 , and the base plate 5 may be provided with a clamping member that is clamped and matched with the second clamping hole 52 , and the present application does not impose any limitation on this.

[0078] Exemplarily, the clamping portion 11 can be formed by stamping the back plate 1. This arrangement is conducive to reducing the difficulty of manufacturing the back plate 1.

[0079] Please continue reading Figure 7 and Figure 8 In some embodiments, a positioning hole 53 may be formed on the substrate 5. The positioning hole 53 is spaced apart from the first clamping hole 51 and the second clamping hole 52. A positioning portion 12 may be formed on the back plate 1. The positioning portion 12 is engaged with the positioning hole 53. Specifically, when the substrate 5 is connected to the back plate 1, the clamping portion 11 is first extended into the first clamping hole 51, and then the clamping portion 11 is moved toward the second clamping hole 52. When the positioning portion 12 is engaged with the positioning hole 53, the clamping portion 11 and the second clamping hole 52 can be engaged.

[0080] Therefore, the positioning portion 12 and the positioning hole 53 can cooperate to make the clamping portion 11 and the second clamping hole 52 directly assembled, which is helpful to reduce the difficulty of assembly and also can improve the reliability of the connection between the back plate 1 and the substrate 5.

[0081] It should be noted that the back plate 1 may be provided with a positioning hole 53 , and the base plate 5 may be provided with a clamping piece that is engaged with the positioning hole 53 , and the present application does not impose any limitation on this.

[0082] Exemplarily, the positioning portion 12 may also be formed by stamping the back plate 1. This arrangement is conducive to reducing the difficulty of manufacturing the back plate 1.

[0083] See also Fig. 9 and Fig.10 , Fig. 9 Partial stereograms of display devices provided in some other embodiments of the present application, Fig.10 Partial top view of a display device provided for other embodiments of the present application. In some embodiments, the backlight module 102 may further include an elastic support member 6. The elastic support member 6 has a first end and a second end opposite to each other. The first end is connected to the substrate 5. The second end is connected to the transparent support member 4. The spacing between the first end and the second end changes when the elastic support member 6 is subjected to pressure. Specifically, compression deformation may occur when the elastic support member 6 is subjected to pressure. The deformation may be restored after the external force is removed.

[0084] Therefore, when the user performs a touch operation or during transportation, the diffuser plate 3 will move toward the direction close to the back plate 1, and the elastic support member 6 will be compressed. Since the elastic support member 6 can be deformed, it can avoid a large fluctuation deformation between the display panel 101 and the diffuser plate 3, which is beneficial to improve the structural stability of the display device 100. At the same time, it can also reduce the possibility of the transparent support member 4 breaking, which is beneficial to improve the service life of the transparent support member 4.

[0085] The elastic supporting member 6 can be detachably connected to the substrate 5 by means of snap connection, fastener connection, etc., or fixedly connected to the substrate 5 by means of adhesive, etc., or the elastic supporting member 6 can be integrally formed with the substrate 5 and the transparent support member 4. The elastic supporting member 6 can be made of a transparent material, for example, fiberglass, etc.

[0086] Please continue reading Fig. 9 and Fig.10 In some embodiments, the elastic supporting member 6 may include a deformation portion 61 and a connecting portion 62. The transparent supporting member 4 may be arranged on a side of the connecting portion 62 close to the display panel 101, and the two opposite ends of the connecting portion 62 are connected with the deformation portion 61. The deformation portion 61 is arranged at the edge of the substrate 5, and the deformation portion 61 extends in a direction close to the diffuser plate 3. Thus, the space between the connecting portion 62 and the back plate 1 can be hollow, so that the range of deformation of the elastic portion can be increased. At the same time, since the deformation portion 61 is arranged at the edge of the substrate 5, the supporting capacity of the elastic supporting portion for the transparent supporting member 4 can be improved.

[0087] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
