[0038] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0040] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual proportions, and are only intended to illustrate the contents of the utility model. The same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.
[0041] Liquid crystal display devices have the advantages of being thin, light, power-saving and radiation-free, and have been widely used in various electronic products such as notebook computers, digital cameras, digital camcorders, mobile phones, computer monitors and LCD televisions.
[0042] The liquid crystal display device includes a liquid crystal display panel. Since the liquid crystal display panel is a non-self-luminous display panel, it needs the light source provided by the backlight module to produce a display function, that is, the liquid crystal display device also includes a backlight module.
[0043] The display principle of the liquid crystal display panel is to place the liquid crystal between two pieces of conductive glass, and rely on the electric field between the two electrodes to drive the electric field effect of the liquid crystal molecules to distort, so as to control the transmission or shielding function of the backlight source, thereby displaying the image. If a color filter is added, a color image can be displayed.
[0044] At present, the commonly used backlight modules include edge-entry backlight modules and direct-type backlight modules. The direct-type backlight module has the advantage of high brightness. A diffuser bracket is usually provided in the direct-type backlight module to support the diffuser and prevent the diffuser from collapsing and deforming. However, there is a problem that the shadow of the diffuser bracket is relatively obvious. In order to avoid affecting the subjective viewing effect, a thicker optical film or a more expensive optical film needs to be used for shielding, resulting in a higher production cost.
[0045] In order to overcome the above problems, the present invention provides a display device. Figure 1 This is a schematic diagram of the cross-sectional structure of a display device provided by an embodiment of the utility model. Figure 1 As shown, the display device includes: a display panel 1 and a backlight module 2.
[0046] The display panel 1 is used for displaying images.
[0047] For example, the display panel 1 can be generally configured as a rectangle, and when applied to a special-shaped display device, its shape is adapted to the shape of the display device. The size of the display panel 1 is generally matched with the backlight module 2 .
[0048] In a specific embodiment, the display panel 1 may be the above-mentioned liquid crystal display panel.
[0049] The backlight module 2 is disposed on the light incident side of the display panel 1 and is used to provide backlight for the display panel 1 .
[0050] The backlight module 2 is usually located at the bottom of the display device, and its shape and size are adapted to the shape and size of the display device. When applied to fields such as televisions or mobile terminals, the backlight module usually adopts a rectangular shape.
[0051] like Figure 1 As shown, the backlight module 2 includes: a back plate 21 , a light bar 22 , a diffusion plate 25 , a diffusion plate bracket 23 , a reflective sheet 24 and an optical film 26 .
[0052] The back plate 21 has supporting and bearing functions.
[0053] Exemplarily, the back plate 21 may be located at the bottom of the backlight module 2 , and the back plate 21 is used to support the light bar 22 , and to support and fix the edge positions of components such as the diffusion plate 2 and the optical film 4 .
[0054] The back plate 21 is generally a square structure, and when applied to a special-shaped display device, its shape is adapted to the shape of the display device. The shape of the back plate 21 is adapted to the shape of the backlight module 2 .
[0055] The material of the back plate 21 can be aluminum, iron, aluminum alloy or iron alloy, etc. The back plate 21 can also play a role in heat dissipation.
[0056] Figure 2 This is one of the schematic diagrams of the top view structure of the display device provided in the embodiment of the utility model, Figure 3 This is one of the side structural schematic diagrams of the display device provided by the embodiment of the utility model, Figure 4 The second schematic diagram of the top view structure of the display device provided by the embodiment of the utility model is as follows: Figure 5 This is a second schematic side view of the structure of the display device provided in an embodiment of the utility model.
[0057] like Figure 2 and Figure 4 As shown, the light bar 22 is located on the back panel 21 and serves as the backlight source of the backlight module 1. The light bar 22 includes: a strip circuit board 221 and a plurality of light-emitting devices 222. The strip circuit board 221 extends along a first direction F1, and the plurality of light-emitting devices 222 are arranged in sequence on the strip circuit board 221.
[0058] The light strip can be fixed on the back plate 2 by means of screws or other connectors, or the light strip can be pasted on the back plate 2 .
[0059] Exemplarily, multiple driver ICs can be integrated on the light bar to divide the light source into multiple dimming areas to achieve regional dimming. In the backlight module that applies regional dimming technology, the light-emitting device can use LED (Light Emitting Diode, LED for short), Mini LED (Mini-Light Emitting Diode, Mini LED for short), Micro LED (Micro Light Emitting Diode, Micro LED for short), etc. For example, Mini LED is used, because Mini LED has the advantages of small size and high brightness. More light-emitting devices can be set on the light board or light bar of the same area, providing higher backlight brightness and more delicate zoning control effect. When applied to different display devices and usage requirements, other types of light-emitting devices can also be used, which are not limited here.
[0060] The diffuser 25 is located on the light-emitting side of the light bar 22 and is used to diffuse the incident light. The diffuser 25 and the light bar 22 are at a certain distance, which is the OD value. The diffuser 25 can diffuse the incident light, thereby fully mixing the emitted light of the light bar 22, so that the light emitted after passing through the diffuser 25 is more uniform.
[0061] For example, the diffuser 25 is provided with scattering particle materials, and the light incident on the scattering particle materials will be refracted and reflected continuously, thereby achieving the effect of breaking up the light and achieving the effect of uniform light. The thickness of the diffuser is usually set to 0.5mm-3mm. The thicker the diffuser, the greater the haze and the better the uniform effect.
[0062] For example, the diffuser plate 25 may be processed by extrusion process, and the material used for the diffuser plate 25 may include at least one of polymethyl methacrylate PMMA, polycarbonate PC, polystyrene PS, and polypropylene PP.
[0063] For example, the diffuser plate may be square or rectangular in shape as a whole. When applied to a special-shaped display device, its shape and size are adapted to the shape and size of the display device.
[0064] like Figure 1 As shown, the diffusion plate bracket 23 is located between the back plate 21 and the diffusion plate 25, and is used to support the diffusion plate 25, so as to prevent the diffusion plate from collapsing and affecting the display effect.
[0065] Among them, Figure 3 and Figure 5 As shown, the diffuser plate bracket 23 includes a support sheet 231 ; the plane where the support sheet 231 is located is parallel to the extension direction of the light bar 22 .
[0066] The embodiment of the utility model can improve the problem of obvious shadows of the diffuser plate bracket in the backlight module and avoid the generation of dark bands by arranging the plane where the support plate in the diffuser plate bracket is located to be parallel to the extension direction of the light strip, and can further improve the subjective viewing effect and avoid the use of thicker optical films or more expensive optical films for shielding, thereby reducing production costs.
[0067] Figure 6 One of the structural schematic diagrams of the diffusion plate bracket provided in the embodiment of the utility model, Figure 7 The second structural diagram of the diffusion plate bracket provided by the embodiment of the utility model is as follows: Figure 8 The third structural diagram of the diffuser plate bracket provided in the embodiment of the utility model is as follows: Fig. 9 This is a fourth structural schematic diagram of the diffuser plate bracket provided in an embodiment of the utility model.
[0068] In some embodiments, Figures 6 to 9As shown, the diffuser bracket 23 further includes: a base 232 and an elastic member 233; the base 232 is fixed on the back plate 21, the elastic member 233 is located on the side of the base 232 away from the back plate 21, and the support sheet 231 is fixed on the elastic member 233. The elastic member can buffer the external force on the diffuser in the height direction, thereby preventing the diffuser bracket from causing damage to the diffuser.
[0069] In some embodiments, Fig. 9 As shown, the elastic member 233 includes a first portion 2331, a second portion 2332 and a third portion 2333 which are interconnected, and the second portion 2332 is located between the first portion 2331 and the third portion 2333; the first portion 2331 and the third portion 2333 are symmetrically arranged about the second portion 2332; the width of the second portion 2332 along the first direction F1 is greater than the width of the first portion 2331 along the first direction F1, and the width of the second portion 2332 along the first direction F1 is greater than the width of the third portion 2333 along the first direction F1; and the support sheet is fixed on the second portion.
[0070] Among them, the first part and the third part are symmetrically arranged with respect to the second part, ensuring that the second part is in the center position, that is, ensuring that the support plate is in the center position, so that the elastic part can evenly buffer the external force exerted on the support plate in the height direction and avoid uneven force on the elastic part.
[0071] Furthermore, by making the width of the second portion along the first direction greater than the widths of the first portion and the third portion along the first direction, it is possible to ensure that the support sheet is more stably fixed on the second portion.
[0072] In some embodiments, Fig. 9 As shown, the width of the support sheet 231 along the first direction F1 is the same as the width of the second portion 2332 along the first direction F1. This ensures that the second portion can stably support the support sheet while not consuming too much material when making the elastic member, further saving costs.
[0073] In some embodiments, Fig. 9 As shown, the base 232 includes at least two positioning holes 2320, and the base 232 is fixed to the back plate 21 through the fixing member penetrating the positioning holes 2320; the positioning holes 2320 are arranged at intervals along the first direction F1, and the elastic member 233 is located between the two positioning holes 2320. This arrangement can facilitate the subsequent installation of the diffuser bracket, facilitate the positioning of the diffuser bracket, and ensure that the support sheet is located at the center of the entire diffuser bracket, so that the entire diffuser bracket can be evenly stressed.
[0074] Exemplarily, the fixing member may include a structure that can be fixed, such as a screw, which is not specifically limited here.
[0075] In some embodiments, the overall height of the diffuser plate bracket 23 is not greater than 27 mm, and the thickness of the support sheet 231 is not greater than 0.5 mm. Among them, by controlling the overall height of the diffuser plate bracket, the OD (light mixing distance) value between the backlight source and the diffuser plate can be improved, that is, the thickness of the entire backlight module can be reduced, thereby saving the packaging material cost during transportation; and by controlling the thickness of the support sheet, that is, by thinning the support sheet, the problem of obvious shadows of the diffuser plate bracket can be further improved, thereby achieving a better optical experience effect, that is, improving the subjective viewing effect; and by reducing the overall height of the diffuser plate bracket, the overall support strength of the diffuser plate bracket can be guaranteed, avoiding insufficient support strength due to excessive height, thereby easily being damaged.
[0076] In some embodiments, the diffuser plate bracket is made of a transparent material or a translucent material. This arrangement can further improve the problem of obvious shadows of the diffuser plate bracket, avoid the appearance of dark bands, and thus achieve a better optical experience effect, that is, improve the subjective viewing effect.
[0077] In some embodiments, the diffuser plate bracket may be an integrally formed structure, which is convenient and fast to manufacture and saves costs.
[0078] In some embodiments, Figure 2 and Figure 3 As shown, the backlight module 2 includes a light bar 22, and the diffusion plate bracket 23 is respectively located on both sides of the light bar 22 along the second direction F2, and the first direction F1 is perpendicular to the second direction F2. This arrangement can prevent the diffusion plate bracket from affecting the adjacent light-emitting devices for mixing light, minimize the shadow of the diffusion plate bracket, and reduce the probability of dark bands, thereby achieving a better optical experience effect, that is, improving the subjective viewing effect.
[0079] In some embodiments, the backlight module 2 includes at least two light bars 22, which are parallel to each other and arranged in sequence along the second direction F2; the first direction F1 is perpendicular to the second direction F2; such an arrangement can ensure uniform light emission from the entire backlight module.
[0080] The diffuser brackets 23 are all located at the center of four adjacent light emitting devices 222 along the first direction F1 and the second direction F2; the diffuser brackets 23 are arranged at intervals along the first direction F1. This arrangement can minimize the shadow of the diffuser bracket and reduce the probability of dark bands, thereby achieving a better optical experience effect, that is, improving the subjective viewing effect.
[0081] In some embodiments, Figure 1 As shown, the backlight module 2 further includes: a reflective sheet 24, which is located on the side of the light bar 22 away from the back plate 21; the reflective sheet 24 is used to reflect the light emitted by the light emitting device 222 toward the light emitting side, thereby improving the utilization rate of the light.
[0082] For example, Figure 1 As shown, after the light emitted by the light emitting device 222 reaches the position where the diffuser plate 25 is located, part of the light is refracted by the diffuser plate 25 and continues to move in the direction of the emitted light, and the other part of the light is reflected by the surface of the diffuser plate 25 at the diffuser plate 25 and then enters the surface of the reflective sheet 24. The reflective sheet 24 reflects this part of the light and re-emits it in the direction of the diffuser plate 25. After repeated reflection and refraction, the utilization rate of the light can be improved and the light mixing can be made more uniform.
[0083] Fig.10 The third schematic diagram of the top view structure of the display device provided by the embodiment of the utility model is as follows: Fig.11 This is a fourth schematic diagram of the top view structure of the display device provided in an embodiment of the utility model.
[0084] In some embodiments, Fig.10 and Fig.11 As shown, the reflective sheet 24 includes a plurality of first through holes 241 and a plurality of second through holes 242 .
[0085] The plurality of first through holes 241 correspond to the light emitting devices 222 one by one, and the light emitting devices 222 are exposed from the corresponding first through holes 241 .
[0086] The first through hole is circular so that the reflector can adapt to the light emitting device. The distance between the edge of the first through hole and the corresponding light emitting device is at least greater than 1.5 mm to avoid position errors of the light emitting device, which may lead to unsuccessful installation of the reflector.
[0087] The second through holes 242 correspond to the diffuser plate brackets 23 one by one, and the support sheets and elastic members of the diffuser plate brackets 23 are exposed from the corresponding second through holes 242 .
[0088] The second through hole is in a strip shape as a whole, and the width of the second through hole in the middle is greater than the width at both ends, so that the support sheet and the resilient member of the diffuser bracket can be exposed. The distance between the edge of the second through hole and the corresponding diffuser bracket is at least greater than 1.5 mm, so as to avoid errors in the position of the diffuser bracket, which may lead to unsuccessful installation of the reflector.
[0089] In some embodiments, Figure 1 As shown, the optical film 26 is located between the display panel 1 and the diffusion plate 25. The arrangement of the optical film 26 can make the backlight module 2 adapt to various practical applications.
[0090] Exemplarily, the optical film 26 is located on the side of the diffuser 25 away from the back plate 21. The optical film 26 can be provided as a whole layer, and its shape is the same as the overall shape of the diffuser 25, and can usually be provided as a rectangle or a square. When applied to a special-shaped display device, its shape and size are adapted to the shape and size of the display device.
[0091] Exemplarily, the optical film 26 may include one or a combination of a fluorescent film, a prism film, a brightness enhancement film, etc., and may be configured according to specific needs, which is not limited herein.
[0092] Exemplarily, the optical film 26 may be fixed to the diffuser plate 25 by means of double-sided adhesive tape. Of course, the optical film 26 may also be fixed to the diffuser plate 25 by means of other fixing methods, which are not limited herein.

[0094] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
