[0036] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described below in conjunction with the drawings and embodiments. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments described herein; on the contrary, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus the repeated description thereof will be omitted. The words expressing positions and directions described in the present invention are all illustrated with reference to the drawings, but can be changed according to needs, and all the changes made are included in the protection scope of the present invention. The drawings of the present invention are only used to illustrate the relative positional relationship and do not represent the actual proportion.

[0037] Based on this, the present invention provides a display device, in combination with Figure 1 and Figure 2 as shown, the display device includes a display panel 10 and a backlight module 20; the display panel 10 is used for image display, and the backlight module 20 is disposed on the light-incident side of the display panel 10 and is used to provide backlight for the display panel 10.

[0038] Specifically, taking the surface on which the display panel 10 presents an image as the front, the light-incident side of the display panel where the backlight module 20 is disposed is the back of the display panel 10. In this way, the light emitted by the backlight module 20 is on the back of the display panel 10 to provide backlight for the display panel 10, enabling the display panel 10 to display images normally.

[0039] The backlight module 20 includes a back plate 200, a light-emitting substrate, and a plurality of optical elements; the plurality of optical elements include a reflective sheet, a diffusion plate, and so on.

[0040] The light-emitting substrate includes a plurality of light-emitting devices; the plurality of light-emitting devices emit light to provide backlight for the display panel. The light-emitting substrate is disposed on the back plate 200.

[0041] The reflective sheet can reflect the light incident on the back plate so that the light is directed towards the display panel 10, thereby improving the light utilization rate.

[0042] The diffusion plate reflects, refracts, scatters, etc. the light, and can evenly distribute the light to the entire display panel 10. Therefore, its advantage lies in being able to improve the brightness and color sensitivity of the display panel 10.

[0043] Currently, the backlight module also includes a rubber frame assembly, and the rubber frame assembly is used to fix a plurality of optical elements. Thus, the display device includes a rubber frame assembly, a plurality of optical elements, a backplane, a light-emitting substrate, and a display panel. There are many components, and the manufacturing is rather cumbersome, reducing the manufacturing efficiency.

[0044] Based on this, the present utility model improves the backplane, and in combination with Figure 1 As shown, both sides of the backplane 200 include a first bending structure 200-1; the first bending structure 200-1 forms a receiving groove 200-5, and the edge of the display panel 10 is installed on the first bending structure 200-1 and is not within the receiving groove 200-5 of the first bending structure 200-1 on both sides of the backplane 200.

[0045] During the actual use process, the display device is set upright, and the first bending structures 200-1 on the left and right sides of the backplane do not play a major role in connecting the edge of the display panel to prevent the display panel from falling off. Therefore, in the present utility model, the reinforcement of the connection between the first bending structure and the display panel is not considered on the left and right sides of the backplane. Instead, considering that the side of the display panel will also be damaged, in order to alleviate this situation, both sides of the backplane 200, that is, both the left and right sides of the backplane, further include an extension structure 200-2; the extension structure 200-2 is a structure extending from the first bending structure 200-1 towards the display panel 10, and is used to protect the side of the display panel 10; the extension structure 200-2 is in the shape of a panel, and the panel shape blocks the side of the display panel, thereby alleviating the problem that the side of the display panel 10 is damaged.

[0046] In combination with Figure 2 As shown, the top side of the backplane 200 includes a second bending structure 200-3; the second bending structure 200-3 forms a receiving groove 200-5; the edge of the display panel 10 is installed on the second bending structure 200-3 and is not within the receiving groove 200-5 of the second bending structure 200-3.

[0047] For the top side of the backplane, since the second bending structure 200-3 on the top side of the backplane connects the edge of the display panel and plays a major role in preventing the display panel from falling off, in order to prevent the display panel 10 from falling off from the bending structure on the top side of the backplane, a fixing frame 200-4 is further included on the top side of the backplane. The fixing frame 200-4 wraps the second bending structure 200-3 and the edge of the display panel 10, and is used to reinforce the connection between the display panel 10 and the backplane 200, so as to prevent the display panel from falling off from the bending structure on the top side of the backplane.

[0048] The details of the multiple optical components in the backlight module are as follows:

[0049] Combination Figure 1 and Figure 3 As shown, the diffuser 203 is opposite to the middle area of ​​the back plate 200 and is separated by a set distance; the left and right sides of the diffuser 203 are inserted into the receiving grooves 200-5 of the first bending structures 200-1 on both sides of the back plate. The left and right sides of the display panel 10 are arranged on the first bending structures 200-1 on both sides of the back plate, and are not in the receiving grooves 200-5.

[0050] Combination Figure 2 and Figure 4 As shown, the upper side of the diffusion plate 203 is inserted into the receiving groove 200-5 of the second bending structure 200-3 on the upper side of the back plate. The upper side of the display panel 10 is arranged on the second bending structure 200-3 on the upper side of the back plate and is not in the receiving groove 200-5.

[0051] Among them, the back panel 200 can be convex, with the protruding opening facing the display panel. When the edge of the diffuser plate 203 is installed in the accommodating groove, the diffuser plate 203 has a certain distance from the back panel. In order to make the diffuser plate 203 more firm, a diffuser plate bracket is arranged between the diffuser plate and the back panel, and the diffuser plate bracket is used to support the diffuser plate.

[0052] Combination Figure 5 As shown, the light-emitting substrate is in the shape of a plate and is attached to the back panel. The reflective sheet 202 reflects light and is located on the side of the light-emitting substrate 201 away from the back panel 200. The reflective sheet 202 includes a plurality of light-through holes 2021 and a plurality of mounting holes 2022. The light-through holes 2021 are used to expose the light-emitting device 2011, and the mounting holes 2022 are used to install the diffuser plate bracket. The area of ​​the reflective sheet 202 having the plurality of light-through holes 2021 and the plurality of mounting holes 2022 is attached to the light-emitting substrate 201, and the other areas of the reflective sheet 202 are attached to the back panel 200.

[0053] The utility model can set bending structures on both sides and the sky side of the back plate, the edge of the display panel is installed on the bending structure, the bending structure forms a receiving groove, the receiving groove of the bending structure can place the edge of the diffusion plate in the backlight module, so that the diffusion plate is fixed, the connection between the bending structure on the sky side and the display panel is fixed by a fixing frame to prevent the display panel from falling off, and the two sides of the back plate also include extension structures, the extension structure protects the side of the display panel, thus using the back plate to replace the rubber frame assembly to fix the optical element, saving the steps of making the rubber frame assembly, and improving the production efficiency, and the extension structure and the fixing frame of the back plate protect the display panel.

[0054] In some embodiments, in combination Figure 3As shown, the first bending structure 200-1 on the left and right sides of the backplane includes a first side surface 1-a, a second side surface 1-b, and a first bottom surface 1-c; the first side surface 1-a and the second side surface 1-b are located on both sides of the first bottom surface 1-c and are connected to the first bottom surface 1-c; the first side surface 1-a and the second side surface 1-b are parallel to each other. Among them, the extension structure 200-2 on the left and right sides of the backplane is an extension part of the first bottom surface 1-c.

[0055] On the left and right sides of the backplane of the present utility model, an F-bending form is formed. Combining Figure 6 As shown, the vertical line "|" of the "F" is the first bottom surface 1-c and the extension structure 200-2, the uppermost "-" in the "F" is the first side surface 1-a, which is fixed to the diffusion plate, and the other "-" is the second side surface 1-b, which is fixed to the edge of the display panel. This not only fixes and protects the display panel but also makes it more beautiful.

[0056] Combining Figure 4 As shown, the second bending structure 200-3 on the top side of the backplane includes a first side surface 1-a, a second side surface 1-b, and a first bottom surface 1-c. Similarly, the first side surface 1-a and the second side surface 1-b are located on both sides of the first bottom surface 1-c and are connected to the first bottom surface 1-c; the first side surface 1-a and the second side surface 1-b are parallel to each other.

[0057] The edge of the display panel 10 is fixed to the second side surface 1-b of the first bending structure 200-1 on the left and right sides of the backplane and the second side surface 1-b of the second bending structure 200-3 on the top side of the backplane.

[0058] The edge of the diffusion plate 203 is fixed to the first side surface 1-a of the first bending structure 200-1 on the left and right sides of the backplane and the first side surface 1-a of the second bending structure 200-3 on the top side of the backplane.

[0059] In the present utility model, a C-bending form is formed on the top side of the backplane. Combining Figure 6 As shown, the vertical line "|" of the "C" is the first bottom surface 1-c, the uppermost "-" in the "C" is the first side surface 1-a, which is fixed to the diffusion plate, and the other "-" is the second side surface 1-b, which is fixed to the edge of the display panel. In this way, the backplane plays the role of fixing the display panel and the diffusion plate.

[0060] Among them, the backplane can be formed by sheet metal stamping. For example, on the left and right sides of the backplane, it is stamped into an "F" shape by sheet metal. On the top side of the backplane, it is stamped into a "C" shape by sheet metal.

[0061] Exemplarily, combining Figure 3 and Figure 4As shown, the display panel 10 is fixed on the second side surfaces 1-b of the first bending structures 200-1 on the left and right sides of the backplane and the second side surfaces 1-b of the second bending structures 200-3 on the top side of the backplane through the adhesive layer 206. The adhesive layer 206 can be bonded with glue or with surface adhesive. Apply surface adhesive on the surfaces outside the grooves of the second side surfaces 1-b of the first bending structures 200-1 on the left and right sides of the backplane and the second side surfaces 1-b of the second bending structures 200-3 on the top side of the backplane, and then attach the edge of the display panel to the surface adhesive, so as to fix the edge of the display panel and the second side surfaces 1-b of the first bending structures 200-1 on the left and right sides of the backplane and the second side surfaces 1-b of the second bending structures 200-3 on the top side of the backplane. Or, apply glue on the surfaces outside the grooves of the second side surfaces 1-b of the first bending structures 200-1 on the left and right sides of the backplane and the second side surfaces 1-b of the second bending structures 200-3 on the top side of the backplane, and then attach the edge of the display panel to the glue.

[0062] Similarly, the diffuser plate is fixed on the first side surfaces of the first bending structures on the left and right sides of the backplane and the first side surfaces of the second bending structures on the top side of the backplane through the adhesive layer. The adhesive layer can be glue or surface adhesive. When fixing, apply the glue or surface adhesive on the surfaces inside the grooves of the first side surfaces of the first bending structures on the left and right sides of the backplane and the first side surfaces of the second bending structures on the top side of the backplane, and then attach the edge of the diffuser plate to the glue or surface adhesive, so as to fix the diffuser plate and the first side surfaces of the first bending structures on the left and right sides of the backplane and the first side surfaces of the second bending structures on the top side of the backplane.

[0063] In some embodiments, the height of the extension structure matches the thickness of the display panel. In this way, when viewed from the side of the display device, the extension structure completely blocks the side of the display panel, which better protects the side of the display panel, thus alleviating the problem of damage to the side of the display panel 10.

[0064] In some embodiments, in combination Figure 4 As shown, the fixing frame 200-4 includes a third side surface 1-d, a fourth side surface 1-e and a second bottom surface 1-f; the third side surface 1-d and the fourth side surface 1-e are located on both sides of the second bottom surface 1-f and are connected to the second bottom surface 1-f; the third side surface 1-d and the fourth side surface 1-e are parallel to each other;

[0068] The third side is fixed to the display panel through an adhesive layer; the fourth side is fixed to the first side of the second bending structure through an adhesive layer; the second bottom surface is fixed to the first bottom surface of the second bending structure through an adhesive layer. Glue or surface glue is applied to the third side, the fourth side, and the second bottom surface, and the third side, the fourth side, and the second bottom surface are buckled onto the top side of the backplane where the display panel is installed.

[0069] Of course, in addition to the adhesive layer, when the third side is fixed to the display panel; the fourth side is fixed to the first side of the second bending structure; and the second bottom surface is fixed to the first bottom surface of the second bending structure, a back lock or side lock mode can also be adopted.

A third notch 302 is included at the edge of the optical film 207; when limiting the optical film in the backlight module, the limiting part 301 is inserted into the third notch 302.

[0074] Combined Figure 8As shown, the ear-hanging structure forms an L shape. The vertical line "|" of the "L" is the ear-hanging bracket, and the "-" in the "L" is the limiting part.
