Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In the description of the present invention, unless otherwise specified, “plurality” means two or more. Example 1

[0039] Reference Figure 1 As shown, a display device includes:

[0040] a housing, forming an installation space therein;

[0041] A lighting lamp assembly 300, which is fixed in the installation space, and the lighting lamp assembly 300 includes a plurality of lamp beads 311 distributed in an array;

[0042] A light-distributing member 200, which is covered on the periphery of the lighting lamp assembly 300 and is located in the installation space;

[0043] PCB500 board, which is electrically connected to the lighting lamp assembly 300;

[0044] The housing includes a display portion 121 and an assembly portion 122 . The display portion 121 is provided with an arc-shaped surface, and the assembly portion 122 is fixedly connected to an external product.

[0045] In this embodiment, the surface of the shell can be set to be curved, which will not affect the display effect displayed by the light homogenizing member 200 as a screen, and can also meet the user's needs for different shapes and colors of the appearance of the display device.

[0046] In some embodiments of the present invention, in order to enhance the display effect of the shell, at least the display portion 121 is made of a transparent base material. Specifically, the display portion 121 in the shell is transparent, thereby enhancing the display effect of the light homogenizing member 200 as a screen.

[0047] That is to say, the material of the display part 121 is a transparent material or a basic cost including a transparent material substrate and a color powder to realize the color of the display part 121; in addition, for the assembly part 122, because it is used to be fixedly connected with an external product, the fixing method of the two is generally that the assembly part 122 is plugged or snapped into the external product, and the display part 121 only needs to be exposed to the external product, so the assembly part 122 can be a transparent material or an ordinary material without a transparent effect.

[0048] Specifically, for the structure of the housing, continue to refer to Figure 1 As shown, the shell includes an upper shell 110 and a lower shell 120, wherein the lower shell 120 is divided into a display part 121 and an assembly part 122. In this embodiment, the display part 121 is surrounded by an arc-shaped side panel 420, and its top end is fixed to the upper shell 110. The fixing method of the two can be snap-fitting or bonding, etc., and the upper shell 110 also presents an arc-shaped surface protruding upward.

[0049] Furthermore, a first installation space is formed in the display portion 121, which forms a sealed first installation space with the upper shell 110, wherein the lighting lamp group 300 and the light uniformizing element 200 are located in the first installation space, and both are opposite to the curved side panel 420 of the display portion 121. Since the display portion 121 is made of transparent material, it will not have a negative impact on the display effect of the light uniformizing element 200.

[0050] In some embodiments of the utility model, in order to match the installation space of the external product, the assembly portion 122 can be set to a barrel-shaped structure. Specifically, a second installation space is formed in the assembly portion 122, and the PCB500 is located in the second installation space; the barrel-shaped structure can not only adapt to the plate structure of the PCB500, but also does not occupy a large installation space, and is convenient for realizing various fixed connection methods between the shell and the external product.

[0051] In some embodiments of the present invention, the clarity of the display device is an important evaluation parameter, so in order to improve the clarity of the display device, the distance between the light-distributing member 200 and the lighting lamp group 300 is designed in this embodiment. Specifically, the distance between the light-distributing member 200 and the lighting lamp group 300 is not greater than twice the distance between the adjacent lamp beads 311, so as to ensure the clarity of the display effect of the light-distributing member 200.

[0052] That is, since a plurality of lamp beads 311 are evenly distributed on the lamp board 310, the plurality of lamp beads 311 form a light-emitting surface, and the distance between the light-distributing member 200 and the light-emitting surface is adjusted according to the distance between adjacent lamp beads 311. Figure 3-Figure 5 As shown, the distance between the light-distributing member 200 and the light-emitting surface is defined as y, and the distance between two adjacent lamp beads 311 is defined as x. In this embodiment, y≤2x. After testing, when y=2x, the granularity of the light source of the display device is completely invisible, the whole is very uniform, and the display effect is better.

[0053] In addition, in other embodiments of the present invention, the distance between the light-homogenizing member 200 and the lamp board 310 is not less than half of the distance between adjacent lamp beads 311 , that is, 0.5x≤y; according to experiments, when y=0.5x, the display effect is clear.

[0054] In some embodiments of the present invention, the spacing between the light-distributing element 200 and the lamp board 310 is equal to the spacing between the adjacent lamp beads 311, that is, y=x, and the granularity of the light source of the display device is close to zero, and the clarity is also high. In other words, not only the display effect of the light-distributing element 200 is improved, but also the granularity of the light source is avoided.

[0055] In order to realize the function of the light-homogenizing sheet as a screen, it uses a diffusion material or a transparent material with a frosted surface treatment to achieve the effect of light mixing.

[0056] In some embodiments of the utility model, the lighting lamp group 300 also includes a lamp board 310, a first connecting part 320 and a second connecting part 330; the lamp board 310 is an annular structure, and the lamp beads 311 are fixed on the lamp board 310; the first connecting part 320 is fixedly connected to the lamp board 310; the second connecting part 330 is intersected with the first connecting part 320 and fixedly connected.

[0057] Specifically, in order to increase the connection stability of the lighting lamp set 300, the cross section of the lamp board 310 is a polygonal structure, that is, a vertical plate structure surrounded by a polygonal ring structure, and a plurality of lamp beads 311 are evenly arranged on the lamp board 310. The lamp board 310 can be a hard lamp board 310 or other materials such as FPC. Among them, the lamp beads 311 are LED lamp beads 311, which are used as light sources and can be densely arranged on the lamp board 310 as needed.

[0058] In some embodiments of the present invention, referring to Figure 3 As shown, the light evenly distributed member 200 includes a light evenly distributed portion 210 and a fixing portion 220 . The structure of the light evenly distributed portion 210 is compatible with the structure of the light board 310 . The fixing portion 220 is located at the top of the light evenly distributed portion 210 . A plurality of fixing holes 221 are provided on the fixing portion 220 .

[0059] Specifically, the light-evening portion 210 is located at the periphery of the lamp board 310, corresponding one-to-one to each vertical plate structure of the lamp board 310, and the light-evening portion 210 is sleeved on the outside of the lamp board 310 and is equidistant from all locations of the lamp board 310, that is, the two are parallel in the axial direction.

[0060] In order to increase the connection stability between the light-distributing sheet and the light board 310 and avoid horizontal displacement between the two, a bending structure is provided at the top of the light-distributing portion 210, and the bending structure is clamped on the light board 310, and the fixing portion 220 is fixedly connected to the bending structure. In addition, the connection point between the fixing portion 220 and the bending structure is located at the vertex of a triangle, that is, the fixing portion 220 is composed of three integrally formed support plates, one end of each support plate intersects at a point, and the other end is fixedly connected to the bending structure, thereby realizing the connection between the fixing portion 220 and the light-distributing portion 210.

[0061] At the same time, in order to use other fixing parts to connect the light-distributing plate and the light board 310, each support plate is provided with a fixing hole 221, and the fixing hole 221 can cooperate with the fixing part to fix the light-distributing plate and the light board 310.

[0063] Specifically, refer to Figure 6 As shown, the mounting member 400 includes a top plate 410 and a side plate 420 , and a plurality of protrusion structures are provided on the side plate 420 , and the protrusion structures are fixedly connected to the assembly portion 122 , thereby achieving fixation of the mounting member 400 to the shell, and the lamp panel 310 and the light-distributing plate are located on the top plate 410 of the mounting member 400 .

[0064] In some embodiments of the present invention, the mounting member 400 is provided with a plurality of mounting through holes 430 , the positions of the mounting through holes 430 correspond to the positions of the fixing holes 221 , and the first connecting portion 320 is provided with an avoidance structure corresponding to the positions of the fixing holes 221 .

[0065] Specifically, the mounting through holes 430 are located on the top plate 410 . Since the fixing portion 220 of the light homogenizer is composed of three support plates, there are also three mounting through holes 430 on the top plate 410 , and their positions correspond one-to-one to the mounting holes on the fixing portion 220 .

[0066] Similarly, the light board 310 is located between the fixing portion 220 and the top. In order to provide installation space, an escape space is provided on the first connecting portion 320. Figure 2 As shown, the avoidance space is located at the edge of the first connection portion 320 and is arranged near the connection between the first connection portion 320 and the light board 310 .

[0067] In some embodiments of the present invention, a strip-shaped through hole 440 is further provided on the top plate 410 of the mounting member 400 , and the strip-shaped through hole 440 is used to provide a connection space between the PCB 500 and the lighting lamp assembly 300 .

[0068] During the assembly process of the utility model, the lighting lamp group 300 is covered on the periphery of the mounting member 400, and the avoidance space on the lamp board 310 corresponds to the mounting through hole 430 on the top plate 410; the light-distributing sheet is covered on the periphery of the lighting lamp group 300, and the fixing hole 221 on the fixing part 220 thereof corresponds to the mounting through hole 430 on the mounting member 400, and then the three are placed in the lower shell 120 at the same time, and the strip through hole 440 in the mounting member 400 is aligned with the PCB 500, and the three are fixedly connected to the lower shell 120 by the fixing member.
