[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.

[0017] Figure 1 This is a schematic diagram of the structure of the light guide component in one embodiment of the present invention; Figure 2 for Figure 1 Another structural diagram of the light guide component in the diagram; Figure 3 for Figure 1 A cross-sectional view of the light guide component in the image. Detailed Implementation

[0018] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Figure 1 , Figure 2 and Figure 3 As shown, a light guide assembly 10 includes: an upper light guide lens 100 and a lower light guide lens 200, the upper light guide lens 100 and the lower light guide lens 200 being connected, and the upper light guide lens 100 and the lower light guide lens 200 being respectively filled with a light-transmitting and diffusing mixture 300; the upper lens 100 is provided with a refractive boss 110 and an upper light guide bump group 120, the upper light guide bump group 120 including a plurality of upper light guide bumps 121, each upper light guide bump 121 being disposed around the refractive boss 110; the lower lens 200 is provided with a lower light guide bump group 210, the lower light guide bump group 210 including a plurality of lower light guide bumps 211, each lower light guide bump 211 being disposed in a one-to-one correspondence with each upper light guide bump 121.

[0019] It should be noted that the light guide assembly 10 consists of an upper light guide lens 100 and a lower light guide lens 200. The light guide assembly 10 is positioned at the light source of the display screen, thereby enabling light guidance and diffusion of the light source. Since the upper light guide lens 100 and the lower light guide lens 200 are respectively filled with a light-transmitting diffusion mixture 300, the overall light-transmitting diffusion performance and the purity of the emitted color can be improved, thus improving the overall product quality and reducing the complexity of the manufacturing process, thereby increasing production efficiency. In this embodiment, the light-transmitting diffusion mixture is a mixture of quantum dots and a diffusing agent. The upper light guide lens 100 and the lower light guide lens 200 can be injection molded from PMMA material. In actual production processes, PMMA material, quantum dots, and a diffusing agent are used for injection molding to obtain the upper light guide lens 100 and the lower light guide lens 200 containing the light-transmitting diffusion mixture 300. This not only improves the light guiding performance of the light guide assembly 10 but also increases the overall production efficiency. Furthermore, in actual production and processing, the upper light guide lens 100 and the lower light guide lens 200 are integrally molded structures. In this way, the upper light guide lens 100 and the lower light guide lens 200 can be interconnected in one injection molding process, thereby improving the efficiency of production and processing and improving the overall processing strength.

[0020] Furthermore, the upper lens 100 is provided with a refractive protrusion 110 and multiple upper light guide protrusions 121, and the lower lens 200 is provided with multiple lower light guide protrusions 211 at positions corresponding to the upper light guide protrusions 121. Thus, when light from the display screen enters through the lower lens 200, it is refracted by the refractive protrusion 110, and then guided by the lower light guide protrusions 211 and the upper light guide protrusions 121, thereby achieving light guiding processing of the light source within the display screen. The light guide assembly 10 of this invention, by filling the upper light guide lens 100 and the lower light guide lens 200 with a light-transmitting and diffusing mixture 300, can improve the overall light transmission and diffusion performance and the purity of the emitted color, thereby improving the overall product quality. Simultaneously, it can reduce the complexity of the manufacturing process, thus increasing production efficiency.

[0021] Combination Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the surface of the upper light guide lens 100 is provided with upper support pillars 130. Two upper support pillars 130 are provided, and the two upper support pillars 130 are arranged opposite each other. Thus, the light guide assembly 10 can be installed at the corresponding position on the display screen via the upper support pillars 130, and this prevents the surface of the upper light guide lens 100 from being scratched, thereby improving the overall product quality. Similarly, the surface of the lower light guide lens 200 is provided with lower support pillars 220. Two lower support pillars 220 are provided, and the two lower support pillars 220 are arranged opposite each other. The lower support column 220 allows the light guide assembly 10 to be installed at the corresponding position on the display screen, preventing scratches on the surface of the lower light guide lens 200 and thus improving the overall product quality. Similarly, the upper light guide bump has an arc-shaped bump structure, and multiple upper light guide bump groups are provided, thereby improving the overall light guiding efficiency and range, and thus improving the overall product quality. Likewise, the lower light guide bump has an arc-shaped bump structure, and multiple lower light guide bump groups are provided, thereby improving the overall light guiding efficiency and range, and thus improving the overall product quality.

[0022] In one embodiment, a display module includes the light guide component 10 and a display screen. The light guide component 10 is disposed inside the display screen. Thus, by placing the light guide component 10 at the light source position of the display screen, light guiding operation can be performed on the display screen, thereby improving the overall light guiding quality.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
