[0028] Embodiment

[0029] Please refer to Figure 1 and Figure 2 It is provided that the display module comprises a transparent plate body 10; the middle part of the transparent plate body 10 is provided with at least one color picture area 11 and a display area 12, a plurality of light guide grooves 111 are arranged side by side in the color picture area 11, a light shielding layer 13 is arranged on the surface of the transparent plate body 10, and the light shielding layer 13 is provided with a hollow avoiding part 131 between the light guide groove 111 and the adjacent light guide groove 111; a plurality of side light through holes 14 are arranged along the profile edge of the surface of the transparent plate body 10 and are arranged at intervals; a plurality of display through holes 121 are arranged in the display area 12. The color picture area 11 between the light guide groove 111 and the adjacent light guide groove 111 is provided with a light condensing arc surface 112.

[0030] Specifically, the transparent plate body 10 can be an acrylic plate or a glass plate, and through the one-piece plate body design, the refractive index and light transmission rate of the light are ensured. A side light through hole 14 is arranged at the edge of the transparent plate body 10, and after placing a lamp bead in the side light through hole 14, a light source can be provided for irradiating towards the inside; at the same time, in order to avoid the light intensity of the middle part of the transparent plate body 10 being not uniform, the lamp bead is placed in the light guide groove 111 to ensure the brightness of the color picture area 11, so that the purpose of forming a clear display module can be achieved. Furthermore, the transparent plate body 10 has a display area 12, and the display area 12 can form a texture of characters, numerical values or patterns through the arrangement of display through holes 121, such as being arranged in the style of Arabic numerals. By turning on and off the lamp beads in different display through holes 121, different numerical display effects can be formed to achieve the purpose of display. Alternatively, by providing the display area 12, the lamp beads in the display through holes 121 can provide light to ensure the clarity of the display area 12.

[0031] Further, in order to avoid the edges of the transparent plate body 10 from diffusing light, a light shielding layer 13 is arranged on the transparent plate body 10 to shield light, so as to provide good light in the color picture area 11. The light shielding layer 13 can be formed by coating black paint or pasting black tape. The areas that need to be displayed in a transparent manner are designed to be avoided by the hollow avoiding part 131 to form a good display purpose.

[0032] Further, in order to design a light focusing arc surface 112 in the area that needs to be displayed in the color picture area 11, a good light focusing effect can be formed to ensure the light intensity of the area and form a clear light area.

[0033] As shown in the figure, Figure 1 In the embodiment, two color picture areas 11 are arranged symmetrically with the display area 12, so that the area of the color picture area 11 can be increased, and more button areas or operation areas can be designed in the color picture area 11 to adapt to the use of different types of display modules and improve the practicality.

[0034] As shown in the figure, Figure 2 In the embodiment, a light guide ink layer 15 is arranged on the surface of the transparent plate body 10, and the light guide ink layer 15 is arranged between the light shielding layer 13 and the transparent plate body 10. The light guide ink in the light guide ink layer 15 has a good light guide effect. The principle of the light guide ink is to add light guide powder to the ink, use the high refractive index and light scattering characteristics of the light guide powder, and make the light rays in the light guide plate occur diffuse reflection and refraction when propagating in the light guide plate, so as to achieve the purpose of light guide.

[0035] In this embodiment, the thickness of the transparent plate 10 is 1.8mm to 5mm, and the depth of the light guide groove 111 is 1.5mm to 4.5mm. Preferably, the transparent plate 10 is an acrylic plate with a thickness of 2mm, and the depth of the light guide groove 111 is 1.7mm, resulting in a thickness of 0.3mm, which ensures edge light transmission and improves illumination. Furthermore, using side lighting reduces the thickness of the transparent plate 10, allowing for more flexible assembly and improved practicality.

[0036] like Figure 1 As shown, in this embodiment, the transparent plate 10 is provided with a number of locking holes 16, which can be used for locking or plugging assembly, so as to achieve a stable and quick installation.

[0037] like Figure 1 As shown, in this embodiment, a power receiving part 17 is provided on one end of the transparent plate 10, and a power supply part 18 is provided on the other end of the transparent plate 10. The power receiving part 17 has a groove or through hole to accommodate a conductive sheet, so as to make an electrical connection through the transparent plate 10, thereby forming a power connection effect. Similarly, the power supply part 18 also has a groove or through hole to accommodate a conductive sheet, thereby forming a circuit connection effect.

[0038] In this embodiment, the color picture area 11 is provided with multiple square pressing parts and / or strip pressing parts. The light guide groove 111 is used for segmentation design to ensure the light intensity or clarity of each square pressing part and / or strip pressing part, so that it can be operated after the button is installed.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
