[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, a low-reflective LED display screen module described in one embodiment of the present invention includes multiple light-emitting components 1, and the light-emitting components 1 include several light-emitting units. A shading member 201 is provided above each light-emitting group, and the distance between the light-shading member 201 and the nearest light-emitting unit is L. The height of the light-shading member 201 extending in the irradiation direction of the light-emitting component 1 is H, and H / L ≥ 5.6.

[0026] In this embodiment, by controlling the size ratio of the light shielding piece 201, i.e. H / L≥5.6, the light shielding piece 201 can effectively block the light from the range of 10.125°-90° above the horizontal plane, which is the main angle range of sunlight reflection to the human eye. Even in the case of extremely strong sunlight, the light shielding piece 201 can effectively prevent the light from directly incident on the chip of the light-emitting unit, thereby avoiding the problem of strong reflection caused by chip reflection, improving the visibility of the display screen, reducing the visual interference to the driver, enhancing the safety of traffic indication and information transmission, and at the same time ensuring that the light-emitting assembly 1 can fully emit light under normal working conditions, maintaining the original brightness and color performance, and not affecting the basic functions of the traffic signal, road sign or advertising board.

[0027] As shown in Figure 2 In a preferred example, an inclined surface 204 is arranged above the extended end of the light shielding piece 201 to increase the exit angle of the light, so that the light of the light-emitting assembly 1 can normally exit, thereby ensuring the information display effect of the display screen.

[0028] As shown in Figure 2 In a preferred example, the light-emitting assembly 1 includes three light-emitting units, which are red light beads 101, green light beads 102 and blue light beads 103, respectively.

[0029] The three light-emitting units of the light-emitting assembly 1 are arranged in an inverted equilateral triangle shape. The three light beads are closely arranged, and the inverted triangle makes two light beads close to the light shielding piece 201, so that the anti-reflection effect is better.

[0030] The red light beads 101 are located at the lowermost position. The red light beads 101 have relatively low reflection intensity, and the blue light beads 103 and the green light beads 102 have relatively high reflection intensity. Therefore, the blue light beads 103 and the green light beads 102 are closer to the light shielding piece 201, and the anti-reflection effect is better.

[0031] In this embodiment, the red, green, and blue lamp beads 101, 102, and 103 are arranged in an inverted equilateral triangle. This allows the individual lamp beads to be closely spaced, which can improve the pixel density and clarity of the display screen. At the same time, this layout allows two of the lamp beads to be close to the light shield 201, so that more lamp beads are protected from glare by the light shield 201, thereby more effectively utilizing the shading effect of the light shield 201. Secondly, the red lamp bead 101 is placed at the bottom of the inverted equilateral triangle. Compared with the blue and green lamp beads 103 and 102, the red lamp bead 101 generally has a lower reflective intensity. Therefore, placing the red lamp bead 101 relatively far away from the light shield 201 will neither significantly reduce its luminous effect nor significantly increase the risk of glare. In contrast, the blue and green lamp beads 102, due to their higher reflective intensity, are placed close to the light shield 201, thereby obtaining better anti-glare protection.

[0032] like Figure 2 As shown, in a preferred embodiment, a plurality of light emitting components 1 are arranged in an array.

[0033] In this embodiment, the array arrangement of the plurality of light emitting components 1 makes the spacing between the pixels uniform, which helps to improve the resolution and clarity of the display screen.

Meanwhile, the second connecting hole 301 on the circuit board 3 is aligned with the first connecting hole 402 on the bottom shell 4, the first fastener (such as a screw) passes through the second connecting hole 301 and is screwed with the first connecting hole 402, so as to firmly fix the circuit board 3 on the bottom shell 4.

[0038] In the embodiment, the circuit board 3 is connected to the bottom shell 4 by the first fastener, so that the circuit board 3 is firmly connected to the bottom shell 4, the loosening and deviation of the circuit board 3 during use are prevented, and the stability and reliability of the entire display screen module are improved. In addition, the accommodating groove 401 of the bottom shell 4 provides a good heat dissipation environment for the circuit board 3, which helps to prolong the service life of the circuit board 3 and the LED display screen.

[0041] In assembly, the panel 2 is covered above the circuit board 3, the light emitting assembly 1 passes through the through hole 202 so as to normally emit light. Meanwhile, the fourth connecting hole 203 on the panel 2 is aligned with the third connecting hole 404 on the positioning column 403, the second fastener (such as a screw) passes through the fourth connecting hole 203 and is screwed with the third connecting hole 404, so as to firmly fix the panel 2 on the bottom shell 4, and meanwhile, the relative position between the light shielding member 201 and the light emitting assembly 1 is ensured to be stable.

[0042] In the embodiment, the panel 2 and the bottom shell 4 are connected by the second fastener, so that the panel 2 and the bottom shell 4 are firmly connected, and meanwhile, the relative position between the light shielding member 201 and the light emitting assembly 1 is stable, which effectively prevents external light from being incident on the light emitting unit and ensures the anti-reflection performance of the display screen.

[0043] As shown in Figure 2 In a preferred example, the back of the bottom shell 4 is provided with the sliding groove 405, the sliding rail 5 is slidingly arranged in the sliding groove 405, the sliding rail 5 is provided with the limiting column 501 and the fifth connecting hole 502. The sliding rail 5 is used to be installed to a preset fixed position, and the limiting column 501 and the fifth connecting hole 502 are arranged in a staggered manner along the length direction of the sliding rail 5.

[0044] When installing the display screen, the slide rail 5 is installed to the preset fixed position, the limiting column 501 on the slide rail 5 is clamped with the limiting hole on the preset fixed position, the accuracy of the slide rail 5 in the installation process is ensured, then the screw is threaded through the preset fixed position and is screwed with the fifth connecting hole 502 on the slide rail 5, so that the slide rail 5 is firmly fixed on the preset position. After the fixing of the slide rail 5 is completed, the bottom shell 4 can be slidably installed on the slide rail 5 through the slide groove 405 on the back of the bottom shell 4.

[0045] In the embodiment, the slide groove 405 and the slide rail 5 are arranged, so that the bottom shell 4 can be conveniently slidably installed on the preset position, while the stability and the accuracy of the installation are maintained. Secondly, the clamping of the limiting column 501 and the limiting hole and the screwing of the screw and the fifth connecting hole 502 together ensure the firmness of the slide rail 5 on the preset fixed position, so that the bottom shell 4 is prevented from shaking or shifting during use.
