[0048] As shown Figures 1 to 5 in the figure, the present application provides an installation fixture 100 for installing the display module 200, so as to process the flatness of the edge of the display module 200, reduce the deviation of each component of the display module 200 during the assembly process, and prevent the display effect from being poor due to inconsistent splicing surfaces after the display modules 200 are spliced, ensuring the flatness and consistency of the display module 200 after splicing, and effectively solving the problems of high processing precision requirements and large assembly difficulty caused by the high requirement for the flatness of the display surface of the display screen.

[0049] In an optional embodiment, the display module 200 includes a bottom shell 201, a protection structure 202 and a light board 203. The light board 203 and the protection structure 202 are sequentially installed on the bottom shell 201 and the flatness is processed through the installation fixture 100 to ensure the flatness of the edge of the display module 200, reduce the deviation of each component of the display module 200 during the assembly process, and ensure the display effect of the display module 200 after splicing, and prevent the display effect from being poor due to inconsistent splicing surfaces; at the same time, the whole operation is more convenient, the workload is greatly reduced, and the work efficiency is improved.

After the flatness of the outer edge of the protection structure 202 is processed through the installation fixture 100, it is substantially flush with the bottom shell 201, and the surface flatness between the two can be controlled within the range of ±0.02 mm, so that the protection structure 202 will not affect the display effect of the display screen after the display modules 200 are spliced, thereby being able to maintain a good visual effect. Among them, the thickness of the part of the protection structure 202 extending in the vertical direction of the light board 203 is between 0.01 mm and 0.2 mm, so that seamless splicing can be formed when two adjacent display modules 200 are spliced with each other, to ensure the display effect of the display module 200 after splicing; at the same time, the lamp beads 2031 can be protected, and the display module 200 can be prevented from being damaged due to impact during use or transportation.

[0052] In an alternative embodiment, positioning posts 2012 are provided on the bottom case 201, and positioning holes 2021 are provided on the protection structure 202. The positioning holes 2021 cooperate with the positioning posts 2012 for preliminary pre-positioning when the protection structure 202 is installed on the bottom case 201. Then, the flatness of the outer edges of the bottom case 201 and the protection structure 202 is processed by the installation jig 100, so that the two can be controlled within the same plane, or the flatness of the two is controlled within a small range, such as within ±0.02 mm, to ensure the display effect of the display module 200 after splicing, and the display effect will not be poor due to inconsistent splicing surfaces.

The protection sheet 202a is fixed on the bottom case 201 through the reinforcing ribs 202b to achieve stable fixation between the protection sheet 202a and the bottom case 201. Among them, the reinforcing ribs 202b can not only enhance the strength of the bottom case 201, but also enhance the strength of the protection sheet 202a to prevent the protection sheet 202a from squeezing the lamp beads 2031 during collision or extrusion.

[0054] It should be noted that the reinforcing ribs 202b and the protection sheet 202a can be of an integral structure, or the reinforcing ribs 202b and the protection sheet 202a can be of a split structure and then fixed together by an assembly method, or the protection sheet 202a is fixed on the bottom case 201 through the reinforcing ribs 202b, and the present application does not make any restrictions.

The horizontal section is fixed on the bottom case 201 through the reinforcing ribs 202b, and the vertical section does not exceed the surface of the lamp beads 2031 of the lamp board 203 to protect the lamp beads 2031.

[0057] In an alternative embodiment, the positioning holes 2021 include a first positioning hole 2021a and a second positioning hole 2021b. The first positioning hole 2021a is provided on the horizontal section, and the second positioning hole 2021b is provided on the reinforcing rib 202b, so that both the protective sheet 202a and the reinforcing rib 202b can be preliminarily pre-positioned through the cooperation of the first positioning hole 2021a and the second positioning hole 2021b with the positioning post 2012. Then, the flatness of the outer edges of the bottom shell 201 and the protection structure 202 is processed by the installation jig 100, so that the two can be controlled to be in the same plane, or the flatness of the two is controlled within a small range, such as within ±0.02 mm, to ensure the display effect of the display module 200 after splicing, and the display effect will not be poor due to inconsistent splicing surfaces.

[0058] In an alternative embodiment, fixing holes 2022 are provided on the reinforcing rib 202b, and fixing parts 2013 are provided on the bottom shell 201. The positions of the fixing holes 2022 correspond to the positions of the fixing parts 2013, so that the reinforcing rib 202b can be fixed on the fixing parts 2013 through the fixing holes 2022, so as to realize the fixed connection between the protective sheet 202a, the reinforcing rib 202b and the bottom shell 201.

[0059] In an alternative embodiment, the number of the protective sheets 202a is multiple. The multiple protective sheets 202a are sequentially arranged along the outer edge of the bottom shell 201 and enclose to form an enclosing structure, and the enclosing structure encloses the outside of the lamp beads 2031 of the lamp board 203 to protect the lamp beads 2031.

[0060] In an alternative embodiment, the protective sheet 202a is in an L-shaped structure or a T-shaped structure to enhance the overall strength of the display module 200, and can also prevent the corners of the bottom shell 201 from being damaged when collided, or even cause the deformation of the module bottom shell 201, so that it cannot be used.

[0061] Exemplarily, the number of the protective sheets 202a is four, and the four protective sheets 202a are all in an L-shaped structure. The four protective sheets 202a are respectively arranged at the four corners of the bottom shell 201 to protect the lamp beads 2031 at the corners of the display module 200 and prevent the display module 200 from being damaged by impact during use or transportation. In addition, the protective sheet 202a can also enhance the strength of the bottom shell 201 and prevent the corners of the bottom shell 201 from being damaged when collided, or even cause the deformation of the module bottom shell 201, so that it cannot be used.

[0062] In an optional embodiment, the display module 200 also includes a mask 204, which is arranged on the outside of the lamp beads 2031 of the lamp board 203 and contacts the protective sheet 202a. It can improve the display effect of the display module 200, enhance the contrast of the display screen, and even play a role in waterproofing and dustproofing.
