Description

Technical Field

[0001] The present application relates to the technical field of LED display screens, and in particular to a highly adaptable LED display module and a construction and installation method thereof. Background Art

[0002] As people's living conditions are getting better and better and urbanization is highly developed, super-large and medium-sized cities are constantly emerging, and night lights are gradually becoming one of the manifestations of the prosperity of various cities. The architectural design of urban buildings is becoming more and more diverse, and it is constantly showing more artistry. Most of the surfaces of these uniquely artistic buildings are no longer regular planes, but a variety of curved surface designs, which directly leads to the inability of traditional LED screens to be installed and applied on these emerging architectural designs. In addition, tourism consumption is becoming more and more popular among people, and the tourism industry has therefore achieved unprecedented development and burst into vigorous vitality. In recent years, many tourist destinations have successively launched large-scale live performance projects such as "Thousands of Years of Love" and various light shows. These magnificent performances and performances are inseparable from LED displays. The tourist buildings that have sprung up in various places are also of various shapes, such as spherical, conical, trumpet-shaped and other combinations of special-shaped curved surfaces, etc., which makes it impossible for the transmission LED display screen to be well installed on these buildings and ensure the display effect after installation. It can only be completed by customization and manual fine adjustment. If it is not done, the construction period will be long, the precision control will be difficult, the display effect may be mediocre, and the cost will also be high. Summary of the invention

[0108] In one embodiment, the method further includes: connecting the first telescopic hinges 100 in adjacent LED display modules to each other. Connecting the second telescopic hinges 200 in adjacent LED display modules to each other.

[0109] In one embodiment, the method further includes: fixing the first telescopic hinge 100 on the target building. Fixing the second telescopic hinge 200 on the target building.

[0110] In one embodiment, both ends of the first telescopic hinge 100 are fixed on the target building. Both ends of the second telescopic hinge 200 are fixed on the target building.

[0111] In one of the embodiments, the method further includes: using at least one transverse steel wire rope to pass around a plurality of LED display modules on the mounting surface, and pre-tightening the transverse steel wire rope to bind the LED light strips 300 in the LED display modules to the mounting surface.

[0112] The construction and installation method of the LED display module provided above, by pre-determining the installation point and pre-embedded installation parts, can enable the highly adaptable LED display module in this application to accurately find the installation point and install it directly during installation, and it does not need to be installed sequentially from a certain direction, and can be assembled by multiple installers from multiple directions, and the installation accuracy can be guaranteed. At the same time, this method adopts modular splicing installation during installation, and the LED display module can be more easily hoisted and operated by a single worker, which is simpler and saves time and effort.

[0113] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0114] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
