Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and particularly relates to a lightweight double-sided LED display screen structure framework. Background Technique

[0002] As a key technology for modern information display, LED display screens are widely used in fields such as advertising, information release, and stage display due to their advantages of high brightness, low energy consumption, wide viewing angle, and bright colors. However, traditional LED display screens are usually single-sided designed and can only display information on one side, which limits their application potential in multi-directional information dissemination.

[0003] To meet the growing diverse display needs, double-sided LED display screens have gradually attracted attention. Such display screens can display different or the same information simultaneously in a limited space, greatly improving the space utilization efficiency and information dissemination effect. However, with the popularization of double-sided display screens, the design of their structure frameworks also faces new technical challenges.

[0004] The structure framework of a double-sided LED display screen not only needs to support two panels but also must ensure the overall stability and safety. At the same time, lightweight design has become a trend to reduce the weight of the device and lower the transportation and installation costs.

[0005] Although the existing lightweight double-sided LED display screen structure frameworks have alleviated the weight problem to a certain extent, there are still some inconveniences in the actual installation and maintenance processes. These inconveniences mainly include:

[0006] 1. Complicated installation: The existing framework designs often lack modularization and standardization, resulting in cumbersome and complex installation steps, increasing the labor and time costs and being unfavorable for rapid deployment.

[0007] 2. Inconvenient maintenance: During daily maintenance and panel replacement, the existing designs usually require the disassembly of a large number of structural components, which not only increases the maintenance difficulty and downtime but also may cause component damage or loss, increasing the maintenance cost.

[0008] Therefore, developing a lightweight double-sided LED display screen structure framework that is easy to install and maintain has become an urgent need in the current technical field. In view of this, we propose a lightweight double-sided LED display screen structure framework. Content of the Utility Model

[0009] The purpose of the utility model is to provide a lightweight double-sided LED display screen structure framework to solve the problems raised in the above background technique.

[0010] To achieve the above purpose, the utility model provides the following technical solutions:
