Description

LED signboard cabinet including step prevention section}

The present invention relates to an LED display cabinet, and more specifically, to an LED display cabinet including a step prevention unit that can prevent steps from occurring during the installation of multiple LED display cabinets.

In general, companies use various advertising means to inform consumers of the excellence of their name or product and that they are an excellent company through advertising. As shown in Figure 1, LEDs are installed inside the fixed frame. A light emitting diode (light emitting diode) panel illuminates graphic advertising text using a fixedly placed electronic signboard.

The use of the above-described electronic signboard as a means of promotional advertisement, notification, or attraction by installing it outdoors is increasing.

According to the above-mentioned conventional electronic signboard, the electric signboard had to be manufactured in a large size to maximize the advertising effect, and the large-sized electric signboard had serious problems in rapid installation, disassembly, and transportation due to its weight.

On the other hand, there was a problem that it was impossible to transform the electronic signboard into a unique and unique shape that matched the surrounding environment, atmosphere, and decoration.

In addition, when using multiple electronic signboards to form a large electronic signboard, there was a problem that it was inconvenient to replace if any part was defective or defective, and as a rectangular frame with a thick width was used, the angle had to be changed when expanding the side. When this happens, there is a problem in that the gaps between the two become large, which has a negative impact on the advertising effect.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
