LED advertising screens have gradually become the first choice for users as the carrier of outdoor advertising. The multiple advantages of color and image quality and the ability to change any screen are deeply implanted in the hearts of users. In the foreseeable future, the LED advertising screen market will account for 80% of all outdoor advertising tools. The biggest advantage of billboards and LED advertising screens is that LED advertising screens can switch various advertising information at any time. Billboards are static, while LED advertising screens are dynamic, which is easier to attract people's attention. In the early days, due to the high price of LED advertising screens, many advertising companies used static inkjet or banner billboards to display. The disadvantage is that the advertising content is single, and the advertising fee paid by the advertiser is high, and the replacement of the advertising content requires manual on-site Replacement is costly, and as the price of LED advertising screens gradually becomes popular, many owners who place advertisements can find a place to build them by themselves, which will greatly promote the rapid expansion and development of the LED advertising screen market. LED advertising screens are usually installed in outdoor columns, wall advertisements, vertical advertising machines in hotels and shopping malls, etc. As the LED advertising screen market gradually matures, combined with the actual needs of users, the control and installation methods of LED advertising screens will also change. Further optimization, the obvious progress is that the LED advertising screen was controlled in real time by the computer in the same place before, but now it can be controlled wirelessly in different places, wirelessly controlled by mobile phones or wirelessly controlled by computers in the same place, etc.
