摘要：随着社会信息化进程的加快，LED显示屏在信息化显示领域的应用将会愈加廣阔。目前LED显示屏的维护主要分为三大类，即前维护、后维护和前后维护。前维护可以大大减少LED显示屏结构整体的厚度，既能很好地与周边建筑环境融为一体，也能在保证效果的同时节省空间。前维护的应用相对后维护较广，而成本、结构复杂性相对于前后维护结构较低，因此，前维护的技术发展至关重要。而现有的各种前维护结构均是基于具体的安装、维护问题而提出的，还存在维护时模块破损、便利性、节能等方面的问题。本文给出了LED显示屏前维护技术的具体技术发展脉络，以期为LED显示屏前维护技术的发展趋势提供参考。

Abstract： With the acceleration of the process of social information， the application of LED display in the field of information display will be more broad. At present， the maintenance of LED display is mainly divided into three categories， namely pre maintenance， post maintenance and pre and post maintenance. Pre maintenance can greatly reduce the overall thickness of LED display structure， which can not only integrate with the surrounding building environment， but also save space while ensuring the effect. The application of pre maintenance is wider than that of post maintenance， and the cost and structure complexity are lower than that of pre maintenance. Therefore， the development of pre maintenance technology is very important. The existing maintenance structures are based on the specific installation and maintenance problems， but there are still some problems such as module damage， convenience， energy saving and so on. This paper gives the specific technical development context of LED display pre maintenance technology， in order to provide reference for the development trend of LED display pre maintenance technology.
