Description

一种LED显示模组、LED显示屏及其控制设备 技术领域
本申请涉及LED领域，特别涉及一种LED显示模组、LED显示屏及其控制设备。
 背景技术
目前，LED（Light Emitting Diode，发光二极管）显示屏是由多块小LED显示模组通过各种不同的方式拼接而成的大型显示器，它通过控制LED的发光来实现文字、图像、视频等各种媒介信息的显示。LED显示屏由于具有无缝拼接、高亮度、低功耗、性能稳定等其他显示屏无法比拟的优异特性，现已广泛应用于铁路民航、体育场馆、会议厅、高速公路、广场、大型商场、证券市场、安防监控等各大领域。
随着科技全产业链的不断发展，产品智能化已成为众行业的最重要的课题，LED显示屏也不例外。可以预计的是，LED显示屏系统将从功能简单、单一设备、封闭性控制和手工操作逐渐发展成自动化、网络化、多功能集成的智能化信息显示系统。但是，从目前大多数LED显示屏的使用情况来看还并没有实现真正的智能化，还仍然处于比较初级的应用层面，市面上一些所谓的智能LED显示屏往往只是集成了某些常见的功能模块而已。
当前多数LED显示屏的数据传输是单方向的，控制系统通过输送数据控制显示模组，而显示模组没有反馈数据，控制系统无法对显示模组进行分析判断，使得LED显示屏无法像其他智能显示终端一样实现诸多智能化功能。另一方面，当前在显示模组中增加Flash存储器或将接收卡集成到显示模组的方案带来了很高的成本，性价比太低。
另外，当显示模组没有反馈数据时，LED显示屏就会有诸多不足：其一，控制系统往往无法自动识别显示模组的信息及工作状态，实现播放和维护都需要专业的、复杂的手动操作；其二，显示屏的供电模块无法根据显示模组的信息和状态来实现智能供电和省电，带电插拔时容易烧坏显示模组，且黑屏功耗很高。
