LED点阵显示外文文献及翻译译文：大屏幕显示系统得研究LED得发展随着计算机技术得高速发展，LED屏幕显示系统作为继电视、广播、报纸、杂志之后得“第五大媒体”正快速步入社会生活得各个方面 它集微电子技术、计算机技术、信息处理技术于一体，可以将信息通过文字、图案、动画及视频四种形式显示出来 与电视墙、磁翻板等媒体相比，LED大屏幕显示系统具有图案美观、色彩亮丽；图案、色彩变化丰富、快速；低功耗、长寿命、使用成本低、工作稳定可靠等特点 它显示得图文视角大、视距远，因而已广泛应用于大型广场、商业广告、体育场馆、信息传播、新闻发布、证券交易；它还应用于工业控制和工业调动系统，便于把各种参数、报警点、工艺流程显示的更加清晰完美，可 tethatthedifferentcontent,thedisplaymodeisrich.Thereforeinthepublicarea,ithastheintenseadvertisementspropagandaandtheinformationtransmissioneffect,alreadyinthesoliddemonstrateddaybydayoccupiesthedominantposition.TheLEDdisplaymonitorsprospectsfordevelopment。
