ABSTRACT:Along with social culture fast development, People's expense standard changes unceasingly. The outdoor lamps advertisements are playing more and more important propaganda roles. It looks everywhere such as train stations, stock trading markets and schools. But the traditional neon light billboard is unable to satisfy current social the demand in demonstration effect. It has got a great disadvantage such as modifiability. The traditional neon light advertisement wants to be improved urgently. So using the LED electrical display monitor has got the huge social efficiency and the economic efficiency.

随着社会文化的不断发展，人们的消费标准不断改变，户外灯箱广告更是扮演着越来越重要的宣传角色，不论是汽车站，火车站，股市交易市场，还是学校都离不开它，然而传统的霓虹灯广告牌不论是在显示效果、耗电量还是可修改性上都无法满足当前社会的需求，传统的霓虹灯广告急待改进，使用LED电子显示屏，有巨大的社会效益和经济效益。
