论文摘要求翻译 ！不要用翻译软件直接翻译，因为在句子上连接不上，谢谢！

LED广告牌是一种面向公众的信息显示终端，有着非常广泛的民用和商用价值。
LED可以给国家和使用者节省大量电能，给承做方节省大量工时。LED应用技术的发展，给竞争激烈的广告业增添了新的活力。其独有的、不同的发光形势、被广泛的应用在广告产品的制作领域。由于还没学到单片机，本文没有用单片机和LED显示屏，仅仅使用LED彩灯拼成所要显示的字，再由555产生脉冲信号，经过CD4017分配脉冲，来分别控制红绿霓虹灯的间隔闪烁及所要显示字的依次显示。
不要用软件直译谢谢！
1楼的你没有明白我的意思吗？ 不要用在线的翻译来骗积分，你看你的第一句就翻错了！ 我真悲哀~~~

has ???什么has 连主语都没有，看来又要没有答案了。

再看看下面的 LED to the ~~~~明显是在线软件翻译的 无语！

I can assure you that this one has been translated manually, but owing to my level, there will be mistakes.

Answer 2

LED billboard is a public-oriented information display terminal, has a very wide range of civil and commercial value.
