呵呵 我来发下我这一周的作品（点阵显示）
LED点阵显示，如有做点阵显示的可以拷贝一下
LED显示条屏：由32*64=2048个点构成，双色（可构成红、绿、黄三种颜色）；
条屏具体面积：长30.4cm×宽15.2cm。本显示条屏可显示8个小汉字，2个大汉字。
如显示汉字不够，可级连点阵屏或进行滚动显示。
1：货物名称及数量：LED显示条屏；有少部分条屏有一个坏点
2：价格：60元一块
3：成色：二手
4：物品缺陷及改动：
5：三包或保修期：无保修，凡出售，不退货
6：卖家所在地：四川成都西华大学，
7：卖家联系方式：QQ：274835389
8：淘宝连接：http://auction1.taobao.com/auction/item_detail-0db1-0e4d81d09233333007821fc7f4a33a80.jhtml
9：运输方式及运费（圆通快递：四川省内13元一公斤，四川省外15元一公斤）：
