斑竹有没有再深入的研究下大屏的？交流下。

作者: zcllom 时间: 2008-10-6 10:27

多大的屏算大屏幕？要象车站里的信息播报屏吗？

作者: xymbtc 时间: 2008-10-13 00:17

是啊，需要考虑哪些因素？

作者: zcllom 时间: 2008-10-13 00:30

刷新速度是个大问题。我找找，记得我有一个大型LED点阵屏的文件。找到了就发上来

作者: clp1123 时间: 2008-11-17 13:59

你好我就是做大屏的可就是不会单片机现正想学呢,PCB我自己会,zcllom版主挺历害还会单片机能给小弟弄一个长6个字高2个字的单片机吗?有尝服务.
