上图才是关键。又是黑白屏吧，我手里也有个老的黑白屏，还是高压背光。懒得摆弄了，除了耗电多使用麻烦，没有别的特色。

用硬封装控制器的屏还是很容易玩起来的，驱动容易，也不怕找不到资料。

只是现在还有几个人喜欢单色屏呢？

2楼真理，上图才是关键

chenghj · 发表于 2014-4-23 12:45

贴上来的注解都乱码，求上完整程序学习学习

ipoeer · 发表于 2014-4-23 14:25

玩黑白屏就复古的感觉，，

8055 · 发表于 2014-4-23 14:32

我还是比较喜欢黑白屏或者EL之类的屏，至少在某些专业领域我认为挺好的

fujiachun · 发表于 2014-4-23 16:16

无论什么屏，点亮了就是高手

ciddy · 发表于 2014-4-23 17:21

上图，是什么样的屏都，不知道
