就是先用字库显示汉字然后把有汉字的地方全部用绘图写FF就可以把汉字反白了，这是我无意中发现的，呵呵

相当不错的程序，可我还是有两个小小的问题，前面51楼和71楼的朋友已经说过了，但我还是想说一下，就是显示字母和数字的时候，如何只对奇数的字母反白，打个比方说：我显示屏上第一行显示的是时间18:29:34现在我要对分钟进行修改，也就是要让29反白，我该如何实现呢，再者就是，我用此做菜单的时候，就出现了71楼说的情况，反应实在太慢了，我字都送上去好久了，才反白，刚开始我还以为是我的按键没用了呢，请楼主和各位大神指点一下，非常感谢。{:smile:}

哈哈十一回家时逛街顺便买了个摄像头玩玩。来上几个液晶反白的效果图。效果不好，让大家见笑了。
正筹划着 ...

请问下，单个字符能反白吗？看你的是单个汉字。

3线模式好啊，省资源！

自己顶一下，可惜没有相机，要不可以传几张效果图上来了。那个有兴趣把这个程序试一下，并拍几个图片上来啊 ...

请问一下这个可以实现单个字符的反白吗？我看你写的是任意位置汉子的反白~~
