液晶是多少伏供电的

huhuan6 发表于 2011-3-31 15:25:31

背面标签上贴的是3.3V

liuzq1981 发表于 2011-3-31 15:29:03

需要调节清晰度吗

huhuan6 发表于 2011-3-31 15:30:01

这个无所谓，关键是现在什么都不显示啊

huhuan6 发表于 2011-3-31 15:30:32

我不知道程序上是不是有问题？

ricefat 发表于 2011-3-31 15:31:28

液晶负压接了没？

liuzq1981 发表于 2011-3-31 15:32:35

你这个液晶好像需要调节外部电位器，来调节清晰度，要不然显示不出来的

huhuan6 发表于 2011-3-31 15:33:02

接了一个电位器10K,VO大概-2.5V的样子

liuzq1981 发表于 2011-3-31 15:35:20

打开背光，好好调一下

huhuan6 发表于 2011-3-31 15:35:48

OK了，我调到了-7V,谢谢了！

huhuan6 发表于 2011-3-31 15:38:58

这个液晶VO调到-6.5V才有反应，郁闷啊，在程序上折腾了两天！

huhuan6 发表于 2011-3-31 16:09:49

问题解决了，谢谢楼上的，圆满结贴！

liuzq1981 发表于 2011-3-31 16:55:42

哈哈，以后出问题还要慢慢来，先把最基本的问题弄清楚。

like0831 发表于 2011-4-29 21:45:22

皆大欢喜！

guisi 发表于 2011-5-20 10:36:14

学习了

ljmdzyx 发表于 2011-12-29 17:52:37

马克…
