贴图不成功，把接口定义放在下在。
如题，接口分别为：
GND        A
GND        B
GND        C
EN           D
R1          G1
R2          G2

我先前实验的一块屏是08接口的单色屏，为F3.75的小屏，各种显示都是正常的。我现在手中的两块屏，都是08接 ...

亮与不亮的间隔时间是多少？电源功率是否足够？控制卡扫描频率是不是设的太低导致屏保护？

亮与不亮的间隔时间是多少？电源功率是否足够？控制卡扫描频率是不是设的太低导致屏保护？

时间间隔好像是随机的，没有一定的间隔时间。扫描卡的扫描频率好像没有问题，在F3.75的屏上扫描是正常的。关于电源功率够不够，我也想到了，正在想找个较大功率的电源来试一下。

应该是可以用的

昨天搞了一天，问题还是没有解决，换了个功率大的电源，依然没有点亮屏。想问一下，市场上出售的标准的08接口的屏是不是通用的？还是一种08接口的屏，对应的是相应的控制卡，其它的控制卡不能用。也就是说一种控制卡必须要配置相应的屏，换一种08接口的屏就不能用了？

08接口理论上都是一样的，方便的话可以拍张屏背面的照片，大伙可帮忙 试着分析一下。

两块不同厂家08接口的单色屏，从板上的元件来看也基本上一样。用同一个控制卡驱动，一块屏可以正常显示，另一块屏出现的好像是隔扫描的效果，问题会出现在哪儿呢？

程序也改过试了，还是1664的大板点不亮。我仔细查看了一下，两块显示板所用的元件，竟然是一样的，都是由8个595、一个HC04（六反相器）、二个HC245和二个138组成，驱动用的是4953。程序也是一样的，控制器用的是同一块板，但小板很容易就点亮了，大板就是点不亮。但大板也没有坏，我修改了几套程序分别试了，小板都可以正常显示。但大板就不行，有时上面有不规则发光点闪烁。多数时候是不亮。

字符在显示的过程中，只能显示奇数行的点阵，而所有偶数行的点阵都不显示，这是怎么回事？变成了隔行显示了。但同一块控制板去驱动我的F3.75显示板却是正常的。这样的问题应当如何解决？
