是否必须是电子纸，不能使用VGA（或HDMI）输入的平板（LCD，TFT）工作。我的意思是你可以移除挡板并将其安装在自定义挡板上，然后使用PC104，Raspberry PI，Adrino或许多其他类型来驱动它。将控制器板连接到大学网络，***从网络获取更新并继续！电子纸虽然看起来很好，但对于这个项目来说可能会过度杀戮（你也可以在你的写作中建议进一步的工作！）。

Does it have to be E-Paper, wouldn't a Flat panel (LCD, TFT) with a VGA (or HDMI)input work. I mean you could remove the bezel and mount it in a custom one and then use a PC104, Raspberry PI, Adrino or many other types to drive it. Hook up the controller board to the college network and it is good to get updates from the Network and go! E-Paper while it looks, good might be over kill for this project (you can also suggest it a further work in your write up!) .

一个大的 LED 面板怎么样？所有的乐趣都在控制方面：PC与微控制器通信，而微控制器又驱动硬件。

What about a big LED panel? After all the fun is all in the control side: PC communicating with a microcontroller that, in turn, drives the hardware.
