Has anybody tried epaper ?

I was thinking epaper might be handy for some brightly lit applications. The display remains after power down, very handy.

I just spotted this old post.  I'm working on a project hat needs a display that can operate for a long time on battery.  E-paper looks like it might be the answer.  I'm looking at some of these: Buy-LCD E-paper.  Some of them have an available SPI controller: E-paper W SPI

Has anyone used an E-paper display with a PIC?

Thanks!

Hi Rick
I have not yet tried E-paper and will be interested in any usage reports.
I was in our local Aldi store a couple years ago when the price label on something I was considering purchasing started flashing in an unstable manner, the price changed before my eyes, examination of the label showed no wires, most impressive.  I spoke to the store manager learning about the e-paper labels. The labels are very clear and have an impressive viewing angle. If you want I will enquire about the reliability of the labels. I have not noticed any dull or failed labels. It would be good if Aldi sold it's labels, they must buy millions.

May be handy for certain applications to have a displayed message when power has gone.  Especially here in Sick Africa where we could have a permanent power failure at any time, which was warned about already.("Last Power on date and time") - Could become a historic item.
Or perhaps somewere in the distant future they may dig you up and find the display with it's last message ("Grandma's secret recepe")  People like to discover secrets... or perhaps it will be aliens who discover the message.

Here is another set of display's you may be interested in.

They range from small to large
You use jpg images to create annimation, place buttons etc using a program called DGUS (PC Display must be set on very high resolution to use).  The display controller runs the graphics and your micro send the values and functions to the controller.  You can make magic without having to use large coding.

And a larger display

Just think of the nice instruments one can make with a screen like this.
