Sounds interesting and perhaps it would work
I was thinking possibly of something like this
http://www.neosecsolutions.com//products.php?28&cPath=17
It is actually a slightly smaller area than a credit card.
But I would need to work out how much battery capacity the screen would use.
There are some pretty powerful battery packs available on-line for
charging phones that might do the job.
They seem to have a higher capacity than some laptops!
