OK, this has been running 24/7 as my alarm clock now since about 01/07/2014
 http://www.ebay.com/itm/171069574803
  in this project:
   http://panteltje.com/panteltje/pic/gm_pic2/
It is on now, and charging at the same time.
That is about 3 years or 24 * 365 *3 = 26,280 hours.
It is running at lowest brightness, and that is bright enough.
I do not see (but have not measured with a light meter) any degradation or other defects.

I guess luck is with me, as the lipo in it has now been recharged 365 * 3 = 1095 times,
something that is not possible either ;-)

I have more of these displays in use, for example:

   very good readable in bright sunlight, even with the protection foil.
