LVDS panels aren't uncommon. In fact, I believe (but not checked) there should be lots of them being sold as replacement parts for notebooks and tablets.

For example, relatively recently there was a post on HN about RaspberryPi-based DIY tablet. It had this link for LCD panel: http://www.chalk-elec.com/?page_id=1280#!/~/product/category.... The store page now says it's discontinued, though, but this was meant just as an example and I'm too lazy to search for a better offers, sorry. :)

Although, those are probably of no use with AVR microcontrollers directly, without a display controller like http://blog.tkjelectronics.dk/2012/10/lvds-display-controlle... or http://hackaday.com/2009/12/12/fpga-driver-for-psp-screen/. Phone LCDs just have it already and panels don't.
