I think it depends on what level the smart aspect is implemented and how integrated it is. Screen technology has been getting more and more locked down by corporate privateers/thieves.
I mostly tried hacking on small displays, and finally gave up as it was over my head. There is a whole lot going on in various layers and protocols. My rule would be to only buy a product like this if I can find a functional example of someone using my exact hardware with this exact hack in question.
In my experience, prototyping or hacking around with displays is a losing game because they are not constructed for handling like this. You must go to extremes to avoid placing strain on the flex ribbon connections and must be very careful about taking the thing apart to test with it disassembled. It only takes a tiny mistake to damage something that can not be repaired. They are usually sensitive to small nonsense too. These are fast parallel circuits. I stay away from them, but maybe I'm just being soft.
