Whats the difference between the 700TSV and 705TSV
Am a newbie to this, and just working on my first project.
I think i've decided to go for a Xenarc touchscreen as they seem to have better quality (brighter) screens and more responsive as a touch screen from what i've read (you may correct me on this).
I'm looking to buy something like the 700TSV which seems to be a common screen, but noticed there's a 705TSV as well. I can't see what the difference is, although the 705TSV seems to be £20 cheaper.
Alternatively the 840TSV seems to be cheaper than the 700TSV as well. Apart from the obviously larger size, is there any other difference?
PS i may have many more questions to ask in the coming weeks, as my project progresses ;o)
