I just check one of my favourite sites on news and found this amazing article. I suppose you read all through it. But for those who don't have time, here you have a short summary:
Today computer screens for blind people are expensive and only show one line at a time. The North Carolina State University is making an effort on developing a tactile display for more than one line. This means that blind people would be able to "read" images and text at the same time with more than one line. It's a "hydraulic and latching mechanism" which allows to raise dots at the hight that is needed to display the letter/word/image accurately! The good thing about it is that it is inexpensive!
And here is an image of how it works. Unfortunately the quality is not as it's best. But i think to understand the principle it's sufficient.

But the original source and probably best source to follow the project is on NCSU (North Caroline State University)
