Just throwing this out there… there has been many research studies showing that rapid motion in a localized area can cause phantom sensations. When it comes to braille, if one of 8 pins within a character misinterpreted, the aggregate meaning of the phrase is lost.
What you’re advocating after all is a system where the character display pulses at a certain frequency, and if the operator misses a character because they had an itch or weren’t paying total attention, they’re now lost.
A braille terminal gives more than just letters, numbers, and punctuation. It provides spatial meaning to that information, along with control to the user where they can advance to when they have ingested the information to their satisfaction.

I imagine a keyboared coupled with a display was born out of a need not to move the hands so far, or perhaps the use of Braille notetakers had something to do with it.
In terms of using only a single Braille cell, I think this has been tried (Google the BraiBook). I've not used one extensively, but I would presume motion of the finger is used to read Braille as much as anything else. I can't imagine pins appearing legibly under a static digit doing much for reading speed.
