Yes the problem with those is resolution. I have actually seen many of those
displays. As for braille speed. I haven't been reading braille for 30 years
of my 50 years and I am so slow reading children's books take me all day. I am
an audio learner. I took all three calculus classes audibly and aced them
because I can invasion the problems. At any rate that doesn't mean the braille
devices are not useful. Like I said earlier I use the braille displays to show
what a sighted person would see on a 7 and 8 segment display. It takes 5 cells
to do it but it works. On the graphiti I can do it much easier because it’s
a graphic display but I like making things like a digital simple volt meter
with an Arduino some electronics parts and a braille display. You don't have
to read braille to make tactile devices useful.

I'll admit, I know nothing of the conferences of which you speak, and often
times, when I do bother researching the latest developments in blind tech, I
mostly come across things that would be cool to have, but which are way out of
my budget... and honestly, my Braille reading speed is so slow that I doubt
even a sub $50 display with a decent cell count would catch my attention.
That said, I think the last time I was this excited over something in the realm
of tactile displays was when an article about the Tesla Touch made it into
Choice Magazine listening several years ago...
though sadly, nothing ever came of that as far as I know. In case you haven't
heard of it before, it was an experimental touchscreen that used electrostatic
vibration to simulate changes in texture.
Another case of Google being more or less useless because of something else
with the same name, but here's a Wikipedia article on the underlying phenomenon:
