<p>This appeared in social media recently as well. Without
commenting on that particular proposal (or set of proposals), I
can say the following.</p>
<p>There have been many braille display cell technology proposals
over the last several decades, few of which have ever been
developed into products, and details of which can be found by
searching a patent database. I've learned to treat new such
proposals with scepticism, at least until there's a working
prototype demonstrated publicly and a plausible plan to
manufacture a device. Running a patent search online will give you
a sense of various approaches that have been tried.<br>
</p>
<p>In my experience, the low-cost displays tend to have usability
limitations, so I personally end up buying the more expensive
piezoelectric technology. There are interesting cell technologies
now from Dot Inc. and Tactile Engineering that could be genuinely
transformative, however.</p>
<p>The DotPad display from Dot Inc. appears to be supported by
BRLTTY. There is also the forthcoming Monarch display from APH and
HumanWare - not yet supported as far as I can tell from a quick
search. The devices from Tactile Engineering aren't yet supported
as far as I know.</p>
<p>Orbit Research also has multi-line braille displays, presumably
using their existing cell technology.<br>
