There are several firms. KGS in Japan make braille display cell technology.
VFO Group in the US do likewise (they formed as a merger of Freedom Scientific
and Optelec, and recently acquired AI Squared, but the latter isn't relevant
in this discussion).

Metec in Germany are a braille display cell manufacturer also. I don't know whether
HIMS in South Korea manufacture their own or acquire them from elsewhere.

For anything official, you would need to contact a vendor (and whatever
details they provide would only apply, strictly speaking, to their products).
