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. > If no specifications are available, measurement is certainly a valid > way to get a reasonable estimate.

For anything official, you would need to contact a vendor (and whatever details they provide would only apply, strictly speaking, to their products). _______________________________________________ This message was sent via the BRLTTY mailing list.
