Refreshable Braille displays use piezoelectric elements to drive the dots these days. Very little difference in cost between 6 and 8 dots per sell. Moreover, unless the number of blind folks increases drastically, we are unlikely to garner the monetary subsidies you suggest. Plenty of research is going on but, frankly, most is impractical and IMO little more than hot air from inventors looking for money.
