There are some, in particular the orbit reader[0] is much cheaper than a piezoelectric display. The trade off is that is is relatively slow to refresh and quite noisy. There is also the dot pad[1] which is much more like a screen with a rectangle of cells that can show Braille and graphics! It is a different technology using electromagnetic actuators with latching. It can only refresh when not being touched. It's also out of the price range of most consumers, but apparently the technology scales very well so they expect the price to fall. It is also modular so users can easily replace broken cells. The Monarch[2] is based on Dot Pad technology and also runs Android and Humanware's Keysoft software like the BrailleNotes.
