About Alva Braille Displays

In the mid-1980s the Tieman Group, known today as Optelec, developed the first refreshable braille display using state-of-the-art piezoelectric braille cell technology. The piezoelectric cell technology changed the face of braille cells forever as it was the first technology that could withstand the weight of the finger so you can read the braille while its refreshing. Since then, the Optelec braille cell has continued evolving, improving the feel of the dot and the portability of the cell today, making it one of the most popular braille cells used in most braille displays and notetakers world-wide.
