IonTouch displays content by driving black or white ink particles contained in e-paper film. The e-paper film, functioning as display media, can display content permanently without using power and be rewritten for more than 10,000 times. Currently, IonTouch display features resolution of 300x300dpi in black and white and 16 levels of gray scale.
