A 4-V operational organic Braille display is demonstrated, for the first time, by integrating organic static-random-access-memory with a carbon nanotube-based actuator and organic thin-film transistor driver. Taking advantage of new organic materials and process engineering, an actuator displacement of 300 μm has been achieved within 4-V operation in air, a size that is large enough for a blind persons to recognize whether individual dots are in an up or down state.
