Tactile pindisplay for blind aid and three dimensional pindisplay using Shape Memory Alloy micro actuators has been fabricated and developed. Character and graphic information are dynamically displayed by making pins array up and down. Magnetic material tube is attached to each pin and a permanent magnet fixes position of the pins up or down state. The mechanism solves problems of heat storage and electrical consumption of the SMA actuator because the current is supplied only when the pins move.
