In this paper a concept for hardware realization of graphic tactile displayfor visually impaired peoples is presented. For realization of tactileactuators bi-stable, solenoids and PIC based control board are used. Theselected algorithm for series activation of each row of display allows usingminimal number of active components to set and reset the solenoids. Finally, aprogram algorithm of control board is discussed. The project is funded byBulgarian National Science Fund NSF Grant D ID 02 14, 2009 2013
