A segmented alphanumeric includes a display panel, at least one linearly actuated platform, and display elements. Each display element passes through an orifice in the display panel to generate protruded and segmented alphanumeric characters in combination with other extended display elements. A microactuator array is displaceable by the linearly actuated platform and includes electromagnets and rotors. Each rotor is mounted for rotation in at least one direction between an active state and an inactive state by at least one associated electromagnet. Each display element is displaced through the orifice by actuation of the linearly actuated platform via a respective rotor when the respective rotor is rotated into its active state and to evade displacement by the rotor when the rotor is rotated into its inactive state.
