Patent ID: 7433107

Claim:
A scanning display system, comprising: a micro mirror unit, which comprises a micro mirror, for forming a linear scan region by reflecting input light while reciprocally rotating in two directions; a substrate for supporting the micro mirror while the micro mirror rotates, and connection members for connecting the micro mirror to the substrate; and a galvanic mirror unit, which has a rotational axis that is perpendicular to a rotational axis of the micro mirror unit, for forming a two-dimensional scan region by receiving and reflecting the linear scan region while reciprocally rotating in two directions, wherein a scanning speed of the micro mirror unit is faster than a scanning speed of the galvanic mirror unit, and wherein the micro mirror comprises a mirror plate and movable comb-teeth-shaped electrodes formed beside both ends of the mirror plate, and the substrate comprises fixed comb-teeth-shaped electrodes, such that the micro mirror is reciprocally rotated by electrostatic force that is generated by a potential difference caused by applied voltage.
