Vibration type tilting device

Abstract

A tilting device for repeatedly tilting light reflected from a micro-mirror panel is disclosed. A vibration type tilting device, comprising a mirror positioned on a light path which reflects light transmitted from a digital micro-mirror panel, a mirror holder having the mirror joined to a side thereof, a coil joined to the reverse side of the mirror holder, and a magnet which generates a magnetic field passing through the coil, where portions of the mirror holder are removed to decrease the mass moment of inertia of the mirror holder, may not only provide a smooth and natural display by periodically tilting light reflected from a digital micro-mirror panel in constant time intervals but also may improve the tracking ability of the mirror and reduce residual vibration.

Dependencies are inferred from the claim text.
