A vibration type tilting device, according to an embodiment of the invention, which comprises a mirror holder, supporting a mirror on one side, which tilts together with the mirror such that the mirror periodically tilts light on a light path in a minute angle; a holder support part supporting the mirror holder; a driving part, which supplies driving power to the mirror holder; and a damping part comprising a gap adjustment member capable of changing the gap between a portion of the mirror holder and a portion of the holder support part, provides superior vibration characteristics, as the viscous fluid is not heated by the driving part.

Vibration type tilting device and damping adjustment method therefor

A vibration type tilting device, according to an embodiment of the invention, which comprises a mirror holder, supporting a mirror on one side, which tilts together with the mirror such that the mirror periodically tilts light on a light path in a minute angle; a holder support part supporting the mirror holder; a driving part, which supplies driving power to the mirror holder; and a damping part positioned between the mirror holder and the holder support part to reduce overshoot of the mirror holder, can improve the vibration performance of the tilting device to provide a smoother and clearer picture quality.

Vibration type tilting device

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.

A tilting device is disclosed which tilts the light reflected from a Digital Micro-mirror device by a certain angle and projects it to a screen. The tilting device, comprising a first reflector surface, a second reflector surface inclined at a predetermined angle with regard to the first reflector surface, a holder attached to the bottom of the first reflector surface and the second reflector surface, and a driving part that provides rotational force to the holder, wherein the first reflector surface and the second reflector surface are rotated by the driving part to sequentially reflect light emitted from a Digital Micro-mirror device, not only provides a smooth and natural display with invisible grids but also allows more stable and more accurate tilting.
