Abstract
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.
