Classification: CPC G  H | IPC G  H

Claim 0:
1. A projection system, comprising:
a light modulation device configured to modulate incident light based on image data to form image light for displaying an image corresponding to the image data, wherein the light modulation device comprises a plurality of micromirror units, each of the plurality of micromirror units comprises an irradiation region comprising a plurality of sections, each of the plurality of sections corresponds to one pixel in the image, and incident light irradiating one section of the plurality of sections is modulated to form image light of a pixel corresponding to the one section;
a light source system configured to emit one or more illumination sub-beams, wherein the one or more illumination sub-beams irradiates one of the plurality of sections; and
a light deflecting device configured to shift the illumination sub-beam from one section of the plurality of sections to another section of the plurality of sections of one of the plurality of micromirror units in such a manner that each of the plurality of sections of each of the plurality of micromirror units modulates the one or more illumination sub-beams in a time division manner to form image light of a pixel corresponding to the section.
