Abstract
The invention provides a digital micromirror device control apparatus and a projection display system. The digital micromirror device control apparatus includes a video decoding circuit configured to decode received video data, thereby obtaining component data signals of a plurality of colors; a digital micromirror device driving circuit including a first sub-driving circuit and a second sub-driving circuit. An input end of the first sub-driving circuit is connected to the video decoding circuit, an output end of the first sub-driving circuit is connected to the first digital micromirror device, an input end of the second sub-driving circuit is connected to the video decoding circuit, and an output end of the second sub-driving circuit is connected to a second digital micromirror device. The first sub-driving circuit and the second sub-driving circuit are configured to process component data signals of at least three of the plurality of colors.
