In this paper, a color spatial light modulator has red, green, and blue micromirror arrays juxtaposed in parallel, each of which has a filter for reflecting specific color light.
Abstract: 
A color spatial light modulator has red, green, and blue micromirror arrays juxtaposed in parallel. Each micromirror array has a number of micromirrors each formed with a filter for reflecting specific color light. As data "1" is written to a memory cell of an SRAM, the micromirror tilts by +θ and enters a valid reflection state in which spot light is utilized. As data "0" is written, the micromirror tilts by -θ and enters an invalid reflection state in which spot light is not utilized. A data write control circuit converts image data into mirror drive data and writes it to SRAM. Three-color parallel line light beams generated by the three-color micromirror arrays are projected by a projector lent onto color paper. A three-color image is printed line sequentially on the color paper.
