Figure 5. Schematic diagram of rotating micro-mirrors.

The left is the top view of four micro-mirrors, while the right is the cross-section of one micro-mirror. The micro-mirrors which flip to the 12 degrees positions are depicted in aqua, and the ones turning to −12 degrees in cornflower blue. The exposed surface under the micro-mirrors is represented in dark gray, and the gaps between adjacent micro-mirrors in light gray.
