    摘要： A projection apparatus implemented with a mirror device that includes a first electrode and a second electrode with an elastic hinge disposed between the first electrode part and second electrode. The elastic hinge supports a mirror and the mirror is controlled to deflect when drawn by a Coulomb force generated between the mirror and electrodes by applying a voltage to the electrodes. The projection apparatus further includes a light source for projecting a light to the mirror for modulating the light by deflecting the mirror to different deflection states. The light source suppresses the emission of the illumination light during a period when the mirror performs a series of operations to shift from a non-deflection state, placing the mirror in a stationary and non-deflection state, to a predetermined deflection state.

The display system further includes a deflectable mirror device having a plurality of mirror pixels. The display system further includes a polarized light separation plane that separates reflected light from the illumination light, a wave plate disposed near the deflectable mirror device, and a projection lens that projects the reflected light from the deflectable mirror device. In this system, the optical axes of the illumination light and an ON reflected light reflected from the deflectable mirror device are substantially perpendicular to the deflectable mirror device, and the optical axis of an OFF reflected light is inclined to the optical axis of the image display projection light path.
