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.

摘要： Additional control flexibilities to generate more gray scales for an image display system is achieved by controlling the intensity distribution of the light projection from a light source to a deflecting mirror to further coordinate with the control of the intermediate states of the deflecting mirror. The control light source intensity distribution can provide incident light with wide varieties of intensity distributions including non-uniform, symmetrical and non-symmetrical, different distributions of polarizations, various cross sectional shapes of the incident lights and other combinations of all of the above variations. More stable and better control of gray scale control is also achieved by optimizing the intensity distributions of the incident light to produce the best visual effects of the image display.
