    摘要： A projection system is disclosed that has a light source of multiple wavelengths, a spatial light modulator and projection optics for projecting an image to be viewed by a viewer or to be displayed on a target. Also provided are one or more color sequencing devices which filter the light multiple times. Whether a single or plural color sequencing elements are provided, a single light beam passes at least twice through a sequence of light filters. In one embodiment, two color wheels provide the ability to filter the light multiple times. By changing the physical position or phase of one series of filters relative to another, the brightness and color saturation of the image projected through the projection optics can be changed. The changes in brightness and color saturation can be performed manually by mechanically changing the phase (or position) of the color sequencing device(s) relative to the light beam. Such changes can be performed step-wise of gradually through a continuum of brightness vs. color saturation points.

    摘要： A color wheel is disclosed that has at least one segment that occupies, for a given radius, a percentage of the circumference of the wheel at that radius, which percentage varies continuously or in multiple steps from a radially inward point to a radially outer point on the wheel. In one embodiment, the color wheel has a plurality of filter segments adjacent each other around the circumference of the wheel, wherein at least one of the transitions from one filter segment to the next is curved or stepped.A color wheel also is disclosed that has a plurality of filter segments adjacent each other around the circumference of the wheel, wherein at least one of the segments is a higher brightness segment than the others and has sides facing adjacent filter segments that do not lie on the radius of the wheel. A projection system is also disclosed that has a light source, a unique color wheel, a spatial light modulator, and projection optics.

    摘要： The present invention provides a microstructure device comprising multiple substrates with the components of the device formed on the substrates. In order to maintain uniformity of the gap between the substrates, a plurality of pillars is provided and distributed in the gap so as to prevent decrease of the gap size. The increase of the gap size can be prevented by bonding the pillars to the components of the microstructure. Alternatively, the increase of the gap size can be prevented by maintaining the pressure inside the gap below the pressure under which the microstructure will be in operation. Electrical contact of the substrates on which the micromirrors and electrodes are formed can be made through many ways, such as electrical contact areas, electrical contact pads and electrical contact springs.
