摘要： An optical projection system, displaying an image of pixels on a projection screen, includes a light source for generating a white light beam, wherein the white light beam has a first, a second and a third primary light components, each of the primary light components being one of the primary colors, a pixel filter for filtering the white light beam into each of the primary light beams of each of the primary light components, wherein the pixel filter made of a set of R, G, B color sections, and an array of M.times.N actuated mirrors provided with an active matrix, M and N being positive integers, respectively, each of the actuated mirrors being capable of reflecting the white light beam from the light source to any one of the color sections and modulating an intensity of the light beam passing through the pixel filter in response to an electric signal applied to the active matrix. In the system, the electric signal includes a plurality of time interval corresponding to a pixel driving time, wherein each time interval is divided into three time slots to be allocated to the color sections, respectively.
