This Small Business Innovation Research (SBIR)Phase I proposes using micro electro-mechanical systems (MEMS) technology to make low cost, high definition display elements in the application of digital projector display. In the proposal, the display uses electrostatically-actuated light modulators in which a beam of light is directed towards a light valve target, e.g., an array of micromirrors. The micromirrors response to a video addressing signal, imparts a modulation onto the light beam in proportion to the amplitude of the deflection of the individual reflective micromirrors. The amplitude or phase modulated beam is then passed through projection optics to form the image. The digital projector display market, including business projectors, televisions, and portable Displays, has been growing continuously, and reached the size of ~$4 billion in 2002. The key Performance criteria for displays are brightness, contrast ratio, resolution, uniformity, and optical Efficiency. The market for low cost, high brightness projection display is expected to grow at a rate of 120% until 2005. In 2005, the estimated market size is ~6 million units for home projectors only, about 60 times of the market size in 2001 (98,000 units).

这项小型企业创新研究（SBIR）第一阶段提出使用微机电系统（MEMS）技术，使低成本，高清晰度的显示元件在数字投影显示的应用。 在该提议中，显示器使用静电致动的光调制器，其中光束被导向光阀目标，例如，微镜阵列。 微镜响应于视频寻址信号，与各个反射微镜的偏转幅度成比例地对光束进行调制。 振幅或相位调制的光束然后通过投影光学器件以形成图像。 数字投影机显示市场，包括商用投影机、电视机和便携式显示器，一直在持续增长，2002年达到约40亿美元的规模。 显示器的关键性能标准是亮度、对比度、分辨率、均匀性和光学效率。低成本、高亮度投影显示器的市场预计到2005年将以120%的速度增长。 2005年，仅家用投影机的市场规模估计为600万台，约为2001年市场规模（98，000台）的60倍。
