数字微镜器件（DMDS）是一种在投影系统中应用前景很好的显示技术。美国得克萨斯仪表公司的工程师们在这方面进行了有计划的研究开发工作。他们认为改善大DMD显示装置的关键是产生高效、长寿命的白色光源。他们近一年来取得的主要进展有：（1）改进微镜形态使开口率提高了33％?
Digital Micromirror Device (DMDS) is a promising display technology for projection systems. Engineers at the Texas Instruments company in the United States conducted a planned research and development work in this area. They think the key to improving large DMD displays is to produce efficient, long-lived white light sources. The main progresses they have made in the past year are: (1) improving the morphology of micromirrors to increase the aperture ratio by 33%?
