SBIR Phase I: High-Definition Pico-projector Display Engine Based on Lasers and Scanning MEMS Mirror

这个小型企业创新研究（SBIR）第一阶段项目提出了新颖的MEMS和光电系统设计和制造工艺，以创造世界上第一个高清晰度视频微型投影仪，这种投影仪是如此小型化，低成本和低功耗，可以在不久的将来与各种移动设备集成，如手机和上网本。提出的移动视频投影仪显示引擎由快速调制的RGB（红、绿、蓝）激光组成，由MEMS扫描镜在显示表面上以高清视频速率逐像素扫描。这种投影图像不需要在任何距离聚焦，并且由于使用激光，具有令人难以置信的颜色范围和质量。除了需要比现在更快、更大、更宽角度的扫描和光学更平坦的MEMS反射镜外，所提出的系统还可能需要创新的封装，以及更快、更节能的激光驱动器，这些都是现成的。将所有的显示引擎组件封装到一个小的外形尺寸将需要在光机械工程和适当的传热解决方案方面付出巨大的努力。第一阶段的工作将为显示引擎提供概念研究和设计工作的证明。这个项目更广泛的影响/商业潜力是满足消费者未来的需求，他们将要求在不断缩小的移动设备上拥有越来越大的显示能力。微型投影仪将与电脑、手机、pda或其他便携式电子设备一起使用或集成，预计在未来5年内市场规模将超过10亿美元。提出的高清晰度微型投影仪显示引擎的成功商业化将产生许多社会和商业影响。显示尺寸最终将与移动设备尺寸的限制脱钩。电影、商业演示、图片、社交网站等都可以更舒适地观看和分享。在可编程的棋盘游戏、自适应的家庭装饰以及其他领域都有新的可能性。相信该技术的高分辨率（XGA和HD 720p）和最高功率效率（10流明/W）可以充分实现这些影响并占领市场。这项技术，与高速网络的日益普及并行，将反过来提高更容易共享商业信息的能力，并加速娱乐内容的分发，甚至比现在更快。

This Small Business Innovation Research (SBIR) Phase I project proposes novel MEMS and electro-optical system designs and manufacturing processes to create world's first high definition video micro-projectors that are so miniaturized, low-cost, and low power consuming that they can be integrated in the near future with a variety of mobile devices, such as cell-phones and netbooks. The proposed display engine for mobile video projectors consists of fast-modulated RGB (red, green, and blue) lasers scanned pixel-by-pixel by MEMS scanning mirrors over a display surface at HD (high definition) video rates. Such projected images will not require focusing at any distance and with an incredible color range and quality due to the use of laser light. In addition to requiring significantly faster, larger, wider-angle scanning, and optically flatter MEMS mirrors than available today, the proposed system may also require innovative packaging, and faster and more power-efficient laser drivers, which are not available off the shelf. Packaging all of the display engine components into a small form factor will require significant efforts in optomechanical engineering and solutions in proper heat transfer. Phase I work will provide the proof of concept studies and design work for the display engine.The broader impact/commercial potential of this project is to satisfy future needs of consumers who will demand ever-larger display capabilities in ever-shrinking mobile devices. Pico-projectors will be used with or integrated into computers, cell phones, PDAs, or other portable electronic devices with an estimated market size of over $1 billion within the next 5 years. Successful commercialization of the proposed high definition pico-projector display engine would have many societal and commercial impacts. Display sizes would be finally decoupled from the limitations of the mobile device sizes. Movies, business presentations, images, social networking web sites, etc. could be more comfortably viewed and shared. There are new possibilities in programmable board-games, adaptive home-decoration, and others. It is believed that the high-resolution (XGA and HD 720p) and highest power efficiency (10 lumens/W) of the proposed technology can fully realize these impacts and capture the markets. This technology, in parallel to the ever-increasing availability of high-speed networks, will in turn increase the ability to more readily share business information and accelerate the distribution of entertainment content even more than it has already.
