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，这些投影仪如此小型化、低成本和低功耗，以至于在不久的将来可以与各种移动设备集成在一起，如手机和上网本。拟议的移动视频投影仪的显示引擎由快速调制的RGB(红、绿、蓝)激光组成，通过MEMS扫描镜在显示表面上以高清(高清晰度)视频速率逐个像素扫描。由于使用了激光，这样的投影图像将不需要在任何距离上对焦，并且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反射镜之外，拟议的系统还可能需要创新的封装，以及更快和更省电的激光驱动器，这些都是现成的。将所有显示引擎组件封装到一个小尺寸中将需要在光学机械工程方面付出巨大努力，并解决适当的热传递问题。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验证。该项目更广泛的影响/商业潜力是满足消费者未来的需求，这些消费者将在不断缩小的移动设备中要求越来越大的显示能力。Pico投影仪将与计算机、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。拟议的高清晰度微微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、图像、社交网络网站等可以更舒适地查看和共享。在可编程棋盘游戏、适应性家居装饰等方面都有新的可能性。相信建议技术的高分辨率(XGA和HD 720P)和最高能效(10流明/瓦)可以充分实现这些影响并占领市场。在高速网络可用性不断提高的同时，这项技术将反过来提高更容易地共享商业信息的能力，并比以往更快地加快娱乐内容的分发。

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.
