SBIR Phase I: Next Generation Displays Based on Novel Carbon Fiber MEMS Micromirrors

这个小企业创新研究第一阶段项目旨在使用新型碳纤维集成微机电（MEMS）结构开发一种创新的高清光栅扫描投影显示系统，用于移动设备和其他应用。目前的技术依赖于硅基MEMS结构，其断裂韧性和疲劳性能较差，无法同时提供投影显示所需的大角度偏转和扫描速度。该项目的研究目标包括制造MEMS元件，测试原型电子和光学系统，将光学和电子封装到便携式原型单元中，并对屏幕材料进行初步研究。预期的技术成果将是一个功能齐全的全彩原型，用于演示小型化MEMS和基于光学的投影显示系统的概念验证。这个项目的更广泛的影响/商业潜力适用于移动设备用户，提供了一个小型的、负担得起的投影系统的潜力，可以嵌入到几乎任何移动设备中，在任何附近的表面上产生大的、高分辨率的图像。移动设备的使用正在迅速扩大，然而5英寸对角线显示器的局限性阻碍了移动设备充分发挥其潜力。该技术的碳纤维MEMS微镜是唯一能够满足快速和大偏转要求的技术，使移动投影显示器能够从移动设备提供类似笔记本电脑的用户体验。这一创新可以通过改进多媒体信息的显示和访问方法来增强技术和科学的理解。社会效益包括改善沟通和多媒体的转移。商业影响是显著的，因为该技术可以集成到大多数手持移动设备中，使便携式视频观看成为可能。

This Small Business Innovation Research Phase I project aims to use novel carbon fiber-integrated microelectromechanical (MEMS) structures to develop an innovative high definition raster-scanned projection display system for mobile devices and other applications. Current technology relies on silicon-based MEMS structures that suffer from poor fracture toughness and fatigue behavior, and cannot provide the simultaneous large angular deflections and scanning speeds necessary for projection display. Research objectives for this project include fabricating the MEMS components, testing the prototype electronics and optics systems, packaging the optics and electronics into a portable prototype unit, and conducting preliminary investigations into screen materials. The anticipated technical results will be a functional, full-color prototype demonstrating proof of concept for a miniaturized MEMS and optics-based projection display system. The broader impact/commercial potential of this project applies to mobile device users, offering the potential of a small, affordable, projection system that could be embedded in almost any mobile device to produce a large, high resolution image onto any near-by surface. Use of mobile devices has been rapidly expanding, however the limitations of a 5" diagonal display prevent mobile devices from achieving their full potential. The proposed technology's carbon fiber MEMS micromirrors are the only demonstrated technology capable of meeting the fast speed and large deflection requirements that enable mobile projection displays capable of providing a laptop-like user experience from a mobile device. This innovation can enhance technological and scientific understanding via an improved method for multi-media information display and access. Societal benefits include improved communication and transfer of multi-media. Commercial impact is significant, as the technology could be integrated into most hand-held mobile devices, enabling portable video-viewing.
