This Small Business Technology Transfer (STTR) Phase II research project focuses on new GaAs-based, low voltage technology for high definition head mounted displays (HMDs), suitable for advanced applications in immersive virtual reality and 3-D imaging. Applications for this technology include battery powered augmented reality HMDs, full color, high resolution HMDs with 3-D imaging potential, and low cost, low voltage indicators and backlights for battery powered electronics. Displays derived from this GaAs technology have superior color gamut, high brightness, resolution and efficiency compared to other approaches. The results obtained from the STTR Phase I project indicate that low cost HMD-based optical systems can be designed using these high resolution microdisplay chips at supply voltages as low as 1.5 volts. Compared to display systems based on GaN LED and OLED technology which require voltages of up to 4 volts, this technology presents a path for continued advancement to 3-D imaging systems that could reach the resolution of the human eye.This technology should impact low cost HMDs displaying low-information content data such as maps, text or line graphics that require long battery life for markets that include first responders, factory and inventory workers, and consumer appliances. The technology can be advanced to much higher resolution microdisplays and improved optics for the high-information content marketplace such as immersive virtual reality for education, medical imaging and surgery, games and videos. Commercial emphasis will be placed on the low voltage operation for battery compatibility, a key advantage for augmented reality HMDs; and one which may lead to fundamental changes in battery powered electronics having indicator lights and/or displays.

该小型企业技术转移(STTR)第二阶段研究项目专注于用于高清晰度头盔显示器(HMD)的基于GaAs的低电压新技术，适用于沉浸式虚拟现实和3D成像中的高级应用。这项技术的应用包括电池供电的增强现实HMD、具有3-D成像潜力的全彩色、高分辨率HMD，以及电池供电电子产品的低成本、低电压指示器和背光。与其他方法相比，基于该技术的显示器具有更好的色域、高亮度、高分辨率和高效率。STTR一期工程的结果表明，使用这些高分辨率微显示芯片，可以在低至1.5伏的电源电压下设计出低成本的基于头盔显示器的光学系统。与基于GaN LED和OLED技术的显示系统需要高达4伏的电压相比，这项技术为继续发展到可以达到人眼分辨率的3D成像系统提供了一条途径。对于包括急救人员、工厂和库存工作人员以及消费电器在内的市场来说，这种技术应该会影响显示低信息含量数据的低成本HMD，如地图、文本或线条图形，这些数据需要较长的电池寿命。该技术可以先进到更高分辨率的微显示器和改进的光学设备，用于高信息内容市场，如用于教育、医学成像和手术、游戏和视频的沉浸式虚拟现实。商业重点将放在电池兼容性的低电压操作上，这是增强现实HMD的一个关键优势；以及可能导致电池供电电子产品具有指示灯和/或显示器的根本变化。
