This Small Business Innovation Research (SBIR) Phase II project will create electronic paper displays from a new e-paper technology that promises substantially improved black and white contrast, bright color images, multimedia/internet update speeds, and zero power image hold. The technology, an electrofluidic pixel that uses voltage to move a colored pigment in a fluid, is capable of achieving twice the reflectivity of existing e-paper solutions. This improvement in reflectivity enables the color saturation found in printed media. The multi-stable pixel designs demonstrated in the Phase I program make possible zero power images with grayscales. The Phase II research project will develop the technology for complete electronic paper displays incorporating this new pixel technology that are robust and manufacturable, and that achieve record reflectance (~ 70%). The first prototypes to be designed and created will be simple information content displays with simple electrical drive, such as electronic shelf labels. The later stage prototypes will be e-Reader displays with active matrix backplanes.The broader impact/commercial potential of this project is the widespread replacement of paper-media with electronic paper, providing superior low power products to the current burgeoning market. In particular, the improvements demonstrated in this project enable saturated colors and multimedia "video" rates with a zero-power image hold, thereby overcoming performance barriers that have blocked low power color electronic books from entering the market. For example, this technology could replace a stack of textbooks with a single lightweight color multimedia tablet. The market opportunity is easily in excess of $10B, and will support numerous new U.S. jobs under a business model providing a sustainable economic benefit to the U.S.A. Multi-stable electrofluidic technology is also well suited for both small and large electronic signage applications.

这个小型企业创新研究（SBIR）第二阶段项目将从一个新的电子纸技术，承诺大大提高黑色和白色对比度，明亮的彩色图像，多媒体/互联网更新速度，和零功率图像保持创建电子纸显示器。 该技术是一种电流体像素，利用电压移动流体中的有色颜料，能够实现现有电子纸解决方案的两倍反射率。 反射率的这种改善使得能够在印刷介质中找到颜色饱和度。 在第一阶段计划中展示的多稳定像素设计使灰度级零功率图像成为可能。 第二阶段的研究项目将开发完整的电子纸显示器技术，结合这种新的像素技术，这种技术是强大的，可制造的，并达到创纪录的反射率（~ 70%）。 第一个原型将被设计和创建将是简单的信息内容显示与简单的电力驱动，如电子货架标签。 该项目的更广泛的影响/商业潜力是用电子纸广泛取代纸介质，为当前蓬勃发展的市场提供上级低功耗产品。 特别是，在这个项目中展示的改进，使饱和的颜色和多媒体“视频”速率与零功率图像保持，从而克服性能障碍，阻止低功率彩色电子书进入市场。 例如，这项技术可以用一个轻量级的彩色多媒体平板电脑取代一堆教科书。市场机会很容易超过100亿美元，并将在商业模式下支持许多新的美国就业机会，为美国提供可持续的经济利益。
