The objective of this NSF GOALI proposal is to pursue a novel color e-Paper through a 3-year collaborative effort between the University of Cincinnati, Hewlett Packard (Corvallis), and EMD/Merck Research Labs (Boston, Southampton). The central hypothesis is that a new bi-primary color system can provide transformative e-paper reflectance (~76%) and color gamut (40%), using an electrokinetic pixel and dual-particle ink dispersions. The academic-industry team has formulated this hypothesis on the basis of preliminary data, and previous collaborative publishing on the state-of-the-art in e-Paper technology. The intellectual merit is three-fold: (1) exploring the fundamental electrophoretic behavior of dual-color, dual-particle ink dispersions, including understanding the effects of poly-dispersity and zeta-potentials for clean particle transport; (2) optically engineering pixels for 2X reflectance and 2X color-fraction of conventional RGBW color-filtering; (3) implementing electrical control by active-matrix addressing and optically characterizing the improved performance as a function of ambient lighting conditions (diffuse, directional, etc..). The broader impacts center on undergraduate students who will be trained as research co-ops at the University of Cincinnati, followed by industry co-op experience at GOALI partner companies. In terms of societal benefit, e-paper is 10X more energy efficient than a typical LCD. Furthermore, e-paper benefits to the individual include improved e-reader ergonomics (less weight, larger screen size, unbreakable plastic display, rollable/foldable form-factor), and enable further immersion of society in the growing sectors of e-publishing and tablet-based learning.

NSF GOALI 提案的目标是通过辛辛那提大学、惠普（科瓦利斯）和 EMD/默克研究实验室（波士顿、南安普顿）之间为期 3 年的合作，开发一种新颖的彩色电子纸。 中心假设是，新的双基色系统可以使用动电像素和双粒子墨水分散体提供变革性的电子纸反射率（约 76%）和色域（40%）。 学术界和工业界团队根据初步数据和之前关于最新电子纸技术的合作发表的成果，提出了这一假设。 其智力价值有三个方面：(1) 探索双色、双颗粒墨水分散体的基本电泳行为，包括了解多分散性和 zeta 电位对清洁颗粒传输的影响； (2) 光学工程像素实现 2 倍反射率和 2 倍传统 RGBW 滤色的颜色分数； (3) 通过有源矩阵寻址实现电气控制，并以光学方式将改进的性能表征为环境照明条件（漫射、定向等）的函数。更广泛的影响集中在本科生身上，他们将在辛辛那提大学接受研究合作培训，然后在 GOALI 合作伙伴公司获得行业合作经验。就社会效益而言，电子纸的能效比典型液晶显示屏高 10 倍。 此外，电子纸对个人的好处包括改进的电子阅读器人体工程学（重量更轻、屏幕尺寸更大、不易破碎的塑料显示屏、可卷曲/可折叠的外形），并使社会进一步融入不断发展的电子出版和电子行业。基于平板电脑的学习。
