This Small Business Innovation Research Phase I project assesses the technical feasibility of the amorphous metal non-linear resistor as a transformational display technology. This technology challenges conventional display industry wisdom by using tunneling electronics, enabled through innovative materials, to simplify the active matrix liquid crystal display backplane. A new path is defined for realizing enhanced performance that goes beyond simply adding process complexity to achieve incremental gains. The amorphous metal non-linear resistor has no semiconductors, fewer process layers than traditional thin-film transistor based backplanes, and leverages inherently flexible amorphous materials. These qualities are allowing cost-to-performance expectations to be redefined by solving transistor stability and speed issues and by ultimately enabling a new path to roll-to-roll backplane manufacturing. The project will establish a process for producing amorphous metal non-linear resistors that is compatible with high-volume display manufacturing techniques. At the same time, the project will advance knowledge by developing an improved understanding of the materials and interface properties necessary for realizing and controlling Fowler-Nordhiem conduction in fully patterned structures.The broader impact/commercial potential of this project is in liquid crystal display backplane manufacturing energy and cost reduction. Amorphous metal non-linear resistor technology, with fewer steps, reduces the energy used in display backplane fabrication. By proving the stability and reliability of amorphous metal based thin-film devices, this technology will fundamentally alter the traditional suite of materials that scientists and engineers use to design electronics beyond display applications. Current industry solutions that attempt to improve active-matrix-liquid-crystal display performance, e.g., low temperature polysilicon and amorphous oxide semiconductor thin-film transistors, only increase manufacturing complexity and energy costs. Roll-to-roll processing of display backplanes on flexible glass substrates is a proposed cost savings initiative in the display industry. Amorphous metal nonlinear resistor technology, offers further commercial benefit to the display industry through enabling roll-to-roll production of flexible display backplanes.

这个小型企业创新研究阶段I项目评估了无定形金属非线性电阻器作为变革性显示技术的技术可行性。这项技术通过使用创新材料启用的隧道电子设备来挑战传统的展示行业智慧，以简化活跃的矩阵液晶显示背板。为实现增强性能而定义了一条新的路径，这不仅仅是添加过程复杂性以实现增量增益。无定形金属非线性电阻没有半导体，比传统的薄膜基晶体管背板少，过程层较少，并且利用固有的柔性无定形材料。这些素质可以通过解决晶体管稳定性和速度问题来重新定义绩效的期望，并最终为滚动到滚动背板制造的新途径。该项目将建立一个生产与大量显示器制造技术兼容的无定形金属非线性电阻的过程。 同时，该项目将通过对实现和控制完全模式的结构中的Fowler-Nordhiem传导所必需的材料和界面特性的了解来提高知识。该项目的更广泛的影响/商业潜力在液晶显示器制造能量和成本降低中。 具有较少步骤的无定形金属非线性电阻技术可减少显示背板制造中的能量。 通过证明非晶质金属薄膜设备的稳定性和可靠性，该技术将从根本上改变科学家和工程师用来设计超出显示应用程序的电子设备的传统材料套件。 当前试图改善主动型液体液体晶体显示性能的行业解决方案，例如低温多硅烷和无定形氧化物半导体薄膜晶体管，只会增加制造的复杂性和能源成本。 在弹性玻璃基材上显示背面的滚动处理是在展示行业中提出的一项成本节省计划。无定形的金属非线性电阻技术，通过实现柔性显示背板的滚动生产，从而为展示行业提供了进一步的商业利益。
