The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to simplifying the display backplane manufacturing process and thereby deliver cost savings to a display industry annually losing billions of dollars. The technology being developed as part of this Phase II project has the potential to outperform current thin film transistor (TFT) backplane technologies in key Liquid Crystal Display (LCD) performance areas such as power consumption, image brightness and quality, and color richness. The vision of this project is to redefine the cost, manufacturability and performance of displays through the use of advanced materials and novel electronics. Beyond dramatic economic implications for the LCD industry, the amorphous metal and metal oxide-based technologies developed through this project will enable a technically and economically viable path to roll-to-roll production of flexible glass displays. Enabling a roll-to-roll "flex" factory could reintroduce display manufacturing to the United States. This Small Business Innovation Research (SBIR) Phase II project challenges conventional display industry practice by eliminating semiconductor content and relying on quantum tunneling conduction enabled by innovative materials to control the LCD backplane. The relatively simple tunneling devices developed as part of this project contrast with the industry's focus on increasingly complex semiconductors and manufacturing processes to meet the performance demands of UHD TV while reducing cost. The use of these structurally less complex tunneling devices in the LCD backplane has been enabled through the use of amorphous metal thin-films. The objective of this Phase II project is to develop a prototype display incorporating amorphous metal thin-film based tunneling devices and to evaluate its performance in terms of gray-scale control, power consumption, and maximum refresh rate. It is anticipated that amorphous metal tunneling devices can outperform current TFT technologies in these three areas by enabling 12-bit gray-scale accuracy, increasing the sub-pixel aperture ratio, and eliminating the need for semiconductor materials. The results from this prototype will confirm the technology's core value proposition, amorphous metal thin-film devices improve UHD performance while reducing manufacturing cost and increasing factory capacity.

这项小型企业创新研究（SBIR）II阶段项目的更广泛的影响/商业潜力是简化显示背板制造过程，从而为每年损失数十亿美元的展示行业节省成本。 作为该阶段项目的一部分，该技术在关键的液晶显示（LCD）性能领域（例如功耗，图像亮度和质量以及色彩丰富度）中超过当前薄膜晶体管（TFT）背板技术的潜力。 该项目的愿景是通过使用高级材料和新型电子产品来重新定义显示的成本，制造性和性能。除了对LCD行业的巨大经济影响之外，通过该项目开发的无定形金属和基于金属的基于金属的技术将使技术和经济上可行的途径能够滚动到弯曲的弹性玻璃显示器。 实现卷到滚动的“ Flex”工厂可以重新引入美国的展示制造。 这项小型企业创新研究（SBIR）II期项目通过消除半导体内容并依靠创新材料来控制LCD背板来挑战常规展示行业实践。 相对简单的隧道设备作为该项目的一部分开发了鲜明对比的是该行业对日益复杂的半导体和制造过程的关注，以满足UHD电视的性能需求，同时降低成本。 通过使用无定形金属薄膜，已实现了LCD背板中这些结构上不那么复杂的隧道设备的使用。 该阶段项目的目的是开发一个原型显示，其中包含基于非晶的金属薄膜隧道设备，并在灰度控制，功耗和最大刷新率方面评估其性能。 可以预计，无定形的金属隧道设备可以通过实现12位灰度的精度，增加子像素孔径比，并消除对半导体材料的需求，从而超过这三个区域的TFT技术。 该原型的结果将确认该技术的核心价值主张，无定形金属薄膜设备可改善UHD性能，同时降低制造成本并增加工厂容量。
