The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to enable superior digital displays with better cost, power, and performance. Today's typical solutions include liquid crystal displays (LCDs) and organic light emitting diodes (OLEDs). LCDs require many layers of materials, each of which adds cost, reduces efficiency, and increases fragility; OLEDs are typically even more expensive to make and degrade faster than LCDs. This project proposes a manufacturing process for an improved display assembled from arrays of very small light sources. These displays will enable advances in many applications of low-cost, lightweight displays, such as artificial and virtual reality headsets, automotive consoles, wearables, medical devices, and mobile devices.This Small Business Innovation Research (SBIR) Phase I project develops a manufacturing process to place millions of microelectronic components, such as micro-scale light emitting diodes (microLEDs) onto substrates with the required accuracy to build functional displays. Conventional approaches use basic mechanical tooling to pick up each microLED from a source wafer and place it on the target circuit board. The objective of this project is to develop a manufacturing process consistent with yield, cost, and performance requirements. The project is based on properties of polymers related to those used in photolithography. When illuminated by light, the polymers vaporize and cause components adhered to them to be transferred to a substrate, moving millions of microLEDs in a single, cost-effective step. This research will advance this technology toward translation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小型企业创新研究 (SBIR) 第一阶段项目的更广泛影响/商业潜力是实现具有更好成本、功耗和性能的卓越数字显示器。 当今的典型解决方案包括液晶显示器 (LCD) 和有机发光二极管 (OLED)。 LCD 需要多层材料，每层材料都会增加成本、降低效率并增加脆弱性； OLED 的制造成本通常比 LCD 更高，而且降解速度更快。 该项目提出了一种由非常小的光源阵列组装而成的改进显示器的制造工艺。 这些显示器将推动低成本、轻量级显示器的许多应用取得进步，例如人工和虚拟现实耳机、汽车控制台、可穿戴设备、医疗设备和移动设备。这个小型企业创新研究 (SBIR) 第一阶段项目开发了一种制造工艺，可将数百万个微电子元件（例如微型发光二极管 (microLED)）放置在具有所需尺寸的基板上。 构建功能显示器的准确性。传统方法使用基本机械工具从源晶圆上拾取每个 microLED 并将其放置在目标电路板上。该项目的目标是开发符合产量、成本和性能要求的制造工艺。 该项目基于与光刻中使用的聚合物相关的特性。 当受到光照射时，聚合物会蒸发，并使粘附在其上的组件转移到基板上，从而通过一个经济高效的步骤移动数百万个 microLED。这项研究将推动这项技术走向转化。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
