This Small Business Innovation Research (SBIR) Phase II project evaluates the feasibility of constructing vivid, full-color, reflective display modules for large-area outdoor digital signage driven by dielectric elastomers suitable for pilot testing. Completion of Phase II objectives is expected to have the following impact: Commercially, the availability of new signage products will create significant economic impact through partial capture of the $14.2B domestic billboard and sign manufacturing market. Up to 10% of US zoning codes are estimated to prohibit LED-based (light emitting diode) signage while potentially permitting a reflective digital signage technology, expanding the domestic market up to $5.6B, with a 10x impact worldwide. Environmentally, greenhouse gas reduction is expected as an alternative to LED-based technology; up to 40x reduction in energy consumption is anticipated relative to LEDs. Additionally, billboard wrap waste will be reduced by replacing printed signage. Scientifically, the use of dielectric elastomers as a class of materials in products would be promoted through addressing technological and manufacturing hurdles currently limiting market translation. Societally, increased impact from timely public service announcements on digital billboards displayed during natural disasters, when catching fugitives from the FBI?s Most Wanted lists, and with Amber/Silver alerts are expected through large-area digital sign proliferation.In phase II, electroactive polymer-based proof-of-concept display modules will be constructed and tested, ready for pilot testing with initial customers. The low-cost display design uses unique electro-hydraulic driving principles to enable exceptional refractive index matching within the optical stack for highly vivid and reflective full-color generation. In phase I, a functional proof-of-concept pixel array module was fabricated using scalable processes. To achieve pilot readiness, improvements in performance, resolution, and calibration to meet advertiser standards are needed, as well as environmental qualification for outdoor operation, development of industry-conscious software control, and qualification of supply chain inputs to enable further production at scale. Phase II research will address these technical challenges by introducing process refinements and quality control standards, conduct color calibration using existing techniques, perform industry-relevant environmental testing, work with vendors to source soft-tooled components, and develop module and multi-module control software. The result of phase II efforts will be a calibrated and rugged one square foot, full-color, 16mm pitch, reflective display module ready for scaling to pilot production following phase II.

该小型企业创新研究 (SBIR) 第二阶段项目评估了为大面积户外数字标牌构建生动、全彩、反射式显示模块的可行性，该显示模块由适合试点测试的介电弹性体驱动。 第二阶段目标的完成预计将产生以下影响： 在商业上，新标牌产品的可用性将通过部分占领 $14.2B 的国内广告牌和标牌制造市场来产生重大的经济影响。 据估计，多达 10% 的美国分区法规禁止基于 LED（发光二极管）的标牌，同时可能允许反射式数字标牌技术，从而将国内市场扩大至 $5.6B，在全球范围内产生 10 倍的影响。 在环境方面，温室气体排放有望成为 LED 技术的替代方案；相对于 LED，预计能耗可减少高达 40 倍。此外，通过更换印刷标牌将减少广告牌包装材料的浪费。从科学角度来看，通过解决目前限制市场转化的技术和制造障碍，可以促进介电弹性体作为一类材料在产品中的使用。在社会上，在自然灾害期间、在抓捕联邦调查局头号通缉犯名单上的逃犯时以及在大面积数字标牌扩散的情况下，数字广告牌上显示的及时公共服务公告预计会产生更大的影响。在第二阶段，电活性将构建和测试基于聚合物的概念验证显示模块，为初始客户进行试点测试做好准备。 低成本显示器设计采用独特的电动液压驱动原理，可在光学堆栈内实现出色的折射率匹配，从而生成高度生动和反射的全彩。 在第一阶段，使用可扩展工艺制造了功能性概念验证像素阵列模块。 为了实现试点准备，需要改进性能、分辨率和校准以满足广告商标准，以及户外操作的环境资格，开发行业意识的软件控制，以及供应链输入的资格，以实现进一步的大规模生产。 第二阶段研究将通过引入工艺改进和质量控制标准来解决这些技术挑战，使用现有技术进行颜色校准，执行行业相关的环境测试，与供应商合作采购软工具组件，以及开发模块和多模块控制软件。 第二阶段工作的结果将是一个经过校准且坚固耐用的一平方英尺、全彩、16毫米间距、反射式显示模块，准备在第二阶段之后进行试生产。
