The objective of this program is to explore a new class of spectrum filters that can increase the energy efficiency of the LCD displays and potentially energy-harvesting display media. Collaborating with industry will allow large area prototype to be fabricated and evaluted for display applications. The intellectual merit is to exploit resonance effect of nanophotonic elements for energy efficiency spectrum filtering, and can be made compatible with LCD operation. Non-transmitted light can be recycled. An energy harvesting scheme is also proposed by integrating photovoltaic function into the display color filters that can harvest the ambient light and/or the backlight energy. The metal wire grid acting as transparent electrode provide multiple functions in such photovoltaic-integrated display system. The broader impacts are to develop transformative new technology and education program that will benefit the flat panel display and photovoltaics fields. Technologies that can provide significantly improved energy efficiency are in high demand in our world today. The proposed research provides a paradigm change to the spectrum filters used in display and imaging systems, and points to a new direction to harvest energy for mobile computing applications. The research component of this research will be enhanced by the integration of the education and outreach components.

该计划的目标是探索一种新型光谱滤波器，可以提高 LCD 显示器和潜在能量收集显示介质的能源效率。与业界的合作将允许制造大面积原型并针对显示应用进行评估。其智力优势是利用纳米光子元件的共振效应进行能效频谱过滤，并且可以与LCD操作兼容。未透射的光可以回收。还提出了一种能量收集方案，通过将光伏功能集成到显示器滤色器中，可以收集环境光和/或背光能量。作为透明电极的金属线栅在这种光伏集成显示系统中提供多种功能。更广泛的影响是开发变革性的新技术和教育计划，这将有利于平板显示和光伏领域。当今世界对能够显着提高能源效率的技术的需求很高。拟议的研究为显示和成像系统中使用的频谱滤波器提供了范式改变，并指出了为移动计算应用收集能量的新方向。这项研究的研究部分将通过教育和推广部分的整合得到加强。
