该项目的目标是探索一种新型的频谱滤光器，可以提高LCD显示器的能效，并潜在地收集显示介质的能量。与业界的合作将使大面积的原型能够被制造出来，并为显示应用进行评估。智能的优点是利用纳米光子元件的共振效应进行能效频谱过滤，并可使其与LCD操作兼容。非透射光可以回收利用。还提出了一种能量采集方案，将光伏功能集成到显示滤色器中，可以采集环境光和/或背光能量。在这种光伏集成显示系统中，金属线栅作为透明电极提供了多种功能。更广泛的影响是开发变革性的新技术和教育计划，使平板显示器和光伏领域受益。当今世界对能够显著提高能源效率的技术的需求很高。这项拟议的研究为显示和成像系统中使用的频谱滤光器提供了一种范式变化，并为移动计算应用程序收集能量指明了一个新的方向。这项研究的研究部分将通过整合教育和宣传部分而得到加强。

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.
