纳米金属光栅的透射光谱对临近材料折射率变化非常敏感,可以通过改变介质折射率实现可调的彩色滤光,将双层纳米金属光栅应用于显示装置上具有工艺制备简单、色度和对比度高等特点。采用纳米金属光栅结构,通过严格耦合波理论模拟和表面等离子体共振原理设计了一种新型的透射式电润湿显示器件。在650nm周期、空气环境下,通过数值优化在690nm波长处得到了50%的单色透射,而在水溶液的环境下,由于共振移动到红外,可以实现黑态显示,从而验证了灰度的可调。该研究将为轻薄、节能和高分辨率的新型电浸润显示器件设计提供全新思路。 The transmittance spectrum of the nano-metal grating is very sensitive to the change of the refractive index of the adjacent materials. The tunable color filter can be realized by changing the refractive index of the medium. The double-layer nano-metal grating is applied to the display device and has the advantages of simple preparation, high chroma and contrast Features. A novel transmission electrowetting display device is designed by using the principle of nanometer metal grating and the strict coupled wave theory and surface plasmon resonance principle. In the 650 nm period, the numerical optimization achieves a 50% monochromatic transmission at 690 nm in air, while in the aqueous environment, the black state can be achieved due to resonance moving to the infrared, thus verifying the Tune The research will provide a whole new idea for the design of thin, energy efficient and high resolution new electro wetted display devices.
