Light guide of Au nanostructures for color-filterness optoelectronic display devices

Au line nanostructures with different pitch distances from 500 nm to 950 nm on ITO coated glass substrates have been fabricated at room temperature for exploring the color light guide in all kinds of display system. The patterned Au line array is used as a light outcoupling and color-selection component due to the emission wavelength changed by the Au line arrays with different pitch distances that could achieve multi-color selections. The ITO coated glass substrates patterned with periodic Au line arrays with controlled line pitches has been demonstrated and used as a color filter in all display devices. Using a proper pitch distance of Au line nanostructures, the basic third colors of red, green, and blue (RGB) can be simply gained and controlled without a traditional color filter for future optoelectronic display devices.
