Abstract:
Nano-structures represent a class of materials with nano-scale features which can be engineered to manipulate light beyond the limit of diffraction. By tuning the structure geometries and material compositions, nano-structures can act as color pixels which have wide applications in imaging and display devices [Yokogawa et al. 2012].
Producing a color image using nano-structures can be very time consuming and is currently a major challenge in applying nanostructures in displaying visual information. Usually, high resolution nano-patterning techniques, such as electron-beam lithography, are used to generate nano-structures according to the desired color image onto a substrate, and the nano-structures are replicated thereafter using nano-imprint lithography technique. Despite the breakthroughs in the nano-fabrication technology in recent years, the entire fabrication process still remains slow and expensive, because each color image would require a new nano-pattern being generated.
In the technology presented in this poster, called ‘Nano-Media’, we provide an alternative solution to the existing challenges, which allows any color image to be rapidly printed using nano-structures as pixels.
