TLDR
A tunable polarization-independent reflective surface where the colour of the surface is changed as a function of applied voltage is demonstrated, paving the way towards dynamic pixels for reflective displays.Abstract:
Structural colour arising from nanostructured metallic surfaces offers many benefits compared to conventional pigmentation based display technologies, such as increased resolution and scalability of their optical response with structure dimensions. However, once these structures are fabricated their optical characteristics remain static, limiting their potential application. Here, by using a specially designed nanostructured plasmonic surface in conjunction with high birefringence liquid crystals, we demonstrate a tunable polarizationindependent reflective surface where the colour of the surface is changed as a function of applied voltage. A large range of colour tunability is achieved over previous reports by utilizing an engineered surface which allows full liquid crystal reorientation while maximizing the overlap between plasmonic fields and liquid crystal. In combination with imprinted structures of varying periods, a full range of colours spanning the entire visible spectrum is achieved, paving the way towards dynamic pixels for reflective displays.read more

TL;DR: Plasmonic colours are structural colors that emerge from resonant interactions between light and metallic nanostructures as mentioned in this paper, which can be used to colour large surfaces, can be mass-produced and dynamically reconfigured, and can provide sub-diffraction resolution.

Printing colour at the optical diffraction limit
TL;DR: The colour-mapping strategy produces images with both sharp colour changes and fine tonal variations, is amenable to large-volume colour printing via nanoimprint lithography, and could be useful in making microimages for security, steganography, nanoscale optical filters and high-density spectrally encoded optical data storage.

Photonic-crystal full-colour displays
TL;DR: There is an intense drive at the moment towards paper-like displays, devices having a high reflectivity and contrast to provide viewability in a variety of environments, particularly in sunlight where emissive or backlit devices perform very poorly.

Solid Surface Shape and the Alignment of an Adjacent Nematic Liquid Crystal
TL;DR: This article showed that elastic strain energy may account for the tendency of some nematic liquid crystals to lie parallel to the direction of rubbing on a solid surface that has been slightly deformed by rubbing, or perpendicular to a surface that is slightly rough in two dimensions.

Plasmonic nanoresonators for high-resolution colour filtering and spectral imaging
TL;DR: This article uses selective conversion between free-space waves and spatially confined modes in plasmonic nanoresonators formed by subwavelength metal-insulator-metal stack arrays to show that the transmission spectra through such arrays can be well controlled by using simple design rules, and high-efficiency colour filters capable of transmitting arbitrary colours can be achieved.
