Toward opal-based billboards?
“Nature News reports that British and Canadian chemists have developed synthetic opals that can very quickly switch between various colors when a few volts of electricity are applied to them. The developers, who said they’re ready to sell the technology today, added that their ‘photonic ink’ (P-Ink) material could soon be used in electronic books or advertising displays. [...] This “is an opal-based technology that provides electrically tunable color of any wavelength. By coating this material onto an array of pixels, a full-color display can be created wherein the color of each pixel can be varied at will. Switching of a P-Ink pixel in response to a voltage increasing from left to right.”
